Douluo Continent: My Martial Soul, the Dragon Abyss Sword, has become its scabbard.

The first fanfiction of Douluo Continent
In his previous life, Ding Quan, who had just entered society, unexpectedly arrived in Douluo Continent and awakened the (Dragon Abyss) Sword Martial Soul that he had forged in his previous life. However, when the Martial Soul awakened, the sword sheath merged into his body and became the Martial Soul's sword sheath.
It has become a special state of martial spirit true form.
The physical body can simultaneously acquire the characteristics gained by the martial soul absorbing the soul ring.
Ding Quan abandoned the path of pure attack and instead used the Five Elements as a foundation, supplemented by Yin and Yang, relying on nature, entrusting himself to time and space, and merging into the boundless.
