On November 11, 143 of the Pandora Era, at a time when all things were being slaughtered, individuals sent by Wei Keng began to follow Zeng Lin northward.
This individual was codenamed "Zhen Xin Zheng". After Zeng Lin set off from the checkpoint in the north of Shaoguang City, he rode a mechanical beast all the way north through southern Gansu. Along the way, there were large areas of barbaric areas occupied by traditional genetic communities.
.
This mountainous area fully reflects the strange ecology of Pandora.
There is a wolf that walks upright. The difference from the werewolves in old-era literature is that its two hands are crayfish pincers.
A puppy with a constant temperature system and an ant head.
There are also willow trees that secrete mucus comparable to that of a mouse board.
Fortunately, there was a lot of ammunition prepared, the mechanical vehicles were very powerful, and Zeng Lin was also familiar with this area, otherwise the team would really have been unable to move forward.
"Zhen Xin Zheng" rode a mechanical wolf and successfully passed through the 200-kilometer wilderness area of southern Jiangxi. - For this area, the Wei Keng cluster has only one evaluation, which is that it is not popular.
After passing through the wild areas of southern Jiangxi, we encountered human city-states in the central area of Jiangxi.
Wei Keng jumped off the tractor-like cart and wanted to buy some souvenirs here. As a result, he was slapped with five steel coins before he took two steps. The reason was that the vehicle tax to enter the city gate was a car tax, and people were
There is an additional tax when you get off the bus.
Wei Keng defended: "I just went to the toilet!" The guards: "Those who use the toilet also have to pay health tax."
Fortunately, Zeng Lin was very familiar with the nobles here, and after showing his badge, he came to the rescue of Wei Keng.
When meeting with the city lord in the evening, the nobles here had heard about the changes taking place in the Pearl River District in the south, and were deeply saddened by the changes in Zeng Lin's family.
As the origin of the incident, "Zhen Xin Zheng" did not intervene.
…
The trade team heading north pawned their transport machinery at the city-states in central Jiangxi, then put on animal carts and continued northward.
Following this, we passed through four military checkpoints.
These military checkpoints were built very grandly, with thick reinforced concrete buildings. Such a forty-meter-high fortification group stretching for dozens of kilometers made Wei Keng take a second look.
Zeng Lin introduced to Wei Keng that before the biological disaster broke out, when the human government was still functional, railways were mobilized, a large amount of cement and steel bars were transported, and the central Jiangxi fortress area was built to isolate the genetic community in the southern mountainous area from the Yangtze River genetic community in the north.
Genetic intersection between communities.
Although 70% of them were later ineffective, with the re-emergence of human city-states in the Yangtze River, this place was used again, with a large number of elite trainers taking turns to garrison it.
Even if this fortress group is just a military facility built for small-scale battles, the ecological isolation effect between the two places is obvious.
The river in the north is a water system environment, and the survival of the fittest genes maintains the biological characteristics of water system organisms that are highly resilient, resistant to hunger, and able to hibernate in the soil.
The creatures in the southern mountains are smaller in size, but have strong explosive power and maintain a certain degree of eusocial communication ability.
Once the biological genes of the two regions are exchanged, a community will be born that possesses the advantageous genes of both places. Moreover, such genetic communities will also maintain migratory characteristics, which will in turn pose a greater threat to the city-states in the Yangtze River Basin.
Therefore, although the city-state alliance in the Yangtze River Basin took over this defense line, although it cost money, it ensured the safe development of human city-states in the lower reaches of the Yangtze River in the north.
Zhen Xin was looking at the mottled city wall, the stalactites growing out of the raindrops, and determined that this was a very old building.
Wei Kengqun sighed inexplicably: "The Great Wall is built in the south?"
…
Walking out of the military checkpoint, the city walls on both sides of the road quickly changed from high to short, and then disappeared. From then on, it was a road with the standard width of the Yangtze River city-states.
This road network was obviously much more prosperous. After walking for ten kilometers, I saw more than 30 beast-of-pack vehicles covered with straw mats approaching.
Subsequently, the southern caravan traveling with Zeng Lin had delivered goods and began to separate from the two of them. They just transported the goods here, and going further north was no longer a place for them to trade.
After the Great Depression, commerce was a regional monopoly, and you could only ship some goods to this region!
Zeng Lin and Wei Keng changed their means of transportation in a city-state area in the ruins of Jiujiang, and began to take a steamship, heading towards Jianye, the holy lighthouse of humanity in the south.
Zeng Lin showed a gold medal, and the steamer's ticket inspector scratched it.
Wei Keng looked at it curiously. Zeng Lin's gold medal is equivalent to a card. There are a large number of small grids of about one millimeter. If you scratch it, it is equivalent to paying a fee in the Yangtze River public transportation system or the inn system.
money.
