The strength of the demonic beasts brought back by Han Kexin was mostly in the middle of the fourth order, and the purple essence contained in each demonic beast was about equal to three or four purple essence stones, and ten purple essence stones were needed to refine one purple essence pill. The price of purple essence stones is very high, on average, each of them is sold at the price of four or five hundred high-grade gems, and the purple essence pill alone costs four or five thousand high-grade gems for the essence stone part, you must know that alchemy has a failure rate. If you directly use the purple essence stone to refine the purple essence pill, Xiao Yu Shi will not be able to make any profits, and if you are unlucky, you may lose money, if you are exempted from the purple essence stone, you can at least half of the cost, although the price of the fourth-level dragon clan materials is also extremely expensive, but after all, there is production in the city. Even if the fourth-level dragon clan runs out, it can completely be ordinary fourth-level Demonic Beast Demon Crystal and essence blood, and the total price of materials is only between one thousand and two thousand.

Xiao Yu used up the fourth-level materials in the city, refining the Purple Essence Pill a total of thirty-eight times, and failed eighteen times. The Extreme Cold Fire is suitable for refining materials, and has an excellent success rate when used to make potions. Although it can also be used for alchemy, the success rate is not as good as that of the Extreme Flame Fire, and the Extreme Cold Fire cannot be used for forging, and the Extreme Flame Fire cannot be used to refine potions.

Xiao Yu added the Wood Demon Leaf and the Wood Demon Essence to each refining to increase the success rate, and there was also the assistance of the Coiling Dragon Pregnancy Furnace, otherwise it would be good to succeed twenty times.

"Infernal Inferno, you have to find a way to get it."

Xiao Yu couldn't help but sigh, his gaze swept over the row of round pills that emitted purple light in front of him, these pills were crystal clear, like crystals, and there was a layer of purple essence lingering on the surface, which looked very beautiful.

"Purple Essence Pill" is divided into three grades, which are one-star, two-star, and three-star epic pills. Due to the use of high-grade materials this time, the concentration of essence is also very high, there is not a single low-grade pill, sixteen of the refined purple essence pills are two-star "medium-grade purple essence pills", and four of them are due to the grade improvement effect of the wood demon essence, and in the process of refining, they have transformed into three-star "high-grade purple essence pills".

The "Inferior Purple Essence Pill" can easily raise the strength of the early stage of the fourth order to the middle of the fourth order.

The "Medium Grade Purple Essence Pill" can be used by those in the middle of the fourth order to impact the late fourth order.

The "Top-grade Purple Essence Pill" can be used by those in the late stage of the fourth order to attack the peak of the fourth order.

The price of an epic-grade elixir cannot be estimated, and the price of a mid-grade Purple Essence Pill is around 20,000 high-grade gems, and there is no market for it. Xiao Yu just relied on the "Purple Essence Pill" formula, and he could make an ordinary city become a top wealthy city.

Ask Tiancheng is strong, Du Tao is well aware of the amazing benefits brought by alchemy, so the high-priced acquisition of alchemy formulas has never stopped, Xiao Yu has mastered as many as hundreds of third-level formulas, and there are as many as twenty or thirty fourth-level epic formulas. There are many people in Wentian City who have flames, and there are more and more alchemists, Xiaobai is one of the representatives, after she has the purple fire of the earth demon, she also began to enter the field of alchemy, and most of the formulas reserved by Wentiancheng are for the foxes of the institute to learn.

Xiao Yu couldn't help but miss the Elf Clan's Wisdom Ancient Tree Tribe, if only he could be given another chance to enter the space of truth, there were countless ancient alchemy formulas there, and the "Purple Essence Pill" was also one of the most precious formulas obtained at that time.

The purple essence in the Coiling Dragon Pregnancy Furnace was almost used, but there was still a small part of the golden essence left, this golden essence was left by the two bone demon elders who had almost stepped into the fifth-order realm, and there were quite a few of them, the effect of the purple essence on Xiao Yu was no longer obvious, but the golden essence was indeed of great benefit to Xiao Yu, but unfortunately the golden essence was limited, far from enough to hit the fifth-order bottleneck. Xiao Yu is different from ordinary people, the bloodline of the wind and sand gods and demons brings a powerful effect of doubling the spirit, but the difficulty of improving his strength is also twice as big as that of ordinary people, and it is especially difficult to break through the bottleneck.

"Let's save it for now."

After Xiao Yu drank a few bottles of high-grade spiritual power replenishment potions, and refined several high-grade potions, he began to smelt soul gems again, low-grade soul gems were of limited use, and it was not convenient to carry them around. Xiao Yu refined 100,000 high-grade gems into ninety high-grade spirit gems in one go.

Xiao Yu took out a hundred high-level spirit gems from Wentian City, carried nearly two hundred high-level spirit gems and five holy soul gems, and more than a hundred blue-grade magic scrolls, including attack, defense, support and healing, and a large number of potions. As for the twenty-eight Purple Essence Pills refined, Xiao Yu was not prepared to use them for himself, sixteen Intermediate Purple Essence Pills, leaving eight in Wentian City for senior members to exchange for battle merit points, four high-grade Purple Essence Pills were given to Rorome, one was given to Gobido, one was given to the Copper Hammer, and the rest of the Purple Essence Pills were all taken with him.

