Although I didn't buy the books I needed, the knowledge in the books had already been scanned into the database of Tianshu, and I got it directly into my mind little by little at night.

When you want to take it out and taste it slowly, you can just pull it out in the database.

With these things, I was able to read the series of books that I couldn't read before, and I quickly integrated them, and the progress was simply fast.

And during this time, Xiao Hei actually woke up from the "sleep mode".

"Meow~"

"Gollum Gurg~"

Xiao Hei, who had just woken up, was intoxicated by Dong Chen's touch, and Dong Chen looked at Xiao Hei, who was fat in his arms and had also played several laps, with a speechless face.

"It's really a pig......"

During this time, Dong Chen was busy with his "studies", and he really didn't pay much attention to Xiao Hei, he just prepared food and water for him and didn't care, and he didn't even know when he woke up and ate it, anyway, the food and water were gone as soon as he woke up the next day.

But today Xiao Hei woke up, and jumped directly from the bed to his arms, and suddenly Dong Chen felt that Xiao Hei's weight had increased a lot, and his body size had also increased a lot.

After taking a closer look, I found that Xiao Hei's body size was close to the size of an adult domestic cat, and I don't know if it was due to the fact that he only ate and did not exercise, Xiao Hei's current body shape was a little fat.

However, it is still a juvenile, so although it is the size of an adult domestic cat, it can actually be seen at a glance that it is still a small one, like a fat tiger cub.

In addition to the change in body shape, Dong Chen also found that the hair on the tip of its tail turned golden, especially when it was stroked by himself, the tip of the tail would gradually turn from black to gold.

Or can you change it according to your mood?

Characteristics of chameleons!

After discovering this phenomenon, Dong Chen became interested in Xiao Hei.

Originally, it was only raised as a kitten, but I didn't expect it to have such a strange ability.

After Dong Chen's careful understanding, he found that the strangeness of Xiao Hei was not only the handful of hairs on the tip of the tail, but the black hairs that were not "hair", but the part of the nerve tissue that extended out of the body.

It's just that it has evolved to be controlled internally, but the extension part is not very sensitive, and it feels like hair.

There are a large number of pigment granule cells in these epitaxial nerves, and as long as the pigment in these cells is concentrated or diffused, Xiao Hei can change color.

The pinch of golden retrievers at the tip of the tail is the control change, and it is also where the pigment particles are most active, and this activity is slowly extending from the tip of the tail.

And in the process of research, Dong Chen also found that Xiao Hei became smarter after waking up.

The current Xiao Hei is very sensitive to Dong Chen's voice, and can even understand Dong Chen's simple commands, especially the barbarian language commands.

Regarding this situation, Dong Chen understood after a little thought, Xiao Hei followed him every day when he was in the barbarian tribe, and he also tried to train Xiao Hei, and even Da Zhuang also participated.

It's just that Xiao Hei was too young at that time, and the training effect was not obvious, but what they said in the barbarian language, Xiao Hei probably remembered everything.

Now that Hei is smarter, of course he remembers the commands of the barbarian language vividly, and after hearing them again, he begins to understand them.

And the brain has become smarter, which is also quite important for controlling the discoloration of pigment granule cells, which is a good phenomenon.

Of course, Xiao Hei is still too young, not much smarter, and his ability to control the details of his body is still limited, and he can't control the changes in the color of his tail tip well.

So in addition to reading and drawing, Dong Chen has one more task, that is, to train Xiao Hei.

Training it to listen to passwords, train its movements, train its control ability, etc., these were originally the tasks of the big cat, but since Xiao Hei's parents are gone, Dong Chen has to take on these responsibilities.

By the way, in the process of training, it can be regarded as a process of understanding and research.

With the cooperation of Tianshu, even if Xiao Hei had any slight changes, Dong Chen could know that it was this subtle change that determined the results of the training.

According to the data tips of Tianshu and constantly adjusting the training plan, Dong Chen finally formulated the most reasonable training method, so that Xiao Hei's progress was fast.

At the beginning, Dong Chen only let Xiao Hei stay in the house, but now Xiao Hei is different from the stage of "eating, sleeping, sleeping, eating", and he also needs companionship.

So after the training had certain results, Dong Chen took Xiao Hei to the library.

However, this matter has to be passed through Harry the Administrator first.

Looking at Xiao Hei, who was obediently squatting on the counter, Harry, the administrator, had a rare look on his face, "There is no rule that you can't bring pets into the library, but there is another rule that you can't damage books." ”

"You know, sometimes animals behave unpredictably, so theoretically I can't agree with Blackie staying in the library."

"I understand the reason," Dong Chen also agreed, "but Xiao Hei is really well-behaved." ”

Saying that, Dong Chen said to Xiao Hei, "Xiao Hei, pretend to be dead." ”

When Xiao Hei heard this order, he fell directly to the side and didn't move.

It's not enough to lie down, Dong Chen also went up and pushed Xiao Hei, pinched Xiao Hei's meat pad, and Xiao Hei still didn't move.

"Look, Administrator, I'll just say it's very obedient, and it will never destroy books."

Taryn Harry was also a little curious, so he also went to poke Xiao Hei and found that this little guy was really clever and motionless.

Very cooperative, whether it was the host or not.

Seeing Harry's look of admiration, Dong Chen said, "Xiao Hei, get up." ”

Xiao Hei got up in response, and immediately became a well-behaved sitting posture again.

"Well, I didn't lie to you, administrator," Dong Chen was very satisfied with Xiao Hei's performance.

"This little creature is indeed very clever and obedient," Harry was still a little embarrassed, but he opened a small opening, "It's not impossible to let it stay in the library, but can you vouch for it?" ”

"If you vouch for it, and you're responsible for what happens, I'll let you bring it in."

"No problem," Dong Chen patted his chest and said, "I can vouch for it, if there is any loss, I will be responsible, and I will make it quiet and will not affect the students' learning." ”

"If you don't say that I forgot, I'll add another one, and if there is a student complaint, you should take it out immediately." The administrator added.

"Okay, I promise." Dong Chen assured again.

Seeing that Dong Chen had come to this point, what else could he say, he could only agree.

In this way, Dong Chen's work in library management has changed again.

As for complaints, it is impossible to complain, and there is no student union to complain.

The shovel officer is not only on earth, but also on any planet for such cuties.

Xiao Hei is very quiet and obedient here, and the more well-behaved he is, the more likable he becomes.

Even, a bit too much.

Dong Chen was flipping through the books there, Xiao Hei was playing next to him, without making a sound at all, and occasionally ran to other students, curiously watching others read.

This situation makes students want to touch it, but they dare not touch it.

And Dong Chen was tired of reading, so he took out a sketchboard to draw Xiao Hei, Xiao Hei has various forms, and as soon as he drew it, he was politely asked by the student to leave.

That's right, now the students are no longer afraid of Dong Chen, and they don't hide from Dong Chen, as a painter with a cat, he has faint signs of becoming a student idol.
