"That's exactly what happened!"

Although he had this kind of guess in his heart after entering the city, Xiao Han was still stunned when he saw the light filament connecting Godot, Ling Yi and the others.

Because the people connected by these filaments were all blacksmiths above level 1, and the two who had just entered the blacksmith shop and were responsible for smelting ore did not have a filament to connect them.

"Could it be that the hundreds of zombies outside the city were also blacksmiths when they were alive?" Xiao Han frowned and pondered, but then vetoed: "No, it should not only be a blacksmith, it may be an architect, it may be a planter, and it may even be a pharmacist. ”

"The people connected by these filaments should all know some technology, and ordinary people should not be attracted to these filaments."

Turning his gaze to the direction of the cellar, Xiao Han could guess that the remaining few filaments of light should be connected to Gu Ling, Torge, Su Mei and others.

"But these filaments are connected to people with technology, what do they want to express?" Frowning, he couldn't figure it out.

Walking out of the ironsmith shop, he pressed the white button again, and after the light screen appeared, Xiao Han quickly clicked to the technology tree, but found that at this time, there was an additional icon for storing the logo at the root of the technology tree.

"What does this mean, is it ......" His eyes flashed, Xiao Han had a guess in his heart, and hurriedly ran out of the city.

After getting the tech tree, he was actually a little disappointed.

He thought that there should be a lot of ready-made technology in the technology tree waiting for him to research, and then create powerful weapons.

Unexpectedly, there are only three fruits on the technology tree in the light screen, and although one of them is ripe, the technology bred is also very practical.

But this is just a simple basic technology, and it may be fine to exchange it for some ordinary resources, but if you want to exchange it for level 4, 5, or even human-level resources, it is impossible.

There are still two fruits on the current tech tree, but it is completely unknown when they will ripen and what kind of fruit will be produced.

If these two fruits don't ripen for ten days or half a month, then his plan to use the tech tree to make a fortune may be in vain.

However, seeing these light filaments, Xiao Han suddenly felt that the technology tree in the light screen should be fertilizable.

In this way, the fruit on the branch may ripen quickly, and new fruit can be produced, and the so-called fertilizer should be the corpses connected by the light filament.

This idea is outrageous and completely illogical, but looking at the storage icon at the root of the tech tree, it seems that it is somewhat possible.

"Try it, it's just some corpses anyway!"

Following the light filament extending from his wrist, Xiao Han quickly came to a corpse connected by the light filament.

"Hey, it's a goblin!"

Reaching out and clicking on the storage icon, Xiao Han lifted the goblin zombie and threw it in.

The goblin clan is a master of science and technology, and the light filament is connected to this corpse, which can already show that this zombie should be a scientific and technological person before his death.

It's just that what he's studying can't be seen from the outside.

However, Xiao Han didn't care too much about this, he quickly searched for the corpses connected by the light filament.

In a few moments, the storage space at the base of the tech tree was already full.

Looking at the technology tree at this time, Xiao Han suddenly felt that it seemed to be a little different, but as for what the difference was, he couldn't see it.

"It seems that these corpses are still good for the growth of the technology tree."

Following the light filament on his wrist, Xiao Han quickly searched for the remaining zombies, and in less than an hour, he collected more than two hundred such corpses.

Find Peng Lei and ask him to find some people to move all these corpses to the warehouse.

Whether these corpses are good for the growth of the tech tree or not, it is still uncertain, he just feels this way.

But these corpses must be preserved, because out of more than 10,000 corpses, there are only a few hundred such corpses, and once they are used to breed zombies, it will be difficult to find such corpses.

The population of his village has now increased to more than 400 people, but there are only a dozen people who can attract these light filaments.

This ratio can be said to be quite exaggerated.

If these corpses are really useful to the technology tree, it will also be extremely difficult for him to cultivate the technology tree in the future.

Clicked the white button again, and after the light screen came out, Xiao Han clicked on the icon of the technology tree again, and observed carefully.

Although it had only been a little over an hour, the shape and size of the tech tree had not changed in the slightest, but he still noticed some differences.

"Oh, it's sprouting!"

On the trunk of the Tech Tree, three new shoots are extracted, which means that after a period of time, these three shoots will grow into three new branches

On such branches, new scientific and technological fruits will surely be produced.

When the technology is ripe, you will get new technology, although these technologies may still be basic technology, but for the current cold island, the more basic things are more practical.

If he is given a fighter plane now, or the technological fruit of the kinetic battle armor, with the current scientific research strength of Cold Island, he can only look at it and drool.

Turning off the light screen, Xiao Han was completely relieved at this time, as long as the technology tree could be cultivated artificially, he could collect a large number of corpses of technical talents and use them to ripen the fruit of science and technology.

Don't worry even if all the corpses you just collected are used up, as long as you are strong enough, you can defeat the other islands and loot the corpses needed to cultivate the tech tree.

"Hehe, that's an interesting thing." With a chuckle, Xiao Han never thought that the technology tree would be presented in front of his eyes in this way.

Turning his head to look at the busy Peng Lei and the others, he found that many residents were looking at him with strange eyes, fearful and curious......

"How on earth can you get this head off when you ride a horse?" Turning his head to look at the illusory head on his left shoulder, Xiao Han was a little irritable.

It made him look more like an anomaly, and everyone looked at him in a way that wasn't normal.

"Big ...... My lord! ”

At this moment, Land Rover walked over with more than a dozen bright light stones, Xiao Han looked at it, and hurriedly took a few steps back and said, "You stay away from me, just stand there and say anything about it." ”

Seeing Xiao Han's appearance, Lu Hu's face stiffened, but thinking of the resentful spirit in his body, he had to pull out an ugly smile and said: "My lord, I have a fourth-grade resentful spirit in my body, even if I hold so many bright light stones, I can't completely suppress him." ”

"But when you stand by your side, the spirit in your body will fall silent."

"What, you have a spirit in your body?" Xiao Han was stunned for a moment, and instantly thought of a possibility, and at the same time looked at the back of the Land Rover.

There were also three people standing over there, each holding a large amount of bright light stones in their arms.
