Chapter 137: Advancement to the Cave Heaven Realm

Soon, Yang Feng's Slaughter Cave expanded beyond its limit, reaching a diameter of one million kilometers.

Generally speaking, the first cave opened by a peak law cultivator has a diameter of only one thousand kilometers.

The Slaughter Cave opened by Yang Feng has a diameter of one million kilometers, which is one thousand times that of the caves opened by other peak law cultivators!

"Ding! You have opened up a killing cave, and the effect of cultivation will be returned ten thousand times. You can choose to strengthen the killing cave by ten thousand times, or you can choose to expand the killing cave by ten thousand times!"

"You have one minute to consider. After one minute, the system will return the ten thousand times effect at will!"

At this time, a crisp reminder sounded in Yang Feng's ears, which made him flash a look of surprise in his eyes. He couldn't help but whispered softly: "I can actually choose the direction of ten thousand times return, which is amazing!"

After a mutter, Yang Feng's brain started to work rapidly.

The killing cave is strengthened by ten thousand times. The killing cave will become extremely powerful. Not only is it extremely solid and difficult to destroy, but the world power generated will also become extremely powerful and pure, which is ten thousand times that of the volume cave world.

The Slaughter Cave Heaven will expand 10,000 times, and its diameter will reach a terrifying 10 billion kilometers, reaching the level of the Thousand Worlds, directly surpassing the Cave Heaven Realm, and being promoted to the Void Immortal Realm, accepting the baptism of the Nine-fold Thunder Tribulation.

"Directly surpassing the Cave Heaven Realm and becoming a Void Immortal Realm cultivator does not mean much to me!"

"After all, the diameter of the Slaughter Cave Heaven has expanded by 1 million kilometers, reaching the level of the Thousand Worlds. Although it can make me a Void Immortal Realm cultivator, it does not increase my combat power much!"

"At that time, I was a Void Immortal Realm cultivator, and I only had the combat power of a Void Immortal Realm cultivator, and I did not have the terrifying combat power of fighting across levels at all!"

"And if I choose to strengthen the Slaughter Cave Heaven by 10,000 times, the Slaughter Cave Heaven world will not only become solid and powerful, Difficult to destroy.

The world power born from the Killing Cave Heaven, whether in terms of quantity or purity, is 10,000 times that of the cultivators of the same level, which allows me to have a combat power far beyond the same level, and even to fight across levels and kill the cultivators of the Void Immortal Realm across levels! "

"In summary, I still choose to strengthen the Killing Cave Heaven by 10,000 times!"

As Yang Feng made his choice, an invisible force appeared out of thin air and entered the Killing Cave Heaven world of Yang Feng's Killing Sea of ​​Consciousness and the Killing Law Crystal, and began to strengthen the Killing Cave Heaven world.

When the invisible force faded, Yang Feng's Killing Cave Heaven was strengthened by 10,000 times, and the world power born was also increased by a full 10,000 times, and it was more pure and powerful.

"Is the beast tide over?"

"We won!"

"The beasts were wiped out!"

"We are alive!"

"... "

When Yang Feng was promoted to a cave-heaven realm cultivator, the guards on the walls of Heiyuan City reacted from their shock and shouted loudly with excitement on their faces, their eyes full of excitement and relief.

"I'll leave the follow-up matters to you. I'll go to practice in seclusion for a while!"

Hearing the excited shouts and cheers of the guards on the walls of Heiyuan City, Yang Feng explained to Zhao Qianyu beside him, and then turned into a stream of light and flew towards the city lord's mansion of Heiyuan City.

Soon, Yang Feng came to the practice room in the city lord's mansion and carefully felt the changes in his body.

"Most of the world power born from the Killing Cave is stored in the Killing Cave. I can mobilize it at any time. A small amount of world power enters my body to strengthen my body."

"At the same time, as the Killing Cave continues to give birth to world power, the Killing Law power contained in the Killing Law Crystal continues to increase."

"Even if I don't practice, the Killing Law power on the Killing Law Crystal will continue to increase with the continuous operation of the Killing Cave."

After feeling the changes in his body, Yang Feng muttered softly.

