Lv Danyang asked.

"Terrorism?"

Ye Fei shook his head, though he did not want to admit, now Liu Han was really a terrorist.

"Before Liu Han caused other damage, Ye Fei, I hope you can help us catch him! For the central leader and for yourself."

Lv danyang sat down again, still watched Ye Fei.

Ye Fei hung his head and thought for about ten minutes before he opened his mouth, "Sorry, I can't do that!"

"What! You said you couldn't do that!"

Lv Danyang became furious and said, "Why can't you do that? Liu Han is a traitor, you should help us catch him, why can't you do that? If you won't promise, then I can't let you out! You will be killed by the secretary Yuan sooner or later! Do you want to die for Liu Han?"

"Now Liu Han is a traitor and betrays his country now, but he saved my life and was my benefactor. I will not betray my benefactor."

Ye Fei said slowly and firmly, "Sorry, I can't promise you!"

"You are really stubborn!"

Lv Danyang was very angry, and he threw the cigarette to the ground, walked around in the interrogation room.

"Ye Fei, I'll give you five more minutes, you think about it!"

Lv Danyang said.

"I have thought well, and I will not betray Liu Han."

Ye Fei said at once.

"You..."

Lv Danyang pointed at Ye Fei's nose, and did not know what to say.

After a long while, Lv Danyang sat back to the chair, looked out the window and muttered, "Central leader, you win! You are right. Ye Fei... He's a really hopeless idiot."

Lv Danyang stand up again, walked to Ye Fei's side, said, "Ye Fei, in fact, the central leader has known you will not betray Liu Han. He didn't see the wrong person. Now, Let me give you the real task of the central leader."

Originally Ye Fei was already desperate, when he heard the words of Lv Danyang, he immediately saluted and said, "Yes, sir."

"The central leader ordered you to find Ye Tianchen as soon as possible! This is your chance to make amends!"

Lv Danyang seriously said.

"Ye Tianchen, my grandpa?"

Ye Fei was stunned, "My task is to find my grandpa, what's going on, I don't understand."

"I'll explain it to you! Sit down and we'll talk about that."

Lv Danyang presses Ye Fei's shoulder and asked him to sit down.

"Ye Fei, You should know, now the urgent matter of MSS is the type JF1 medicament. In fact, because last time you captured colonel Jack, and provided a sample. We have perfectly reproduced this new type of stimulant."

Lv Danyang slightly frowned, "The function of this medicament is very powerful, if we can use it in the army, then our army's fighting power will be doubled. Unfortunately, this medicament now has a lot of side effects! It not only has a strong addiction, but also makes people lose their sanity, become a homicidal maniac. It's not a stimulant, it's a poison!"

"What does that have to do with my grandpa?"

Ye Fei shook his head.

"your grandpa Ye Tianchen is a very famous highly skilled doctor, and our experts agree that if one person can study the method of releasing the type JF1 medicament, then it must be your grandpa."

When Lv Danyang mentioned Ye Tianchen this name, he became very excited.

"Mr. Lv, don't scare me! My grandpa's medical skill is good, but it is only a doctor in the country! But this kind of research work, I think others must also be competent!"

Ye Fei shook his head, because he did not believe that.

"No! You say those words because you don't know your grandpa."

Lv Danyang rummaged about in his bag and took out an old magazine and handed it to Ye Fei.

This magazine was an English weekly, after Ye Fei looked at that, he was surprised. This magazine was the authoritative magazine in the world, many experts and professors wanted to publish an article in this magazine.

Opening the magazine, Ye Fei immediately saw a large black and white photo of his grandpa, Ye Tianchen, talking and laughing with a balding foreign scientist.

In the middle of the magazine was an article published by Ye Tianchen, Ye Fei had been living abroad for many years, so his English was quite good, but he could not understand some professional words.

"My grandpa is a medical expert?"

Ye Fei was shocked.

His grandpa, Ye Tianchen, was a legend.

He had many aliases and many professions.

He had made sensational cases of theft, and he also had treated many high officials and state leaders.

To tell the truth, Ye Fei did not know his grandpa, only thought he was an old man with bad temper.

It did not occur to Ye Fei that his grandpa had been a renowned medical expert in the world, who was in charge of the research on stimulant.

"These things are state secrets and should not be shown to you, but you are Ye Tianchen's grandson, so I will tell you."

Lv Danyang slowly said, "Before returning home, Ye Tianchen is a well-known medical expert in the United States. Then he returned home, but a part of his research data still was in the United States. Therefore, we doubt that the United States military use the research data to develop type JF1 medicament!"

After Lv Danyang gave such an explanation, Ye Fei completely understood.

Unfortunately, now Ye Tianchen was missing for more than ten years, even the country could not find him.

"If it's just looking for my grandpa, I promise you! Because, I also have been looking for him!"

Ye Fei nodded and agreed to Lv Danyang's request.
