Yang Xiao mentioned sealing all the subway station entrances and making Xie Jun and his people rats underground, everyone inwardly gasped in shock, then burst into joy.
"Brilliant, that's truly brilliant!"
Xia Luo gave Yang Xiao a thumbs up.
"These subway tunnels were built tens of meters underground, reinforced with steel and concrete; they are extremely sturdy. Once we seal the entrances, it would be virtually impossible for them to climb out directly from the urban area. Even small explosives would hardly break through," Xiao Zhe explained.
"Heh, they can only escape through the subway tunnels to the suburban tunnel exits located dozens of kilometers away. Boss, should we also seal off the suburban tunnel exits?" Long Yongjun asked.
