Zhang Hai tangled for a while and had to give up.

Jiang Zhuying and others entered the hall to exchange for supplies.

Jiang Zhuying looked in a good mood and couldn't wait to be able to exchange for the new weapon she had always dreamed of.

The rest of the people are similar. When they come here, they can replenish bullets and other items, and can also see if they can change it.

In addition to exchanging supplies, when you come to a place where there are many people, you can also carry out some "buy, buy, buy" activities like this, which is a kind of adjustment to their nervousness that they always fight with zombies and the loneliness of living in the zombie group.

Seeing these survivors and Jiang Zhuying were all busy with their own affairs, Jiang Liushi walked to a table.

The facilities in this hall are actually very simple. Except for the two windows that already exist, the rest are office windows made of tables, with one or two soldiers sitting behind them.

There were also some survivors in the hall, constantly arguing with one of the soldiers at the table, probably arguing endlessly about the amount of supplies they had received.

Jiang Liushi slowly walked to a table in the corner and asked, "I have some supplies I want, I wonder if you have one?"

A young soldier sitting behind looked up at Jiang Liushi and asked casually: "What do you want?"

Some people who often come here already look familiar, but this young man in his twenties has a naive face. However, this soldier has seen that Jiang Liushi is with Jiang Zhuying and others.

"One hundred kilograms of titanium, and..." As soon as Jiang Liushi said the first word, the soldier was stunned for a moment, and then he listened backwards, and became more and more surprised.

Although survivors come to exchange various materials, this is the first one to exchange so much metal.

What survivors need are materials or weapons that are necessary for survival. What is the use of requiring these metals?

The soldier took a look again and saw that Jiang Liushi didn't seem to be joking. He showed a strange look and said, "I'll check it out for you."

I don’t know if they built a LAN here, but the soldier started searching on the computer in front of him.

Jiang Liushi waited patiently. If the military already had reserves, it would be good. If not, then they could only let them set up a list for other survivors.

A few minutes later, the soldier raised his head and said to Jiang Liushi: "No, there is no reserve."

There wouldn't be any survivors who collect this kind of thing specifically and then exchange it for supplies. These things will never be mentioned in the military's demand list.

"Then..." Jiang Liushi was about to ask about Bu Qinglist when a voice suddenly penetrated into the side.

"Iridium? What do you want this? But this thing can be found in our school."

Jiang Liushi immediately turned his head in surprise. The person who spoke was an old man in his sixties. He didn't look like he was with the survivors who came to exchange supplies. He was dressed dirty and had mud on his hands, like an honest farmer.

"Your school?" Jiang Liushi asked hurriedly.

In fact, most of these metals are just difficult to find and are not particularly scarce, but iridium is the hardest to find and the smallest quantity.

Things like iridium are generally used to make pen tips. How big is the pen tip?

One kilogram of iridium is already a lot.

"What I want is one kilogram of iridium." Jiang Liushi added.

If the old man told him to go to school to pull out the pen tip, he would be speechless.

The old man was wearing glasses and heard Jiang Liushi seemingly questioning, he said, "One kilogram... there are some. There are several Iridium crucibles in our school's laboratory."

Iridium crucibles are used to conduct chemical reaction experiments, and are generally available only in national key laboratories of universities.

This is not Jiang Liushi's major. He didn't think of this at the beginning. Now, when he heard the old man say it, he suddenly realized it.

"Are you talking about Jinling University?" If it is Jinling University, then it is close to Jiang Zhuying and the others' residence.

"Yes." The old man nodded.

"Thank you!" Jiang Liushi was overjoyed. In this way, he could collect the most difficult materials here.

"Old man, can you tell me where this laboratory is?" Jiang Liushi asked. Jinling University is very large. Even Jiang Zhuying may not know where this laboratory is.

The old man moved his lips, then wiped his hands on his clothes twice, and asked, "Do you have any paper and pen? I'll draw a simple map for you."

"Of course it's good!" Jiang Liushi hurriedly asked the soldier who borrowed paper and pen. The soldier had hesitated for a moment, but after looking at Jiang Zhuying and the others not far away, he still reluctantly gave it to him.

Seeing the old man holding his pen in his dirty hands, the soldier's face suddenly showed a look of disgust.

"I'll draw it for you..." The old man spoke a little slowly, giving people a feeling of not being very good at spirits. His hands were also a little trembling, but when he was drawing the picture, Jiang Liushi was a little surprised.

This "simple map" is really standard, with smooth lines and very regular.

The old man drew very seriously. He drew it for three or four minutes before he drew the road map and handed it to Jiang Liushi: "Give it. You can go directly from this road, it's the closest."

"Okay." Jiang Liushi took the map and thanked, "Thank you! By the way, old man, what did you do at Jinling University before?"

"Teacher," said the old man, "Professor."

Professor... Jiang Liushi was stunned for a moment. Shouldn't this professor be cared for in the military? Seeing that this old man is old and cannot do anything else, he is arranged to go farming.

He probably had a very unsatisfactory life, so he came in and swayed during the break. Judging from the unconcealed dislike of the soldier behind the table, an old man who was useless, should be very unpopular.

"Astronomy." The old man added.

So that's it... Jiang Liushi understood.

If you are a professor of physics and chemistry or engineering, you will naturally be highly valued, but astronomy has become "useless" in the end of the world. Everyone is concerned about how to survive, and who is still paying attention to the knowledge above your head.

This old professor is really unlucky.

"You should be careful, alas, why do you do this kind of thing at this time..." The old man wiped the pen on a cleaner area on his clothes, put it back on the table, and then turned around and prepared to leave.

"Wait a minute, old man." Jiang Liushi stopped him.

The old man turned his head to look at him in confusion, and Jiang Liushi looked at him, feeling that this old man could not move even more. If this continues, how long he can live is a problem.

Jiang Liushi thought about it, took out a bag from his pocket, and handed it to the old man: "You can take this."

This is a bag of jerky meat from mutant beast meat. Jiang Zhuying gave him the portion before, and it was very large, which was much more than what Yang Qingqing and the others had to eat.

However, for Jiang Liushi, who got another mutant dog, this jerky meat is nothing.

Originally, the soldier had lost interest in the dialogue between Jiang Liushi and the old man, and was flipping through a book, but he glanced at him casually and saw Jiang Liushi taking out a bag of mutant beast meat so casually, and he had to give it to the old man!

The old man looked down at the jerky meat, with a hint of desire flashing in his eyes, and he couldn't help swallowing his saliva.

If it weren't for special talents in this camp, they would allocate food according to work. He, a useless old man, naturally had very little food and did not eat well.

He hasn't eaten meat for a long time.

At this time, the soldier couldn't help but speak.
