Then Lu Yuan found Qiao Ke and told him about the situation at the higher-ups. When Qiao Ke heard that there were seven switches in total, and that if even one was wrong, they would not be able to leave, he immediately felt a surge of tension.

"This might be the biggest challenge I've ever faced, and I never expected it to be this!"

"How's it going? Are you confident? Do you need any help?"

After a moment of contemplation, Jock nodded slightly: "I need help. I might not be able to complete this task by myself. By the way, should we open the seven protective plates one by one, or all at once?"

After thinking for a moment, Lu Yuan said, "Open it layer by layer!"

"Okay, then there's no problem. I'm afraid it's a seven-chain operation, which might take a lot of effort to set up. If one step goes wrong, all the steps could go wrong. By the way, can I see Lin Qi? I want to ask him something!"

Lu Yuan nodded: "Okay, feel free to ask any questions, but we absolutely cannot make any mistakes, otherwise we will be trapped in this place forever!"

Of course, Jock knew that this matter was of great importance, and he dared not take it lightly. So he quickly followed Lu Yuan to the hospital, found Lin Qi again, and asked him some questions about opening the ceiling. After that, Jock confirmed that it was opened layer by layer, and the method used for each layer was the same, only the password was different, and it required seven people to open it together.

"Breaking this military-grade combination lock is a huge challenge for me. I've never cracked such a difficult lock before. I don't know what the person who designed this was thinking. It's outrageous!"

Jock gritted his teeth and slammed his fist on the table. Actually, he really enjoyed this kind of challenge, but this matter concerned the lives of millions of people.

So he couldn't help but be nervous, because if he made a mistake, everyone would be trapped in this place. He felt that the burden on his shoulders had become much heavier.
