Changfeng felt that there was something strange about these stones. Under the spells and handprints, he took a deep breath and felt that the sound was broken by his own magic power. He turned his right hand into a palm and drew a barrier talisman in the air.
At the end of the article, he waved his pen vigorously and shouted: "Three Pure Realms Formation, Imperial Order!"
The Sanqing runes formed in the air immediately turned into a barrier and fell around the seven people, becoming a protective barrier. In the blink of an eye, the rolling stones had already rolled onto their heads and fell on the barrier.
When they reached the outer edge of the boundary, the stones disappeared one by one, but the momentum of the rolling stones did not diminish at all.
"Illusion!" Changfeng finally confirmed that the stones were not real, but the sound caused people to hallucinate and create an illusion.
"Tingting, the Divine Weapon Order!" Changfeng shouted to Wang Tingting. Wang Tingting was shocked and immediately joined him in making seals with her hands.
"The magic weapon is urgent, the urgency is like the law!" The two of them said in unison, and through their commands and gestures, they formed the magic weapon formula. After they said "break" out of the formula, two blue lights and shadows,
It shot out from their fingertips and directly into the illusion. After hearing the crackling sound, everything returned to purity.
Everyone felt relaxed and looked around in astonishment. The rolling stones that had just rolled around had all disappeared without a trace.
Ye Qingcheng, who was on the side, looked at Wang Tingting and Changfeng in shock, and was speechless for a long time. Because the behavior of these two people just now was beyond her knowledge.
She can accept people with special powers, but the behavior of these two people just now cannot be compared with people with special powers. It's not like Ye Qingcheng has never seen movies. The behavior of Taoist priests and mages in them is different from the two people in front of her.
, they are basically the same type of people.
Changfeng ignored Ye Qingcheng's shock and said to everyone: "Be careful, everyone, the sound just made us hallucinate, we must leave as soon as possible." Seeing Wang Tingting thinking deeply about something, Changfeng asked in a low voice: "What's wrong with you?"
"I'm wondering, is this hallucination really caused by the sound?" Wang Tingting raised her head and looked at Changfeng. If it was caused by the sound, then the Yin Qi was too strong in the sixth area and the sound hadn't sounded yet. She
I have already seen the flashing black shadow. If the black shadow is also caused by an illusion, then it proves that it has nothing to do with the sound. If it is not caused by an hallucination, then what is the black shadow? What does it have to do with following the sound?
Wang Tingting's question made Changfeng understand. He suddenly became nervous and said: "Oops!"
His two words attracted everyone's attention. Looking at their eyes, he said slowly: "If my guess is correct... we have been poisoned!"
"Poisoned?"
"That's right, poisoning!" Changfeng glanced at everyone and said, "The mucus on those bats!"
"Impossible, we have never touched the mucus on the bat wings, how could it be poisoned?"
"You don't have to encounter poisoning!" Changfeng continued: "Those mucus can make people hallucinate, so will the mucus evaporate?"
"If these mucus will evaporate, and everyone who enters this underground ancient city will inhale it into their bodies, then there will be more or less signs of poisoning!" Wang Tingting shook her head and said, "If this is the case, everyone who enters this ancient city will
, will be poisoned, we have been here for so long, and we don’t feel anything at all.”
"That's because we didn't encounter a group of bats when we came in! The group of bats just flew over our heads, and there may be their residual toxins in the air." Changfeng's words are reasonable. If the mucus can evaporate, then the group of bats will
Wherever it flies, the air flow it brings contains the volatile toxins.
Ye Qingcheng was beating a drum in his heart. He took out a miniature mask from his backpack and put it on himself. Wang Tingting saw it and said: "Miss Ye, it's too late to put it on now!"
"It would be nice to inhale less. If this toxin enters the body, I don't know if it will affect the face! I don't want to take this risk!" After saying that, she put on her night vision goggles and strode forward.
The mucus of bats can cause hallucinations in people, and once the sound reaches a certain level, it can also cause hallucinations. These two ways of affecting human nerves appear in this place at the same time, which makes Changfeng feel very heavy.
When we got to the big rocks, everyone felt relieved. We no longer had to worry about the big rocks rolling down. After glancing at the big rocks, we saw that they were typical falling rocks on ancient battlefields. The nearby rocks were large and small, like millstones.
Because of the age and changes in the earth's crust, only part of the prepared stones is exposed.
This rockfall area can accommodate more than twenty people sitting loosely on it. There are some rotten transport vehicles scattered around. Nearby, you can also see some incomprehensible symbols carved on some stones.
Changfeng glanced at the rotting transport trucks nearby and the dilapidated equipment next to the big rocks that immediately aroused his interest, and he walked over in surprise.
