"It's too dangerous. Once they are found besieged by monsters, they may not come back!" Li Changhe said in a deep voice, "I'll take someone!"

Li Mugang has just won the first place in the trial. Li Changhe has regarded Li Mu as the future and hope of Chengdu fortress. The military attaches importance to the ten boxes of crystal stones, but Li Changhe thinks Li Mu is more important than the ten boxes of crystal stones.

"General Li and General Xu, you are now the highest combat power in Tieshan town. You must sit here to prevent accidents!"

Zhuo Heng shook his head and said.

Li Changhe and Xu Rusong are both vice presidents. They have also made a lot of military achievements in recent years. They also have the rank of brigadier general in the third group army.

But they are not real brigadier generals, but enjoy the treatment of brigadier generals. Real brigadier generals and enjoy the treatment of brigadier generals are two different things.

"When to go!" Li Mu asked directly. Although things are dangerous, someone must do them.

Although Zhuoheng's soldiers are also martial friars, most ordinary soldiers have no products at all, and most of them are yellow level masters. This matter must be protected and helped by the strong.

"After dark, it's almost dark now. Those monsters will certainly find their actions during the day. Although it's dangerous at night, it's not so easy to be found. Only when it's dark can they have a chance!"

Zhuo Heng said.

"How many people are going?" Li Mu nodded slightly and continued to ask.

"There are about three or four thousand anti tank mines left in the warehouse in Tieshan town. This is all the inventory. If possible, I hope these mines can be rearranged!"

"I'm going to send 200 people to follow you. They are responsible for laying mines and you protect them!" Zhuo Heng said.

"There are too many people. If so many people act together, they will be found. We can't protect so many people. We can only go to 100 people at most!"

Li Mu said in a deep voice.

Even if some military experts are selected, plus the remaining martial friars of Wudao University, Li Mu can only gather up 20 or 30 people at most. This manpower is simply impossible to protect 200 people and lay mines at the same time.

Moreover, sending more than 200 people to act together at one time is too easy to be found.

"There are only 100 people. I'll try to let them carry more mines!" Zhuoheng thought about it and thought what Li Mu said was very reasonable. He nodded and said, "then we will start to act after the end of dusk in an hour!"

During the period after dusk, most monsters who like to move during the day have stopped their activities. Monsters who like to move at night have not started their actions. That period of time is the safest time, which is also the experience accumulated for a long time.

"OK, move in an hour!"

Li Mu nodded and walked directly to the barracks. Tieshan town prepared barracks for Li Mu. The barracks are single rooms and officer barracks.

"The big demon in the demon mountain has appeared. We can't place all our hopes on the rescue of Chengdu fortress. After leaving the city, there is the world of monsters. Chengdu may not come easily!"

"I need to do something else, just in case!" When Li Mu entered the barracks, his eyes fell on the crystal box he was carrying.

There are at least hundreds of spars in this box. If all the energy is absorbed by the Star Destroyer, the Star Destroyer can recover a lot of energy and can start more engineering robots.

"These crystal stones are very important to the Chengdu military. Otherwise, they would not pay so much. They want to transport all the crystal stones back. But if everyone dies in Tieshan Town, the third group army can't even get a box of crystal stones. It's a good deal to consume a box of crystal stones and leave one behind!"

"Brain, extract this box of spars!" When Li Mu made a decision, he immediately ordered.

"Yes, master!" The voice of the main brain sounded, and then a faint light appeared centered on Li Mu. When Li Mu opened the box, he saw that the faint brilliance on the crystal stone he was carrying began to dim with the naked eye.

However, in more than ten minutes, the energy of this box of spar was completely extracted.

"This box of spar is waste, but it must be worth it!"

If possible, Li Mu even wants to extract all the other boxes of spars, but he doesn't know what Chengdu fortress is going to do with those spars. If these spars are of great use to the third group army, they will be extracted by him and affect what the third group army has to do.

"Master, the Star Destroyer has been charged. This charging has reached four standard units. At present, the energy of the Star Destroyer is 7.01%, and the energy recovery is more than 5%. The master's authority is upgraded to the second level, and the Star Destroyer repair can be started!"

"The authority has finally reached the second level, which means I can make more weapons!" Li Mu said to himself with joy in his eyes.

"But I didn't expect that this box of crystal stones could equal the energy of two starlight crystals!"

Before, Li Muli used the star crystal to charge the Star Destroyer. One star crystal provided two standard units of energy, making the energy of the Star Destroyer reach 3.1%. Now this box of crystal provides four standard units of energy for the Star Destroyer, which is equivalent to two star crystals.

"With energy, the next step is the resources to make weapons. There are still half an hour!"

Li Mu looked at the time, then immediately came out of the barracks, avoided the sight of others, and quietly entered the warehouse in Tieshan town.

Tieshan town is a mining town. The most important thing in this town is to excavate iron ore. before Li Mu came, the whole town was still working normally, so there were a lot of iron ore in the town. These iron ore would be sent to the steel plant in Chengdu almost twice a week.

There are at least thousands of tons of very high-quality iron ore in front of Li Mu. Li Mu looked at these ores and immediately asked the main brain to start transmitting these ores into the Star Destroyer. As for the reaction of the people in the town to find these ores missing when the battle is over, it is not Li Mu's consideration.

In less than half an hour, Li Mu almost sent all the thousands of tons of iron ore back to the Star Destroyer. After all, it may not be so easy to get these resources next time.

With energy and resources, Star Destroyers can start a large number of Engineering robots to manufacture the weapons Li Mu wants as quickly as possible.

The warehouse was empty. As soon as Li Mu returned to the barracks, the door of the barracks was knocked.

"Major Li, we are ready. Can we start?" The soldier outside knocked on the door and said.

"Get ready to go!"

Li Mu opened the door of the barracks, came out, took a look at the open space in front of the barracks and said.

About 130 people had gathered in the open space in front of the barracks, of which 100 soldiers were all carrying a large box.
