Wang Chen finally got his wish to see Xu Cheng, although Xu Cheng didn't have a good face when he saw him, but he didn't care at all, after all, the reason why Xu Cheng met him, those threatening videos played a great role, no matter who was threatened and had to show up, they would be hostile to the threatener.

Xu Cheng is okay, Wang Chen Hunter tracked Xu Cheng just coldly to him, and he didn't have any obvious hatred for him, otherwise he wouldn't dare to come out to meet Xu Cheng for the sake of safety.

Wang Chen followed Xu Cheng into an inconspicuous room from a small alley next to the back door of the Academy of Biological Sciences, after entering the room, Wang Chen quietly looked at the environment of the room, the room was very simple, except for a set of dilapidated tables and chairs, there was only a wooden bed with bricks as the foot.

"Young man, you have learned a lot from Lao Dong, I hid so deeply that you found out." At this time, Xu Cheng, who was sitting on the edge of the bed, said to Wang Chen with a cold face.

"Huh! There is nothing difficult in the world, but I am afraid of people with a heart, as long as I am willing to look, I can always find a living national treasure like Professor Xu. For example, Old Jack in the other hemisphere of the Blue Star, you seem to have been in contact with it once not long ago. Wang Chen didn't explain Xu Cheng's mistaken belief that he found him with the help of Dong Hua, but faintly pointed out that his ability was far more than that.

"You do have some abilities, but if you think that these secrets you have can threaten me and make me go with you, then you are wrong." Xu Cheng said with slightly squinted eyes.

"I also hope that Professor Xu can willingly follow me, but since Professor Xu really doesn't want to, I won't force it, but I hope to be able to get all the skills of Professor Xu's biochemical bones, and of course I will pay the price I should pay." Wang Chen said seriously.

As the saying goes, a twisted melon is not sweet, since Xu Cheng is really unwilling to go back with him, Wang Chen does not intend to be reluctant, as long as he can get all the technology in biochemical bones, Dong Hua can integrate the kind of substance he invented into Bai Xue's bones, then the two months spent on this trip to the desert green boat base will not be in vain.

"Since you know about biochemical bones, then you must know that if you want to get this kind of technology, you can't buy it if you have a survival point, and the price you have to pay is unimaginable to ordinary people."

Xu Cheng didn't expect Wang Chen to let him go for the sake of biochemical bone technology, but biochemical bone technology was one of the most proud inventions in his life, and he wouldn't let Wang Chen get it easily, otherwise he, the former chief bioengineer, would not be too worthless.

"So if Professor Xu has anything that needs to be dealt with, just just ask me, as long as there is a chance, I will do my best to help you do it." Wang Chen did not threaten Xu Cheng again this time, but hoped to express his sincerity through his actual actions.

"You should know that to use biochemical bone technology on people, ordinary people simply can't bear the pain caused by surgery, and they must have a fake death potion that can temporarily close all the consciousness of the recipient before they dare to perform surgery, and now I don't have the most important main medicine to make this medicine, Huangquan Cao, so if you can find Huangquan Cao, I will not only give you the biochemical bone technology, but also give you a fake death potion." Xu Cheng thought for a moment and said.

"Good! Deal! "Now that Xu Cheng has already offered the price, Wang Chen is no longer dragging his feet, and besides, if she can find Huangquan Cao to make a fake death potion to operate on Bai Xue, she doesn't need to endure that inhuman torture, why not?

"In that case, then I won't keep you any longer, and come to me when you find Huangquan Grass!" Xu Cheng expressed his thoughts to Wang Chen without the slightest pretentiousness.

"Then I'll go first, please rest assured, I won't bother Professor Xu again until I find Huangquan Cao." Wang Chen also stopped pestering and turned to leave.

After leaving Xu Cheng's room, Wang Chen asked No. 4 to help him collect information about Huangquancao on the Internet, and in less than two minutes, No. 4 helped him sort out the information about Huangquancao.

Huangquan grass is a highly poisonous herb, the poisonous gas it emits can paralyze the nerves of all creatures that inhale the poisonous gas within a range of 200 meters, so that the creatures lose control of the body, and then fall to the ground and slowly die, after the death of these creatures, the corpses will quickly decay and integrate into the soil near it, and it depends on the decay of these corpses to moisten the nutrient-rich soil to grow. That's where its name comes from, as long as it exists, it is bound to be full of bones, and even mutated monsters can't escape its clutches.

However, Huangquan grass is an extremely precious and rare herb, and its rhizomes and leaves contain a substance that can temporarily seal the consciousness of living beings, which can be used to make anesthetics with excellent effects, and the feigned death agent is one of the most effective.

And the reason why it is precious is because there are many injured people in the last days, most of these people will have stumps, and after the stump limbs, they will generally transform the lost parts into mechanical limbs, and in order to make their mechanical limbs truly become part of their bodies, these people will connect the nerves with the mechanical limbs, and the pain of the recipients during the connection operation can be imagined, so the value of the anesthetic made of huangquan grass is reflected at this time.

Wang Chen knew that Huangquan grass was not easy to get, but he didn't expect it to be so difficult to get, the only place where Huangquan grass was more abundant in Central Continent was the Mogan Desert outside the desert green boat base, to be precise, the hinterland of the Mogan Desert, the alien corpse desert, because there was the most ideal nutrient provider for the growth of Huangquan grass - the alien corpse.

Alien corpses wander in the desert almost all the time while absorbing the blood energy reflected by the blood moon and the Titan Star, and the wandering creatures are precisely the main source of food for the Yellow Spring Grass, and the fear of the death of their own kind will make them instinctively avoid the poisonous gas forbidden area of the Yellow Spring Grass, and those unconscious alien corpses will continue to move forward without fear even if they see their kind falling under the poisonous gas of the Yellow Spring Grass one after another.

Therefore, the Alien Corpse Desert, which has countless alien corpses, has become the most ideal place for the survival of Huangquan grass, and the reproduction of plants makes it possible to have a small amount of Huangquan grass in the Mogan Desert, where there are often alien corpses.

Wang Chen searched for a long time on the Internet and finally found a message for the sale of Huangquan grass, but the yellow spring grass was also on the other side of the world at this time like Dong Hua's old friend Old Jack, and he finally sighed and had to face the fact that he had to leave the base to find Huangquan grass in the desert outside the jungle.

"I know that this old guy Xu Cheng will give me a problem, but if you think you can easily scare me away, then you are very wrong, especially now that I have herbalogy, this matter will be even more difficult for me, and when the time comes, I will make you lose your wife and soldiers." Wang Chen glanced back at the room where Xu Cheng was, and thought hatefully.
