The conditions under which Li Shiming practiced the 'Secret Book of Heavenly Sound' were so luxurious that even the Six-Fingered Sound Demon didn't have such luxury back then.

During the practice, the third-grade Qingling Mingxin incense was always burning, just to make his mind more peaceful, which was in line with the state of mind for practicing the "Tianyin Secret Book".

He also added a sound barrier inside the magic circle on the top of the mountain to prevent the sound of the piano from affecting his followers.

He is currently unable to use the magic weapon-level guqin, and is still using the 'Earth Sound to Destroy the Dao'. However, he has already mastered the inheritance of the Six-Fingered Sound Demon. The sound of the 'Earth Sound to Destroy the Dao' can kill cultivators in the Foundation Establishment period.

Unfortunately, he did not achieve the state of mind he was pursuing, and the bottleneck in front of him was still as solid as a rock.

After the song of "Destroying Dao" ended, Li Shiming slowly broke away from the influence of the piano music. He stood up with a look of helplessness in his eyes.

The breakthrough of his clone Li Yuanba stimulated him, and the attack of the fake baby on him made him extremely eager to improve his strength.

In this world of immortal cultivation fraught with dangers, without strong power, he dared not even leave the mountain gate.

Other Half-Step Golden Cores were killing people outside, but he could only hide inside the mountain gate. This was related to his identity.

Given his status as a master alchemist, any cultivator who dared to become his enemy was either extremely powerful or had a strong background.

The Shushan Sect even regarded him as their hope for the future. As long as he became a Jindan cultivator, they would be able to provide the sect with higher-level third-grade elixirs and would not let him suffer any danger again.

Li Shiming returned to the cave, where the 'Absolute Spirit Phantom Snake' was coiled in a corner. The high-quality spiritual energy generated by the Pure Spirit Koi and the third-grade golden lotus was the 'Absolute Spirit Phantom Snake's' favorite environment.

However, Li Shiming ignored the high-quality spiritual energy. Now there was no room for improvement in his body.

The spiritual power in the Spirit Lake was almost filled in a physical form. Not only the Spirit Lake, but every part of his body was filled with spiritual power. His physique had reached the extreme.

He didn't even take the fourth-grade 'Tianluo Immortal Milk' he got, because there was no need to do so. Taking it now would only waste the effect of the fourth-grade 'Tianluo Immortal Milk'.

His physical condition benefited from practicing the 'Vajra Body Protection Divine Art' and the 'Sword Demon Secret Book', and he had been taking third-grade spiritual tea and spiritual fruit continuously in recent years. The third-grade spiritual tea and spiritual fruit were already the top-level nourishing spiritual objects for the body in the foundation-building period. After taking a large amount of them, his physical condition was pushed to the extreme.

Therefore, in recent months, he did not even use the third-grade spiritual tea and spiritual fruit. Since he could not leave the mountain, he used his free time to study the "Tianyin Secret Book" and research the knowledge of formations.

He didn't know what the opportunity for his promotion would be, he could only keep trying.

Anyway, whether it is the 'Heavenly Sound Secret Book' or the knowledge of formations, sooner or later you have to study them in depth.

After seeing the spiritual object in the mustard seed ring of Director Feng Yi, his horizons were broadened and his attitude towards the current third-grade spiritual objects was completely different, even though he was still only at the Foundation Establishment stage.

Both the original body Li Shiming and the clone Li Yuanba were in a leisurely state. Such days passed quickly, and another three months were about to pass.

On this day, Li Shiming was playing the guqin in the pavilion, feeling the improvement in his state of mind brought by the sound of the guqin.

But he suddenly interrupted the sound of the piano. Even though this forced interruption would affect the effect of this practice, he still stopped playing the piano.

The divine light disappeared from his eyes, and they looked extremely empty.

However, his mind, through the inexplicable connection with the soul of his clone Li Yuanba, leaped across the long distance and entered the body of his clone Li Yuanba.

Li Yuanba was also forcibly interrupted while practicing. What interrupted him was the sudden violence of the spiritual energy of heaven and earth, which almost made him unable to control the spiritual energy absorbed into his body.

In other words, he is already a Jindan cultivator and his realm is stable, otherwise he would be affected to some extent.

He opened his eyes, and his figure flashed out of the cave, and he casually put away the magic weapon of Wanjian Peak.

He saw He Wei and Liu Gang flying towards him, and the faces of the two Jindan cultivators were full of fear.