Although primitive, it shows that the economic system in this area is unified.
There are also electric lights and even refrigerated warehouses on the steamship, which makes the Wei Keng cluster admire the ability of the northern civilization system to maintain part of the old civilization.
System: "The hydraulic transportation capacity of the Yangtze River is very strong. It was able to maintain a large city with a population of 600,000 in the classical era. The current human settlements centered on Jianye still have a population of more than 5 million. This population base can
Let it maintain key technologies such as gas turbines and high-voltage substations. It will take more than 40 years for it to weaken."
Zhen Xinzheng: “Well, weakening after forty years?”
The system opened the information, which was discovered by other time travelers on this timeline, and revealed the future fate of human city-state forces.
…
After entering the Yangtze River main road, Zhenxin saw the foggy river, unable to see the other side at a glance. As far as the eye could see, tens of millions of tons of river water surged eastwards in a unified way within a visual range of thousands of meters.
(The flow of the Yangtze River is about 33,000 cubic meters per second). In nature, such an orderly and grand phenomenon will convey a heroic association to those who see it.
As an individual, Zhenxin went deep into the Jianghuai area of Pandora's world. He had a trembling feeling of walking on the edge of a cliff. This was a feeling that he had not seen for a long time after Pandora entered the group.
At noon, the alarm bell rang from the bow of the ship,
Zhenxin was standing on the side of the ship, looking around. After a while, he spotted fins surging on the river, and couldn't help but pick up the telescope. After a few seconds, Wei Keng was sure that it was a finless porpoise, but it didn't seem to be exactly that. How could it be?
The finless porpoise is six meters long, and the spout on its head is like an elephant's trunk!
The system brought up the information for Wei Keng Science: This is a new species group dominated by finless porpoise genes. After human civilization experienced a great collapse, Pandora Field provided a network for genetic exchange for species around the world, so that many species that were reborn in the past were
The species that were suppressed were suddenly exposed to the sun.
The terrestrial freshwater ecological niche can originally provide the birth of species exceeding three meters. That is to say, terrestrial species like humans have invented tools like fishing nets to take food into the freshwater ecological niche unprecedentedly, and the hunting efficiency surpasses the evolution of all deep-water species.
, only then will the top of the freshwater ecological niche suddenly become decadent.
After the sudden collapse of human civilization, the bottom layer of fresh water suddenly became rich. There was no net to eliminate households, and there was no propeller of a 10,000-ton giant ship that could create supercavitation.
It took the finless porpoise a hundred years to become a dominant creature in the area with the blessing of Pandora Field. Its internal skeleton also began to strengthen, and it can survive the rainy season from mid-June to early July every year, just like the mudskipper.
With the blessing of heavy rainstorms, they rush from one body of water to another.
In front of Wei Keng, the system listed four mainstream directions in the process of biological variation of finless porpoises:
One is an eel-shaped lake species;
One is a completely streamlined, high-speed type with a water drop shape;
There is also a kind of old Yinbi that is as flat as a turbot fish and clings to the shore to play raids;
The last one has completely given up speed, and its two pairs of forelimbs have been specialized into thin and long webs. It doesn't look like it has any combat effectiveness? Well, it is directly discharged.
Weikeng Consciousness Group: “Life is really about working very hard to survive.”
But a few seconds later, he suddenly asked: "By the way, there are alligators in the Yangtze River, how are they now?"
The system has switched the pattern.
Wei Keng looked at the mark on the scale that the existing alligator gene could reach, and asked in astonishment: "Why has it shrunk? Well, this~"
Subsequently, he saw a migration map and understood.
Different from the ecological world before Pandora's era, genes depended on the migration of species.
In the Pandora field era, genes must be kept in sufficient quantities in an area to be stably preserved. There will never be a situation where a small group of foreign species land and suddenly reproduce indefinitely and wipe out the native species. In other words, there are no invasive species.
this concept.
Now in the lower reaches of the Yangtze River, when the finless porpoise has occupied the main genetic position of large species in this type of environment, the alligator has been squeezed out. It must either reduce its size and give up the ecological niche of large species, or find its own genetic communities in the south and north.
position.
Alligator alligators maintain the gene for large size, which has just been exterminated in the past few years. They are the dragon species of the Dongting community a few years ago, but now Dongting Lake has been replaced by the Chongqing gene.
The last time Wei Keng came, he set fire to the mountains and caused the first ecological disaster, forcing the Guangdong genetic community to move northward. As a result, the Dongting Lake genetic community exploded and expanded, and then went south, where it was beaten again by Wei Keng.
After a while, he returned to the north again.
