Looking back at crescent college, Lena was not idle while waiting for the second round of peas to mature.

At night, in Lena's room, he sits on a chair. On the table in front of him is a parchment recording a magic model.

This magic model is obviously more complicated than the standard one ring magic fireball. There are many more magic nodes and the tracks of magic flow. At first glance, it's complicated, and it's hard to distinguish between lines. If you let Claire see it, I'm afraid he will raise his hand and surrender within ten seconds.

But that's what Lena is aiming for tonight.

Standard two ring spell, explosive fire.

Unlike the improved third-order magic, Pluto's pyrotechnics, this basic pyrotechnics only needs the level of the second ring to master, but its destructive power is much higher than that of the fireball magic of the first ring. It is more suitable for the mages who choose defensive magic when inscribing the first ring.

There are several reasons why Lena chose this spell.

Originally, he wanted to learn a defense spell from Bao. But soon, Lena learned that the defense spell of the low level mage stage is basically a little stronger armor. As long as it can be upgraded to the medium level, a magic barrier that can be used at any time is enough to despise all the low level defense spells. Therefore, in the idea of saving, Lena decided to save money Don't waste precious space for inscriptions on low-level defensive spells that will be replaced in the future.

Similarly, the fourth-order phantom morph can move at a high speed in the designated area. As a kind of displacement spell, it has become the future choice of Lena. Therefore, the low-order similar spells will not be considered.

After these considerations, Lena was originally prepared to engrave some other attributes of magic, but he later decided to challenge another way under the guidance of President Dmitry.

That's override.

As we all know, mages rely on the corresponding level of magic to be engraved in the heart lake. Once engraved, it cannot be eliminated and replaced. This magic will stay in the heart lake forever. Mages can release it instantly without any preparation when using it.

But there are exceptions.

Just like the second ring spell, the explosive fire spell is actually an upgraded version of the first ring spell fireball. Its spell model is based on fireball, and the effect is very similar. Only the difference in power, such a spell can be overridden.

It's easy to understand that Lena upgraded his fireball skill in the heart lake to explosive fire skill. In this way, he won't lose the space to engrave the magic in the heart lake, and he can get a second ring magic skill, which can be regarded as a steady business.

Having said that, most of the mages will not take such a seemingly "advantageous" approach when they are advanced. The reason is that it is too difficult.

In addition to having a profound understanding of the two spells, rewriting also requires an extremely accurate grasp of the spell model, the control of magic, and the huge magic to maintain this fine process.

To put it simply, a mage who can achieve the required level of rewriting has already been advanced even by ordinary means. There's no need to bother so much to save space.

The number of spells that can be engraved on Xinhu varies from person to person, but the total number is between 20 and 50, which is enough to cope with most situations. Therefore, unless a mage is striving for perfection, there is no need to pursue rewriting.

But that's not a problem for Lena.

After receiving feedback from the world for several times, his disposable magic reserve has far exceeded that of ordinary mages of the same level. This can be seen from Reiner's fireball. Although he can achieve high combustion efficiency by using the Hydra element, Reiner's own magic reserve is also one of the reasons why this spell is so powerful in his hands.

In fact, although the spell model of explosive inflammation is complex, it is just a line on the plane, which can be easily mastered and improved.

Generally speaking, it will take at least a year for mages to adapt to their own changes and make magic penetrate and transform their bodies before they can continue to make breakthroughs. This is the most stable way.

But if we use the method of override to advance, then we can shorten the adaptation process to a few months. Coupled with the magic of hornheim gold cup transformation, Lena has met the requirement of promotion to the second ring, and immediately decided to try to break through.

If the experiment is successful, Lena is bound to go to Berger city again to visit the albioles. He is not sure whether his identity and the hornheim gold cup can frighten the albioles, so it is very urgent to improve himself in time.

Of course, as President Dmitry said, the world feedback Lena gets is gradually effective. With his growth, Lena will be a little assisted in his advancement. Without these feedback, even if Lena has enough magic and theoretical knowledge, it will be very difficult for him to quickly promote to the second ring.

Closing his eyes, Lena dived into the lake of his heart.

It's a peaceful, sunny and sparkling scene.Gently waving, the sun and the moon rotate, the sun immediately goes down, the bright moon rises, and at the same time, there are bright stars all over the sky.

When several stars light up, you can see that this is the magic node of fireball, which has been engraved in the heart lake.

Floating on the lake, Lena sank his heart and palms, and more stars flew out into the night.

These starlight trace brightly, and the already bright stars reflect each other. Soon, in the sky, the starlight is out, and only two nodes of the magic model are flashing.

As you can see, the trajectory of fireball is constantly extending, connecting the various stars. Gradually, the two magic models are integrated into one, shining in the Obsidian night.

Lena felt the two spells. He kept calculating in his brain and tried his best to upgrade fireball to explosive fire.

Hum -

in an instant, the flame bloomed from the stars and lit the whole sky in an instant along the dazzling magic track.

The deep and dark night, suddenly like the coming of day, is bright.

In the palm of Lena's hand, a faint blue flame ignited. The pure ice like blue quickly spread, and suddenly expanded from a fist sized fireball into a huge flame with a diameter of more than ten yards.

But soon, the expanding flame immediately contracted and turned into a ball of light the size of an egg in the palm of Lena's hand.

Understanding, Lena will throw it out, the ball of light flying at high speed, hit the front of the cliff.

First, a little light fell into the rock wall, and then countless lights burst from the contact point. At the next moment, the hot wind began to sweep across the rock wall. The bright light was like a flowing liquid, swaying in the huge impact force, and the explosion sound didn't break out until now.

Hum -

in Lena's field of vision, the towering rock wall turned into dust bit by bit, and then, at the same time of hearing the roar, the withering and decaying force completely destroyed the rock, filled with smoke, and the hoarse dry and hot air roared.

It's like being hit by a meteorite from outside the sky. The scorching wind is turbulent.

With a wave of his hand, a cool breeze blew away the smoke that blocked his sight. Then he saw the rock wall that had just been hit by the explosive technique.

To be exact, it's something that used to be a cliff.

The whole rock was sliced smooth and flat, just like a scoop of ice cream. No collapse or debris could be seen. Everything that was hit had vaporized into smoke. At the edge of the explosion, we could see that the brown soil had turned into shiny quartz, which was enough to see its high temperature.

"This is the explosive technique?"

Lena looked at his palm. The effect of this spell seems to be a little different from what he imagined?
