In addition, Ling Feng's mount, the little white dragon, has finally been promoted to the realm of the primordial gods, and his bloodline has been improved to a certain extent, and he can barely take a shot.

At this time, the forces under Ling Feng's command could be said to have increased to a large level. A Martial Venerable powerhouse can develop a third-grade sect, and Ling Feng already has more than 10,000 Martial Venerable powerhouses under his command, as well as two saint-level subordinates with combat power, and his strength has far exceeded that of a big force like the Great Qian Dynasty. If you add Ling Feng and his Xuanyin clone, the strength is already close to the sect at the bottom of the thirty-six holy lands.

Some of the Sacred Land Sects at the bottom of the rankings, the strongest is the Peak Saint Lord, plus an eighth-order immortal weapon, it may not be as strong as Ling Feng's.

However, Ling Feng's burden at this time was also very large, the three Martial Saint powerhouses and more than 10,000 Martial Venerable powerhouses were all cultivating in the Mixed Yuan Bead, and they needed to exhale a terrifying amount of vitality every moment. The families of the other 10,000 soldiers have grown to more than 60,000 people, and the daily necessities they need to consume are also extremely terrifying. If it weren't for the Mixed Yuan Bead absorbing the earth's leyline vitality every day, it would probably not be able to hold on. And once the origin of the cave world is insufficient, it will collapse.

At present, it is already a very dangerous state, and the population must be controlled, unless the Mixed Yuan Bead is promoted to the ultimate holy weapon, and the origin of the cave heaven will increase significantly.

At this time, there were nearly 60 years left in the eight hundred years, and Ling Feng was ready to deduce the method of opening up the Cave Heaven.

There are several ways to open up the cave sky, the first is the spiritual platform creation, that is, the virtual spiritual space opened up by the primordial gods, with the mana filling, little by little from the virtual to the real, into a real world. This method is simple, safe, and time-consuming. First abandoned by Ling Feng.

The second method is to aggregate the acupoint space in the body and evolve it into a huge space, as the prototype of the cave sky, this method is slightly faster.

The third method is to condense the origin of the mixed cave with majestic mana, and then use the method of Pangu to open the heavens and open the heavens and the earth, and differentiate the turbidity, yin and yang.

This method is basically the Chaos Demon God, and this is the only method recorded in the Chaos True Body Formula. However, opening up the world is a dangerous job, if the cave is too big and beyond your ability, then you can only end up with Pangu and incarnate all things in the world. If you are worried and afraid, the cave is too small, and the "expansion" of the cave will take a lot of time in the future. Therefore, Ling Feng had to try it out in the system practice room before opening up the cave.

In addition, after the cave is opened, there must be treasures to settle the land, wind, water and fire, otherwise the cave world will keep expanding, and then shatter like a balloon. In addition, the structure of the cave must be decided first. It is generally divided into the type of planet and the type of crystal wall plane in the round sky.

No matter how big the planet type is, there is an end, and with continuous discovery, a vast galaxy will eventually be formed.

And the limit of the plane type is the type of the Three Realms of Heaven, Earth and Man in the Flood World.

As a martial arts cultivator, Ling Feng naturally chose the second Three Realms type.

Immediately, Ling Feng began to immerse himself in the system practice room, comprehending the method of opening up the Cave Heaven.

Time has passed, thirty years have passed in a blink of an eye, and in the 1500 years of deduction in the system practice room, Ling Feng has finally achieved the confidence of opening up the cave.

Immediately, Ling Feng began to open up the cave sky, and the location of the cave heaven was chosen as the dantian, and based on the space of the dantian acupoint, he began to condense the chaotic mana.

As his chaotic mana continued to condense, an infinitesimal hole, or singularity, gradually formed.

Just like before Pangu opened the sky, chaos was like a chicken. However, opening up the cave sky is not many times easier than opening the heavens and the earth, and there is no pressure from the Chaos Sea, and there is no need to open the heavens with an axe, he took out the Chaos Immortal Sword and suddenly swung the sword and slashed it.

