As long as Guan Yu is willing, he can instantly harness his power and directly enter another posture, shattering the ultimate inner energy barrier with divine force, rendering him able to slash any being under the heavens. Of course, whether his body can withstand it is another matter entirely.
This is also why Guan Yu's strength was not as fearsome when he withdrew from that previous state. As for the time he fought Sun Ce, Guan Yu truly didn't intend to kill him. He said he wanted to take down Sun Ce, but there was always a thought of capturing him alive.
After all, when looking at the world map, Sun Ce, who was just over twenty, appeared to Guan Yu as a genius, a true treasure of the Han Empire.
Incidentally, after Guan Yu gazed upon the world, understood the significance of the Empire, and fully stabilized his breakthrough posture, he actually regretted slashing Yann Liang.
