"Don't worry! It's absolutely." Huo Hai smiled.

If the shell of the Xuanwu giant tortoise is high-density bone, then its chemical composition is calcium hydroxyphosphate, which can be dissolved with strong acids. What's more, Ge Xuan and Huo Hai have developed a mixed solution of hydrofluoric acid and antimony pentafluoride that is tens of millions or even over billion times more acidic than strong acids. Even special steel structure products from later generations can be easily melted away. In this era, almost nothing is insoluble.

The reason why Huo Hai was able to produce these chemical products was thanks to Ge Xuan's great progress during this period. He was a person who was born to be very sensitive to the elements of heaven and earth, especially when he saw relevant knowledge in Taiping Qingling and understood it with some explanations from Huo Hai.

The ancestors who had obtained the blood of the Xuanwu Giant Turtle before were probably experts in later generations who studied chemistry. Fortunately, they entered their knowledge into Taiping Qingling. Only Huo Hai, who had received systematic education in later generations, could understand this thing. Of course, if there was no record, even ordinary college students like Huo Hai could not remember these knowledge that they could not use in their minds.

Zuo Ci just took a break in the camp and got up and rushed to the thatched cottage where Tong Yuan was. What surprised him was that his Qimen Dunjia technique had not been hidden from Zhao Yun who was guarding outside the thatched cottage.

"I advise you not to harass the master again." The boy in white robe who turned over the horse quickly took off a long bow from the horse's back. The next second, a sharp arrow shot out like lightning. The arrow directly shot several branches as thick as arms, attacking Zuo Ci who was hiding behind the trunk.

Zuo Ci, who had thought that this big trunk as thick as a bucket, could block Zhao Yun's arrow, saw the sharp iron arrow in front of his nose. After running in the snow for fifty miles, he felt a little cold in the vest. Although Zhao Yun was young, he actually had the same combat power as him. He asked his size to see others. Fortunately, Zhao Yun was not bloody, otherwise he would have suffered some skin injuries just now.

And if Huo Hai was here, he would definitely exclaim, 'Can you be the legendary ninth-grade archer?'

"Little baby, don't be angry. I'm here to talk to your master about things." After Zuo Ci said that, he jumped out from behind the tree trunk, and fell to the ground more than ten feet high, but immediately lost sight. The sound of his speech just now also floated, making Zhao Yun unable to tell the direction.

"The visitor is a master of stealth, and his strength is not inferior to himself." Zhao Yun frowned, and he was secretly shocked. He was full of energy. He put away the longbow, held the silver spear that had been inserted into the snow tightly, and kept changing his gun-holding posture, ready to deal with attacks from all directions at any time.

"Don't be surprised, the person who comes is a guest."

Just as the battle was about to begin, a sound came from the thatched cottage. When Zhao Yun looked over there, a ball of snow in front of the thatched cottage had exploded, and a short guy in Taoist robe jumped out of it. It was Zuo Ci who had previously hid in a tree.

Seeing this Taoist priest who broke through his defense circle and entered the hut, a trace of frustration flashed slightly on Zhao Yun's face. However, since he was a friend of his master, he was a paranormal, and it would not be embarrassing to be unable to prevent him. When his ability goes further in the future, he will be able to defeat him.

"It should be easier to use the earth escape technique to escape from snow!" the old man in the house spoke.

In the thatched cottage, the charcoal fire was extremely warm, and there was not much furniture in the house. Apart from a mat, it was a large charcoal furnace and some smelting and pounding tools. There were also many sharp weapons hanging on the walls, including gun tips and armor-breaking cones.

"The King of Guns has seen my Qimen Dunjia Technique?" Zuo Ci shook the snow foam on his body without seeing it at all, and half of his butt collapsed onto the mat.

However, before his butt was touched by the straw mat, he felt a strong wind coming towards him. The most terrifying thing was that he didn't know where the strong wind came from, and it seemed to be coming from the ground, so he didn't know where to hide. He had to tighten himself and activate his internal strength to defend himself.

Soon, the hem of his robe was blown up by a strong wind. Not only did he not touch the surface of the table, but he was pushed forward by the strong wind for two or three steps before he could stop.

