I exchanged sects with the real daughter, and I ascended to heaven to offer sacrifices to her

Ye Qingning thought to himself that since the hidden mission had arrived, there was no time to hesitate.

He immediately used the art of spiritual concealment, followed the sound, and shuttled through the fierce battlefield like a ghost, arriving at the edge of the ice field.

She had just noticed that in addition to Shen Xuanli, there was another person in the Spirit Severing Stage and two people in the Out-of-Body Stage on the battlefield. In just a short while, four people had been eliminated.

Among them were also disciples from Penglai, who probably didn’t even know how they were eliminated after being eliminated.

The remaining four people are all more powerful than her, which is enough to show how exciting the current fight is and it may end at any time.

The purpose of hiding the spiritual consciousness is to avoid alerting others and exposing the whereabouts.

Ye Qingning followed the sound, but the strange sound seemed to have some kind of magic. It was sometimes far away, sometimes near, sometimes strong, sometimes weak, making it difficult to determine the exact location.

In theory, a cultivator's spiritual sense can penetrate water and explore the scene under the sea, but when Ye Qingning used his spiritual sense to explore the situation under the sea, his spiritual sense encountered an obstacle.

This also made Ye Qingning conclude that it was some unusual power hidden under the sea that hindered her spiritual sense from detecting.

Without thinking too much, Ye Qingning dived into the freezing cold sea water.

Fortunately, Ye Qingning had previously formed a bond with the Frost Moon Mirror, so his consciousness was not eroded by the cold. If it were any other cultivator, this kind of cold that penetrated deep into the bone marrow would probably freeze even their consciousness.

The sea water was as black as ink, bottomless, swallowed by darkness, and not a trace of light could be seen.

Although Ye Qingning's spiritual sense was blocked and he could not explore, he could still sense some strange-looking marine creatures moving around in the darkness.

Staying alert, Ye Qingning continued to dive, and the strange sound seemed to become clearer.

As he got closer to the source of the sound, Ye Qingning finally discovered an ancient and dilapidated altar in the dim seabed.

There were faint fluctuations of spiritual energy around the altar, and the stones were covered with traces of erosion by sea water.

In the very center, a faint light was faintly visible, standing out in the pitch-black silence.

The strange chanting sounds came from here.

Ye Qingning originally thought that it might be a strange sound made by a species similar to the mermaid, but now it seems that she was wrong.

As soon as he stepped onto the edge of the altar, a powerful spiritual power wave burst out from the center of the altar and spread to the surroundings.

It was like a warning that someone was intruding.

If Ye Qingning had not had a strong sense of awareness and was not on guard, he would have been almost knocked back by this sudden force.

At the same time, a ray of light burst out, and an ancient rune array appeared in the center of the altar. The runes flowed, seeming to resonate with the strange chanting.

Ye Qingning's heart trembled. He didn't expect that the strange sound came from the sonic array arranged in the center of the underwater altar.

Before, when he was in the inner sect, Ye Qingning went to the school to take the basic formation class, and also read a lot of books about formations. He had some understanding of the sound wave formation.

As the name suggests, the sonic formation is a formation that attacks with sonic waves.

Use sound waves to interfere with, control, or attack spiritual consciousness.

It is one of the most difficult formations to guard against, because you don't know when and where you will be attacked by sonic waves. Once you fall into it, it is like being stuck in a quagmire and it is difficult to save yourself.

Ye Qingning stepped forward, trying to destroy the formation and the source of the sound waves, but was interrupted by a sudden shock.

The sea water was churning violently, as if something was approaching, and a strong sense of threat surged from all directions.

A huge shadow was approaching rapidly, and Ye Qingning's first reaction was - a giant underwater monster!

Ye Qingning's eyes were as sharp as a torch, and he quickly caught sight of the approaching monster in the turbulent sea.

The monster's body was as huge as a mountain, covered with dark scales, and it shone coldly in the sea water. Every time its huge tail swung in the sea water, it seemed to shake the entire seabed.

A pair of eyes were like two lanterns, staring at Ye Qingning intently, obviously regarding Ye Qingning as prey.

Ye Qingning's heart trembled, and he recognized that the giant sea beast in front of him was the water monster Black Dragon Whale.

The black dragon whale is huge in size, and its scales are extremely strong and difficult to penetrate like iron armor.

The Black Dragon Whale in front of him had the strength equivalent to the peak of the Spirit Severing Stage.

Among cultivators and monsters at the same level, the monsters are naturally more powerful. After all, monsters have thick skin and flesh, and possess powerful physiques and strength. Their physical strength is beyond the reach of cultivators.

Even the giant fire python before was not as powerful as the black dragon whale in front of him.

The next second, the Black Dragon Whale opened its huge mouth, which was big enough to swallow a ship, revealing its sharp fangs, swung its tail, and pounced towards Ye Qingning.

Ye Qingning stretched his body and narrowly avoided the fatal blow of the Black Dragon Whale. He also knew that although his spiritual awareness was superior to that of the Nascent Soul, his chances of winning against a Black Dragon Whale of such strength were not great.

The key point is that no one can guarantee that there is only one Black Dragon Whale on the seabed. If another one comes later, two deep-sea monsters with the strength of the Spirit Severing Stage will be even more difficult to deal with.

If she couldn't kill it, she could only outsmart it. The hidden mission was to destroy the source of the sound, and she wasn't asked to kill the Black Dragon Whale.

In this case, she only needs to avoid the attack of the Black Dragon Whale and try to destroy the sonic formation to complete the mission successfully.

Ye Qingning had a plan in mind and launched a counterattack to deal with the Black Dragon Whale.

With the Frost Moon Mirror, Ye Qingning's spiritual sense was extremely flexible in the sea water, and he could cleverly avoid the fierce attacks of the Black Dragon Whale every time.

The Black Dragon Whale roared continuously, and its huge body caused huge waves in the sea. Every attack made the sea water boil.

As time went by, the Black Dragon Whale became increasingly violent, and even the underwater altar was shaken and could collapse at any time.

Ye Qingning, however, was looking for the core position of the sonic formation in every counterattack and evasion.

The core of a sound wave formation like this is made of a special sound stone.

This sound stone is made of a special material. As the cornerstone of the formation, it can absorb and amplify sound. It is the power source of the sound wave formation and the key to its operation.

As long as the base of the array is found and the sound stone is destroyed, the sonic array will lose its effectiveness and the hidden mission can be completed.

The Black Dragon Whale became more and more violent, swinging its huge tail and forming a visible whirlpool around it.

Ye Qingning kept changing his position and dealing with the Black Dragon Whale. Finally, in the gap between the Black Dragon Whale's attacks, his spiritual consciousness turned into a sharp sword and pointed directly at the Black Dragon Whale's lantern-like eyes.

This stab was like a dragon emerging from the sea, concentrating almost all the power of spiritual consciousness into this strike.

"Roar!"

The Black Dragon Whale let out a deafening roar, and Ye Qingning's spiritual consciousness transformed into a sharp sword that directly pierced through the Black Dragon Whale's thick eyelids.

He also locked onto the position of the array base amidst the angry roar of the Black Dragon Whale and quickly rushed towards the core of the sonic array.

However, the Black Dragon Whale was very powerful, and the vitality and recovery ability of the monster were extremely amazing. In just a moment, it roared and swung its tail, approaching and attacking Ye Qingning!
