Qin Su awakening Observation Haki under Doctor Tanchi's pressure was indeed a pleasant surprise.
But as Doflamingo had said, that alone was not enough to secure victory.
The question was, what could he do?
Alchemy did counter creatures like the Sea Monk, but the problem was that he needed to touch it with his hands.
However, Doctor Tanchi had long seen through that and countered him with high-pressure water streams.
Especially the "Water Release: Water Severing Wave" taught to him by the Second Hokage.
Qin Su did not dare block it with his hands, and even the ice walls he created could not withstand it.
Most crucially, these water blades were terrifyingly fast and incredibly dense.
They formed an extremely ferocious barrage across the arena.
Qin Su and Susanoo were barely holding on through their cooperation, leaving the entire audience tense.
No one had expected Doctor Tanchi to be so powerful once he got serious.
"Qin Su!"
While struggling to swing his steel club against the Water Severing Waves, Susanoo shouted his master's name behind him.
"Should we use that?"
Qin Su hesitated for a moment, then immediately gritted his teeth and made his decision. He knew this was no time to waver.
However, in that instant of hesitation—
Susanoo's steel club was knocked away by a water blade, and another water blade shattered his right arm.
"Susanoo—"
Qin Su's eyes went red. He slammed both palms heavily onto the ground, pouring far more mental power into it than before.
In an instant, accompanied by rumbling tremors—
One ice wall after another, seven or eight meters tall, rose from the ground.
They surged layer by layer toward Doctor Tanchi with overwhelming force.
Although the Sea Monk continued firing Water Severing Waves, the scale of these ice walls was too great
