After placing the new batch of animals, Zhong Huan suddenly found that he had collected a lot of animal species. What is not available on the market is available in the Ten Thousand Beast Gu. Although large beasts such as lions and tigers have not yet been obtained, crocodiles, poisonous snakes, Tibetan mastiffs, and eagles should also be regarded as beasts of prey and birds of prey, and I don't know if they meet the conditions for refining Gu beasts.

Originally, Zhong Huan was not eager to refine Gu beasts and Gu Dan, because he didn't know if the Gu beast would be a monster when it was refined, and if Gu Dan would make him a monster if he ate it. But Mimi's kidnapping gave Zhong Huan a sense of urgency. It was Mimi who was kidnapped this time, and Zhong Huan could still rely on the dogs to win, but in case it was someone else who was kidnapped, he could only rely on himself if he wanted to save people.

Zhong Huan knows his ability very well, if he is fighting alone, he is not afraid of Niu Shuoguo and others at all. But if a group of them all take the guy and grab a hostage as a shield, then Zhong Huan will not be an opponent.

It was precisely because he realized that his strength was insufficient that Zhong Huan had the idea of training Gu beasts to make Gu Dan. However, the number of these beasts newly put into the animal breeding cave is still too small, and they are not huge, if they are used for experiments, it is not only wasteful, and may not be successful, but they should be allowed to breed and expand the population size first.

The newly bought beast cannot be used for experiments, but this does not mean that Zhong Huan does not have experimental materials. The meat dogs and vegetable snakes that he first put into the Ten Thousand Beast Gu breeding have already begun to take shape, and they can be used for experiments.

The fact that the dogs rescued Mimi made Zhong Huan realize that the combat effectiveness of the earth dog was not low, and Zhong Huan's earliest meat dog was actually the earth dog. The Tibetan mastiff is a dog, the earth dog is also a dog, the Tibetan mastiff can bite people, and the earth dog can bite people. It can be inferred from this that if the Tibetan mastiff is considered a beast, the earth dog can also be regarded as a beast. Especially the giant earth dog raised in the Ten Thousand Beast Gu, the combat effectiveness released is not necessarily worse than that of the Tibetan mastiff.

Now that we have the test materials, the next step is to refine the Gu Beast. In order to ensure success, Zhong Huan came to the Gu King Palace first and listened to the Gu Beast King's last words again. In this last word, the Gu Beast King gave a detailed account of the method of training Gu beasts and refining Gu Dan.

The first step in training Gu beasts is naturally to hunt beasts, that is, to capture the fierce beasts in the beast breeding cave and put them into the Dou Gu Cave in front of the Gu King's Palace. There is no limit to the method of catching beasts, and the only requirement is that the beast cannot be killed or injured, because once the beast is injured, it will not be able to exert its original strength, and no matter how much it fights, it will not be able to achieve the effect of selecting the best of the best. The beasts of death were naturally even more useless when they were thrown into the Dou Gu Cave.

Such a strict beast hunting requirement made Zhong Huan frown. He had hunted in the Ten Thousand Beasts Gu before, and it was a bow and crossbow and trap that were all in battle, fighting desperately without mercy. But even so, it is not easy to kill a giant earth dog full of wild beasts in the beast breeding cave, let alone capture them alive. Zhong Huan felt that it was a question of whether he could catch up with a galloping giant earth dog.

Fortunately, Zhong Huan has another option in addition to the meat dog, which is to use the vegetable snake for experiments. Don't look at the appearance of the vegetable snake, it looks more scary than a dog, but in fact, the attack power is not as good as that of a dog, and it is not poisonous. Many people are afraid of snakes and dogs, which is completely psychological. And the vegetable snake doesn't crawl fast, it's much easier to catch than the running dog.

There are several kinds of vegetable snakes that Zhong Huan stocked in the animal breeding cave, including black-browed snakes, black-eyed snakes, king snakes, brown and black snakes, and so on. And the requirement for training Gu beasts is to put the same kind of fierce beast in the Dou Gu Cave, which is completely different from the legendary method of refining Gu with several poisonous insects.

