The people who were most delighted among them were probably those from the Institute of Biological Sciences.

It can be said that I was ecstatic.

Because the dream of restoring the law has finally allowed people from the Institute of Biological Sciences to take blood samples and conduct research.

Unfortunately, Chen Cheng took Meng Yi to Bu Cai, the researcher of the murals, and wanted Meng Yi to see the murals there, but Meng Yi could not understand the words on the murals.

"Congratulations to Liusu for turning seven!" Lingxue took the lead, stepped on a stool, raised a glass of juice, and cheered loudly.

"Sister Lingxue, be careful of danger." Liusu said hurriedly.

In this birthday party, Liusu, as the protagonist, was the most uncomfortable.

It’s not that Liusu hates this atmosphere. On the contrary, she is very grateful to everyone. The reason she feels uncomfortable is that no one has ever held such a lively birthday party for her in all these years.

The birthday that Liusu had the deepest impression of before was the one she celebrated with her father. They had a small cake and a warm candle. Unfortunately, her father received an urgent task and left in a hurry just when they were halfway through the celebration.

Everyone raised their juice glasses and clinked them together, symbolizing the official start of the birthday party.

Seven candles were placed on the cake. Lin Yuhui's eyes flashed and the candles all started burning.

Wen Yuanyuan walked over and turned off the lights. Under everyone's gaze, Liusu awkwardly put her palms together, closed her eyes, and silently made her own little wish.

——I hope I can catch up with him soon.

And... ten years will be enough...

After making a wish, Liusu blew out the candle, and Wen Yuanyuan turned the light back on.

Amid the cheers and applause of the crowd, Liusu subconsciously glanced at Chen Cheng with a red face.

At the same time, Liusu accidentally glanced at Ye Xi who was looking at her with a playful expression, and Liusu quickly withdrew her gaze.

Because they were waiting for Chen Cheng, the birthday party started a little late. It was not until midnight that everyone had a great time, turned off the lights and went back to their rooms to sleep.

Chen Cheng went to the bathroom to take a shower. When he came out, he saw Liusu sitting on the sofa. He suddenly remembered something and quickly went back to the bathroom.

Liusu, who was sitting on the sofa, stretched out her hand and opened her mouth to say something, but she saw Shen Cheng running back to the bathroom. She pursed her lips and continued to wait for Shen Cheng.

After a moment, Shen Cheng walked out of the bathroom with a faint smile: "Liu Su, how do you feel?"

"I feel a little emotional." Liu Su sighed and said, "If I hadn't chosen to come to the Guangdian Cat Cafe with you, I probably wouldn't be where I am now."

"What does this look like now?" Chen Cheng put his hands behind his back and walked slowly towards Liusu, smiling and saying, "Liusu has always been Liusu. No matter what happens, Liusu will always be the same. This will never change in my heart."

Hearing this, Liusu's cheeks turned slightly red and she turned her head to the side.

At this moment, Chen Cheng also came behind Liusu with a faint smile on his face: "Come, Liusu, I'll give you a gift, close your eyes."

Smelling the fragrance of Shen Cheng, Liusu nodded, a smile on her lips, and closed her eyes.

Following a rustling sound, Liusu felt that Chen Cheng suddenly moved closer to her, and then she felt a chill on her neck.

If it were someone else, Liusu would probably subconsciously think that someone was trying to strangle her and would just throw her over the shoulder. Even Shao Silin was no exception.

However, the person standing behind her at this time was Chen Cheng. Liu Su was willing to maintain 100% trust in Chen Cheng.

"You can open your eyes now."

Hearing Shen Cheng's voice, Liusu opened her eyes, lowered her head, and saw a beautiful necklace appeared around her neck, which looked like twinkling stars in the moonlight.

There were two swans, back to back, and the place where they met looked like an unfinished heart, with only the heart's tip left.

Liusu's heart palpitated slightly.

She had heard Xueer mention this necklace not long ago.

Although Cher is not very interested in these jewels, she likes to explore the inner meaning of these objects.

The two swans facing each other can form a heart shape, which is the most straightforward love. The two swans facing each other, seemingly separated, but the place where their backs are facing each other and intertwined just forms a heart shape, which is... hidden love.

but……

Turning around and looking at the smug Shen Cheng, Liusu couldn't help but feel a little sorry.

Judging from this guy's personality, he probably has no idea what the necklace means. He just bought it because it looks nice, right?

It would be more appropriate for Liusu to give this kind of necklace to Chen Cheng instead of Chen Cheng giving it to Liusu.

But even so, Liusu raised her hands and picked up the two swans, feeling the faint warmth from the necklace, and her whole heart seemed to be filled with this small necklace.

"I like this necklace very much. Thank you, Shen Cheng. I will take good care of it."

"As long as you like it."

"By the way, Chen Cheng." Liu Su then remembered the important matter and turned to Chen Cheng and asked, "How did you handle today's mission?"

"We caught them all, but it's a pity that the leader escaped."

Chen Cheng rubbed his brows. After all, he had promised that he could handle it this time and let Liusu have a good birthday in the cat cafe. Otherwise, Liusu had planned to come with him.

"Don't worry about it. After all, they are a group of shadow mutants. Even if I go there, I probably won't be able to help." Liu Su had obviously found out about the situation of this mission during this period of time and comforted them.

"The most troublesome thing now is that we don't know where the leader has gone. He should have other hot weapons in his hands. He is simply a mobile time bomb." Shen Cheng crossed his arms and looked at the scenery outside the window, feeling a little worried.

Although that person could not cause any trouble on his own under the siege of the Institute of Biological Sciences, he was still afraid that he would make everything go to waste and then come to retaliate against him.

If the revenge was directed at Chen Cheng himself, it wouldn't matter, but if it was directed at Lin Yuhui and the others...

Chen Cheng clenched his fist silently: "In the next few days, I will go with the people from the Institute of Biological Sciences to search for the whereabouts of the leader. You and Lin Yuhui and the others should take care to protect yourselves..."

"You should stay at the cat cafe."

Liu Su shook her head and said, "After all, they're safest with you around. You guard the first floor, and Ye Xi guards the second. This will be safer. Besides, the Institute of Biological Sciences is conducting a blanket search, and you won't be able to help much."

"……you're right."

"Okay, don't worry too much. Let me tell you some good news."

Liusu smiled, dispelling the cloud of worry that had lingered in the living room. "We've heard from the Institute of Biological Sciences that the research and development of a drug to treat cancer is nearing completion, and the final product is a foregone conclusion."
