With hundreds of water spirit crystals being collected, the polyps still did not react, Ding Ning was ecstatic in his heart, haha, it seems that the polyps will not be nosy.

For jellyfish, although he is afraid but not afraid, but for this immeasurable polyp, he is also worried for a while, after all, the red flame spit out by this thing can actually melt the hard shell of the jellyfish, which shows how terrifying the temperature of the flame is, and he does not want to be turned into nourishment for red coral by polyps.

Frightened, he collected more than 100 pieces of water spirit crystals, and seeing that the polyps did not react, Ding Ning no longer had any scruples, and began to collect water spirit crystals in a big way.

Just when he was happily collecting the water spirit crystal, suddenly, a strong life-and-death crisis made him creepy, and he froze on the spot, not daring to move, looking at the "bloody man" that suddenly appeared in front of him in horror, lest he anger it.

There is more than one "blood man", there is a "blood man" out of every red coral, and under Ding Ning's heavenly eyes, these "blood men" are all composed of polyps.

I don't know if it's because they've never seen a human before, these polyps curiously imitate Ding Ning's shape, forming a humanoid "blood man", and also imitate his movements to turn their heads, bend over, and pick up ......

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

He would rather face a swarm of jellyfish than a monster capable of emitting terrifying heat.

Tremblingly, he took out a handful of spirit crystals, nodded with a crying face, and said, "Give it back to you, can't I not want it?"

Who knows, those "blood people" felt the spirit crystal breath in his hand, and they were so frightened that they retreated again and again, and they couldn't even maintain their human form.

They're afraid of the Water Spirit Crystal? It's impossible.

Ding Ning looked at these "blood people" in disbelief, and they couldn't even maintain their human form in horror, as if they were fleeing, they fled back to the red coral, and in an instant, the cave was restored to tranquility.

A tingling sensation came from his hand, and Ding Ning realized that he had made a mistake in his hurry, and he had mistakenly taken out a purple thunder spirit crystal in a handful of water spirit crystals.

Thinking of the frightened appearance of the polyp before, Ding Ning couldn't wait to laugh wildly, it was really by mistake, I didn't expect this polyp to be afraid of Lei Lingjing, great, hahaha!

With a salivating look in his eyes, he took the Lei Lingjing with a sinister smile and approached a red coral that was about three meters tall.

With a "buzz", the polyps in the red coral scattered, fled to other red corals to live, and never dared to stay in this red coral again.

Sure enough, Ding Ning smiled, picked up this red coral and broke it hard, wanting to put it into the mermaid space......

However, it didn't break, Ding Ning's jaw almost fell off, Nima, he now has at least tens of thousands of catties of strength, and he actually broke a coral tree, this is too ghostly, right?

Ding Ning, who did not believe in evil, turned red, the green tendons on his arms burst out, and he yelled "open", and even used the strength to breastfeed, and the result was ...... Still not moving.

"Damn, I don't believe it yet!"

Ding Ning took out the silver knife and slashed at the root of the red coral.

With a sound of "oops", there was a sound of gold and iron resonating, and Ding Ning's arm was sore, but the red coral did not even appear with a white mark.

Ding Ning was dumbfounded now, and he still wanted to force back the polyps and go back to make a fortune with a red coral, but he didn't expect to even cut it constantly.

This red coral is too hard to be outrageous, but when he thinks that this thing is likely to be something that is decomposed from the extremely hard shell of the jellyfish and solidified again, Ding Ning doesn't find it incomprehensible.

Touching his chin, MD, if you can't try it with a soul slashing knife, you can't come for nothing.

People's desires are really endless, and Ding Ning's harvest is actually enough, but seeing that such a good thing as red coral cannot be taken away, his heart is full of unwillingness.

With the power of the divine soul, he manipulated the huge soul slashing knife and slashed at the bottom of the red coral, and the entire underwater cave Huo Ran set off terrifying waves.

With a soft sound of "poof", the red coral was actually broken in response, and the happy Ding Ning grinned widely and hurriedly put it into the mermaid space.

Unexpectedly, the mermaid threw out the red coral with great resistance, jumped out with a wagging tail, opened its mouth and spit out a blister to envelop Ding Ning, and an angry voice also came: "You are crazy, water and fire are incompatible, my space can help you hold the thunder spirit crystal, but this fire-based top-level material, which is compatible with my attributes, will cause harm to me." ”

"Nani?fire top-grade material?"

Ding Ning swallowed and foamed, and said with a confused expression: "This is red coral, how can it be a fire-based material?"

"What red coral, this is the top-level fire-based refining material in the human world. ”

The mermaid was angry and said a lesson, but when she saw the coral bushes all over the ground, her face showed a look of surprise, swayed the fish's tail parallel to the ground, stretched out her slender jade finger and poked the ground, and said in surprise: "Hey, it is indeed coral, but it is a mutated coral, and there is a vein of fire spirit crystal here." ”

"Fire Spirit Crystal Vein?"

Ding Ning's brain exploded like thunder, and he instantly understood.

This polyp must be the same as jellyfish and eels, absorbing the aura in the veins of the fire spirit crystal and producing mutations, so that it can breathe fire and devour the corpse of the jellyfish, and then after the digestion of the mutated body, it secretes colloidal red coral, and the red coral is no longer red coral in the traditional sense, but a mutated red coral, which is also a top-level fire refining material.

