Erin saluted the two princesses, then turned around and ran to Long Yi. Compared to chatting with these people, Erin liked more about training with Long Yi. The strong fragrance around her made her headache.

Seeing Erin go away, the two princesses smiled slightly at the same time and said to Pera: "Then we will say goodbye. We have a great time today. Please ask President Pera to cross our names off."

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

In the venue, a group of girls looked at each other, without any mood of chatting and laughing.

Pera had already hated her anger to the extreme, but there was no sign of her face.

"Okay, since the annoying man and woman have left, and the respected princess has also left, now we are the protagonists again! Come on! Let's indulge in it!"

Pera called on the girls to smile again, but not long after, the haze just now had been wiped out.

What happened today can be regarded as the decision between Erin and the past. After leaving the butterfly meeting, she felt that she became more relaxed. Although she was still a little confused, Long Yi saw confidence in the eyes of this girl for the first time.

Long Yi never expected that this girl named Pera would have such a huge influence on Erin. Just her decision with Pera could make Erin rebuild her confidence.

However, who can explain the human affairs clearly? Perhaps the only thing that affects a person is a small matter, the butterfly in the dream and the moon in the well, how many people can understand it without experiencing it personally?

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

Is this scene in class?

Long Yi was a little stunned.

Seeing Long Yi appear, Xiao Zi immediately threw down the book and smiled and walked over. Instructor Dingge looked at Long Yi with an angry face. Obviously, someone seemed to be coming at a very bad time.

"You bastard can't come late? Teacher Xiao Zi is telling us the critical moment!" Mentor Dingge's hair was gone, his dilapidated clothes disappeared, and his face was full of stubble. Strangely, he was not as sissy as he was.

"Have you delayed?" The honest man Long Yi discovered that he seemed to be coming, and it seemed that in the eyes of mentor Dingge, he was becoming a stumbling block to the development of the magic of the White Dragon Empire.

"No, Brother Long, we were just discussing a spell. Then I just used the truth to tell them. What they have been studying for three years is wrong." Xiao Zi said with a smile.

"Oh, I thought I was in the way! Since that's the case..." The honest man Long glanced at the researchers who were glaring around him and showed the most sincere smile, "Since that's the case, Erin's matter is over, let's go."

As soon as he finished speaking, the four researchers who were still glaring at the same time all changed into smiles.

"Ah? Isn't this a young and promising young Long Yi? We were all too focused just now and didn't notice that you are back? Are you thirsty, are you hungry, are you cold, are you hot? Look at you, just came back from the dance party, aren't you not changing your clothes? I guess you must not be full? You are going to take a break first, take a shower, have a meal, and take a nap. What do you think?"

The four researchers, the oldest ones are from Grandpa Long Yi, and the youngest mentor Dingge is from uncle. Each of them has a flattering face and is careless about his not pure flattery skills. He doesn't care about Long Yi's body being covered with goosebumps.

"Stop! Otherwise, Xiaozi, please continue to tell them, I'll go somewhere else first?" Long Yi felt that if the emperor saw that the researcher he had cultivated was like this, the emperor would definitely chop Long Yi first and then chop the four people.

It's so disgusting, so disgusting.

"Walk around? No problem! No problem at all! Come, take it! This is a pass that can be unobstructed at any location within the institute. This belongs to you, you can go quickly!"

Tutor Dingge directly stuffed the pass around his neck into Long Yi's hand, his eyes very obvious.

"Well, Brother Long, I actually want to hear it too." Erin looked at Long Yi and said. Although Erin only heard a little, she felt very interesting, so she wanted to know what Xiao Zi was saying to these researchers.

"Haha, welcome! We welcome every talented person to join us!" Dinger was extremely excited because he knew Erin's talent too much. It was because Erin's unique insights into a certain spell formula that directly led to a milestone leap in the institute! Of course, in order to protect Erin, the institute only claimed to the outside world that this was their achievement, but everyone knew in their hearts that the original formula came from Erin!

In comparison, Long Yi was a little pitiful.

Hello! What's the disgusting look on you bastards? Although I have not studied magic well, I can beat you! If you don't agree, I will beat you all into pig's heads!

