Xu Xin first made ten power grids, each one meter apart, and connected together they were ten meters apart.

He swung down from the tree house and arrived at a location fifty meters away from the tree house.

Judging from the current situation, plants can still be planted within 50 meters, but plants cannot grow beyond 50 meters. This can just enclose the area that can be planted.

Xu Xin placed ten power grids side by side here.

Although the power grid had only penetrated less than ten centimeters into the ground, it was firmly fixed. With Xu Xin's current strength, he could not move it even an inch.

I wonder if this barbed wire fence is still rooted in the ground.

Xu Xin raised his fist and hit the power grid with all his strength.

The electric grid only trembled slightly and deformed slightly, but his fist was hurt by the iron net.

"This strength is enough." Xu Xin covered her fists and nodded with satisfaction.

He looked toward the treehouse.

This is fifty meters away from the tree house. If you are using wires to connect the generator and battery in the tree house, you need to pull the wires down from the tree house and then come here.

The tree house is ten meters high, which means that it requires 60 meters of wires and six copper blocks. And such long wires are too easily affected.

Let's make another generator and battery here, specifically for protecting the grid and traps.

It is a good idea to separate the power supply for the protective grid and traps from the power supply to the house.

After all, if the external power grid is attacked and too much power is consumed, it will easily lead to insufficient power in the tree house.

This is not good.

It's better to separate.

Xu Xin returned to the tree house.

Looking at the 11 blue-grade copper ores left in his hand, Xu Xin tried to make a blue-grade coal generator, but was unable to make it.

The coal generator requires thirty iron blocks and five copper blocks, which requires a lot of materials.

The principle is the same as that of furnaces and fireplaces. With so many materials, it is impossible to upgrade the whole thing to blue level with just one blue-level material. For such a large object, all the materials need to be blue-level.

Therefore, a blue-level coal generator requires thirty iron blocks (blue) and five copper blocks (blue), which is really too much.

To be honest, it is not impossible for Li Wenxi to get thirty blue-level iron nuggets, but at present, it is not necessary at all.

At least, the green-level coal generator alone is more than enough to supply the life and defense power of his own treehouse. Blue-level or higher-level generators are probably prepared for groups.

After making another coal generator and a blue-level battery, Xu Xin returned to the ten barbed wire fences.

The coal generator and battery were placed inside the barbed wire fence, and Xu Xin used the remaining wires to connect the generator, battery, and barbed wire fence.

Although there are ten wire meshes, the wire only needs to be connected to one of them, and the electricity can act on all the wire meshes.

Xu Xin threw two hundred pieces of coal into the new coal generator.

There is no other way. I have more than 50,000 pieces of coal in my hand, and two hundred pieces is really nothing.

The coal generator began to roar and vibrate, and then the charge in the battery began to rise.

The entire power grid, after the engine is started, will start to have current flash through it from time to time, and will also make a sizzling sound.

The somewhat deformed power grid that he had just hit slowly returned to its original state after being powered on.

It can actually recover automatically! Strong!

Although it was mentioned in the introduction that the power grid hurts enemy units, Xu Xin would never dare to touch a power grid like this.

Unfortunately, there are no hostile units around now, so we can't test the power grid.

If it works, then keep doing it.

He returned to the treehouse and sent a message to Li Wenxi, saying that he wanted 1,000 green-grade iron blocks.

Li Wenxi naturally knew that he was going to surround the high-voltage power grid, so she immediately sent it to him readily, and then sent him a message: "I have so many metal blocks, why don't you come and mine with me?"

Xu Xin got the iron block and while making the barbed wire fence, she replied: "Definitely next time!"

Coco, who had just eaten and drank enough, ran to the second floor to find him and climbed onto his shoulder.

"I am full?"

"Hey!"

Ten minutes later.

Xu Xin looked at the barbed wire fence surrounding it and nodded with satisfaction.

He already knew that this high-voltage iron grid would not release high-voltage electricity to his own units or neutral units, because Coco had just climbed up along the barbed wire while he was not paying attention.

Today's high-voltage power grid has stabilized, and there will no longer be flashes of current and making sounds like it was just now. The current power grid looks like an ordinary barbed wire fence.

"Keke, come down, don't climb up." Xu Xin said to Keke, who was about to touch the tangled wires on the high-voltage power grid.

