With hundreds of water crystals collected, the coral insects still had no response. Ding Ning was ecstatic. Ha ha, it seems that the coral insects won't mind their own business.

Although he was afraid of the jellyfish, he was not afraid, but he was also afraid of the immeasurable coral. After all, the red flame emitted by this thing could melt the jellyfish's hard skin. It can be seen how terrible the temperature of the flame was. He didn't want to be turned into the nourishment of red coral by coral insects.

Frightened, he collected more than 100 pieces of water spirit crystals. Seeing that the coral insects did not respond, Ding Ning no longer had any scruples and wantonly began to collect and scrape water spirit crystals.

Just when he was in a happy mood to collect shuilingjing, suddenly, a strong life and death crisis made him creepy. He stood stiff on the spot and didn't dare to move. He was frightened and wanted to look at the "blood man" suddenly in front of him for fear of angering it.

There is more than one "blood man". There is a "blood man" in each red coral. Under Ding Ning's heavenly eyes, these "blood men" are all composed of coral insects.

I don't know if it's because I've never seen humans. These coral insects curiously simulate the shape of Ding Ning, form human "blood people", and imitate his actions to turn around, bend over and pick up

It looks very funny, but it makes Ding Ning's hands and feet cold, like falling into an ice cave.

He would rather face the jellyfish than the monster that can emit terrible heat.

Trembling, he took out a handful of Lingjing, cried, nodded and bowed and said, "give it back to you. Can't I do without it?"

Who knows, those "blood people" felt the Spirit Crystal breath in his hands, scared and retreated, and even the human shape could not be maintained.

Are they afraid of water crystal? No way.

Ding Ning looked at these "blood people" strangely, and even the human shape could not be maintained. With a "buzzing" sound like fleeing, a swarm of bees fled back to the red coral, and in a twinkling, peace was restored in the cave.

A crisp feeling came from his hands. Ding Ning found that he made a mistake in his hurry and took out a purple Lei Lingjing in a handful of water Lingjing.

Thinking of the fear of coral insects before, Ding Ning wanted to laugh wildly. It was really a mistake. Unexpectedly, the coral insect was afraid of Lei Lingjing. Great, ha ha ha!

With a drooling look in his eyes and a sinister smile, he approached a red coral about three meters high with Lei Lingjing.

With a buzzing sound, the coral insects in the red coral scattered and fled to live in other red corals, never daring to stay in the red coral again.

Sure enough, Ding Ning smiled, picked up the red coral and tried to break it into the mermaid space

However, he didn't break it. Ding Ning's chin almost fell off. NIMA, he has at least tens of thousands of kilograms of power now. He can't break a coral tree. Isn't that a ghost animal?

Ding Ning, who didn't believe in evil, turned red, his veins burst on his arm, roared "open", and even used his milk strength. As a result... He still didn't move.

"Especially, I don't believe it!"

Ding Ning took out the silver Taidao and cut it hard at the root of red coral.

The sound of "Dang" sent out the sound of gold and iron. Ding Ning's arm was numb, but the red coral didn't even appear.

Ding Ning was so stupid that he wanted to push back the coral insects and go back to make a fortune with a red coral. Unexpectedly, he even cut it continuously.

The hardness of the red coral is ridiculous, but Ding Ning doesn't find it difficult to understand that it is likely that it is all broken down and solidified again by the hard shell of the jellyfish.

Touch your chin, MD, no, try with the soul chopping knife. You can't come for nothing.

People's desire is indeed endless. Ding Ning's harvest is actually enough, but seeing that red coral can't be taken away, his heart is full of reluctance.

With the power of the divine soul, he manipulated the huge soul chopping knife to cut hard at the bottom of the red coral, and the whole underwater cave suddenly set off a terrible spray.

With a "poof" sound, the red coral broke off. Ding Ning, who was happy, opened his mouth and hurriedly incorporated it into the mermaid space.

But unexpectedly, the mermaid threw out the red coral, shook her tail and jumped out. She opened her mouth and spit out a blister to cover Ding Ning. The angry voice also came: "you are crazy. Water and fire are incompatible. My space can help you put Lei Lingjing, but this fire is the top material. It will hurt me if it is matched with my attributes."

"Nani? Fire is the top material?"

Ding Ning swallowed his saliva and said, "this is red coral. How can it be fire material?"

"What red coral? It's the top fire refining material in the world."

The mermaid angrily taught her a lesson, but when she saw the coral bushes all over the ground, her face showed a surprised color, swaying the fish's tail parallel to the ground, stretched out a slender jade finger to poke the ground, and said in surprise: "eh, it's really coral, just a mutated coral. There are Fire Spirit Crystal veins here."

"Huoling crystal vein?"

Ding Ning's brain exploded like a thunder bite, and he understood it in an instant.

Like jellyfish and eels, this coral must absorb the aura in the Fire Spirit Crystal vein and produce variation, so that it can spit fire and swallow the jellyfish's body, and then digest the mutated body to secrete colloidal red coral. The red coral is no longer a red coral in the traditional sense, but a mutated red coral, which is also the top fire refining material.

