The elixir that can help advance to the Ancestor Realm is extremely rare, and there are only four or five kinds of elixirs that Keke has selected, and there are only three or four plants of each!

These elixirs, if combined with the cultivation of elixirs, will increase their effectiveness a lot. Pen Fun Pavilion www.biquge.info but several people have no alchemy talent, and the effect of Lu Yu refining it into a medicinal liquid is only better than nothing.

About half an hour later, Lu Yu had refined all the medicinal liquids.

Handing it to Keke, Lu Yu lifted the Demon Breaking Spear again, expanding the cave mansion of Xu Fangyuan.

Now the Demon Breaker Spear is much sharper, and the speed of breaking through the stone wall is faster, but after more than half an hour, he has expanded the cave to the size of two zhang square circle.

Together with Keke, after tidying up the cave, the two sat down together.

Keke waved his hand lightly, and thousands of high-grade spirit stones suddenly flew out, surrounding the two of them in the middle.

"Keke is about to start!Brother Lu Yu can release a trace of soul power, feel it carefully!" Keke pursed his lips and smiled at Lu Yu, gently grasping his right hand.

Lu Yu nodded in agreement, and Keke immediately closed his eyes and began to operate the law.

A moment later, the high-grade spirit stones around the two of them began to release a trace of pure spiritual power, and then formed a faint aura vortex around Keke's body!

Lu Yu also released a trace of soul power, and without affecting Keke's cultivation, he carefully sensed the changes in the true element in her body.

This kind of induction probing can only be allowed by people who are extremely close to it!

The cultivation breakthrough itself is extremely difficult, if the person who senses it has evil intentions, as long as he makes trouble at will, not only will the breakthrough fail, but it may also take the life of the cultivator!

With the entry of Lu Yu's soul power, Keke also took the initiative to separate several soul power supports, so that Lu Yu could sense it more clearly!

Keke's True Yuan Vortex was a pure azure color, and at this moment, as the aura entered the body, the rotation speed of the True Yuan Vortex also began to increase.

The pure spiritual power from the top-grade spirit stone was converging at the core of the True Yuan at this moment, gradually forming a small cloud of spiritual energy.

After that, the cloud continued to compress and solidify, and after about two hours, it slowly merged into the core of the true element.

With the integration of the aura cloud, a small piece of water system true yuan at the core of the true yuan began to slowly boil!

Lu Yu understood that this was Keke's "Fire Refining Condensation Pill" exercise with Mo Shuihan, which was assisting in the formation of the Yuan Nucleus.

The formation of the Yuan Core is also the first step to advance to the Ancestor Realm. And this process is generally very slow and arduous!

As the difficulty of condensing became more and more difficult, Keke also began to cultivate wholeheartedly, and he had no time to take care of Lu Yu anymore.

Seeing that Keke's cultivation was progressing steadily, Lu Yu also shrank a trace of his soul power in a corner of the dantian space, and then continued to cultivate and improve the soul cultivation secret technique.

In this way, half a month has passed soon, and with the assistance of the Fire Refining Condensation Pill, Keke's Yuan Core is about to be formed!

Lu Yu put down the cultivation of the Soul Extraction Secret Technique, and carefully sensed the changes in Keke's true element.

About four or five hours later, with a slight "pop", a clear blue crystal nucleus suddenly formed from the whirlpool of Keke's true element!

With the formation of this crystal nucleus, the entire True Element Vortex was slightly shocked, and a large number of True Elements surged and flowed, impacting towards the blue crystal nucleus together!

This process is the most difficult step!

The newly formed crystal nucleus is extremely fragile, and under the impact of its own powerful true element, it is very easy to break and disintegrate! Once the crystal nucleus is broken, it is equivalent to declaring this promotion a failure, and it will take a long time to recover before it can start to impact the Ancestor Realm again!

Keke began to mobilize a large amount of soul power into the dantian space, wrapping the newly formed crystal nucleus heavily to resist the continuous True Yuan recoil!

Lu Yu couldn't help but sweat in his heart, but he couldn't help anything with this kind of promotion!

At the same time, the aura surrounding Keke's body in the outside world also increased again, and even Lu Yu's body was shrouded at the same time.

After two more days, the True Yuan recoil began to calm down, and Keke withdrew some of his soul power, carefully sending the Water True Yuan into the blue crystal nucleus!

This process is the second step in advancing to the Ancestor Realm, strengthening the crystal nucleus.

Only after the crystal nucleus grows to a certain extent, can it truly begin to transform into Yuan Dan!

Seeing that Keke had successfully crossed another threshold, Lu Yu's heart was relieved and he began to practice the Soul Extraction Secret Technique again.

During the cultivation, time flew by, and after more than ten days, the water system true element in Keke's body had all fused into the blue crystal nucleus. At the same time, the crystal nucleus, which was originally the size of a little fingernail, has also become the size of an egg, slowly rotating in the dantian space.

"Hum", a large amount of aura poured in again, and the blue crystal nucleus emitted a faint blue light, enveloping the aura inside, and at the same time, the inside of the crystal nucleus also began to change towards the real Yuan Dan!

At this moment, in the cave outside world, the rich aura has filled the entire cave, and the aura vortex around Keke's body is also spinning faster and faster, inhaling a large amount of aura into his body!

Keke, who was sitting cross-legged on the ground, turned over his hand and took out a jade bottle, poured out a pill and took it, and then continued to impact the Ancestor Realm.

This pill was the Guyuan Pill given by Jin Laoba that day, and Lu Yu transferred one to Keke.

With the elixir entering the body, the aura vortex around Keke's body also became more intense.

There was a dense sound of "pop pop ......", and more than 100 high-grade spirit stones that were relatively close to them all suddenly shattered, obviously having exhausted their spiritual energy.

With a wave of Lu Yu's left hand, thousands of high-grade spirit stones flew out and piled up around the two of them.

After the aura vortex rotated to a certain speed, it gradually stabilized, Keke's impact process stabilized again, and the blue crystal nucleus in the middle of the dantian space began to slowly transform towards the Ancestor Yuan Dan.

Lu Yu put his mind at ease again and re-cultivated the Soul Extraction Secret Technique.

After another month, the aura vortex around Keke's body rolled violently again, frantically pouring into his body!

"It's done!" Lu Yu was overjoyed!

In the induction, within Keke's dantian space, a Yuan Dan the size of an egg with a blue color has been fully formed!

The violent spiritual power swarmed into the dantian space, and Keke did not stop cultivating, but used this sufficient spiritual energy to begin to stabilize the realm of the first order of the ancestor realm.

Lu Yu withdrew his soul power and thought in his heart.

Keke's promotion to the ancestor realm this time can be said to be smooth sailing, and he didn't encounter any trouble!

On the one hand, this comes from the powerful talent of the Heavenly Demon Holy Body, and on the other hand, it is also because the Heavenly Demon Divine Maiden has been inherited for a long time, and the cultivation method is extremely suitable for herself!

But Lu Yu is the Five Elements Holy Body, this physique has always been difficult to break the mirror, although this time he was able to personally sense Keke's promotion, which helped him a lot, but when it really came to breaking the mirror, he was afraid that he still had to face a lot of difficulties!