"Hey!" Keke touched the random wires with his little paws, probably because he was stuck. He screamed in pain, immediately turned around and crawled down, climbed down twice, and threw himself into Xu Xin's arms, "Hey

…”

Xu Xin hugged Coco, took a deep breath, and reached out to touch the high-voltage power grid.

The moment his fingertips touched, he felt a trace of electricity blooming in his fingertips, and he immediately retracted his hand.

However, the high-voltage power grid did not cause any harm to him, it just made his fingertips hurt like static electricity.

[Iron wire high-voltage grid (green): When an enemy unit touches it, it will consume the power in the battery and release high-voltage electricity, crackling, crackling, and smelling like barbecue! It is powered on and will not cause damage to friendly and neutral units, but will cause damage to enemies.

Square units caused tons of damage!]

Seeing this introduction, Xu Xin was completely relieved.

He opened a barbed wire gate that could be opened and closed around the power grid in the four directions, southeast and northwest, to facilitate his entry and exit.

The coordinates were just enclosed by him inside the high-voltage power grid. In this way, the person who was teleported would have the dual protection of the plant heart and the high-voltage power grid, and would not have to worry about being in bad condition.

After doing this, Xu Xin returned to his newly installed generator and battery, and built a small wooden house with a steel frame and logs to surround the two facilities.

Well, that's good, so you don't have to worry about wind and rain.

Of course, if there is exaggerated weather like the rainy season, or if a giant beast attacks, this cabin will definitely not be saved, but by that time, the high-voltage power grid will be of no use, and external generators and batteries will not matter.

At that point, it’s time to protect the treehouse.

After doing this, Xu Xin returned to the tree house.

He directly sent a voice message to Ji Chaoyang and was immediately hung up on.

The other person sent a private message: "We'll wait until we get back to the treehouse in the evening, I'll be outside."

This guy, disaster is coming tomorrow, is he out exploring at this time?

Xu Xin shook his head, confused, but considering his character, he would definitely not do anything reckless. Could it be that he discovered something in the prophecy.

Xu Xin told them about the power grid directly in [Explorer] and asked them who is in the tree house now.

Wang Lei: "Damn it! High-voltage power grid? It sounds so safe!"

Zhao Xiaochuan: "Brother Xin is awesome! I'm still worried about whether I will be in a hurry tomorrow just relying on the control panel to fight against the beast tide. The high-voltage power grid will come! I'll go back to the tree house now!"

Wen Guixin: "Electric water heater and water pump? It sounds very good! I'm still outside now, I can only wait until I go back in the evening."

Xu Xin: "If you don't have a plant heart, go back to the treehouse first and configure the power grid first."

Qi Xuefei: "I'm in the tree house now."

This was a private message sent to him by Qin Yunlong.

Qin Yunlong: "Xu Xin, was your copper mine discovered underwater? How deep was it?"

He just mentioned the matter of copper mines. Qin Yunlong was sensitive to underwater resources, so he immediately sent him a private message to ask.

Xu Xin immediately replied: "About forty meters, is there no problem for you? Have you not found similar ores?"

It would be great if copper mines could also be discovered in Qin Yunlong's area.

Qin Yunlong: "About forty meters...your diving ability is also pretty good."

"Didn't you say before that normal people can dive below a hundred meters?" Xu Xin said jokingly, thinking of what Qin Yunlong had said before.

"Haha, I didn't want to expose my ability at that time. Now that everyone has the ability, it doesn't matter whether I expose it or not." Qin Yunlong replied.

"So, is there this kind of green ore under the water over there?"

Qin Yunlong: "I feel ashamed to say that I have indeed seen ore, but it is not green, and...it is guarded by underwater beasts, so I don't dare to mine it."

"Underwater beast?" The corners of Xu Xin's eyes trembled, and he immediately thought of the giant anaconda in the middle of the lake.

Are there similar monsters on Qin Yunlong's side?

"There is a small lake near the tree house of my brother and I. It is not big, but it is very deep and has many caves. There are many dangers in it, and there are even very powerful mutant creatures. We dare not let go to explore, but it is true

The ore we have seen should not be copper ore, at least not the green ore you mentioned."

Well, it seems that copper ore should be used sparingly for the time being.

Xu Xin could only propose that he make a purple-level weapon, and provide him with mutant potions to enhance his physical abilities, so he could figure out which ores were which as soon as possible.
