But over time, there will be some improvement, though the extent of this improvement will not be very significant.

As for the time spent.

Shen Changqing estimated that it would take at least a hundred years.

Therefore,

the power permeating Thunder Prison Valley was not his real objective.

Suddenly,

a bolt of thunder struck down.

Nearby, a mountain suddenly shattered into fragments, with the surging energy flashing by in an instant, leaving a dense thunderous aura in the aftermath.

"This place has borne the pounding of thunder for years on end, and both the land and the mountains here are as hard as Dao Arms."

He looked towards the mountain stone that had crumbled.

The power of that bolt of thunder was already not weaker than the post-stage of the Divine Realm.

Even so,

it wasn’t able to destroy the mountain, leaving only insignificant marks.

One should know,

in the outside world,

a post-stage Divine Realm strike could easily destroy not just a mountain, but even a towering peak of ten thousand feet, leaving no traces behind.

By comparison, one can understand just how hard the mountains in Thunder Prison Valley are.

He looked up towards the firmament, where thunderclouds gathered densely.

Just as Thunder Prison Valley seemed endless, so too did the thunderclouds.

However, the energy within them gave a sense of vastness like an abyss.

"To temper the body in Thunder Prison Valley, it can’t just rely on natural pressure. The real things that can temper the body should be only two kinds: one is the Thunder Essence contained in the Thunder Spirit, and the other is the falling thunder!"

Shen Changqing pondered.

Thunder represents destruction, but also rebirth, and the power contained within is vast.

If one can withstand the tempering of thunder, they will naturally absorb its power and gain benefits.

But if one cannot withstand it, they will perish in the thunder. 𝑓𝓇𝘦ℯ𝘸𝘦𝑏𝓃𝑜𝘷ℯ𝑙.𝑐𝑜𝓂

As for absorbing the power of thunder,

he was quite experienced.

When he was in the Human Clan Realm, he had once used the power of thunder for cultivation, and he understood the ways of it very well.

However—

The natural thunder in the outer world is generally not very strong and doesn’t provide much help to him.

Unless special means are used to summon powerful thunder, it might have some effect.

But the thunder of Thunder Prison Valley is different.

This thunder formed from the remnant body of a Divine Lord is naturally extraordinary, and if he can absorb and refine this thunder, it would be much better.

"But there’s a problem, which is that the falling of the thunder seems to follow no pattern, making it difficult to accurately locate its point of impact."

Shen Changqing’s brow slightly furrowed.

Since entering Thunder Prison Valley, numerous bolts of thunder had fallen, yet he hadn’t discovered any pattern among them.

"Moreover, since Thunder Prison Valley is formed from the remnant body of a Divine Lord, there might be some Divine Lord Blood left. If there truly is, even obtaining a single drop would be immensely beneficial!"

Shen Changqing thought of other things.

He had already witnessed the power of the Divine Lord Blood.

Obtaining another drop of Divine Lord Blood would undoubtedly be greatly advantageous.

However, Thunder Prison Valley has existed for millions of years, and if there is Divine Lord Blood, it is likely to have been taken by the Zhongshan Clan or dissipated into dust over time.

The possibility of truly finding it is very slim.

Immediately,

Shen Changqing refrained from speculating further and only raised his head to observe the thunderclouds for any signs of change.

Suddenly,

the calm thunderclouds showed slight agitation.

He stepped out, appearing directly atop a mountain.

Almost simultaneously,

boom!!

A massive bolt of thunder struck down from the clouds.

Shen Changqing did not resist, allowing the thunder to envelop him.

In an instant, the violent power slammed into his flesh, causing it to tremble vigorously, with his flawless skin showing slight cracks that soon vanished.

However, at this moment, the power of the thunder had surged into his flesh through the skin.

He directly mobilized his vitality and completely refined the thunder power that had invaded.

Half an hour later,

Shen Changqing exhaled, "The power of that bolt of thunder was quite good, comparable to the energy contained in a seventh or eighth rank Divine Pill. If I could withstand dozens or hundreds of them, I could create a secret treasure."

Don’t be fooled by the fact that a single bolt of thunder is equivalent to a seventh or eighth rank Divine Pill as if it were very powerful.

But in fact,

at his level, each creation of a secret treasure requires a huge amount of energy.

Even if it were Heaven and Earth Divine Pills, without sufficient quantity it’s hard to make an impact.

As he progressed further,

Shen Changqing increasingly felt the difficulty of creating secret treasures.

But with insufficient Slaughter Value, he had no choice but to open up the secret treasures step by step in this way.

He had a premonition.

Once all the secret treasures were opened, he would undergo a shocking transformation.

This transformation,

would not be as simple as opening a Cave Heaven.

But what kind of transformation it would be, Shen Changqing did not yet know.

At this moment,

the thunderclouds moved again.

Shen Changqing then once again arrived at the corresponding location, and as expected, thunder fell.

After absorbing its power, he had basically understood the pattern of the thunder.

"Every time thunder is about to fall, the thunderclouds will have some movement, and just now this bolt seemed stronger than the previous ones. It seems that the deeper into Thunder Prison Valley one goes, the stronger the thunder becomes.

No... It’s not just the thunder’s power, even the space pressure is stronger than before."

Shen Changqing’s expression changed.

If it truly is so, then venturing deeper into Thunder Prison Valley would undoubtedly be highly beneficial.
