Ren Zhong always believed he was well-acquainted with the realm of Level Five Professionals.
He had researched extensively and understood that the core transformation from Fourth Level to Fifth Level is the integration of armor with the Sixth Sense, commonly known as combat intuition.
But he had possessed a Perfect Level Sixth Sense combat intuition for so long that he was no longer a typical Fourth Level.
He did not expect to undergo a transformation immediately after this upgrade.
According to his original plan, upon reaching Level Five, he would use the personalized and improved mental stimulant prepared in advance by Sun Miao, as well as a temporary colonization potion with weakened power but side effects controlled to an acceptable level.
