Lin Zhen's attack was extremely tactical.
Xiao Se's arrogant declaration that he would only use twenty swords before entering the Holy Land demonstrated his strong self-confidence.
Moreover, Lin Zhen had just crossed swords with Xiao Se, gaining some understanding of his power. The other party's comments were reasonable; his first few swords were indeed hard to fend off, bearing the force of a thousand thunders.
If his opponent was weak, Xiao Se could kill with a single blow. If the opponent had some strength, he could easily fend off his weapon using his star power, and his sword, at its peak of power and speed, was truly hard to resist.
The first thing Lin Zhen had to do was to shatter Xiao Se's self-confidence.
Knowing full well that Tianhe Star Explosion wouldn't harm Xiao Se, Lin Zhen still used it, to make him eat his own words.
