He Weimin pointed to the metal cage in the experimental hall, and analyzed: "From the dozen or so monsters you caught, I have initially seen the group differences, there are generally three kinds of monsters, the first one with a darker color is the most fierce, I temporarily call it the first generation monster, the second color is a little lighter, and the strength is slightly inferior, call it the second-generation monster, and the third is the lightest in color and the worst in strength, called the third-generation monster." ”

Chen Fan responded: "Lao He, this is just a superficial difference, we still haven't found the weakness of the monster." ”

He Weimin nodded and said, "Yes, no matter what kind of monsters are of that generation, we must find their weaknesses and kill them." ”

Chen Fan proposed: "Let's start then! This time, we don't need to try too many weapons, just use a knife and see if the part that stabs the monster can kill it." ”

"Cheng, just try it as you say!"

Under the guidance of He Weimin, Chen Fan used a machine to tie the three monsters to a metal frame, and then started the experiment with a steel knife.

The first test subject was a third-generation monster, and in the face of Chen Fan, the monster was extremely irritable, constantly struggling, and shaking the metal frame to a clattering sound.

Chen Fan's face was like water, and he waved a steel knife and made a quick move.

A knife pierced the monster's heart, and the monster let out a terrible scream, and after a while, a pungent fishy smell diffused from the monster's wound.

It stands to reason that the heart is used for blood supply, and basically all living beings will not survive if their hearts are stabbed.

But the monster was different, it was stabbed in the heart, but it still lived well, and the mucus secreted by it healed the wound after a while.

Chen Fan stabbed the monster in the abdomen, head and other positions respectively, but the result was the same, the monster was still fine.

The three monsters are all the same, the only difference is that the healing ability of the first generation is relatively strong, and the healing ability of the third generation is a little worse.

Chen Fan was worried, and He Weimin was also worried.

Why can't monsters be killed?

"Lao He, do you have any other good proposals?"

He Weimin shook his head and said sadly: "I have also seen a lot of mutated fierce beasts and beasts, and it is really the first time I have encountered such a difficult monster, Chen Fan, let's rest first, eat something and then think of a way." ”

Chen Fan got up silently, and suddenly remembered the notebook left by Chen Kang, I don't know if there will be clues in it?

Just do it, Chen Fan flipped out his notebook and flipped through it while eating.

He Weimin saw that Chen Fan was watching so seriously, and he didn't bother, leaving space and time for Chen Fan to explore.

Chen Fan looked through the notebook left by his father, as if he had opened the perspective of God and looked at his father's past life from a different perspective.

Chen Fan is looking for clues in one stroke at a time, and from time to time he receives some small surprises.

It can be seen that Chen Kang has a lot of experience, and he has recorded the footprints of many species, including a species that is slightly similar to a monster.

According to the description in the notebook, the monster found by Chen Kang was not the same as the monster today.

At least it's not as ugly and disgusting as today's four monsters, and the twisted humanoid facial features don't exist.

The monster mentioned in the note is called a long-handed monster, with short legs and long hands, no obvious facial features, an eye like a fist on the top of the head, fast speed, and both hands can shoot air slashes.

Some of these traits are almost identical to those of the Four.

Chen Fan thought about it, could it be understood that the four monsters were strangely transformed from long hands.

Of course, the process of mutation must have happened in an indescribable way, and only then did the four different monsters appear.

Chen Fan then looked down, the long-handed monster was found by Chen Kang near the Valley of the Divine Tree, the long-handed monster was bathing in a pool full of slime in the Valley of the Divine Tree, and after being discovered by Chen Kang, he also fought with Chen Kang.

The long-handed monster is very ferocious, but Chen Kang is a holy warrior after all, and it is not a problem to suppress the long-handed monster, and in the process of fighting, Chen Kang also found that the long-handed monster has the ability to repair itself after being injured, but it is not that it cannot be killed.

As long as you stab the eyeball on the top of the long-handed monster's head, the long-handed monster will not be able to secrete mucus and lose the protection of the slime, so the long-handed monster is not a cause for concern.

After Chen Fan saw this, he stood up excitedly, wondering if the four monsters could also deal with it like this.

"Lao He, Lao He, I have found a clue!" Chen Fan stood up and shouted.

He Weimin smiled, in fact, he had also looked through Chen Kang's notes back then, and he also knew about the record of the long-handed monster, but he just didn't want to mention it.

The purpose was to stimulate Chen Fan's curiosity, because he knew that Chen Kang's notebook hid a very important secret, and the most important clues of the Holy Light Project back then should also be in the notebook.

It's a pity that He Weimin lacks comprehension and can't find this clue, he hopes that Chen Fan can crack it.

Only Chen Fan can break it, father and son are connected, Chen Fan has the same blood as Chen Kang flowing on his body, and the only person who can find the answer in the end is Chen Fan.

He Weimin pretended to be surprised: "Really, tell me what the clues are." ”

"There's a monster called the Long-Hand Monster in the notebook.,I think it's the predecessor of the four-like monster.,The weakness of the long-handed monster is the eyeball on the top of the head.,As long as you puncture the eyeball.,It can't secrete mucus.,It can kill to death.。 ”

He Weimin nodded and said, "So, you can kill the four monsters by piercing the eyeballs of the four monsters with a knife?"

"Try it!" Chen Fan said.

Standing in front of the monster again with a steel knife in his hand, Chen Fan's momentum was even stronger, and the monster was still irritable, howling at Chen Fan non-stop.

Chen Fan calmly stretched out his hand and grabbed the monster's head fiercely, aiming the tip of the knife at the monster's eyes, the monster began to panic, and kept struggling.

As the eyeball was punctured, silvery-white mucus gushed out of the wound.

After about ten seconds, the monster no longer secreted mucus, and Chen Fan decisively stabbed the monster in the chest again.

"Whew... The monster struggled and roared, and its hands and feet shook violently, clearly mortally wounded.

Chen Fan pulled out the steel knife violently, and a dark blue blood arrow gushed out from the monster's wound.

In less than half a minute, the third generation monster's head hung to the ground, and it was already dead.

Chen Fan said excitedly: "Lao He, is it really possible? The monster's weakness is the eyes." ”

He Weimin also puffed up his energy and said: "Chen Fan, you continue the experiment, I want to record the process." ”

"Good!"

Chen Fan concocted the same method and killed the second generation monster and the first generation monster in the same way, the difference is that it took longer to kill the first generation monster than the second and third generations.

But it doesn't matter, in the end the first monster is still dead.

He Weimin kept writing on the paper with a pen, and from time to time asked Chen Fan to flip the corpses of the three monsters to observe whether they were dead.
