"I'll tell you about this thing later, let's cultivate first. The medicine man immediately passed away.

"Since you said that this is the exercise I created, then I should give it a name, and I actually want to absorb the spiritual flame, then I will call him "Spiritual Flame Decision". With that, Yao Yan took out the charcoal pen from the storage ring and wrote the words Spirit Flame Decisive on the book cover.

"This Spirit Flame Determination is said to be able to reshape the meridians, but no one has ever cultivated successfully, and naturally no one knows whether it is true or not. The Spirit Flame is a treasure that everyone in the other world dreams of, and its rarity can be imagined. Every Spirit Flame is an extremely tragic battle and battle, and the absorption process is extremely dangerous, but there are still countless people who are crazy about it. I was lucky enough to find this cluster of flames in the Endless Wasteland, and although I was fully prepared, I was lucky enough to save my life. In fact, it is my consciousness to let you practice the Spirit Flame, and I hope you can save us. But if you are not willing to embark on this extremely dangerous cultivation path, my Alien Fire Determination is a low-level Immortal Rank Exercise, and it can also make you a generation of powerhouses, and I will still teach you wholeheartedly. The medicine man summoned Hei Yan and hesitated for a moment, then conjured up a book of exercises called the Strange Fire Technique and handed it to Yao Yan.

In ancient times, there was only one world, and no one knew the origin of human beings. But a group of immortal cultivators gradually emerged, and these immortal cultivators relied on the powerful heaven and earth energy in ancient times to cultivate extremely strong cultivation. But because of the comparison and strife, the greed in their hearts is more vigorous, from forming gangs to establishing families, everything is open and secret. In the end, the battle of the immortal cultivators still suffered from these civilians, some of them were captured as slaves, some were taken to feed the demonic beasts raised by the immortal cultivators, and some women with good faces were even reduced to playthings. In this troubled era that has lasted for tens of thousands of years, I don't know when a genius appeared, and he cultivated to be amazing, talented, and beautiful, and compassionate. In the end, in his lifetime, he actually studied the martial arts that could create the world, and finally saved all the mortals in the world with the power of one person.

This genius moved everyone into his own world, and rested with them from sunrise to sunset. Until he saw that his friends, his relatives, were aging one by one, and he had endless cultivation and thousands of years of life. This person then created the Spirit Flame Duel, using its power to blast open the blocked meridians of the people he cared about, and then create bloodlines for him, so that he could cultivate and have the ability to prolong his life. But his ability is limited, and in the end, he only won a situation for hundreds of years for everyone.

Thousands of years later, the cultivators of the Great World had exhausted the True Qi in their world, and the forces that eventually controlled the most True Qi gradually eroded the forces of all sides, and this process even lasted for hundreds of years, until they remembered that there was once a person who created a world. The various forces began to cooperate to find the children who survived and were still in the big world, and prepared to send them to that world through the cultivation and wisdom of everyone. In the end, they used their parents to coerce each other, so that this child successfully came to this world, and got the martial arts they wanted to create the world. The various families in the big world have sent their clansmen into the world created by each family, and there are even some who directly bring the entire family into the small world. The biggest force saw these fat sheep slipping away one by one, and naturally they wouldn't let them get their wish. Their family used the sacrificial technique to sacrifice half of the world's immortal cultivators to connect the various small worlds, greedily sucking true qi. Until there is no true qi to absorb, the human mind is like this, and once the desire starts, it is very difficult to stop. So this person placed a prohibition, once someone exceeds a certain realm, it will attract a thunder tribulation that is enough to destroy the world, and after killing him, he will obtain his true qi. Over time, it was difficult for a strong person to appear in the small world, until a small number of people escaped the thunder tribulation through the naturally generated Heavenly Spirit and Earth Treasure.

When the man learned that someone had successfully crossed the tribulation, he gladly accepted it, and since he could avoid the thunder tribulation, he still had some ability to give him a way out. In the end, the man set up four thunder tribulations in a row, and gave the last person some reward - to fly to the great world and get true freedom. The man knew that he was invincible to the world, and slowly regarded this sentient being as a game, and the world would live if he won and die if he lost. The man had seen a lot of things, and he had come to enjoy the sense of calculation and foresight. It felt like he was in control of everything, until one day he would fight someone and lose both, and maybe even die. So he found the genius and fought a great battle. In the end, the genius was outnumbered, and used his last strength to completely isolate the world he created from the big world.

Although this genius was mortally wounded, he relied on his extraordinary cultivation to keep himself alive. It wasn't until hundreds of years later that the immortal cultivators of this world began to fight, plunder, and brutalize, and he didn't want his world to become as inhuman as the big world. I finally made up my mind and set up a Stonehenge with two hundred boulders. The genius used Stonehenge to destroy the cultivation of all the people in this world and the bloodline used for cultivation, and killed all the demonic beasts that would endanger mortals who could not cultivate immortals. Then he used his powerful True Qi to condense the vast universe that appeared, and finally lowered his arrogant head, letting time mercilessly weathered his remains.

However, some of the cultivators in this small world fell into the water from a high altitude, some flew far away and didn't have time to return home, and some even fell to their deaths in the wilderness and were devoured by demonic beasts. These scattered groups of people gradually formed their own languages and scripts by virtue of their own habits of speaking and writing, and established their own tribes, through slave societies, states, dynasties, republics, and now the United Nations. And those monsters that were bombarded tens of thousands of years ago were forgotten by people over time, and it wasn't until the establishment of the tech tree that they remembered those forgotten monsters. Those demonic beasts also had a new name—dinosaurs, and that genius was Yao Yan's previous life.

After thousands of years of time, Yao Yan's previous life soul finally recovered to the energy that could be reincarnated. In the end, he gave up all the memories of his relatives, lovers, and friends in his previous life and entered the next reincarnation.

This is the book that was stolen by the child, who lived for hundreds of years and gave birth to a baby, and did his best to raise it to adulthood. After a thousand years, the child still became a strong man, using his own bloodline to reincarnate Yaoyan's dying soul in a sub-world. And at the cost of his own life, he sent the infant who had grown up to Yaoyan to guide him, hoping that this time he could save all the people in the world.
