Xuanming Immortal Destiny
The Underworld Star was originally a world of beasts. For millions of years, the eight great beast clans had been fighting each other all year round. Blood flowed like rivers on the Underworld Star, forming an endless sea.
10,000 years ago, the Xuan cultivators killed their way into the Netherworld Star, exterminated Qiongqi, killed Taowu, exiled Taotie and Hundun, and captured the Azure Dragon, White Tiger, Vermilion Bird, and Black Tortoise.
10,000 years later, the world of war descended once again.
The story began here.
Hong Tian was a fourteen or fifteen-year-old youth, a servant disciple of the Myriad Dao Sect's Spirit Plant Hall. He had the reverse spirit root of water and fire, and was at the first qi layer.
He was aloof from worldly affairs. He only wanted to cultivate to the fourth qi layer so that he would be qualified to go down the mountain to train and meet his grandfather, whom he had not seen for many years.
However, the senior brother who was close to him suddenly died. He lost his identity as a servant of the Spirit Plants Hall and returned to the outer sect.
He wanted to help his senior find out the truth, but the news was leaked and he fell into someone else's trap.
Fortunately, not only did he discover that he possessed the Wind Spiritual Root, but he also obtained a cultivation method for the Wind Spiritual Root.
He cultivated day and night.
He fought with his enemies to the death.
One by one, his enemies were reduced to dust.
Until one day, a beast tide broke out. The 10,000-year crisis of the Netherworld Star had arrived!
With his extraordinary ability, Hong Tian gradually walked to the front of the Celestial Gate and the four Beast Gods. He suppressed the Beast Tide and protected the heavenly world. Even if he was attacked by the axe, he was fearless!
He was Hongtian!
Cultivators loved and feared him, mortals worshipped him, and in the vast world, he left behind a "legend of heaven"!
This is quite good fic. usually I dont read naruto fic but when I saw sky curtain exposure type, i got curious and checked it out. Readers may find having so many timelines at the same time be a bit jarring to read but once you lock in, it's very easy to keep up. Timelines are as follows from what I can recall: madra year 1 start 2nd hokage era 3rd hokage (younger) 4th hokage 3rd hokaga (post 4th death) 6-7 interlude with naruto the last movie. 7th hokage (pre boruto erasure, young boruto era) 7th hokage (older boruto / Sarada awakening MS) that should be about it. so you can understand it hopes from era to era constantly. overall give it a try.
