Big camphor tree base.

In the morning of this day, my second uncle also used the radio to inform everyone in the base about the thunderstorm disaster.

However, it seems that the people in the base have experienced too many natural disasters, and after being shocked for a while, they continued to do what they were doing.

Including those cooperating personnel, they all know how strong the protection of the Da Zhangshu base is.

After notifying everyone, it actually promoted the enthusiasm of many construction personnel.

After the broadcast, some construction workers also discussed privately:

"I asked why we suddenly stopped building the separation wall and turned to heightening the wall. It turned out to be because of natural disasters."

"This thunderstorm natural disaster sounds weird. I don't know what it will be like..."

"I told you two to stop chatting. We've run out of cement. Go and push it over quickly."

...

Oil City.

Two helicopters landed.

Xiao Jun, Ju Tianrui, Lao Yi and others quickly came out to greet them.

The man who led the way down from the helicopter was Li Yu. He came here to inspect the preparations for the trading market.

When this inspection is completed and a natural disaster breaks out later, he will no longer be able to come out of the base, nor will he be able to come out of the headquarters base.

"City Lord."

"City Lord."

"City Lord."

Ju Tianrui and others gathered around Li Yu.

"Um."

Li Yu was wearing black sunglasses, took them off, looked at Ju Tianrui and asked:

"When I was on the road just now, you said that Mr. Tiger didn't plan to come over?"

Just an hour ago, Ju Tianrui waited for Master Hu's answer.

Mr. Hu still plans to stay in the Southern Paradise, because there are too many things here that he cannot take away, and he is worried about being occupied by others.

Ju Tianrui looked unnatural, shook his head and said:

"Yes, he said not to bother us, and also wanted to thank you."

Li Yu frowned. He had been to Southern Paradise to understand the defensive strength there.

Although it's not bad, it doesn't have enough power to support mobile knives like the one in Oil City, and there's no oil array to burn zombies.

It is even more impossible to have three layers of mobile knives like the Da Zhangshu Base.

Also has great firepower.

If you stick to the southern paradise, it is very likely that the zombies will break through and fall.

But after all, it is just a strategic alliance. Having reminded and inviting them is already the most benevolent and righteous thing to do.

Since he's not coming, I wouldn't go and invite him myself.

Not necessary.

"Since they won't come, forget it and let them seek their own happiness..."

Before he finished speaking, Xiao Jun said awkwardly:

"City Lord, can I apply to fly a helicopter and take Ma Yingxue there to talk to Master Hu in person?"

As soon as he said this, Li Yu frowned even more tightly.

This guy is too caring...

But after he saw Ma Yingxue next to Xiao Jun, he suddenly realized.

After thinking for a while he said:

"Okay, go and come back quickly. I'll ask He Ma to take you there."

After saying that, he walked towards the outside of Oil City.

"Thank you City Lord!" Ma Yingxue and Xiao Jun said in unison as they looked at Li Yu's back.

Li Yu did not look back, and was followed by Ju Tianrui, Dongtai, Lao Yi, Li Gang, Li Tie and dozens of others.

A group of people walked out of the gate of Oil City in a grand manner.

"City Lord, the trading market has been built to 16 meters, and it is expected that it will be built to 20 meters in another week." Ju Tianrui was always half a step behind Li Yu, while talking about the construction progress of the trading market.

"Well, what about the infrastructure buildings in the trading market?" When Li Yu walked out of the oil city gate, he synchronized with the two guards on duty at the gate and nodded slightly.

Ju Tianrui quickly replied: "Thousands of square meters have been built, with a total of thirteen simple houses, and construction is still ongoing."

"Where's the mobile gate knife, has it been installed?" Li Yu asked another question.

The sun was strong and dazzling, so he put on his sunglasses again while talking.

Ju Tianrui wiped the sweat from his forehead, maybe it was because a storm was coming.

The closer to the time of thunderstorm disaster, the hotter and muggier the air becomes.

After standing in the sun for less than ten minutes, sweat continued to break out on my forehead.

"The installation has been completed a long time ago. In addition, the oil array outside the trading market has also been completed. The oil array passes through the trading market through underground pipelines and leads directly to the outside."

"If you want to shut down the oil array, you can control the switch in the Oil City to cut off the flow of oil."

Li Yu nodded, and two words came out of his mouth: "Not bad."

It is indeed good. In such a short period of time, such a long wall can be built to a height of 16 meters, and the oil array and mobile gate knives are fully installed.

Then, he continued to ask:

"What about the lightning protection conductive system? This is the key point. I have seen it with you in the radio station. This system must be installed in Oil City and the trading market wall currently being built, as well as in some relatively tall buildings in the city.

"

In his previous life, he had witnessed thunderstorms and natural disasters with his own eyes.

Thunder and lightning flashed.

The silver snake dances wildly.

Dense lightning continued to strike tall buildings and trees.

The probability of indirect lightning strikes and internal surges is high, and most of the damage to electrical equipment is related to them. Therefore, the focus of power supply surge prevention is to absorb and suppress this part of the surge energy.

Upon hearing Li Yu's question about the lightning protection conductive system, Ju Tianrui quickly pulled someone out from the crowd behind him.

"There should be no problem. I'll let him talk to you."

He is not a professional, so he doesn't know much about electricity issues.

A few days ago, after he cried a lot to Li Yu, Li Yu sent dozens of additional experts from the northern border.

Among them are power experts.

A man with messy hair was pulled out and was a little nervous when he saw Li Yu looking at him.

He opened his mouth and said:

"Dear City Lord, my name is Dai Dongdong. Now I will report to you the lightning protection and conductive system in Oil City and the trading market. After careful observation, I have formulated and implemented a system plan that is most suitable for Oil City..."

Li Yu's forehead is full of black lines.

How about playing?

I waited quietly for him to talk a lot, but didn't say a single actual word.

Do I look idle?

He looked at the old Dong who came with him with a cold face and said:

"Old Dong, you go with him to check and see how the lightning protection and conductive system here is built!"

Old Dong stroked his hair, which was the last bit of his stubbornness.

"yes!"

He walked up to Dai Dongdong and asked directly:

"How many layers of lightning protection and surge protection are there? Also, what is the capacity of the power surge protector you use?...."

.....

Li Yu, on the other hand, ignored the dispatched power expert. Ju Tianrui, who was next to him, looked extremely embarrassed and followed Li Yu to inspect the trading market without saying a word.

Li Yu looked at the construction workers who were busy doing construction work. Compared with the last time he was here, the trading market has undergone earth-shaking changes.

Walking to the simple residence that was being built, Li Yu stood outside and looked around. There were no doors or windows inside, and it was just a blank.

Ju Tianrui next to him explained:

"The city lord is rushing forward now, so there is no decoration inside. In the future, there may be..."

Li Yu waved his hand and said:

"It's not important. There's no need for decoration or anything like that. It just needs to be habitable."

"Oh, okay."
