"Congratulations, Angie. I'm honored to be the youngest doctoral graduate of Imperial College." After half an hour of deliberation, the six professors unanimously passed the reply.

"Thank you." Ye Xin got up and went forward to shake hands with the professor of defense one by one to thank him.

"Angie, do you want to stay and be a professor?"

"Sorry, I'm going to return home now, but I'm willing to help if I really need me one day." Ye Xin said gratefully. Although she didn't hold much expectation and didn't have a leisurely study time, she was really happy.

Out of the meeting room, Simon was happier than Ye Xin. For more than three hours, Simon never left. The corridor was full of people, partly because of Ye Xin, but more because of Simon.

Simon is a visiting professor at Imperial College, but for more than two years, Simon has only taught by video and never returned.

"Congratulations."

"Simon, I thought you would give me a certificate in forensic medicine?"

"There's no point in issuing that certificate here, isn't it? It should be awarded to you by your alma mater. " Simon read Ye Xin's information. He thought Ye Xin couldn't bear hardships. It seems that he was wrong. Ye Xin's only disadvantage is that she sleeps a little. There are many wars. She will rest for eight hours. However, Ye Xin is very dedicated.

Over the past two years, although he spent every day in the smell of blood, Ye Xin seemed not interested except Lin Shengyi's blood, so he had to rely on rest to supplement his physical strength.

Of course, eight hours of rest is not always the case. She always needs her own time.

"Indeed, Simon, I'm going home."

Simon was not surprised by Ye Xin's words. Hansen stayed abroad for two years and was strongly requested by the school. At the beginning of the year, he also returned to the capital.

"When."

"Tomorrow."

"If I have something to do tomorrow, I won't send you. I wish you a safe journey. If necessary, please contact me at any time." Although Simon is Ye Xin's mentor, their relationship is more like friends.

In the darkness of the battlefield, Simon never hid Ye Xin.

The only thing Simon can hide from Ye Xin is why he chose to be a doctor without borders. She only asked Simon about this. Simon was silent and her eyes were sad, which she still remembered. She never mentioned it again.

She happened to see the pendant on Simon's neck, which is very valuable. Simon's family background should be not simple, just because she is a friend. Ye Xin has never investigated Simon.

"OK, here you are." Ye Xin took out a wolf tooth pendant from his pocket (actually in the space) and handed it to Simon.

"Thank you." This is a gift from a small African tribe to Ye Xin, which means peace in life and to the most precious friend.

After parting, Ye Xin returned to the apartment. A few days ago, Ye Xin was busy writing papers in the library and Simon's office. She had no leisure time at all. Now she was finally free and could have a good rest. After more than two years, the apartment was still spotless. Ye Xin opened the wardrobe, which was filled with the most popular clothes of the year, all of which were her favorite styles.

Ye Xin picked up her cell phone and dialed Joey's number.

"Little angel, you're back in London. Why did you think of calling me?" Before Ye Xin spoke, Joey immediately snapped.

"Hello, Joey."

"We are in country m. We have been busy recently. The boss is in a meeting. Do you need me to call him?" Joey almost contacted her in the past two years. After Lin Shengyi disappeared for a year and a half, her whereabouts became more mysterious. The only thing she knew was that the mysterious organization would send a batch of clean water and food every month. He was the only one who could do so in the world.
