Chapter 254: Heavenly Dao Oath, Nangong Wan’s Shock

"So, Fellow Daoist Wu, you intend to take this entire golden thunder tree forest with you?"

Looking at the golden thunder tree forest before her that had not yet fully matured, Nangong Wan looked at Wu Li and asked curiously.

Wu Li pondered for a moment, and after some hesitation, his expression firmed up as he looked at Nangong Wan and spoke.

"Fellow Daoist Nangong, I need you to swear a Heavenly Dao Oath. You must not reveal what happens next. Otherwise, today's events can be known by two people, or they can be known by one."

Hearing this, Nangong Wan's breathing couldn't help but quicken. She could naturally tell that Wu Li was treating her as one of his own; otherwise, he wouldn't say such things to her.

As for the Heavenly Dao Oath? She hadn't planned on talking about what happened here anyway, so naturally, it wouldn't have any impact.

Thinking of this, Nangong Wan swore the Heavenly Dao Oath without hesitation. As a faint, rumbling sound came from the Void Realm, Wu Li's expression appeared much more at ease.

The Heavenly Dao Oath was a procedure established by the Heavenly Dao. As long as the Heavenly Dao acknowledged it, unless one possessed strength comparable to the Heavenly Dao, death was inevitable if broken.

After Nangong Wan swore the Heavenly Dao Oath, Wu Li finally made his move and took out the Palm Saint Bottle directly.

The moment Wu Li took out the Palm Saint Bottle, Nangong Wan's breathing couldn't help but quicken. This was her first time seeing a five-colored level item. She had been fortunate enough to see an immortal emperor artifact before, but that only had golden Luck.

But now it was actually five-colored. Could the Palm Saint Bottle in Wu Li's hand be a treasure above the level of an immortal emperor artifact?

At this moment, Wu Li also spoke.

"This is the Palm Saint Bottle. It has the effect of catalyzing the growth of Heaven And Earth Treasure and accelerating the speed of Cultivate. Coupled with the help of my own Space-Time Divine Body, I can force the golden thunder tree to grow to a million years of age within one year. By then, it will be seventh-grade gold lightning wood!"

Following Wu Li's words, Nangong Wan's breathing couldn't help but quicken again. She had not expected that a person with five-colored Luck would be so terrifying, actually possessing a Space-Time Divine Body.

One had to know that this was a divine body. Even if the Five Great Holy Lands knew about it, they would definitely fight over Wu Li, just to recruit him into their forces.

But she had never heard of this person, Wu Li, in the Upper Realm. It was evident that Wu Li was definitely a very low-key person; otherwise, he wouldn't be unknown.

"Fellow Daoist Nangong, please leave first and act as my Protector."

Hearing Wu Li's words, Nangong Wan did not hesitate, nodded in agreement, and left.

After Nangong Wan left, Wu Li took a deep breath, and his expression became resolute.

The next second, Wu Li reached out his hand, and countless Formation Stone flew out from his Storage Ring, heading towards the golden thunder tree forest in front of him.

He needed to set up a time acceleration Formation, using his own Space-Time Divine Body as the formation base. After all, there was nothing in the Upper Realm that could serve the purpose of setting up a time acceleration Formation.

Moreover, Wu Li had checked, and in the Upper Realm, Formations regarding time acceleration were extremely rare, and they were basically eighth or even ninth-grade immortal Formations, which were not things Wu Li could set up right now.

Therefore, after some simplification, he arrived at the time acceleration Formation that Wu Li could set up now. Even so, with the help of the Space-Time Divine Body and the Palm Saint Bottle, it still had a terrifying time acceleration effect of one million times.

Soon, as Wu Li controlled it with his Divine Thought, the area around the ten thousand golden thunder trees in front of him was shrouded by the time acceleration Formation. Wu Li did not hesitate, flew to the center of the golden thunder tree forest, and took out the Palm Saint Bottle again.

As Wu Li opened the mouth of the Palm Saint Bottle, the next second, drops of time nectar flew out from the Palm Saint Bottle. After the golden thunder trees below absorbed the time nectar, they began to grow at a speed visible to the naked eye.

"Although it is fast, this is not enough!"

Wu Li looked at this scene with a solemn expression. The next second, he used himself as the formation base to begin connecting the surrounding Formation Stone. He saw countless cyan lights flying from around the golden thunder tree forest towards Wu Li, and soon they merged into Wu Li's body.

As the cyan light merged into Wu Li's body, Wu Li closed his eyes.

"Whoosh!"

Hearing a sound from Wu Li's body, everything around him began to accelerate slowly, and it soon reached a degree where one could only see afterimages.

As for the gold lightning wood below, it could even grow several meters high in a single day.

One must know that a golden thunder tree of half a meter is fifth-grade, ten thousand meters is sixth-grade, one million meters is seventh-grade, one hundred million meters is eighth-grade, and one hundred million meters is ninth-grade.

It was just that because of the environment of heaven and earth, it seemed that golden thunder trees in the Upper Realm could only grow to the seventh grade; anything above the seventh grade was completely impossible.

Outside the Formation, after seeing this scene inside, Nangong Wan's expression also appeared extremely shocked. Although she felt very tempted looking at the wildly growing golden thunder trees before her, she ultimately did not do anything.

Perhaps seventh-grade gold lightning wood was very precious, but what was more precious than gold lightning wood was Wu Li. If she could make friends with Wu Li, mere seventh-grade gold lightning wood was nothing.

As time passed second by second, the golden thunder trees inside the Formation grew to the sixth grade in just one month and were still advancing towards the seventh grade.

Finally, in the last ten days before the Azure Lightning Secret Realm was about to close, a series of rumbling sounds were heard from the sky of the Secret Realm. Nangong Wan couldn't help but look up, only to see that the sky above the Formation was already shrouded by pitch-black Lightning Tribulation.

"Is this the Lightning Tribulation for the golden thunder tree to advance to the seventh grade?"

Nangong Wan thought with a heavy heart, but she had no way to intervene. Everything could only depend on whether the golden thunder trees could successfully complete their Undergoing Tribulation. If she interfered rashly, it would only provoke the frenzy of the Lightning Tribulation, leading to death and dissipation.

Inside the Formation, Wu Li also opened his eyes and looked at the Lightning Tribulation in the sky. With a wave of his hand, he dispelled the time acceleration Formation, and his face appeared somewhat pale.

After all, letting the Formation absorb his power for a year, it would be strange if he wasn't weak.

"Next, it can only depend on whether the golden thunder trees are hard-working enough."

Looking at the golden thunder trees, Wu Li thought to himself.

He could perceive that the golden thunder trees before him had all reached an age of one million years. If they could all successfully advance, then he would be able to obtain tens of thousands of Golden Thunder Flying Sword. By then, combined into the Golden Thunder Flying Sword Formation, even if an Immortal Venerable arrived, he could contend against it single-handedly!
