Zhang Tuohai walked around the tower with his hands on his back. The whole tower was searched clean.

The useful machinery was removed by lilina and installed in the advanced manufacturing factory. Even the useless garbage was converted into metal ingots and metal parts by Zhang Tuohai's resource recovery steam self-propelled machinery.

Even if it cannot be transformed, it is thrown into the fertilizer making machine to make fertilizer.

Anyway, all the things that could be taken away were not left at all. They were all searched.

After completing the move, lilina hid in her study. She had a lot to say to Lilith.

Zhang Tuohai didn't doubt him either. He went back to the car and looked through the pamphlet about the use of Yuanshi given to him by lilina.

According to the contents of the pamphlet, Zhang Tuohai learned that these source stones appeared before the war. She once found traces of using source stones in some pre war materials.

It seems that the source rock is not produced in the world, but brought to the world by some meteorites.

Source stone is a mineral rich in energy. When the energy is slowly extracted, it can maintain the operation of the human body, recover the injury, nourish life and so on.

However, if the energy inside the source stone is violently excited in some ways, it will cause a violent explosion, just like what was done in the holy mountain.

In addition, Yuanshi has some wonderful uses, but Lilith writes a guess at the end of the booklet.

If it is covered with the radiation of the source rock for a long time, some machines will produce some kind of life reaction.

This conjecture was obtained after Lilith combined some pre war data and conducted comprehensive research.

However, Lilith's resources are really limited. She can only leave this conjecture on paper and can't carry out effective experiments.

"This thing is the source of fire?" Zhang Tuohai looked at the source stone in his hand and suddenly thought of a science fiction film.

"If this conjecture is true, will all the machines in my car become Transformers after a long time? Even the infantry chariot has become mechanical life? If so, it will be great fun."

Zhang Tuohai thought.

If they are in the same heart as themselves, it's good to say that if they rebel like Decepticons, they may have to stop cooking immediately.

However, Zhang Tuohai thought about it and put his heart back.

Lilina used the source stone to continue her life for several years, and Lilith also used the source stone for several years. If this conjecture is true, must lilina's Brass coffin be the first to change?

However, now the brass coffin is still well placed in Lilith's study as an ornament, without any sign of variation.

Moreover, even if this speculation is true, it is estimated that it will take a long time to radiate.

Zhang Tuohai himself may not be able to live to that time. It's really unnecessary to hold this heart.

Thinking of this, Zhang Tuohai put the source stone away properly, and the pamphlet was casually filled into the stove.

He knows how to use this thing. There's no need to stay and tell others.

After dealing with these things, Zhang Tuohai looked at the time. It was 6:00 a.m. on the seventh day.

However, the game system still hasn't released an announcement. It seems that it won't release the news until the last time arrives.

Zhang Tuohai looked at the regional channel again, and dozens of death messages came out.

The cause of death is still magma, poison gas and so on.

It seems that the collapse of the earth didn't stop until last night.

This is a lasting endurance challenge for many players.

If there are other people on the same bus who can change shifts, it's OK. If not, I'm afraid I can only rely on myself.

I'm afraid many people haven't slept since yesterday.

Zhang Tuohai thought for a moment, decisively woke up Wangcai and hung up a large number of espresso and milk tea.

After hanging up the list, Zhang Tuohai said in the channel, "milk tea and espresso are newly launched. You need to hurry up."

"Finally there's coffee. I've been cooking for two days. Now I'm driving with a match on my eyelids. I'm about to lose my grip."

"Milk tea is great. My mood value is about to reach the bottom. I can finally have milk tea to recover."

"Why are coffee and milk tea so expensive? Has the price increased more than ten times?"

Someone was surprised at the price.

At this time, Zhang Tuohai has set the price of a milk tea to 15 units of grade 3 manufacturing materials or 150 units of grade 2 materials.

It's 15 times as much as before.

It can be said to be a sky high price.

"Isn't it too expensive? You're made of milk tea gold? You want 15 units of level 3 material?"

Someone complained.

"Man, there's no milk tea now. It's all from the greenhouse. You're too expensive, and I'm too expensive. At this price, I'm only looking at your pity to sell a batch with tears. Otherwise, it's better for me to drink it slowly. Anyway, it's so much. It's enough to sell out."

Zhang Tuohai said.

In his eyes, many people in the regional channel may not survive today. In that case, try your best to squeeze out their last value and become the soil for their own survival.

Sure enough, those people said it was too expensive, but their bodies were very honest. The milk tea and coffee hung up were quickly robbed.

Subsequently, Zhang Tuohai contacted Cang Xiaokong and asked her to contact the buyer and go out for milk tea at the price of 20 units per cup.

Strive to maximize profits.

"Boss, I'm afraid the player doesn't have much material. When you replaced it a few days ago, you exchanged a lot. There are no boxes in the world, and the output of manufacturing materials is less. Now most of those camps have been captured, and there's no chance to supplement them." Cang Xiaokong said.

"Then take other things instead. We need weapons, medicine, food and oil. Anyway, the price difference is not too much."

Zhang Tuohai said.

During this period, most players who need to buy a large number of mood supplement items have no future. Zhang Tuohai doesn't mind scraping harder.

"I see." Cang Xiaokong nodded and turned to contact his customers.

It has to be said that Cang Xiaokong's communication ability is really strong, and soon brought more than 100 orders for Zhang Tuohai.

You know, the total number of players remaining in the regional channel is only 532.

After several rounds of large-scale player deaths, Cang Xiaokong's trading face can still cover one fifth of the player group.

It can be seen that Cang Xiaokong's ability is strong.

Zhang Tuohai silently raised Cang Xiaokong's rating to a level that he had no choice but to give up.

At this level, it is basically only one step away from friends.

While Zhang Tuohai was dealing with the transaction, Zhao wanwan suddenly sent a private letter: "brother Zhang, the ground seam is spreading!"
