I am doing scientific research in Douluo

"There is such a function! Isn't it possible to cheat openly! And you don't have to worry about someone finding out!" Xu Sanshi was shocked, he really didn't expect Xu Ling to make such a thing.

"Who thinks the same as you? It's specially used for cheating! I made it for the purpose of communicating with Xue Nu at any time. Only you want to cheat!" Xu Ling's face was full of black lines, and Xu Sanshi couldn't wait to put it on. Xu Sanshi's face was swollen!

"Okay, okay, I was wrong! But our purpose this time is to get more metals, right? In order to get metals, Nannan and I...!" Xu Sanshi made a gesture of wearing a ring, The intention was obvious, that is to ask Xu Ling to make a pair of rings for them both.

Xu Ling said with a dark face, "No!"

Seeing what Xu Sanshi was going to say again, he immediately interrupted: "Not now, I'll do it tonight, and I'm sure there will be one tomorrow!"

Xu Sanshi jumped up happily when he heard that, took Jiang Nannan's hand, and began to study which finger would look better on him.

Xu Ling took out the materials he bought in the morning, and barely made a few conductive rings. They had no other functions, and they were not even very good-looking, but everyone could use specific techniques to make waves, causing other people's rings to vibrate , everyone understands what she wants to express according to the vibration frequency.

Everyone went to register the next day, and there was no registration fee for this competition. They just looked at the three-star soul instructor badges on everyone's chests, simply recorded their names, and issued a sign.

The official competition will start three days later, and the entire competition will last for 18 days in total. The first [-] days are for each basic checkpoint of the subdivision of soul guides, and the next three days are for the competition of making soul guides, because The production of soul guides does not take longer than the previous individual competitions, so the competition has a duration of three days.

Xu Ling and the others went back after signing up. It happened that they could use the three days before the competition to learn the vibration code pairing code, and then they could choose the answer based on the vibration code.

Xu Ling didn't perfunctorily teach with simple vibrations such as one vibration, two vibrations, etc. just because it was a competition, but taught a set of slightly esoteric vibration frequency code words.

This set of vibration frequency code words is actually very simple, and it is only used for some simple daily conversations, but it can already let everyone know what the other party wants to say purely by vibration frequency.

Xu Ling first wrote a very simple comparison table, what frequency represents what word, and then let everyone memorize it, and then practice more, Xu Ling flicked the ring to send out the frequency and said some instructions .

For example, the wave Xu Ling sent to the ring just now meant to quickly come to my room jihe.

It didn't take a minute, everyone came to Xu Ling's room one after another, and after seeing that everyone could probably remember these, they threw out a relatively complicated comparison table.

Xu Sanshi took a look and fell back directly, pretending to be dead.

"Xu Sanshi, what are you doing!" Xu Ling's face was black.

"I still want to ask you why!" Xu Sanshi lifted his feet up, jumped up, and stood up from the ground.

"You say we are simply cheating in the exam, why do we have to learn such a rare thing!" Xu Sanshi pointed to the thick comparison table that Xu Ling had just thrown out on the table, with an aggrieved expression on his face.

"I didn't tell you to learn it now. It's already the third day, and the exam is tomorrow. What should I do?" Xu Ling looked at Xu Sanshi speechlessly.

Hearing Xu Ling's words, Xu Sanshi instantly smiled with surprise, and patted Xu Ling's shoulder with an expression that I knew Xu Ling was not such a person.

"No, I can't stand it. Although you are not allowed to learn it now, you must learn it later and remember the above information. What~ do you think I will waste my efforts to get a useless ring!" Xu Ling looked at it. Xu Sanshi said, You underestimated me.

"Don't think that I don't know what you're thinking, you think I have to force you to learn it! But we must master a method that others don't know and can guarantee communication. Even if others know it, they can't eavesdrop!"

"Don't think this is useless! Let me tell you, did everyone's soul guides be concealed in the second level? But I can tell you that the vibration of the vibrating ring between me and Xuenv was not shielded! That's why I can safely let Xue Nu stay in the inn to wait, otherwise you think I would be willing to let Xue Nu stay in the inn alone!?"

Xu Ling became serious as he spoke.

"We don't know what we will experience in the future, but I think we, the Seven Shrek Monsters, are one. At least we need to ensure everyone's safety before we get married." Xu Ling said while holding the ring in his hand.

"For example. If Xu Sanshi, you are kidnapped by an evil soul master, you can tell us your location through this simple frequency, so that we can provide effective support, right! For example, you tell me where you are How many evil soul masters and how many levels are there? After we have prepared, we can ensure the safety of you and everyone. In this way, everyone can avoid unnecessary losses and injuries as much as possible! So don’t think that I took out this book. To embarrass everyone, no! I just think we need such an alternative communication method, so as to ensure everyone's safety!"

After listening to what Xu Ling said, everyone was thoughtful, with expressions of sudden realization on their faces.Beibei stared at the ring on her hand, as if thinking about something.

"Xu Ling, I think our Tang Sect needs to have such a ring. At the very least, everyone in the Tang Sect that we believe to be trustworthy needs to be equipped with a ring so that everyone can learn from it, so that our Tang Sect will also be safe." !"

After hearing what Beibei said, Xu Ling thought it was okay, so she nodded, indicating that it was okay.

The assessments for the first three days were all knowledge-based assessments that did not require hands-on work. It happened that all members of Shrek were on stage to conduct a large-scale "code code" exercise.

The first day is the most basic [Metal Identification] assessment. Everyone came to the assessment site together. Because there are many people, the examination is conducted in batches. By the way, it can also prevent cheating, because each time the assessment questions will be randomly selected. Metal, and after the assessment, the results came out soon, which made Xu Ling feel that the Sun Moon Empire did a good job in this aspect!

Xu Ling and the others were also divided into two waves for the exam, but fortunately, the two waves had two senior soul engineers, Xu Ling and Huo Yuhao, sit in and transmit the answers, so the seven Shrek people didn't panic, and it ended smoothly. In this assessment, the results are all full marks!

The next day was the assessment of [Core Formation Recognition]. Everyone was lucky enough to be assigned to the same examination room. This time Xu Ling asked Huo Yuhao to transmit the answers, because Huo Yuhao was better than Xu Ling in terms of basic knowledge.Huo Yuhao's focus is on improving soul guides, and he knows more about formations than someone like Xu Ling who only wants to create new and innovative soul guides, and he understands them better.

The third day was the assessment of [Looking at the Soul Guidance Device]. This time, the seven Shrek people were not so lucky. Xu Ling, Huo Yuhao, Xue Nu, and Bei Bei were assigned to the same exam room, and the others were assigned to the same exam room. So when the final results came out, only Xu Ling and Dong'er barely passed the test!Xu Sanshi and Jiang Nannan did not pass the test.

It has to be said that it can be seen from here that Dong'er has really learned a lot from Huo Yuhao, and has a solid basic knowledge of soul tools.
