…… The next day, Chu Duan was not in a hurry to leave the Nightmare Demon City, which is a tenth-level city, which can be said to be the most prosperous city, and here, there will be a lot of things that Chu Duan needs.

After three years of living on the prison island, Chu Duan also collected a lot of valuable things, sold all these things, and then used them to buy soul crystals, which could greatly improve the strength of his soul pet.

The training of soul crystals cannot be continued forever, after all, the body of the soul pet also has a certain saturation, if you absorb too much soul crystal energy in a short period of time, it will not be able to truly transform into the power you need, which will not only cause some damage to the soul pet's body, but also waste the extremely expensive soul crystal.

Chu Duan's current Mo Ye had already reached the fifth rank and ninth order, and if he wanted to break through to the sixth order, he would probably have to rely on battle alone, I am afraid it would take a long time.

And Mo Xie has not been trained by soul crystals for a long time, if he can get a sixth-level dual-attribute soul crystal, he will be able to enter the sixth stage one hundred percent, and the power of the attribute will be even purer.

In the first year of entering the Prison Island, Chu Duan already had a soul crystal worth 100,000 gold coins, and after that, Chu Duan faced more strong people and got more valuable soul crystals from their hands, and when the prisoners on the Prison Island died almost dead, Chu Duan himself estimated that he had a soul crystal of 600,000 gold coins.

If you add the book of soul skills, soul costumes, medicinal materials, and items you get from those prisoners, you can barely have a million gold coins!

One million gold coins is enough to buy a highly talented Commander-level soul pet.

It's just that Chu Duan would rather exchange all these gold coins for soul cores and soul crystals to make his existing soul pet strength stronger.

…… The next day, Chu Duan planned to let Ting Yu take him to the luxurious Nightmare Demon City Exchange, but Ting Yu gave Chu Duan a good suggestion, that is, to dedicate all these somewhat messy things to the Nightmare Demon Palace, in exchange for magic coins that measure the contribution to the Nightmare Demon Palace, when the Nightmare Demon Coins reach a certain level, they can directly use the magic coins to exchange the required items.

The treasures in the Nightmare Demon Palace were piled up, this method did save Chu Duan a lot of trouble, Chu Duan dedicated all the things worth one million gold coins to the Nightmare Demon Palace, and Chu Duan quickly exchanged for a sixth-level fire and beast dual-attribute soul crystal worth 300,000.

After that, Chu Duan made another purchase and exchanged for a fifth-level three-attribute soul crystal worth 300,000 yuan, thunder, dark, and demon spirits.

The Ice Sky Spirit had also reached the fifth rank and ninth order, so Chu Duan did not hesitate to exchange it for the purest sixth-level ice attribute soul crystal worth about 200,000 gold coins.

Finally, it is the wood attribute soul crystal of the Demon Tree Elf, and the value of the sixth-level soul crystal of the wood attribute is not very high, only 100,000 gold coins.

He obtained a fourth-level dual-attribute soul crystal from Zhou Luling and the remaining 100,000 gold coins worth of exchange magic coins, and purchased all the best quality soul cores in one go, ensuring that the food of his soul pet was the best.

Soul Cores and Soul Crystals can be said to be the biggest consumables for soul pet masters, in order to make soul pets grow better, no soul pet master will be stingy with their money in the purchase of soul cores and soul crystals. And Chu Duan belongs to the kind of guy who spends a lot of money on the cultivation of soul pets, and the purchase of hundreds of thousands of three-month soul cores, even the patriarch of the big family in Gangluo City is estimated to be so generous!

Chu Duan was also wearing a fourth-level soul armor, which could be said to have saved Chu Duan's life several times, and its value was close to 500,000.

However, with the improvement of Chu Duan's current strength, the effect of the fourth-level soul armor has gradually decreased, and Chu Duan has begun to consider at least matching himself with a sixth-level soul armor.

The defense of the sixth-level soul armor reaches level six, and then applies the ice armor skill to yourself, the defense can reach level seven and approach level eight, and when fighting, you can occasionally resist a few more ferocious attacks for your soul pet.

The price of the fourth-level soul armor has already reached 500,000 gold coins, and the sixth-level soul armor requires a terrifying five million gold coins, which has increased tenfold.

Five million gold coins was an unattainable number for Chu Duan, and with his current consumption of soul cores and soul crystals, it was estimated that it would be quite difficult to save enough five million gold coins.

After the soul crystal and soul core were purchased, Chu Duan also directly trained his four soul pets with soul crystals.

Mo Ye is still trained according to the strict 2:1 beast attribute and fire attribute, and the sixth-level soul crystal, if nothing else, will definitely be able to improve Mo Ye to the sixth stage, and the flame ability will definitely be able to improve a lot.

The Night Thunder Dream Beast is in the first order of the fifth stage, and it is only suitable for the fifth level of soul crystals, but the Night Thunder Dream Beast is the three attributes of thunder, darkness, and demon spirits, and its soul crystals are very valuable, and it costs a lot of money to cultivate. And after some training of this fifth-level soul crystal, it should be able to make the Night Thunder Dream Beast reach about the fifth rank and fourth order.

