"Sir, I'll do it." Ruan Ling said. Lan Yunxi hesitated for a moment and did not argue with Ruan Ling. She is Liuyun's leader. She is good at grabbing things. It's so troublesome to buy things. When she arrives at someone's territory, she may have to be angry and dangerous.

Ruan Ling is different. Before she joined the Shengong Hall, she was one of the business members established by Yulin City and was very experienced in doing business.

In order to get enough silk, Renault gave Ruan Ling a lot of power. In addition to transferring all ten hot air balloons to her, he also gave her two hundred black-haired flying cavalry. As long as she brought it up, Renault would meet the supplies in the convoy unconditionally.

Ruan Ling knows much more than Renault. She brought 10,000 gold coins and five boxes of life-saving pills, which would be enough to exchange for fifteen tons of silk. If it were not limited by transportation capacity, the wealth in Renault's fleet would be able to buy silk far beyond imagination.

Mo Qiang was also left with Ruan Ling, and there was no grandmaster in charge, so Renault was worried.

After Ruan Ling started, Renault began to take stock of the team's gains these days. Zhang Tan worked very hard and added fifty muskets. Hearing this data, Renault shook his head. The production efficiency was too low. The number of barrels was quite large, but the springs were unable to increase the output. On average, there were only two qualified springs a day. It seemed that Renault had to take action himself.

The increase in the number of muskets made Renault angry, but the research on artillery was delighted. In less than a month, Zhangtan not only completed the design, research and development, test firing experiments, and finalization, but also completed the process flow, and waited for Renault to make the decision and then mass production could be directly produced.

After studying the production of muskets, Renault is much easier to use. In fact, what Renault wants is not a real gun, but more like an enlarged version of a gun lift. It fires not a solid iron ball or a relatively advanced flowering bullet. Renault can't do the trick of flowering bullets for the time being.

The artillery that Renault wants is as long as it can fire a scoop. Even the range requirements are very low, at least 100 steps, and it would be even better if it can reach 200 steps.

After trying ten guns in a row, Renault was quite satisfied. The artillery independently developed by Zhangtan can penetrate a single-layer leather armor within 150 steps. This kind of lethality is enough. The gun barrel is filled with shotguns. Each shotgun has a specially made triangular iron spike, which has much higher lethality than iron sand. Anyway, as long as this kind of iron spike is modeled, it can be cast directly, and there is no requirement for strength and quality.

In a shotgun, there are a total of 100 such iron spikes, with a total weight of three pounds and two ounces. Mixed in seven and a half pounds of gunpowder, the effect is very good. Within the effective range, a group of cows can be knocked down.

There are two problems with this kind of artillery that cannot be solved. One is that the firing rate is very slow. There is nothing to say about the first artillery. You can prepare in advance. Starting from the second artillery, you need to clean the chamber with clean water and reduce the temperature at the same time. Then wipe it with a dry cloth and fill the fixed-load shells with mixed iron spikes. Finally, you must compact it and release the gunpowder before it can be fired.

The second problem is that the material of the gun barrel will not explode, but the seven and a half kilograms of black gunpowder will generate a lot of heat when fired. The heat dissipation speed of the gun barrel is much slower than the launch speed. After firing ten guns in a row, you must stop and wait for the cooling down, otherwise you don’t need to ignite the fuse and the newly loaded bullet will explode by itself.

Renault had no good idea about the barrel problem. The previous one reminded him of a piece of history: "Zhangtan, try to make a batch of mother and child tubes."

As he said that, he took a piece of paper and drew it. The mother-child tube was a bit like a shell shell. He made a cob that was slightly thinner than the barrel. He loaded the ammunition in advance. During the battle, he stuffed the cob into the barrel chamber. After firing, he hooked the cob out and changed it to another one and continued firing.

A cannon can be equipped with three to five cylinders, so that the firing speed can be increased by five to ten times.

Zhang Tan understood it as soon as he heard it. This method is good and not difficult.

In fact, Renault has a good idea in his mind, but due to Dachu's materials and production capacity, he can only use the stupidest solution.

Except for artillery and grenades, Zhangtan did not ask for instructions and started production directly. Due to insufficient materials, he did not dare to make more, and only made five thousand pieces.

When the convoy came out of Dingjun City, it was full of loads, not only food, cloth, but also iron. Renault had many requirements. How much iron can the convoy bring? Now there is not much left. Zhangtan tried to use it to produce muskets and springs. Preparing 5,000 consumables like grenades is the limit.

In a blink of an eye, the convoy walked in the rain forest for more than two months, and in another two months, he could reach the forbidden area of ​​death chosen by Reno.

In the past two months, Renault missed the seven days of driving the hot air balloon. In the dark rain forest, over time, he was about to collapse, and Renault could not bear it anymore.

In order to solve everyone's psychological problems, the people in the convoy took turns to ride in black hair and circled around the sky to relieve their depression.

