After settling Freya, Chen Rui returned to the bedroom and started training in the training ground. Since Freya was still under the control of Sabrinas [Soul Shackles], there were many things that he couldnt disclose. It was to himself and also to protect Freya.

To really let Freya and Kia regain freedom, he must remove the [Soul Shackles]. The possibility for Sabrina to remove it by herself was zero. Asking her to remove it would be even harder, and it might even cause suspicions. The best way was to kill Sabrina. Yet, that was very difficult. Even without alerting everyone else, with Chen Ruis current strength, he couldnt do it if they fought head-on.

Now that Azgalor and Manu hadnt returned, he must make good use of Sabrina and Izolas bet and contradiction. Together with the controlled Fatilu, it should be a key entry point.

The next day, Chen Rui came to the blue house in the Devouring Hall. Sabrina had been waiting there for a long time.

Sabrina didnt say any nonsense. She took Chen Rui to the end of the Crystal Valley. The road was getting narrower, and the sky above was becoming one line. The place was very dangerously steep. After walking through the passage, a cave finally appeared in front of them.

No one dared to stop Sabrina along the way, but Sabrina was stopped at the entrance of the cave. These were two Beelzebub Royal Family, both of them were middle-stage Great Demon Kings. Beside them, there were a team of crystal men. Besides, all of them were leader-level, Great Demon Kings. It seemed that this place was guarded heavily.

One had to know that even if an estate only had a few Great Demon Kings. For example, in the Dark Moon Estate, only Shea had reached this level.

Sabrina snorted, Guli, Phil, both of you dare to stop me?

Guli frowned, Madam Sabrina, please forgive us. Madam Izola ordered no outsiders be allowed to enter.

Outsiders? Sabrinas eyes flashed coldly. The surrounding temperature suddenly dropped. The water on the ground began to freeze into ice.

Phil quickly said, Dont misunderstand, madam. The outsider is regarding the Great Demon behind you. I believe madam also knows that this part of our responsibility. If youre in control, well still faithfully execute this order.

The chill from Sabrinas body slightly reduced, then she said coldly, Izola and I have set a challenge date. This is the challenger. I brought him to have a look at the situation today. It shouldnt be a problem right? Guli still insisted, Thats non-compliant, madam. No matter whether he is the challenger or not, he cant enter the Mystic Valley!

If madam, you want to go in, please feel free. If this Great Demon can get permission from Madam Izola or Master Toto, itll obviously be fine as well. However, if you dont have permission, please dont make it hard for us. Phil said politely, but he was still conveying the same thing.

Sabrina didnt expect to be stopped by the door. She felt embarrassed in front of Chen Rui. The killing intention on her face could even be felt over her veil.

Guli and Phil looked at each other, and they saw the helplessness in each others eyes. However, the current master of the Mystic Valley was Izola. If they let both of them in, their ending might be even worse. They started withdrawing slowly. As they waved their hand, the still crystal men started to move their joints and approached.

The strength and speed of the crystal men were relatively weak, but their defense was extremely high, especially magic defense. Besides, they had no fear of death, But they had relatively weak combat power. They couldnt be compared with the [War Puppet] of the Lust Royal Family. Guli and Phil didnt really want to fight Sabrina. They just wanted to delay until someone in-charge came to resolve the dilemma.

A magic steel armor appeared simultaneously on Guli and Phil. Guli seemed to be a mage as he was chanting spells quickly with his mouth. Then, a huge translucent air shield appeared in front of him and Phil. They were obviously only defending instead of attacking.

Sabrina intended to show her authority, so she didnt rush to attack. She waited for them to complete all that, then her figure instantly appeared in front of them. Chen Rui felt that her figure had suddenly become four or five. At the same time, a high-speed beating sound came from the crystal mens bodies. The violently trembling air shield lasted only a few seconds, then it was demolished. Demon Emperor and Great Demon King were indeed an insurmountable gap.

Chen Rui could barely see Sabrinas movements at the full extent of his eyesight. Oftentimes, he could only rely on [Analytical Eyes] to judge her position. He couldnt help being shocked. The moment that Guli and Phil were in crisis, someone suddenly shouted, Stop!

The intensive beating stopped and Sabrinas figures returned to one. When she returned to Chen Ruis side, her face wasnt red nor was she breathless. She looked like nothing had happened. The body of those durable crystal men on the opposite had many cracks. The crystal men were quite similar to the crystal dragon where their recovery was very slow after being damaged. This level of damage most likely needed to take a very long time to recover.

An old-looking dark goblin with grey hair came out from inside. Although he was only a Higher Demon, Sabrina showed considerable respect. She nodded, Master Toto, I havent seen you for a long time.

Chen Rui found out that the dark goblin was the master craftsman of the Mystic Valley. If the dark elf commander, Norris was equivalent to the chief executive officer, then Master Toto was the technical director. Besides, in the Mystic Valley, the latters status was higher than the former.

