The Ground Wall is a purely defensive spell, and although it is not comprehensive, its range of defense is still very wide. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 The info wall technique can cover a radius of about 300 meters, and the smaller the range, the stronger the defense.

Once the Ground Wall is constructed, it is indeed a huge enhancement for the current Ark, and Ark can officially become a Level 2 caster with this spell.

Spellcasters from level zero to level 3 basically do not have much of a bottleneck, as long as the resources are sufficient, or spend a little more time, they can eventually become a third-order spellcaster.

However, reaching the third order is a real bottleneck, once it can't be broken, it will always be just a third-order spellcaster, and it will never be able to go further, which is the real reason why Ark wants to come to the four planes to find a way to break the limit.

Of course, Ark hasn't encountered a bottleneck yet, he just wants to become a second-level spellcaster first and have more life-saving ability.

Now that his mental power was sufficient, Ark didn't hesitate anymore, and he began to formally build a spell model for the Earth Wall Technique in the laboratory. However, as the best of the second-level spells, the Earth Wall Technique is one of the top spells, and its model is naturally very complex.

Ark felt very difficult just by looking at it, but he didn't give up, originally from the first level to the second level or even to the third level, the spells he came into contact with were more complex than the other, but his understanding of spells was gradually deepening, and he believed that the spell model of the Earth Wall Technique was still difficult for Ark.

As the days passed, it took Ark a full three days to memorize the spell model of the Earth Wall Technique, and then he began to try to simulate it with mental power. In the face of such a complex spell model, it is necessary to have sufficient mental power to be able to do it in one step, which is the real reason why Yak must wait for his mental power to reach 7 before he is willing to build a second-level spell.

Complex spell models require a lot of mental power, and the spell model of the Earth Wall Technique that Ark is currently simulating is a representative, it is so complex that it takes a lot of time just to write it down, let alone simulate it slowly, and once the simulation goes wrong, it will have to be restarted.

Therefore, Ark is careful in every step, but fortunately, Ark has plenty of time, and he can simulate it slowly, even if it is three, five, or ten days.

With enough time, it became much easier for Ark to simulate the spell model of the Earth Wall Technique, and he stayed in the laboratory, using his mental power to simulate the spell model of the Earth Wall Technique. Despite its complexity, with the support of a huge amount of mental power, the progress of Ark's simulated spell model is progressing steadily.

10 percent, 20 percent, 30 percent......

The Earth Wall Spell model that Ark was simulating was being simulated by Ark little by little, and it had reached more than ninety percent in three days, and nothing went wrong.

Now, it's only a little bit of success.

Suddenly, Yak was shaken, especially as he felt a large amount of earthy yellow elements frantically surging into his body, and he knew the result.

Succeeded, the simulated earth wall spell model was finally successful, and now that the model has been successfully simulated, then now Ark is experiencing the elemental entry into the body, which is the least difficult level for Ark.

As a large number of elements entered his body, Yak experienced another elemental ingress, and although he had already experienced many elemental ingresses, each time he had a different feeling.

Originally, Ark was a first-level spellcaster who could live for two hundred to three hundred years, but now, with a large number of elements entering the body, this is a second-level top spell, so Ark's vitality has increased rapidly.

According to the general lifespan of a second-level caster, a second-level caster can live between three hundred and four hundred years. It's an unimaginable lifespan, and it's just a second-level spellcaster.

It is no wonder that rumors circulate among ordinary people that the caster has mastered the secret of immortality, in fact, the caster has indeed mastered the secret of immortality, and his lifespan is more than ten times that of ordinary people, which is quite a long life.

Of course, no one can live forever, even those great beings who have surpassed the ninth order cannot live forever, they just live for a very long time.

Ark is still a long way from that realm, he is very excited now, he has worked hard for so long, and finally became a second-level spellcaster, and he is only thirty-five years old now, not yet thirty-six, this is a fairly young mage even among first-level spellcasters.

What's more, the current Ark is already a second-level spellcaster, if this is in Gray Winter City, it can only be done by those mages with huge power as their backing, and ordinary spellcaster families can't just cultivate such a young second-level mage.

Ark could clearly feel that there was now a new spell model in his mind, which was the spell model of the Earth Wall Technique, however, the current Earth Wall Technique could not be released, it was slowly accumulating mana, and under normal circumstances, it would take at least a month to accumulate the mana to release a spell.

However, Ark also brought some potions or potion materials from Gray Winterfell to shorten the time of mana accumulation, and he can shorten the time of mana accumulation. In this situation, if you can release the spell earlier, you can also have more strength to save your life.

Ark had just built the Earth Wall spell, but he wasn't satisfied, he was going to try to build the Storm Wings, and it would be too complete if he could build a second level 2 spell.

Unfortunately, Ark only tried it and gave up, because he felt that it was very difficult, and his mental power was completely insufficient, and he estimated that he would have to wait until his mental power reached 8 before he could build the Storm Wings spell.

Although he couldn't construct the Storm Wings spell, Ark wasn't too disappointed, and simply concentrated on using potions in the laboratory to shorten the time it takes to accumulate mana.

......

Ark doesn't care about the world in the laboratory, and accumulates mana with peace of mind, but the situation in the outside world has changed drastically. The Yagao Empire has been completely destroyed, although there are still some resistance forces left, but they can't become any climate, the overall situation has been decided, and the Nile mage has also returned to the Yagao Empire, preparing to launch an attack on the Fengqi Empire and the Caiyun Empire, completely annihilating these two empires, and eliminating all resistance forces in the four planes.

Although the caster's momentum is like a rainbow, there are also unsatisfactory places, such as the golden silk sword god that the Nile mage has been chasing and killing, and he doesn't know where to hide, and there is no trace of him, and even the Nile mage has no way to pursue and kill anymore.

This Golden Silk Sword God has always been a hidden threat, but the Nile mage didn't care too much, as long as the caster completely controlled the Quartet Plane, it was not easy to find the Golden Silk Sword God?

Therefore, now the caster side has gathered a large army, ready to move towards the Wind Rising Empire and the Colorful Cloud Empire. (To be continued.) )
