"Understood!" Xia ruofei nodded heavily.
Soon, Guo Zhan contacted the other assault team members who were on standby through a secret phone and asked them to hurry to Sanshan University.
Then, the three of them prepared to open the manhole cover and enter the sewer.
Xia ruofei walked to the side of the manhole cover. Tian Feilong immediately came over and prepared to help the workers open the manhole cover. There were special tools. They hooked the holes on the manhole cover and lifted it up easily. Now that they did not have any tools, even if they were much stronger than ordinary people, it would not be easy to open the manhole without any force.
However, Xia ruofei waved his hand to indicate that there was no need.
He squatted down and used his fingers to grab a small gap on the edge of the manhole cover. He pushed it hard to the opposite side, making the gap as big as possible. Then, he put his fingers in and lifted the manhole cover with a light push.
