The information Li Xiu learned from Chu Jun was that the level promotion of the trial-taker actually mainly depends on the symbiotic contract.

When the energy of the symbiotic contract accumulates to a level that can be promoted, the level will be promoted naturally, unlike the parasitic contract which requires an opportunity to upgrade.

The process of the symbiotic contract accumulating energy is actually the process of humans improving the quality of the original embryo. Because it is a symbiotic relationship, when the host improves the quality of the original embryo, the symbiotic contract also takes away a part of the energy and improves along with it.

Li Xiu looked at the original qualities of the Evil Spirit Card and the Forbidden Spear, and it was indeed true. The original qualities of both had reached 2.0, the same as Li Xiu's.

No wonder Li Xiu always felt that the quality of his embryo was improving so slowly. It turned out that these two guys had been taking advantage of him.

Li Xiu's original embryo quality can be unified with the Symbiotic Contract because the basic original embryo qualities of both are full values, which is why the values ​​can be unified.

In fact, many trial participants may not be able to achieve unity.

For example, if the trial-taker's original embryo quality is 0.9, and if the original embryo quality of his symbiotic contract is only 0.7, then when the trial-taker's original embryo quality reaches 0.7, the symbiotic contract can be upgraded to a higher level.

If the symbiotic contract is allowed to advance at this time, the original embryo quality of the trial-taker himself will be damaged.

If the original embryo quality of the symbiotic contract is 0.9 and the original embryo quality of the trial-taker is 0.7, then after the original embryo quality of the trial-taker reaches 0.7, there is no way for it to continue to grow. However, the enhancement obtained after the trial can still be provided to the symbiotic contract for continued growth.

So theoretically, only the trial-taker can suppress the symbiotic contract and prevent it from being promoted to a higher level too early. However, in a case like Li Xiu where both the host and the symbiotic contract's embryonic qualities are full, the symbiotic contract still does not move. Chu Jun has never heard of this and does not know what is going on.

Li Xiu thought about it and estimated that the problem might be with his Aurora quality and the parasitic demon larvae in his body.

Although he is a human, because of the Aurora and the Ultimate Light, in some ways, he also possesses the characteristics of a demon spirit.

In addition, the reason why he was a young demon might have prevented him from directly advancing to the next level like the average trial-taker like you.

Li Xiu couldn't figure out the specific reason for a while, so he could only try to continue entering the trial field to strengthen his embryo quality.

But the strengthening didn't respond at all, which made Li Xiu quite distressed.

The only good news is that after burning a large amount of Topas, the Masked Emperor finally upgraded to level B and even awakened a talent skill "Super Acceleration".

After turning on the super acceleration, the Masked Emperor is faster than an airplane. The only drawback is that it has certain requirements for road conditions. In places with bad roads, Li Xiu dare not let it run too fast, otherwise it will definitely overturn.

"You are a B-level demon spirit, but you have requirements for the road surface. This is ridiculous." Li Xiu was a little helpless. He could only hope that the Masked Emperor could get rid of this situation after being promoted to a higher level.

After the Black Death Lord swallowed the magic cores of those Brilliant Black Death Demons, he was upgraded to level C and even awakened a skill called "Roar of the King".

The two talent skills, Roar of the King and Death Aura, are not attack skills, but a kind of blessing skills.

The Death Halo can give his Black Death Demon Legion the ability to heal itself, and general injuries can be recovered automatically.

The King's Roar can unleash the potential of the Black Death Legion, allowing them to temporarily gain a boost in strength and speed.

Black Death Legion: Can summon a legion of black death demons. Currently, thirty black death demons can be summoned and are valid for 24 hours.

The C-level Black Death Demon King can summon thirty Black Death Demons, and their quality has become shining.

According to this growth rate, a B-level player can summon 40 Brilliant Black Death Demons, and an A-level player can summon 50 Shining Black Death Demons. How can an S-level player be upgraded? Does it mean summoning 60 Aurora Black Death Demons?

Li Xiu felt that there was basically no possibility, otherwise the Black Death Legion's innate skill would be truly incredible.

