The smiles on Fu Yuan and Li Sicheng's faces faded in one second.

"What's wrong? What happened?" Fu Yuan quickly walked forward, but even her steps were in a mess, and she was panicked to the naked eye.

"Be careful!" Li Sicheng hurriedly supported her, afraid that she would fall.

Bart's face looked ugly. He wanted to explain everything clearly in one breath, but he really didn't know what to say at this time.

"Tina, you...you should come with me! Professor Federman is already dealing with it, but...but I feel..." Bart stuttered, and finally stopped talking and led the way directly in front. Because he was anxious, he was walking and running.

Fu Yuan and Li Sicheng's breathing tightened because of Bart's words.

Especially Fu Yuan, this is definitely the thing she doesn't want to hear the least. She... worked hard for so many days, and she was excited to tell everyone yesterday that she had succeeded, but at this moment... she ruthlessly poured her a large pot of cold water.

She just felt cold, and the coldness made her feel bitter.

She was not afraid of starting over, nor was she worried about failure, but what should her child do? What should An An do? He can't wait any longer!

Li Sicheng lowered his eyes and glanced at Fu Yuan's pale face, and his heart skipped a beat, "Wife, don't be anxious first, the professor is already remedy, I will definitely not."

But Li Sicheng's comfort no longer had any effect at this moment. Fu Yuan's heart turned into a mess with the laboratory that gradually appeared in front of him.

Li Zian, who was held by Li Sicheng, had a very white face.

Although he is still young, he understands all the things the adults said just now, so... he...

No! No! No!

Mommy said that she would definitely come up with a solution!

His mommy is the mommy who loves him the most in the world, and his mommy is the best mommy in the world. Mommy said that she will not let him lose his life.

So, he must be stronger!

Be a little stronger.

Finally, they arrived at the laboratory.

Because of sterility, Li Sicheng and Li Zian were stopped outside, and Bart was also standing outside because he couldn't help at this time.

Li Sicheng held his son and observed his son's emotions carefully with deep eyes.

Seeing this, Li Zian said, "Dad, I'm fine! I'm not afraid. I believe that Mommy will succeed, Mommy will succeed."

Li Sicheng breathed a sigh of relief when his son said, and he nodded gently, "Well, I believe in your mommy, too."

Bart looked anxiously and focused at the situation in the laboratory, watching Fu Yuan put on a sterile suit and operated on the laboratory bench with Professor Federman, and a look of annoyance appeared on his face.

After taking care of his son's emotions, Li Sicheng turned his attention to him, "What the hell is going on? Didn't everything go smoothly yesterday? Which link is wrong?"

The implication is that Li Sicheng is questioning Bart.

An An’s affairs were done by Professor Fu Yuan and Professor Federman. Before yesterday, everything was planned, and the two of them left yesterday. The matters in the laboratory were then handed over to Bart. Now that something happened, the problem was naturally with Bart.

Bart felt a chill on his back, and then closed his eyes hard.

Of course, he understood what Li Sicheng said. He wanted to explain that this matter had nothing to do with him. He did not do anything, and even adhered to the experimental requirements and compared the potion. But something happened, which left him speechless.

"Bart!" Li Sicheng's voice sank a little.

Bart had to bite the bullet and speak, "Mr. Li, this matter is too sudden. I...I haven't figured out which link is wrong."

"Don't you know?" Li Sicheng was not as easy to talk to as Fu Yuan. "You are the only one in charge of the laboratory. You told me that you don't know? Is this what you should say?"

The cold and hard sound is like a knife blade.

Bart frowned, his face full of disgrace, "Mr. Li... I have dereliction of duty, but please believe me. Since I promised to follow you, I have no other thoughts. I love my profession and am more fortunate to be able to work with Professor Federman. I can guarantee it with my personality!"

"So, where is the problem?" Li Sicheng didn't want to hear what he said. He only cared about what was wrong.

Bart took a deep breath and said while thinking: "It was originally very smooth. After Professor Federman and Tina left, I was responsible for the preparation of today's experimental medicine. Moreover, I was in the laboratory almost all night, and all the raw materials had never left my sight. I was waiting for you to come today, but..."

"What happened?"

"Just half an hour ago." Bart looked in disbelief. "Half an hour ago, Professor Federman arrived at the laboratory first, and I told him that I had prepared the drug successfully. I really prepared it successfully. I tested it myself and there was no problem at all. Professor Federman also looked at my test data, but Professor Federman has always been cautious. Although he read my test data, he still felt that it was necessary to do some tests. This time, there was a problem."

Bart took a deep breath, as if he was still in the shock just now, "It's really strange. It was obvious that everything was normal in my hands before, but when Professor Federman tested, there was a qualitative change."

"So, if Professor Federman didn't do the test again, the potion would be used on my son now, right?" Li Sicheng felt something exploded in his heart.

Bart's face changed. After a few seconds of silence, he nodded heavily with his eyes closed.

Li Sicheng grinded his teeth hard, looking at Bart with anger, but the next moment he restrained this emotion.

If Bart said it true, then this matter was simply weird everywhere. He didn't know much about biological science, but because of An An, he also read a lot of information. At this moment, a word suddenly flashed through his mind.

Changes!

He frowned, "Bart, if your potion is not a problem, is it because there is something wrong with the sample tested? Has there been a change?"

Butter paused, and was obviously surprised to hear the word "mutation" from Li Sicheng's mouth, but the next moment, he shook his head.

"No, it's not the case!" He answered with great certainty, "The experimental samples are all sealed, and after they leave the body, the experimental samples do not have the possibility of mutation in a short period of time."

"That's the problem with the potion." Li Sicheng said again.

Bart shook his head, "This is even more impossible. I have been in the laboratory all the time. I personally match the potion. I never left my sight before Professor Federman came."

"No! It must be someone who has tampered with the medicine, and it is very clever." But at this time, Li Sicheng was extremely sure.

Bart was stunned!

This...how is this possible?
