These unknown creatures surround the bottom of the mountain, but they refuse to leave, and kept going back and forth around the bottom of the mountain.

Chen Jian would not miss the opportunity to observe this unknown creature at such a close distance. He looked up and did not continue to climb up, but looked down at these unknown creatures.

No. 2 also looked up at the top of the mountain and said, "This mountain is no more than a hundred meters high!"

The location of Chen Jian and No. 2 at this time is only a few dozen meters high, at most no more than fifty meters. Looking up, the top of the mountain can be seen, and it is only a little higher than the height they are currently at, and it is not a very high mountain.

A mountain with a height of 100 meters is nothing in the outside world. It can be said that it has no height. However, at this time, it is in the underground space, and it is very shocking to have such a mountain with a height of nearly 100 meters.

Chen Jian looked at the unknown creatures going around in circles below and said, "They cooperated very well when attacking!"

Although No. 2 only looked back, he could imagine what the situation was, because when she looked back, several unknown creatures happened to attack a creature like the test subject. No. 2 naturally saw the unknown creature attacking, how tacit cooperation was.

"They are sociable animals." Chen Jian said at this time again.

No. 2 nodded. These unknown creatures showed the characteristics of sociable animals.

"Do you feel that they look a bit like any animal?" Chen Jian asked with a smile.

Number Two shook her head and said, "Nothing special."

"Any group of animals must have a leader." Chen Jian smiled and pointed to one of them, saying, "That end is their leader!"

Although the unknown creature Chen Jian was referring to was not the largest, it could be seen that its status was somewhat outstanding, because it did not go around the ground like other creatures in the position, but instead squatted on the ground and looked up at Chen Jian and No. 2.

"Did you find something?" No. 2 asked suspiciously.

Chen Jian nodded and said, "When I saw that when they were attacking, the leader was attacked by them. Although it was not a very fierce attack, it just hit it a few times, but this is very telling!"

He specializes in the arts. No. 2 is very skilled in dismantling the device for directional blasting first and then assembling it, but she doesn't know what Chen Jian said.

No. 2 looked at Chen Jian curiously, obviously waiting for Chen Jian to explain to her.

"Two million years ago, there were three top killers in the food chain on Earth. According to their power, from large to small, namely Titan, Sabertoothed Tiger and Wolf." Chen Jian said: "So far, only wolves have survived. The wolf pack's favorite is team combat. They have extremely fierce attack methods, and their teeth bite far exceeds that of Siberian tigers. As time goes by, other top killers have disappeared, and wolves have once become the highest overlord of the food chain."

No. 2 nodded silently, knowing that the wolf is a herd animal.

However, what No. 2 didn't know was that the wolf was once at the top of the food chain!

"About a million years later, this status began to be replaced by humans who are better at group cooperation." Chen Jian continued: "But the wolf pack still exists!"

After a pause, Chen Jian continued: "Everyone who survived and who once stood at the top of the food chain must have something unique. In other words, the wolf pack has its uniqueness, so it can continue to this day!"

No. 2 knew that Chen Jian was going to focus on the key points and asked: "Does the characteristics you mentioned have the scene you just saw?"

"Wolves are particularly principled. To give a simple example, a wolf follows only one partner in his life. Even the wolf king must abide by this regulation and cannot arbitrarily occupy other wolf companions." Chen Jian nodded and said, "It can be seen that the rules of the wolf pack are particularly strict and ruthless. No matter who makes a mistake, they will be attacked by the wolf pack, and the mouth is very heavy. If the wolf king makes a mistake, he will be attacked by the wolf pack directly. The scene is quite tragic."

After a pause, Chen Jian pointed to the leader of the unknown creature he had pointed to before and said, "It is like a wolf king. It was attacked before, but it was not a very serious attack. It is because it made a mistake. This characteristic is only available to wolves, but other social animals do not."

"What mistake did it make?" No. 2 asked in confusion.

Chen Jian smiled and said, "The attack of the wolf pack is to obey the wolf king. This group of unknown creatures also has this characteristic. When the attack began, it was the attack order it issued. However, those creatures like the test subjects were suppressed by me and issued the order to attack them. The leader of this unknown creature did not issue the attack order as soon as possible, resulting in chaos. Their group died, and several unknown creatures were directly bitten to death. This is the mistake it made!"

"Didn't that mean that if it hasn't reacted and does not issue an attack order, it is very likely that it will be directly attacked and killed by other unknown creatures?" No. 2 asked in surprise.

Chen Jian shook his head slowly and said, "It's impossible to be sure, because what you are talking about is a hypothesis. We have never seen this unknown creature. At present, we just compare them with known animals and infer that they are similar to wolves!"

"There are only two situations. Their group characteristics, the same as the group characteristics of wolves, will definitely happen." No. 2 immediately said: "If it is just the group characteristics similar, not exactly the same, the situation I mentioned may not necessarily happen."

Chen Jian nodded and said, "It's probably that."

No. 2 then said: "If their group characteristics are exactly the same as those of wolves, is it possible that they will be wolves before they are infected?"

Chen Jian frowned and said, "This is exactly what I am confused about, because at that secret research center, animals had been tested and found that this virus could not cause infection to animals, or after the animal was infected, it would be impossible to have a test sample!"

"Is that true?" No. 2 frowned in confusion when he heard Chen Jian's words and asked casually: "Where did the virus in the research center come from?"

Hearing the question of No. 2, a light flashed through Chen Jian's mind, but this light flashed away. Chen Jian frowned in confusion, waved his hand, and signaled No. 2 not to speak again.
