The prehistoric world is boundless, with only one Qingyu Mountain, which is thousands of miles in a radius. Lei Ming left the tribe and took him a few days to walk out of Qingyu Mountain.

Leaving Qingyu Mountain, Lei Ming was a little confused and didn't know where to go. He looked back at Qingyu Mountain, this inconspicuous mountain range in the prehistoric world, was his home after all!

"I didn't expect that I would be so sad." Lei Ming shook his head and soon became determined. He looked at the sun in the sky and decided to go east.

Lei Ming sat on the back of the Golden Crown Eagle and flew eastward, but the Golden Crown Eagle was not as fast as in the world of mortals.

The space in the prehistoric world is very stable, and only the Daluo Golden Immortal can shake the space. As for the space teleportation array brought back by Lei Ming, it cannot be deployed. The formation level is too low and it cannot be broken through the prehistoric space.

In the world of mortals, the speed of the Golden Crown Eagle is equivalent to teleportation, but in the world of prehistoricity, it can only fly thousands of miles a day at most. But even so, it is faster than Lei Ming's escape method.

When you are on the way, Lei Ming will comprehend the formation. The formations in the mortal world are not complicated, and you can quickly understand them as long as you spend your time thinking. However, these can only be regarded as the basis of the formation.

Even though Lei Ming did not practice deliberately, the spiritual power of the prehistoric world was rich, and in a few months, he reached the peak of the early stage of the God Transformation.

"The Five Elements Practice has reached its extreme. If you want to make a breakthrough, you can only try to deduce it yourself." Lei Ming thought helplessly. He stopped comprehending the formation, observing the creatures during the day, observing the starry sky at night, watching the sun rise and set, and the moon wanes and full moon, trying to learn from nature.

Lei Ming flew for a whole year but didn't meet a single person. He simply descended and walked into the mountains. What surprised him was that he did not encounter any danger along the way.

"At this time, the prehistoric world should be occupied by the two lich tribes. There are few people in the witch tribe, and it is understandable that they can't be met. But there are many demon tribes, why can't they see them?" Lei Ming was still confused. He didn't know that if it weren't for Di Jun taking into account the saints and ordered the demon tribe to temporarily evacuate thousands of miles from Buzhou Mountain, how could Lei Ming be so stable?

Three years have passed, five years have passed...

"It is said that there are countless powerful people in the prehistoric world, why can't I meet any of them?" Lei Ming was a little discouraged, "Does I not have this opportunity?"

Although disappointed, Lei Ming did not stop, but his sense of expectation slowly disappeared. After walking for more than ten years, Lei Ming came to the foot of a beautiful mountain. At sunrise, the mountain clouds were everywhere in the sky, and at sunset, the red clouds covered thousands of miles. The mountain was rich in spiritual energy, the plants and trees were clear, and the eagles flew and apes were crying. It was really a wonderful place!

Lei Ming decided to live in this mountain for a while, and he arranged a formation at the foot of the mountain. The Five Elements Formation set by Lei Ming was not exquisite, but it was also very powerful when arranged by spiritual objects from the prehistoric world.

The Five Elements Formation is 100% complete, and the Five Elements Spiritual Power rolls like waves, vibrating all directions.

Lei Ming built a hut on the mountain, and there were a lot of spiritual medicines in the mountain. He transplanted the spiritual medicine he was interested in to the Five Elements Space. The Five Elements Space was full of various spiritual medicines, and the spiritual medicines were fed back to the space, and the spiritual power in the space was already very considerable.

"Now the spiritual power of the Five Elements Space is no less than the holy place of cultivation in the mortal world, but it is nothing in the prehistoric world. It's just that the level of the Five Elements Space is too low and cannot accommodate more spiritual power."

Lei Ming knew that with his current realm, the five elements space had reached its limit.

Thunder Ming looked at the clouds in the morning, the sunset in the evening, and experienced the vastness of the world, and gradually gained new insights. He immediately went into seclusion and deduced his skills. More than 30 years later, Thunder Ming finally succeeded and successfully broke through to the middle stage of the God Transformation.

Just as the thunder broke through, a colorful mist suddenly appeared behind the mountain. Then a fragrance filled the air, which was strong but not greasy, plain and elegant, making Lei Ming intoxicated.

"A treasure is born!" Lei Ming was very surprised. Legend has it that there are treasures everywhere in the prehistoric world, but he has never seen them before. Now he finally met them. Lei Ming couldn't help but feel excited and turned into rainbow light and headed towards the back mountain.

In the back mountain, a green tea tree stretches its leaves, and mist is filled with it. The mist is slowly absorbed by it and turns into white frost covering its leaves.

"This is the acquired spiritual root!" Lei Ming felt that he had won the grand prize when he saw the tea tree. There were a lot of acquired spiritual roots in the prehistoric world, but most of them were occupied by those powerful people in the famous cave world. The probability of the acquired spiritual roots appearing on such a mountain is no higher than the grand prize in the previous life!

