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 big iron gate of the central castle. ◢ With * dream ◢ small * .com

Although the alien can corrode the metal, after the actual killing, it will definitely take time to corrode and open the gate.

In addition to installing the big iron gate, Lu Chao also asked Shan Shun, Zhou Xu and others to work together to knock down all the trees near the castle and move them into the distance. In this way, the view around the castle is relatively wide, and if the alien is close, it can be detected in advance.

When everyone was doing these things, Jiang Xiaoyun had been accompanying Yaya, and Ivan didn't come over to help, but just stood on the corner of the city wall alone, with a cold expression, as if someone owed him three hundred catties of soybeans.

Lu Chao didn't bother to care about him.

I don't have time to leave him alone.

"Coach, with your strength, can you handle two steel worms?" Lu Chao asked Shan Shun when he was busy.

"The strength of this thing is equivalent to the three-turn beast after quenching the bones, if I encounter it, even if there is only one, I will be killed in seconds, let alone two." Shan Shun smiled wryly.

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

"Yes, it's best to kill these two steel worms so that you can return to your former world alive." Lu Chao replied to Zhou Xu.

As for what the mysterious forces will do with these people after the task is completed, Lu Chao is not clear. Answer them in this way, lest they panic and be detrimental to his command.

"Do you have any other stronger places to hide? This castle can't stop the attack of two steel worms, their claws can grab into the cracks in the stones of the city wall, and easily climb the city wall, hunting us easily. Shan Shun asked Lu Chao.

"In the center of the central castle is an all-alloy hut, about twenty square meters." Lu Chao replied to Shan Shun. He didn't want to mention his house for a while, because his house was about the same as this alloy hut in the castle. If the alloy hut can't stop it, his house can't stop it either.

These people don't know how they were 'hijacked' to the spaceship, and if they knew that Lu Chao lived here, they would have more questions to ask Lu Chao.

Now is clearly not the time to answer the question '100,000 whys'.

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

The alloy classification level in the supermarket was the same as that of the Gaowu world, and Shan Shun could see that the hut was made of D-grade alloy, and he knew that the alloys of grade and below could not resist the attack of steel worms at all.

When the steel worm first appeared in the Gaowu world, it was called the steel worm because it devoured the steel buildings of the human colony and grew into steel and iron bones. In fact, this thing eats not only steel, but other metals as well, and the more metal it devours, the stronger the body shell.

After hunting the steel worm, the rice people of the Gaowu world found a lot of inspiration from the composition of the steel worm's shell, so that the alloy technology of the rice people has always been ahead of other countries, which has greatly reversed the trade deficit between the rice country and China in the Gaowu world.

There are also rumors that Mi Guo is using the genes of this steel worm to create a large number of biochemical warriors.

Shan Shun didn't care much about these things before, but he had only heard about them.

……

"What do we do next? Is there a new hint from that voice in your head? ”

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

"There are no new hints, all we need to do is try to survive, survive 24 hours, and then kill those two steel worms." Lu Chao replied to Shan Shun.

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

"Thank you, little beauty!" Shan Shun touched Yaya's head and thanked her.

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

Ivan glanced at Yaya, his body trembled slightly, and after a while, he squatted down, reached out and took the biscuit from Yaya's hand, his cold eyes showed a little tenderness.

"Yaya, do you know who I am?" Ivan opened his mouth to the maid.

The girl took two steps back, looking a little scared, but her eyes were still fixed on 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...... Mother. The girl opened her mouth at Ivan.

After returning to the supermarket these days and getting electricity, Lu Chao often used his mobile phone to show Yaya the photos of Yili, and told her that the person in the photo was her mother, and Yaya obviously mistook Ivan for the person in the photo.

"What are you calling me?" Ivan was a little flustered.

"Mom." Yaya shouted again timidly, and then ran back to Jiang Xiaoyun's side, looking at Ivan from a distance.

Ivan's tears instantly welled up in his eyes, and he quickly stood up and turned outside the city walls.

When Jiang Xiaoyun saw this scene, her face was confused, she really didn't understand why Yaya called Ivan like this.

Ivan and Lu Chao...... What relationship?

"This castle can't protect us, the steel worm is invincible to us in this environment, and hiding here is waiting for death." Shan Shun continued to talk to Lu Chao.

"What the coach said makes sense, if there are really two steel worms, we must escape, the farther away the better, here is really waiting for death." Zhou Xu, who had just walked on the city wall, also opened his mouth, and Shan Yao followed him up the city wall together.

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

Two tasks, none of which are easy to complete.

Keeping these five people safe?

He didn't have the ability to do that.

Kill the two-headed alien?

It's even more fantastical.

The traps he had used against the wolves were useless against these aliens.

The weapon in his hand was only a handful of bullets, and the firearm had long proven ineffective against Xenomorphs.

The power of the two loose thunderbolts is also very limited, and even the cannonballs can't kill the aliens, so don't waste this effort.

Not to mention that I don't know where to bury the thunder, the alien may just walk through the canopy without going to the ground.

In addition, with the extremely fast speed of the alien, it is easy to get out after stepping on the loose hair thunder.

"I reckon there's a high-tech weapon in the spaceship that can easily kill those two steel worms." Shan Yao opened his mouth and made a suggestion.
