Chapter 2106: External Circulation of Heaven and Earth

“I thought you were going to throw me out,” Lu Yun said haltingly as he rubbed the back of his neck.

“Throw you out?” Yuan Yi huffed at him. “Did I spend all that time and effort saving you from the pit just to throw you out of the city? Don’t worry, I’ve memorized your method of heaven and earth and will train Wang Shu well.”

“Okay!” Lu Yun nodded. Truth be told, one’s strength wouldn’t increase by much even if one cultivated for a lifetime in the city. Dangers in the wilderness were also an enormous function of luck.

“But before I go, I’m going to repair the city’s formation,” he mentioned again.

“Repair the city’s formation?” Yuan Yi frowned. She would’ve repaired it long ago if that were possible. With no more origin stones, it was a futile effort to repair the formation.

Jingzhou City’s formation teetered on the edge of collapse. Although there were still a few pieces of origin stones within it, no one knew when they would be fully consumed.

The moment the formation collapsed would be the moment the city fell.

“The formation of heaven and earth,” Lu Yun chuckled. “My cultivation method stems from one formation—the formation of heaven and earth. I can modify the city’s formation into that and have it circulate as a self-contained heaven and earth. That will provide endless origin stones and create its own cycle of reincarnation.”

Lu Yun paused when he said the word “reincarnation”. The heart of a circulating heaven and earth was reincarnation. His method of heaven and earth was actually the process of cultivating reincarnation. Instead of cultivating the strength of reincarnation, the method approached it from the angle of manifesting reincarnation through the operation of heaven and earth.

Flames were the external manifestation of reincarnation. Heaven and earth.. were the manifestation of reincarnation.

He nodded without a flicker of change in expression.

“It looks like the solution to this part of reality is reincarnation.” Lu Yun nodded slowly. He would have to save this world first if he wanted to dismantle the barrier of nothing and end the great devastation.

He couldn’t do it alone—he really couldn’t. But who could help him?

He’d have to help himself first. Hope was possible only if he stayed alive. He also felt that those at home—the mistress, Dao King, Hongjun, Pangu, Fuxi, and the others couldn’t possibly remain unmoved. Surely they were also thinking of ways to save this world.

It was more than saving all of life, it was also salvation for themselves. Thus, Lu Yun bent his mind to modifying the city’s defensive formation. When Wang Shu returned, Yuan Yi decided to take the completely inexperienced boy as her disciple. She taught him the cultivation method of heaven and earth.

The method was a manner of cultivation, not an actual instruction manual. Thus, Yuan Yi was able to use her previous methods to cultivate heaven and earth. Compared to what Lu Yun possessed, Yuan Yi’s knowledge was more suited to the boy.

In any case, Lu Yun was used to leaving his work to others. He was in charge of selecting candidates, Yuan Yi could be responsible for teaching them.

Modifying a formation was a walk in the park for Lu Yun in his current state. He didn’t even need to break the formation’s original structure. He just needed to repair what was broken and then alter it into a formation of heaven and earth.

Its foundations were originally one hundred and eight origin stones—thirty-three of them were broken. The remaining seventy-five were more or less intact, but the energy within them was mostly exhausted.

Based on Lu Yun’s calculations, the formation could endure for another thousand years if it didn’t encounter other pressure. If the ghost zombies kept attacking it, however, it would only stand for another hundred years.

The city would fall when it broke after a hundred years.

For the moment, the formation’s overall structure was more or less intact. Even though it wavered, it didn’t run the risk of collapsing.

“While the formation can hold for one hundred years, the people in the city might not be able to.”

After a day’s worth of repairs, a mystical purple haze appeared before nightfall. The formation had been modified into one of heaven and earth. Since it was assembled into an internal circulation of heaven and earth, the origin stones of the formation regenerated with the cycling of the formation. All sorts of energy continuously transformed into each other.

Such was a reflection of heaven and earth. Living beings were born of heaven and earth and died of heaven and earth. They obtained nourishment from the world and excreted waste that they did not need. This waste, as well as their bodies, nascent spirits, and souls decomposed into heaven and earth when they died. They returned to being pure energy and filtered back into heaven and earth.

Such was a process of reincarnation.

Lu Yun also finally understood where he’d gotten inspiration for the formation of heaven and earth in the world of immortals. It was from the power of reincarnation in the Tome of Life and Death!

He’d fully organized his thoughts and knew how to proceed from here. Lu Yun’s strength noticeably increased after he set up a formation of heaven and earth.

“Setting up formations can help me get stronger?” He sat on the city walls and mused over his thoughts as ghost zombies appeared with the setting of the sun. “Heaven and earth are still alive. In fact, they connected to the formation when I set it up and built the circulatory system. Did I absorb some more energy from the world when that happened?

“No, no. My increase in power isn’t just in terms of strength, but also in terms of mastery over reincarnation. My understanding of strength has risen to greater heights compared to before?” Lu Yun frowned and gently pushed the air.

KABOOM.

An enormous explosion detonated in the distance and obliterated countless ghost zombies. In the next moment, Lu Yun noted a current of black air surging through the void and into his body. The energy that he’d just expended was replenished.

“The circulation of heaven and earth!” His eyes lit up. “I’ve completed the circulatory system and now it circulates externally!”

External circulation meant that the energy he released could be recalled back into his body at any time. Even the ghost zombies that he killed could turn into his strength and be absorbed into his being.

This would be called demonic dao in the world of immortals, but it was a life-saving measure in this world.

Brightening immeasurably, Lu Yun jumped down from the city walls and flung himself into the hordes of ghost zombies. He’d repaired the formation and blocked the gap in the city gates, so the citizens used to rushing for the city gates loitered where they were, unsure of what to do.

With Lu Yun as the vanguard before, a few ghost zombies still occasionally made it through. That would be when the people clubbed the enemy to death. But now, the ghost zombies were completely halted outside of the formation. None could make it in.

The modified formation was much, much stronger than before.
