The aura convergence fluctuations caused by Zhen Han naturally made the fourth senior brother sense, the fourth senior brother had already tested Tang Tie's root bones, and now the fourth senior brother was stabilizing his realm, but once again feeling the aura fluctuation caused by the little junior brother, the fourth senior brother had no choice but to stop and hurriedly go over.

When the fourth senior brother saw that Zhen Han was really asleep, he suddenly felt a little speechless, and at the same time a little envious, the little junior brother can cultivate when he sleeps, but absorbing aura is not a simple matter.

Fortunately, there are not a lot of aura around, and it has been absorbed by Zhen Han once, and there are not many aura gathered this time, and the fourth senior brother is sitting here to check for Zhen Han.

And the three little guys in Zhen Han's body continuously sent the absorbed aura to the middle dantian, and the aura was absorbed by the internal force seed and converted into a large amount of red mist, these are all internal forces, these red mist did not produce the same internal force as these three little guys again, these red mist constantly rotated around the internal force seeds.

After a long time, the aura around Zhen Han was almost absorbed, and the three little guys stopped after finding that there was no aura, and when they returned to Zhongdantian, the three little guys found that their homes were still like that and there was no change, only that there was a lot of red mist around.

The three guys were a little overwhelmed when they saw this, and they were a little sad to see their home become like this, but for some reason, perhaps out of instinct, the three guys guided these red mist to turn around in the meridians.

The aura fluctuations caused by these three guys also made Zhen Han's body feel very good, although most of the aura was sent back to the middle dantian by the three little guys, but a small part was still absorbed by Zhen Han's body, Zhen Han's body was in a lot of deficit due to the influence of the spiritual power around his consciousness last time, although there was a pill supplement made by the fourth senior brother, and the meal he ate this morning, but the body deficit was not replenished so quickly.

The absorbed aura is different, the aura is a special energy, Zhen Han's body recovered a lot faster after absorbing these aura, only to see that Zhen Han's original pale complexion became more ruddy.

Moreover, the three guys guided the internal force seeds of the middle dantian to absorb the internal force of the spiritual energy transformation and constantly rotate the meridians, and there was also a part of the energy that continued to replenish the body, and Zhen Han's body recovered at a very fast speed.

It is a slow process for cultivators to absorb aura through breathing and convert it into internal force, it is very difficult to decompose aura, like the fourth senior brother, the fourth senior brother has reached the realm of practicing the spirit and returning to the void, and has reached a certain connection with the seven spirits, the amount of aura that the fourth senior brother can resolve every day is not very much, if it is to be converted into units, it is like a spirit stone, it has a thousand units of aura, and the fourth senior brother can digest and absorb less than one unit of aura a day.

And Zhen Han absorbed at least three or four units of aura just now, and today he absorbed at least five units of aura for the first time, of course, the quality of aura is also different, the quality of aura is divided into twelve levels, divided into four levels, that is, lower, middle, upper, and best four spirit stones.

It is difficult for the earth's current environment to produce spirit stones, as for the best spirit stones, it is impossible for the earth to exist now, of course, the earth will naturally have such an environment in the future, or the solar system will have such an environment.

And the quality of the aura absorbed by Zhen Han is very low, and it is impossible for a low one to form a low-grade spirit stone, so the earth does belong to the era of the end of the law now, and the amount of aura and the quality of the aura are too poor.

Of course, as long as there are many species of life on the earth, the aura will naturally be produced, but this also depends on the ecological balance factor, if the ecology is more seriously unbalanced, then the quantity and quality of natural aura will be worse.

The aura absorbed by the fourth senior brother is converted into a new internal force through the internal force seeds in the dantian, and these new internal forces are different from their own internal forces, and they contain very little of their own breath, so they must continue to carry out meridian turnover, and constantly transform them through meridian turnover, when the meridian turnover reaches a certain level, and then through the internal force seeds and the internal force in the body continue to fuse, so that this new internal force completely becomes the quality of the fourth senior brother's current internal force.

This process is very complicated, the fourth senior brother can only digest less than one unit of aura in twenty-four hours a day, and it is a relatively poor quality aura, you can imagine how difficult it is to absorb and digest aura.

Of course, the role of aura is not to strengthen the internal force, but there are more functions, most of the aura absorbed by the fourth senior brother is used to strengthen the internal force, and a small part is absorbed by the body.

The reason why Zhen Han was able to absorb so much aura was not how powerful Zhen Han was, but that the three guys in Zhen Han's body were powerful, and it was the first time they absorbed more than five units of aura, and these auras completely made these three little guys convert from an energy state to a gaseous state, and the internal force seeds in Zhen Han's body were in a liquid state.

As for the conversion of the spiritual energy absorbed for the second time into internal force, under the guidance of these three little guys, it is not running in the meridians at a rapid pace, and it is three motors running at the same time, can it not be fast?

However, due to Zhen Han's physical condition, it took several hours for the three little guys to transform these internal forces, and the fourth senior brother came to see Zhen Han several times in the past few hours, and found that Zhen Han didn't have any moths and left.

What are the four senior brothers busy with? Of course, it is a police drone, and it is very good for the fourth senior brother to see during the day, even if it is a few hundred meters or a thousand meters, the fourth senior brother can see it, you must know that the internal strength of the fourth senior brother has a certain connection with the existence of the seven spirits.

In a secret room of the police station, several people were observing the situation of the fourth senior brother through a drone, which was originally viewed more than a thousand meters away, but due to the operator's carelessness, some movements were caused by the fourth senior brother.

The fourth senior brother was very curious about this thing, Tang Tie naturally told the senior brothers about the situation of the drone, so the fourth senior brother didn't want people to explore his own situation, so he would naturally think of a way to take it down.

In the past few hours, the fourth senior brother has chased the drone and ran for dozens of kilometers, and the drone has been hit by the fourth senior brother's stone several times, but fortunately, the distance is too far, and the strength of the stone is much weaker, so it was not smashed down.

When the stone hit the drone, several leaders in the secret room of the police were shocked, originally these leaders wanted to see how powerful the fourth senior brother was, and indeed the light skills of the fourth senior brother shocked them, but after seeing more, they also got used to it, but this is almost a thousand meters away, and it is still moving, and the fourth senior brother can hit such a small individual as the drone is too terrifying.

Although this military drone is not very small, it is only half a meter wide, but you must know that the distance is a thousand meters, even if a person is a thousand meters away, it is a lot smaller, even if it is a sniper master, it is difficult to hit an irregularly moving drone, and the fourth senior brother actually uses stones.

In the end, the fate of the drone was naturally destroyed, in fact, it was not fought down by the fourth senior brother, although the fourth senior brother occasionally hit the drone, but the distance was too far and the strength of the stone was not enough, and the drone was chased by the fourth senior brother and crashed without power.

After the drone crashed, a person in the room said: "Withdraw the personnel, don't worry about the drone, this matter is classified as confidential, Xiao Liu, wait for you to give me a copy of the video." ”

After chasing for a few hours, the fourth senior brother came back with a drone, Tang Tie also looked at the drone, and felt that it was too good, the drones he used to play with were scum.

At this time, Zhen Han also woke up.
