Yan Monarch was not a Monster cultivator. Until he entered the Integration Period, he was a pure-blooded human.
When his cultivation level stepped into the Kalpa Passing Stage, he felt the frailty of the human race. Even if he had fully developed his Sword Body, it still wasn't enough to carry the force of the Immortal Sword Intention.
Even the incomplete ones wouldn't suffice.
Merging two Sword Intentions was easy, merging three was hard. After, every extra Sword Intention added made it even harder, until it became as difficult as ascending into heaven.
Yan Monarch attributed this to two things: comprehension and the inadequacy of his physical body.
If something was lacking, he would supplement it. There were a variety of ways to strengthen one's physique.