After a mutter, Yang Feng took out the world seed rewarded to him by Xuantian Sect and the ancient book given to him by Ye Fan.

"It's time to refine this world seed and open up the cave world in my body!"

Looking at the world seed and the ancient in his hand, Yang Feng sighed softly, then mobilized the mana in his body, poured it into the world seed, and began to refine it.

Soon, the world seed was refined by Yang Feng and collected in his sea of ​​consciousness.

At this time, Yang Feng began to use the world seed as a carrier to open up the cave world.

Boom! Boom! Boom!

Accompanied by a series of violent roars, a micro world with a diameter of only 10 kilometers appeared in the world seed and entered Yang Feng's induction body.

"The law power of this micro world is so perfect!"

"It has all the laws of gold, wood, water, fire, earth, wind, ice, thunder, space, destruction, time, life, etc. Compared with the great world, the micro world has relatively weak law power and is too small in size. There is no big essential difference at all!"

"In fact, the micro world is the initial state of the great world. As long as enough spiritual energy is poured into it, it can automatically transform, continue to grow and evolve, and eventually become the boundless great world."

"However, the diameter of the micro world is 10 kilometers, which is too large. A large amount of spiritual energy must be poured into it to let it evolve on its own!"

After sensing the situation of the micro world, Yang Feng's eyes flashed with a gleam of light, and he whispered softly.

While muttering, Yang Feng's mind moved, and the mountains of spiritual stones in the cave bead turned into streams of light, all entering the micro world.

With the influx of countless spiritual stones, countless pure spiritual energy emanated from the spiritual stones, allowing the micro world to continue to expand outward.

The number of spiritual stones in the cave bead is extremely large, and the spiritual energy contained is also extremely terrifying.

However, the micro world has perfect laws, and the difficulty of evolution is extremely high. Every meter of expansion requires extremely huge and terrifying spiritual energy.

Therefore, when the spiritual stones of the cave bead were all absorbed and swallowed by the micro world, the diameter of the micro world only expanded three times, reaching 3 kilometers.

Seeing this scene, Yang Feng frowned slightly, and after a little thought, he moved his mind and moved the Yanshan in the cave bead to the micro world.

Boom! Boom! Boom!

At this moment, a series of violent roars sounded in the micro world.

The Flame Mountain, which never extinguishes and contains mysterious flame energy, was destroyed by the laws of the micro world as soon as it entered the micro world, turning into a large amount of spiritual energy, which was infused into the micro world, causing the micro world to expand outward frantically.

When the spiritual energy and mysterious flame energy contained in the Flame Mountain were absorbed by the micro world, the diameter of the micro world directly expanded by one thousand kilometers.

At this time, a series of terrifying pressures emanated from Yang Feng's sea of ​​consciousness, pressing on his body, making him feel a little unable to hold on.

Seeing this scene, Yang Feng did not hesitate at all, and immediately swallowed and refined all the life springs contained in the ancient body, allowing his body to rapidly strengthen so that he could withstand the terrifying pressure from the sea of ​​consciousness.

"Ding! You have opened up a cave world, the effect of cultivation is returned ten thousand times, and your cave world has expanded ten thousand times!"

With a crisp reminder sound, Yang Feng's ears rang, and an invisible force entered the micro world, causing the micro world to expand rapidly, and finally became a cave world with a diameter of 10 million kilometers.

When the invisible force faded, a strong and perfect world force emanated from the cave world, entered Yang Feng's body, and began to strengthen Yang Feng's body, making his physical strength stronger, and the essence of life also transformed.

At the same time, the gold, wood, water, spirit, earth, wind, ice, thunder, space, and destruction law crystals in Yang Feng's sea of ​​consciousness were also strengthened by the world force emitted from the cave world, and the law force contained in it became more rich and powerful.

When Yang Feng's body and the law crystals in his sea of ​​consciousness were strengthened by the world's power, Yang Feng was officially promoted to a cave heaven cultivator, and he was a peak cave heaven cultivator.

As long as Yang Feng expanded the diameter of the cave heaven in his body a little and promoted it to a thousand worlds, he would be baptized by the nine-fold thunder tribulation and promoted to a virtual fairyland cultivator.