Although the strength of these two Jindan cultivators is weak, that is relative. The two Jindan cultivators are Jindan cultivators from a large sect like the Senluo Sect. Although they are a little weak within the sect, their strength is still not weak among the Jindan cultivators in the Northern Shu Continent.

The fact that they showed fear meant that something terrible had happened.

"Junior Brother Li, come with us to control the island protection formation!" He Wei said in panic.

"Why is the spiritual energy so violent?" Li Yuanba asked as he followed the two Jindan cultivators to fly towards the core area of ​​the formation on Zhenbei Island.

"I don't know where the Nascent Soul ancestor came from, but he was in conflict with a fourth-grade sea beast in the sea, and Zhenbei Island was affected by the aftermath of the battle!" Liu Gang replied with a horrified look on his face.

Li Yuanba was extremely shocked. He knew very well why Liu Gang said that it was a Nascent Soul ancestor who came from nowhere, because the Nascent Soul ancestors of the Northern Shu Continent would never fight with a fourth-grade sea beast in the sea.

All the fourth-grade sea beasts around the Northern Shu Continent have signed peace treaties with the Nascent Soul ancestors of the six major sects. They acknowledge each other's existence and will not start a war.

In addition, the world of immortal cultivation has its own rules. The battles of the Nascent Soul ancestors cannot be carried out on the ground. If they want to fight, they can go to the Thirty-Three Heavens, where they will not cause irreparable damage to the earth.

While thinking, the three of them came to the core of the formation.

They came to perform the garrison mission and were given the authority to control the formation here.

Since Li Yuanba was the strongest, He Wei and Liu Gang asked him to sit in the center to preside over the formation, while He Wei and Liu Gang were responsible for coordination.

This was not the time to be humble, Li Yuanba sat at the core center of the formation without any politeness.

Before He Wei and Liu Gang could intervene, his mind and hands moved together, and the formation was mobilized. The originally violent spiritual energy in Zhenbei Island eased down. This was because the formation resisted the influence of the outside world.

"Junior brother, you also study battle formations?" He Wei and Liu Gang looked at each other, and He Wei asked Li Yuanba in disbelief.

He and Liu Gang were just about to take action, but in fact they could no longer intervene after Li Yuanba mobilized the formation.

Li Yuanba was extremely familiar with the formation. The two Jindan cultivators could not keep up with the speed at which Li Yuanba controlled the formation. If they intervened rashly, it might have the opposite effect.

This dealt a heavy blow to He Wei and Liu Gang. They were not as good as Li Yuanba in terms of combat power because Li Yuanba was a sword cultivator. They were not as good as Li Yuanba in terms of magic weapons because Li Yuanba had a good master. Elder Jian was the strongest sword cultivator among the Jindan stage cultivators.

Perhaps Li Yuanba has an extraordinary talent in cultivating silver corpses.

However, Li Yuanba's in-depth research on formations was beyond the imagination of the two Jindan cultivators.

The two Jindan cultivators have been Jindan cultivators for decades, and they have had time to study many immortal cultivation techniques.

Since achieving the Golden Elixir, cultivators have had a relatively long lifespan and have the capital to spend time studying the art of cultivating immortals.

The knowledge of formations is an immortal cultivation skill that any Jindan cultivator must study to some extent. Even if the knowledge of formations is difficult, one must have a certain understanding of it.

But the two Jindan cultivators just couldn't believe it. They had studied formations for decades, but they were not as good as Li Yuanba, a cultivator who had just achieved Jindan.

What they don’t understand even more is how Li Yuanba uses his time.

Li Yuanba had to practice sword skills, sacrifice magic weapons, and refine corpses. Each of these took up a lot of the cultivator's time, but Li Yuanba still had the energy to study the formation, and he studied the formation to such a level.

"I have studied it in my spare time!" Li Yuanba answered while adjusting the formation with a serious expression.

Through the formation, his perception was amplified countless times, allowing him to sense the situation outside Zhenbei Island.

Since the battle took place at a great distance, he could not see the battle between the two Nascent Soul Realm beings, but the increasingly violent spiritual energy and a huge wave a hundred meters high in the distance all indicated the horror of the battle.

Especially the hundred-meter-high wave, which brought with it a heart-pounding momentum. This was not an ordinary wave, but the aftermath of a battle between two Nascent Souls.

He Wei and Liu Gang were at the core of the formation, so they could sense what was happening in the distance and knew that danger was getting closer.

They didn't dare to speak anymore so as not to disturb Li Yuanba. The only thing they could do was to continuously input their spiritual power into the core of the formation in order to increase the power of the formation even a little bit.

