I Planted Myself into the Secret Realm for a Hundred Thousand Years

During the battle between immortals and demons, Sword Immortal Lu Cheng was framed and died. Before his death, he planted a wisp of his spiritual thoughts into the secret realm of Taichu together with the seeds of the ancient trees of Taichu. One hundred thousand years later, Lu Cheng woke up and discovered: The broken sword that was planted at the beginning has now grown into an immortal sword; The drop of true dragon's blood that was originally planted has now grown into a dragon egg; A piece of colorful sky stone planted at the beginning has now grown into a colorful sky stone mine; The grain of pure Yang rice that was planted in the beginning is now everywhere in the Pure Yang Immortal Valley; The Sumeru ring that was originally planted has now grown into a small world inside.
