Tianxiang hadn't seen this thing, or even heard of it. It's just because he's lonely and unheard, but all the bugs he hunted before don't have any such thing as brains. Even if you open the hard lumps behind all the bugs' heads, all you get is a dull mass of various colored slurries. The biggest difference between the so-called evolutionary species is probably precisely because of this.

Tianxiang struggled, using the last bit of clarity in his brain to direct his exhausted body to move towards the insect corpse. Although the distance was only a few meters, he walked for nearly half a minute. Then, Tianxiang, who had successfully reached the front of the insect beast that had completely stiffened its head, grabbed the two pieces of hard armor fragments that had been shattered by the bullet with both hands, and suddenly stretched his head forward, and approached the two piles of fresh, still emitting a trace of hot insect and beast brains, and swallowed desperately.

"Delicious! It's delicious! Tianxiang, whose mouth was stuffed with snow-white and slippery slurry, swallowed a few large mouthfuls without chewing at all. He had never imagined that the terrifying-looking insect and beast brain pulp would be so delicious. Fresh, creamy, slightly sweet, full of taste. Even the tenderness that seems to be secreted by herbivorous insects like jelly cannot match the wonderful taste of the brain fluid of this insect beast. Tianxiang, who had drained all the white slurry in a few sips, felt that he had really lived in vain for so long before, and he didn't know that there was such a delicious thing in this world. Moreover, this insect beast has too little brain, and he only sucked a few puffs casually, and he has already swept away all the contents of the worm's skull. If you think about it carefully, the brains of this insect beast are probably just a fist-sized mass. Compared to its body that fell to the ground like a small building, it was too small.

Perhaps, this is why bugs are far less intelligent than humans!

After a few mouthfuls of steaming slurry, Tianxiang immediately felt the lost strength return to his body. Leaning slightly against the insect corpse and resting for a few minutes, he had regained some of his strength. Although the threat of thirst has not been completely removed, it is much better in terms of the situation just now. It's just that the only thing that Tianxiang regrets is that the amount of that delicious insect and beast brain is too small to let himself enjoy it at one time.

Suddenly, Tianxiang felt that his body seemed to have undergone a rather strange change. It was as if the ears could hear sounds from afar, and the eyes could see the subtle changes hidden in the cracks in the ground. The most important thing is my own thinking ability, many things that I couldn't understand before, but now I think through and through like a mirror. It was as if an invisible hand had torn off the thin veil that had shrouded in front of him, and the hazy state had been completely swept away, replaced by an unprecedented clarity and clarity.

In fact, the reason for this result was the brain of the insect beast that was shot and killed by Tianxiang. Generally speaking, in the process of evolution, the structure and function of the brain largely determine the evolutionary outcome of organisms. In particular, the brain and nervous system of these creatures that have just evolved from lower insects to higher classes will also become particularly developed. Insects' innate sensitivity to the outside world is also immediately reflected in the brain receptors at a rate that humans simply can't imagine. The so-called activity of brain cells refers to this aspect.

It should be said that Tianxiang's luck is not ordinarily good. He actually encountered an insect beast that had fully entered adulthood, and he drank all the brains of this insect beast by mistake. In a normal amount of time, the brain cells of the insect beast will die completely after the mother body is cut off from oxygen for more than a few minutes. However, during this time, although most of the worm brain swallowed by Tianxiang was killed by stomach acid, the remaining part of the cells also gained the ability to re-adapt to the new environment and survived. The most important thing is that because of the large amount of physical exertion before, as well as the sudden impact of the two major emotions of death threat and regaining life, Tianxiang's brain thinking ability also had a brief pause. However, in just a few seconds, the brain cells of the insect beast have a chance to temporarily dominate their functions. Although this domination was quickly completely eliminated by the autonomous consciousness in Tianxiang's brain, the ability to mimic and classify cells also allowed the defender itself to possess almost all the functions of the worm brain. As long as any of these conditions are missing, it is impossible for Tianxiang to bring such luck. Even if he could kill the same insect beast again and swallow its brain fluid in the same way now, he would never have a second chance to pause his brain. Such a delicate but reasonable circumstance may have been something that even the Almighty Creator had not foreseen in the process of the evolution of all living beings in advance.

Therefore, the current Tianxiang can be said to be a human with the powerful perception and thinking ability of insects and beasts.

