After Lin Xue's matter passed, Li Chen began to practice in the Heavenly Demon Valley.

This Heavenly Demon Valley is a yin land that the world avoids, but for Li Chen, who has the five-turn nirvana technique, it is no different from the spiritual land.

However, although he could easily cultivate alone, he did not forget Yu Yu and Lu Nan.

Since these two people are now his disciples, Li Chen also plans to let the two of them cultivate together.

However, the Five-Turn Nirvana Secret naturally could not be passed on to them, so Li Chen planned to build a large magic circle, a magic circle that was enough to transform Yin Qi into Spiritual Qi.

Li Chen didn't bother to think of a name, so he directly named this magic array the Heavenly Demon Great Array.

The Heavenly Demon Great Array was composed of two formations, the Yin Gathering and the Soul Transformation Array, and the scale was a little smaller than the Spirit Sword Great Array, even so, it was more than enough to provide the three of them to practice.

And when he heard that Li Chen was going to build a magic circle covering the entire Heavenly Demon Valley with his own hands, Lu Nan was first shocked and speechless, and then ecstatic.

What does such a magic circle mean, it means that he can cultivate in the same place as those legendary cultivation holy places from now on, and this benefit is enough to replace the Yin and Yang Dual-Yuan Pill.

Therefore, without Li Chen's instructions, after Lu Nan asked about the materials needed to build the formation, he directly ordered the people of the Heavenly Demon Sect to gather those precious materials as quickly as possible.

Taking advantage of the busy time of the Heavenly Demon Sect's people, Li Chen took out the "Blood Rain Poisonous Wood" and refined it into a Condensing Pill for later use.

Then it took him another day to build this Heavenly Demon Great Array.

From then on, the rich yin qi in the Heavenly Demon Valley began to be continuously gathered by the Yin Gathering Array, and then turned into a steady stream of spiritual energy through the Spirit Array.

Like the Spirit Sword Great Array, the transformed aura in the array was also so dense that it was almost atomized.

Li Chen and the three of them practiced inside, and their cultivation was almost a thousand miles a day.

And Li Chen's cultivation speed far exceeded that of Yu Yu and the others, and most of the aura in the formation was absorbed by Li Chen.

On this day, Li Chen, who was in the array, suddenly let out a long breath of turbidity, and then his eyes opened, and the essence appeared.

"After so many days of cultivation, you can try to start condensing your divine thoughts. The Immortal Venerable in his mind reminded lightly.

Li Chen nodded slightly, and then directly took out the Divine Concentration Pill and took it.

When the pill entered his abdomen, Li Chen immediately pinched his hands into a mysterious trick, and the aura in his body was mobilized by him according to a special route.

This kind of mobilization of spiritual energy did not make his breath change in the slightest, because he was running the immortal family method "Acquired Divine Formula".

"Acquired Divine Formula" is a powerful method of condensing divine thoughts, and after operating it, it will only have a spiritual impact on the immortal cultivators, and will not affect the cultivation, and its lowest cultivation threshold is the middle stage of foundation building.

As the medicinal effect of the pill in the abdomen began to emanate, those mysterious meridians began to absorb all the medicinal effects that were emitted, and at the same time transmitted this medicinal effect to Li Chen's skull, and began to forge Li Chen's sea of consciousness.

Li Chen only felt that his brain was extremely energetic at the moment, a taste that he had never experienced in his life, so he couldn't help but feel secretly gratified.

"Don't be fooled by this small achievement, you're far from condensing. ”

"You are only mentally increasing now, but your spiritual power is far from divine thoughts, you must keep your mind tightly and continue to temper!"

Immortal Venerable reminded in Li Chen's mind.

He himself has always been parasitic on Li Chen's mind, so he is the most intuitive about the changes in Li Chen's mental power, even clearer than Li Chen himself.

Li Chen nodded silently, biting the tip of his tongue slightly, using the stinging pain of the tip of his tongue to forcibly stabilize his mind, and then continued to run the "Acquired Divine Formula".

His spiritual power is now flourishing, and it is the best time to temper his spiritual power into divine thoughts, and the "Acquired Spiritual Formula" is this hammer.

Li Chen only felt that his mind seemed to be filled with an indescribable feeling of swelling at the moment.

After a long time, the swelling suddenly disappeared, because the previous hundredfold spirit was now almost condensed into a small piece.

Li Chen only felt a monstrous humming sound in his mind at this moment, and then the humming gradually calmed down, and finally turned into the rhythmic sound of the waves like the sea.

What followed was an unprecedented sense of pleasure, and a wave of spiritual fluctuations emanated from Li Chen's body, and it spread to the minds of the Heavenly Demon Sect people guarding outside the array, shaking a large number of people for a moment.

"Knowing the sea has been completed, and the divine thought has been completed. Immortal Venerable said lightly.

The sea of knowledge is the sea composed of divine thoughts, and it is the place where immortal cultivators store their divine thoughts.

Li Chen suddenly felt that he could look inward at this moment, he carefully tried to gather his divine thoughts in his sea of consciousness, and finally saw the appearance of Xianzun for the first time, because Xianzun was quietly suspended in his sea of consciousness at the moment.

It turned out that this Ten Thousand Worlds Immortal Venerable was actually a young man, looking almost the same age as Li Chen, and he didn't look like the old man Li Chen imagined at all.

"Immortal cultivators naturally cultivate immortality, and their appearance does not change with age, but with their minds. When the deity was as young as you, he had already entered the innate state, so his appearance never changed again. ”

The Ten Thousand Worlds Immortal Venerable said proudly in Li Chen's mind.