"Changfeng, what's so surprising about these crappy things?" Wang Tingting asked in confusion.
"Come and see, what is this?" Changfeng pointed to a trebuchet-like device. This device was made of metal and wooden strips, and was wrapped in cowhide, oilcloth, etc.
Wang Tingting shook her head and wondered. She had not studied ancient weapons carefully, so she could not tell them clearly. However, Changfeng was very familiar with them because he had extraordinary achievements in archeology and could tell the difference at a glance.
"Look, this should be a trebuchet. Yes, it's really a trebuchet!" Changfeng looked very excited. He wished he could take this thing out, but accidentally, he pinched a piece of wood from the trebuchet.
It broke, which made him very distressed.
China's trebuchets first appeared in the Warring States Period. Manpower was used to pull the tips (gun tips) connected to the crossbar away from the trebuchet, which were placed on a wooden frame. One end was tied with a rope to hold the holster containing the stone bullets.
The other end is tied with many ropes to facilitate manual pulling) to throw the stone bullets, which are divided into single-shot and multi-shot. The most has thirteen shots, and a maximum of 500 people are required to cast it.
Before the Song Dynasty, trebuchets were mainly fired by manpower or animal power. That is, a large number of soldiers or horses suddenly pulled the pulling rope in one direction at the same time, pulling up the arm to launch the heavy cannon stone in a parabola.
Subsequently, the Mongolian army developed the trebuchet to be extremely sharp and terrifying due to world wars. The Mongols designed a compound bow structure with double crossbow backs, which has stronger elasticity. At the same time, such crossbows are sometimes used to launch special iron arrows and
Fuel cylinders, and even later, the Mongols used trebuchets to project rotten human and animal corpses as the most primitive "biological weapons."
The invention and innovation of the trebuchet, the most advanced, most powerful, and most innovative in the entire history of human warfare, belongs to China.
Changfeng was very excited when he saw this trebuchet, because this trebuchet could be easily used by a single person, had crude aiming equipment, and could be launched through gears using the lever principle.
This technology was too advanced for the time!
Changfeng's explanation immediately attracted the two girls, Ye Qingcheng and Wang Tingting. They took out their camera equipment and immediately took pictures and recorded them. Even Ren Tianxing was attracted.
What surprised them even more was that the big stone weighed at least 10 tons. If they wanted to push the stone down, it would take many people to push it. But looking at the ground of the stone, there was a layer covered with patina.
The metal clip looks like this. At that time, the metal clip should have had a switch. As soon as the switch was turned on, the stone would roll down.
At the bottom of the stone, there are two metal rods that are parallel to each other and extend far behind. The two metal rods are like modern railroad tracks. So, the only way to explain it is that the people in this ancient city should have
With technology similar to rail transport vehicles.
Some experts believe that this ancient city was established as early as 3,000 years ago. If this expert’s guess is correct, does it mean that 3,000 years ago, humans already had such technological knowledge?
3000 years ago, human technology had developed to the level of metal forging, rail use, gears and levers?
"My God!" Moss, who seldom spoke, exclaimed after hearing this and said amen to him.
"Oh my god, Brother Changfeng, do you think these things were left by the Mayans?" Ye Qingcheng was very shocked. In her impression, the Mayans were the only ones with such technology. Her guess won the favor of everyone.
recognition.
It was very close from here to the exit leading to the abandoned mine. Although they were interested in these things, they didn't waste much time. Anyway, there was only a long way to go.
"Changfeng, look!" Ren Tianxing glanced around unintentionally and discovered a strange terrain. Changfeng looked in the direction Ren Tianxing pointed. The exit direction was like a trumpet. The center of the trumpet was exactly
It's a big round hole at the exit.
Changfeng stared blankly at the exit, then ran forward. Wang Tingting followed immediately, and after the others looked at each other, they also followed Changfeng, and everyone started trotting.
When Changfeng ran to the exit, he saw that the exit was like a cave. He found a fist-sized stone and threw it towards the stone wall outside the cave entrance. The stone hit the stone wall, flashing a few sparks, and then made a crashing sound.
The sound, this sound was very loud, which surprised everyone.
"So loud? Is the resonance of the sound so loud?" Wang Tingting took a look in surprise and picked up a stone and threw it over. At this time, after the sound of the stone hit, it made a very miserable cry. When everyone saw the stone,
Just like hitting a person, a black shadow like a face was crawling on the stone wall, as if there was hell behind the stone wall. The devil was locked inside, and only the terrifying outline could be seen. This situation made everyone's hair stand on end.
I felt a chill on my back, my scalp was numb, and my whole body shivered unnaturally.
