Venom grenades?

Not only can it produce explosions, but even the venom effect is extremely aggressive to alien beasts?

Since the dungeon came back, all the snow-disaster grenades have been used up, and Su Heng has no AOE attack weapons in his hands.

Dr. Li's research made Su Heng's eyes shine, and he had great expectations for the finished product.

Su Heng: "I don't have a problem here, you can fight the disaster with confidence."

Su Heng not only consolidated the foundation of the shelter, but also set up an electromagnetic defense line on the periphery.

However, Li Sike did not know this.

Li Sike took the initiative to ask about his safety, but it made Su Heng feel a precious touch of humanity.

It may be seen by outsiders that Su Heng's active inquiry was mainly to know whether the experimental platform was safe, or to "urge work" and "check the post" with Dr. Li.

Su Heng was not so ruthless yet, he really just asked about Dr. Li's current situation.

Su Heng: "I'm very safe here, as long as you have the confidence to fight against disasters."

Su Heng: "I also received crude oil and a design drawing of Glock 17, which will be sent to your mailbox later."

Su Heng: "Dr. Li, you don't need to rush things at hand, I'm not in a hurry, please take a rest."

Crude oil cannot be directly put into diesel generators to generate electricity, it must be refined.

Su Heng knew nothing about chemistry, and almost forgot the periodic table of elements.

Whether it is refining crude oil or manufacturing accessories, it is necessary to use the functions of the advanced technology experimental workbench, so it has to be handed over to Dr. Li.

The two have always had a tacit understanding, and neither of them has mentioned the issue of the ownership of the advanced technology experimental workbench, but they both know it well.

If I had to describe it, I would use the boss and the employee to describe it.

Su Heng provided equipment and capital, while Li Sike provided time and technology.

The two are actually in a mutually beneficial relationship.

Li Sike can continuously get technology and equipment from him, and can even improve his own technology level.

According to Dr. Li himself, he has used the battery provided by Su Heng, coupled with his own re-engraving technology, and has also returned to the era of electricity.

Before concluding the conversation, Dr. Lee mailed all the finished items and presented 2 of his homemade tungsten filament light bulbs.

Su Heng: "Okay, thank you."

Li Sike: "It's okay, it's okay, just a little effort, as long as an experimental science student can make this stuff, haha."

After the conversation ended, Su Heng found Yin Yanyan.

Su Heng: "What are you doing?"

Yin Yanyan: "Brother Xiao Su, are you done?"

Yin Yanyan: "I want to send you a message today, but seeing that you are always busy, Xiao Yin didn't dare to send woo woo."

Yin Yanyan: "I'm watching the live broadcast, learning how to cook, Xiao Yin's cooking skills are really bad!"

Learn to cook?

Su Heng felt that before Yin Yanyan was released, she should have been a delicate little princess who did not touch her fingers.

Su Heng: "I think they are all recruiting robots. Have you recruited iron armored labor robots?"

Yin Yanyan: "Huh? Iron armored working robot? Xiao Yin also heard about it."

Yin Yanyan told Su Heng that she had few upgrades on the shelter, but because she was in an excellent location, she only took defensive measures on the only nearby mountain road.

Except for those flying in the sky, no alien beast can pass through her mountain road.

This also led to Yin Yanyan's insufficient shelter level, and the technology was far behind, which could not meet the minimum requirements for opening the recruitment function.

Su Heng: "You can't do this. What if there is an accident?"

Su Heng: "You still need to pay attention to the upgrade of the shelter. In addition to improving safety, you can also improve your own technology, which is very helpful for your survival."

Su Heng: "You can't watch other people use recruited robots to kill alien beasts, and use products of the electrical age to deal with disasters. You have to do everything yourself. Are you still in the stone age?"

Yin Yanyan: "Aiya, is brother Xiao Su caring about Xiao Yin?"

...

It can be understood that way.

However, shelters are not so easy to upgrade.

Relying on his own plug-ins, Su Heng has returned to the electrical age in just over half a month.

In such a tone, Yin Yanyan was warned, somewhat "why not eat minced meat".

Su Heng: "Upgrade the shelter first. There is a recruiting function to recruit as soon as possible. Labor robots are very useful."

Su Heng: "If you encounter any difficulties, you can tell me."

Yin Yanyan: "Yeah!"

Yin Yanyan: "Brother Xiao Su is so annoying to me!"

Su Heng: "Well, let's take a rest. It's not too early. Pay more attention tomorrow."

Yin Yanyan's state is [busy], and Su Heng sent her a message but didn't reply, so she didn't pay much attention.

When everyone was broadcasting live, Kyushu still did not open the live broadcast room, and Lin Wanqing and Zhang Beihai also showed that they were in a [busy] state.

It is worth mentioning that in most of the top-level live broadcast rooms, only some teams have recruited iron armored labor robots.

There is only one reason.

That is, there are too many members of the squad.

There is simply no extra population left for them to recruit.

Can only watch [recruitable 0/1]

And at this time ~lightnovelpub.net~ team with a small number of people will have an advantage, and they can recruit one step ahead and do more things.

"The number of times the food processor didn't work today."

Su Heng purifies the polluted water all the times of the processing instrument, and uses up 5 processing opportunities.

Su Heng stood in the shelter and looked around for a week, thinking about what he had yet to do.

train?

Su Heng's high-intensity work for several days has left him with no energy to train at all. Even if he has perseverance, his physical strength is not enough.

bath?

too lazy to move.

"correct!"

"You can upgrade the security door again!"

The current vault security door has two exits, all of which are stone.

"The next upgrade direction of the shelter is definitely to upgrade towards reinforced concrete."

"The materials currently in hand are not enough to upgrade the entire underground shelter, but it is more than enough to upgrade two security doors."

Su Heng came up with this idea mainly because the current two security doors have no concept of "locking the door" at all.

As long as you find a way and a trick, you can open the door with a push.

It's okay to deal with alien beasts with negative IQs, but it's not good for humans.

Otherwise, he would not have left a disaster snow grenade at the door as a defensive measure.

"It can be regarded as the last insurance for yourself."

"In case the electromagnetic fence is breached, I can still survive in the shelter for a few months."

"There are enough pure hands on hand, there is no need to worry at all."

[Stone Security Door] is upgraded to [Reinforced Concrete Security Door]

With 30 points left in Doomsday Honor, Su Heng chose to use materials to upgrade.

"Confirm upgrade!"
