Chapter 349 365. Zombie World 57
After hearing Zhang Yaowen's explanation, Li Changsheng was skeptical. Is there really someone in this world who can cross dimensions?
"Are the histories of the two worlds similar?"

Zhang Yaowen directly took out the history book he brought with him and handed it to Li Changsheng.

Li Changsheng flipped through it briefly. "Most of the previous ones are the same, but it's different when it comes to the Song Dynasty. There is a deviation when it comes to Zhao Gou of the Southern Song Dynasty. We don't have the Yuan Dynasty here, but the Xuan Dynasty."

Zhang Yaowen certainly knew this. He had also looked up the history of this place these days. "In fact, they are from the same clan and the same origin. The time difference between the two planes is not much, only two years..."

The two discussed this issue again, both looked incredulous. Li Changsheng also believed that Zhang Yaowen and the others really came from another world.

There was a bit of scrutiny in his eyes, "You said you came here mainly to trade supplies, I wonder how you got this cross-border express delivery?"

If they could also obtain this magical object and cross over to other dimensions, could they also seek help from other dimensions?

Zhang Yaowen, "We really don't know about this. We are just following the arrangements. But don't worry, when the time comes, we will naturally go back and will not stay here."

Zhang Yaowen answered the other party vaguely, and Li Changsheng looked a little regretful, but he didn't know whether he believed it or not.

"I just don't know what you use these crystal cores for. Can you tell me?"

Li Changsheng took out from his pocket the crystal core he had been studying these days. He really couldn't figure out what it was and didn't know why these people were so keen on collecting it.

Now that he heard their origins, he couldn't help but become alert. He didn't think they had crossed dimensions just to have fun. There must be some secrets here that he didn't know.

Zhang Yaowen smiled bitterly, "We also read about this stuff in a book. We thought it was interesting so we collected some. It's up to you to research what it's used for. We'll do further research on it when we get it back to see if we can overcome these viruses."

Bai Qinghe's eyes moved slightly. It turned out to be Brother Zhang. He believed it.

"So you don't know what it's for either of you?" Li Changsheng didn't fully believe it. It was impossible for Zhang Yaowen and the others to cross dimensions to do these meaningless things.

……

The two sides chatted back and forth for a long time. Yun Tutu couldn't stand the looks from these people, so he found an excuse and went back to the RV.

But even while sitting in the RV, he could hear every word of Zhang Yaowen and the others' conversation.

Neither of them was a simple person. They tested each other back and forth. Yun Tutu couldn't help but put out fruits and vegetables and ate while listening. There was a lot of swords and knives in their conversations, and she couldn't handle it.

When it came to material exchange, Yun Tutu couldn't help but sit up straight. Although the price offered by the other party was fair, it was still far from what he expected.

But there is no way around it. If this happens a few years after the end-of-the-world disaster, all supplies will be scarce, and the people who hold the supplies will take the lead.

Now that Li Changsheng and his men have received such a large amount of supplies, they certainly don't attach much importance to the supplies that Zhang Yaowen and his men mentioned.

Li Changsheng agreed to the exchange because he knew that some things would be non-renewable in the days to come, so he could accept it while the gap in the current transaction was not too big.

It is said that in troubled times there are gold, and in prosperous times there are antiques. I don't know when this world's chaos will end. When that time comes, how long can these things be preserved? It can be exchanged for a batch of food, and the base can also take in more survivors. For him, it is a win-win situation.

After everything was agreed upon, Li Changsheng said to Zhang Yaowen cryptically, "I will discuss this matter with you myself. When we get to the base, we can make the deal privately."

Zhang Yaowen glanced at him and nodded, "There is no problem on my side, but we are not responsible for any subsequent troubles after entering the base."

They don't want to get involved in factional fighting.

Li Changsheng nodded and assured, "I am still thinking about long-term cooperation in the future, and I don't want to embarrass you. But if you have the opportunity to come here next time, remember to be the first person you think of for cooperation."

Zhang Yaowen, "I hope I can come back again. I also want to find out what this crystal core does."

Thinking that Li Changsheng had no ill will towards them from the beginning till now, he reminded them, "These crystal cores exist for a reason. If you are not sure what they are used for, try to collect as many as possible."

There are also many scientists in this plane. It is only a matter of time before they figure out the functions of these crystal cores. Now it depends on who has a longer-term vision and can master them first.

Li Changsheng nodded. Even if Zhang Yaowen hadn't reminded him, he had already given orders to his men to collect as many crystal cores as possible when fighting zombies. Many people also had the same idea. These days, there were survivors who took the initiative to help deal with the zombies that were killed, and secretly followed behind to pick up the leftovers.

Because they discovered that after Zhang Yaowen and his team killed the zombies, they did not dig out the crystal cores from every zombie, there were always a few that slipped through the net.

Li Changsheng could understand these people's thoughts, and told his subordinates not to stop them or argue with them. This was a good phenomenon, as everyone was slowly adapting to this world and slowly facing difficulties.

"We will try our best to collect the information. We will stay here tonight and rush to the base at full speed tomorrow. We will travel together then." Li Changsheng was afraid that these people would leave without saying goodbye again, so he hurriedly said hello in advance.

"That's no problem. We can follow the team tomorrow. We can discuss the details when we get to the base."

Li Changsheng also knew what they were thinking. Zhang Yaowen and the others didn't want to be disturbed and were prepared to hide among the survivors, so he just let them do what they wanted.

Zhang Yaowen brought Bai Qinghe to the car, took the water handed over by Yun Tutu, drank a few sips, and then said, "Next we have to follow the team and complete the transaction at the base before going back."

Yun Tutu, "Then we have to make a disguise. Don't forget, information is flying everywhere now. If we go out in this RV, we won't be recognized at a glance."

"We're not afraid of the RV, but we three have to disguise ourselves."

None of these things could stop Zhang Yaowen and the others. After dinner, he took Bai Qinghe to clean up in the car. When they appeared again, they had two completely different faces.

Zhang Yaowen wiped his silver hair and when he opened his mouth, his two front teeth were missing.

Yun Tutu couldn't help but take a closer look. If you don't look carefully, you really can't see the teeth stickers, and you don't know how they are made.

Bai Qinghe hunched his back slightly, he was still the same person, just looking timid, no one would compare him with the man who was killing everyone and throwing the puck randomly.

The two of them cast their eyes at Yun Tutu at the same time, and Yun Tutu was so scared that he quickly waved his hands...
