Through his Byakugan, Yechen saw a Kirigakure warship drifting on the sea five kilometers away.
There was something unusual about this warship. Its surface seemed to be coated in ice crystals. From inside, the view outside was unobstructed, but anyone looking in from outside could only see the scenery beneath and behind the ship.
Clearly, this was a sophisticated camouflage technique that rendered the entire warship invisible by refracting light through ice crystals.
And all of this consumed almost no energy. An ordinary ninja would probably struggle to notice the ship even if they passed nearby.
Unfortunately for them, they had encountered Yechen.
Not only did he possess powerful mental strength, but his Byakugan was also far stronger than those of the Hyuga Clan.

"Lord Xueyu, our surprise attack failed."
Hearing this, Xueyu turned around and snapped,
"A bunch of useless fools!"
With that, he turned his palm upward and gathered energy. A snowy-white mirror resembling ice crystal floated above his palm.

"No matter how many times I see your masterful Ice Release ninjutsu, my lord, it never ceases to amaze me."
Xueyu thoroughly enjoyed the praise and chuckled.
"Of course. Ordinary ninjutsu can't compare with our Yuki Clan's secret techniques."
Indeed,
