The Eternal Martial Emperor
86

The old man had to be white-haired, wood-thin, with his extraordinary style, and the image of an earthly leader.

And his breath was as strong as the sea, enough to shock everyone on the scene, including that supervising deacon.

There was no doubt that he was a third level martial artist!

When he saw the old man, Liu Long immediately showed his respect: "Master, what are you doing here?"

When they heard Liu Long's words, everyone widened their eyes in shock.

It turned out that the old man with white hair was Liu Long's master, Lu Yi.

“Older, are you here?” Seeing Lu Yi, even the dean of the proctor greeted him respectfully.

However, Lu Yi turned a deaf ear to their greetings. He grabbed the detonator in the deacon's hand, and then his face was full of shock.

“How about an old man, am I right?” Lin Yun asked Lu Yi lightly, and a vague tone and expression seemed to have expected this scene.

Actually, Lin Yun had discovered that Lu Yi was living nearby. It was for this reason that Lin Yun deliberately stated these two Fuyu questions to encourage Lu Yi to appear.

Everyone was completely shocked when they heard Lin Yun's title to Lu Yi.

Lu Yi was the elder of Yuzhou Wufu!

Lin Yun called him "the old man". Is he impatient?

For a time, everyone looked at Lin Yun with theater eyes, seemingly looking forward to how Lu Yi would punish Lin Yun.

However, what everyone did not expect was that Lu Yi did not mind Lin Yun's disrespect for him and did not even have the slightest anger on his face, either, just stared at Fuyu in his hands and spoke to himself.

"I didn't expect it, I really didn't expect that this talisman also showed a deviation of a thousandth of a millimeter, and the old man didn't find it, the old man was being too careless!"

When speaking, Lu Yi looked at Lin Yun, his eyes full of admiration: "You can find a deviation of one thousandth of a millimeter in an instant. How's this happening?"

Words came out, the spectators were shocked!

Everyone, including the deacon, was startled by the thunder and looked at Lin Yun with a petrified expression.

The entire scene became silent at this moment, as if time was frozen.

They originally thought that Lin Yun said that there was a deviation between the two Fuyus, but they were just making it up. However, he never expected that he was actually affected by it.

It was incredible that a young man who did not know where to find the subtle deviation that even a master like Lu Yi had missed in an instant!

"How do you do it? Is this hard?" Said Lin Yun faintly, as if he was talking about a trivial thing that could be easily done.

Lu Yi barely vomited any old blood.

Deviations on the micro scale, even his parents who have studied Fuyu for years, are hard to find, and often fail.

In Lin Yun mouth, it was said to be as easy as eating.

The crowd was also choked by Lin Yun's words, and for a long time they couldn't speak.

After half a ring, I saw Lu Yi take a deep breath and asked Lin Yun excitedly: "Sister, sister, You just said that the drawing material should not be made of explosive animal skin. What type of skin should be used?"

In fact, as Lin Yun said, all the explosive symbols on the market would explode on their own.

The number of accidents caused by this has been many, causing many casualties.

Although spontaneous outbursts are common, one can never find the true cause, and can only think of them as uncontrollable natural phenomena.

Until passing by here today, Lu Yi accidentally heard Lin Yun's words, and then changed his perspective to reflect on the matter.

Lin Yunmian said expressionlessly: "In the material of the third level drawing, only the skin of the split-toothed beast is suitable for the blasting symbol."

"If you want to talk about the charm power of blasting, even though the skin of a split-skinned animal is not as good as the skin of a crushed animal. However, split-skin animal skin is very stable and will not explode due to external factors.

"Is this cracked tooth? I've tried this before. But the power was too small and the cost was too high, so I gave up and some people in the market used it." Lu Yi recalled.

Lin Yun looked at Lu Yi cynically, as if looking at a less talented apprentice: "I told you before, that's why you were born."

"Your drawing technique is not mature enough, and drawing tools are useless. That is why the power of the finished product is not enough. You can only rely on unstable materials like explosive beast skins to increase your strength."

Everyone cannot hold their breath.

When Lu Yi was not on the scene before, Lin Yun pointed out that Lu Yi's flaws were enough to let everyone quietly whisper in his heart.

At this moment, Lin Yun actually landed on Yi's face, and said without worrying that Lu Yi's drawing technique was not mature enough, which blinded everyone's eyes!

Wasn't this kid really afraid to bother this master?

"Son, you have repeatedly underestimated my Master! I'll teach you for him!" Liu Long finally could not bear it, threatening to teach Lin Yun.

And yet.

He had a chance in the future and was captivated by Lu Yi.

"Go away, don't be a teacher!"

After Lu Yi flew Liu Long with a slap, he turned around casually and asked Lin Yun: "Male sister, since you said that drawing tools should not use black gold pens, you know that you should not use black gold pens, what should I use?"

"Just use an ordinary volcano pen," said Lin Yun lightly.

Lu Yi frowned slightly and asked puzzledly, "A volcano pen? Isn't this a lower level drawing tool than a black gold pen?"

In most people's minds, the higher the level of the drawing tool, the better the effect the runes were drawn.

Therefore, no matter what kind of talisman they drew, they usually used a black gold pen, but they never considered whether it was a match or not.

After thinking about it, Lu Yi said to Lin Yun again: "And the structure of the volcanic pen is more unstable than the black gold pen. It should be easier to leave material residue, right?"

Lin Yun still explained expressionlessly: "Either the black pen or the volcanic pen. No matter what the pen is, there will be traces of residue in the drawing process."

"It is true, as you say, that volcanic pens are more likely to leave material residue than black gold pens."

"But unlike the black gold pen, the residue of the material of the volcanic stone pen will not only reduce the power of the blasting symbol, but also play a certain advantage."

"This is because in a volcanic pen, there is a component called gunpowder, and it is this component that increases the strength of the blasting symbol."

After listening to Lin Yun's words, Lu Yi patted his head: "How have I never thought about this matter before? It's really alive!"

Lu Yi also knew that gunpowder was highly flammable and could explode in an enclosed space.

Volcanic pen contains high concentration gunpowder. This point has been ignored by him.

It was not until Lin Yun mentioned it at this moment that he suddenly realized that he was so stupid before!
