"Yes!"

The two hurriedly got up, then saluted a marked military salute, and then shouted in unison.

"That's good, I'll be relieved!"

Li Mu nodded.

This valley used to be because there was a strange beast with a high cultivation level that occupied the mountain as the king, so other beasts did not dare to haunt here, but there is no guarantee that this strange beast will not be seen for a long time, and other beasts will want to take the opportunity to enter, so with the ability of the two of them, it is good to deal with one or two, if there are more, I am afraid that it will be more auspicious, so Li Mu has opened the * generation.

In the early morning of the second day, when the sky was just dawning, Li Mu jumped into a cave behind the waterfall.

The cave seems to have been formed naturally, because it is located behind the waterfall all year round, and it is about a third of the height of the mountain, so many wild animals have not been found.

Li Mu also found it when he was wandering around here yesterday, and he had already surveyed it at that time, not only did there not have a trace of water vapor in it, but there was never even a trace of a beast entering, so Li Mu temporarily decided to break through at this halfway point of the mountain.

After a simple tidying up, Li Mu sat cross-legged on the laid hay.

In front of him was the bag containing the magic rock.

Now in the cave, Li Mu has set up an enchantment early, ensuring that no trace of spiritual power will leak out from the entrance of the cave.

However, Li Mu still left a rope at the entrance of the cave, in case something happened to the two of them, they could also climb into the cave to ventilate the news.

Crash!

Pieces of dark green magic rocks were poured out by Li Mu, and in an instant, the cave was filled with an extremely rich aura.

Li Mu was overjoyed in his heart, and then he placed a specific cultivation seal on his chest, and then his eyes slowly closed.

As Li Mu's body relaxed, his breathing gradually became stable.

Between his every breath, a trace of spiritual energy was absorbed by him, and then after refining and absorbing through the meridians in his body, it was gradually injected into the cyclone at the dantian.

And those useless exhaust gases were expelled from the body with every exhalation of Li Mu.

In between this exhalation and inhalation, Li Mu completed a perfect energy storage and emission cycle.

Gradually, the cave became silent, and even the sound of Li Mu's breathing had become inaudible, and some were only the sound of flowing water, which was the sound of energy flowing through his meridians.

And the demon rocks in front of him had already floated up, surrounding him, and a trace of white energy seeped out of them, and then drilled into Li Mu's nostrils non-stop.

The energy in Li Mu's body was growing at a speed visible to the naked eye, and even the cyclone in his dantian was gradually becoming condensed.

In this way, the ten days passed in a flash.

Suddenly, at a certain moment, the meridians in Li Mu's body suddenly had an extremely terrifying feeling of swelling pain, and even his dantian also had this terrifying swelling pain.

Li Mu was taken aback at the moment, and then said with joy:

"Master, I'm finally going to hit the foundation building period!"

When the words fell, the seal on Li Mu's chest instantly changed again.

With the change of the seal in Li Mu's hand, the countless energies that filled his body were like floods that had opened the floodgates, and they all rushed towards Li Mu's cyclone quickly.

However, Li Mu unhurriedly mobilized the cyclone, causing it to spin rapidly.

Li Mu was promoted to the foundation building period this time, and he must stabilize every step, he was too eager for quick success in the Tianwu Continent before, so when he was in the foundation building period, he only shrank half of the size of the cyclone's volume, which led to the fact that every time he was promoted in the future, the ability of the cyclone to withstand became worse and worse, so that when he condensed the inner pill later, he almost caused a catastrophe.

In fact, this foundation building period, to put it bluntly, is the foundation laid by the immortal cultivator who entered the first part of the immortal cultivation, the foundation is like building a house, if the foundation is stable, then the house will be built steadily, even if it is a ten-level wind, it cannot shake half a point.

However, the foundation is not solid enough, or it may be just a sneeze, or it may cause the house to collapse.

And now what Li Mu has to do is to compress the volume of the cyclone as much as possible, and then compress the energy that is constantly being absorbed again, and so on, until the energy can no longer be compressed, then the first step can be considered completed.

And this process, Li Mu has lasted for ten days.

Ten days later, one morning, Li Mu felt that he was no longer able to compress it, and the energy that was constantly pouring in had once again filled his meridians.

"Success or failure is here!"

Li Mu sighed lightly in his heart.

Then a soul power was controlled by Li Mu and appeared in his meridians.

To break through the last barrier of the foundation building period, it is necessary to use the power of the soul, because it is like a medium, or more like a catalyst.

Its purpose is to condense the cyclone in the dantian into a substantial cyclone.

Today's cyclones are condensed by a mass of aura, and cyclones that have reached the foundation building stage will become substantial cyclones.

It's like a small whirlpool in water.

Drink!

Li Muqing snorted, and then the soul power went all the way down Li Mu's swollen meridians, and those spiritual powers rushed into the dantian in an instant as if they were attracted by the soul power.

Roar!

A low roar came from Li Mu's throat, and the pain was really unbearable.

At that time, when he was in the Tianwu Continent, the reason why he didn't feel like this was because he didn't have enough energy in his cyclone, so he hastily completed the advancement of the foundation building period.

Now it's different, the energy in Li Mu's body has reached an unprecedented amount, and that amount is still increasing.

Finally, at a certain moment, a roaring sound sounded in Li Mu's body.

Wow!

Then came the sound of the rushing river.

"It's finally done!"

Li Mu let out a sigh of relief, and then the whole thing was already spread on the hay.

Feeling the full power coming from his body, Li Mu's mouth was almost grinning to his ears.

Now he is not only a little stronger than ordinary people, but also more than ten times stronger than his previous self.

Whether it is strength or speed, it has been qualitatively improved.

After resting for about a quarter of an hour, Li Mu got up cross-legged again, controlled a trace of soul power, and cautiously slowly swam towards the dantian.

"How can this be?"

When Li Mu saw his newly formed cyclone, he suddenly shouted in surprise.
