Chương 230: Making Body Light but Not Old

Some licorice roots could make the human body light and younger, but Wang Yao couldn't get those licorice roots at the moment.

"Thank you," said Guo Sirou after keeping silent for a long while.

"Please don't thank me. I couldn't help you," said Wang Yao.

After staying in the club for a while, Wang Yao went back to the cottage and found He Qisheng had been waiting for him outside.

"Hello, Dr. Wang, you are back," said He Qisheng.

"Please come in," said Wang Yao. "We are in Beijing now; why do you still bring gifts?"

"It's not nice to come here with bare hands," said He Qisheng with a smile.

The two of them had known each other for quite a long time and had kept in contact regularly, so they both of them felt comfortable talking with each other.

"How can I help you?" asked Wang Yao as he noticed He Qisheng was hesitating.

"I need a favor," said He Qisheng.

"What is it?" asked Wang Yao.
