The disciples' shock!

Another half hour passed, and the second Lightning Tribulation was over. Lin Ye also used the Heavenly Demon Lightning Sealing Pearl to seal the power of this second Lightning Tribulation.

Then, the third Lightning Tribulation descended, covering an even larger area.

"Ah!"

Yang Yang let out a scream. The power of the third Lightning Tribulation too terrifying. Even a wisp of it made him feel as if he were facing unimaginable torture.

Chu He, on the other hand, calmly walked in and endured the tempering of the third Lightning Tribulation. He gritted his teeth and persevered without uttering a sound. He was already used to this kind of pain. In terms of endurance, he was comparable to his senior brother Ye Chen. However, Ye Chen did not have his physical body and recovery ability, so he naturally did not dare to use the power of the Lightning Tribulation to temper his body rashly.

Soon, the time for the third Lightning Tribulation arrived, Lin Ye sealed the power of the third Lightning Tribulation once again.

When the fourth Lightning Tribulation arrived, its power increased by another third. At this point, Yang Yang still wanted to absorb and refine the power of the fourth Lightning Tribulation, but he was severely injured and could not recover in a short time.

Chu He could still hold on, but he let out a painful groan. His body was like charcoal, with pieces of charcoal-like skin falling off, new skin growing back, turning into charcoal again, and falling off again.

Under such rigorous training, Chu He's physical abilities improved dramatically.

Boom!!!

Chu He's physical body broke through, Undying Demonic Body Refining Technique also brought his cultivation to a breakthrough, reaching the Great Grandmaster Fifth Level Realm.

"Ding! Congratulations, host! Disciple Chu He has broken through to the Great Grandmaster Fifth Level Realm. The host has received ten times the feedback, and his cultivation has improved..."

At this moment, Lin Ye's internal Core Qi had increased somewhat, and his realm had become more stable, but it was still not enough to break through to the Golden Core Second Level Realm. His physical attributes had also been improved in return, and his physical body was being tempered by the Golden Core Lightning Tribulation. Even without deliberate effort, his physical strength was still increasing.

Another half hour passed, and the fourth Lightning Tribulation was about to pass. He once again used the Heavenly Demon Lightning Sealing Pearl to seal the fourth Lightning Tribulation.

As the fifth Lightning Tribulation descended, Chu He hesitated about whether to continue tempering his body, but then Lin Ye's voice rang out.

"Chu He, you shouldn't touch the fifth Lightning Tribulation. Even the dissipated power of the Lightning Tribulation is too much for you to withstand."

"Yes, Master."

Chu He stepped down.

Afterwards, Lin Ye's disciples watched from afar as he underwent the Golden Core Lightning Tribulation.

"Seventh Junior Sister, how many times will Master have to undergo the Golden Core Lightning Tribulation?"

Ye Chen looked at Nalan Xi, who knew the most about the Golden Core Lightning Tribulation, and the others also looked over, very curious about the Golden Core Lightning Tribulation.

Nalan Xi explained, "The number of Golden Core Lightning Tribulation is related to the quality of the Golden Core. If it's only First-Transformation Golden Core, then passing one Lightning Tribulation is enough to become a true Golden Core True Person. If it's Second-Transformation Golden Core, then it requires two Lightning Tribulation, Third-Transformation Golden Core Lightning Tribulation requires three. First-stage to Third-Transformation Golden Core are called Lower Third-Transformation Golden Core, fourth-stage to sixth-stage Sixth-Transformation Golden Core are Middle Third-Transformation Golden Core, and seventh-stage to ninth-stage Golden Cores are Upper Three-Transmutation Golden Cores. Upper Three-Transmutation Golden Core are extremely difficult to cultivate. Even with top-tier special physiques, top-tier cultivation Cultivation Method, and abundant resources, it's still difficult for even the Seventy-Two Orthodox Sects to cultivate Upper Three-Transmutation Golden Core. As far as I know, within the Eastern Domain Imperial Dynasty, it's considered good to produce one Upper Three-Transmutation Golden Core every ten years, and almost all of them are Seventh-Transformation Golden Core. Eighth-Transformation Golden Core haven't appeared for many years."

"What about the Nine-Transmutation Golden Core?"

Yang Yang asked.