Among several vegetable snakes, Zhong Huan finally chose the brown and black golden snake as the target of hunting. There are two reasons for choosing this snake, one is because the length of this snake is short, even if it doubles in the Ten Thousand Beast Gu, it is only three to four meters. The second reason is that this snake has a relatively gentle temperament and generally does not bite if it is not threatened.

Zhong Huan had caught snakes when he was hunting in the Ten Thousand Beast Gu before, and he had some experience, so of course he wouldn't be stupid enough to catch them with his bare hands. He first took a large woven bag from the storage hall, and then found a wooden stick about two meters long and a forked one, and then entered the beast breeding cave.

After Zhong Huan entered the beast breeding cave, he used a wooden stick to beat the grass all the way to startle the snake, and soon found a brown and black snake less than four meters in the vegetable field. The snake has a black background and a brown pattern at regular intervals. When Zhong Huan found it, it was lazily basking in the sun in the vegetable field, ignoring Zhong Huan's appearance.

Although the animals in the Ten Thousand Beasts Gu were more wild and spiritual than the animals in the outside world, their vigilance against humans was very low. Because there is only one human being Zhong Huan who is active in the Ten Thousand Beast Gu, no matter how much he hunts, he only hunts a small number of animals, and it is difficult to pose a threat to an animal population, so there is no animal that regards humans as natural enemies.

It is precisely for this reason that Zhong Huan has an advantage in the Ten Thousand Beast Gu Hunt, that is, he can always strike first. So it wasn't until Zhong Huan got close to the brown and black snake and stuck the seven inches of the snake with the forked end of the wooden stick that the brown and black snake knew that he had encountered the enemy and began to writhe snake body and struggle.

The brown and black snake with a body length of nearly four meters weighs about 20 catties, and it has a lot of strength when it twists. But compared to Zhong Huan's strength, the power of the snake is nothing. Zhong Huan fixed the snake's head with a wooden stick with his left hand, then bent down and grabbed it with his right hand, grabbed the snake's seven inches, and directly picked up the snake from the ground and put it in a woven bag.

After effortlessly catching the first snake, Zhong Huan did the same, and soon caught two more brown and black snakes. These three snakes together weighed fifty or sixty catties, and Zhong Huan had to pour the snake in the woven bag into the Dou Gu hole first, and then continue to catch the snake. After a few trips back and forth, Zhong Huan had accumulated enough snakes in the Dou Gu Cave.

In the last words of the Gu Beast King, the Gu beasts can be divided into four levels, which are ten Gu beasts, one hundred Gu beasts, one thousand Gu beasts, and ten thousand Gu beasts. As the name suggests, ten fierce beasts can produce one ten Gu beasts when they fight each other, and ten thousand fierce beasts can produce one ten thousand Gu beasts when they fight each other. And if you want to refine Gu Dan, you have to use ten thousand Gu beasts.

Although only ten thousand Gu beasts can refine the pill, the existence of ten Gu beasts, hundred Gu beasts, and thousand Gu beasts is not meaningless. In terms of Zhong Huan's current situation, he was already tired and sweating when he caught ten snakes and threw them into the Dou Gu Cave, and he had to catch ten thousand snakes and throw them in, and he didn't know how long this project would last. And with the transition of the Ten Gu Beasts, the Hundred Gu Beasts, and the Thousand Gu Beasts, Zhong Huan was able to reduce this huge project to zero. He could first refine ten Ten Gu Beasts, then use ten Ten Gu Beasts to refine one Hundred Gu Beasts, ten Hundred Gu Beasts to refine a Thousand Gu Beasts, and finally use a Thousand Gu Beasts to refine one Ten Thousand Gu Beasts.

The existence of the Ten Gu Beasts was also very meaningful to Zhong Huan's experiment today. If there was no Ten Gu Beasts, the transition level of Gu Beasts, Zhong Huan would have to catch 10,000 snakes in an experiment, which would be too painful, not to mention time-consuming and laborious, and a waste of resources.

