Zilong Lake is located in a continuous mountain in the northwest of Tianyu, although the area of Zilong Lake is not large, but because there is a purple dragon living in Zilong Lake, few Tianyu masters dare to approach Zilong Lake.

At that time, Wuwen Taishi, the Taishi of the Great Qian Dynasty, once came to Zilong Lake and wanted to forcibly subdue Zilong, but although he successfully injured Zilong, in Zilong Lake, he could not subdue Zilong, and after several attempts, he finally gave up.

"Great Demon King, can you feel the location of the purple dragon in the purple dragon lake?" After about five days of hurrying, Yun Tianyu passed through the mountains and came to the top of the Zilong Lake embedded in the center of the mountain range, looking down at the entire rippling lake.

"Well, there is a prohibition in this Purple Dragon Lake, which actually hinders the penetration of my soul. "When the Great Demon King released a powerful soul power to infiltrate the Purple Dragon Lake, he found that the Purple Dragon Lake was filled with a powerful prohibition, hindering his soul penetration and unable to lock the Purple Dragon in the lake.

"Is there a ban in Zilong Lake?could it be that Zilong laid it himself?" Yun Tianyu frowned slightly, and silently thought in his heart in confusion.

Just when Yun Tianyu was puzzled, the Great Demon King noticed that Yue Qingchen, Ba Jinrong and the other four had arrived one after another, although Yun Tianyu wanted to kill the four of them immediately, but thinking that if the four of them died, it was likely to bring trouble to Nalan Xuan, so he had to hold back the killing intent in his heart, and covered his breath with the help of the space-time dream, and observed the actions of the four people.

And before the arrival of the four of them, the Great Demon King released his soul and condensed the Dao Soul Silk that permeated the Zilong Lake, and when Yue Qingchen flew to the Zilong Lake, he did not immediately go deep into the Zilong Lake, but observed around the Zilong Lake.

After observing for a day or so, Wen Changzhen, a fourth-level True Immortal Realm, was the first to walk into Zilong Lake, and quickly dived under Zilong Lake to find the dragon grass growing under Zilong Lake.

Yue Qingchen, who was lurking around Zilong Lake, saw that Wen Changzhen was the first to go deep into Zilong Lake, and gradually lost their breath, and entered Zilong Lake one after another, and cautiously dived under Zilong Lake.

When the four of them went deep into Zilong Lake together, their bodies were contaminated with the soul silk condensed in advance by the Great Demon King to varying degrees, and their every move was completely under the supervision of the Great Demon King.

"Okay Tianyu, it's almost over, let's go deep into Zilong Lake. Just one hour after Yue Qingchen and the four of them went deep into Zilong Lake, the voice of the Great Demon King sounded in his mind.

"Okay!" Yun Tianyu nodded, controlled the space-time dream to cover his breath, and cautiously sneaked into the Purple Dragon Lake.

"It's so cold lake water!" Entering Zilong Lake, Yun Tianyu immediately felt that the water of Zilong Lake was cold and biting, and a large amount of cold air penetrated through his skin and continued to burrow into his body.

And as the distance deepened, Yun Tianyu felt that his strength had been suppressed, and the weather origin particles in his body fluctuated violently.

"Tian Yu, the Origin Space-Time Technique you have cultivated is beyond the Immortal Technique, and you try to control the prohibition in the Weather Origin Particles devouring the lake water, you should be able to break the prohibition in the lake water. Feeling that Yun Tianyu's strength had been suppressed, the voice of the Great Demon King immediately sounded in his mind, admonishing.

"Okay!" Yun Tianyu took a deep breath, ran the Origin Space-Time Technique at high speed, and controlled the three thousand five hundred Weather Origin Particles in his body to release a powerful devouring power, frantically devouring the forbidden power that invaded his body.

Under the frenzied devouring of the weather origin particles, the prohibition in Yun Tianyu's body quickly disappeared, and he returned to the strength of the third-level True Immortal Realm, and continued to dive into the Purple Dragon Lake, looking for the Dragon Grass.

"Tianyu, pay attention, I feel that a water monster with good strength is slowly approaching you. Just when Yun Tianyu quickly dived more than a thousand meters, the soul power released by the Great Demon King sensed the danger and immediately transmitted the voice to tell Yun Tianyu to be careful.

"It's not the purple dragon. Hearing the transmission of the Great Demon King's intentions, Yun Tianyu immediately became alert, and the transmission asked.

"It's not that purple dragon, it's a water monster comparable to the third-level True Immortal Realm. As the water monster got closer and closer, the Great Demon King probed its reality.

"It's good if it's not a purple dragon!" Knowing that it was just a third-level true immortal realm water monster approaching, Yun Tianyu put his mind at ease, and with a move of his mind, he sacrificed the Bagua Instrument Array.

"Huh!" Yun Tianyu had just summoned the Bagua Array when an extremely fast black shadow appeared in front of him, opening its blood basin and biting him.

"Rule power, forbidden!" Yun Tianyu saw that the black shadow that suddenly appeared was a strange fish with a body length of more than five meters, a pitch-black body, and a pair of tentacles on its forehead, and immediately burst out with rule power to ban it.

When Yun Tianyu forcibly banned the strange fish for a second, the Bagua Array fell from the sky, trapping the strange fish comparable to the third-level True Immortal Realm in the array.

Immediately afterwards, the Bagua Array was activated, and a large number of golden light immortal weapons surrounded the strange fish, attacking quickly and damaging the body of the strange fish.

"Weather Origin Particles, Injection!" When the Bagua Weapon Array attacked the strange fish, Yun Tianyu clearly felt that the defense of the scales of the monster fish's body was extremely terrifying, and constantly resisted the attack of the Golden Light Immortal Weapon, and immediately injected the Weather Origin Particles into the Bagua Array to enhance the power of the Bagua Instrument Array.

