Chen Rui only said three "ideas", and he changed Master Toto's attitude towards him.

First, this Gundam ...... Eh, puppets, can you consider designing and shiyan separately by function type? such as defense, attack, speed, and can it be transformed into the form of a certain magical beast to facilitate combat or marching?

Second, the missile...... No, can the firing of the Crystal Cannon have a tracking function attached to it to lock onto the target?

Third, although the magic crystal cannon has poor mobility, it can design a defensive object that can move freely like a carriage, and equip the magic crystal cannon to become a mobile attack fortress......

Master Toto is a pure jishu stream, shameless to ask, quickly took a pen, and asked while recording, like a little reporter with the team. Although Chen Rui is a pure layman to machinery and the like, those whimsical "ideas" have frightened Master Toto - jishu is not easy to learn, but creativity is a natural inspiration, and plagiarism can't steal it (someone's shame).

After some discussion, under Chen Rui's creativity and the "contribution" of a few small physics knowledge, Master Toto, whose eyes were shining, no longer questioned the word genius, this is the real all-round genius, and it is the same in any field.

Saprina originally just wanted to use the relationship between the crystal dragon and Chen Rui to win the challenge, but she didn't expect Chen Rui to really rely on his ability to win the approval of the most prestigious master craftsman in the Valley of Secret Demons, maybe he could really win at that time. She secretly gave Chen Rui a thumbs up, and when she saw the two talking speculatively, she walked away to the side so as not to disturb her.

After learning that Chen Rui was also born in the wild road and was not a master disciple of a "famous and decent" family, Master Toto, who was originally born in the "evil faction", had a better impression of Chen Rui, but it is one thing to have a good impression, and it is another thing to challenge.

Chen Rui's opponent this time is Norris, the leader of the Valley of Secret Demons, that is, the dark elf who killed the original leader Spanda in the last challenge, and the challenge of the Valley of the Secret Demons is not about combat power, but about the content of a certain research.

The "specialty" of the original leader Spanda is the secret art of beast control and mind domination, which belongs to the "biotechnology" talent, and Norris broke through the wheat with the tip of a needle, defeating him in Spanda's strongest field, and finally Spanda died, and Norris ascended to the throne without dispute.

"Master Toto, can you tell me what the challenge is?"

Toto's answer surprised Chen Rui a little, the scope can be "mechanical" or "biological" research fields, the specific content is not limited, judging from the situation of the last challenge, it should be decided by the challenged. Norris's challenge to take the throne was to lock the two and a beast in a closed magic circle, and use psychic domination, mental power, or various magic and secret techniques to control the beast to attack each other.

The rule is that you can't kill the beast, you can't attack the opponent directly, and whoever dies first loses, so this kind of challenge is also called a deathmatch.

The Beast is the highest research achievement in the Valley of the Secret Demons, and is a terrifying creature that has been transformed into a half-demonic and half-beast, with a bloodthirsty and manic personality and quite strong combat power. At present, it is only a half-finished product, and it is extremely difficult to control, even if the beast control technique or mind control technique reaches the top level, it is difficult to control it.

In that duel, Norris and Spann used all their skills to move the heartstrings, and in the end, under Norris's control, the beast tore Spanda to pieces, and Norris won the victory of Zuihou.

Chen Rui was secretly frightened: This kind of challenge is not a real battle between the two, but the cruelty is still excessive, it is the same in any field, the king is defeated and the fittest survive.

"Norris is proficient in dark magic and curses and mind control mysteries, I guess this challenge is likely to use the content of the previous time, you have great potential to become a grandmaster, but you have a specialization in magic, and this aspect is definitely not his opponent. I suggest you don't participate in the challenge, you can come directly to the Valley of the Secret Demons, and I will appoint you as the deputy chief craftsman!"

Master Toto has a good intention, mainly because he can't bear to let this future grandmaster die at the same time as a talent with great "scientific research" potential, and the position of the deputy chief craftsman can be regarded as a thirst for talent, you must know that Horford, the dual-line proficient master brought by Izola, is only an ordinary level of "project leader", like Chen Rui, who is above 10,000 people under one person, and there is no other. ,

Chen Rui couldn't really stay here as a mad scientist, so naturally he wouldn't accept this kindness, but he asked quietly: "Master, if these shiyans succeed, the entire demon world will be turned upside down, and war will break out at that time......

"Yes!" Master Toto's eyes lit up, "Yes, when the time comes, these new weapons will be able to come in handy! They will definitely be able to cause unexpected lethality! Even the Demon Emperor may be consumed to death! This is simply a great success of epoch-making significance! My name will definitely be recorded in the annals of the Demon Race! haha......"

Chen Rui knocked on the side and said a few more words, but it made Master Toto more and more excited, completely immersed in his great longing to be worshiped by future generations. Chen Rui finally understood, this master Toto belongs to the fanatic type, and it is more difficult to persuade him to change his idea of becoming famous in the "history of science" than to persuade a demon tiger to become a vegetarian - whether his brother's name is immortal or stinking for thousands of years, he can become famous, as for maintaining the peace of the universe, go to his sister's.

This "reminder" made Master Toto look at the future deputy chief craftsman more pleasantly, and took him on a tour for a while, and Zuihou Sapurina left the Valley of Secret Demons with Chen Rui with satisfaction.

