"Why is it fate with you?" Yi Cheng shook Dongfang Mo's hand away, "It seems like it means something else." "It's not what it used to be in the library, it's a seemingly enclosed environment, and the walls and floors look like they're made of particularly strong metal.

Dongfang Mo smiled: "It seems that you haven't even read the title of the book you are holding." ”

Yi Cheng was stunned for a moment, closed the book, and looked at the title on it......

"Servant Dongfang Mo Skills: Subtle Erosion, Subtle Infiltration, Clear Sound Enhancement, Clear Sound Perception"

Yi Cheng was silent and stared at the title for a long time......

"Is it your ability to control sound?" Yi Cheng asked Dongfang Mo such a question.

"Almost." Dongfang Mo nodded, "But my voice is not as simple as you think, I can use my voice to simulate the ability of any attribute." ”

Yi Cheng directly ignored the second half of Dongfang Mo's sentence, and once again turned to the analytical formula he had just read, which was the first of the four skills in this book, "Trick Erosion". This skill seems to be a very offensive skill, but it is actually a very valuable defensive skill.

Originally, Dongfang Mo was using his own energy to attract the ubiquitous sound energy in the air, relying on these energies to erode the enemy's entire attack. If you are in a noisy environment, just this one move can wipe out all those powerful big killer moves during the flight. Even in a relatively quiet environment, it can completely reduce the power of the enemy's ranged attacks to a certain extent.

If you can really master this skill, you will be almost invincible when dealing with enemies who use long-range attacks as their main means. Unless the opponent is too much better in hard power.

"I have to say, this move of yours is very powerful." After reading the previous introduction, Yi Cheng couldn't help but sigh, "I only cared about reading the analytic formula before, but I didn't notice anything else." ”

"Are you desperately trying to find a difficult skill that you can understand?" Dongfang Mo immediately understood her thoughts.

Yi Cheng nodded.

"That's not right, the skills with a high difficulty may not be suitable for you, and the skills with a low difficulty may not be easy to use. For example, among the active offensive methods I usually use now, there is a skill with an analytical difficulty of one by one. Dongfang Mo smiled helplessly, "But since you said that you can understand the analytic formula of sophistic erosion, then try to construct it!" I can give you a little bit of guidance during the build, but how to incorporate this move into your own abilities is your own business. ”

Yi Cheng nodded: "Then I'll start now." ”

Dongfang Mo didn't respond, but went to the side to find a place to sit down, closed his eyes and didn't know what he was thinking.

Yi Cheng didn't care about him anymore and began to build his own skills with a difficulty of nine .nine.

Dongfang Mo closed his eyes, firstly, in order not to embarrass Yi Cheng, so that he could calm down and build skills, and on the other hand, he ......

"Why do you feel this way?" Dongfang Mo was very puzzled in his heart, "Obviously, she is not a follower at all, let alone a person from which work, why do I feel that way for her?" ”

At that moment just now, Dongfang Mo suddenly had a special feeling in his heart that he couldn't say, as if he had seen a long-lost family member, and like a friend he hadn't seen for many years, as if he had seen those servants at that time...... It's the same feeling when you see those who now belong to DN.,Or servants like Horikita Suzune.。

The number of people Dongfang Mo has seen and the number of people he knows can definitely be regarded as massive, but this is the first non-subordinate who can make him feel this way.

Dongfang Mo couldn't understand why this was the case, so he simply didn't think about it, but radiated his ability and observed her condition through the faint sound that Yi Cheng made when he built his skills. In fact, Dongfang Mo's observation is much more convenient than looking directly with his eyes, not only is there no limitation of viewing angle, but even many small details that will be ignored by the naked eye are now presented in a very clear picture in his mind.

After observing Yi Cheng for a while, Dongfang Mo was even more surprised in his heart, because when Yi Cheng was building this skill, it was not at all like he was trying it for the first time, as if he knew this skill very well, every step was almost perfect, and every detail was completed very well. If it weren't for the fact that she still looked at the analytic formula in the book from time to time, Dongfang Mo would really think that she had studied it for at least a few months before.

Time passed minute by minute, and the three hours agreed by Dongfang Mo were almost up, and there was another person in the middle who asked to use the move laboratory, so Dongfang Mo went out and took that person to another move laboratory, and then came back immediately. Compared to just experimenting with a relatively simple attack skill over there, Dongfang Mo was still more curious about what Yi Cheng could do.

"Three minutes to go." Dongfang Mo looked at the time, and then looked at the situation on Yi Cheng's side, as the inventor of this move, Dongfang Mo knew that Yi Cheng would soon be able to complete this move. But even if it can be completed immediately, it is estimated that it will not be completed within three minutes, and Dongfang Mo can't interrupt her, if she waits, she is afraid that this last point will make her fall into a bottleneck, and she won't be able to end it for a long time.

"If it really can't be done, then the others of Hyundai can go back......" Dongfang Mo made up his mind in his heart, looking at his timer, a little nervous in his heart. Yi Cheng had been building here for more than two days in a row, but fortunately, it was time in the Holy Grail Battlefield, otherwise her body would not be able to bear it. In fact, even in the Holy Grail Battlefield, she will enter a very tired state after completing this item! Speaking of which, Yi Cheng's construction speed is already very fast, that is, Dongfang Mo himself to build a move with a difficulty of more than nine that he has not been exposed to, it is estimated that it will take five or six days......

"Buzz!"

Just when Dongfang Mo had just come up with such a thought, a roar suddenly sounded, and then the air began to tremble, as if something dangerous had scared them.

"Oops!" Dongfang Mo immediately knew what was going on, but at this time, he could only use this trick to solve the problem!

"The vocal range is fully expanded, the 'change' word formula is increased, and the subtle sound is eroded!"