Compared with ordinary red coral, which can only be used as a collection of art and the medicinal value of shocking and dazzling, the mutated red coral is obviously more precious, and it is simply a priceless treasure when encountering knowledge.

Ding Ning wanted to keep his refining weapon to use, but unfortunately although he was refined, he didn't know anything about alchemy, and holding red coral was also a tyrannical thing.

The mermaid seemed to be able to perceive his thoughts, and spit bubbles with hatred that iron is not made of steel: "Chi You's alchemy skills are all from the Golden Heavenly Book, but you don't study it." ”

Ding Ning was stunned, and opened his mouth wide in astonishment: "The Golden Book of Heaven? That golden piece of paper is the Golden Book of Heaven?

"I don't know, I only know that Chiyou's alchemy came from that golden paper, but I don't know what exactly is on it, and I don't know where I got it. ”

The mermaid shook her head suspiciously, as if she didn't know why she suddenly knew this, and her big eyes were full of confusion.

Ding Ning's eyes flashed with a fiery color, although he was more interested in Chiyou's medical skills, but after military training, he also longed for Chiyou's alchemy.

There was a top-level refining material like Mutant Red Coral in front of him, and it would be pure nonsense to say that he didn't want to learn alchemy.

But he couldn't understand the flickering and changing runes on the golden paper, and he couldn't even do it if he wanted to rub it down and study the mysteries in it, let alone learn alchemy.

But he was not discouraged, since Chi You was able to learn alchemy from it, he believed that sooner or later he would be able to peek into the mysteries of it.

"Can this kind of red coral be placed in that little ghost space?"

Ding Ning looked at the huge red coral tree with some unwillingness.

"Yes, no matter how low the ghost space is, after all, it is also made of non-attribute space ore, and there is no such thing as attribute restraint. ”

The mermaid spat bubbles and looked at the ground with a disgusted expression: "Don't move the fire spirit crystal mine here for the time being, before you awaken the power of the fire ancestor witch, this fire spirit crystal vein is not something you can withstand now." ”

Ding Ning thought it was true, although he used the thunder spirit crystal to deter the polyps by coincidence just now, the humanoid "blood man" they composed of them still brought him a strong threat of death, not to mention that below was a whole vein of fire spirit crystal, in which the terrifying fire spirit power was enough to vaporize him.

The mermaid swam around in the coral forest, and after a while, he bent down, pointed to a place on the ground, and said, "Use the soul slashing knife to pry open the ground, there are scattered fire spirit crystals here, you can take them." ”

Ding Ning was overjoyed in his heart, and manipulated the Soul Slaying Knife to start digging the ground, and soon dug out two purple-red fire spirit crystals.

"Yes, the fire spirit crystal is divided into four grade colors: orange-red, red, bright red, and purple red, these two are the best fire spirit crystals, you put them away first, I suggest you don't touch the mutated red coral here for the time being, when they turn into purple red, they can become immortal materials, and they are also extremely rare in the fairy world, if your alchemy skills can reach the peak, it is not impossible to use them to create an artifact." ”

The mermaid pondered and said, "This mutated red coral is not only a top-level refining material, but also the best fusion agent, which can allow some refining materials with similar attributes to offset rejection, and it is also a treasure to assist in refining. ”

Ding Ning's eyes lit up, he didn't care about any immortal material, what he cared about was the fusion of the mutated red coral to offset the rejection, and he couldn't wait to ask: "Can this red coral be used in medicine, is it harmful to the human body?"

"Since it can help refine the body, it is naturally harmless to the human body, so it should be able to be used in medicine. ”

The mermaid wagged her tail and said uncertainly.

Ding Ning's heart fluctuated, and he couldn't calm down for a long time, if red coral really has the miraculous effect of counteracting rejection, 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, transplanting organs is no longer a fantasy, even the heart can be replaced, and what else cannot be transplanted.

But whether it is a bone marrow transplant, a heart transplant, or a matching organ of blood relatives, as long as it is a transplant, it is inevitable that there will be more or less rejection.

As a result, even if an organ transplant is forced to undergo surgery, it can only prolong the patient's life for a few years, and eventually the patient will still suffer from organ failure due to rejection, and he will have to re-transplant or accept the fate of death.

Feng Jun's prosthetic leg was reborn, and Ding Ning was most worried that there would be rejection, once rejection occurred, Feng Jun's prosthetic leg would be scrapped sooner or later.

The reason why Ding Ning took the risk of giving Feng Jun a prosthetic articulation surgery was to test the feasibility of his theory, and second, he hoped to think of a solution before rejection occurred.

At present, the characteristics of mutated red coral give him a new hope, if he can use red coral to make excellent rejection drugs, then it is very likely to solve the rejection problem of organ transplantation.

Therefore, at this moment, Ding Ning's eyes were already flashing with green light when he looked at the red coral, and his greedy eyes made the mermaid shudder, and said angrily: "Hey, you don't want to dig up all the red coral, it's a stupid act to dry up and fish." ”

"One plant, I'll just want another one. ”

Ding Ning's eyes were red, and he stretched out his fingers like a demon and looked at the mermaid and pleaded, at this moment, no immortal material is as important as the rejection drug.

"Whatever you want, as long as you don't hollow out this place, you can do it, don't blame me for not warning you, those jellyfish are about to come in, you better quickly think about how to escape from them." ”

The mermaid swayed its huge fish tail noncommittally, and fluttered back to Ding Ning's arm to turn into a tattoo.