With a bang, the singularity of the chaotic hole suddenly exploded, the surging turbidity two qi expanded infinitely, the turbid qi floated up and the turbid qi sank, seeing that the space where the turbid two qi expanded reached the size he expected, Ling Feng suddenly urged the chaos bell, and as soon as the bell rang, the turbidity two qi stopped expanding.

At this time, the clear qi begins to evolve into the stars, and the turbid qi begins to evolve into the earth.

However, when heaven and earth first opened, the original spatial barrier was no longer enough to act as the fetal membrane of heaven and earth, so he used chaotic mana and chaotic dao essence to retrain the fetal membrane of heaven and earth. At this point, he had practiced thousands of times in the system practice room, and soon re-refined the fetal membrane of heaven and earth.

Immediately, Ling Feng used the power of the Yin and Yang Dao to control the turbidity and two qi, condensing the thirty-six layers of Tiangang atmosphere and the seventy-two layers of earth turbidity qi respectively, as for the Zhou Tian stars, they were all illusory for the time being, only the two stars of Taiyin and Sun were quite weighty, responsible for the alternation of day and night.

And in the middle of the earth, a land of 800 miles and an ocean of 300 miles have also been formed, and beyond is the illusory ocean, waiting for mana to fill the creation.

At this time, the Heavenly Realm and the Underworld had not yet taken shape, but he had already left room for it, the space of Zhou Tianxingchen was the future Celestial Realm, and the remaining space below the seventy-two layers of Earth Turbidity Qi was the future Underworld.

The newly opened Cave Heaven had a continent of eight hundred miles in length and width, as well as a sea area of three hundred miles, which was three or four times more powerful than ordinary Holy Lord powerhouses. However, the consumption of mana is also extremely large, and his cultivation at this time has already lost eighty percent, if it weren't for his own cultivation equivalent to the peak of the Holy Lord, and relying on the recovery of the vitality of the Chaos Bell, he would have died of exhaustion.

Immediately, while Ling Feng slowly resumed his cultivation, he kept adding various Great Dao Laws to Heaven and Earth to stabilize this nascent Cave Heaven World.

The Holy Lords who had just broken through were the weakest, as most of their mana was thrown into the Cave Heaven. And in order to maintain the stability of the cave sky, it is not possible to extract the origin of the cave heaven at will. Only when the cave heaven is stable and gradually grows stronger, will the Holy Lord's combat power live up to its name.

Immediately, while Ling Feng continued to consolidate this fledgling world, he also extracted the chaotic vitality of the Chaos Bell and restored his mana cultivation.

It took ten years for Ling Feng to completely stabilize the Cave Heaven, and after another ten years, he regained his mana.

At this time, time was about to flow to the time when Ling Feng entered this realm. At this time, Nezha had been punished to the lower realm and reincarnated as Bao Ren.

At this time, Ling Feng was also thinking about whether to plan again in this world. For example, Nezha's Qiankun circle and Guanyin's jade net bottle, these two should be real immortal weapons, the Qiankun circle is an offensive type, and the net bottle is an auxiliary magic weapon, but the grade is higher, it can absorb the water spirit between heaven and earth, condense the elixir jade liquid, its mana can bring the dead back to life, and the elixir jade liquid inside can make people immortal. Hangzhou City has been in drought for 23 years, not because of Bao Ren, but because the net bottle keeps absorbing the water spirit between heaven and earth, if the net bottle is broken, the rain inside will be released, enough to flood Hangzhou City.

And whether it is the Qiankun circle or the net bottle, there are people watching, among which the dragon descending Arhat Jigong is only obvious, and there is Guanyin secretly. There is not much hope of wanting to take the two pieces together, just waiting for the opportunity to take the other one when there is an opportunity.

Therefore, Ling Feng hid in the underground of the Valley of Forgetfulness with the Mixed Yuan Bead to cultivate, waiting for the opportunity.