Now Li Xiu is very much looking forward to the growth of the Black Death Demon Lord, but unfortunately he no longer has the resources to allow the Black Death Demon Lord to continue growing.

Even now, the combat power of the Black Death Demon Lord is already very strong. A C-level Radiant Demon Spirit, with thirty C-level Shining Demon Spirits, instantly increases Li Xiu's overall combat power.

With the Black Death Lord, Li Xiu no longer needs to raise so many cannon fodder monsters. He only needs to focus on training a few elites.

"The Black Death Lord must be trained with emphasis. He will be a living signboard of my City of Light in the future. He must shine in the Magic Spirit Competition so that my Black Death Lord rings can be sold better." Li Xiu was originally planning to devote all his efforts to raising the level of the Jedi Knight, but now he has to slow down for a while.

Li Xiu planned to invest all his funds in the Black Death Demon King, and try his best to raise his level to B or A before the Demon Spirit Competition.

Speaking of assets, Li Xiu's own asset is actually just that one ruby ​​ball. His other skill rings, magic rings, talent gems and so on cannot be sold at a high price for the time being and are not easy to sell.

"Should I sell the ruby ​​ball?" Li Xiu had his eye on the ruby ​​ball, but such a large ruby ​​would definitely be sold at a sky-high price. Who could afford the price and be willing to buy it?

Although the bigger the gem, the more valuable it is, for ordinary people, it is not worth using this thing to open the door of trial. At most, it can be used to feed the demon spirits.

If it is used to feed the monsters, it is obviously more cost-effective to buy those smaller rubies. Therefore, although Li Xiu's ruby ​​ball looks priceless, it is a big problem to sell it.

If it is sold too cheaply, Li Xiu himself will not be willing to sell it. If it is sold too expensively, others will not be willing to buy it. Unless one meets a big money sponsor, it will be difficult to sell this thing.

"Where can I find a rich man who can afford the price?" Li Xiu thought about it and realized that most of the people around him were similar to him, a group of poor people. Only Chu Jun was a super rich man.

So Li Xiu planned to give the task of selling the ruby ​​ball to Chu Jun, maybe he could find a suitable buyer.

After handing the task over to Chu Jun, Li Xiu asked Sha Chu to help him purchase black spinel.

Black spinel itself is quite cheap, much cheaper than red spinel. Although a large amount of black spinel has been used recently due to the opening of the Brave Trial Field, this is just a drop in the bucket for the entire market. It's just that the price of black spinel in the City of Light has increased slightly, and the cost-effectiveness is still very high.

Li Xiu asked Sha Chu to collect a large amount of black crystals and buy as many as possible. It can be predicted that after the Magic Spirit Competition, the price of black crystals will rise sharply.

Fortunately, Sha Chu had the investment from Boss Qiu, otherwise he would have no money to help Li Xiu buy the black crystal.

Of course, Li Xiu said it was an advance payment, and once he sold the ruby ​​ball, he would fill this hole.

Now Sha Chu has become a little numb and is too lazy to persuade Li Xiu, the prodigal son, any more. Sha Chu simply sneered at the nonsense that the value of Black Spire Crystal must rise sharply after the Magic Spirit Competition.

But anyway, the City of Light belongs to Li Xiu, so if he wants to squander it, let him do it. No matter how much he tries to persuade him, he won't do it, and instead he gets really angry. Sha Chu feels that he has aged a lot recently, and there seem to be wrinkles at the corners of his eyes.

"No, I have to take a milk bath. The city belongs to others, but my body and beauty are mine. I can't ruin my precious youth and looks for someone else's things." Sha Chu thought so in her heart, but before she could go buy milk, all kinds of things came up again. She was too busy dealing with the affairs of the city.

She has to run around the construction site, take care of the market, and also has a lot of things to do in the City Lord's Mansion, so she has no time to enjoy herself.

Sha Chu now has some doubts as to whether his original decision was wrong or not. Why is his life becoming more difficult than before?

Li Xiu was quite relaxed. He just reported to the trial field every day and fed the Black Death Demon King and the Masked Emperor with the black crystals and topaz collected by Sha Chu.

