Chapter 137: Advancement to the Cave Heaven Realm

Soon, Yang Feng's killing cave expanded to its limit, reaching a diameter of one million kilometers.

Generally speaking, the first cave opened by the peak law cultivators is only a thousand kilometers in diameter.

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

"Ding! You have opened a killing cave, and the cultivation effect is 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, making 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. It's amazing!"

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

The Killing Cave Heaven will be strengthened 10,000 times, and it will become extremely powerful. Not only will it be extremely solid and difficult to destroy, but the world power it generates will also become extremely powerful and pure, 10,000 times the volume of the Cave Heaven World.

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

"Directly crossing the Cave Heaven Realm and becoming a Void Immortal Realm cultivator does not make much sense to me!"

"After all, the diameter of the Killing Cave Heaven has expanded to one million kilometers, reaching the level of the Small Thousand Worlds. Although it can make me a Void Immortal Realm cultivator, it does not increase my combat power too 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 Killing Cave Heaven 10,000 times, the Killing Cave Heaven world will not only become solid and powerful, Difficult to destroy.

The world power born from the Killing Cave Heaven is 10,000 times that of the cultivators of the same level, both in terms of quantity and purity. It allows me to have a combat power far beyond the same level, and even to fight across levels and kill cultivators in 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 Yang Feng's killing sea of ​​consciousness, the Killing Cave Heaven world of 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 survived!"

"... "

When Yang Feng was promoted to a cave-heaven realm cultivator, the guards on the walls of Black Abyss City reacted from their shock, shouting 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 Black Abyss City, Yang Feng explained to Zhao Qianyu beside him, and turned into a stream of light, flying towards the direction of the City Lord's Mansion of Black Abyss City.

Soon, Yang Feng came to the underground practice room of the City Lord's Mansion and carefully felt the changes in his body.

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

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

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

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

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

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

Looking at the world seed and ancient jade in his hand, Yang Feng sighed softly, and then encouraged 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 stored in the sea of ​​consciousness.

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

Boom! Boom! Boom!

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

"The power of the laws of this micro world is so perfect!"

"The laws of gold, wood, water, fire, earth, wind, ice, thunder, space, destruction, time, life, etc., are all available. Compared with the great world, the micro world is not much different in essence except that the power of the laws is relatively weak and the size is too small!"

"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 of ten kilometers is too small. 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 to 30 kilometers.

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

Rumble! Rumble! Rumble!

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

The Flame Mountain, which never extinguishes and contains mysterious flame energy, is destroyed by the laws of the micro world as soon as it enters the micro world, turning into a huge amount of spiritual energy, which is poured into the micro world, causing the micro world to expand outward crazily.

When the spiritual energy and mysterious flame energy contained in the Flame Mountain are absorbed by the micro world, the diameter of the micro world directly expands to 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 jade, allowing his body to rapidly strengthen and withstand the terrifying pressure from the sea of ​​consciousness.

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

With a crisp reminder sound, it sounded in Yang Feng's ears, and an invisible force entered the micro world, causing the micro world to expand rapidly, and eventually became a cave world with a diameter of ten million kilometers.

When the invisible force faded, a strong and perfect world force emanated from the cave world and 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 ten law crystals of gold, wood, water, fire, earth, wind, ice, thunder, space, and destruction in Yang Feng's sea of ​​consciousness were also wrapped and strengthened by the world power emanating from the cave world, and the law power contained in them became more intense and powerful.

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

As long as Yang Feng expands the diameter of the cave world in his body and is promoted to a small world, he can obtain the baptism of the nine-fold thunder tribulation and be promoted to a virtual fairyland cultivator.