Of course, there was good news. After forty days, Ruan Ling finally brought back fifteen tons of silk. After hearing what she said, Renault learned from Baiqiang that the business was very thrilling.

He was guilty of being guilty of being in trouble. He brought money that could buy fifteen tons of silk. Many people were jealous. Ruan Ling was fighting wits and courage with major trading companies in Shunde Prefecture. If Bai Qiang had not fought to protect her, she would have died dozens of times long ago.

Although there are not many masters in Da Chu, there are still big cities like Shunde Prefecture. Those who can afford silk business are all big businesses, and it is impossible to support the master. If you spend a sky-high price, there is no problem at all.

It was not until they discovered that Ruan Ling had a master around him that they had to give up using force and gave up the idea of ​​robbing for force.

Ruan Ling's trip took ten more days than Renault expected. Not only was the driver not skilled enough in operation, but Song Zhe was not instructed, but it was because Ruan Ling tried to avoid other people's sight. Until the business was completed, few people had seen hot air balloons.

This made Renault quite satisfied. Sooner or later, strategic equipment such as hot air balloons will make people know that the Shengong Temple now does not even have a camp, so naturally the later it is exposed, the better.

This is in the Nanzhang area, where rainforests are everywhere, and you can’t see the sun when you look up. In addition, the land is vast and sparsely populated. As long as the landing location is farther from Shunde Prefecture, you can barely do it. If you are in the inner land of Da Chu, even if you only fly at night, it will be extremely difficult to avoid being discovered.

The arduous rainforest road finally arrived at its destination after two and a half months, a piece of desolate land.

In the Nanzhang area, it is quite difficult to find a place without rainforests, but no one dares to live in this wasteland of nearly 100,000 square kilometers. It is close to the rainforest, and the other is to the forbidden land of the Death God who has changed color by the people of Nanzhang, and the other is to the sea.

It is said that this is a place where the god of death is cursed. No matter which toast is, as long as you move here to live, the whole clan will die soon, without exception. As for the various creepy beast roars at night, losing a few people from time to time, it can only be considered a trivial matter.

Here, it is just the periphery of the Forbidden Land of Death. Crossing this desolate red land, it is a mountain range with a wide range, and there is the real Forbidden Land of Death.

No one knows what is in the mountains. It is not difficult to walk through this desolate land alive. In the mountains, very few people can survive a night. Occasionally, there are people who escape alive, either silent or scared to death.

Reno can be said to be the only person in the world who knows what the Forbidden Land of Death is. Originally, he thought that it was just a mountain range. It was not until he walked here and activated the microorganisms that he truly saw the scene in the Forbidden Land of Death.

The Forbidden Land of Death is a super large volcano or crater with a diameter of more than 800 kilometers and a bottomless depth. The accumulated rocks on the periphery form the Death Mountains. The diameter is more than 1,500 kilometers, measured from the edge of both sides.

Not to mention the Death Mountains, just the desolate land that the convoy just stepped on, there is an underground world with an area larger than the surface. This underground world is the largest underground world that the God of Wealth has scanned so far, no doubt about it.

Even though Renault was already walking on this land at this time and stimulated the microorganisms to the maximum, the God of Wealth still could not scan the entire picture of the underground world.

At this time, Renault looked calm, but the corners of his mouth kept twitching. This is a treasure land.

Why are there no rainforest plants in this land of 100,000 square kilometers?

The reason is very simple. This is a mining area. Just under Renault's feet, he is stepping on a rich iron ore. The average iron content reaches 70%. It can be said that the convoy was walking on a huge iron ingot at this time.

In addition to iron ore, dozens of metal ore were found within the 300-meter depth scanned by the God of Wealth, among which as many as sixteen new unknown metal ores were added, and these metal ores were not available on the earth.

In the underground world, there are not only more types of metal minerals, but also many biotas with the same number and variety. The God of Wealth is still scanning and analyzing wildly. Before getting the scan analysis report, Renault did not know what these creatures rely on to form the biological chain.

There are more minerals in the underground world, which means that plants are also incapable of growing. Without plants, where do these animals come from?

The convoy did not go deep into the desolate land and marched towards the sea along the junction of the desolate land and the rainforest. The camp chosen by Reno not only had to be by the sea but also had enough water sources.

Although there is never a shortage of water in the rainforest, there are no rivers nearby. If you want to form a settlement for humans, it is absolutely impossible to have no rivers and lakes.

If there is no on the ground, it does not mean that there is no underground world. The Great Chu world is a world with very abundant water resources. With underdeveloped technology, the damage to nature will be very small.

Everyone had already smelled the slight sea breeze, and Renault finally gave the order to stop moving forward. This is a very magical place.

On the surface, this place is not suitable for building a city at all, and no leader will choose this place, but here is the outer periphery of the Forbidden Land of Death, and the most suitable place for building a city.
