Nie Li took out the Nightmare Demon Pot. The dark jade pot was shining with a faint luster and a mysterious aura.↖

This thing is an ancient treasure. I didn't expect it to appear in the auction house, so Nie Li would take it at all costs. If he missed this nightmare demon pot, Nie Li would definitely regret it to death.

Nie Li stroked the Nightmare Demon Pot with his right hand, and penetrated a trace of soul power into the Nightmare Demon Pot.

The Nightmare Demon Pot suddenly shone brightly, forming an inexplicable connection with Nie Li. Nie Li only knew a little bit of the effect of this Nightmare Demon Pot, and he needed to study more.

One of the functions of the Nightmare Demon Pot is that if ten demon spirits of the same attribute are placed into the Nightmare Demon Pot at the same time, there is a certain probability that they can refine more powerful demon spirits, and of course they may fail.

Nie Li bought so many demon spirits just to refine stronger demon spirits!

"The assassin-type demon spirit has already existed. What is most urgent now is a brutal war demon spirit that can face the enemy head-on!" Nie Li thought for a moment. He bought more than 2,000 brutal war demon spirits. I wonder if he could make a powerful brutal war demon spirit.

Each demon spirit is divided into bronze, silver, gold, black gold, legend, etc. according to the different soul strength before it was killed. This is the standard for defining the city of Glory. What ordinary people don’t know is that the growth of each demon spirit is actually different. Even some very low-level demon spirits, if their growth is strong enough, it is not impossible to kill legendary demon spirits after cultivation!

At the same time, the growth of some special demon spirits is often much stronger than that of ordinary demon spirits, such as Nie Li's Shadow Demon Spirit!

Nie Li divided the growth of the demon spirit into five levels, including inferior, ordinary, good, excellent, outstanding, and god-level. Yingyao Yaoyao is undoubtedly a species of demon spirit with god-level growth. There is no upper limit to the improvement of Yingyao Yaoyao's strength.

Ordinary people don’t know how to distinguish the growth of demon spirits. Only Nie Li knows that just like humans measuring soul power, the growth of demon spirits can also be measured by soul crystals, but the method of discrimination is different.

The second fusion demon spirit will have a very far-reaching impact. Of course, Nie Li has to carefully select it. Even if he cannot get a god-level growth demon spirit, he must at least get an excellent one. Otherwise, he will be too sorry for the nightmare demon pot he bought at a high price!

Nie Li took out ten demon spirit stones and used the soul crystal to test the level of these ten demon spirits.

"The scattered soul cloud group, the inferior demon spirit!"

"The scattered soul cloud group, the inferior demon spirit!"

"The scattered soul cloud group, the inferior demon spirit!"

"The incomplete soul cloud group, an ordinary-level demon spirit!"

...

Nie Li quickly tested these ten demon spirits, seven inferior and three ordinary ones, and Nie Li couldn't help but feel a little disappointed.

"As a matter of fact, it is still difficult to select a person with higher growth from ordinary demons!" Nie Li thought a little depressedly. It would be too difficult to find a demon spirit with a god-level growth like the Shadow Demon Spirit, otherwise Nie Li would not have taken such a great risk to enter the ruins of Gulan City.

However, if these demon spirits that are very trash to Nie Li will be regarded as treasures if they are obtained by ordinary people.

Nie Li put these ten demon spirits into the Nightmare Demon Pot and used his soul power to activate the Nightmare Demon Pot!

In an instant, the Nightmare Demon Pot kept shining, emitting dazzling colors, and halos flowed inside. Nie Li could see that ten lights and shadows kept spinning and slowly merged together.

Finally, a thick fog formed.

About ten minutes later, the light of the Nightmare Demon Pot slowly subsided, and a demon spirit kept swimming at the bottom of the Nightmare Demon Pot like an elf.

Nie Li captured the demon spirit and attached it to an ordinary demon spirit stone, and then checked the demon spirit's growth.

"The slightly complete soul cloud group is already at a good level! The Nightmare Demon Pot is indeed extraordinary! However, a good-level demon spirit is far from enough!" Nie Li shook his head. With his eyes, he definitely looked down on a good-level demon spirit.

Nie Li put this good-level demon spirit aside, then picked up ten demon spirit stones and began to detect it.

The ten berserk demon spirits, preferably one bull demon spirit, is a good-level one.

Nie Li merged again and again.

Refining successfully!

Refining successfully!

Refining failed!

...

The probability of refining failure is still quite small, and it will only fail once in dozens of times. However, after refining more than 60 times, the best thing is an excellent level of berserk demon spirit, and the rest are good-level berserk demon spirits.

"No!" Nie Li shook his head. It was quite difficult to improve the level of these low-level demon spirits.

However, there are so many demon spirits, Nie Li will not give up refining. Among the more than 2,000 demon spirits, there are excellent war demon spirits without refining. There are more than 60 of them selected in total, and there are more than 200 of them in good grades, which is quite good. Some demon spirits themselves have higher growth potential.

For two days, Nie Li continued to refine, and again and again, fusing one inferior and ordinary demon spirit into good ones, and then using good-level demon spirits to continue to fuse into excellent ones. In the end, more than ninety excellent ones were left, and then using these excellent war demon spirits to fuse excellent ones.

The higher the fusion, the greater the probability of failure, and finally the five outstanding demon spirits were successfully fused.

Looking at these five excellent demon spirits, Nie Li was still a little unwilling to accept it. Only ten excellent demon spirits can have a chance to merge with the god-level growth demon spirit, and the probability of failure is very high. When fusion of the excellent demon spirit, the probability of success is only half. If fusion of the god-level demon spirit, the probability of success is one in five, which is good.

The Alchemist Association has sent all the benefits of the recent period, almost one billion demon spirit coins.

After thinking about it, Nie left to meet Nie Hai and Nie En, and asked Nie Hai and Nie En to help him acquire a large number of Brutal War Demon Spirits, and they would pay them some rewards for every purchase of a Brutal War Demon Spirit.

Nie Li gave a very generous reward, so of course they did their best. Soon, Nie Hai and Nie En ran to various chambers of commerce to help Nie Li acquire the Fighting Demon Spirit. After spending hundreds of millions, Nie Li bought tens of thousands of Fighting Demon Spirits and then used the Nightmare Demon Pot crazily.

As the number of fusions increased, Nie Li discovered that the Nightmare Demon Pot also had some obvious changes. The originally chaotic demon pot became very clear, and you could even clearly see the fusion of demon spirits in the demon pot.
