Erin saluted the two princesses, then turned and ran to Ryuichi's side. Compared with these people's small talk, Erin prefers to train with Ryuichi, and the strong fragrance around her gives her a headache.

Seeing Erin go away, the two princesses smiled at the same time, and said to Pella: "Then we will also leave, we have a lot of fun today, and ask President Pella to cross out our names as well." ”

After saying that, the two princesses left directly surrounded by the guards.

In the venue, a group of girls looked at each other, completely in no mood to talk and laugh.

Pera hated it to the extreme, but there was nothing on her face.

"Alright, now that the obscure man and woman are gone, and the esteemed princess is gone, now we are the protagonists again!

Pera called, and the girls reluctantly regained their smiles, but it didn't take long for the haze to be cleared.

What happened today can be regarded as a complete decision between Erin and the past. After leaving the Butterfly Club, she felt more relaxed. Although there was still some confusion, Long Yi saw confidence in this girl's eyes for the first time.

Long Yi didn't expect that this girl named Pera would have such a huge influence on Erin. Just the decision with Pera was able to rebuild Erin's self-confidence.

However, who can say clearly about human affairs? Perhaps it is only a small thing that affects a person, the butterfly in a dream. The moon in the well, if you don't experience it, how many people can understand?

Return to the Royal Academy of Spells. Tutor Dinger and three of his colleagues were sitting in a row, notebooks in their hands, taking notes. In the front, Xiao Zi is holding a book in one hand and writing something on the small blackboard with the other.

Is this scene in class?

Long Yi was a little dumbfounded.

As soon as he saw the dragon appear, Xiao Zi immediately threw down the book and pulled over with a smile. And Mentor Dinger looked at Long Yi with an angry face, obviously. Someone seems to have come at a bad time.

"You bastard, can't you come late?Mentor Xiaozi is telling us about the critical moment!" Mentor Dinger's messy hair is gone, his tattered clothes are gone, and his stubble is gone. Oddly enough. There's no girliness yet.

"Delaying you?" "Honest man Long Yi found that he seemed to have really come at the wrong time, and it seemed that in the eyes of Mentor Ding, he was becoming a stumbling block to the development of spells in the White Dragon Empire.

"No, Brother Long, we were just talking about a spell just now. Then I casually tell them the truth. What they studied for three years was wrong. Xiao Zi still said with a grin.

"Oh, I thought I was in the way!...... "Honest Dragon smiled most sincerely, glancing at the glaring researchers around him, "In that case, Irene's affair is over, let's go." ”

As soon as the words fell, the four researchers who were still glaring angrily just now all changed their smiles almost at the same time.

"Ah, isn't this a young and promising young man? We were all too focused just now to notice that you were back? Are you thirsty, hungry? It's not cold, it's not hot. Look at you, you just came back from the ball? Didn't you change your clothes? I guess you haven't eaten enough? What do you think, go and take a break, take a shower, have a meal, and take a nap?"

The four researchers, the oldest of whom were all from Long Yi's grandfather's generation, and the youngest Dinger tutor was also from his uncle's generation, each of them had a flattering face, splashing his own not pure sycophant skills without paying attention to Long Yi's goosebumps.

"Stop! Otherwise, Xiao Zi, you continue to tell them, and I'll go for a walk elsewhere first?" Long Yi felt that if the emperor saw that the researcher he had cultivated so much money actually looked like this, the emperor must have cut Long Yi first, and then cut those four people.

It's disgusting, it's disgusting.

"Walk around, no problem! No problem at all! Come, hold! This is a pass that can be used anywhere in the institute, this is yours, you can go!"

Mentor Dinger directly stuffed the pass around his neck into Long Yi's hand, and his eyes were obvious.

"That, Brother Long, I actually want to hear about it too. Erin looked at Ryuichi and said. Although Erin had only heard a little bit about it just now, she was also very amused, so she wanted to know what Xiao Zi was talking about to these researchers.

"Haluha, welcome! We welcome everyone who has talent to join us!" Dinger was excited, because he knew Erin's talent too well. Of course, in order to protect Erin, the research institute only claimed that this was their achievement, but everyone knew in their hearts that the original formula came from Erin!

And in comparison, Long Yi is a little pitiful.

