Ye Qing couldn't help but glance at the National Master again.
"What should we do? The door won't budge—huh? It's open! It's open!"
Of course, it opened. Xiao Hen had activated the secret mechanism.
He did it very carefully, making it appear as though Ya He had simply pried the iron door open to the untrained eye.
But Ye Qing knew very well that this iron door couldn't be pried open with tools.
The Crown Prince Changsun and Xiao Liulang thought locking it from the inside would prevent others from breaking in, but in fact, there was a main mechanism outside the iron door that could easily cause it to collapse instantly with a gentle pull.
This main mechanism was known only to Ye Qing and the National Master.
Ye Qing really wanted to ask his master why he didn't open the door.
But he ultimately asked nothing.
He was the master's disciple; he only needed to trust and follow his master.