As time went by, the Demon Spirit Arena was built bit by bit. Although it was only a small part of the plan, it already looked quite decent.

It is estimated that it should be officially available before the start of the Magic Spirit Competition.

Finally, after going to the trial field countless times, Li Xiu got an admission ticket at random and entered the Black Death City again.

There was no blood moon in the Black Death City. After Li Xiu easily killed those ordinary Black Death demons, he began to circle around the city.

He wanted to find the smallest stone house that King Gai Shi mentioned, maybe it would be useful in the future.

After walking around again and again, Li Xiu discovered an astonishing fact. The smallest stone house in the Black Death City was actually the stone house where he found the tablet of the God of Death.

"Could it be that the tablet that King Gai Shi mentioned is the tablet of the God of Killing?" Li Xiu looked at it a few more times without giving up, but the result was the same. There was no stone house smaller than the one with the tablet of the God of Killing.

"No way, the tablet that King Gai Shi mentioned is really the tablet of the God of Death? But that thing doesn't seem to have any other abilities except being able to drag people into the Blood Moon Black Death City. Is it necessary for King Gai Shi to be so in awe of it?" Li Xiu kept wondering in his heart.

He went out and killed another round of mechanical skeletons, but didn't get anything good except the magic core. The only A-grade Flowing Color Magic Core, Li Xiu gave it to the Jedi Knight, so he could raise it slowly.

After returning to the city, Li Xiu went to the Hades House. The proprietress thought he had brought someone with him, but in fact he was the only one there. She was very disappointed.

"Don't worry, boss lady. I'm looking for a candidate for you." Li Xiu said with a smile.

This wine is not something that anyone can drink. If someone dies immediately after drinking it, then the wine would be wasted and the wine would return to the bottle by itself.

"Hmph!" The proprietress just snorted coldly and said nothing.

After Li Xiu left, he thought to himself, "It seems that Blood Moon Black Death City and the ordinary Black Death City should be the same place. If they are two cities in different time and space, the boss lady would not recognize me."

"Li Xiu, we've found a buyer for the ruby ​​ball, but the buyer doesn't have that much cash and wants to exchange it for other items. What do you think?" Chu Jun came to Li Xiu just after he came out of the Black Death City.

"What did he exchange for?" Li Xiu asked.

"Magic Spirit Ring, an S-level Magic Spirit Ring." Chu Jun's eyes lit up when he spoke.

"What S-level magic ring?" Li Xiu frowned.

"Here is the information sent by the other party. You can take a look at it yourself. I think it is quite suitable. Although the ruby ​​ball is also a priceless treasure, the S-level magic spirit is also amazing, and it is of shining quality." Chu Jun opened the laptop and showed Li Xiu the information sent by the other party.

The other party actually had a photo of the demon spirit, which showed a silver lion. Although it was not huge, it was twice as big as an ordinary lion. The silver lion's brown color matched with its majestic body, plus the silver light patterns and gem light on its body, made it look extremely attractive.

"It has already been contract-summoned, how is he going to sell it?" Li Xiu frowned after reading the information.

"This is a photo taken in the past. The previous owner has died. Now this magic ring no longer has a contract and can be contracted with anyone." Chu Jun said.

"I don't think it's suitable." Li Xiu didn't like this S-level silver lion. Its only quality was shining, and it had only two innate skills. In Li Xiu's opinion, this kind of magic spirit was useless except for its higher level.

"Why? How many resources are needed to upgrade an S-level magic spirit? Even if the ruby ​​ball is exchanged for resources, it is still unclear whether an S-level magic spirit can be raised. This one is ready-made, and it has shining quality and dual skills. I think it is quite suitable." Chu Jun took a breath and continued, "And in the magic spirit competition, with this S-level silver lion, it will definitely shock the world."

"It only has the shining quality, and has only awakened two talents. Such an S-level monster will be eliminated sooner or later. We only have one ruby ​​ball, and it will be difficult to find a second one in the future. There is no rush for this." Li Xiu smiled and said, "As for the Monster Competition, don't worry. I have already made preparations and plan to use it to dominate the field."

As he spoke, Li Xiu summoned out the Black Death Devil.