Hey, hey, you bastards, what's the matter with those disgusted eyes? Although Lao Tzu is not good at spell research, he can fight! If you don't accept you, Lao Tzu will beat you all into pigs' heads!

I scolded a few times in my heart, but I didn't take it seriously, Long Yi still smiled, and walked around with his pass.

The Royal Academy is divided into several areas, including the Spell Research Institute, the Machinery Research Institute, and the New Energy Research Institute. There are also various branches in each research institute, and there are various small research institutes under it. The pass on Ryuichi's chest is second only to the top premium pass and provides access to most areas.

He wandered aimlessly, feeling the most money-burning area in the entire White Dragon Empire.

The research and development of any technology in any world is a bottomless pit that burns money, and once successful, it will benefit all generations. If it doesn't work, the money will burn endlessly. How far it can be burned depends on the emperor's courage. In this regard, the White Dragon Empire has always done a relatively good job. The emperor paid more and more attention to the research of new techniques from generation to generation, and the capital invested in it became larger and larger.

Therefore, for these emperors, Long Yi still has an instinctive favor.

"Huh, you, who are you, who's coming, ah, yes, Bajie! You're Long Yi of the Bajie team!" An old man's voice sounded on one side, and Long Yi turned his head to see a seemingly familiar face under the dim street lamp.

"Dean Magdeburg?" Long Yi recognized this old man, it was the director of the Crystal Nucleus Branch of the New Energy Research Institute, Magdeburg.

"Hahaha! It's really you! I looked at you from afar, and I felt like it was you, but I didn't expect it to be you!" said Dean Magdeburg happily.

"Ha Luha, dean, do you remember me!" Long Yi looked at the energetic old man opposite, but felt that something was wrong. To put it simply, this old man's eyes seem to be a little too bright.

"You're looking me in the eye, aren't you?" said Dean Magdeburg, smiling gravely.

"yes, your eyes, it feels a little special. Long Yi carefully chose the adjectives.

"Ha Luha, you kid is awkward, this is my new invention!" said Dean Magdeburg, and in the blink of an eye, the strange light in his eyes vanished.

"What's that?" Ryuichi was strange.

"It's night vision goggles! it's something you've discovered!" said Dean Magdeburg excitedly.

"My discovery?"

"That's right, didn't you discover the misunderstanding of crystal nucleus research! After I went back, I immediately tried every means to get a new crystal nucleus within an hour, and we studied it carefully, and found that the crystal nucleus was not dead for more than an hour, but entered a dormant state, and if the conditions were right, it could still be reactivated. We're all going to be figuring out how to get the crystal nucleus back alive!" Dean Magdeburg was still very excited, and it was clear that he probably didn't have much of an audience to listen to.

"And then?"

"And then we succeeded! We reactivated the nucleus, we figured out how to keep the nucleus alive, and we came up with a lot of new gadgets based on the different properties of the nucleus!"

Dean Magdeburg pointed to his eyes, and Ryuichi finally saw that on the side of the eyeball, there was an extremely tiny crystal nucleus implanted in the eye. When needed, the crystal nucleus extends into a thin film to cover the eyeball and enhance one's vision.

"My old guy used to have poor vision at night, but with this thing, I can walk with peace of mind!"

"With this thing, we may be able to make a batch of dragon knight helmets with promising functions. Long Yi said.

"What is that?" asked Dean Magdeburg, puzzled.

Only then did Long Yi remember that in this world, optical techniques were still in the enlightenment stage!

Wait, why don't I build a telescope and sell it? Why am I so stupid? This thing is an absolute profit! Sell him to the army, and all the commanders will have one, and the general will have a gold special edition with his own autograph on it!

Damn! This is a fucking chance to make a fortune!

"Ahem, this is just an idea of mine, I haven't thought about it yet, when I figure it out later, I'll tell you again!" Long Yi said without hesitation.

"Okay! You must tell me! Hey, it's better to be young! There are so many ideas, we old fellows can't do it! If it weren't for you, we really don't know how long we would have to struggle!" Dean Magdeburg suddenly sighed again.

"Dean, you're serious, I'm blind. Long Yi said modestly.

"Ah, by the way, the archaeological team has just sent a batch of ancient heritage, are you interested in going and seeing it together?" said Dean Magdeburg suddenly.

"Ancient legacy?"

"Yes, Ancient Legacy!" (to be continued......)
