Immortal cultivation starts with copying.

Chapter 820 A Difficult Tribulation

Chen Yunhao's idea was ingenious. Using heavenly lightning to deal with heavenly lightning was not just about drawing them aside; that's the difference between being proactive and reactive.

He remembered that when Ling Qingfeng was undergoing his tribulation, even the method of traction couldn't sustain him for long.

However, if he used this method, a single thunder hammer could withstand at least six celestial thunderbolts, making it extremely useful.

He left quite a few of these treasures in the Taiyi Sect, because his master Lin Changfeng and his two senior brothers were all orthodox thunder magic practitioners, so using this thunder hammer was a piece of cake for them.

Chen Yunhao was using it for the first time, which set an example for others.

At least Lin Changfeng and his two senior brothers' expressions kept changing as they watched. This was truly a treasure tailor-made for them!

Just as Chen Yunhao had predicted, the Thunder Hammer could indeed withstand the six celestial lightning strikes for him.

When the seventh bolt of celestial lightning struck, and he tried to continue absorbing the heavenly lightning, cracks appeared on the lightning hammer, indicating that it was no longer usable.

Of course, this is only the performance of the first Thunder Hammer. As the power of the heavenly thunder gradually increases, the amount of heavenly thunder that the Thunder Hammer can contain and resist will gradually decrease. This is an indisputable fact.

When the seventieth bolt of lightning strikes, the lightning hammer can only store one bolt of lightning at a time; any more and it will explode.

Of course, it can only withstand one bolt of lightning, meaning that a single lightning hammer can only withstand two bolts of lightning.

By this point, Chen Yunhao was quite satisfied. This was the Nine-Nine Heavenly Thunder, and he only needed to endure eleven more heavenly thunders to end it.

After the seventy-fifth bolt of heavenly lightning struck, his top-grade thunder hammer spiritual treasure was about to become obsolete.

The power of the heavenly lightning was so great that even this top-grade spiritual treasure couldn't withstand a single strike.

So far, only six heavenly lightning bolts remain. Although they are the most powerful of the six heavenly lightning bolts, Chen Yunhao remains very calm because he still has a backup plan.

Of course, his magical abilities alone were not enough to withstand the most powerful Six Paths of Immortal Lightning. He also possessed a most powerful treasure, the semi-immortal artifact, the Heaven-Asking Sword.

Semi-immortal artifacts are treasures that cultivators in the spirit realm can refine, which are infinitely close to immortal artifacts. They are the most top-tier existences in this realm and Chen Yunhao's greatest source of confidence.

With a flick of his wrist, Chen Yunhao produced a broken flying sword.

Just as the seventy-sixth bolt of heavenly lightning was about to strike, Chen Yunhao, holding his flying sword, gently slashed it towards the sky.

A faint sword light flashed by, just as the heavenly lightning struck.

The sword light collided with the heavenly lightning, but there was no violent explosion; instead, it was completely silent.

A beam of sword light cleaved the lightning in two, causing it to dissipate into the air.

“Semi-Immortal Weapon…!”

Several low exclamations came from afar. Zhao Yuyang, Lin Changfeng, and even the Great Demon Tiger Roar were all people with sharp eyes, so they naturally recognized what the treasure in Chen Yunhao's hand was at a glance.

Although it is a semi-divine artifact, it is still incomparable to any top-grade spiritual treasure; they are not even in the same league.

Moreover, only cultivators who have reached the late stage of the Tribulation Transcending Realm, or even the Great Perfection Realm, can wield a semi-immortal artifact and unleash more than 50% of its power.

But Chen Yunhao is different from ordinary cultivators; he can fully unleash the power of a semi-immortal artifact.

The key is that he has immortal energy in his body. Only by using immortal energy as a driving force can a semi-immortal artifact truly unleash its power.

Because Chen Yunhao had reached the Great Perfection of Tribulation Transcending, the immortal energy he had cultivated within his body was no longer useful. It gradually began to replace the spiritual power within his body, making his body closer to a half-immortal body.

The advantage of doing this is that after he transcends his tribulation and ascends to the Immortal Realm, becoming an Earth Immortal, his strength will be 30% stronger than that of a newly promoted Earth Immortal.

This is the benefit of having the first move; a solid foundation leads to a higher starting point, which is extremely beneficial for his future cultivation and development.

Another point is that Chen Yunhao only has this one semi-divine artifact; there is no second one.

It wasn't that Chen Yunhao didn't want to make more copies; he also wanted to leave half of one for his relatives, friends, and disciples in the sect.

However, the ancient mirror cannot currently replicate semi-divine artifacts, let alone divine artifacts.

In Chen Yunhao's mind, the ancient mirror had always been omnipotent. It was only when the ancient mirror told him that it could not replicate a semi-immortal artifact that Chen Yunhao secretly became a little anxious.

That's why he later cultivated relentlessly, never leaving the sect for nearly a thousand years.

He wants to go to the Immortal Realm to restore the Ancient Mirror's power; this is his wish and goal.

With a single sword strike extinguishing the heavenly lightning, Chen Yunhao's confidence soared. He had only used 60% of his strength in that strike, yet it still had considerable power!

The heavens seemed to be enraged; the seventy-seventh bolt of heavenly lightning, after brewing for a long time, finally struck with earth-shattering force.

This bolt of lightning was 30 to 40% more powerful than the previous one, which was quite unusual.

Chen Yunhao had no time to think. He let out a low shout, leaped up, and slashed out with his sword again.

This sword strike carried eighty percent of his strength, and the collision was silent. The heavenly lightning dissipated, but Chen Yunhao also fell heavily to the ground.

His right hand, which was holding the sword, trembled slightly, and a look of surprise flashed in his eyes.

He had watched Ling Qingfeng undergo his tribulation and remembered that the tribulation lightning was not this powerful under the same heavenly lightning. Could it be because of the semi-immortal artifact in his hand, or the immortal energy in his body that caused the tribulation lightning to change?

All of this is possible, but now is not the time to think about it. He focused on restoring the spiritual energy he had lost.

After taking three or four level-eight spirit pills in a row, the spiritual power lost in his body was finally slowly replenished.

Fortunately, the last few bolts of heavenly lightning had been brewing for a relatively long time, giving Chen Yunhao ample time to prepare.

The seventy-eighth heavenly lightning strike was met with Chen Yunhao using ninety percent of his spiritual power, yet his arm still trembled and went numb.

As expected, the power of the heavenly lightning increased with each subsequent strike. Although it didn't increase exponentially, each strike was 30-40% stronger than the last, enough to destroy most of the cultivators undergoing tribulation.

Chen Yunhao shook his arms, swallowed a few more elixirs, and slowly regulated his breathing.

The preparation time for the seventy-ninth heavenly lightning bolt was longer than usual, unlike anything Chen Yunhao had ever seen.

He clearly remembered that when Ling Qingfeng was undergoing his tribulation, the last few bolts of heavenly lightning didn't take this long.

The longer it drags on, the greater the power of the heavenly lightning will be, and the power of the heavenly lightning is entirely adjusted according to the strength of the person undergoing the tribulation.

Therefore, this indirectly confirms Chen Yunhao's strength, which is very clear to the people watching from afar, including the Great Demon Tiger Roar.

Only at this moment could they truly feel Chen Yunhao's strength.

None of them would have been able to survive this level of celestial tribulation.