"The Nine-Transmutation Golden Core is considered the strongest Golden Core, a heaven-defying Golden Core that only exists in legends. I've never heard of it. Perhaps such a prodigy exists among the top few orthodox sects among the Seventy-Two Orthodox Sects," Nalan Xi said.

"What stage of Golden Core is Master?"

"This is already the fifth Lightning Tribulation, guaranteeing at least Fifth-Transformation Golden Core, and I reckon Master will be able to reach Seventh-Transformation Golden Core!"

"But Master is lazy and hasn't cultivated much. How can his foundation be solid?"

"Master, at the Martial Saint Realm, can easily crush Golden Core True Person. Do you dare say Master's foundation isn't solid?"

"Senior Brother, it's my fault."

While the group was discussing, Nalan Xi guessed and said, "Master should have a foundation of Sixth-Transformation Golden Core or Seventh-Transformation Golden Core, right? Eighth-Transformation Golden Core is too difficult, and as for Nine-Transmutation Golden Core, that's definitely impossible."

"Almost."

They thought so too.

Before long, the power of the fifth Lightning Tribulation was sealed away, and the sixth Lightning Tribulation descended, lasting for another half an hour. However, Lin Ye still felt no pressure and continued to withstand the power of the Lightning Tribulation with his physical body.

Unbeknownst to them, the power of the sixth Lightning Tribulation was sealed, and the seventh Lightning Tribulation descended.

This time, Lin Ye became slightly more serious and activated the Undying Demonic Body Refining Technique, but he still stubbornly endured the attack without choosing any talismans, Spirit Treasure, or formations.

It was known that Lin Ye had persisted for half an hour before using the Heavenly Demon Lightning Sealing Pearl to seal the power of the seventh Lightning Tribulation.

Boom!!!

The power of the eighth Lightning Tribulation descended.

"Eight... Eighth-Transformation Golden Core!"

Nalan Xi was shocked. This was a monstrous genius that an entire dynasty hadn't produced in many years. How terrifying was an entire dynasty, with a large number of Golden Core cultivators, numerous Golden Body Realm, and even several powerful figures at the King Conferment Realm who surpassed the Golden Body Realm.

Furthermore, the dynasty's ancestor was a powerful figure who surpassed even the King Conferment Realm.

Even with such a strong foundation, numerous terrifying inheritances, physical constitutions, and abundant resources, it is still impossible to cultivate an Eighth-Transformation Golden Core!

But Master did it, and is now enduring the power of the eighth Lightning Tribulation.

"Master is a prodigy! Eighth-Transformation Golden Core! I wonder if I'll be able to cultivate Eighth-Transformation Golden Core in the future."

"You'd be lucky to even cultivate Seventh-Transformation Golden Core, let alone Eighth-Transformation Golden Core? Dream on!"

"I suspect that Master's usual laziness is just an act. Perhaps while we're sleeping, Master is diligently cultivating himself!"

"Master is too amazing. He has cultivated Eighth-Transformation Golden Core. If word gets out, it will probably cause a stir among the Hundred Nations of the Eastern Domain."

"Actually, even if you told people, no one would believe it. This is the Chu Kingdom, a small place. How could those dynasties and empires possibly believe that an Eighth-Transformation Golden Core was born here? At most, they would just consider it a rumor."

While the disciples were discussing, Yu Yu felt immense pressure. Her senior brother was too monstrous, while she had only just broken through to the Great Grandmaster Realm. Compared to her senior brother, the gap was widening.

A while later, almost half an hour had passed. The disciples were preparing to congratulate Lin Ye on his breakthrough when they realized something was wrong: the Lightning Tribulation above had not yet dissipated.

"Don't go over there, the Lightning Tribulation clouds are still there!"

Nalan Xi immediately noticed the Lightning Tribulation above. Based on the Golden Core Lightning Tribulation she had witnessed before, the Lightning Tribulation clouds would quickly dissipate once the tribulation was complete. However, these Lightning Tribulation clouds hadn't dissipated, meaning that the Golden Core her master had condensed wasn't Eighth-Transformation Golden Core, but rather—

"Nine-Transmutation Golden Core!"

Nalan Xi and the other disciples exclaimed in surprise. They never expected that their master had condensed the legendary Nine-Transmutation Golden Core!