Tianxiang, who didn't know that his body had changed so much in just a few minutes, was concentrating on carefully looking at the pistol in his hand that had saved his life at a critical moment. The things in the learning machine that I used to find difficult to understand are now as clear as the most transparent water. And the contents of the book of firearms that he discarded at random in the library were completely reflected in his mind after just one glance. There are also ears to hear the sound of insects crawling on the ground in the distance, as well as the slight vibration of the wings of flying insects cutting through the air, coupled with the contact between the brain's powerful perception ability and the surrounding environment, a large number of sudden inexplicable information, almost blocked by the brain of Tianxiang, who had just escaped from under the worm's mouth, to short circuit.

The human brain is born with the most powerful function of learning and self-exploitation, of course, such ability acquisition generally must rely on years of exercise and thinking to be formed. Just like when you pick up a heavy object with your left hand, it is natural to think of using your idle right hand to help it, and Tianxiang Brain, which is unable to receive a lot of information because of imitating the insect brain, has once again greatly improved its ability. To put it simply, Tianxiang's brain has completed a sudden and comprehensive evolution in a short period of time. The capacity of the cerebral cortex, which can store information and participate in thinking, has suddenly increased several times, giving it unprecedented power to think and perceive.

It's just that this kind of evolution, which is entirely part of the brain's self-awareness, is quite dangerous. Not to mention that the influx of a large amount of information is extremely high, which may make Tianxiang become a fool with a mess in his head on the spot, and even the cells in his body that have just suppressed the insect brain will die in large numbers because they can't accept both human and insect consciousness. As a result, the central nervous system under the control of the brain is completely paralyzed, causing the human body to lose all functions, and instantly changing from a healthy person who is alive and healthy to a "corpse" with only the brain alive. If it weren't for the fact that Tian Xiang changed the direction of his thinking quite accidentally at a critical moment, and attributed all the chaotic information to the command management of a clear thinking channel, I am afraid that he, an outlier among the survivors of the earth, would soon have to accept the terrible reality of a complete collapse of his central nervous system while just gaining superhuman abilities.

"Back in the library, there must be a lot of secrets I haven't discovered before." This was the only thought that suddenly flashed in Tianxiang's mind at that time. He couldn't tell why he had the idea for no apparent reason, but he felt that in that dilapidated library, there should be something he desperately wanted to obtain.

Tianxiang, who didn't have time to think about it, didn't know that he had just turned around again on the edge of the most terrible life and death, and pulled out the steel spear that had lost its luster from the eyes of the insects, and carefully wiped it clean with a rag hanging from the corner of his clothes, and then gently checked it and held it back in his hand. There were only four bullets in that pistol, and three of them had already been reimbursed for the random shot just now. If you don't have a weapon, I'm afraid that if you encounter a powerful bug again, you won't have such luck.

After inserting the steel spear, Tianxiang took out the short and delicate dagger from his waist and forcefully cut through the hard armor skin on the back surface of the corpse of the insect beast. Suddenly a piece of crystal clear pale red insect flesh was revealed. If it were in normal times, Tianxiang would definitely not let go of such a large pile of "Roshan". If this insect beast is dried and dried, it will at least be enough for him and his sister to eat ten sun days. It's just that now he can only cut off a piece of his arm from it. After all, this is not a crypt, and taking too many things will only cause more trouble for yourself. Just take the part that is enough to eat yourself, and as for the leftovers, it is best to save them for other weak creatures.

Tianxiang, who returned the same way, did not alarm the other insects that were entrenched in the library, and still quietly touched the second floor according to the previous route. He was here to figure out all there was to know about the "gun", to figure out why this seemingly inconspicuous weapon was so powerful. Of course, he didn't let go of any slight anomalies in entering the library. It wasn't because he was on the lookout for bugs, but he wanted to try his luck and get his hands on a gun and more bullets. But to his disappointment, there were many bones of ancient people scattered in the museum, but there was no longer a situation where he held a gun in his hand as before.

It's still the pile of military books, and Tianxiang, who had just stepped up the stairs, saw the firearm atlas that he had thrown away. Suddenly, like the most precious treasure, he carefully picked it up from the pile of old papers and carefully flipped through it.

