During the retreat, the first thing Tang Mu did was not to improve his strength, but to clean up what he had gained and gained when he went out this time.

The first is the meta-core, which is the most basic thing, and it is also a hard currency that is harder than gold before the end of the world, and even directly replaces the currency before the end of the world, and the yuan crystal is called the two major currencies after the end of the world.

This time, from Tang Mu's departure to his return, a guardian Yuan Crystal is not a few, there are hundreds of thousands, the reason why there are so many is because he got the remnants of the treasure of Xuanhuang Cave Heaven, there are so many, otherwise it would be good to be able to have hundreds of Yuan Cores.

Yuan core, for Tang Mu, is not the most, the most is the Yuan Jing, these Yuan Crystals are always brought by the monks who have always entered the Xuanhuang Cave Heaven Adventure, these monks died, and the Yuan Crystals on their bodies were left in the Xuanhuang Cave Heaven, and finally cheapened Tang Mu, so that Tang Mu got millions of Yuan Crystals, although these Yuan Crystals are of different grades, but for Tang Mu, it is a huge wealth, and it is the foundation to support his early development in the last days.

The protection of the Yuan Core and the Yuan Crystal, compared to Chu Feiling and the others who brought many survivors, and the Yuan Core obtained by using the Evolver to fight is not counted as hunting, which shows the number of Yuan Cores and Yuan Crystals harvested by Tang Mu.

Then there are all kinds of exercise cheats, these exercises are the local creatures in the Xuanhuang Secret Realm who enter the treasure of the Xuanhuang Cave Heaven to go on adventures, and they are left behind after death, and all kinds of cheats have been accumulated.

These secret realms are the same as the Xuanhuang secret realm, divided into five categories, technology, runes, cultivation, martial arts, and abilities Five cultivation methods, these five cultivation methods, there is no distinction between high and low, they are all cultivation secret realms that can make human beings evolve, but the different types of cultivation and the focus of evolution are different.

In the cultivation of science and technology, it is the brain that evolves, that is, the spiritual power, and finally it will become very smart, which is conducive to scientific and technological research, and can even produce some abilities that are conducive to scientific and technological research, and the use of these abilities can even produce and create black technology.

Rune cultivation is also the cultivation of spiritual power, but its cultivation of natal runes makes the rune monks have an extremely strong affinity for rune system technology, and their ability to make runes has greatly increased.

Martial arts and cultivation, one is a dual evolutionary of physical body and qi, and the other is a dual evolutionary of qi and god, and the ability is focused on special abilities, and the direction of evolution is also different.

These cheats are absolutely very important for the development of Tang Mu's forces.

"There are so many cheats, when the territory is really built, you can build a library, put these cheats in it, and train your subordinates."

For cheats and knowledge things, as a modern human being, naturally know its importance, knowledge is power, although this sentence is not absolute, but knowledge can make people master power, or gain power, there is absolutely nothing wrong.

Yuan core, Yuan crystal, and cheats are the three most basic types of harvests, and then there are some other harvests, which must be said to be mutant beast meat, important parts of the mutant beast or mutated parts, this kind of natural treasure is not a few.

After that, there are treasures, these treasures Tang Mu harvested is not small, divided into three kinds of harvests, one is to hunt mutant beasts, harvested from mutant beasts, and the other is to hunt mutant beasts, obtained from the place guarded by mutant beasts.

The treasures obtained in these two cases are not very many, but the quality is good.

The third category is those natives of the Xuanhuang Secret Realm who ventured in the Xuanhuang Cave Heaven and died and left behind.

The so-called treasure is actually a treasure that produces evolution, a very precious treasure, such a treasure is what every evolutionary dreams of, and this treasure even has infinite evolutionary possibilities.

In addition to this kind of treasure that can evolve infinitely, there are also some ordinary treasures, there are many ordinary treasures of this kind, all of which are treasures of a fixed level, although they cannot be compared with treasures, but they are definitely high-quality treasures.

Whether it is a treasure or an ordinary treasure, it can be roughly divided into two categories.

The first type is formed after the mutation and evolution of things that already existed before the end of the world, and the second type is born out of nothing under the dual action of the blessing of the Heavenly Dao and the chaotic vitality.

In the end, it is the treasure of Xuanhuang Dongtian, this is all the harvest that Tang Mu has gained this time, with these gains, the initial capital development of the territory that Tang Mu is about to establish does not need to worry.

After cleaning up the treasures, Tang Mu divided these treasures into categories, except for those treasure-level treasures that could evolve infinitely and powerful magic weapons such as Xuanhuang Dongtian, Tang Mu asked people to clean up the other things and let Chu Feiling send people to collect them.

As the things in his hands were sorted out and cleaned up, Tang Mu began to prepare to improve his cultivation, and the Nine Lives and Nine Deaths Heavenly Gong was constantly operated by Tang Mu, and Tang Mu began to absorb the Yuan Core to improve his strength.

This is also the first time that Tang Mu has used the power in the Yuan Core to improve the level of evolution, but fortunately, this is to use the energy in the Yuan Core to cultivate, rather than directly devouring the power in the Yuan Core.

After all, Tang Mu knew that this kind of thing contained the will left by the original owner of the Yuan Core after his death, and if it was directly devoured, it would definitely not be a good thing for the evolutionary, and it would not be a good thing, and it would not even be taken away by the original owner of the Yuan Core.

In the memory of the reborn Tang Mu, in his world, there were many people who directly devoured the Yuan Core, and finally caused many survivors to be taken away by this mutant beast, which became powerful and began to besiege the survivor base, causing the world to be very chaotic.

Tang Mu estimated that this was also the reborn Tang Mu's world, and there was still no change in the three thousand years after the end of the world, and the survivors could only struggle to survive in the last days was the same.

Tang Mu naturally did not directly devour the Yuan Core, but used the Nine Lives and Nine Deaths Heavenly Skill to refine the Yuan Core Cultivation, and in this process, Tang Mu's cultivation began to become stronger and stronger

With Tang Mu's continuous operation and skill cultivation, Tang Mu's cultivation is constantly improving......

The beginning of the first order and the seventh level of the first order, the middle stage of the first order and the seventh level......

The early stage of the first order and the eighth level of the first order, and the middle stage of the first order and eighth level......

Soon, Tang Mu's cultivation was raised to the level of the ninth level of the first order, and this kind of cultivation was definitely unique in C City.

Soon, Tang Mu's cultivation was promoted to the level of first-order tenth-level perfection, and at this time, Tang Mu's cultivation seemed to encounter obstacles.

"Break it for me!"

Feeling the bottleneck of the first order consummation to the second order, Tang Mu was immediately very unhappy, and he decided to directly impact the second order, which was also his opportunity.

"Bang ......"

With Tang Mu's efforts, in a soft sound, something in Tang Mu's body seemed to have broken, which suddenly made Tang Mu look extraordinary.

This is the result of Tang Mu's efforts, and with the breakthrough of this bottleneck, Tang Mu's physical body began to accept the baptism of the power of heaven and earth.
