Lin Chen and the other two entered the Heavenly Tower, but strangely, after entering, Lin Chen found himself surrounded by mist, and Yu Feifei and Yao Hui were nowhere to be seen.

Through the mist, Lin Chen was instantly stunned by the scene before him.

This was an ancient battleground, the war evidently just ended, as the smoke hadn't dissipated.

The ground was covered with bodies, and the rivers had turned into blood.

Looking at the war flag on the ground, Lin Chen's gaze focused.

"This is the Battle of Zhuolu!"

Walking through the mountains of corpses and seas of blood, Lin Chen couldn't help but be awed by the grandeur of the battle before him.

There are many legends about this battle, and today Lin Chen finally witnessed the cruelty of this war himself.

Why was he entering this ancient battlefield?

Filled with questions, Lin Chen continued forward and suddenly looked down at his feet, his gaze holding steady.

Outside the Heavenly Tower, more people gathered, a solemn expression on every face.

"Shishi, sister, what will one encounter inside the Heavenly Tower?" An Ningning asked curiously.

Tian Shishi was one of those who entered the Heavenly Tower in the last term at the Earth Hall, but she hadn't comprehended the Qihuang Inner Classic.

Upon hearing An Ningning's question, Tian Shishi couldn't help but smile bitterly.

"It's practically hell!" Her face showed a pained expression, evidently the memory was one she didn't want to recall.

Seeing An Ningning's puzzled look, Tian Shishi said, "I didn't go deep in there, I lasted for fourteen days before coming out, it's truly terrifying."

Tian Shishi's eyes revealed the scene from back then, the endless stream of skeletal soldiers, it was practically a living hell.

At this moment, Lin Chen's foot just stepped onto the ground and was immediately grabbed by a bloody hand.

A Purple Flame Golden Fire rose beneath Lin Chen, incinerating the bloody skeleton to ashes.

One step, two steps...

Lin Chen trudged forward, almost every step was entangled by countless skeletal soldiers.

"Damn it, how could anyone possibly reach the end!"

Lin Chen's gaze fell atop his head, on a glowing ancient tree.

Only by reaching the Qihuang Tree could he have a chance to comprehend the formidable Qihuang Inner Classic.

"Red Lotus Fury!"

A fiery lotus exploded among the ghostly warriors, finally opening a path ahead, but as Lin Chen charged forward only four or five meters, the path was soon filled again with ghostly shadows.

Time ticked by, a week had passed since entering the Heavenly Tower, Lin Chen had only traversed half of the eighty-one levels, and he found that the higher he went, the stronger the apparitions became.

Bang!

Lin Chen slammed his palm, scattering the apparition before him, struggling step by step upward.

Now Lin Chen finally understood why the Qihuang Inner Classic was so difficult to comprehend; along the way, he couldn't count how many ghostly warriors he had slain, testing not only physical stamina but also mental fortitude.

In this endless slaughter, any slight deviation in mindset would lead to losing oneself, getting lost inside the Heavenly Tower, devoured by the infinite apparitions.

Outside the Heavenly Tower, suddenly the stone door opened, and a figure staggered out, collapsing onto the ground.

"Yao Hui!"

At this, Zhou Fei's face changed, leaping quickly to Yao Hui's side.

At this moment, Yao Hui's face was ashen, with an endless terror reflected in his eyes.

The peaceful mountain suddenly erupted in chatter.

"It seems Yao Hui has failed," Tian Shishi shook her head.

Tian Shishi had previously stayed inside for fourteen days, while Yao Hui lasted a total of twenty days, yet still failed.

"What's inside to make someone as powerful as Yao Hui end up like this?" Discussions arose as everyone saw Yao Hui carried back unconscious by Zhou Fei.

"It seems Yao Hui couldn't persevere, I wonder how long Feifei and Lin Chen can hold on," Yu Yuntian took a deep breath, eyes on the Heavenly Tower's center.

At this moment the center of the tower still had two lights shining, proving Lin Chen and Yu Feifei were still advancing towards the tower's peak.

A month passed swiftly, during this month Yu Yuntian, Elder Wei, and Wang Chen didn't leave the tower's entrance.

Their expressions grew increasingly solemn, and now the two lights were nearing the tower's tip.

But the closer it got, the more anxious the few became, because this distance was the most dangerous, problems could arise anytime.

Just then, a lamp at the top of the tower went out again.

Yu Yuntian and the others couldn't help but silently sigh, indeed the last challenge wasn't overcome.

"But who exactly failed?"

All eyes were fixed on the stone door.

Finally, the stone door opened, and a graceful figure slowly walked out.

Her expression was very calm, though her face was pale, she wasn't as miserable as Yao Hui.

Yu Yuntian jumped across, sympathetically asking, "Feifei, are you alright!"

Yu Feifei shook her head, "Dad, I'm sorry, I couldn't pass the last challenge."

Yu Yuntian smiled, "It's alright, getting this far is already impressive."

With Yu Feifei's exit, now only one light was shining on the Heavenly Tower, and that was Lin Chen.

Yu Feifei raised her head, looking at the small lamp like a dust star in the night sky, taking a deep breath, "Lin Chen, you must hold on!"

Inside the Heavenly Tower, Lin Chen was covered in blood, his steps unsteady, even somewhat stumbling.

And before him, apparitions kept emerging.

Lin Chen had reached the seventy-ninth level, only two levels from the eighty-first.

Lin Chen took a deep breath, stepping onto the eightieth level.

This is!

Just arriving at the eightieth level, before him was a narrow corridor, flanked by seventy-two ghostly beings, towering like iron giants.

These apparitions were entirely different from the earlier ones, all clad in armor, some even had beast-shaped iron armor, very imposing.

As Lin Chen stepped within, the eyes of the seventy-two beast-shaped iron-armored warriors suddenly lit up, an overwhelming aura instantly enveloped the entire tower.

"Damn it!"

Feeling this aura, Lin Chen's face immediately changed.

These seventy-two beast-like iron-armored warriors each possessed peak True God Realm strength, defeating them seemed impossible.

Lin Chen halted, eyes flickering, if he charged ahead, he would undoubtedly be torn to shreds, but stopping here, although such an achievement was somethiing to be proud of, the aspiration to comprehend the Qihuang Inner Classic would remain unreachable.

Thinking of Zhao Xiaowen lying in bed, a fierce determination appeared on Lin Chen's face.

He took a deep breath and strode towards the seventy-two beast warriors.

However, as Lin Chen stepped into the range of their attack, the seventy-two warriors suddenly moved.

Charging like lightning, they rushed toward Lin Chen.

At that moment, Lin Chen felt himself locked by their gaze, unable to move.

"Damn it!"

Is he going to be torn apart just like this, ending in failure?

"My brothers? Are you all alright?"

But at that moment, a voice deep within Lin Chen's soul suddenly resonated.
