However, towards the end everything seemed a bit rushed.

MC and ML knew each other over a thousand years ago. At that time, ML was MC's eldest disciple. MC had saved ML when ML was a child. Later, ML grew up and fell in love with MC. ML did not confess to MC but showed his love in thoughtful ways. MC ended up falling for ML and confessing to ML first.

However, MC was the Heavenly Ruler. He was the real Heavenly Ruler. He saw the common people suffering due to the invasion of demons. So he created a formation to protect the continent. The problem was that the formation needed a special formation eye. MC's body became the formation eye and he told ML to pretend to be the Heavenly Ruler after MC was gone.

MC's soul should've gradually dispersed after his body became the formation eye but ML was able to protect it by placing MC's soul into a sword to nourish it. MC's soul became like a toddler and had no memory but ML was happy that at least MC's soul was still by his side. Hundreds of years later, ML's cultivation level reached level 10 and he could ascend. He wasn't interested at first but later he heard a rumor that the Heavenly Realm had a method to allow a sword spirit to have a physical body.

But there was a problem during ML's tribulation. The lightning strikes were more ruthless than expected. ML wanted to let the sword containing MC's soul fall to safety but the sword unsheathed itself and took the lightning hit for ML instead. The sword shattered and ML could've ascended but ML chose to preserve MC's soul at the expense of his body. MC's soul entered the reincarnation cycle and ML's soul parasitized a cherry blossom tree on Kunlun Mountain. ML waited for years and years for MC to be reincarnated. Until MC was born as the young master of the Kunlun Sect.

In the end, they were able overcome a lot of obstacles to finally be together. ☺️