Saprina saw that Chen Rui was silent along the way, thinking that he was terrified when she learned the cause of Spanda's death, and comforted: "Don't worry, master, today we are mainly trying to let you have a general idea in your heart. As it happens, I saw that you were quite good at the big golems, and you only need to ask Lord Jacob to help you develop challenges related to this aspect, and you can win safely. ”

"Madam, there is no need to change the content...... Chen Rui shook his head, a puppet or something, it's just a nonsense in the sky and the sky, if you really want to compare, it will definitely not work, even if he has recorded a lot of relevant data with in-depth analysis, but whether it is biology or that kind of mechanical aspect, it is not something he is good at, even if it is in-depth analysis, he can't really understand it for a while, and naturally it can't withstand scrutiny.

On the contrary, the most likely challenge item is a little promising, and I don't know if that kind of wild beast can communicate with the eye of analysis, but judging from the situation depicted by Master Toto, the wild beast should be a fighting machine that only has the killing instinct left, and the possibility of communication is extremely small. The God-Eater Mask should be able to turn the beast into a puppet, but the number of puppets has reached the upper limit of two, and Fatillu will definitely not be able to give it up, so he can only abandon the pawn Snod, who is far away in the territory of the Red Nether. It's just that the puppet must be masked on the face when performing the puppetry, so that the God Eater Mask will be exposed. Now there is only one method that is more reliable, and that is to comprehend the power of the black realm of the self-asura, which has control attributes, such as manipulation, chaos, etc.

"The content has not changed?" Saprina was taken aback, Chen Rui was from Nightmare Valley, and he was deeply valued by his uncle Manu, if he died in the Valley of Secret Demons because of her, I am afraid that Manu would never give up.

"I'm going to take a quiet moment and think about how I can help my wife win this challenge. ”

Sapurina didn't say it casually when she saw him, after all, this matter was at stake, and it couldn't be regarded as child's play, so she secretly wondered if this Master Arthur still had a powerful mind control technique?

Sapurina thought for a moment and said, "Okay, I won't interfere much, please leave everything to the master, and if you need anything, just bring it up." ”

"I was just about to tell Madame that I need to trouble Madame to raise some materials, the more the better, the sooner the better, I need to make a prop to meet the challenge in six days. ”

Most of the materials listed by Chen Rui are rare materials for making Lei Yin, even multiple copies, and some are spiritual energy transformation materials, anyway, the bamboo pole at this critical moment is not knocked in vain.

When Saprina heard the names of these materials, her brows furrowed slightly, but she didn't doubt it, because the challenge was related to Chen Rui's life. She thought about it for a while, and pointed out that there were one or two things that she was afraid would not be able to get together, which was already better than Chen Rui imagined, and I believed that at this time, Saprina would not be able to perfunctory him.

In this way, Chen Rui returned to Nightmare Valley, the effect of the grandmaster-level healing potion was indeed extraordinary, Freya's hand had basically recovered, but he still looked very restrained when he saw him, Chen Rui comforted a few words, and began to enter the laboratory to practice. ,

Seven days passed in a flash, and it was finally time for the challenge of the Valley of the Secret Demons.

As Chen Rui expected, Norris, as the commander, chose the content of the last challenge, which was the deathmatch that controlled the wild beast.

In the Valley of the Secret Demons, the crystal dragon Jacob came to the scene in person, as an arbitrator, on both sides were Sapurina and Izola, the people in the Valley of the Secret Demons are immersed in their work on weekdays, and it is rare to have such an exciting challenge, except for those who can't leave, the rest are all coming to see the excitement.

Norris is a close confidant of Izola, a dark elf with a mutated bloodline, whose strength has reached the level of the early stage of the Great Demon King, and from the analysis of the comprehensive strength value, he is a magic cultivator, which makes Chen Rui think of another Great Demon King Skye in the Dark Moon.

If it is a direct one-on-one battle, with Chen Rui's combat power and those attributes of demon resistance, he can easily kill Norris (of course, on the premise of exposing his strength), but the challenge now is not to fight directly, but to control the mad demon to attack the other party, and once he fails, his life is in danger.

From the point of view of strength, "Arthur" is only the first stage of the demon king level, and Norris is the first stage of the big demon king level, and he is proficient in the art of control, and he also has a record of defeating the original leader Spanda, so the chance of winning is much greater, and almost everyone is optimistic about Norris.

Norris glanced at Chen Rui and showed a cruel smile: "The first day of the Demon Realm, the master of the weapon, the person who is most likely to become a grandmaster? is that you yourself want to die, and after being torn to pieces by the beast, I see what you will do to become a grandmaster!"

Before Chen Rui could refute, a calm voice spoke: "Master Arthur, you just have to try, with me, you will be fine no matter whether you win or lose." ”

Norris's smile froze on his face, and it was today's arbitration that spoke, the strongest Demon Emperor in the Crystal Valley, the Crystal Dragon Jacob.

Is this still arbitration? "Blowing the black whistle" before it even begins!

Jacob doesn't care so much, Master Arthur is the key person in transforming the restoration of the magic array, and he is also his important servant in the future, there must be nothing to do, as for the win or loss of these two women, it is a matter of the dragon's ass!
