After traveling through time, my blood became a panacea

One day, Xu Feng was checking the growth of the herbs in the medicine field when Li Nianshuang suddenly ran over from the foot of the mountain and said to Xu Feng in an extremely urgent tone, "Master, it's bad. The mute sister's brother was stabbed by a wild boar's tusk and is bleeding a lot. Please go and have a look!"

Upon hearing this, Xu Feng knew the situation was urgent, so he hurried back to the house to get out the medicine box, called Xiao Hei, and quickly followed Li Nianshuang to the scene!

The dumb girl is the mute little mountain girl whom Li Nianshuang helped in the past. It is not known whether she and her brother were expelled from the mountain tribe or left on their own initiative. In short, like Xu Feng, the two of them live in a cave on a low mountain not far from Xiaogou Village!

Li Nianshuang felt sorry for the little girl and often brought her some food. As a result, the two had a very good relationship. Li Nianshuang never forgot about her when playing. As a result, the children in Xiaogou Village gradually accepted this little mountain girl! At least they no longer discriminated against and feared her!

I heard that the mute girl's brother was about the same age as Jian Yidao Er, but he was a mountain dweller after all, a natural hunter, and his hunting skills were quite impressive. Even the experienced hunters in Xiaogou Village were amazed! A half-grown child, his harvest was not much less than theirs!

It was thanks to his hunting and fishing that the two brothers and sisters did not have to starve and could barely make a living!

These are the information revealed by Li Nianshuang during his usual communication with Xu Feng.

Before reaching the entrance of the cave where the mute brother and sister lived, there was a clear trail of blood leading all the way to the cave. Looking at the amount of blood, and considering that the other party was just a half-grown child, Xu Feng felt something was wrong!

Rushing straight into the cave, Xu Feng found that the furnishings inside were simple. Apart from the necessary necessities such as beds, tables and stools, he only saw a big pot and two vats, one large and one small.

At this time, the mute girl's brother fell down with his back against the stone wall, covered in blood and fell into a coma. Next to him was the small vat. The mute girl's face was full of tears. She tried to press the wound on her brother's chest with her hand to stop the blood from flowing out.

Xu Feng hurried forward. When the mute girl saw him, she immediately babbled and called out to him. It was obvious that she was begging Xu Feng to save her brother.

Although he felt that the possibility of saving her was slim, Xu Feng immediately checked her injuries and felt the pulse of the mute girl's brother!

"Huh?" Xu Feng was surprised. Although the other party's pulse was weak, it was very stable. It seemed that the injury had been stabilized and relieved! How could this be? With so much blood, not to mention a half-grown child, even an adult would be in danger, and the blood was not dry, which proved that it happened not long ago. How could the injury be controlled so quickly?

After Xu Feng's repeated comfort and request, the mute girl carefully let go of her hands that were pressing on her brother's wound. Xu Feng carefully lifted up the other's blood-soaked clothes, revealing the wound!

Sure enough, only a small amount of blood was flowing out of the bloody wound. The boar tusk had almost pierced through the heart. With such an injury, an ordinary person would never be able to survive! What was going on?

Even without Xu Feng, the mute sister's brother's injury was saved, and the rest was to slowly recover. With Xu Feng, applying some medicine would only make the wound heal faster and the recovery time shorter!

After sprinkling the wound with powder to accelerate healing and bandaging it carefully, Xu Feng carried him to the bed and told the mute girl that her brother was fine and just needed to rest for a while!

The mute girl thanked him profusely and even knelt down. Xu Feng quickly stopped her, and then the mute girl stayed by her brother's bedside, not leaving his side. She wiped her tears from time to time when she saw her brother's condition. Li Nianshuang also stayed by her side.

Xu Feng was thinking about the abnormality of the other person's body! How did he do it? Xu Feng observed the inside of the cave and found that there seemed to be a few small insects twisting on the ground where the dumb sister's brother fainted. He squatted down and found that the small insects were black and a bit like tadpoles, but they were bigger and their bodies were flat.

Xu Feng suddenly had an idea and his eyes fell on the small tank next to him. Half of the tank was filled with water, and there seemed to be something swimming in the dark bottom! Xu Feng looked carefully and found that the thing swimming in the tank was the insect that he had just discovered twisting on the ground!

So, after the dumb sister's brother was severely injured by the wild boar, he immediately dragged his seriously injured body back to the cave and relied on these insects to save his life? Thinking of the traces left at the corners of the other party's mouth, did he eat them directly?

Xu Feng felt a little disgusted, but he also found that the insects seemed to be useful, so he secretly fished a few of them out of the tank and put them into an empty medicine bottle. After that, he told Li Nianshuang and took Xiao Hei back home!

After returning home, Xu Feng immediately took out a bowl and poured out the worms and water from the medicine bottle! The three worms immediately swam happily. The white bottom of the bowl made the appearance of the worms clear!

The wide, flat shell seemed to occupy the entire body, like armor, and behind it was a thin, long tail like a tadpole. Somehow, Xu Feng felt that this insect looked familiar, as if he had seen it before. Of course, it was not in this world, but on Blue Star.

After staring at these insects and thinking hard for a long time, Xu Feng finally remembered. This thing is called horseshoe crab, which is called a living fossil on Blue Star. It is said that it appeared on Blue Star hundreds of millions of years ago and has not changed much. It is a living specimen of Devonian creatures. In particular, its blood is still blue!

It is said that the blue blood of horseshoe crabs is an important bacterial identification material in the field of human medicine, and its value is comparable to gold. This has also caused the survival of horseshoe crabs to take a sharp turn for the worse. This species that has survived on the blue planet for billions of years is becoming less and less due to human demand for its blue blood.

In this spiritual world, there actually appeared a creature that could be called a living fossil on the Blue Planet! Xu Feng's intuition told him that this thing must be very useful!

I wanted to find someone to help me, but unfortunately, my two disciples Jianyi and Daoer were now focused on training and trying to comprehend the meaning of boxing. Except for eating and sleeping, they basically ran into the mountains, and I couldn't find anyone even if I wanted to!

When night fell and Li Nianshuang came back, Xu Feng showed her the horseshoe crab and asked her to ask the children in Xiaogou Village tomorrow to see if anyone knew where to find this kind of insect!

He didn't say much to Li Nianshuang, only saying that this kind of insect can be used as medicine and he wanted to catch some. Li Nianshuang naturally agreed.

The next day, Xu Feng asked her to take a horseshoe crab away so that the children in Xiaogou Village could identify it. The children in these mountain villages usually had no entertainment, so they went up the mountains and went down the water, and they were very wild. They had already figured out the area around the village. As long as there was one near Xiaogou Village, someone would have seen it!

Sure enough, in the evening Li Nianshuang brought back dozens of horseshoe crabs and said that these insects were found in a creek one mile west of Xiaogou Village, but there were not too many of them. She and a few friends worked for a long time to catch them.

Xu Feng was overjoyed and praised Li Nianshuang a few words, then raised all the horseshoe crabs in a big basin!