One, two。。。。。。 One pile, two piles。。。。。。 Tianxiang was surprised to find that his reading speed was so fast, it was simply astonishingly fast. Before he knew it, he had finished reading several thick piles of books in front of him, including the firearms atlas. A page covered in tiny black letters can be memorized in just a few seconds of browsing. The quick flipping through the motion made him feel a little scrambling. This kind of thing was impossible before!

Is this a useful view? Can I remember what I watched? Tianxiang began to doubt his speed of reading ten lines and hundreds of lines at a glance, and couldn't help but gently close a book in his hand that he was reading happily, close his eyes, and carefully recall the contents of the books that he had just read.

"Oh my God! How is this possible? As a result of the short thought, even Tianxiang himself was taken aback. Not only was the content of the book completely memorized by him word for word, but even some of the things he had never been exposed to before, and the sentences were jerky and difficult to understand. It's just that he can understand some of the knowledge recorded in these books, but he doesn't understand how to use it at all. Or rather, he simply didn't know what this knowledge was for.

For example, in a book called "Introduction to Infantry Tactics", the method of using a so-called "army" is clearly proposed. What words and knowledge such as "correct defense in battle", "offense", and "tactical theory", Tianxiang completely kept in mind. I believe that at this time, even if he is given the most difficult test paper in this area, he can easily answer the correct answer. However, Tianxiang, who received 100 points as a result, could not make a reasonable explanation for what "infantry" and "army" were at all, and what the specific role of these things would be.

This situation is completely like a person who has a large amount of money in his hand, but when he is extremely hungry, he has no idea that he can use it to exchange it for the most delicious food to fill his stomach.

Undoubtedly, there is no point in reading such a book, and it will not be a little fun at all. Except for some articles explaining pistols in the firearms atlas, Tianxiang's newly evolved brain can only act as a knowledge loader for the time being. After all, although the pistol is also a new thing for him, no matter what, he has shot a gun after all, and he also has a ready-made physical object. It will certainly be easy to understand.

As for other knowledge, just read it and keep it for later! After all, the books here have been eroded for too long, and anything outside of them can be reduced to crumbles. Rather than being ruined so casually, it is better to read it yourself and remember it.

Not all books look boring, and some books Tianxiang will find it interesting. He couldn't figure out how those ancients could have so much knowledge and how they could make up so many wonderful stories. From these moldy and rotten books, Tianxiang comes into contact with a world that he had never thought of before. The sky is blue, the trees are green, and the world is colorful and splendid. Even the sun, which everyone regarded as the most precious treasure, only quietly hid for a few hours at night, then radiated its beautiful and dazzling light again.

Is the world of the ancients really that wonderful? So, what is it that has made their world what it is now?

Tianxiang didn't get the answers he wanted in the book. Truth be told, he would love to live here forever and read every book here. But no. It's been too long since I've been out on my own. Although my sister who stayed alone in the crypt would not be afraid of being alone, there was not much food left for her. At normal consumption, you'll only need a little more than two solar days at most, oh! No, it should be about ten days, and everything in the crypt will be eaten up. This is the answer that Tianxiang has come up with based on his own experience and the knowledge gained from the book. According to those ancients, there were twenty-four hours in a day. And now a solar day is exactly a hundred hours, which is exactly more than four days and one day.

"Three days, three more days, and then I have to go back." Tianxiang told himself that the speed of flipping through the books in his hands did not stop at all. As for hunger and thirst, the water bag and the fresh worm meat found on the way back to the library were enough to feed myself for a few days. Sometimes, raw meat tastes quite good when chewed.

When you focus on one thing, time flies quickly, which is an experience that many people have. The same goes for Tianxiang. Before he knew it, he had rummaged through nearly half of the books on the second floor of the library. And two full days have passed.

Like the lobby on the first floor, the second floor is also littered with the remains of ancient people. Whenever he found these gray-white bones hidden by dust and confetti, Tianxiang would always search up and down carefully. Although it took a lot of time, he still didn't give up. He wanted to see if he could find more "guns" and "bullets" from them. You know, with the help of these ancient weapons, your own security will naturally increase a little. However, as in the case on the first floor, the hopeful Tianxiang never found what he was looking for.

However, such searches are not entirely fruitless. While rummaging through a relatively neatly dressed skeletal suit, Tianxiang stumbled upon something that interested him.

"The Key to the Curator's Room", a string of metal objects placed in the skull's intimate coat pocket and pinned to the inner edge with a small buckle. The text engraved in the groove above explains what it was actually used for.
