And the ice phoenix on the opposite hillside no longer dared to pretend to be stupid, and immediately stopped it, and even directly told Cai Yunnan about the black dragon's willingness to eat the dragon clan through spiritual transmission.

Although the black dragon didn't hear the two of them, he guessed most of them. He didn't mind, and offered that if he gave a dragon to eat every year, he could help Qinglin fight the invaders of the underworld.

Cai Yunnan couldn't cry or laugh, this black dragon's breath obviously has a sense of savagery, and this guy can break out of the underworld to round up, indicating that the strength is at least above the thirtieth order, although it has been suppressed in the wilderness, it cannot exceed the tenth order, but once it is recognized by the three secular guardians such as the Qinglin patriarch, it will definitely recover its original strength and become a super combat power!

After thinking about it for a long time, Cai Yunnan proposed to simply exchange the food for the dragons of other worlds, such as demon dragons, dark dragons, or demon dragons! After all, in the Qinglin underground world, there are still dozens of living demon dragons!

The black dragon's time in the underworld is not short, most of his memories have been worn away by the laws of the underworld, and he has lost a lot of anger, but he has also lost some of his wisdom. But after all, he is a million-year-old guy, and he still has a lot of eyes.

In the end, he put forward a request for the competition, if Caiyunnan wins, he can use it as a mount, and he can eat any dragon a year; if Caiyunnan loses, he will provide a real dragon clan a year, of course, if he dies in battle!

Cai Yunnan was really embarrassed, and as soon as he communicated with Hu Menglin, Hu Menglin agreed. In accordance with Hu Menglin's requirements, Caiyunnan clearly proposed three competitions. One each, one Bingfeng.

Black Dragon's best skill is the use of fire, so he directly proposed a test to control fire. Cai Yunnan very simply conceded defeat. Then Cai Yunnan directly brought up a brain teaser provided by Hu Menglin, "A single-plank bridge with a dragon on it, a giant python underwater, a lone wolf in front, and a fiery tiger in the back, how did the extremely weak wind rabbit pass?"

The question that children of how old on the earth will really stump the black dragon and finally admit defeat! As a result, when he heard the real answer, the black dragon himself "fainted"!

Next, Bingfeng's question was obviously tendentious, and he raised a very popular question, "Why are the elves replaced by orcs?"

In the era when the ancestors of the black dragon were imprisoned, the beast clan was still a beast, and this wild world was at the peak of the elven era, how could it be possible to answer this question? Caiyunnan itself is the leader of the Caibei royal family, and the Caibei royal family has experienced the changes of three civilizations, how can it not be answered!

In fact, this guy is secretly happy in his heart, you must know that in the millions of years of the seal, the black dragon clan did not survive by eating dragons, although each generation of the black dragon clan eventually ate each other's remaining one, but, most of the time, they ate other beasts!

If this black dragon is allowed to eat hard, it will not be enough to have thousands of demonic beasts a year! As for the request to be a mount, it is because the black dragon has already decided that this thin sacrifice is the real master of the orc tribe!

However, Cai Yunnan has no interest in this kind of demonic guy at all, and he is not ready to ride it! And the real Hu Menglin has already made arrangements for the black dragon, and in the entire Qinglin tribe, the only one who can accept it is Yu Li Qinghua!

The group who negotiated the terms killed the remaining beasts, and when they returned to the passage to the wilderness, the battle was over. There were less than 2,000 people left in the Sea Clan, and hundreds of them were seriously wounded. And the injured beasts are basically given by the angry elves, after all, these guys go to the elf tribe to grab a few as snacks and eat them, it's no wonder if they don't attract hatred!

Just as Caiyunnan was about to announce the end of the battle and return to the ground, the two Moon Elf brothers who had been in charge of contacting the Chaos Space Resistance Elf came over, "Hu Xi, we found two good things, one is called Bingdou, and the other is called Red Blasting Stone!"

Soon, Cai Yunnan figured out these two things: the soldier bean is actually called the blood bean puppet, which is the fruit of a plant called the blood bean tree. Generally, it can bear fruit in more than five hundred years, and at this time there are five hundred fruits, each of which can transform into a first-order or so demonic beast or orc, and it will turn into ashes in less than ten minutes of battle. In 1,000 years, the fruit will transform into a second-order strength and become 400 pieces, in 5,000 years, it will be a sixth-order strength and become a hundred, and after 10,000 years, it will bear fruit once every ten years, and each fruit will be transformed into a super-level strength and fight for two hours.

It can be said that this is a kind of plant monster!

The red blast stone is a kind of "magic core" of the red flame fish produced in the sea, and the explosive power is very powerful. Moreover, this kind of red flame fish is very common in the chaotic space, but the strength of the red flame fish above the super level is very strong, and it is generally not easy to obtain, in the past few thousand years, the elves have only saved a few hundred, but there are more than 100,000 ordinary third- and fourth-order red blast stones. There are many low-level red flame fish in the sea, which can be said to be inexhaustible.

The elven elders were left here for two months to discuss the relevant matters and the purchase of red blast stones, while Cai Yunnan brought dozens of soldier bean seeds and fifth-order red blast stones, ready to return to Qinglin.

