Normal people could not stand not sleeping for the past few days. When his head touched the pillow, he fell asleep as if he had fainted.

When he woke up, it was already the next night.

Shao Feng felt as heavy as if his entire body was filled with lead. He desperately raised his arm and used all his strength to get out of bed. He washed his face and packed up before sitting in front of the experiment table Yu Xuan had prepared for him.

Medicine concoction, testing… He had not slept for an entire day, but there was no improvement. Every lab rat he fed had died, and the cause of death was heart failure.

Shao Feng only felt that he had been tortured inhumanly. This torture was not only physical, but also mental.

At the same time, his understanding of Yu Xuan’s viciousness deepened.

This woman seemed to be doing nothing, but she was the most vicious.

She did not torture any of them or do anything. Just by relying on their own desires and instincts, she could torture them until they were neither human nor ghost. There was no problem on the surface.

Now, she had thrown him to such a good place to concoct medicine. He ate and drank well every day. The bed was big and soft, but how could he be in the mood to eat and sleep?

If he made the slightest mistake, if there was even the slightest delay, his sweetheart would be completely dead.

Yu Xuan was best at catching others’ weaknesses and then using the most dignified method to make others pay the heaviest price!

At the thought of this, he was angry and anxious, his heart filled with despair.

Other than developing suitable drugs, he had no other choice.

After studying medicine for so long and saving lives for so many years, this was the first time he encountered such a test!

Even when he had to perform more than ten surgeries on the operating table, he had never been so mentally and physically exhausted.

His hands were trembling, but he tried his best to control them from trembling. This was because every second of trembling concerned his and Hu Wan’s lives!

In the blink of an eye, it was noon on the third day. A group of mice had already died. Shao Feng widened his eyes and did not dare to rest for a moment. He continued to weigh the medicine, add medicine, stir, test medicine, observe, and modify…

Finally, he realized that a white rat had been active for three to four hours and was still very lively. There were no signs of heartache.

He quickly tore off the label on the rat. On it was the ratio: three ml of amicillin, 1.2 ml of epirubicin…

Shao Feng desperately suppressed his trembling heart and shouted excitedly, “Come, come!”

“Doctor Shao, what’s wrong?” Xiao Sheng quickly walked in and asked.

“Find two monkeys. Hurry, I want to test the medicine!” Shao Feng quickly pulled Xiao Sheng back and shouted.

The lackeys were very efficient. Soon, they grabbed two monkeys that they had prepared in the basement.

Shao Feng matched a new medicine according to the ratio and stirred the medicine into the monkey’s food before handing it to the hungry monkey.

The two monkeys finished their food in no time. What followed was a long observation period. Shao Feng did not even dare to breathe loudly. If he took this medicine for more than three hours and the monkey did not have any heartache symptoms, then he would have succeeded!

As time passed, Shao Feng stared at the monkeys, not daring to take his eyes off them for a moment. Every time the monkeys stopped playing and wanted to rest, he would subconsciously chase them away to move.

It seemed like this was the only way to keep the monkey active, even though he knew that it was just a ruse.

Three hours was so long. Shao Feng counted every second and minute, beads of sweat appearing on his head.

If he did not succeed, Hu Wan might really not be able to last.

If Hu Wan could not hold on, his outcome would not be good either. If the plan failed, that demoness Yu Xuan would probably kill the two of them, which were worthless pieces. After all, this woman’s methods were here!

After an hour, the monkey was still alive and kicking. Shao Feng felt a little comforted.

Two hours later, the monkey fell asleep.

Shao Feng was shocked and quickly woke up the monkey. After the monkey woke up, it went to eat. It looked quite healthy.

He endured the last hour minute by minute and realized that the monkey’s condition had been very stable.

A wave of joy surged into his heart.

“Hurry, hurry up and tell your boss that the medicine is done!” Shao Feng walked out of the room trembling and said to his lackey guarding outside.

“Doctor Shao, you’ve worked hard!” Unexpectedly, Yu Xuan was already waiting outside. When she saw him, she immediately said, “I knew it. Doctor Shao is a talent in this industry. How could he fail?”
