Originally, some people were only suspicious of Xiao Chen, but Mu Mu's sudden visit brought this issue to the table.

Everyone waited to see his attitude, but whether Xiao Chen saw it or not, he would be criticized.

As long as the two met, those people would think it was evidence of his collusion with Mu Mu.

Even if he never sees him back, or leaves Mu Mu, others will think that this is a show, Mu Mu just cooperates with the formalities, and is suspected of wanting to cover up.

Anyway, no matter what he does, as long as others have doubts about him in their hearts, he can't get out of it.

At this moment, the housekeeper reported that Mu Mu had arrived at the living room.

"Make her wait!"

Xiao Chen doesn't have a good temper, don't you want to see me?

Then just wait!

Although this is very ungraceful, this is the only way Xiao Chen can think of, and it is also the method with the least impact.

People who doubt him still don't think that he is innocent like this, but if he humiliates Mu Mu like this, it will also make some people willing to believe him.

Then, Xiao Chen swallowed a few times, calmed his mood, and began a new cultivation.

Not far from him, Professor Cang also began to cultivate.

Under the investigation of Mu's Eye of Truth, it was quickly seen that Xiao Chen's old grandfather spirit now had an energy of 143 points, that is, the first order of silver.

It stands to reason that Xiao Chen's old grandfather's spirit is more active than him later, but he didn't expect to run in front of him.

His cultivation method is somewhat unique, instead of using sponge meditation methods to slowly absorb free cosmic energy, he also swallowed a strange bottle of medicine.

"Huh? I see......"

Mu used the Eye of Truth to analyze it, and found that the active ingredient of that potion was very similar to the pure cosmic energy he had compressed with the Black Hole Meditation, and if he absorbed this energy to cultivate, it should be much faster than regular cultivation.

This old grandfather's divine soul has a lot of secrets on his body, first those high-quality life elixirs, then the mid-level breakthrough elixirs that are not expensive but of excellent quality, and there are even elixirs that can be used for the cultivation of the divine soul......

There are some things in this world that can speed up the cultivation of divine souls, but it is very difficult to obtain, the stock is very small, and the price is extremely high, even if it is a net worth like Mu Mu, it is impossible to continue to supply it.

He thought that he had made this potion by himself, but he didn't know how it was made.

Obviously, the other party has a lot of secrets that do not belong to this era!

"Could it be that he is a lost civilization?" Mu thought of this possibility.

If his guess is true, then this old man is really terrifying.

His curiosity is also very strong, and when he knew about the existence of the lost civilization, he spent a lot of time to understand it, and even had a certain understanding of the composition of this world.

There are seven federations in the universe that balance each other, and outside the control of the federation, there are a large number of small and medium-sized forces, as well as several superpowers that transcend everything.

Although human beings have completely entered the interstellar age, such as interstellar gates and space jumps, they also have them, but there are a large part of them, and human beings can only use or copy them, and they don't understand the principle at all.

All of these things have been excavated from the relics of lost civilizations, and most of the development of human civilization is also the research results obtained from lost civilizations, and there are many things that have not yet been thoroughly understood.

It can be said that the Lost Civilization is an era that is far more powerful than the present, they should have unprecedentedly powerful technology, as well as all kinds of powerful super potions, etc., everything about modern human beings can only be regarded as picking up people's teeth and wisdom at most.

I don't know why such a powerful civilization was so cleanly shattered, leaving only some ruins and wreckage in various parts of the universe.

After the collapse of that era, I don't know how many years have passed since today, and a soul can be preserved like this, it is definitely not ordinary, I am afraid that it is the top existence of that era.

Such people, in this day and age, are simply a mobile treasure trove!

After the old man's spirit swallowed the elixir, the energy of those potions was not absorbed at once, but was stored in the body, absorbing little by little, which was similar to Mu's cultivation method.

However, relatively speaking, the energy obtained by Mu using the black hole meditation is purer, and the cultivation efficiency is also higher.

The old man's spirit was not idle after swallowing the potion, and he was refining the elixir on the side, and Mu could see that it was not the intermediate breakthrough elixir from last time, but other elixirs.

Since it may be something that has lost civilization, it should have enough value, and this time it is not a mass-produced product from the last mass production, and it should be a high-quality product.

Because the distance was close enough, Mu controlled his clone to enter it, one to record the process of refining the old man's potion and those materials, and the other to carefully observe Xiao Chen's cultivation.

Xiao Chen is still cultivating the absorption potion, but there is nothing surprising, when he absorbs enough potion, when he uses the refining method, he should be able to see the difference.

The elixir that the old grandfather soul refined this time also took a surprisingly long time, he fiddled in front of a large number of instruments, and he could also generate strange flames to refine the potion......

If you want to become a pharmacist, you also need corresponding talents, and to refine a real potion, you need to have a special spirit to do it.

In other words, to be able to successfully refine a potion, or a good quality potion, all require the means of the divine soul.

Without such talent, at most you can only become an assistant or researcher of a pharmacist.

I don't know how long it has been, Xiao Chen's side has come to an end for the time being.

Under Mu's Eyes of Truth, it was obvious that his body had accumulated a lot of impurities, and his absorption system had entered a state of fatigue, and if he continued to take the potion, the absorption effect would be very touching.

At this time, after resting for a day, the body can recover naturally, and using the refining method can speed up the recovery.

Xiao Chen got up and moved his body, then looked at the time, and asked the housekeeper again, and learned that Mu Mu was still waiting in the living room, not anxious or anxious, and seemed to have a posture of not waiting for him to swear not to give up.

"Since you want to wait, let's keep waiting!"

After Xiao Chen sneered, he sat down cross-legged.

He really didn't disappoint Mu, and finally began to refine his body!

I saw that he took out another potion, uncorked the bottle, and swallowed it in one gulp.

"What are you doing, isn't it very bad to continue cultivating like this?"

In the state of exhaustion of the absorption system, the absorption agent is completely wasted, and ten percent of the absorption is less than one percent, which is costly and laborious, and the gains outweigh the losses.

He also quickly understood Xiao Chen's intention in doing this, it turned out that that the elixir was not a life elixir for ordinary cultivation, but an auxiliary elixir for some special refining method!

Mu, who used the Eye of Truth to observe, could see the movement of the energy in his body, and the potions that entered Xiao Chen's body automatically decomposed into two parts, one of which seemed to be useless and did not play any role.

And the other, after being separated from the potion, became lively, and then they spread throughout Xiao Chen's body, soaking into every inch of his body.

At the same time, Mu obviously saw that the impurities accumulated in Xiao Chen's body were being purified, and the absorption system was also recovering little by little.

His speed is several times faster than when Mu Mu watched Mu Mu refining before!

It seems that this is the special refining method he is looking for this time!
