Chapter 3749: Surprise

Lu Shan really doesn't understand...This wind thunder technique is no different from the previous ones. The air he compresses will not be more than before, and the degree of compression of the air is also the same as the previous few times. It is not specifically compressed to be smaller.

But this time, the explosive power of the wind and thunder technique was obviously more than twice that of the previous ones!

At this point, when he saw with his own eyes that the place where the small transparent ball was placed just now, a large pit with a radius of nearly five meters and a depth of at least three meters... can be seen!

This power is more than ten times more powerful than a real grenade, and even ordinary shells are not as powerful as this.

If just replaced by some ordinary people standing within 30 meters of the explosion point, I am afraid... there are really few who can survive! This doesn't... even that circle of smaller trees was knocked down by the aftermath of the explosion.

Obviously the same spells are used, and the same true essence is obviously consumed, but...why is the power of the wind and thunder technique so amazing after the explosion?

Could it be...because of the superposition of the sealing character technique?

Lu Shan frowned and pondered for a while, probably had some guesses...

That's the principle of sealing!

It's like if the gunpowder is placed in an open place and ignited, what will be released is a big flower, and it will not cause much destructive power.

But... if the same amount of gunpowder is placed in a relatively closed wooden barrel and then ignited, then... the explosive force caused by the ignition of the gunpowder is quite amazing.

If...put the same amount of gunpowder in a better airtight shell, and then detonate it with a firing pin... then what will be launched will be an amazingly powerful cannonball.

For the same reason, the previous wind and thunder technique used true essence to wrap the air and compress it to a limit.

Then... the true essence wrapped outside is equivalent to creating a closed space for the air inside.

This kind of enclosed space should be extremely tight. Otherwise, if there is a leak, it will not be possible to compress the air inside... But the problem is that there is often no real absolute closure in this world, as As the old saying goes, "There is no impermeable wall in the world."

A newly built wall should be rigorous in every way, and there can be no air leakage, but... if it is strictly checked, no matter how well built, it will inevitably be breathable.

For the same reason, he wrapped the air in his true essence, which seemed tight and seamless, but in fact... no matter how tightly it was, it was only relative.

But... with the addition of a layer of sealing character technique, this kind of sealing effect may have reached an absolute degree of rigor in theory.

In this way, when the compressed air loses its temporary stability and suddenly explodes, the power displayed may suddenly increase several times.

He originally wanted to see if he could keep the air ball formed by the wind thunder technique for longer after adding this layer of engraving text.

As a result... the retention time didn't increase much, but it increased the power of this spell a lot! This... can be regarded as the East is not bright and the West is bright!

It's just that the power of this magic technique is already not small. Now although the power has increased several times, but... the fundamental problem has not been solved, and the preparation time for this magic technique is still too long! Moreover, after the spell was completed, the time that could be stayed did not last a few more seconds. In this case... this spell is still too tasteless, and there are too few opportunities to be suitable for use.

This idea is good, but if it is not practical, it is also in vain, so... do you want to give up?

Lu Shan hesitated for a moment, and suddenly felt like he could reduce the amount of air he grabbed. In this way, the total amount of compressed air is reduced, but the true essence used to restrain the air is not due to this. Decrease, then...or the stability of the final compressed air ball can be increased.

Thinking of this, Lu Shan refreshed his spirit and experimented again...

The air mass he grabbed this time was about one-third less than before...that is, he grabbed a mass of air of about two cubic meters, wrapped it in true yuan, and quickly began to compress it.

Not to mention...Because the air captured is much less, the compression process actually saves a lot of time. Before he had to compress a mass of air to the limit, it took at least one minute, but now...it only took 35 seconds to compress this mass of air almost to the limit!

"seal--"

At the same time, Lu Shan's other hand had already pinched the tactics quickly, using his true essence to outline a rune with the word "Feng" in the air.

Then he stretched out his hand and pointed out that the talisman culture made a big net, shrouded in a small air crystal ball that had shrunk to the size of an egg yolk, and then the rune shrank quickly and clung to the small ball tightly. , Turned into some seemingly complicated and mysterious patterns.

It was another success, but Lu Shan wasn't sure how long the Fenglei Ball could stabilize this time, so he hurriedly put it gently on a clearing, and then drew away again.

Moreover, this time he took the lesson. Although he felt that the air mass he grabbed this time was much smaller, even if the same explosion power would exceed the normal state, it should not be too strong, but he still avoided more than 30 meters away. Just stopped.

Huh...Ten seconds have passed, and it hasn't exploded yet. This time...should it succeed?

Lu Shan was full of expectations. He was very interested in this combination of spells. He felt that if some results were obtained from the research this time, he might as well learn more messy spells later. Maybe he could use different spells. Put them together, and then what magical change happened!

But at this moment, I suddenly heard a piercing sound from the air, and then a cold voice screamed: "What happened here?"

Lu Shan looked up in amazement, and suddenly saw a figure flying down from the direction of the top of the peak with a flying sword, flying down towards him.

Because it was night and there were no lights around here, Lu Shan couldn't see what the person on the flying sword looked like, but... from the cold voice, he probably heard... this person seems to be Outer Door Three. Elder Qiu among the elders.

Lu Shan guessed that he was experimenting with combinatorial spells just now. The explosion came too loudly. It was in the night, and the sound spread far away, so it alarmed the elders at the outer door!

He was also helpless about this...As a person from a modern society, he naturally knew that it was in the middle of the night, and it would be very disturbing to make such a noise suddenly!

But what can he do? Sect Master Xia gave him two days to practice the spells, so he can only get up early and greedy the dark. Even if something disturbs the people, he can only be sorry!
