In Chu Yao's hand, he was holding a plain brown pill.

Her idea was indeed correct. There was no need for any spiritual power to catalyze it. She could just rub it with her hands.

Of course, this is not something that can be done casually.

The materials are crushed, ground, and sieved... the amount of water and medicinal materials need to be mixed in a certain ratio, and only after a strict procedure can such a pill be made.

This cannot be called alchemy by cultivators. It can only be said to be a relatively primitive method of making medicine. Even in the world of cultivation, it is the lowest level of alchemy method and can barely be called a compulsory course for entry.

But, you have to eat one bite at a time. At least you have cooked it, right?

Chu Yao placed the formed blood-moisturizing pill in his palm and sniffed it lightly, feeling that it was not a big problem.

Well... the next step is to test the results. I have to find someone to try the medicine.

While she was still thinking about her target, she heard her younger sister knocking on the door.

"What's wrong?" Chu Yao asked loudly through the door.

"Sister Chu, that guy surnamed Shen is here again!"

Hey, aren’t the people who are trying the medicine here?

"Let him go upstairs!"

It didn't take long for Chen Yu to arrive at Chu Yao's door, still wearing the familiar white suit.

As soon as he opened the door, he saw a dark creature rushing towards him with a knife.

"What is that?!" Shen Yu was horrified and took a big step back. He swung his left hand forward to block the hand holding the knife.

"Huh? I didn't expect you to be so good at fighting." Chu Yao put the knife back behind him with a little surprise.

That day, this man acted like a hero saving a damsel in distress, and she thought he had just hit Huang Long on the head by accident.

"Are you, Chu Xiaoye?" Chen Yu looked at her for a long time. To be honest, he did not recognize Chu Yao's appearance, but only judged her by her voice.

"Who else could it be if not me?" Chu Yao glared and turned back. "Come in, and be careful not to damage my tree."

"You...what are you doing?" Chen Yu was shocked by the flowers, plants and trees in the room before he even entered.

"If you have something to say, please say it. I'm busy and don't have time to deal with you." Chu Yao picked up a mortar and began to pound it. "If you really want to help me, try this for me."

Chu Yao pointed to the finished pill on the small table.

Chen Yu carefully looked for a place to stay among the flower pots and bronze and stone instruments on the ground, and then found a chair by the wall and sat down.

His eyes fell on a stove-like object placed in the middle of the floor, and he immediately became very interested in Chu Yao's "invention".

"Are you making a 'heavenly remedy'?"

"Are you talking about the classical prescriptions of your celestial beings? That's about right."

Chu Yao made a lot of preparations for refining the elixir, including looking up a lot of pharmaceutical-related information on the Internet, including records about "Tian Fang Yao".

Tianfang medicine is a traditional method of making medicine passed down from ancient times by the people of Tianren. It relies entirely on hand-polishing and the recipe is passed down orally. In modern times, this method of making medicine has gradually been eliminated. Laboratories and mechanical production have replaced the pharmacies of the past, and scientific and technological pharmaceutical production has become the mainstream today.

But Tianfang medicine still exists, and many of the antique-like instruments that Chu Yao bought came from these Tianfang medicine pharmacies that are still in business.

"Hmm..." Chen Yu touched his chin and couldn't help laughing again when he saw Chu Yao pounding medicine with a dark face.

"What are you laughing at? Are you here to laugh at me?"

"No, I think you'd better look in the mirror first."

Chu Yao took out her cell phone, turned on the camera function and took a quick look. Then she made a hand gesture and a large ball of water emerged from the soles of her feet, rolling up her body from bottom to top. Her whole body immediately became clean as new.

She threw the blackened ball of water out of the window.

"Super strong strength, controlling stone, condensing water droplets... You psychics have a lot of tricks up your sleeve. I wonder what other strange abilities you have? I want to learn them all."

Shen Yu said this with a smile, not knowing whether it was sincere or false.

"You can't learn it because you don't have the spiritual roots." Chu Yao's spiritual power surged throughout his body, and his wet clothes and hair dried immediately.

"Spiritual roots?"

Chu Yao paused, thinking that she had just said it casually, but it seemed as if she had revealed something extraordinary, so she stopped talking about it.

"Either you tell me what's going on, or help me test the medicine and stop sitting here and getting in the way."

She was extremely annoyed with this smiling tiger-like Shen Yu.

"I'm here to fulfill my promise, but you keep driving me away." Chen Yu picked up the pill and looked at it carefully. "How do I try it?"

"You cut it in your body and then you eat it."

"Okay, lend me the knife."

Chu Yao was stunned. She didn't expect the other party to agree so readily. So she threw the knife she had just held at him.

Chen Yu took the knife steadily, rolled up his sleeves and cut a shallow cut on his forearm.

"Eat now?"

"You can stab a few more times, just stab the artery."

Chen Yu stopped talking and silently put the pill into his mouth, chewed it and swallowed it.

The taste was bitter, a little spicy in the throat, and an indescribable discomfort in his mouth. As he swallowed the pill, he felt a surge of heat erupt in his stomach, rushing towards his injured forearm.

Shen Yu's expression became solemn. He saw that the wound on his hand stopped bleeding in less than half a minute and formed a thin layer of blood scab.

Under normal circumstances, it takes two to six minutes for the human body to heal and stop bleeding...

Shen Yu's mind raced as he looked towards Chu Yao who was also observing his injuries.

Just based on this elixir, he knew he had made the right "choice".

"Well, it seems there is no problem, it's just that the speed is a bit slow... Are you feeling unwell anywhere?" Chu Yao didn't care about his body, but only cared about the effect of the medicine.

Is this still slow? Shen Yu was shocked, but he concealed it well.

"No, it's just a little unpalatable... What's the name of this medicine?"

"Blood-moistening pill."

It's just an ordinary pill, there's no need for her to hide it.

"If this thing can be mass-produced, it will be a cash cow on Lingyuan Star." Chen Yu's mind was also focused on the Blood-Moisturizing Pill, and he even forgot the purpose of this trip.

"It's not that easy. There is a material that is very expensive, and it is still unknown whether it can be produced in large quantities." Chu Yao had obviously considered this matter, or rather, this was her goal.

"It's a bit troublesome if you can only make it by hand. Maybe you can go for the high-end route."

An intriguing look appeared on Chu Yao's face. This Chen Yu was actually trying to help her find a solution.

"What's the high-end route? Tell me about it."

"This medicine that can quickly stop bleeding seems a bit useless compared to the various medical methods in the hospital, but it is perfect for emergencies." Shen Yu showed his rigorous attitude at work.

"Mercenaries, assassins, and gang members like you are all constantly involved in bloody fights, so this is perfect for you. If we can establish a connection with such an organization and provide them with this Blood-Moistening Pill, the effect will surely be very good."
