Xiang Kun originally thought that the owl's variation direction should mostly rely on animal instinct and original habits, instead of deliberately training and guiding him.

But not far from the owl's nest on the cliff, a rock with claw marks beside a stream in the forest made Xiang Kun realize that the owl was actually carrying out targeted training.

Xiang Kun doesn't see it grinding its claws in the owl's memory picture, but according to the distance between the claws left on the rock, it is determined that these claw marks are left by the giant owl.

Judging from the traces on the rock, it was not only grinding its claws, but also attacked by a large number of claws, thorns and jujubes. At the beginning, the traces of claws "chiseling" were very shallow, while in the later stage, they became deeper and deeper. It was obvious that the stone was being attacked as an imaginary prey. Xiang Kun could also imagine that at the beginning, its claws must be scarred and often broken However, it has the ability to recover and lay the foundation, which has no effect on the survival. After the variation of drinking blood, the sharpness and hardness of claws will certainly be greatly improved.

The giant owl's huge and sharp claws are the result of the mutation and reinforcement.

After discovering the owl's training method, Xiang Kun also had an idea. Could he imitate the owl and sharpen his nails? If he had a sharp claw before, he would not need any weapons. If he took a black tiger's heart out in front of the huge owl, he would have great lethality

But almost immediately he gave up the idea. After all, bird's claws are not the same as human's hands. The main function of human hands is to use tools. If you can mutate ten "iron claws" that can stretch freely, if you directly mutate the nails into sharp claws like beasts, or they are hard and long, it is not only easy to attract people's attention, but also inconvenient to do things on weekdays, and it is easy to get stuck by typing the keyboard.

Xiang Kun also found a pile of small stones in the cave nest on the cliff of the owl. At first, he didn't understand what the owl was going to do with this pile of stones, and it didn't look like laying a nest. Could this owl make a "landscape" of its nest?

But after searching the owl's memory picture, he found a picture of hunting and drinking blood and swallowing stones. Xiang Kun had a guess:

is this the way for owls to restrain their drowsiness after drinking blood and return to their nests and sleep again?

You know, the wild is not like the city, there are all kinds of dangers in the deep mountains and dense forests.

Xiang Kun bought meat rabbit in the vegetable market and raised it at home. When he needed it, he killed the rabbit and drank blood. After drinking, he fell asleep. Unless his relatives and friends couldn't contact him in an urgent matter, he might come to visit him. Otherwise, there would be no disturbance and no danger.

But if the owl wants to drink blood, it needs to hunt by itself. Because if the blood leaves the body for too long or the prey dies for too long, it will have no effect. So basically, it will drink blood directly on the spot or transfer it to nearby places to drink blood, instead of catching the prey back to its nest. After all, many of the prey it hunts after mutation are of large size.

In this way, if the owl, like Xiang Kun, has a strong drowsiness after drinking blood, and has a long sleep time and is not easy to wake up, it is dangerous to find a place to sleep in the wild.

So it swallows the stone into its stomach to restrain sleepiness. It flies back to its nest and spits out the stone in its abdomen before it goes to sleep.

Otherwise, it is impossible to explain why it swallows stones and spits out from its nest on the cliff. After all, after all, it only drinks blood after mutation, and can't eat other food. It doesn't need to swallow stones to promote digestion.

As for why stones are more suitable for "eating" than meat or other plants, Xiang Kun speculates that stones are more simple and dense, and they are more likely to be suppressed when they feel vomiting, and they are easier to vomit when they feel like vomiting.

Of course, all these are just Xiang Kun's reasoning and speculation. Whether this is the case or not, he is going to do the experiment himself when he goes back.

If it works, it's also an occasional emergency.

It's like that after the battle with owls that day, if he can stay up for a while by this method, he may be able to see the disappearance process of the owl's body, which is of great help to his understanding of the variation factors in himself and the owl.

Of course, it's more important to avoid sleeping in unsafe places for a long time.

Although the reason for this owl's variation has not been found this time, it is also very helpful for Xiang Kun to understand himself from the traces of its habitat and the comparison of memory images.

After all, according to the fact that there will be a deep sleep and mutation after a hunting and drinking blood, the number of variation of this giant owl is much more than that of Xiang Kun.

No matter from the frequency of variation or time, it is Xiang Kun's "great elder".

Moreover, the four-and-a-half days of life in the mountains also let Xiang Kun better experience the improvement and change of body functions after this mutation, and further familiarized and trained.

In addition to the night vision ability obtained from the owl's blood, his dynamic vision, hearing and smell have been significantly enhanced, and this enhancement is not only the enhancement of sensitivity.In the mountains and forests, he has a very strong ability to distinguish the sounds and odors caused by many other creatures, which was not available before Xiang Kun of urban life. It is equivalent to that he directly owns the "database" of owls in hearing and smell.

This makes it very easy for him to survive in the mountains and forests. He often feels that the world is in my control.

Sometimes he even thought, if only he had the flying ability of an owl.

Of course, this is just to think about it. If he wants to mutate a pair of big wings now, he can only live in seclusion in the mountains and forests.

……

On the road around the mountain, Xiang Kun suddenly stopped, stood at the side of the road and looked back at the mountain.

Naturally, this side is not a "deep mountain". It is far away from the area where he is in these days. Although the development degree is still not high and there are few people, at least Panshan highway has been built. There are villages and temples on the mountain. Occasionally, villagers drive up and down the mountain, and some pilgrims go to temples to offer incense.

Xiang Kun stopped because he heard the sound of the car. More than ten seconds later, an SUV appeared at the corner.

He raised his right hand and, compared with his thumb, made a gesture asking for a ride.

To be honest, he was not very hopeful. Four downhill cars had passed by him before, and all of them did not respond to his "praise hand" and had no intention of parking.

Of course, he has nothing to complain about. Even if he is driving in a change of position, he will not stop when he sees such a big, dusty, barefoot, bareheaded man on the side of the road.

In any case, he ran all the way, and sometimes "cut short", which was not much slower than taking a ride. There were too many curves and too fast on the mountain road, and no one dared to drive fast even when he went down the mountain.

He had checked the map when his mobile phone had a signal before. There was a big village at the foot of the mountain. He should be able to hire a car to take him to the nearest county or town and buy a ticket to go home.

But this time, he was lucky that the SUV stopped by his side.
