After everyone entered the castle, Lu Chao quickly returned home, took tools and a pack of screws, and asked Shan Shun and others to help install the city wall and the large iron gate of the central castle.

Although the alien shape can corrode metal, after it actually comes, it will definitely take time to corrode and open the door.

In addition to installing the large iron gate, Lu Chao also asked Shan Shun, Zhou Xu and others to turn all the trees near the castle to the distance. In this way, the view near the castle will be wider, and if the aliens are close to it, you can also discover them in advance.

While everyone was doing these things, Jiang Xiaoyun kept accompanying Yaya. Yifan did not come to help, but stood alone on the corner of the city wall with a cold expression on his face, as if someone owed him three hundred kilograms of soybeans.

Lu Chao was too lazy to care about him.

I don't have time to care about him.

"Coach, can you get two steel insects with your strength?" Lu Chao asked Shan Shun while he was busy.

"This thing is equivalent to the three-turn strange beast after bone quenching. If I encounter it, even if there is only one, I will be killed instantly, let alone two." Shan Shun smiled bitterly.

"Are you really sure that our mission is to survive for 24 hours under the attack of these two steel insects?" Zhou Xu confirmed to Lu Chao.

"Yes, it's best to kill these two steel insects so that you can return to the world you were in alive." Lu Chao answered Zhou Xu.

As for how the mysterious power will deal with these people after the mission is completed, Lu Chao is not clear. He answered them like this so that they would not feel panic, which would be detrimental to his command.

"Do you have other more solid places to hide? This castle cannot stop the attack of two steel insects at all. Their claws can be grabbed into the cracks of the stones in the city wall, easily climbing up the city wall, and hunting us easily." Shan Shun asked Lu Chao.

"There is a fully alloyed hut in the center of the Central Castle, which looks about twenty square meters." Lu Chao answered Shan Shun. He didn't want to mention his house for the time being, because his house is similar to the alloy hut in the castle. If the alloy hut cannot be stopped, his house will also be unable to be stopped.

These people didn't know how they were "hijacked" to the spacecraft. If they knew that Lu Chao lived here, they would ask Lu Chao for more questions.

Now is obviously not the time to answer ‘100,000 why’.

After checking the alloy hut in person, Shan Shun was very disappointed.

The alloy classification level in the supermarket is consistent with that of the Gaowu World. Shan Shun saw that the hut was made of D-level alloys, and he knew that alloys C-level and below could not resist the attacks of steel insects at all.

When steel insects first appeared in the Gaowu world, they were called steel insects because they devoured steel buildings in human colonies and grew into steel bars and bones. In fact, this thing not only ate steel, but also other metals. The more metal species it swallows, the stronger the body shell.

After hunting steel insects, the Americans in Gaowu World found a lot of inspiration from the shell components of steel insects, making the Americans' alloy technology always ahead of other countries, greatly reversing the US's trade deficit with China in Gaowu World.

There are also rumors that the United States is using the genes of this steel insect to create a large number of biochemical warriors.

Shan Shun was not very concerned about these things before, but had just heard of them.

...

"What should we do next? Is there any new hint in the voice in your mind?"

Standing on the city wall and looking at the woods that had been cleared dozens of meters around the castle, Shan Shun asked Lu Chao.

"There is no new tip. All we need to do is to survive, live for 24 hours, and then kill the two steel insects." Lu Chao answered Shan Shun.

While the two were talking, Yaya ran over and handed a biscuit to Lu Chao and the other to Shan Shun. The biscuit was brought down by Jiang Xiaoyun from the spaceship and asked her to distribute it to everyone.

"Little beauty, thank you!" Shan Shun touched Yaya's head and expressed his gratitude to her.

Yaya grinned at Shan Shun, and then ran to leave the spaceship, and stood alone in the corner of the city wall, next to Ivan, who had not spoken to anyone, and handed a biscuit to Ivan.

Yifan glanced at Yaya and his body trembled slightly. After a while, he squatted down and reached out to take the biscuits in Yaya's hand. His cold eyes showed a little gentleness.

"Yaya, do you know who I am?" Yifan spoke to Yaya.

Yaya took two steps back, looking a little scared, but her eyes were still staring at Ivan's face.

Ivan's expression was a little painful, as if he wanted to say something, but he didn't say it for a long time.

"Mom...Mom." Yaya spoke to Yifan.

After returning to the supermarket these days, Lu Chao often showed Yili's photos with his mobile phone and told her that the person in the photo was his mother. Yaya obviously mistakenly mistakenly regarded Yifan as the person in the photo.

"What are you calling me?" Yifan was a little stunned.

"Mom." Yaya shouted again timidly, then ran back to Jiang Xiaoyun and looked at Yifan from a distance.

Ivan's tears instantly poured out of his eyes, and he quickly stood up and turned outside the city wall.

When Jiang Xiaoyun saw this scene, she looked confused. She really didn't understand why Yaya called Yifan like this.

What is the relationship between Yifan and Lu Chao?

"This castle cannot protect us. Steelworms are simply invincible to us in this environment. Hiding here is just waiting to die." Shan Shun continued to say to Lu Chao.

"What the coach said makes sense. If there are really two steel insects, we must escape. The farther the better. We are really waiting to die here." Zhou Xu, who had just walked up to the city wall, also spoke, and Shan Yao followed him up the city wall together.

"Do you have a better way?" Lu Chao had a headache.

None of the two tasks is easy to complete.

Protect the safety of these five people?

He has no such ability at all.

Kill two aliens?

It's even more a fantasy.

The traps he had used to deal with wild wolves to deal with these aliens were useless.

The weapons in his hand were only a small number of bullets, and the guns had long proved that they were ineffective against aliens.

The power of the two thunderbolts is very limited. Even the aliens cannot even be killed by shells, so don’t waste this effort.

Not to mention that you don’t know where to bury the thunder. The alien might just walk through the tree canopy and never fall into the ground.

In addition, with the extremely fast speed of the alien, you can easily escape after stepping on the thunder and launching a mine.
