Digging tunnels right under the enemy's nose is definitely a very dangerous undertaking. It can't be done in just a day or two, and the risk of exposure is very high. However, Luo Zheng doesn't have a better choice, so he can only hope that it remains hidden under the radar and goes unnoticed. Nonetheless, Luo Zheng wasn't pinning all his hopes on just this method of tunnel excavation. After agreeing to Cao Xi's proposal, he glanced around and whispered, "We'll wait here until it's dark, running back now would risk exposure."
"That's fine, it's not long until it gets dark." Lan Xue said in a low voice, casting a glance at Cao Xi with a solemn expression and asked gravely, "Though the place you chose has some concealment, it's less than two kilometers from the base. There's a problem: the Dark Prison is underground. Do you know its exact location? Make sure you don't dig off course."
