These residual true essence powers are like ticking time bombs, hidden within the Sea of Clouds, ready to cause catastrophic consequences at any moment.

However, over time, these hidden dangers can be gradually eliminated through one's own cultivation.

As long as Chu Nan perseveres in cultivation, there will come a day when he can resolve these lurking crises.

But sadly, the time left for Chu Nan is too short, he doesn't even have time to eliminate these hidden dangers.

Thus, in the midst of an intense battle, these dangers erupted unexpectedly, which greatly affected his combat ability negatively.

The void suddenly cracked open, and Chu Nan's body was relentlessly torn by the violent power of space, wobbling like a candle in the wind, as if it could extinguish at any moment.

Meanwhile, Ji Shen Technique's attacks became increasingly fierce and terrifying.

His pair of sharp claws were as sharp as a sacred-level spirit martial weapon, easily able to tear through a martial artist's tough flesh.

Faced with such ferocious attacks, Chu Nan could only fall back step by step, barely holding on.

"Chu Nan, oh Chu Nan, you've already shown signs of defeat, there's no chance for victory left!"

Ji Shen Technique laughed triumphantly, delivering another punch that violently repelled Chu Nan, causing him to tremble violently, making it difficult to move an inch.

Immediately after, he ruthlessly struck again, his hand as sharp as a dragon's claw directly aiming for Chu Nan's heart, clearly intending to kill him in one fell swoop.

Seeing Chu Nan in extreme danger, no one could have expected that in this moment, he suddenly swung a sword.

This sword qi was as fast as lightning, precisely landing on Ji Shen Technique's hand, slicing through the flesh, muscles, and bones, almost cutting off his entire hand.

"You actually still have strength left!" Ji Shen Technique said in shock, holding his nearly severed hand.

His eyes were filled with disbelief. For him, the injury was nothing; what truly surprised him was Chu Nan's ability to unleash such fearsome strength.

Facing Ji Shen Technique's confusion, Chu Nan simply let out a cold laugh and then said indifferently, "I still have plenty of strength left, do you want to try it all?"

His voice was calm and confident, as if he didn't consider Ji Shen Technique a threat at all.

At this moment, Chu Nan appeared breezy and unperturbed, showing no signs of weakness. This scene made Ji Shen Technique doubt if Chu Nan's earlier display of weakness was merely a facade.

Thinking of this, Ji Shen Technique no longer dared to underestimate Chu Nan in the slightest.

It was simply because Chu Nan was too terrifying; every time he thought Chu Nan had reached his limit, Chu Nan would unleash incredibly terrifying strength again, bringing endless shock and dread.

After successfully repelling Ji Shen Technique, Chu Nan let out a long breath.

At this moment, in his Dantian, a source pill was dissolving rapidly.

In fact, he was already unable to fight back against Ji Shen Technique, but it was because he timely refined this source pill that he gained the strength to counterattack.

These source pills were taken from deceased martial artists of the Return to One realm from the Huo family.

By using the energy from refining the source pill, Chu Nan accelerated the fusion of the Yin Yang Cloud Sea, temporarily suppressing the hidden dangers within his body and gaining greater strength.

However, this method was merely a temporary solution, akin to drinking poison to quench one's thirst.

Although it could grant Chu Nan powerful combat power in the short term, it also caused more foreign true essence power to merge into his body, making his hidden dangers more severe.

Chu Nan understood the serious consequences of such actions, knowing that he would eventually reach the limit of absorbing the source pills.

When that time came, even absorbing more source pills might have no effect. In the best case, it could lead to the collapse of the Yin Yang Cloud Sea, and in the worst case, it could result in his death!

He chose to do so because he had no other choice.

Ji Shen Technique wasn't wrong; the side of the strong race and the royal family had numerous Return to One realm strongmen.

In contrast, Chu Nan's side only had three people. Although the three possessed earth-shaking cultivation, they were ultimately outmatched by numbers!

As time went on, if they continued to hold their ground, Chu Nan's side was destined to lose, possibly even without a chance to fight back.

The speed of his rise was indeed astonishing, but Chu Nan's foundation was ultimately slightly inferior compared to the Ji family of the royal family, which has commanded the Celestial Crossing Realm for thousands of years, inheriting since the realms were undivided.

Over thousands of years, not only the royal family itself but numerous loose cultivators had joined to bolster its prestige.

Once the power suppression dissipated, those who benefited the most were not Chu Nan but the royal family.

With the suppression gone, the Ji family could finally unleash more means.

Whether in terms of treasures or cultivation, the gap between Chu Nan and the Ji family was enormous.

Without the assistance of True Person Tianxuan, Chu Nan would not even qualify to confront Ji Shen Technique.

He might have been captured by Ji Qinghuo as soon as he appeared.

As the fierce battle continued, Chu Nan's hidden dangers quickly erupted again, giving Ji Shen Technique the opportunity to suppress Chu Nan with a fierce advantage.

Although Chu Nan devoured another source pill, he could barely manage a draw with Ji Shen Technique this time.

"There is indeed a limit to source pill consumption. If I want to turn the tables, I must break through to the Return to One realm!"

Chu Nan appeared outwardly calm, but his heart was burning with anxiety.

However, amidst the intense battle, he maintained an extraordinary calmness, making it difficult for Ji Shen Technique to gain any advantage over him.

Meanwhile, the situation on the other two battlefields was drastically different.

As the battle continued, Lu Daochang's true essence power gradually diminished. Although he continuously devoured spirit stones to replenish it, this method was only a temporary solution and could not be maintained for long.

After breaking through the Return to One realm, martial artists can condense a source pill, which is key to producing true essence power.

While spirit stones can quickly replenish spiritual power, replenishing true essence power is exceedingly slow.

After entering the Return to One realm, the energy in spirit stones can no longer meet the daily needs.

Despite Lu Daochang's aura still being incredibly formidable, he had actually reached the point of exhaustion, with nothing left to give.

The martial artists of the strong race and the Sea of Suffering employed a clever strategy; they only entangled with Lu Daochang without frontal confrontation.

Whenever Lu Daochang pursued them, they scattered and fled; when he paused, they regrouped to launch attacks.

This tactic left Lu Daochang running ragged, with no time to catch his breath.

They were waiting for the moment when Lu Daochang exhausted his true essence power, at which point they would reveal their ferocious fangs, leaving him completely defenseless.
