After cutting open and drifting away, Zheng Ren did not continue to open the pulmonary artery when he reached the inner membrane of the blood vessel. Instead, he prepared to start drifting along the inner membrane of the blood vessel.
"Old he, microscope." Zheng Ren said in a deep voice.
Old he quickly put the microscope on Zheng Ren's head.
For this part, he had to start the microsurgery. If the tumor could be removed along the inner membrane of the blood vessel, the surgery would be a success.
Otherwise ... They could only replace artificial pulmonary artery.
This was also an option. If Zhao Yunlong or Su Yun were to choose, they would choose to replace the blood vessels instead of wearing a microscope and letting the blood vessels wander.
The advantage of direct blood vessel replacement was that the operation was relatively simpler.