Madam Sabrina, please dont make it difficult for Guli and Phil, they are only doing their job. Besides, no outsiders are allowed to enter is a rule set by you back then. Toto bowed slightly to Sabrina and glanced at Chen Rui, Ive heard the incident between two madams. Is he the challenger seven days later?

Yes, Master. Sabrina laughed, Master Arthur is the most promising person in the world to become a grandmaster.

Trio-specialized, magic circle genius? Totos tone seemed to be somewhat indifferent. Its just that the Mystic Valley isnt a Mechanic Alliance. Perhaps this genius doesnt have much use. Besides, if he fails in the challenge, he might lose his life. Then, he will be useless even if he has great potential

However, if you insist on participating, then come in and take a look. With Master Totos permission, Guli and Phil naturally dared not to stop him anymore. In fact, if it wasnt for Sabrinas mercy just now, even with the crystal men, they couldnt stop her.

Sabrina and Chen Rui followed Master Toto into the cave. After passing through a few dim and complicated byways, Chen Rui felt that the scene suddenly lit up before his eyes. The scene had completely changed. The cave was just an entrance. After passing it, it was a huge space in the open air.

It was completely different from the mysteriousness that he imagined. It was full of bustling people like a huge factory. What made Chen Rui surprised was a huge object in scaffolding in the distance. It resembled a humanoid form with a dark red shell.

Is it Gundam? Am I seeing it right? Red colour, horn, 3x speed [1] Could it be that the captain also cross-overed?

Chen Rui was almost blinded. He rubbed his eyes and looked carefully. This humanoid was still quite different from Gundam. Master Toto saw his surprised look and said proudly, That is a giant puppet that is currently being tested. The giant puppet is built after the [War Puppet] of the Asmodeus Royal Family. If the test is successful, even ordinary demons can use this puppet. At that time, a muffled sound came and the ground was shaking slightly. Master Toto frowned, That should be the power magic cannon test. There are still some problems in terms of control, but its power is very strong. It seems that the defensive magic circle around the experimental site must be rebuilt.

Upon witnessing, Chen Rui finally understood that no matter in which world, the passion for creation and invention would never be exhausted. The Mystic Valley before his eyes was obviously a research center where a group of scientists gathered in the Demon Realm. Certainly, the main purpose of their research was for war.

Master Toto took both of them to another experimental site, then he proudly introduced several research results: the previous Gundam, artillery, and missiles are related to the mechanics. Now, its about biotechnology.

Chen Rui shuddered to see that these crazy scientists attempted to avoid the long hours of research. Instead, they used potions, magic circles or even cross-breeding with demonic beasts to induce direct mutations on demons. The mutated demons only had crazy fighting instincts with no fear nor pain while their combat power increased several times, tens of times or even more.

This mutation test wasnt very successful at present as the control rate and survival rate werent high. Also, most test subjects would die in a short period of time after exhausting their vitality to fight. Once this kind of experiment achieved a certain success, then an army with terrifying combat power would be established.

With this kind of mutant armys combat power, an ordinary powerhouse could hardly retreat unscathed unless they reached a certain peak.

All in all, that was a rather terrifying experiment. In this lab, Chen Rui also saw a somewhat familiar scene. The test subject would receive a self-explosive potion. After consuming it, their eyes, ears, nose and mouth would emit a dazzling silver light. Then, their entire body would burst apart. This kind of potion could be used in suicide bombing, and it could also be used on some spies to prevent the disclosure of secrets.

Chen Rui remembered that he had seen a similar situation at Mountain Xilang. The exhibitor was the deputy leader of the mining office, Connor. Although he was a minor role, he tricked Athena to fall into the danger of the main pit and tempted Chen Rui to save her. He even destroyed the magic barrier and finally self-exploded. He was exactly the same as these tested demons, but his strength wasnt as good as the test subjects. He seemed to be the previous batch of test recipients. Chen Rui just realized that Connor turned out to be part of this force!

Master Toto was right. Even if Chen Rui was a mechanic genius, he really wasnt of much value in this type of research institute.

This huge force already had top-level fighters. If the researches of the Mystic Valley succeeded and put into practice, then it would definitely erupt fully when it reached a certain level. By then, the Demon Realms situation would most likely have earth-shattering changes.

Chen Rui wasnt sure if the fallen royal families of Beelzebub and Leviathan would rise again, but he could be sure of one thing: that the entire Demon Realm would fall into a horrifying war. Since Im already here, for myself, my loved ones, my friends and for the hard-won peace protected by a woman, I have to do something.

It seemed that Crystal Valleys mission was far more complicated and difficult than he imagined.

No matter what world, the passion for giant robots never dies! Why not Gundam 00!!!!
