I Have Become a Big Boss, and You Are Here to Persuade Me to Practice?

Zhang Yuan traveled to the world of cultivating immortals and became an ordinary disciple of the Yuhua Sect. As soon as he was bound to the system, he didn't expect that due to the resistance of the world's laws, the system would mutate and a state reversal would occur on him. Cultivation in progress: Cultivation level -1, -5, -7... During exercise: Physique -5, Strength -4, Mentality -3... During laziness: Cultivation +4, +3, +8... Staying up late: Strength +3, Constitution +5... … Zhang Yuan adhered to the idea that he would not reveal his strength until he was invincible, and practiced silently "lazily". Decades later, when the demon army joined forces to attack the Yuhua Gate and Zhang Yuan was about to step forward and annihilate the demons, his master, brothers and sisters advised him to practice hard and not become cannon fodder. Zhang Yuan: I have become a big boss, and you are here to persuade me to practice hard? This novel and its characters are purely fictitious.
