Long Yi was silent for a while, thought carefully, and then looked up at the emperor, and stopped talking.

"If you have something to say, I've never seen you like a mother-in-law. The Emperor obviously saw that Long Yi had an idea.

The dragon nodded his head and whispered, "I have an idea, but this idea is extremely immature and full of great threats, and if you are unlucky, you may bring down the entire empire." So I'm not going to tell you right now, but, considering you're smarter and more cunning than I am, I think you should be able to make a precise judgment about how threatening this thing is, so I'm going to tell you. So now I'm in a conflict, whether I tell or don't tell you. ”

Crane looked at Ryuichi's eyes, and he knew what Ryuichi was. This young man of only nineteen years old has abilities and enthusiasm that are completely inconsistent with his age, and the successive crises that the empire has experienced almost all rely on Ryuichi's activity in them to easily save the day. The research of the crystal nucleus of the White Dragon Empire is from Ryuichi, the battle armor of the White Dragon Empire is from Ryuichi, and the research of molten beasts is also from Ryuichi.

Long Yi didn't ask for anything in return for what he did, and he didn't even ask the emperor for a medal!

As the first emperor once said to Crane, if Long Yi becomes the emperor of this country, maybe soon, this world will be unified under the White Dragon Empire. And he also said that if Ryuichi wanted to kill the country, it would only be a matter of minutes.

However, Crane chooses to trust. Because, he can feel it. Ryuichi really doesn't have any interest in this country. The only thing that worries Long Yi must be Elsa, who is far away in the upper plane.

This stage in the Anthropocene realm is still too small.

But now. He could see Ryuichi's troubles.

"No, I don't think you should have told me. "Because if you tell me, there's a good chance I'm going to make an irrational decision in the face of the huge gains that come with success." Maybe I'm cunning, but I lack enough rationality. Ryuichi, I hope you can make a judgment for me. This thing. Can it be done? ”

Long Yi looked at Crane, and he saw the absolute trust in the other party's eyes.

"I need to think again, I always thought I was bold enough. But I really don't dare to jump to conclusions about this matter. Perhaps, I should go to some experts for help. Long Yi said very seriously.

"Okay, if you've decided on any plan. Please let me know. Within the purview of my emperor, whatever you want, I can absolutely satisfy you. Crane said.

"Really?"

"Really. ”

"What if I want your throne?"

"Here you too. ”

"Damn, it's so simple! You and your father are really biological father and son. Ryuichi shook his head and left.

Looking at the back of Long Yi leaving, a smile appeared on the corner of Crane's mouth: "If you are given a position as an emperor in exchange for the destruction of the enemy, then who else can this position belong to you? ”

Erin and Ryuichi leave the palace, and the two go straight to the research institute.

In fact, recently, Erin can clearly feel a faint uneasiness on Long Yi's body, in the past, Long Yi looked like he had excess energy wherever he went. But in recent times. The time that Long Yi spent in a daze increased significantly. Erin knew that Ryuichi was worried about the affairs of the mad demon plane, but she couldn't help much.

"Let's go to the Undercity. "Walk on the road. Long Yi said suddenly.

"What?" said Erin.

"I said, let's go to the Undercity. The Undercity has a long history of using crystal nuclei, and they may be helpful for the current situation. Long Yi said.

"Why don't we show them the crystal nucleus and molten beast core we made by the way, maybe there is still room for improvement. Erin said.

"Makes sense!"

rushed to the research institute, and after Long Yi explained his intentions, he immediately won the support of several research institutes. After all, he is the only person who has really dealt with the Undercity at present, and the use of crystal nuclei in the Undercity has reached a peak. With the help of the Undercity, the quality of these crystal nuclei will be raised by about a notch.

The Dark Clan is essentially the core clan created by the giants back then, and the dragon is the giant who activated the Dark Saintess, and has actually become the master of the Dark Saintess, but he has never exercised this power, pushing himself and others, and no one is not disgusted with the fact that he will have a master.

However, Long Yi really needed their help, so he could only scratch his head and activate the contract and call for the help of the Dark Saintess.

Then, that night, the bug cart appeared in the secret room of the research institute along the path of the previous time.

This is a specially built secret room, designed to prevent anyone from discovering the connection between the White Dragon Empire and the Undercity.

The two Undercity guards led Ryuichi and Erin into the car, and the bug cart immediately sealed the tunnel completely to prevent anyone from prying eyes.

After a series of long journeys, Ryuichi and the others finally arrived in the Undercity once again.

The Dark Maiden had already arrived at the terminal and waited, the complex machinery in her chest glistening with brilliant light, and the residents of the nearby Undercity were all fascinated by the light.

"Master, you're here!" said the Dark Maiden.

"You still call Brother Long, it's too awkward to call the master. As soon as the dragon heard the word master, his scalp tingled.

"Okay, Brother Long, let's go!" the Dark Maiden cried sweetly.

"Good!"

Ryuichi and Erin quickly followed behind the Dark Saintess.

The three of them came to the temple of the Holy Maiden, and in the middle of the huge empty building, = there was a huge sphere, all dark gold, and it was full of criss-crossing fine lines. And it's constantly rotating and splicing.

"Brother Long, what you mentioned earlier, I checked the knowledge of our core clan, and there is really a record of things about the mad demon plane. The Dark Maiden spoke.