Li Yuanba was not fighting alone at this time. His original body, Li Shiming, had noticed the trouble here and had already turned his mind over to take over the control of the formation.

It only took three breaths of time. Being at the core of the formation and having sufficient authority, Li Shiming quickly became deeply familiar with the formation.

The effect of a formation will be completely different when it is controlled by a cultivator who is infinitely close to a formation master and when it is controlled by several laymen.

Under the sea, wherever the hundred-meter-high waves passed, some low-level sea beasts or ordinary fish were all smashed into pieces by the waves.

The powerful force contained in the hundred-meter-high wave frightened Li Shiming, who was close to Li Yuanba's body.

If it weren't for the existence of the formation here, he would have already controlled his clone Li Yuanba to use "Lotus Step by Step" to escape thousands of miles away.

Some intelligent sea beasts in the sea dived to the bottom of the sea to avoid the disaster.

The ruthless waves swept across, and the few unlucky foundation-building monks who were out on the move were hit by the waves and turned into blood mist and disappeared with despair in their eyes.

The monks on Zhenbei Island stared at the sea outside the formation as if they were waiting for the end of the world.

The breath of death enveloped the entire Zhenbei Island. Their only hope was that the three Jindan monks could guard the island's formation.

The monks did not flee because they had no way to escape.

The speed of the huge waves is much faster than the flying speed of the cultivators. Not many cultivators can master extremely fast flying speed during the foundation-building period.

Instead of running away, it is better to stay in the formation.

The huge waves hit the formation, and the formation of Zhenbei Island emitted a dazzling light. The monks saw that the shield outside the island was revealed by the impact of the huge waves.

The patterns on the formation shield flickered, and the entire formation shield kept wriggling, so that the impact force brought by the huge waves was reduced and guided by this wriggling.

The huge wave that hit the formation shield broke, but the formation shield did not break.

The monks on the island couldn't help but howl in excitement; they survived.

The cultivators among them who had studied formations realized that the reason the formation could withstand the impact of huge waves was largely due to the intervention of a formation master who was extremely knowledgeable about formations.

But what they didn’t know was what extreme operations Li Shiming performed in such a short period of time.

He Wei and Liu Gang looked at Li Yuanba in amazement. They had just seen Li Yuanba's mind and hands working together continuously. At the moment before the huge wave hit the formation shield, he issued hundreds of commands to the formation.

Hundreds of instructions made the formation shield come alive, neutralizing the impact of the huge waves into nothingness.

"There are still huge waves!" Before they could be happy for long, He Wei exclaimed in surprise.

Within the range that the formation could perceive, fifteen huge waves were rushing towards Zhenbei Island, and each wave was more powerful than the previous one.

He Wei's face looked grim; he could almost imagine what he was going to face.

Their garrison mission has not yet ended, so they cannot leave Zhenbei Island.

But now He Wei and Liu Gang both wanted to leave, because they couldn't believe that the formation of Zhenbei Island could withstand the next fifteen huge waves.

That was not a huge wave, it was clearly the shock wave caused by the battle between the Nascent Souls. Although the shock wave continued to release its own energy along the way due to the long distance, it was still not something that the Zhenbei Island formation could withstand.

"My two senior brothers, please input your spiritual power with all your strength!" Li Yuanba's voice was deep and powerful, and one could hear the confidence in his voice.

The person who spoke was Li Yuanba, but in fact it was the order from the real body Li Shiming.

Li Shiming completely merged with the formation through Li Yuanba's body and mind. IBM z15 even mobilized all the CPUs and added calculations to control the formation.

"Follow my junior brother's instructions!" He Wei and Liu Gang gritted their teeth and said in unison.

In the world of immortal cultivation, the strong are respected, and the capable are also respected. Li Yuanba has both strength and ability, so his two fellow disciples will naturally obey his orders when there is no other way.

Fifteen huge waves came very quickly. The monks on the island who were cheering and feeling lucky for being alive saw the continuous huge waves, and the power carried by the waves overwhelmed them.

Some of the monks were confused, some were crying, some were crazy, some were upset, and so on.

Faced with the approaching death, except for a few determined monks, the rest of the monks were filled with despair.

Li Shiming sensed the power of the huge waves. Any one of the fifteen huge waves had a power that exceeded the full-strength attack of a peak Jindan master.

The formation here might be able to withstand a full-strength attack from a peak Jindan cultivator under normal circumstances, but fifteen consecutive full-strength attacks from a peak Jindan cultivator would be something the formation would definitely not be able to withstand.

But that was without his control. With his control, the situation would be very different.