Under the injection of three thousand five hundred Weather Origin Particles, the power of the Bagua Instrument Array continued to increase, and it began to deeply damage the body of the strange fish, and soon blurred the flesh and blood that pierced its body.

As his body injuries continued to worsen, the strange fish went crazy, desperately attacking the Bagua Array, trying to break out.

However, the power of the Bagua Weapon Array infused with 3,500 Weather Origin Particles was too terrifying, and the strange fish whose body injuries were becoming more and more serious could not break free at all, and was soon pierced through the body by the Bagua Instrument Array and died, leaving behind a beast pill full of cracks.

"Soul Eater Brain, Devour!" The Monster Fish Beast Pill was exposed, and Yun Tianyu immediately sacrificed the Soul Eater Brain and controlled the Soul Eater Brain to devour the Monster Fish's Beast Pill.

Yun Tianyu controlled the Bagua Array to kill a strange fish comparable to the third-level True Immortal Realm, and Yue Qingchen, Ba Jinrong and the others were also attacked by powerful immortal beasts in Zilong Lake.

However, they all have strong hole cards, but their strength is not bad, and it didn't take much effort to kill the fairy beasts in the lake they encountered.

"Yin!" Just when Yun Tianyu and the five people killed the five immortal beasts in the lake respectively, and a large amount of blood was diffused, a deafening dragon groan came from the bottom of the bottomless Purple Dragon Lake, and the powerful roar shook the souls of the five Yun Tianyu people.

"It's not good, the purple dragon that inhabits Zilong Lake smells blood and wakes up, Tianyu, quickly go to the edge of the pool and hide. Hearing the powerful roar of the purple dragon, the Great Demon King immediately sent a voice and urged.

"Okay!" In fact, before the Great Demon King reminded him, Yun Tianyu, who sensed the crisis, summoned the wings of Jinpeng and flew to the edge of the pool at a very fast speed, reining in his breath and hiding it.

"Tianyu, that Wen Changzheng seems to have been discovered by Zilong, and now he is on the run. "Just when Yun Tianyu was hiding and dodging, the Great Demon King sensed that Ba Jinrong was now being chased and killed by a terrifying immortal beast through the soul silk he released earlier, and the situation was very dangerous.

"Wen Changzheng was chased and killed by Zilong, it was best if he died!" the corners of Yun Tianyu's mouth turned up slightly, and the gloating voice responded.

"By the way, the Great Demon King, now that the purple dragon has awakened, can you perceive the strength of that purple dragon through the forbidden lake?" Yun Tianyu asked.

"If I feel good, that purple dragon's strength is comparable to that of a sixth-level true immortal, plus it has the blood of a divine beast flowing in its body, it should be able to compete with a seventh-level true immortal master. The Great Demon King released a powerful soul power and sensed it, and said in a voice.

"That purple dragon's strength is so terrifying, if we want to face it, there is only one way to escape. Knowing Zilong's strength, Yun Tianyu couldn't help but feel a huge pressure.

"Well, if you encounter that purple dragon, even if I help you, I can only help you escape, but Tianyu, if you really can't get rid of the purple dragon's pursuit, you have a treasure on you that can deter the purple dragon and win the opportunity to escape. The Great Demon King said.

"What treasure!" Yun Tianyu raised his eyebrows and asked softly.

"It's Wuwen Taishi's order. I feel that there are three terrifying energies sealed in that token, and if you can release the token energy, it will be enough to deter that purple dragon. The Great Demon King informed.

"Wuwen Taishi Ling! By the way, the Great Demon King, you once fought against Wuwen Taishi, what kind of realm master is he?" Yun Tianyu asked curiously.

"Master Wuwen should not be a sixth-level true immortal master as rumored, he should be a genuine seventh-level true immortal master, and now that he has obtained two-thirds of the power of the immortal core, it is estimated that he is very likely to break through the seventh-level true immortal and become an immortal. The Great Demon King speculated.

"It is possible for Wuwen Taishi to break through to the seventh level of true immortals and become an immortal!"

"Great Demon King, if Master Wuwen becomes an immortal, then he will not ascend to the Immortal Realm, will he still stay in the Heavenly Domain?" Yun Tianyu continued to transmit his voice and asked.

"That Wuwen Taishi is the same as your father, it's not simple. Therefore, he is unwilling to ascend to the immortal realm, and the immortal realm should not be able to summon him away. "The Great Demon King has revealed a great secret path.

"Master Wuwen is not as simple as my father. Great Demon King, do you know my father, who is he, where is he now?" Yun Tianyu asked excitedly with a move in his heart.

"This! Since you want to know, I'll reveal some of your father's secrets!Tianyu, do you know why the space-time dream is on you?" the Great Demon King took a deep breath and asked Chuanyin.

"Could it be that my father gave it to me?" Yun Tianyu guessed.

"Yes, the Spacetime Dream was given to you by your father. When I was in my prime, I once fought with your father for the space-time dream, but in the end, I lost to your father, not only lost the space-time dream, but also made your father suppress my holy core in the space-time dream and became the guardian of the space-time dream. The Great Demon King revealed a big secret to Yun Tianyu again.

"Your Holy Core was sealed by my father, my father is so powerful!" Yun Tianyu asked in disbelief.

"Your father was indeed terrible back then, but he was also killed because of the space-time dream and was reborn in this heavenly domain. As for what state your father reached back then, when you help me unravel the Holy Core Suppression, I will tell you, and you don't need to know it now. Just when Yun Tianyu wanted to continue asking, the Great Demon King stopped revealing the secret.

At this moment, three violent blasting sounds suddenly came from Zilong Lake, shaking the icy and biting water of the lake and fluctuating violently.