Han Kexin couldn't close his mouth in surprise when he saw the Purple Essence Pill refined by Xiao Yu: "This kind of pill is too rebellious, although it is not as good as the Creation Golden Pill, but it will definitely cause a sensation when it is brought to the mainland." Especially the alien race whose strength is slow to improve! ”

Xiao Yu nodded: "With the Panlong Pregnancy Furnace in hand, the supply of purple essence is not a problem, the biggest trouble is the lack of fourth-level beast crystals and fourth-level essence blood, otherwise, once the Purple Essence Pill is mass-produced, the strength of Wentian City, and even the strength of the West Coast Alliance and Wentian Alliance will be improved by leaps and bounds in a short period of time." ”

According to Xiao Yu's request, Han Kexin gave three top-grade Purple Essence Pills to the West Coast Alliance, the leaders of the three main races, Rorome, Gobido, and Bronze Hammer. Han Kexin had a total of 100 elite demonic beasts from Rorom and Gobido, and the war against the bone demons had caused a lot of casualties between the two clans, so he always had to give an explanation. After they obtained the top-grade Purple Essence Pill, they would definitely be ecstatic and more loyal to the alliance.

The speed of the improvement of the strength of the alien race is several times or even more than ten times slower than that of humans, and the top-grade Purple Essence Pill is of great significance to them, and it can save them from years of penance, and a batch of demonic beasts is nothing in comparison. As for the casualties caused by the war, they naturally don't care about it, after all, the entire West Coast has a part in the fight against the demonic disaster.

Xiao Yu entered the retreat, drank two bottles of thousand-year-old dragon marrow water in the retreat, and took the Creation Golden Pill. The thousand-year-old dragon marrow water can enhance the strength, and at the same time has a very good effect of improving the physique and stimulating the potential, not to mention the creation of the golden pill, it can also greatly increase the potential, and it can fundamentally improve the strength.

……

On the night of the second day, Xiao Yu came out of retreat, his aura was more than a little stronger than before, and his strength realm had a vague tendency to break through the peak of the fourth order. At this time, Xiao Yu had already touched the threshold of the fifth order, but there was still a long way to go before the real fifth-order realm.

Perhaps it was the reason for inheriting the power of the Ash King's origin, Xiao Yu used the Ash King's Creation Essence to make the Creation Golden Pill to absorb it to an excellent degree, and with almost no effort, his spirit broke through from ten times to twelve times, and now his spiritual strength was much stronger than Shui Lan, who was a descendant of the royal family.

Xiao Yu returned to his residence, Han Kexin seemed to have been waiting for a long time, I don't know why, she watched Xiao Yu become stronger, Han Kexin did not feel pressure, but felt happy and happy.

Han Kexin sat on the bed in a seductive posture, "Congratulations, you are one step closer to the king." In the eyes of all sentient beings, like a pool of quiet spring water, flowing with warm affection, she said coquettishly in a soft tone: "Tell me yourself, how many days have you not come to accompany me?" Hmph, I have a little conscience, remember to come to me before leaving. ”

Xiao Yu hugged Han Kexin's soft and boneless body in his arms, holding the thin waist that was unbearable with both hands, Han Kexin's two slender and straight ** homeopathic coils, the plump round chest was close to the chest, and he couldn't help but say that he would send a hot kiss first.

"Ask Tiancheng is our common home, and the people of the city are indispensable for your leadership. Remember to come back early, there are a lot of beautiful mermaids in the Crystal Sea, don't have a lot of fun. ”

Xiao Yu shook his head with a wry smile and said, "I'm not going to go sightseeing. ”

Han Kexin glared at him viciously, and said without saying anything: "I don't care, you must come back early anyway...... As for the matter of mending the heavenly stone, just do your best, if you really can't get it, forget it, although you are very strong, but it is still a little early to fight with the fifth-order people, don't force it. ”

"Don't worry, I'm not the kind of person who doesn't know how to be flexible."

"It's for the best."

Han Kexin gently untied the thin clothes on his body as he spoke, and the wonderful ketone body was once again displayed in front of Xiao Yu, now that the heart demon has been completely suppressed, the influence of the heart demon emperor on Xiao Yu is already very small, but in front of this stunner, Xiao Yu still feels difficult to control.

Soon the room reverberated with a seductive voice, and spring was in full bloom.

Early the next morning.

Shui Lan came to Wentian City on time.

Xiao Yu said: "How are the preparations over there?" ”

Shui Lan nodded and said, "No problem." As she spoke, she took out a simple magic ring and handed it to Xiao Yu, "You are not a sea clan, this ring is specially prepared for you, it can hide the breath, simulate the breath of other races, and use it to hide the identity of the mainland race." ”

"Ring of the Deceitful", no level, special magic item, Effect 1: Converge your own aura. Effect 2: Simulates the atmosphere of the environment.

This is a very good treasure, and Shui Lan is very thoughtful for Xiao Yu.

Shui Lan said: "I can only help you get here, as for whether you can get the Heaven Replenishing Stone, the rest is up to you, remember to be careful." King Hibo dispatched three elders, and my uncle was only one of them, so as not to be suspected by the other two elders, I can't help you clearly after you set out. ”

"Don't say that, you've helped enough." Xiao Yu put on the ring, his breath suddenly converged, he glanced at Shui Lan and said, "Without further ado, let's go." ”

Xiao Yu activated the teleportation function of the Epic Tower, locked a coordinate, and then opened the teleportation with Shui Lan and left.