Compared with ordinary red coral, it can only make jewelry as a collection of art and the medicinal value of calming and brightening the eyes. The mutated red coral is obviously more precious. It is priceless when you meet people who know the goods.

Ding Ning wanted to keep his weapon for use. Unfortunately, although he was tempered by soldiers, he didn't know anything about weapon refining. Holding red coral was also a natural thing.

The mermaid seemed to have an insight into his mind. She hated iron but not steel and vomited bubbles: "Chi You's weapon refining skills are all from the golden heavenly book. It's just that you don't study them."

Ding Ning was stunned and opened his mouth in amazement: "the golden heavenly book? That golden paper is the golden heavenly book? It records the art of refining utensils? Where did Chi you get this heavenly book?"

"I don't know. I only know that Chi You's weapon refining skill comes from the gold paper, but I don't know what's on it, and I don't know where it comes from."

The mermaid shook her head suspiciously. She didn't seem to know why. She suddenly knew these. Her big eyes were full of confusion.

Ding Ning's eyes flashed a fiery color. Although he was more interested in Chi You's medical skills, after military training, he also yearned for Chi You's weapon refining skills.

There are top refining materials like mutated red coral in front of him. If he doesn't want to learn the art of refining, it's sheer nonsense.

But he couldn't understand the ever-changing runes on the golden paper. He couldn't even make a rubbing to study the mysteries, let alone learn the art of refining tools.

But he was not discouraged. Since Chi you could learn the art of refining utensils, he believed that he would be able to pry into the mysteries sooner or later.

"Can you put this red coral in the kid's space?"

Ding Ning looked at the huge red coral tree reluctantly.

"Yes, no matter how low the kid space is, it is also made of space ore without attributes. There is no attribute to overcome each other."

The mermaid vomited bubbles and looked at the ground with disgust: "don't move the fire spirit crystal ore here for the time being. Before you awaken the power of the fire ancestor witch, you can't bear the fire spirit crystal ore vein now."

Ding Ning thought that although Lei Lingjing had stunned the coral insects by coincidence just now, the human "blood man" composed of them still posed a strong death threat to him. What's more, there was a whole fire Lingjing vein below, in which the dense and terrible fire spirit power was enough to vaporize him.

The mermaid swam around in the coral forest. After a moment, she bent down and pointed to a ground and said, "pry open the ground with a soul chopping knife. Here are scattered fire Lingjing, which can be taken away."

Ding Ning was so happy that he manipulated the soul chopping knife to dig the ground and soon dug out two purple fire spirit crystals.

"Yes, the fire spirit crystal is divided into four grades: orange red, red, bright red and purple red. These two are the best fire spirit crystals. Put them away first. I suggest you don't touch the mutated Red Coral here for the time being. When they turn purple red, they can become immortal materials. They are also very rare in the fairy world. If your refining skill can reach the peak, you can use them to make artifact It's not impossible. "

The mermaid thought and said, "this variant red coral is not only the top refining material, but also the best fusion agent. It can make some refining materials with similar properties counteract the repulsion, but also a treasure to assist in refining the body."

Ding Ning's eyes were bright. He didn't care about the fairy material. What he cared about was the fusion of the mutant red coral to counteract the rejection. He couldn't wait to ask, "can this red coral be used as medicine? Is it harmful to the human body?"

"Since it can help refine the body, it is naturally harmless to the human body. It should be used as medicine."

The mermaid shook her tail and said uncertainly.

But Ding Ning's heart fluctuated and couldn't be calm for a long time. If red coral really has the wonderful effect of offsetting exclusion, it will be a great progress in the history of human medicine.

As we all know, with the development and progress of medical science and technology, organ transplantation is no longer a fantasy. Even the heart can be replaced. What else can't be transplanted.

However, whether it is bone marrow transplantation or heart transplantation, even the matching organs of blood relatives, as long as it is transplantation, there will inevitably be rejection more or less.

As a result, even if organ transplantation is performed as a last resort, it can only prolong the life of patients for a few years. Eventually, organ failure will occur due to rejection, and they will have to transplant again or accept the fate of death.

Ding Ning is most worried about the rejection of Feng Jun's prosthesis. Once the rejection occurs, Feng Jun's prosthesis will be abandoned sooner or later.

Ding Ningyi risked doing prosthetic joint surgery for Feng Jun in order to test the feasibility of his theory; Second, we hope to think of solutions before the emergence of exclusion.

At present, the characteristics of mutated Red Coral bring him a new hope. If we can make excellent rejection drugs with red coral, it is likely to solve the problem of rejection of organ transplantation.

So, at the moment, Ding Ning's eyes looking at the red coral have glittered with green light. The greedy eyes made the mermaid shiver and said angrily, "Hey, you don't want to dig all the red coral away. That's a stupid act of fishing in a dry land."

"One, I want another."

Ding Ninghong looked at the mermaid and asked. At this moment, no fairy material is important to exclude drugs.

"It's up to you. As long as you don't empty this place, you can do it. Don't blame me for not reminding you that those jellyfish are coming in. You'd better think about how to escape from them."

The mermaid waved her huge tail irrefutably and returned to Ding Ning's arm and turned it into a tattoo.