“Glorious Black Death Demon!” Chu Jun was shocked when he saw the Black Death Demon King. His eyes almost popped out. “How can you be so lucky? I have been to the Black Death City so many times, but I have never seen a Glorious Black Death Demon.”

"With good character, everything is possible." Li Xiu said with a smile, "I plan to use it as our main force in the Magic Spirit Competition. After all, the Black Death Demon is the signature of our City of Light. We need to rely on it to attract people to the City of Light. It is not suitable to replace it with other magic spirits."

"What level is it now?" Chu Jun felt that what Li Xiu said was not wrong.

It is true that only the Black Death can represent the City of Light. As long as the Black Death becomes famous, there will be no shortage of people coming to the City of Light. Only when there are more people can the City of Light truly develop.

"Grade C." Li Xiu replied.

"C-level is a bit low. If someone comes to cause trouble, I'm afraid we won't be able to suppress it." Chu Jun groaned.

"So, now I need a lot of gems to feed it. The ruby ​​ball can only be exchanged for gems, not magic spirits." Li Xiu said.

"It won't be long before the Magic Spirit Competition. Is it too late to exchange for gem resources now?" Chu Jun said with some concern.

Not all monsters can eat all the time like Jedi Knights. Ordinary monsters need time to transform gem energy, just like the Masked Emperor. It doesn't mean that it will be promoted immediately after joining Topal.

Only the Jedi Knights and the demigod Setsuna who are parasitized by evil can eat all the time. As long as they have resources, these two can grow quickly.

"Before the competition, it should be enough to be promoted to A-level. If it is B-level, it might be a bit difficult." Li Xiu said after thinking for a while.

"What if an S-level demon appears? For example, the Silver Lion." Chu Jun said.

"The Black Death Demon King can be promoted to A-level, so killing a Silver Lion is no big deal. If it is B-level, it will require some control, but it is not a big problem." Li Xiu said with a smile.

"The Black Death Demon Lord has awakened several innate skills. Let's see what you can do." Chu Jun scolded with a smile.

Li Xiu stretched out three fingers and waved them in front of Chu Jun.

"Are you sure? Isn't your Black Death Lord only at C level? Even if he awakens a talent skill every time he levels up, one talent skill from E level to D level, and one talent skill from D level to C level, that's only two. Where did three come from? Are you crazy?" Chu Jun said with a sneer.

"That's right, there are three. When the Black Death Magic Light is at level E, it comes with a natural skill." Li Xiu said with a smile.

"Oh my god, there is such a thing? How come I have never heard of it?" Chu Jun's eyes suddenly widened.

"First take a look at the skills of my Black Death Lord." Li Xiu let the Black Death Lord release the Black Death Legion skills.

Looking at the shining black death demons appearing one after another, Chu Jun was a little dumbfounded.

Now Chu Jun finally understood why Li Xiu looked down on the Silver Lion. With such a perverted demon spirit, who would spend money to buy the Silver Lion? Of course, he would desperately spend resources to upgrade the Black Death Demon first.

Li Xiu told Chu Jun the details of the Black Death Legion's skill, and then told him his own speculation.

After hearing this, Chu Jun said one thing in a decisive tone: "Even if we have to sell everything we have, we will raise the level of the Black Death Devil. In this Devil Contest, he will be the trump card Devil of our City of Light."

Chu Jun contacted the buyer and told him firmly that they only accepted money or gems, not magic spirits.

After receiving the reply, Li Qingyi couldn't help but frown slightly.

She didn't expect that the other party would actually refuse such a deal. You know, an S-level Shining Magic Spirit has dual talent skills. If it were released, there would be countless trial participants who would spend all their money to get it back.

The other party actually refused the Silver Lion and said that he would only accept money and gems, which was beyond Li Qingyi's expectations.

In fact, if Li Qingyi didn't know the origin of the ruby ​​ball and she was in urgent need of it, she wouldn't have taken out the Silver Lion.

She took out the Silver Lion in order to ensure that she would win the ruby ​​ball, lest someone else get there first. However, she didn't expect that the other party was a weirdo who wanted money instead of magic spirits, which made her miscalculate.
