Su Yu knew he absolutely couldn't let the King's plan succeed, otherwise things would get troublesome.
This Power of Pain conjured by the King is almost a nemesis for all mechanical lifeforms and Mechanics.
Imagine, Su Yu creates a mechanical army and battles the King; if the King's power is unleashed, Su Yu's mechanical army would be plunged into unbearable pain, as if falling into hell, unable to even stand, losing all combat effectiveness. How could they fight then?
Su Yu even suspected that not even Data Life would escape unscathed.
If the King succeeded, he would probably immediately gain the power to break through this Manifestation Space and escape.
Even if the King didn't advance to the Fifth Rank because of this, he might still match all the Mechanical Creations on the entire planet.
Including those creations of Zhang Chenfeng in orbit!
If Zhang Chenfeng's creations were controlled by the King's Power of Pain, the planet would be doomed.
