Fatal Shot - Chapter 8: Shameless Gunner

Within a quiet and majestic pavilion, Xuan Hao slowly opened his eyes bewildered, time passed and he had quietly come to terms with his situation. He had transmigrated into a fantasy world as an elder of the Flying Sword Sect.

He was even an expert at the Nascent Soul Realm, who had the power to easily destory an entire city with a wave of his hand.
Most importantly, he had a system, but it kept wanting him to train up disciples.

«What now! I already trained up a few Celestial Immortals, what more do you want out of me? Can’t you just give me some random cultivation method that magically allows my disciples to become immortals within a few weeks?»

[Have 4 disciples achieve godhood]

[Reward: Cultivation Increase of 1 major realm]

Chen An traveled to the world of cultivating immortals, and his cultivation talent was extremely poor. He was stuck in the third level of Qi refining for many years and could not make further progress.

Seeing that there is no hope of cultivating immortality, he chooses to return to ordinary life, and marries a wife to enjoy the ordinary happiness.

As a result, on the night of their marriage, they returned to the fairyland overnight.

It turned out that marrying a wife and enjoying ordinary pleasures was his way to become a fairy, and it could directly save him thousands of years of detours.