The so-called spiritual roots are special spiritual objects. These spiritual objects are born in accordance with the fortune of heaven and earth, and each species has special mystery.

Spiritual roots are divided into acquired and innate. Innate spiritual roots are transformed by laws, with very few numbers. Some have transformed into shape and become truly powerful people. The most famous one is the Western Saint Cundi, whose essence is Gengjin Bodhi, and innately masters the origin of part of the metal.

The acquired spiritual roots are born from the acquired, and there are very few laws, but they can suppress the fortune. The caves of the prehistoric world generally have acquired spiritual roots. There are many acquired spiritual roots, and the gap is also very large. They are divided into top-grade, top-grade, middle-grade and low-grade.

Lei Ming's spiritual consciousness communicated with the tea tree and learned its information. This tea tree is called the White Frost Tea Tree, the lowest acquired spiritual root.

Although it is only a low-quality product, Lei Ming is already very satisfied.

The white frost tea tree has just matured and its spiritual intelligence is still very weak. Lei Ming took the opportunity to move it into the five elements space. The white frost tea tree planted into the five elements space, and Lei Ming immediately felt that the five elements space was much stronger.

Lei Ming's heart moved, and the power of the five elements burst out, breaking the surroundings of the five elements space, and the space began to spread everywhere and expand. After a few months, the originally radius of the five elements space had expanded to a radius of thousands of miles, and it had increased many times.

"It is worthy of being the acquired spiritual root!" Lei Ming was overjoyed, the five elements space grew, his understanding of the origin of the five elements further deepened, and he deduced the five elements exercises of the entire realm of the God Transformation Realm in one breath.

A year later, Thunder reached the perfection of the God Transformation Period.

"It's true that you're going out for a trip. If you just hide in Qingyu Mountain, when will you have such an opportunity?"

After breaking through, Lei Ming had already planned to leave. He had searched all over the entire mountain and had no other treasures. Lei Ming, who had benefited, decided to go to other mountains to explore.

Lei Ming was about to go down the mountain when he suddenly saw the human race at the foot of the mountain. He saw the man bowing piously at the foot of the mountain and said, "Disciple Xuandu, I am dedicated to seeking the Tao and ask my seniors to preach the mission."

"Xuandu!" Lei Ming was so shocked that he almost fell down. He was sure that he had heard it correctly. Looking at the ragged young man, Lei Ming suddenly remembered.

"In myths and legends, the only personal disciple of the Taiqing Saint, Master Xuandu, is the human race. It is said that in order to seek the Tao, Xuandu traveled alone in the prehistoric world and worshiped the mountains when he saw the mountains, and finally worshipped under my sect."

Lei Ming went to Xuandu again. Although the other party was just a mortal, he had a firm mind and his temperament was in line with nature, which was very extraordinary.

"He should be the Great Master Xuandu, right?" Lei Ming said intimately, and was also a little excited. Xuandu had not yet worshipped under Taiqing's sect. If he followed him, would he have the chance to worship the People's Sect?

Although Lei Ming had an adventure, he was not arrogant. In the world of mortals, the reason why he rejected Li Yuanhua twice was that Li Yuanhua's realm was too low, and the second was that the master and disciple had a very heavy cause and effect, which was not just a matter of worshipping.

If you encounter a powerful master who accepts disciples in the prehistoric world, Lei Ming will definitely not refuse!

Thinking of this, Lei Ming opened the formation, Shi Shi suddenly went down the mountain, and appeared in front of Xuandu.

"Disciple Xuandu, the human race, is dedicated to seeking the Tao, please ask seniors to preach the Tao!" Xuandu was still piously apprenticing to the master, and Lei Ming hurriedly went aside. He did not dare to accept Xuandu's worship.

"I didn't expect Xuandu to be an ordinary human race."

Lei Ming was a little surprised. He originally thought that even if Xuandu was not a congenital human race, he should be an acquired human race, but after seeing it clearly, he realized that Xuandu was just a human race with ordinary bloodlines.

"I actually took an ordinary human race as my personal disciple and trained him to become a powerful person. The saint's methods are really terrifying!"

Xuandu was still worshiping the mountain, and Lei Ming held him with his hands.

"Let's wait!"

Only then did Xuandu see thunder, and a smile appeared on his face full of wind and dust. He had been wandering in the prehistoric world for nearly a hundred years and had worshipped countless mountains. This was the first time he saw an immortal on the mountain.

"I beg you to preach the mission!" Xuandu said.

Lei Ming did not ask him to bow down: "Young friend doesn't have to do this, I am also a human race."

Xuandu was even happier. The human race in this era is very united.

"I really admire your firmness in seeking Tao. I also have some Taoisms. If my friends are willing, they can comprehend it with me."
