As the muffled sounds in the earth kept coming, the spiritual energy around the world was thinking about the gathering of the basin. The spiritual energy in the basin exceeded the most abundant place in Xuanzong's spiritual energy in a few minutes.

With a click, Su Yun finally saw a crack crack on the ground in the middle of the canyon. With the appearance of the crack, the spiritual energy in the entire canyon was actually wandering in an extremely strange pattern.

When Su Yun saw the spiritual energy that was like countless little snakes wandering, Su Yun narrowed her eyes, and at the same time, the power of the soul slowly emitted, recording every spiritual energy wandering route in her mind.

"Well, what is Su Yun doing?"

Suddenly, he noticed that Su Yun's unusual mysterious formation suddenly asked, and the Kuai Buhui and other elders in the air also looked at Su Yun. When he felt Su Yun using his spiritual energy to feel the wandering spiritual energy, the elders were quite puzzled.

"Senior Dragon Turtle, Senior Dragon Turtle, come and see what these are!"

In the Gate of Underworld, Su Yun used his heart and used his own heart to condense an illusory soul body. The dragon turtle, who was lying in the pool of life he dug out, said lazily: "I want to sleep, don't disturb me."

Su Yun said angrily: "Come and see this thing, it's like a sealing formation, with a dragon sealing here."

"What?"

When the lazy dragon turtle heard Su Yun's words, his eyes suddenly lit up, and his body flashed and came to Su Yun's phantom in the air. At the same time, the dragon turtle also called Old Yu and Old Ding to come to the air together.

The dragon turtle said excitedly: "What formation? Take out the block and see!"

Su Yun closed his eyes, and the soul power outlined all the spiritual routes that the spiritual energy wandered in the basin with white clouds.

"This is……"

Just after a glance, Old Yu and Old Ding narrowed their eyes, and they instantly entered the state. Dragon Turtle's old eyes also narrowed.

After about two minutes, the dragon turtle emitted a cold aura: "Hmph! It turns out it's this evil beast!"

Su Yun was shocked and asked, "Senior, do you see what this thing is?"

Long Gui sneered and said, "This seal comes from my hands. How could I not see it?"

Su Yun was shocked, and even Mr. Yu and Mr. Ding turned their heads to look at Long Turtle in surprise.

The dragon turtle continued, "Let me first talk about how you encountered this formation!"

Su Yun roughly told the story of the Black Dragon Pond, and the Dragon Turtle chuckled and said, "This Black Dragon Supreme's method is really good! You feel good, but there is a dragon sealed underneath, and it is a magic dragon named Black Dragon Supreme."

"I sealed it back then, but I didn't expect that the demon dragon would slowly crack the seal with this method. According to what you said, this seal is probably becoming extremely weak. The Black Dragon Supreme should be about to crack the seal. It just so happened that you can pass through the seal after entering the Black Dragon Pond. Then you let me come out and completely solve this anti-dragon!"

When Su Yun heard this secret, he seemed extremely surprised. However, Old Yu and Old Ding did not show any strange expressions. Su Yun probably had heard of this.

"By the way, what is the name of this seal formation for senior? It feels so powerful."

The dragon turtle threw a jade talisman to Su Yun directly, then turned around and left: "Come and call me after you enter the formation."

Su Yun took his mind back from the gate of the underworld, and there was a jade talisman in his hand.

"Dragon and Phoenix Seal! Tsk, the seal specially sealed the dragon and phoenix demon, so powerful!"

Afterwards, Su Yun did not pay attention to the Black Dragon Pond, but began to concentrate on ingesting the Dragon and Phoenix Seal.

After Su Yun comprehended the Dragon and Phoenix Seal, the spiritual energy of heaven and earth surged wildly and contracted into the cracks on the ground. As these spiritual energy were sucked in, the cracks became more and more dense.

When the elder of Yixuan Sect saw this, he couldn't help but say, "Tsk tsk, this time the competition is stronger than before!"

The leader's urging Buying frowned slightly when he heard this, and felt a little bad in his heart. Then, the urging Buying looked at Su Yun, but saw Su Yun sitting cross-legged on the ground, as if he was meditating on something again.

"Let the rest of the sect be careful. For some reason, I feel a bad feeling today."

When the people with him heard Su Yun's words, they looked different. Some had serious expressions, while others were disdainful and urged Bubu to see this, and didn't say much. After all, not everyone in the sect listened to Su Yun.

More than an hour passed, the spiritual energy between heaven and earth stopped surging, and the rumbling sound under the ground gradually stopped.

"The Black Dragon Pond is about to open, everyone is ready to go down."

When the urging voice came, Su Yun slowly opened his eyes, and then he saw streams of dark green liquid gushing out from the cracks on the ground.

In less than ten minutes, a small lake was formed, but the water that emerged did not stop and the water level was still rising.

"It seems that the seal is much looser! If the water overflows the surrounding mountains, the seal will completely fail!"

Su Yun murmured to himself, and the dark green lake water slowly stopped when it was a few meters away from the gap in the mountain peak.

"What are you waiting for? This is your great opportunity. This Black Dragon Pond is unprecedentedly broad!"

When an elder spoke, Su Yun saw a disciple falling directly into the Black Dragon Pond, pursuing the technique cross-legged, and began to practice. But the next moment, Su Yun saw that the disciple who fell into the water had become distorted due to the pain.

"ah!"

Screams finally couldn't help but scream. When the people from the Sword Immortal Sect saw this scene, their expressions on their faces became unstable.

"Senior Brother, this..."

Su Yun smiled and said, "The pain of body refining is the pain that penetrates the bone marrow, but if you can bear it, you will benefit greatly. By the way, if you find something wrong with the Black Dragon Pond later, you will leave immediately, do you know?"

Xue Zhenhua and others were slightly stunned for a moment. I don’t know why Su Yun wanted to say this last inexplicable sentence, but Su Yun explained that they would do it.

"Let's go!"

Su Yun stood up, but grabbed Linglong, gave each of them a jade bottle and said, "Remember what I said, if something abnormal happens in the Black Dragon Pond, do you know immediately?"

Little Linglong nodded, and Little Linglong raised the jade bottle in her hand and said, "Young Master is so nice!"

Su Yun smiled and signaled that they could go in, and because Su Yun gave a few more words, the people from the Sword Immortal Sect became the last one to enter the Black Dragon Pond.
