Lin Xinyu and the others returned to the Netherworld Empire, came to the inn, and after resting for a few days, they went to the Netherworld Empire's teleportation array, preparing to teleport back to the Longshan Empire. After paying the spirit stone, the teleportation array was opened, and after the last transmission, Lin Xinyu and the others also adapted to the dizziness during the teleportation.

After returning to the Longshan Empire, he entered the Trial Pavilion in the Chaos Heavenly Sect and delivered the trial man task. "Is there a place for the Chaos Heavenly Sect to organize and collect intelligence and ancient history?" Lin Xinyu asked. He wanted to learn about the transformation of the demon beast, so that he could understand the future transformation of the Hell Heavenly Demon Dragon. "I don't know, the sect's token only introduces the sect's pill pavilion and trial pavilion, martial arts pavilion, and martial arts ring, and does not mention the place of intelligence and ancient history?" The old man in the trial pavilion looked at Lin Xinyu and the others and said, "The information and ancient history of the Chaos Heavenly Sect can be exchanged through the sect's contribution in the trial pavilion!, what do you want to know?" Lin Xinyu said, "The junior wants to know about the transformation of the demon beast!"

"Three hundred sect contributions! If you need to exchange it, hand over the sect token!" the old man said. "Seniors, juniors don't contribute enough, do the sect recycle martial arts and weapons and pills to exchange for sect contributions?" Lin Xinyu said. "Yes, most of the weapons at the Xuan Soul level can't be exchanged much, and those above the spirit level are determined according to the grade and special attributes. It's the same with martial arts!, what do you want to exchange?" the old man asked.

"This is a sword formation martial art obtained by chance by the juniors, and after it is cultivated, it can be a terrifying sword formation, and I don't know the grade very well!" Lin Xinyu said. "I'll take a look!" The old man took the martial art and said, "I can't see through the grade, it shouldn't be an ordinary product, are you sure you want to exchange it?" "This martial art of the predecessor is the same book I engraved from the soul, not the original, let's exchange it!" Lin Xinyu said. "Because the grade of this martial art is uncertain and the martial arts are extremely profound, are you willing to exchange it for three thousand?" asked the old man of the Trial Pavilion.

"Okay, then Lin Xinyu's sect token has an extra three thousand sect contributions. Lin Xinyu immediately exchanged all the information about the transformation of the demon beast. After deducting Lin Xinyu's contribution from the three hundred sects, the old man gave him a quick Yu Jian and said: "The jade slip records all the things about the transformation of demon beasts and the things needed for transformation, and there are still things that need attention, you only need to invade the power of the divine soul into the jade slip, and this memory will be burned into your brain, and after the completion of the jade slip, you can deliver it to me!"

After Lin Xinyu was burned and handed over to the old man, he and Ape Fei both returned to the palace, and Lin Xinyu sorted out the memories of the demon beast transformation in his mind, only to know that the demon beast needed to reach the soul return mirror in order to transform the demon body. When the soul returning mirror breaks through, the divine soul returns to the avenue of heaven and earth, melts the laws of heaven and earth, condenses the Dao intent of heaven and earth, and casts an immortal divine body. Demon beasts only have one chance to transform in their lives, and that is the Soul Mirror, and after failure, they can't transform into a human body and get rid of their own demonic energy. The ten ancient holy beasts, the one with a strong bloodline is born with a heavenly mirror, and it can transform into a human body after birth, and in the Middle Ages, the five great divine beasts were born with a strong bloodline, and only the divine soul mirror, most of them are human soul mirrors, and they still need to be cultivated for a long time before they can be transformed. In ancient times, the four divine beasts were even more pitiful, and they were born with the strength of the Kankan Soul Source Mirror, which was nothing more than a stronger point than the human body, and most of the divine beasts in the Middle Ages were tamed by people or died halfway, and very few achieved the status of demon saints.

