Lin Chengfeng's face darkened as he stared at Lu Qingxuan coldly. In his eyes, Lu Qingxuan was lying to him.
"Lu Qingxuan, I advise you to surrender obediently. Otherwise, you won't have a good day today."
Chu Zhiguo looked at Lu Qingxuan eagerly, his eyes filled with greed. This was different from a few years ago. At that time, he was in high spirits, but now, he and his father were just two stray dogs.
He wished that Lin Chengfeng would seize the formula by force and abduct Lu Qingxuan. However, he knew that it was not up to him to make the decision.
"I don't know where you come from, but don't you understand? The formula was made public a long time ago. It has been patented for twenty years, but only three years have passed. According to federal law, during the patent period, no one is allowed to reproduce it. The focus was not on the formula, but on the patent. What good will it do you even if you come looking for me?" Lu Qingxuan said with a sneer.
