Li Jian nodded, indicating that he understood.

Now, he had thirty-three ordinary corpse cores in his hands, as well as two purple corpse cores that belonged to giant zombies. Originally, Li Jian shouldn't have taken the corpse core after killing the little giant zombie. It's just that everyone agreed that it was Li Jian's credit for killing the little giant zombie, and after a few pushes, it went into Li Jian's pocket.

Since the discovery of the existence of the corpse nucleus, Li Jian has been studying it. Because, every time he killed a zombie, he could feel that he had absorbed something very faint like energy from it. But with his conditions and knowledge level, he didn't come up with anything in the end, so he could only use what Lu Tianxing said, it was more cost-effective to take the corpse core and exchange it for wall coins with the research institute.

The research institute is responsible for the acquisition of the corpse nucleus is a beautiful woman in a white coat who looks about twenty years old, is one meter seven tall, has snow-white skin, long hair to the waist, a very delicate face, and a concave and convex figure, it is hard to imagine that such a big beauty would be responsible for the acquisition of the corpse nucleus in the research institute.

"Newcomer, are you stunned?"

Lao Hu also got a lot of corpse cores from this investigation outside the wall, so naturally he followed Li Jian over to exchange wall coins.

"In this wall of life, I don't know how many people want to fight this girl's idea, even the reformers are not a few. But it's a pity that this girl is said to be a well-known scientist before the end of the world, and has published many papers in any magazine, and now her full-time job is to study zombies with Professor Sun, and her status is much higher than that of many changemakers. There are countless people who want to fight her idea, but there are no people who dare to fight her idea. Alas, what a pity......"

After that, Lao Hu also made a sigh, which was really regretful.

There are a lot of people who come to the research institute to exchange the corpse core for wall coins, almost all of them are investigators, but after all, the process is very simple, and there is no need to do any registration, just throw down the corpse core, and you can leave with the wall coins, which is quite efficient.

"Thirty-three ordinary corpse cores, two p-shaped corpse cores, all exchanged for wall coins."

Li Jian put all the corpse cores on the table, and the two completely smooth oval-shaped purple corpse cores were particularly conspicuous in the pile of gray corpse cores, like candlelight in the dark, which was impossible to ignore.

"Oh?"

The beautiful scientist couldn't help but look up to see who the Holy came to exchange for wall coins. Because very few people will exchange the corpse core of the evolved zombie for wall coins, there are only one or two for several days, and now this person has taken out two at once, and she can't help but be curious.

When she saw that the person who came to exchange the wall coins was a very young, even immature young man, the look of surprise on her face became even stronger.

"What's wrong?"

Li Jian saw the surprised expression of the beautiful scientist and asked subconsciously.

"You're an investigator, right? New to the new arrival? ”

The voice of the beautiful scientist is very good, which makes people feel very comfortable.

"Hmm."

"Is this your record? Are you a changemaker? ”

Li Jian instantly figured out the reason, it was that he took out the corpse cores of two evolved zombies at once, it was too scary, and it was not like a person like him could do it at all, which caused the surprise of this beautiful scientist.

"I'm not a changemaker, but that's my record, huh...... It's just a fluke. ”

The beautiful scientist smiled slightly, but didn't ask anything more, but secretly noted Li Jian's appearance. After all, it is still not easy for a newcomer to be able to take out the corpse core of two evolved zombies at once.

Thirty-three ordinary corpse cores, exchanged for sixteen wall coins, about two corpse cores exchanged for one wall coin, rounded and settled, it stands to reason that Li Jian can still recover an ordinary corpse core, but he is troublesome and gives it to the beautiful scientist. As for the corpse cores of the two giant zombies, they were exchanged for one hundred wall coins. The conversion ratio is 1:50, which shows how valuable the core of the evolved zombie is. But of course, the difficulty of killing evolved zombies is not comparable to the difficulty of killing ordinary zombies, which is also the reason for the high price of the corpse core of evolved zombies.

At the end of such a day, Li Jian's assets already have more than 200 wall coins, and he is almost the upper class in the wall of life, and he is the kind of person who does not have to worry about food and housing. Due to the "subsidy" of this first out-of-wall survey, Li Jian is still not short of food, so he went to the material supply and demand point to spend ten wall coins to purchase some daily necessities, and dragged his tired body back to the dormitory building.

At this moment, it was already close to six o'clock in the afternoon, Li Jian returned to the dormitory, locked the doors and windows, closed the curtains, took a shower, and after eating something, sleepiness surged up, tilted his head, and fell asleep on the bed.

On the other side, in the research institute of the Wall of Life.

The beautiful scientist put a large bag of corpse cores on the sterile workbench, and then poured them all out at once, among the two hundred gray corpse cores, two purple corpse cores that belonged to the giant zombies were particularly conspicuous, and the beautiful scientist couldn't help but take a few more looks.

"Professor Sun! I've sent today's corpse nucleus! ”

The beautiful scientist shouted to a figure opposite.

"Oh! It's Xiaoying! It's really hard for you, and I have to trouble you to buy the corpse core every day. ”

"It's just a small thing, isn't there a shortage of manpower in the research institute now? Besides, let those little assistants take so many wall coins to buy corpse cores with them, Yu Shuai won't agree, right? ”

"That's right, that's right."

Professor Sun said as he walked over to the workbench.

The study of corpse nuclei can be said to be one of the basic tasks of studying zombies, and Professor Sun, as a changemaker with diffusion reconnaissance capabilities, can learn a lot of information by studying the S diffusion force field emitted by corpse nuclei. Therefore, every day after the beautiful scientist Lin Ying acquires the corpse nucleus, she will bring it to study with Professor Sun.

Seeing the purple nucleus in the pile of gray corpse cores, Professor Sun's pupils shrank slightly, but he didn't pay much attention to it. It's not that he hasn't studied the core of the evolved zombie, so he won't make a fuss.

In this way, Professor Sun and Lin Ying picked up the corpse nuclei one by one, and after the tests of several strange machines, as well as various tests, they kept remembering something on the thick paper. Rows and rows of data are densely packed and dizzying.

There is no difference between an ordinary corpse nucleus and an ordinary corpse nucleus, which is the conclusion reached by Professor Sun and Lin Ying after nearly two months of research. Therefore, studying the corpse nucleus like this every day is actually an extremely boring process, and both of them have relied on perseverance to persist until now.

After writing down the exact same data on the paper, Professor Sun picked up another ordinary corpse core as usual and put it in front of his eyes to observe it carefully.

Just when he thought that this would not change, his pupils suddenly contracted violently, and the hand that grabbed the corpse core subconsciously became more and more forceful, and then cried out in a lost voice.

"Xiaoying! This nucleus!! ”