The materials for refining the Ten Gu Beasts were ready, and Zhong Huan came to the Dou Gu Cave. The appearance of this Dou Gu Cave is like a large well, and in the part of the well that protrudes from the ground, there is a circle of jade stones of different colors inlaid on it. These jade stones of different colors represent the different Dou Gu spaces in the Dou Gu Cave. Before Zhong Huan threw the snake into the hole, he had already pressed the black jade that represented the space of the beast, so that he could ensure that the ten snakes were dueling on the ground. If Zhong Huan pressed the green jade that represented the swimming fish space in advance, the ten snakes would have been thrown into the water to duel.

The venue had been prepared in advance, and the beasts were all in place, so Zhong Huan pressed a red jade button on the edge of the Dou Gu Cave. This red jade is the button for the start of the Dou Gu, and it controls the flow of time in the Dou Gu space. If Zhong Huan didn't press the button, the time flow rate in the Dou Gu space would be as static as in the storage hall, and the beasts that were thrown into the hole would not be able to fight. Once the button is pressed, the flow of time in the space will increase, allowing the beasts in the cave to decide the winner in a short period of time.

After activating the Dou Gu Cave, all Zhong Huan had to do was wait patiently. It takes six hundred and thirty-six days to refine the Ten Gu Beasts, but this time is calculated based on the time flow rate in the Dou Gu Cave, and one day in the Ten Thousand Beast Gu is equal to one year in the Dou Gu Cave, which means that Zhong Huan only needs to wait 2.4 hours to get the result.

Zhong Huan was idle at the moment, so he simply practiced boxing on the edge of the Dou Gu Cave. More than two hours passed in a flash, and Zhong Huan found that the red jade button on the edge of the Dou Gu Cave lit up, as if it had changed from a translucent piece of red jade to a crystal clear ruby.

"Yay~ a success!"

As soon as Zhong Huan saw the red jade stone light up, he knew that his experiment was successful, and he almost jumped up with joy. According to the Gu Beast King's last words, when the red jade lit up, it meant that there was only one fierce beast left that was thrown into the Dou Gu Cave, and it had transformed into a Gu beast. This means that the brown and black snake meets the requirements of the fierce beast of the Ten Thousand Beast Gu, and can be refined into ten thousand Gu beasts to make Gu Dan.

The Ten Gu Beasts had already been refined, and all Zhong Huan had to do now was to enter the Dou Gu Cave and take out the Ten Gu Beasts and put them in the storage hall. Only in this way can we ensure that the ten Gu beasts that are refined will not die, if they are kept in the Dou Gu Cave where time is accelerating, the Gu beasts that have been refined will die of old age if they do not starve to death. Only by taking out the refined Gu Beast will the time flow rate in the Dou Gu Cave return to static.

Zhong Huan, who succeeded in the experiment, didn't even think about it, he picked up the fork-headed wooden stick next to him and jumped into the Dou Gu Cave. The seemingly pitch-black entrance of the Dou Gu Cave was actually the same as the gate of the storage hall, it was also a spatial door, not a real big pit. Therefore, Zhong Huan's body did not keep falling after jumping into the Dou Gu Cave, but after falling for a certain distance, he was directly teleported to a flat ground, and the feeling of landing on the ground was as easy as jumping down a step.

This was the first time Zhong Huan had entered the Dou Gu Cave, and as soon as he landed, he looked at it curiously. It's good not to look at it, but he was suddenly a little disappointed when he saw it. Because this Gu Dou space is almost the same as the beast breeding cave space without greenery, there is nothing but a piece of black earth. The only difference is that the Dou Gu space is much smaller than the beast breeding cave, with an area of about 100 square meters, surrounded by stone walls. There were also two caves on the stone wall, and Zhong Huan knew that one of these two caves led to the Storage Hall and the other to the Gu Dan Palace.