At this time, Xiao Hu had already gone down the water and was coming quickly in the direction of the hanging island. In a hurry, he simply used animal skins to pull up the sails. The result was tragic, the hides were heavy and thick, and they were easy to reverse, and they often fell into the water, which delayed the journey. For this reason, Kun Huadong also made a joke of him.

Eventually, the jungle elves, who knew more about the forest, came up with a solution, and soon after they entered the jungle, they brought back dozens of huge fir banyan leaves, each of which was like a huge flag, and the cavemen connected several of them together, smeared them with silt, and then crystallized them to form several large sails, which were hung on long wooden poles with grass vines, and soon became sailing fast boats.

Generally speaking, in the morning or evening, it is a smooth wind, and in the afternoon, there will be a headwind blowing from the sea, so you can just put down these "sails" and go down the water from the wooden rafts. "Sharpening knives and cutting wood", the wooden platoon only took less than a day and a night to rush to the place where Caiyunnan landed.

Xiao Hu stopped, wait here, he must integrate his identity with Cai Yunnan in one place, otherwise the Sea Clan and the Dragon Clan guardians will be suspicious. Send all the elves on the ship to the surrounding area to find those huge "sails", arrange for the cave people on the top of the mountain and the lower riba people to cut down wood nearby to make wooden rafts, and prepare to transport the corpses of those beasts, blood demons, etc.

These corpses could have been thrown in the forest or in a chaotic space, left to decay and deteriorate, and then picked up as skeletons. However, when Cai Yunnan learned from those elves, the cultivation of the "Soldier Bean Tree" is extremely nutritious, especially the corpses of this super-level demonic beast and underworld beast, which can be used as nutrition for the growth of trees.

Thinking of the special guardian plants of the flower elves, night elves, and moon elves, Xiaohu feels that it is impossible for any plant to only need the nutrient of the fountain of life, and other necessary nutrients are also indispensable, otherwise even if it grows rapidly, the effect will be worse!

So he decided, except for the corpses that the elves in the chaotic space need to leave, all the rest will be frozen and transported back to the Qinglin underground world, anyway, there are places to store them, this level of "flesh and blood fertilizer" is not too common, if it is used well, it may get tens of thousands of super-level "soldier beans" or even more, which is too necessary to fight against the overwhelming army of underworld beasts in the future.

Xiao Hu and Cai Yunnan continued to communicate, until she returned to the Qinglin River with a few cave people on the top of the mountain, Xiao Hu also quietly entered the jungle, Cai Yunnan quickly integrated into Xiao Hu's shadow, exchanging their own information, and then Xiao Hu "alone" out of the jungle, with Ma Wushuang and the few cave people who came out of the chaotic space back to the Qinglin River.

As soon as the silent two groups of cave people on the top of the mountain communicated, they found out that the problem was wrong, but their personalities decided that they would not talk much at all, and even deliberately kept the two secret.

Soon, the cave people who came out of the chaotic space stayed on the shore, constantly urging the sea tribesmen and the elves of the chaotic space to save the corpses of the underworld with ice beads, and then transport them to the banks of the Qinglin River, and throw them on the wooden rafts one by one, with an average of five or six wooden rafts, commanded by a sea tribe, under the impetus of the Qinglin water tribe - hippopotamus people, fish people, conch people, frog people, etc., slowly moving upstream.

Soon, thousands of stupid spirits from Northern Xinjiang who came to support appeared on the way, and they took over the work of pulling fibers, so the whole journey was much faster, and in less than ten days, the corpses of these beasts were transported back to the Qinglin underground world intact, and were quickly decomposed and buried in various valleys. Then under the watering of a large amount of fountain of life, the "Terracotta Tree" thrived, and soon produced the first batch of "first-order" beans, followed by the second batch, and after "five thousand years", the first batch of "seeds" was born, only ten. After getting the seeds, the Qinglin tribe began to cultivate this "Soldier Bean Tree" slowly, only allowing it to grow for 200 years every day, ensuring that a batch of high-quality super-grade soldier beans would be born when it grew to 10,000 years.

In this way, when the first batch of fifty Soldier Bean Trees completed their mission, they obtained 500 seeds and thousands of Soldier Beans of all ranks. I personally tried a super-level soldier bean seed, and the faces of the Qinglin Patriarch and the old man of the horns were happy, this kind of "plant monster" that was simply born for the barbarian war is too important for future wars!

The old man personally went out and went to the "chaotic space" under the sea, personally invited the elves of all races, promised that he would definitely treat them equally, and explained that this space was left by the guardians of the sea clan back then, and there were many relics left by the sea civilization under the sea, and it would definitely suffer from the crazy attack of the underworld in the future. At that time, it is very likely that it will affect the elves.

In fact, the words of the old man were by no means untrue, because the three royal families of the Sea Clan had now sent people to gather here, and they were carrying out sacrifices and communicating at the palace ruins below the sea. If it weren't for the fact that this was a relic left by the first generation of savage ocean civilization, how could it be so fanfare!

In the end, the elves of all races in the chaotic space decided to relocate to the Qinglin underground world as a whole, after all, there are still elves of the five clans, and they also take care of each other, and they are closer to the "Watchstar Great Forest".