"The master is really a master, and he has already entered the innate at such an age, and the disciple is ashamed. Li Chen said with emotion.

"I was born in the upper plane with a strong aura, and it is naturally outstanding to be able to enter the innate at this age, but like you in this lower plane with a thin aura, you can also cultivate to the middle stage of foundation building at this age, which is even more remarkable, you don't have to be presumptuous. Xianzun shook his head and smiled.

Li Chen nodded slightly, and then withdrew his divine thoughts from his sea of consciousness, and at the same time released them outside.

The invisible power of divine thought enveloped the space around him, turning this place into his mind domain.

Everything in this Mind Domain Li Chen was almost close in front of him, even if it was a disturbance, it would be clearly perceived by Li Chen.

After the divine thought was condensed, Li Chen could be regarded as having a new way of feeling, one more sense than the five senses of ordinary people, commonly known as the sixth sense.

The rich yin qi of this Heavenly Demon Valley turned into a thick black mist in Li Chen's sixth sense at this moment, almost enveloping the interior of the Heavenly Demon Valley, only the aura in his large array was shining with dazzling light.

After the completion of the Nian Domain, Li Chen took the Divine Thoughts back, because he had other things to do now.

"This Heavenly Demon Ape's femur is used to refine a bone sword, and it must be infinitely powerful. ”

Li Chen took out the extra-long femur of the Heavenly Demon Ape that he had collected, and thought to himself.

These bones have been nourished by the Yin Qi absorbed by the Heavenly Demon Ape for hundreds of years, so if they are made into magic weapons, they will naturally contain a strong Yin and evil Qi inside.

This can not only cause physical harm to the other party, but also cause mental damage.

Just like refining the Yunyan Sword before, Li Chen also engraved dense charms on these bones this time.

The spells formed a formation, and the arrays were connected to each other, and these femurs were connected.

Then, Li Chen's divine thought reached out and imprinted a trace of divine thought power in the rune array, so as to ensure that this magic weapon could only be used by him from now on, unless the other party's divine thought was stronger than Li Chen's, enough to erase Li Chen's divine thought imprint.

By the time everything was done, ten days had passed.

Li Chen's mind moved, and the dense runes on these huge femurs lit up at the same time, and then they all shrank suddenly, and then began to deform.

A femur became sharp and became the body of a sword.

One of the femurs became hollow and became a scabbard.

The other femur becomes the hilt and handle of the sword.

Li Chen held this delicate bone sword with jade on his body, and the sword on the scabbard was directly five zhang away, which was three points better than the Yunyan Sword.

As soon as Li Chen's mind moved, the sword was automatically unsheathed, and then it was like a beautiful piece of jade suspended in front of Li Chen.

Then, Li Chen slashed out a sword light at the sky, and the sword light rushed directly to the sky, splitting the clouds above the Heavenly Demon Valley into a sword mark that was hundreds of feet long, revealing the blue sky behind it.

"A sword to cut the clouds, the power is really extraordinary, so let's call you the cloud sword. Li Chen was very satisfied with this effect, so he put away the bone sword.

Li Chen was very relieved at the moment, but what made him even more relieved was that he suddenly felt that his cultivation that had not been moved for a long time suddenly showed signs of promotion.

"Well, this time, the trend will impact the realm of the late stage of foundation building. ”

After that, Li Chen once again entered the cultivation state in the formation.

......

Twenty days later, within the Heavenly Demon Valley Heavenly Demon Great Array, a thin sword suddenly rose into the sky.

"Fulong Sword!Senior Sister Yuyu, you actually successfully used the Fulong Sword just now?" Lu Nan's strange cry came.

Yu Yu had already collapsed, and at this moment the saber fell to the ground, and she quickly meditated cross-legged to recover.

In twenty days, Yu Yu has gone from being comparable to a sword master at the beginning to being comparable to a sword spirit Xiaocheng now!

This kind of progress was already a divine speed, but it was still far from reaching the point of casting the Fulong Sword.

Li Chen only passed on the first three swords of the Nine Swords of Yu Yu Futian.

It's just that just now, Yu Yu seemed to have an understanding, and he actually sensed it by himself, gathered all his spiritual energy and poured it into the sword, and then waved it into the air, and unexpectedly displayed the prototype of the Fulong Sword.

However, just this moment has already overdrawn her strength, if it weren't for the fact that she was deep in the thick aura at this moment, I was afraid that she would have passed out before she had time to meditate.

The release of spiritual energy is the symbol of the Sword King, and Yu Yu is very remarkable when he forcibly uses the Sword Spirit Realm to force it.

Although her sword was far from Li Chen's original sword, it was enough for her to see the shortcut to the Sword King.

"Senior Sister Yuyu, your Fulong Sword has been completed, you can be comparable to the Sword King at that moment!" Lu Nan was full of emotion and walked over to congratulate.

is also cultivating in this formation, Lu Nan's progress is not as obvious as Yu Yu, but he is now only one step away from the completion of the sword spirit.

Yu Yu recovered slightly, took a deep breath, turned his head to look at Li Chen's figure who was still in retreat, shook his head and smiled: "I am still far behind Li Gongzi." ”

After that, a trace of worry flashed in her eyes, and she said silently: "Gongzi Li has been cultivating there for twenty days in a row, I don't know if his body can hold up......

"Haha, what kind of powerful person the master is, don't you know, he'll be fine. Lunan shook his head and smiled.

"I have a hunch that if Li Gongzi goes out of the customs this time, his cultivation will definitely go further, I am afraid that the gap between us will become like heaven and earth like the original ......" Yu Yu bit his lower lip slightly, looked at Li Chen's figure, and said with envy and admiration.
