Facing the palm print that was as terrifying as a mountain pressing down on his head, Yu Kai's face instantly became as solemn as iron, but his eyes became more determined, revealing an unyielding determination.

He didn't dare slack off, merging with the mecha at top speed. In an instant, a tremendous force surged into his body, causing the aura around him to surge suddenly, like a volcano about to erupt.

At the same time, he tried his best to mobilize all the pseudo-god power in his body and shouted loudly: "Reincarnation Burial Heaven!"

With this earth-shaking shout, the rich, almost tangible power of samsara within the underworld was instantly mobilized, as if the entire ancient foundation of the underworld had been awakened and utilized by him at this moment. The sword light instantly became incomparably more powerful, like a thread capable of tearing through heaven and earth, and rushed towards the palm print.

"Boom!" The sword light and the palm print collided fiercely, erupting with a deafening roar. The powerful energy wave was like a nuclear bomb explosion, instantly sending Yu Kai flying.

He rolled uncontrollably in the air, coughing up blood, which drew sad yet tragic arcs in the air.

However, he did not give up. Instead, he took advantage of this huge energy impact and crashed into the restricted area like a meteor.

"Damn it!" Upon seeing this, a look of extreme anger flashed across the face of the Emperor of Fengdu. He flashed and rushed directly towards the restricted area.

Taiyi Jiuku Tianzun and Ksitigarbha Bodhisattva were equally wary. That place was too important to the underworld, and no mistakes could be made. They instantly transformed into two streaks of light, following closely behind the Emperor of Fengdu.

"Where is he?" As soon as Emperor Fengdu entered the restricted area, he immediately spread out his spiritual thoughts and searched around for Yu Kai's traces like a fine spider silk, but found nothing, as if Yu Kai had disappeared out of thin air.

Taiyi Jiuku Tianzun was horrified and couldn't help but shout, "Yu Kai!" He was filled with worry, fearing that Yu Kai would be accidentally killed by Fengdu Emperor. After all, Yu Kai was only at the mid-stage of the Great Emperor, while Fengdu Emperor had been a peak Dao Emperor for many years. His strength was unfathomable. If he really wanted to kill him, Yu Kai would be hard to resist.

"Amitabha! I hope that my soul and body will not be destroyed!" Ksitigarbha Bodhisattva has a solemn appearance, and his whole body exudes a rich and soft Buddha light, but his voice can't help but carry a hint of worry.

"Impossible, I didn't use my full strength!" Although Emperor Fengdu said this with a look of disbelief on his face, he couldn't help feeling a little uneasy in his heart when he said this.

After all, he had just attacked in anger. If he had really killed Yu Kai, what would he do if the Devouring Emperor came looking for him? His brows knitted tightly together, like a twist of dough. He once again spread his spiritual power and searched the entire Netherworld carefully, but still found nothing.

In desperation, he summoned the Book of Life and Death from the hands of the Ten Kings of Hell, injected spiritual power into it, and immediately investigated Yu Kai's information.

Seeing his frown and serious expression, Taiyi Jiuku Tianzun knew that things had developed beyond his expectations. He hurriedly looked at Ksitigarbha Bodhisattva and said, "Bodhisattva! Please call Di Ting to see where Yu Kai has hidden himself!"

"Yes, summon it!" Fengdu Emperor also seemed to see a glimmer of hope. He took back the Book of Life and Death and returned it to the Ten Kings of Hell. He turned to look at Taiyi Jiuku Tianzun and asked, "Why is there no record of Yu Kai in this Book of Life and Death?"

"Perhaps it's because he is from another fairyland and his name is not recorded in this Book of Life and Death!" Taiyi Rescuer of Sufferings hurriedly explained.

"Yes, that should be the case. He is definitely not dead. This kid has so much luck and power, how can he die so easily!" The Emperor of Fengdu exhaled, breathed a sigh of relief, and looked at Di Ting who was rushing over quickly.

Di Ting, with a tiger's head and a single horn, dog ears, a dragon's body, a lion's tail, and the feet of a unicorn, possesses a peculiar appearance: a dragon, but not a dragon, a tiger, a lion, a unicorn, and a dog. It possesses a perceptive power comparable to that of a Saint Emperor, able to hear sounds from all directions and perceive subtle details imperceptible to ordinary people. Before Di Ting could even begin to salute, the Emperor of Fengdu urgently urged, "Stop saluting! Go and see where Yu Kai has gone."

"Yes! Your Majesty!" Di Ting responded quickly, his ears moving nimbly. He closed his eyes and listened intently to the changes around him, listening very carefully and attentively.

After a long time, it slowly opened its eyes.

"How is it?" Fengdu Emperor, Taiyi Rescuer of Sufferings and Ksitigarbha Bodhisattva looked at it almost at the same time, their eyes full of anticipation.

"Reporting to the Emperor! Yu Kai should not have left the underworld. There is no fluctuation of space breaking in the entire underworld!" Di Ting analyzed seriously.

"I know this too, but the key lies with others." Emperor Fengdu was a little impatient and slightly angry, and his tone became stern.

"Emperor, calm down!" Di Ting was frightened and said hurriedly, "Another possibility is that he has entered the Netherworld Root Vein, and the little beast can't detect him!"

"This is impossible. The root veins of the Netherworld were born from the underground tunnel. Even the Mother Earth cannot step into it. How could Yu Kai possibly get in!" The Emperor of Fengdu suddenly shook his pressure, and a powerful force directly shook Di Ting away.

Ksitigarbha Bodhisattva quickly intervened, emitting a beam of Buddha light, and steadily caught the bleeding Di Ting. Although somewhat displeased, he considered that since the Earth Mother was absent and Fengdu Emperor was the ruler of the underworld, he let it slide. He quickly treated Di Ting's injuries, which made him feel much better.

"Are there any other possibilities?" Taiyi Jiuku Tianzun stepped forward and asked softly.

"I dare not make random guesses about this little beast!" Di Ting was still in shock and was afraid of saying something wrong again.

Suddenly, it seemed to have thought of something, looked at Taiyi Jiuku Tianzun and said, "Perhaps Jiuling Yuansheng knows something?"

"He, what can he know?" Taiyi Jiuku Tianzun and Fengdu Emperor both looked at it with confusion.

"He once said that Yu Kai was killed by him, but somehow he was resurrected here!" Di Ting said timidly, not daring to look at the King of Fengdu.

"Uh! There is such a thing?" The Emperor of Fengdu turned his head and looked at Taiyi Rescuer of Sufferings.

"I've heard about this. It seems that he was injured by the power that erupted from the Netherworld Root Vein at that time!" Taiyi Jiuku Tianzun also recalled.

Without saying a word, the Emperor of Fengdu stretched out a giant hand that covered the sky and grabbed towards where Jiuling Yuansheng was.

Seeing the energy fluctuations gradually subside, Jiuling Yuansheng walked out of the cave. He shook his nine lion heads and stared upward, wondering what had happened and why Di Ting had been called away.

At this moment, a giant hand that covered the sky grabbed towards it like a mountain, and the surrounding void was instantly blocked tightly. It wanted to dodge but it was too late and was directly grasped by the giant hand.
