Rong Xingyu's face instantly changed.
He snapped his head up and looked at Rong Zishan. "Fourth Brother, no!"
Even though he didn't know the exact rules, Rong Xingyu could already guess that the "test" his fourth brother talked about was obviously letting the two of them race.
"It's too dangerous!" Rong Xingyu disagreed immediately.
He squeezed Ding Yixin's hand, looking worried and anxious.
He hoped Ding Yixin would refuse Rong Zishan.
It wasn't that Rong Xingyu was being biased, but his fourth brother was a professional racer and he was very familiar with this track.
So Rong Xingyu naturally worried more about Ding Yixin's safety.
If Dr. Ding lost to his fourth brother, that would be normal. But what if something happened during the race?
These two people, one was his family, the other was his lover and future family.
If anything happened to either of them, Rong Xingyu felt he would never be able to bear the consequences.