The transformation of demon beasts requires the strong Heaven and Earth Qianyuan True Qi and the Demon Domain Transformation Tianchi to carry out the transformation. When the demon beast reaches the Soul Returning Mirror, it can go to the Transformation Heavenly Pool in the Demon Saint Mountain Range of the Demon Domain to transform into a human body. When human beings break through the Soul Returning Mirror, the divine soul will return to the Great Dao of Heaven and Earth, merge the laws of heaven and earth with their own condensation of heaven and earth, and forge an immortal divine body. When the demon beast breaks through the soul return mirror, the soul returns to the great middle of the avenue of heaven and earth, melts the laws of heaven and earth and condenses the Taoist meaning of heaven and earth, and uses the power of transformation Tianchi to shed the demon body, cast a new human body and remove its own demon energy, and complete the transformation. At this time, the demon beast needed a large amount of Qianyuan True Qi and Qianyuan Spirit Stone to wash away the demonic qi in the body and transform the demon soul, so no demon beast dared to rashly transform without adequate preparation.

After reading this memory, Lin Xinyu saw that this change Chi Yanhu also had a little headache, although there are also a lot of Qianyuan spirit stones in the family, but Lin Jiameng can get 300,000 Qianyuan spirit stones every year after removing the annual expenses, it should be able to, and it will be said when it reaches the soul return mirror. Looking at the Hell Heavenly Demon Dragon who was lying on the ground at this time, he thought, when will I be able to reach the Soul Returning Mirror and cast the Immortal Divine Body.

Lin Xinyu looked at the Hell Demon Dragon again, walked out of the palace, went to the Trial Pavilion, exchanged for half a month's cultivation time in the Chaos Qianyuan Pool, and entered the Chaos Qianyuan Pool to cultivate. Half a month later, when Lin Xinyu came out, his cultivation was already in the middle of the eightfold soul source mirror, and at this time, Ao Tianyu had already crossed the hurdle of the human soul mirror, mastered the will of the sky, and successfully stepped into the first weight of the human soul mirror. At this time, there were still three months before the big competition of the sect, and the young man who was fighting with Lin Xinyu that day had already broken through the soul source mirror and reached the double level of the human soul mirror, and comprehended the will of the snow.

At this time, Ao Chun looked at the palace where Lin Xinyu was in the distance and said in a low voice: "There are still three months! In three months, I will use your blood to wash away the shame of that day's invincibility! Lin! Xin! Yu! You wait! No matter how strong the heart of martial arts is, I will also use absolute strength to break your heart of martial arts when the sect is in the big competition! Wait!"

At this time, Lin Xinyu came to the Pill Pavilion, and saw the middle-aged man in charge of the Pill Pavilion, who was about forty years old, but his aura was extremely strong, and he should be the same as the Second Elder Red Ghost, a master of the Heavenly Soul Mirror. "Junior Lin Xinyu is here to exchange for some Xuan Soul-level pills that assist in cultivation!" "Auxiliary cultivation is divided into pills to improve martial cultivation and short-term martial cultivation to absorb Qianyuan True Qi, as well as pills to improve the physique of the human body, what do you need, and the pills for auxiliary cultivation are all spirit level and not Xuan Soul level pills!" The middle-aged man said. "The highest contribution of one for the third grade of the spirit-level pill below the third grade is eight hundred, the highest contribution of one thousand sects above the third grade of the spirit level is below the sixth grade, and the highest contribution of the sixth grade to the ninth grade of the spirit level is three thousand!"

Lin Xinyu was also a little shocked when he heard this number, he thought that three thousand contributed a lot, but it turned out that if he didn't use it, a spirit-level elixir would reimburse three thousand contributions. "The junior wants to exchange for three spirit-level three-grade pills to improve cultivation!" "Okay! Take these are three spirit-level three-grade human soul pills, the human soul mirror cultivation can be directly increased by one level, and the soul source mirror can be increased by two, if it is swallowed at the ninefold peak of the soul source mirror, it will have no effect." The middle-aged man said.

After Lin Xinyu took the Dao pill, he returned to the palace of the outer disciples.