He shouted and cursed in his heart, but did not take it seriously. Long Yi still smiled and wandered around with his pass.

The Royal Institute is divided into several areas, including the Institute of Spell, Mechanical Research, and New Energy Research Institute. Each institute also has branches, and there are various small institutes under it. The pass on Long Yi’s chest is second only to the top-level high-level pass, and you can go to most areas.

He wandered around aimlessly, feeling the most expensive area of ​​the entire White Dragon Empire.

Any technological research and development in any world is a bottomless pit for money. Once successful, it will benefit generations. If it is not successful, then the money will be burned endlessly. The extent to which it can be burned depends on the emperor's courage. In this regard, the White Dragon Empire has always done a better job. The emperor attaches more importance to the research on new technologies than the next generation, and the capital invested is getting bigger and bigger.

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

"Huh? You? Are you? Who? Who is here? Ah! Bajie! You are Long Yi from the Bajie team!" An old man's voice sounded on one side. Long Yi turned his head and saw that under the dim street light, there was a face that seemed familiar.

"Director of Madberg?" Long Yi recognized the old man, who was the director of the Crystal Branch of the New Energy Research Institute, Madberg.

"Hahaha! It's really you! I looked at you from a distance, and I felt like you, but I didn't expect it was really you!" said the dean of Madberg happily.

"Haha, Dean, you still remember me!" Long Yi looked at the energetic old man opposite, but felt something was wrong. Simply put, the old man's eyes seemed a little too bright.

"Are you looking at me in the eyes?" said the dean of Madberg, with a serious smile.

"Yes, your eyes feel a little special." Long Yi carefully selected the adjective.

"Haha, you guys are so embarrassed. This is my new invention!" said the dean of Madberg, blinking, and the strange light in his eyes disappeared.

"What is that?" Long Yi was very surprised.

"This is night vision glasses! It is made by your discovery!" said the dean of Madberg excitedly.

"My discovery?"

"That's right, didn't you discover the misunderstandings in the research of crystal nuclei! After I went back, I immediately tried my best to get new crystal nuclei within an hour. We carefully studied it and found that the crystal nuclei did not die for more than an hour, but entered a dormant state. If the conditions were right, it could still be reactivated. In the next time, we were all thinking about how to solve the problem of re-restoreing the crystal nuclei!" The dean of Madberg was still very excited. Obviously, he might not have too many listeners to listen to these words.

"Then what?"

"Then we succeeded! We reactivated the crystal nucleus, and we also developed how to maintain the activity of the crystal nucleus. We also developed a lot of fresh gadgets based on the different characteristics of the continuous crystal nucleus!"

The dean of Madberg pointed to his eyes. Long Yi finally saw that on one side of the eyeball, an extremely tiny crystal nucleus was implanted into the eyes. When needed, the crystal nucleus would extend a thin film to cover the eyeball and enhance people's vision.

"I, an old guy, had poor eyesight at night. With this thing, I can walk with peace of mind again!"

"With this thing, maybe you can make a batch of Dragon Knight helmets with far-sighted function." Long Yi said.

"Looking far away? What is that?" asked the dean of Madberg in confusion.

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

Wait, why don’t I build a telescope to sell? Why am I so stupid? This thing is absolutely a huge profit! Sell it to the army, and all the commanders have one, the general has a gold special edition, and his own signature is also on it!

Damn it! This is a fucking opportunity to get rich!

"Ahem, this is just my idea. I haven't made a big plan yet. When I look back and figure it out, I'll tell you again!" Long Yi said without hesitation.

"Okay! You must tell me! Alas! It's better to be young! There are so many ideas. We old guys are not good enough! If it weren't for you, we really don't know how long we would have to struggle!" The President of Madberg suddenly sighed again.

"Director, you are serious, I'm just blind." Long Yi said modestly.

"Ah! By the way, the archaeological team just sent a batch of ancient heritage. Are you interested in going to see it together?" said the dean of Madberg suddenly.

“Ancient heritage?”

"Yes! Ancient heritage!" (To be continued, please search for astronomy, novels are better, updated and faster!
