"I need to test how effective my medicine is, so I have to find people from the mermaids to calculate the time when the wound heals."

"Okay!" Yi Xin agreed immediately and took the dagger without hesitation.

Grandma Divine Fish immediately wanted to stop it. Yi Xin is the princess of the mermaid clan and the last hope of the mermaid clan. How could she hurt Yi Xin?

Su Qingya needs someone to do the experiment, so she can do it!

However, before the words of Grandma Shenyu stopped him, Yi Xin had already cut his finger with a dagger without hesitation.

The bright red blood suddenly flowed out, and Yi frowned in pain, but there was no sound.

Su Qingya looked at Yi Xin and said, "I want to see the normal healing level."

"Um."

Yi Xin nodded and also stared at the wound on her hand.

She cut her very hard and the wound was very deep, but even so, the blood gushing out of the wound was rapidly decreasing, and Yi Xin's wound healed with a visible degree of naked eyes.

Su Qingya calculated the time in her mind, and it took only about a minute to cut her finger to healing intact.

Before, she just heard Grandma Shenyu tell Yi Xin that the mermaid tribe has the ability to heal itself, and it was not until now that Su Qingya saw it with her own eyes.

Looking at Yi Xin's intact fingers, Su Qingya had to sigh again that the physical fitness of the mermaid clan was really great.

Su Qingya looked at Yi Xin and said again: "I will get another cut. I will apply medicine to you this time."

"Yeah." Yi Xin nodded, holding the dagger without hesitation and stabbing his finger again.

However, before the dagger fell, Grandma Shenyu grabbed Yi Xin's wrist.

Even if the wounds of the mermaid tribe can heal themselves, seeing Yi Xin hurt herself like this, Grandma Shenyu couldn't help feeling distressed.

"Old son is also a member of the Mermaid tribe, let Lao son come."

She looked at Su Qingya, her eyes were firm and earnest. As she spoke, she reached out to take the dagger in Yi Xin's hand, but Yi Xin held it tightly and did not let go.

"Grandma Shenyu, I'm fine. The age difference between me and Bai Xi is not big, so it's more valuable to ask me to do the experiment. And the last time I cut my finger, so I'll cut it this time, so that the most obvious change can be seen after applying the medicine."

"If it were you now, not to mention that your age is too different from Bai Xi, in order to ensure the accuracy of the experiment, you have to cut yourself twice. Even if you can tolerate the pain, wouldn't the pain I just suffered in vain?"

Yi Xin persuaded Grandma Shenyu, and Su Qingya nodded repeatedly, admiring Yi Xin's intelligence a little more.

"That's right, Yi Xin is right, Grandma Divine Fish, I know you feel sorry for Yi Xin, but isn't Yi Xin doing now to protect the entire mermaid clan?"

Grandma Shenyu sighed and silently let go of her hand.

Yi Xin took a deep breath and armed her fingers again without hesitation.

Blood gushed out, and Su Qingya, who had already been prepared, immediately sprinkled the hemostatic powder on Yi Xin's fingers.

In an instant, something magical happened.