In the end, Chongqing City took advantage of it, and now the large-scale ecological niche of Dongting Lake has been occupied by the otter system.
In this era, although humans are no longer strong, biological communities with huge genetic gaps are fighting each other, causing extinction to continue.
The only difference is that the number of humans is also constantly decreasing.
…
When Wei Keng wants to see the finless porpoise further,
The crew warned Wei Keng and asked him to return to the steamer. As Wei Keng retreated, layers of rolling metal doors were pulled down, forming layers of armor. (When various stores in the 21st century are closed for the New Year, they are pulled down.
The lower layer of metal roller blinds.)
Zeng Lin took Zhenxin into the uppermost captain's cabin of the steamship. The crew looked like they were facing a formidable enemy, which made Zhenxin a little curious.
In Wei Keng's impression, the things flapping in the water are cute and friendly to humans, just like killer whales. How are they threatening the humans on the boat now? Are they jumping up and biting people? There are railings, how is that possible?
You can jump up.
Two minutes later,
The finless porpoise jumped out of the water. Before Wei Keng could appreciate its heroic appearance, the ten-meter-long big guy seemed to grin and then swing it up with the trunk of an elephant.
With a bang, a projectile struck directly.
Zhenxin was looking at the banging rolling shutter door that had been smashed and the scattered gravel powder, and the corner of his mouth twitched.
These guys with elephant trunks on their heads not only want to smash the door, they also want to smash the windows on the top of the ship. However, the windows of the ship pull the tough barbed wire from top to bottom, and the pebbles hit a dent in the network, and they snap.
Rolled onto the deck.
The Wei Keng consciousness group immediately cursed: "These finless porpoises are as annoying as the macaques in Mount Emei."
At this time, the system belatedly explained: "This is an aggressive finless porpoise, which has evolved stone-throwing skills. Although it is mainly based on the genes of the artiodactyl finless porpoise, the teeth are fused with shark genes and can proliferate indefinitely.
.This allows them to use their teeth to grind pebbles of about 500 grams, and use their nasal nozzles to spray projectiles for attack.
The projectile's jet speed can reach 33m/s. With its swimming speed, the projectile speed can often reach 50m/s.
This is simply the power of a small slinger. Moreover, they are used to knocking creatures on boats and shore into the water, and then eating them.
After encountering a surprise attack,
In Zhen Xinzheng’s eyes, the finless porpoise is not so cute. He commented in his heart: “A deformity with a weird nose.”
Then, he added cynically: "When the autumn wind blows on August 8, I will fry the fish in full bloom."
…
The finless porpoise that came to cause trouble circled the ship twice. Seeing that all the people were hiding in the cabin, they seemed very dissatisfied and tried to block the door and catch people.
However, a few minutes later, as the mechanical flying dragon roared from the sky and hovered above the river, these finless porpoises ran away like mice.
Zeng Lin raised his head and said: "The attack system, the river patrol osprey, is specially used to protect the safety of the waterway."
As soon as he finished speaking, a series of small bombs fell from the sky.
With a large amount of water splashing, bloodshot threads seemed to float on the river surface, but then they disappeared as the river surface rolled.
The electric shock mechanical beast that Zeng Lin was going to activate retracted into the container in the cabin.
…
Five minutes later, when the ship continued to sail down the river, Zhenxin saw a tall tower standing in the mist on the shore. There were many old-era cranes (steel cranes used to repair houses) around the tower.
The shadow in the sky, the same as the previous cruising Osprey, fell on the tower, grabbed the mechanical lever, and then rotated into the tower.
Since then, Wei Keng has had an intuitive understanding of the public system of the entire Yangtze River system.
Roads, river transportation, inns, patrols, and a series of public departments protect the transportation network. The governance capabilities of the city-states in the entire Yangtze River region are acceptable.
Wei Keng: "According to the information provided by the system, although it is still an aristocratic system, it is obviously much better than the fragmented small city-states in Guangdong."
However, in the following plot (explored in multiple timelines), such a system weakened after forty years, causing the death of millions of humans? It couldn't be a plot directed by Luo Hongxing's time traveler, right?
Bai Linglu personally gave the answer: "No, before you traveled for the first time, when this plane was still in an unknown and terrifying state, those dozens of explorers discovered during their exploration that there would be huge problems in human city-states.
The plot of decline. This great decline will even lead to the extinction of human forces in the Yangtze River Basin. After your arrival and the formation of human settlements in the Pearl District, the danger of extinction is gone, but the plot of the great decline cannot be changed."
Wei Keng: “What is the reason for the Great Decline?”
Bai Linglu: "Apostle!"
Wei Keng: “Apostle?”
Bai Linglu smiled mysteriously: "Roughly speaking, you will also be defined as an apostle."
