Chapter 573: Can't I change the rules that I set?

Everyone turned around.

They saw a man standing at the restaurant's entrance, suitcase in hand.

"Third Brother is back," Xi Yanbo called out gently.

Xi Yanbo and Xi Yankai had been enjoying the show since the beginning.

The Xi residence was often cold and deserted, so such a lively scene was quite rare.

Xia Yangyang was slightly taken aback by the man's presence.

Back in the research lab, she had already begun to suspect.

The lab must belong to Gu Zhaohan.

In this world, no one cared about Xia Ye's condition more than Gu Zhaohan did.

And also, those notes in the files.

Xia Yangyang recognized them at a glance.

Xia Yangyang almost forgot.

Gu Zhaohan had returned to the Xi family four years ago.

However, he was never willing to change his surname.

It was said that Xi Jiachen thought highly of him and had been trying to convince him to work for the company over the past four years.

But Gu Zhaohan insisted on studying medicine abroad.
