Chapter 329: Exchange Origin Stone

"plz follow me."

The steam self-propelled machine said without emotion, and finally turned around and walked towards a narrow road.

Seeing this, Zhang Tuohai quickly followed.

The hall is very huge and filled with all kinds of flowers and trees, it looks like a huge botanical garden.

Walking in the botanical garden, Zhang Tuohai felt a sense of time and space dislocation.

In a world of apocalyptic wasteland, there is such a huge botanical garden, which is really incredible.

Zhang Tuohai followed the steam self-propelled machine through the huge botanical garden and came to a smaller room.

This is a huge study, surrounded by huge bookcases, filled with various books and parchment scrolls.

In the very middle of the room, there was a huge brass coffin. Several metal pipes were connected to this huge coffin, and the air-conditioning was continuously fed into it, so that the whole coffin seemed to be like ice.

Zhang Tuohai had just stepped into the room, and the brass coffin was slowly erected.

Through the crystal lid, Zhang Tuohai could see a silver-haired girl lying in the coffin. She looked almost the same as Lilith, and her whole body was covered in ice.

It's just that the right half of her cheek is wrapped in brass, not the left half like Lilith's.

"Did you bring my sister's handwritten book?" There was excitement in the girl's eyes.

"That's right, it's here." Zhang Tuohai handed the letter left by Lilith to the steam self-propelled machine beside him.

The steam self-propelled machine took the letter and unfolded it in front of the girl.

"That's right, that's it, the secret words above are not wrong, it's what my elder sister left behind." The girl looked very excited.

"My sister she..." The girl turned to look at Zhang Tuohai.

"I'm sorry, she has jumped into the holy mountain and detonated the holy mountain. Now, the whole world is in doomsday."

Zhang Tuohai said.

"I can imagine that this is my sister's final wish, and now, she finally gets what she wants."

The girl sighed.

"My condolences," Zhang Tuohai said.

"I had long anticipated that such a day would come, and my heart was already prepared."

the girl said.

"Thank you very much for bringing my sister's letter, so what is your purpose here?"

the girl asked.

"If I'm not mistaken, it's Originium, right?"

"Yes, I want to get a source stone." Zhang Tuohai nodded and admitted his idea.

Since seeing Lilith detonating the holy mountain with Originium, Zhang Tuohai has been fascinated by the great power of Originium.

If he can also get an Originium, he will get a hole card that can turn the table at any time.

The reason why he had to travel thousands of miles to come here, in addition to avoiding the doomsday disaster, the most important purpose is to get a source stone.

"Origin Stone? Sure enough." The girl's face showed the look that she expected.

"I do have the source stone, but have you figured out what to exchange it for?"

As the girl spoke, a secret door on the surface of the brass coffin popped open automatically.

There is a groove in the secret door, and a source stone is embedded in it, which looks the same as Lilith's.

"This Originium is the source of my life. If the supply of Originium is cut off, I may not be able to live for a day. What do you think you can take out to exchange for this Originium?"

"I suggest you change the conditions, such as some of the design drawings left by my sister."

The girl said: "I can call the shots and let you choose three design drawings to take away."

To be honest, Zhang Tuohai was moved when he heard the girl's words.

Lilith's design drawings are all fine, and if he can choose by himself, he is confident that he will be able to raise his combat effectiveness to another level, and even raising the car to level 5 in one fell swoop is not impossible.

However, Zhang Tuohai didn't want to miss the power of Originium.

This is something that can save a life or lift a table at a critical moment. Compared with it, a few drawings seem to be nothing.

However, listening to the other party's meaning, this source stone is an important thing for the other party to maintain life. If there is no source stone, the other party will die.

Things seemed to come to a dead end.

However, Zhang Tuohai still wanted to give it a try.

"You just said that Originium is the existence that maintains your life, so can you tell me the specific reason? Maybe, I can help solve this problem."

"You really don't give up." A smile appeared on the girl's face, "Alright, for the sake of your sister's letter, it's no big deal to tell you."

"A few years ago, I was seriously injured by an explosion in an experimental accident, and my life was in danger. I thought I would die, but my sister refused to give up. She obtained two Originium, and she transplanted her body to me. , and then use the energy of Originium to fuse my head with her body, allowing me to survive smoothly. However, there was a problem with the treatment, her body and my head could not be fused, and I could only barely maintain this pair. look."

"Then why not make a steel body?" Zhang Tuohai showed a curious look.

He remembered that Lilith's entire body was made of steel except for half of her head, and the girl in front of her was also transformed into this look, right?

"If it was feasible, I would have done it already," the girl's face showed a sad look, "However, my body can't be docked with steel, and I can't be like my sister."

"No wonder." Zhang Tuohai showed a clear look.

Now, what troubles the girl is the body's rejection reaction. If it was in his world, I'm afraid he would have died a long time ago. That is, this world has something like Originium, so that the other party can barely continue his life.

Now the crux of the matter comes to rejection.

If the rejection reaction can be eliminated and the girl's body and head can be fused, then the problem will be solved, and he can also get the Originium.

However, how to eliminate rejection?

Zhang Tuohai thought about it.

Now, he regrets that he sold the source of blood and the source of zombies. These two are excellent comprehensive recovery potions, and their recovery capabilities are not weak. If they are given to the other party, they may be able to clear the rejection reaction.

However, he has sold it to Li Feiyu, and now it seems to be a bit of a misstep.

He still has a similar medicine in his hand, that is, nanomachine injection.

This thing has a similar effect, even more powerful.

Not only does it not have the negative effects of those vampires and zombies, but it can also transform people into mechanical life.

However, there is a certain success rate.

This was originally used by Zhang Tuohai to gamble his life when he was seriously injured, but now it seems that it can be used to exchange Originium.

I just don't know if they want to.
