"hiss!"

Seeing Tang Xuan's calm expression, the Demon Prince was actually somewhat moved.

Although Tang Xuan used threats and inducements to coerce him, he did not abandon him after winning him over. Instead, he genuinely cared about his final battle.

This moved him deeply.

Tang Xuan clapped his hands.

"Wanwan, go outside and keep watch. No one is allowed to set up shop. Anyone who trespasses will be killed without exception!"

"Yes, Master!"

Wanwan walked out of the house.

Tang Xuan shouted at the Demon Slayer Prince, "Sit down. I'll help you improve your cultivation first. Don't be too surprised no matter how you feel later!"

"Uh... okay!"

The Demon Prince agreed with a skeptical tone.

How could one's cultivation level possibly improve so quickly?

A martial artist's skill is honed little by little over time.

Using secret methods to improve one's abilities is tantamount to overdrawing one's life force, which is a grave taboo.

However, bound by the blood pact, Prince Yao Tu had no choice but to comply.

Tang Xuan pointed a finger at his forehead.

"System! Increase his cultivation level tenfold!"

Prince Yao Tu's body swayed violently.

He suddenly felt as if the demonic energy swirling within him had been ignited.

With a loud bang, an extremely violent force surged out from within his body.

"ah……"

The Demon Prince was startled, thinking that Tang Xuan had forcibly infused his spiritual energy into him.

But upon closer inspection, something felt off.

The raging demonic energy posed no obstacle to him; it was as if he had cultivated it himself.

His body was like a well.

Tang Xuan pulled off the well cover, and a continuous stream of water gushed out.

"Awooooo!"

The Demon Prince was enveloped by an extremely powerful spiritual energy.

His cultivation level began to surge at a visible rate.

In the blink of an eye, he had already soared to the peak of the Gathering Peak Realm.

The next moment!

The demon prince felt excruciating pain in his internal organs.

My heart, liver, spleen, lungs, and kidneys feel as if they've been stabbed with a knife.

The spiritual energy of heaven and earth poured into it wildly.

"The Fifth Elemental Realm!"

Prince Yao Tu suddenly opened his eyes, filled with boundless joy.

Tang Xuan did not lie to him.

It can really help you improve your cultivation level.

Even after breaking through to the Fifth Elemental Realm, it's not over yet.

His cultivation level continued to surge.

Entry into the Five Elements Realm!

Minor Success in the Fifth Elemental Realm!

Great achievement in the Five Yuan Realm!

final!

Prince Yao Tu's cultivation level has reached the peak of the Five Elements Realm.

This exceeded Tang Xuan's expectations.

"Oh, this guy... he's got some talent!"
