[At the same time, you felt a subtle change in your Heavenly Thunder Physique; it was gradually strengthening...]
[By harnessing each bolt of thunder, your comprehension of the origin of thunder was also rapidly improving...]
[In the blink of an eye, the third bolt of thunder struck, you withstood it, gravely injured, on the verge of death...]
[The fourth bolt of thunder struck...]
[You died!]
[This simulation has ended!]
After the simulation ended, Su Xing sighed.
"It's a pity, still a bit short!"
"It seems that 128 Body-Protecting Sword Auras are still not enough to fend off the thunder's offensive..."
"If the Body-Protecting Sword Aura could advance further, it might withstand the thunder, allowing my comprehension of the origin of thunder to deepen, and the Heavenly Thunder Physique to advance further!"
In conclusion, Su Xing's direction was correct.
