"Knock, knock, knock."
Lin Zhong, who was griping about Principal Ge Yunsong in his office, heard the knocking and then the voice of his dedicated secretary rose, "Commander Lin, there's been a bit of an issue with Captain Chu Feng."
Lin Zhong and Ge Yunsong, appearing in the holographic image, were both startled. Lin Zhong immediately said, "Come in! What happened?"
Secretary Wang pushed the door open and said, "Unregistered spatial fluctuations were detected on Captain Chu Feng. He explained that he has transformed his dantian into a Grotto Heaven and requests verification from Principal Ge Yunsong of Yan Capital University."
Lin Zhong was astonished and looked at Ge Yunsong on the information terminal, "Old Ge, what's going on?"
Ge Yunsong, stroking his beard, said with a smile, "A trifle, this old man can vouch for it, he indeed has evolved a Grotto Heaven."
Lin Zhong stared straight into his eyes and asked, "Grotto Heaven?"
"Grotto Heaven!"
"Explain?"
