Gubo felt that he had discovered an incredible secret, most likely involving the origin of human beings on Earth, and he had been in the air, observing the apes below.

This group of apes, although still living in groups like primates, has already become tribal and gradually formed the rudiments of society.

It may take a long time, but after all, it is in the process of evolution, and Gu Bo believes that these apes will move towards the civilization that humans have experienced today.

Given that these apes all have super awesome abilities, they may move towards a cultivation civilization rather than a technological civilization.

Judging from the evolutionary speed of this group of apes, by the time they formed a human society, the current human civilization would either go to the universe or have already gone to extinction.

No matter how you look at it, this group of people is like the successor of the human race on the earth, becoming a new human race on the earth.

The light in the space gradually darkened, and it turned out to be night, and there was originally a day and night here, and Gu Bo felt the wind blowing.

Even, not long after in the dark, I saw a burst of lightning and thunder in the distance, the air became moist, and raindrops fell.

This is a complete ecosystem, Gu Bo was shocked, was it a legacy of antiquity, or was it built by aliens?

Gu Bo left the colony of the giant ape, explored the space, and found a place in the space with a height of 100 meters.

There was nothing in it, just a blank altar, and the material from which it was built was stone, or to be precise, jade.

Gu Bo wanted to find some information in it, but there was nothing in the entire altar, not even a single recorded symbol.

This mysterious underground space is not small, half the size of a Chinese country, 666 meters high, which is the height accurately measured by Gu Bo.

There are mountains, water, rivers, and even a place that belongs to the sea.

Everything has a complete circular ecosystem, there are fish in the water, and many fish can be seen on the surface of the earth.

Of course, there are also some that do not exist on the surface of the earth, or are extinct.

Gubo saw saber-toothed tigers, mammoths, these animals that have become extinct on the earth, and even some animals that have not been found on the earth so far.

Who built this underground space?

Gu Bo didn't find the answer, but he was interested in exploring the universe, and he decided that he must get an advanced equipment that can explore the universe back.

Coming to the gate of the passage leading to Kunlun, Gu Bo began to study, how to open the door without damaging the giant gate?

To be precise, it is to control this gate, since such a mysterious space has been discovered, it can be used as the location of the cultivation world, and there are no two strongholds in the cultivation world.

"Master, you don't have to control this door, you can arrange a space portal in the passage. The praying mantis said suddenly.

"Arrange the space portal?" Gu Bo's eyes lit up, and he felt so tall.

"Will you decorate?" looked at the praying mantis suspiciously.

"Yes, yes, after all, the earth's space is too weak for me, and it is too difficult, that is, the problem of materials. The praying mantis nodded.

"That's it, you make a list of the materials you need for me, and you can also find out where there are materials, just arrange a portal here, and the base of the cultivation world will be set here. Gu Bo waved his hand and made a decision immediately.

Gu Bo did not leave here, but lived in this mysterious space, and he wanted to explore whether the origin of this mysterious space and the ecological system of this mysterious space were exactly the same as the surface of the earth.

In addition, Gu Bo is also looking for elixir here, although the level is lower, it can also be used to practice hands, be proficient in alchemy, and increase the rate of becoming a pill.

The flora and fauna of this mysterious space are still very rich, and some of the things that exist on the earth, or those that do not exist, or even those that have become extinct, can be found here.

Ginseng naturally exists, and I don't know how many years it has grown, Gu Bo dug out one, a ginseng with the thickness of a baby's arm, with a strong medicinal fragrance, has been out of the ordinary ginseng category and has become an elixir-level ginseng.

Or it can be called spiritual ginseng.

The praying mantis had already left, and after exploring this underground space, it lost interest, and it couldn't even find an opponent, so how could it be interested.

Gu Bo stayed here with Fa Yi, as for the apes living in this space, although they have some abilities and their strength is okay, but in front of Gu Bo, they are still far behind.

In terms of strength, even Wu Yi and others can't beat it, it's just that there are enough numbers.

Gu Bo stayed here, looking for elixirs, and even catching spirit beasts to eat, which naturally attracted the attention of these apes, but after Gu Bo showed his high strength, one by one the apes knelt down.

Perhaps, in their hearts, Gubo is an omnipotent god.

If, one day, these apes evolve into humans, maybe there will be myths and legends about Gubo.

Gu Bo's heart is full of bad taste, maybe how many years later, the human race will be spreading the legend of the great god Bobo opening the world......

After collecting some of the medicinal materials, Gu Bo took out the Biyan Mu Dan Furnace and began to refine the pill, although the pill was of low grade and of little use to him, it could be rewarded to Wu Yi and the others.

Moreover, Gu Bo also had the idea of selecting some people and teaching them the method of cultivation to enrich the cultivation world.

This time the alchemy is mainly to master alchemy and improve the efficiency of Cheng Dan, the first furnace of pills, half of which was wasted, but it is also a good start.

You must know that most alchemists, when they are able to become a genius when they are able to do alchemy for the first time, most of them end in failure.

Gu Bo's first alchemy can become fifty percent of the pill, and if it is in the cultivation realm, it is definitely a demonic existence.

This is the power of systematic indoctrination learning.

In the following furnaces, the rate of Cheng Dan continued to increase, and among the last furnace of pills, there was no waste pill, and Gu Bo was satisfied.

This time for alchemy, it took three days to refine several pills, Gu Bo felt that his alchemy was already perfect, even if he refined high-grade pills, the success rate should not be low.

Only then did he select an elixir from the storage ring and the elixir traded from Tianming, and began to officially refine the high-grade elixir, which was a tempering flesh-like elixir that had a great effect on his realm.

As for Xiao Xuandan, the grade is too high, Gu Bo is not in a hurry to refine it for the time being, after all, there are only ten medicinal materials in total, and if he refines and discards one, he will have one less, which is related, the key pill he stepped into the realm of Sanhua Ning Dan.
