The project of the dungeon renovation went smoothly. It was the first time that Tang Lin evolved into the spirit of Xu Earth to transform the terrain on a large scale. The so-called practice makes perfect is indeed true. Tang Lin also had a sudden idea during the transformation process, no longer standing on the ground to transform the dungeon several kilometers, but directly merged with the entire land.

This way, the transformation speed is faster and the control is more accurate. Almost after obtaining the design drawings, Tang Lin can complete the reconstruction with just one idea.

The first dungeon renovation took two days to inspect and the second one spent a day in order to be cautious. Later, everyone simply saved the inspection process. After Tang Lin renovated one, he went directly to the second one.

But even so, Tang Lin spent nearly three months to complete the transformation of more than 10,000 planetary engines. The effect was better than expected. The original calculation was to accommodate up to one billion people, but after new statistics, the number became 1.2 billion.

Therefore, there are still 2 billion humans left on the surface of the earth.

Originally, there were still 2.3 billion, but that 300 million had died quickly in the past few months. Some people committed suicide, some were murdered, some died by accident, some were unattended at home for various reasons, and some were turned into thugs and shot by the coalition government before the end of the world...

When Tang Lin saw this number, he was silent for a long time.

I thought that as a giant in the high-dimensional world, he had all kinds of magical abilities and was a god in this world of demon-free technology. However, he had tried his best, and these 300 million people died so quietly in places he could not see. Tang Lin didn't even know that these happened before seeing this number of casualties.

Human beings are really too fragile, and saving human beings is too difficult.

"Is there two billion left?"

Tang Lin stood on Mount Everest, the world's highest peak, overlooking the earth. There was snow in front of him, and the white world was still spreading outward. The surface of the earth has begun to cool down significantly, and the work of human relocation is also rapidly unfolding.

A green light appeared on Tang Lin's shoulder, and Hela walked out of the teleportation light gate and stood on Tang Lin's shoulder.

"The research, have there been any results?" Tang Lin asked.

"It's true. Your friend in another world has proposed an idea. You can use the water spirit beads to cultivate a group of special insects. Using this insect to parasitize humans can allow humans to gain a certain degree of cold resistance within a few days and survive in low-temperature environments."

Tang Lin had no choice but to seek help from creatures from other worlds. The Water Spirit Pearl comes from the World of Fairy Sword, so Tang Lin immediately wanted to ask experts in those fields.

Lin Qing'er made a suggestion that the human body cannot bear a large amount of water spirit bead spiritual power in a short period of time, so perhaps it is possible to inject spiritual power into the human body in a more gentle way.

Lin Qing'er is a witch queen. She can be said to be the one who knows the best of Gu insects. She quickly used the spiritual power of the Water Spirit Bead to cultivate a mutated puppet insect. The puppet insect can control the corpse, but in fact it uses the venom it secretes to manipulate the nervous system of the corpse. This method can be used to slowly inject the power of the Water Spirit Bead into the human body, so that humans can have a certain degree of cold resistance.

Perhaps you cannot directly resist the extreme environment of minus 70 degrees Celsius, but wearing thicker clothes should be able to resist the extremely cold environment.

"What about the quantity and side effects?" Tang Lin asked.

"It is not difficult to cultivate insects. The method of refining the Gu is very interesting. One bottle can hold tens of thousands of small insects, but there are too few people who can raise these insects. In a short period of time, the number of insects that can be provided cannot exceed 100 million. Moreover, there is a certain mortality rate, about three-thousandths." Hela continued.

A mortality rate of 30,000 yuan. If it is a vaccine, this number can scare social unrest in normal times, but it should be acceptable in this chaotic world. However, the number is still too small. The world of fairy sword belongs to the ancient world of fairy tales, and there is no industrial system at all. Cultivating these mutated puppet insects is artificially bred in Miaojiang. This number is probably used to use all the people who can refine the Gu.

"The quantity is still not enough." Tang Lin sighed.

"I don't understand what you are annoying?" Hela asked with her hands in her arms a little strange.

Tang Lin raised his hand, pointed to the vast land, and said to Hela: "There are 2 billion people. I want to save them, but I didn't think of a way."

There seem to be many ways. The mutated puppet worm can transform 100 million humans, and Tang Lin’s storage space can accommodate 20 to 30 million humans. Tang Lin spent some time to build a safe zone and resettle a population of 100 million may be barely able to do it.

However, for the 2 billion people, the difference is still too far.

There is no way to completely solve the problem. I can only hit this number with hammer and stick. The knock-down part is less than one-fifth.

Time waits for no one, and this is what Tang Lin lacks the most now.

Every moment Tang Lin delayed, these humans would die in thousands of times, which made Tang Lin very irritable.

"But what does they have to do with you? You have saved many people, why do you have to save them all?" Hela said in confusion.

This is a bit reasonable. Originally, Tang Lin shouldn't have so much empathy towards these tiny humans. He should have the mentality of saving as much as he can, and he doesn't care if he does his best.

But after a few months of busyness, Tang Lin became increasingly interested in saving everyone.

Perhaps it is not a great idea, but just a simple idea of ​​playing games and trying to achieve full marks and get all the achievements and props.

"If people on this planet can't survive, why not send them to other places?" Hela asked again.

"Send to other places? Do you mean... other worlds?" Tang Lin asked back in surprise.

"Yes, why can't it?"

"But, isn't the efficiency of space transmission very low? Your biosphere experiment has not collected enough 100,000 creatures."

Tang Lin hadn't thought that this would allow these people to survive by sending the people who wandered on Earth to other worlds, but it was still a matter of time. How could it be too late to transmit more than one billion people?

"Are you getting something wrong? I rely on the breath you left in other worlds to locate it, so it's difficult to catch wild animals. However, you can organize these people and as long as you can get together, you can conduct group teleportation."

Tang Lin was shocked. He actually had such an operation.

If this is the case, it would not be a wandering earth, but a race migration.