"Is this the energy? It's mysterious, but I'm a guest after all. If you don't let me sit down, how can you talk about it?" After Zuo Ci knew the intention of Tong Yuan's move just now, she no longer wanted to sit on the other person's grass and return to her hippie smile.

"I like quietness. Since the construction of this thatched cottage, I have not welcomed foreign guests. If you have anything to do, just say it. If you have nothing to do, come from and go back to wherever you want!" Tong Yuan, who was holding a sharp cone in his hand, turned his head and looked at Zuo Ci slightly, guessed his identity, and spoke.

"I ran to this deep mountain forest to find you, of course, for the blood of the Xuanwu giant turtle. If I tell you, someone can break through the defense of the Xuanwu giant turtle, are you willing to cooperate? After the matter is completed, you will divide the blood of the turtle evenly." Zuo Ci said straight to the point.

"Is that so? He has divine weapons like Gan Jiang Mo Ye? I said frankly that even divine weapons like Gan Jiang Mo Ye can't break the shell of the Xuanwu giant turtle. This is why few people have used divine weapons to find the Xuanwu giant turtle over the years. Their ancestors have tried it." Tong Yuan said with a dim expression.

He went to the turtle cave several times to explore, but because he had no sharp weapon to break the defense of the Xuanwu giant turtle, he did not get the blood of the Xuanwu giant turtle, so he began to study and smel. Unfortunately, he tried all the methods he could try, but he was unable to create a weapon that could break the shell or scales of the Xuanwu giant turtle. He had already made plans to give up.

"You have always wanted to use sharp things to break the scales of the Xuanwu giant turtle. Have you ever thought of using soft things to break it?" Zuo Ci kept a secret.

"Soft things? How can it work? That's the scales of the Xuanwu giant turtle, which are harder than gold and iron." Tong Yuan looked at Zuo Ci in an impossible look.

From the expression on Tong Yuan's face, Zuo Ci knew that he wanted to know what soft thing could break the scales of the Xuanwu giant turtle, and wanted to give it a try.

"Three days ago, I saw someone with my own eyes melting the Bailiang Stainless Steel with just a few drops of water. The water poured onto the steel is like hot water pouring onto the snow, and it melts in an instant." Zuo Ciyu said temptingly.

"What kind of water is it?" Tong Yuan stared at Zuo Ci with an eagle-like look.

At this moment, Zuo Ci knew that even if he tried his best, he could not escape from him.

"The name is too long and difficult to remember. However, I brought that person to you. His condition is to work together to get the turtle blood. After the matter is completed, half of it. If you agree, you will lead him to the cave of the Xuanwu Giant Turtle." Zuo Ci said seriously.

"Still half?"

After hesitating for a while, Tong Yuan said, "Okay, but if that kind of water can really break through the scales of the Xuanwu Giant Turtle, I will need another one after the matter is done."

"Can I ask the reason?" Zuo Ci looked at Tong Yuan and said.

"It's no secret. The Xuanwu giant tortoise cannot produce too much blood each time. It can only be enough for two people to train their bodies. Otherwise, it will damage its origin and make it wake up and go crazy. By then, no one can leave alive." Tong Yuan replied.

"That's it! It seems that our plan to obtain a large amount of turtle blood will not work." Zuo Ci said a little disappointed.

Who doesn't want his invulnerable body? Zuo Ci is no exception. Therefore, the people who came to take the blood of the turtle wanted to get a portion for themselves, but now it seems that it's not possible.

"A lot, hahahahahaha, you're thinking too much. Even if you can successfully retrieve blood this time, the next time I will take blood, it will be at least ten years later. During this period, I will still find a large number of strange beasts to nourish this guy. Do you think this kind of essence and blood that can strengthen the body is so easy to obtain? Without eating hundreds or thousands of psychic strange beasts, the origin of the Xuanwu giant turtle will not reach a sufficient state. Instead, the essence and blood taken out when its origin is abundant, it will not achieve the effect we want." Tong Yuan, an expert in turtle blood research, said.

You must take up to two people at a time, and within ten years, hundreds of psychic beasts need to be used to nourish the Xuanwu giant turtle before they can get blood again. The strange beasts are not so easy to find. Therefore, even if they can easily obtain the blood of the Xuanwu giant turtle, it is impossible to mass produce them.
