Actually, what Su Yu just said was merely speculation, without any evidence.
But Xiao Shengyin and the others had great faith in Su Yu. After all, the "big shot" spoke, and it was reasoned and evidenced, so they couldn't help but believe.
Only now did Xiao Shengyin and the other two finally understand what "inescapable fate" meant.
It turns out it was because they absorbed too much subspace energy, incurring a "debt" to the subspace.
Now the time has come, and with its chaotic nature, the subspace influences time and manipulates their fate.
It leads them to disaster and death, using life and soul to repay the debt they've incurred.
A short while ago, Xiao Shengyin and the others encountered Qiu Mo and heard Qiu Mo's theories about the Power of Time.
Originally, they were somewhat skeptical about Qiu Mo's theories.
No one expected that such terrifying power would come upon them so quickly.
This eerie doom was even more terrifying than Zhang Chenfeng's creations.
