Like a divine thunderbolt that could traverse virtual space, crossing through vacuum and space.
In an instant, it spans the void.
Of course, this requires a high realm to accomplish.
Li Xuan, with his current strength, naturally couldn't cross the void and space.
Nevertheless, when used, it was more swiftly and domineering than Xu Yan's Heavenly Lightning Flash, and exuded more of the divinity of thunder than Meng Chong's Furious Thunder.
"Such a good disciple! I, your teacher, am invincible mainly because of you all!"
Li Xuan was immensely excited.
In his high spirits, he conjured a true Qi resembling a tiny lightning bolt and tossed it into Shi'er's body, aiding Shi'er to hurry his internal cultivation.
As for the possibility of causing undesired rapid growth in Shi'er, that was not an issue; given Shi'er's innate talent, there was no risk of undermining his foundation.