"Any good news?"

"Yes. The Dark Saintess glanced at Erin, then at Ryuichi with an inquiring look.

"It's fine. Anything can be said to Erin's face. Long Yi said.

Erin was well aware that it was clear that the Dark Maiden was going to say something extremely confidential. Long Yi's words were obviously a great trust in herself, and she was grateful.

"So. I'll get straight to the point. In the age of giants, giants were keen to explore different planes and planets, and the mad demon plane was naturally one of them. The creatures of the mad demon plane are extremely strong, but they are far from the giants. And what really causes trouble for the giants is crystal poison. The giants believe that Crystal Poison is actually a very small micro-symbiotic that consumes the host's body and energy in a symbiotic manner. and forms a crystal nucleus within the host. If the host is very weak, the host will die before the crystal nucleus can condense. And if the host is strong enough. Then, after the crystallization nucleus, the crystal nucleus itself will give birth to a new consciousness, which will try to kill the host's consciousness and act instead of the host. And if the host is extremely powerful. Then the crystal nucleus will choose to be accompanied. Gain the protection of the host by strengthening the host's body. ”

As she spoke, the golden sphere transformed, turning into a crystal nucleus, into a host, demonstrating to the three of them what the Dark Saint had said.

"I remember that I was also attacked by monsters, and I was also poisoned by crystals, but there was nothing serious. Erin said.

That was when I was hunting monsters. Erin is poisoned by the crystal, and Azusa offers a spell. Help Erin detoxify while also getting the Crystal Nucleus Gauntlet.

"That's different, the crystal poison in you is not strictly a crystal poison. Only monsters from the mad demon plane, the big demon or above in your mouth, will carry the real crystal poison. What was infected at the beginning was just some toxins with crystal poison properties. "In the mad demon plane, the air is full of crystal poison. These crystals disguise themselves as the body's own cells, so when infected, they will not have any symptoms at first. At the same time, the crystal poison begins to devour biological cells and replace them with itself, so that people will not feel any pain at this time, but will feel high spirits and infinite strength. Depending on the strength of the organism, this process can last anywhere from a few days to several years. Once the engulfing process is over, the crystal poison will erupt in a short period of time, and the creature will completely crystallize within five seconds, and at the same time, it will condense the crystal nuclei in the body. The crystal nucleus will constantly try to strangle the original consciousness of a creature, that is the last chance of a creature, if the consciousness of that creature is strong enough, it may struggle down, but then it will be too late, and its own consciousness has already been destroyed and fragmented, in other words, it is crazy. ”

"That's why it's called the Mad Demon Plane......" Erin thought for a moment.

"It seems that this crystal poison is not a specialty of the mad demon plane?" Long Yi felt, it seemed to mean some kind of invasion of foreign creatures?

"Yes, the creatures of that plane were originally called demons, and the crystal poison came from another plane. Said the Dark Maiden.

"Okay, thank you for your science. So...... That's the second question. Long Yi said.

The Dark Maiden nodded, then patted the golden orb, and complex runes and formulas appeared above the orb.

"Even giants can't completely resist the erosion of crystal poison, so giants later invented a vaccine, and the success rate is 100% through vaccines to deceive the infection of crystal poison. At the beginning, the giant was also verified on humans, and it was also effective for humans. However, the way the vaccine is prepared is troublesome. Said the Dark Maiden.

"How troublesome is it?" asked Ryuichi.

"First of all, there must be a big demon, alive. ”

Sure enough, troublesome!

Originally, there were few big demons in this world, and after countless hunts, the only remaining big demons were also slaughtered, let alone alive. Moreover, according to relevant records, once the big demons are captured alive, they will immediately turn on the self-explosion mode, and there will be no grass within a radius of 100 meters, and even the dragon knights will be seriously injured, and it is not so easy to capture them alive!

"Is there any other way? Long Yi asked with a fluke mentality.

"It's gone. The Dark Saint said earnestly.

"Then it's troublesome, just the self-explosion of the big demon is enough to make people nerve-wracking, how did the giants make the big demons obedient in the first place?"

"Giants have countless ways to make the demons honestly obedient, but humans can't. ”

"How about mind control? Xiao Zi should be able to help. Ryuichi said, "Banshee's psychic attack should be effective against any sane creature. ”

"There will be some effects, but they will not be noticeable, or even as good as the freezing effect. But whether it is mental impact or freezing, it actually has no great effect. If you just make the big demon obedient, it's very difficult, but if you just don't blow yourself up by the big demon, the Dark City has a plan, but this plan is not mature, Brother Long, you need to find human scientists to carefully study a more mature plan. ”

"What is it?" said the dragon's eyes.

"Rapid neutralizer. "In the beginning, when we decided to use the crystal nucleus as a power source, we also encountered the self-explosion of monsters. So we invented a neutralizer to delay the monster's self-detonation. This technique can almost successfully delay the time for the monster to explode by half an hour. However, before this technique could be put into use, we already had an easier way to obtain crystal nuclei, so the development of neutralizers was suspended. I think that those intelligent human scientists should be able to use this to create almost a real neutralizer. ”

As she spoke, the Dark Maiden took out a small bottle from the dark golden orb, and the inside of the bottle was a red liquid. "This is the only test liquid that has survived. ”

Long Yi carefully took the red liquid and placed it in his private space. (To be continued......)