Chu Duan focused more on the demon spirit attribute and dark attribute of the Night Thunder Dream Beast, and the thunder system was purely used as a thunder resistance, so the three attributes of the soul crystal thunder, darkness, and demon spirit he purchased were dark 1:2:2 for training.

The pure ice attribute of the Ice Sky Elf, Chu Duan will never add any useless attributes to it, according to Chu Duan's estimation, if the Ice Sky Spirit has been cultivated with the ice attribute, after the higher stage, it is absolutely possible for his ice skills to shake the soul pet of the Commander or even the Monarch level.

The racial level is not necessarily the most absolute potential, if the unilateral power is exclusive, if the soul pet of the fire monarch level meets an ice elf who uses ice skills to be superb, even at the same stage, he will have to suffer a lot.

Therefore, even if he reaches the soul master level and can control the commander-level soul pet, Chu Duan will not despise the general-level ice sky elf, after all, the ice sky elf's current ice ability can already cause very much damage to the commander-level soul pet, keep a distance to fight, the ice sky spirit is a five-stage ninth-order commander-level ice soul pet!

If the sixth-level ice attribute soul crystal is completely absorbed, it will not be a problem for the ice sky elf and Mo Ye to enter the sixth stage, and if these two soul pets enter the sixth stage, Chu Duan's strength will have a small leap.

As for the Demon Tree Warrior, Chu Duan also cultivated with pure wood attributes, completely giving up the effect of the beast attribute, hoping that the Demon Tree Warrior could become a powerful soul pet who controlled the situation on the battlefield.

When the wood soul pet fights alone, except for a slight advantage in dealing with beast attribute soul pets and demon spirit attribute soul pets, it is difficult for others to have an effect, but in team battles, wood soul pets are the absolute battlefield overlord!

The Demon Tree Warrior is still in the fifth and sixth ranks, and it is not very wise to use the sixth level soul crystal now, so Chu Duan plans to use the wood soul crystal to train the Demon Tree Warrior when the Demon Tree Warrior reaches the fifth and ninth ranks, so that it can directly enter the sixth stage!

............ "Young Master Chu, this is already the twentieth person to challenge you. Qinghe put a stack of challenge books in front of Chu Duan's table and said with a bitter face.

"Oh, which ones are stronger?" Chu Duan asked.

The training period has ended, and Chu Duan just needs some people to practice his hands.

"This is known as the strongest young man in the Blue Nightmare Demon Palace-Guo Xian, and this Ruan Shan Wei Shao, this young master of Fengjing City......" Qinghe read in one breath Five young powerhouses who are all well-known in the Nightmare Demon Palace.

"Tell me about their strength." Chu Duan asked.

Qinghe immediately rummaged through it and told Chu Duan about their soul pets:

"Guo Xian's Blue Nightmare Demon has reached the sixth rank and fourth order, and is the strongest main pet, and Ruan Shan Wei Shao is said to have a fifth rank and fourth order commander-level soul pet. The young master of Fengjing City seems to be controlling a seventh-stage blue bird......"

"Oh, then these five, take their challenge." Chu Duan said.

"Five." Qinghe was stunned, and thought to himself: The young master is the young master, and he actually took five challenge letters.

"Then how does the young master plan to arrange the battle period, is Ruan Shanxiao put it in the first week, and the young master of Fengjing City will put it in the second week, or the time interval will be longer, so that you will also have enough time to rest in battle." Kiyoha asked.

Chu Duan raised his head and glanced at Qinghe, a servant girl who was a little natural, but said, "I don't have that much time, arrange them all tomorrow, and the day after tomorrow, I will leave here and go to Gangluo City in Luo Domain." ”

"Huh? You'll want to schedule it all on the same day! Qinghe opened his mouth in surprise, blinked his eyes, and looked at Chu Duan in a daze.

"Yes, do it."

Before Qinghe could react, he once again confirmed that Chu Duan really wanted to arrange these five opponents on the same day, so he was extremely surprised to send the challenge book back............ The eighteen-year-old King of Prison Island is already a very remarkable figure in the Nightmare Palace. Especially the rumors in recent times, and even in the huge Nightmare Demon City, there are many forces who know about Chu Duan, the Henghai Nightmare.

The fact that a genius is born without any warning is often a surprise, and the surprise is followed by the dissatisfaction of many people, wondering if the genius really has the strength, or if he was lucky enough to survive the prison island.

For the sake of prestige, for the sake of fame, there will definitely be many high-minded people who will challenge this king of the prison island.

However, it was precisely because of this challenging atmosphere that the young masters of the entire Nightmare Palace did not expect that an astonishing news was exploded in the Nightmare Palace!!

In one day, take on the challenge of five young powerhouses!!!

There are a lot of arrogant people in the Nightmare Demon Palace, especially those who are powerful in the younger generation, and in this place where the strong are like clouds, there will never be a shortage of amazing and incomparably important things.

However, the incident of fighting five young powerhouses in one day has never happened in the Nightmare Palace!!

The challenge must be when the difference in titles is no more than one level, that is to say, those who are qualified to challenge Chu Duan are all young masters with the title of level 6 in the Demon Palace!

Accepting the challenge of five young masters with the title of level 6 in one day is absolutely unprecedented in the Demon Palace! The arrogant level of Henghai Nightmare is simply to the point of making all the young masters outrageous!
