The reason why he was in such a hurry to buy a spirit rune and come back to study it, Lu Yun had his own ideas. The effect of the spirit rune on the surface is only similar to that of a grenade, but the actual working principle is very different.

The grenade relies on gunpowder combustion to instantly produce a huge amount of gas and then explode the skin, causing a huge impact and fragment damage.

But the Flame Burst is different.

It has no outer skin, so the power generated by the explosion should be roughly stimulated by the array above.

According to Lu Yun's thoughts, in addition to the runes on energy storage and explosion, this spirit rune also needs the blessing of at least several other formations.

Lu Yun first stood on the second floor of his laboratory.

"Heavenly Dao Laboratory, first reinforce this room of mine."

Lu Yun first instructed the laboratory to reinforce the room.

After all, if you want to do research, or study the flame bursting charm, you can't do it if the house is not strong.

Wouldn't it be fun if it blew up?

"The room is reinforced."

It is worthy of the Heavenly Dao Laboratory, this kind of thing is really a matter of one sentence.

Awesome!

Lu Yun began to touch his chin and think.

"First of all, no matter what it is, if you want to understand its principle, the first step is to use it yourself." Lu Yun took out a flame burst charm, and then summoned an experimental dummy in the room.

If you want to copy the Flame Burst Talisman, the first step is to know how powerful it is......

Lu Yun stretched out his index finger and middle finger, picked up a flame burst talisman, and then concentrated the spiritual power to his two fingers according to the spiritual power running route of the prop attack method, and then quickly gathered the spiritual power on the spiritual rune.

Suddenly, Lu Yun felt that his divine sense seemed to be connected to the spirit rune in his hand, and the spirit rune was simply like an extension of his body, and not only that, the surface of the spirit rune was also wrapped in a layer of spiritual energy in an instant, and the originally soft paper became like a piece of steel!

Lu Yun's eyes were fixed on the dummy five meters away.

"Go!"

Lu Yun let out a low shout, and then waved his hand fiercely!

Immediately, I saw that the flame burst out like a cannonball, hitting the dummy straight on.

"Boom ——!!!"

A violent explosion sounded, and the dummy was blown to pieces by this flame detonation charm, and the entire explosion range was about three meters in diameter!

"This power can be ahh Lu Yun's eyes widened: "A kilogram of TNT explosion can produce 4.2 million joules of energy, according to the calculation of 1 joule = 0.102 kilograms·meter, the energy released by one kilogram of TNT can move a one-kilogram object 420 kilometers, or a 100-kilogram object 4.2 kilometers." The power of this flame burst charm is roughly estimated to be ten grams of TNT! ”

The power of ten grams of TNT, don't look at this unit is not big, but the power is definitely not low!

It's no wonder that Izuku Lingzi said that this thing is invincible within the refining of qi, if this is really blown up, it is indeed enough to blow people up!

Now that the power is no problem, then the next thing Lu Yun has to do is to analyze the content of this flame bursting talisman.

Lu Yun sat at the table and picked up the paper and pen-

"Flame Burst Power: Approximately equal to ten grams of TNT explosion power."

"The effect of the above array diagram is known (guess version)-"

"Explosive Rune: The source of the explosive power of the Flame Burst Talisman."

"Energy Storage Array: Energy Storage."

"Psychic Connection: How a Fluffy Paper Can Hit a Target Depends on This."

"Material Reinforcement Array: Paper will be disturbed by wind resistance during flight in the air, and this Material Reinforcement Array is mainly to solve this problem."

"Function Trigger Array: By inputting spiritual power, all Array Diagrams can take effect."

"Structural Stability Array: All functions can be stacked stably."

Looking at these functions recorded on the paper, Lu Yun took a deep breath.

Whether the spirit rune can be copied, and whether the array diagram contained in it can be used for oneself is very crucial.

If there is no accident in the future, when the fifteen days are over, King Kong will definitely challenge himself.

Facing this kind of tank-like opponent, Lu Yun was very sure that unless he could arm himself to the teeth, defeat would be a matter of ironclad.

Although he is not interested in fighting and killing, he still wants face.

As soon as I entered the first inner disciple village, I was overturned, what do the chickens think? What do ducks think? What do geese think?

How will you mix in the cultivation realm in the future?

"Then we started analyzing." Lu Yun took a deep breath, and then began to prepare for the analysis of the spirit rune array diagram.

The first is the source material.

Lu Yun took out the rune paper he had bought before, and then arranged for the Heavenly Dao Laboratory to start copying all the patterns of the spirit rune on the rune paper.

He first copied the outermost rune on top of the spirit rune.

According to Lu Yun's thoughts, this thing should be the rune that the spirit rune will explode.

Soon, this rune appeared on the rune paper, and Lu Yun first protected himself - he directly got a set of protective clothing to put on, and it was a metal kind for bomb disposal.

After all, the power of this thing is basically equivalent to that of a grenade, and the explosive power of 10 grams of TNT should not be underestimated.

Lu Yun asked the laboratory to extend an aura pipe, and then aimed at the experimental rune paper that had been made.

Spiritual power is charged.

Suddenly, Lu Yun saw that the rune paper began to shake violently, and about five seconds later, with a "bang", a huge fireball appeared, and the fireball was about a meter in diameter, thanks to Lu Yun's carefulness.

Otherwise, he might have been disfigured just by this moment......

"Damn, is it so fierce?" Lu Yun is still scared in his heart now: "Thanks to my full consideration, otherwise the calf will be finished!" Isn't my handsome face gone! ”

A cold sweat that!

But anyway, this explosive rune Lu Yun has figured it out, and this thing will be recorded first, and it may be used somewhere in the future.

Lu Yun called out to the Heavenly Dao Laboratory: "Laboratory, you have records of runes and formations, right?" ”

Tiandao Laboratory: "It's all there." This experiment is designed to allow the host to research various functional artifacts as quickly as possible, so this kind of miscellaneous work can be automatically solved for the host. ”

Lu Yun gave a thumbs up: "Awesome!" ”

Lu Yun was particularly satisfied with this function of the Tiandao Laboratory.

Do you see a scientist who does an experiment without a deputy?

Why?

Isn't it because the deputy can solve a lot of time-wasting chores?

If you need to do everything yourself, then you don't have to think about it, you can exhaust people to death, and you can't do a few experiments.

Just this explosive rune, if Lu Yun drew it bit by bit, there would not be a day or even a day or two that he couldn't draw it, and this was just a drawing.

What if the drawing is not standard and has no effect?

Right?

But with this Tiandao Laboratory, it's different, just copy and paste, perfect!
