Oil is a strategic reserve, and its value goes without saying.
Although Zhang Beixing hasn't had close contact with the petroleum department, with his status, no one would oppose him granting some extraction rights.
Moreover, this time, the Federation Clan helped Great Xia improve such important machinery.
With the help of the people from the Federation Clan, the work was swift; in less than 20 minutes, everything usable in the cave was moved out.
After everyone left, Zhang Beixing suddenly turned around to look at the cave in front, a cold smile forming on his lips.
Seeing the smile on Zhang Beixing's face, Leng Bing seemed to guess what was about to happen.
Just as Leng Bing was about to urge everyone to evacuate quickly, Zhang Beixing jumped up and punched directly above the cave.
Under Zhang Beixing's immense strength, the cave instantly collapsed, with shattered rocks blocking the entrance, as if the cave had never existed.
