There are over a billion transmigrators in Battle Through the Heavens.

The Ancient Emperor's Cave is an independent space created by the ancient emperor Tuoshe.

Although the entrance is located beneath the magma in the northwest region, it does not belong to the northwest region itself.

"Master, to enter the Ancient Emperor's Cave, we need to collect all the Tuoshe Ancient Emperor Jade."

"Without the Tuoshe Ancient Emperor Jade, the cave entrance cannot be opened."

Zhu Kun, standing beside Xiao Yan, offered a word of advice.

"Oh?"

"Without the Tuoshe Ancient Emperor Jade, this stone door cannot be opened?"

Xiao Yan looked at the stone gate with some disbelief.

However, on second thought, if the stone door could really be opened so easily, the lizardmen who have been guarding outside would probably have already made their move, so why would they have waited until now?

"Yes, even if the power is greater than that of the ancient emperor Tuoshe, if someone tries to force their way in, the ancient emperor's cave will explode, and everything inside will be destroyed."

Zhu Kun nodded and said.

"It seems I'll have to risk my life to get in."

"The power of destiny, shrouding the past and reflecting the future, the ancient emperor's jade manifests here..."

As Xiao Yan spoke, his lifespan began to burn rapidly.

Chapter 180 The Trans-Time Bond of Emperor Tuoshegu

As Xiao Yan's lifespan was burning out rapidly, the phantom of the Tuoshe Ancient Emperor Jade also appeared before him.

This is the illusory image of the ancient Emperor Tuoshe, captured by the Lesser Destiny Technique in the past.

Although the phantom of this Tuoshe Ancient Emperor Jade could not actually open the stone door of the ancient emperor's cave.

It's okay to open a small gap.

At this moment, when the light of the Tuoshe Ancient Emperor Jade shone on the stone gate.

The stone gate trembled slightly.

A crack, almost invisible to the naked eye, appeared amidst the tremors.

"Change!"

Upon seeing this, Xiao Yan transformed into a wisp of green smoke and entered the ancient emperor's cave through the crack.

After the system level was upgraded to level seven, the ever-changing functions allowed Xiao Yan to no longer be limited to simply becoming plants, trees, rocks, or various living beings.

He can transform everything, whether it be tangible or intangible.

……

"The Minor Fate Technique is indeed not a divine power that can be used lightly. In just a moment, it actually burned away tens of thousands of years of my lifespan."

After entering the ancient emperor's cave, Xiao Yan muttered to himself.

Don't be fooled by the fact that he just casually chanted a few lines and summoned a complete projection of the Tuoshe Ancient Emperor Jade.

But all of this was earned with one's life.

"Such rich Origin Qi!"

"If I cultivate here, I will be able to break through to the Dou Di realm very soon."

After marveling at the abundance of Origin Qi in the ancient emperor's cave, Xiao Yan discovered that it was simply outrageous.

Could it be that Emperor Tuoshegu was also a time traveler?

Otherwise, how could he have obtained so much source energy?

"Haha, Brother Xiao, welcome to the Ancient Emperor's Cave."

As soon as Xiao Yan stepped into this place, a loud laugh reached his ears.

Looking up, he saw an elderly figure dressed in dark robes smiling at him.

The old man had an ordinary appearance and nothing particularly remarkable about him.

However, her dazzlingly colorful hair was particularly eye-catching.

"Thoshegudi?"

Upon seeing this person for the first time, a look of surprise flashed across Xiao Yan's face.

He had never seen this person in the surveillance footage before.

“Brother Xiao, I have been waiting for you here for tens of thousands of years.”

"Now that you have arrived, my mission is complete."

"You may take these strange flames and use them!"

"Also, you can absorb this Emperor Flame of mine as well."

As Emperor Tuoshe spoke, he waved his hand, and the Strange Fire Plaza appeared behind him.

In the Strange Flame Plaza, all twenty-two strange flames, not one missing, were sealed on their corresponding stone pillars.

Including Tuoshegudi himself, there are twenty-three different flames.

"???" Xiao Yan.

At that moment, he was filled with doubt and didn't understand what was going on.

Why did it seem as if Thoshadguti had known him for a long time?

Moreover, why did they deliberately wait here? Was it just to deliver a strange fire to me?

Thinking of this, he couldn't help but listen to the inner voice of Emperor Tuoshegu.

My achievements today, my ability to dominate an era, are all thanks to Brother Xiao.

Today, let me lend him a hand!

Hearing the thoughts of Emperor Tuoshe, Xiao Yan became even more puzzled.

"I don't quite understand, this should be our first time meeting, right?"

Xiao Yan looked at Tuoshe Ancient Emperor and slowly spoke.

"This is indeed the first time for you right now."

Tuoshegudi chuckled and nodded.

"Oh?"

Xiao Yan raised an eyebrow, and then quickly figured out what was going on.

If he remembered correctly, Su Qian seemed to have a time travel system.

Could it be that after obtaining this system, I traveled back in time and met Emperor Tuoshegu?

"I am no match for you now. Even if we made any promises in the past, you don't need to care about them at all."

Why do you still do this?

Xiao Yan could roughly guess some things, but he didn't know the specific details.

“Brother Xiao is like a second parent to me. Since I have promised to help you become emperor and achieve hegemony, I will never break my promise.”

As Tuoshegudi spoke, a look of reminiscence appeared in his eyes.

However, this sense of nostalgia was quickly replaced by a resolute look in his eyes.

If it weren't for Brother Xiao passing on the Burning Technique to me and helping me devour the strange fire, how could I have reached this point today?

Everything I have was given to me by Brother Xiao, so it is only right that I give back to him when he was weak.

Xiao Yan exclaimed in surprise at Tuoshe Ancient Emperor's heartfelt words.

It turns out that the Burning Technique was a cultivation method he himself gave to Emperor Tuoshegu.

After going through many twists and turns, it eventually came back into his hands.

"Are you really willing to give up everything for me?"

Xiao Yan confirmed with Emperor Tuoshe again.

“That’s right, I have done everything Brother Xiao asked me to do.”

"In my life, I have experienced both hardship and glory, and I have even led an era. But now, the only thing I can do is help you embark on the path to God."

"However, there is one more thing I need to remind Brother Xiao of."

"The waters of the Dou Qi Continent are far deeper than you and I can imagine. Even at my peak, I couldn't figure out where the limits of this world really are."

"Brother Xiao, come on!"

"The strange fires here have all been enhanced by you, far surpassing those outside. Once you devour these strange fires, you will be qualified to explore the true mysteries of this world."

As soon as he finished speaking, Emperor Tuoshe transformed into a strange flame and merged into the Strange Flame Plaza, waiting for Xiao Yan to devour it.

"Appraisal!"

The moment Tuoshe Ancient Emperor transformed into a strange flame, Xiao Yan used the appraisal function.

Name: Tuoshegudi (His life is nearing its end.)

Race: Different Flames!

Gender: Male.

Cultivation level: Perfect Ancient Emperor.

Talented Bloodline: None! (Originally an ordinary strange fire, it later broke through its limits step by step with the help of the Burning Technique, becoming a perfect ancient emperor.)

……

"His days are numbered? The Perfect Ancient Emperor?"

Xiao Yan hadn't realized that Tuoshe Ancient Emperor was already nearing his end.

Moreover, what kind of realm is the Perfect Ancient Emperor?
