When they arrived at the entrance of the secret base, the mechanical gate was completely sealed. Although a small peephole remained, it was impossible for any ordinary person to force their way in from the outside.
Prince of Shicheng Hua Tianxiong could certainly have breached the base from the outside; after all, his physical strength had already reached over 1.2 million catties of force. If he had attacked with all his might, the secret gate would not have withstood a sustained assault. However, doing so would have alerted those inside, prompting them to activate further defensive mechanisms.
The Prince of Yan was a ruthless man. As long as he could lure attackers into the tunnels, he was willing to sacrifice everyone within the base to ensure the intruders were eliminated.
