"To prevent them from escaping, of course, one line has to be used!"

Thinking of the purpose of doing this at that time, Xiao Han continued to explain: "Even if all of them are electrocuted, I can still buy them again, but if they are allowed to escape, it will be a big trouble!"

"I understand, I should do this."

Ding Yi touched his chin and thought for a while, and continued with a smile: "If possible, the voltage of the alloy fence should continue to increase."

"As for the current situation where these blood-shaped rats die, it is not impossible to solve it."

"At that time, we can add a layer of power grid with a lower voltage under the alloy fence. If they want to fly up, they will first contact the low-voltage grid."

"You can tell by experimenting a few more times that the voltage can only be corona and will not be electrocuted."

Squeak! Squeak! Squeak!

At this moment, the voltage of the alloy fence finally dropped. The blood-patterned rat that was still flying up was not instantly electrocuted, holding the R1 alloy fence and biting it wildly.

But although their teeth are very sharp, it is still impossible to bite off R1 alloy with a human-grade first-class strength.

Without the strength of the fifth grade of the mortal level, these blood-patterned rats can only stay in the small room of crystal rock below forever.

Crack!

Listening to the sound of biting in my ears, Xiao Han still felt a little regretful.

In just one or two minutes, more than 100 of these void blood-patterned rats who were not afraid of death were electrocuted, and some drawings, books, seeds and other things were also exploded inside.

The loss is not huge. He can still accept more than 100 crystals of the fifth grade of the mortal level. After all, before he started doing it, he had already guessed that this would not be easy.

This situation is completely expected now.

As for what happened next, we need to try it over and over again. The remaining Void Blood-Secret Rats here may not be left in the end even fifty.

Because they are very wild, many of them cannot adapt to such a life after being kept in captivity, and those with bad tempers will eventually die.

What they need to do now is to select the Void Blood-Secret Rat that can adapt to this kind of life through artificial means.

Without caring about those who were already dead, Xiao Han turned to look at Ding Yi and said with a smile: "Since you already have a way, I'm very relieved to leave the matter here to you."

"We have to stay in this level 2 resource area in the future, so I'll go and see the upcoming battle on the level 2 resource island."

"Well, I should know more."

There is actually nothing here now. The rest is water-melting skills. Ding Yi also understood Xiao Han's thoughts and said with a smile: "Then go quickly. If you have the chance, we might be fishermen."

"Okay, then I'll leave first."

Without saying anything more, Xiao Han turned around and walked quickly towards the ground. As for the rest of the things here, Ding Yi might do better than him.

A few minutes later, Xiao Han, who had left the dungeon, opened the storage space and took out the single-person aircraft and carried it on his back.

With the howling sound, he quickly flew towards the observatory.

He was still very curious about what would happen on the Level 2 Resource Island, and wanted to know how many powerful islands there are in this area.

"Sir, you are here!"

As soon as he flew close to the observatory, Xue Bin and others on duty made way out, and Xiao Han controlled the single-person aircraft and slowly landed.

At this time, the observatory was much different from three months ago.

First, at the edge of the observatory, sixteen telescopes with a length of more than three meters were installed, and the diameter of the end was more than twenty centimeters.

This is Qin Yongxing’s research result over the past three months and is named as the astronomical telescope.

The extreme observation distance is more than 30,000 kilometers, but if you want to see clearly what is happening on the island, the distance must be closer to within 10,000 kilometers.

Originally, he wanted to sell the sales rights of this thing to the fox girl Ruoxiang, hoping to make a big profit from it.

But unexpectedly, this kind of telescope has been sold in this void, and its observation distance has even reached 80,000 kilometers, which is more than twice as high as the astronomical telescope.

However, this kind of telescope is a high-end equipment and is very expensive. Generally, it can only be purchased in 5-level towns.

His level is not high enough, so he has never heard of this.

There are better races that can make this kind of telescope, but there are only two best observation effects, one is the mechanical race and the other is the goblin race.

However, after the goblin tribe is created, it can only be sold within the race. Once the mechanical tribe finds that they rob the market, it will attract crazy revenge.

There are no hidden shields at level 5. Once targeted, all goblin islands that reach this level will be very uncomfortable.

Upon hearing this news, Xiao Han immediately lost the intention of promoting the astronomical telescope. At least he was not going to do this until his strength could not fight against the mechanical tribe.

Over the past period of time, there have been many technological fruits produced on the technology tree, but there are really few technologies that can earn a lot of profits.

As for the call device Bass is currently researching, among high-level goblins and mechanical races, there are already finished products. If you want to buy it, the price is very expensive.

More importantly, the things I bought are in the back door, and it is easy to deal with other alien races. If you encounter goblins or mechanical races, this kind of call device can be paralyzed instantly.

Therefore, it is best to study this kind of thing yourself to be reliable.

After looking at the dozen astronomical telescopes around him depressedly, Xiao Han became more and more eager for the corpses of high-level goblins and mechanical tribes.

Only by obtaining such a corpse can the Cold Island usher in a leap forward development.

However, it is useless to think so much now. You still have to take good care of your eyes. After glanced at Xue Bin beside you, Xiao Han asked directly: "Which direction is the level 2 resource island you mentioned?"

"Sir, in the northeast."

Hearing this answer, Xiao Han did not hesitate and immediately came to the corresponding telescope next to the corresponding location.

A place six thousand kilometers away cannot be seen with an ordinary telescope, and only knows that there is an island there.

As for what island it is, how big it is, what race it lives on, etc., it is impossible to know.

But the astronomical telescope is different, and you can even see what is happening above at this distance.

Resting your eyes against the observation port, the picture near the Level 2 Resource Island immediately appeared in front of you.

"Oh, how long has it been, so many islands appeared!"

The picture is very wonderful, he can see an island with a diameter of about twenty kilometers, and islands are flying towards it around him.
Chapter completed!
