After killing so many twisted souls, Gavin gained more than fifteen thousand soul energy. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

This is an unprecedented harvest and means that he can learn a lot of spells.

To learn spells through soul infusion, 1 Tier 2 spell requires around 100-300 points of soul energy, and a Tier 3 spell requires three times as much soul energy, about 300-1000 points.

As for Tier 4 spells, each spell requires more than a thousand soul energy points.

Learning spells is a gradual process, and many high-level spells have pre-set basic spell requirements.

For example, the core part of the spell model of the third-order spell "Lianzhu Fireball" is very similar to the second-order spell "Fireball". The core part of the spell model of the "Fireball Technique" is very similar to the Tier 1 spell "Inferior Flame Orb".

If the knowledge of "Inferior Flame Ball" is equivalent to elementary school mathematics, then "Fireball Technique" is equivalent to junior high school mathematics, and "Lianzhu Fireball" is equivalent to high school mathematics.

Although this analogy is not accurate, because the relevant knowledge of "Lianzhu Fireball" is much more advanced than the three-year high school mathematics course, and the amount of memory is much larger.

That's what it means.

You can't learn high school math without learning elementary math, and Gavin can't directly learn Tier 4 or even Legendary level spells without a relevant magical foundation, although the soul energy he has accumulated now is enough to learn a less powerful legendary spell.

"Advanced Invisibility, Advanced Mage Armor, Dragon's Breath Imitation, Stone Skin, Biological Positioning, Transfiguration, ......"

Gavin had too many spells to learn.

A senior mage often knows a dozen or even dozens of spells. The more spells learned, the stronger and more resilient the mage becomes.

Fifteen thousand soul energy seems like a lot, but in fact, you can't even learn a second-order spell, and you can't learn half of it.

Soul energy is limited, and Gavin can't use it all to learn Tier 2 spells.

Among them, he chose more than a dozen second-order spells, which consumed more than two thousand soul energy.

These spells are not chosen randomly, they are some of the most commonly used and popular spells by mages, and some spells are also precursors to certain Tier 3 spells. Only by learning them can Gavin learn the corresponding high-level spells.

Subsequently, Gavin browsed through the list of Tier 3 spells and finally selected a few Tier 3 spells.

For example, "Dragon Breath" is a spell that many high-level mages will choose to learn, because the effect is really good, and it is one of the strongest range spells in the 3rd order spell.

And the "Monster Immobilization", which is a cut above the second-order spell "Human Immobilization", is its advanced spell, which can immobilize all living creatures, and does not have to be limited to humanoids.

There is also the "Deflection Force Field Enchantment", which is the defensive spell cast by the Ooze Master, which is an advanced version of the "High Mage Armor" with stronger defensive capabilities.

Gavin didn't learn Tier 4 spells.

Because it was an archmage-level spell, it involved a much more advanced knowledge of magic. Gavin's understanding of magic is not enough, and his accumulated magical knowledge is not rich enough, and he is not qualified to learn any of the 4th order spells.

He had spent a total of more than seven thousand soul energy points, and there were about eight thousand points left.

Can't spend all of it on learning spells, Gavin plans to use some of his soul energy in exchange for high-level alchemy knowledge, because he really likes alchemy.

Also leave a portion of your soul energy for backup in case you need it.

With all of that done, Gavin turned his attention back to the underground mud world.

There must be some secret hidden here, otherwise it would not have been possible to create such a strange world.

This is already an underground world hundreds of meters below the Death Swamp, and there is a huge amount of mud and turbid water above, but it is blocked by a special energy and mage barrier, and no matter how strong the water pressure is, it cannot break through the natural defenses here.

And the air here is fresh, and there seems to be some special way of flowing and exchanging breaths, but Gavin just can't find where and how it circulates from, and he doesn't even have a clue.

Gavin speculated that unlocking the secrets of this place would require legendary mage-level expertise and months or even years of painstaking research. At least the ooze master shouldn't have unlocked the secrets here.

"It's time to go." Gavin shook his head slightly.

Morgana is still in the Swamp of Death.

Although Morgana is very strong, Gavin still has a little worry and worry in his heart.

Then, just as he was about to leave, he suddenly stopped, and at the same time activated the "Advanced Invisibility Technique" solidified on the elven cloak, and disappeared.

The next moment, there were ripples in the space, and three figures appeared in front of Gavin.

Gavin's eyes shrunk.

Because of these three figures, one of them is the Fire Master!

He's back!

How dare he come back? He can't be a match for a master of ooze and a legendary ooze monster!

Could it be because he found two helpers?

Or is it because he already knows that the legendary ooze monster was killed by the fire dragon Amy?

Gavin turned his gaze to the other two.

The first thing he saw was a shield defender who was three meters tall.

Shield Defender!

A shield guard with a fiery red glow all over his body, the appearance was no different from that of an ordinary shield guard, but Gavin sensed energy fluctuations far more powerful than himself from its body—arcane energy fluctuations and fire elemental energy fluctuations.

This means that the shield guardian in front of him has an energy level of at least the archmage level.

The fiery red body was made of some kind of metal, and this metal Gavin happened to recognize:

It's fire gold!

The value of fire gold is several times higher than that of Burning Iron and Mithril, and the manufacturing cost of such a shield guard, even if you don't count the alchemy laboratory or golem factory required for manufacturing, not counting the materials required for enchantment and the price of spell casting, only counting the material cost, I'm afraid it will exceed 100,000 gold coins.

This is a shield defender worth at least 200,000 gold coins, which is much more expensive than many legendary pieces of equipment, such as the legendary Tier 1 longsword "Killing Sword" of the Barov family's Sword Master.

So there is no doubt that this is a Legendary-level shield defender.

Not to mention that compared to ordinary shield defenders, even compared to the Iron Golem with a challenge level of 13, it is much stronger!

Creating such a shield protector is much more difficult than cultivating an archmage with a title like the Fire Master.

This shield defender alone is probably enough to defeat and kill the legendary ooze monster.

Fire gold is the symbol of the magic acropolis "City of Fire". Morgana once said that only the "Lord of Flames" knew how to synthesize fire gold.

It is impossible for the Flame Master to have such a shield defender, and even in the huge "Flame City", there are only two or three people who have the ability to possess it......

If you consider the rumored relationship between the master of the fire and the teacher, then the origin of this shield guardian is about to come out.

This is the shield protector of His Excellency the Lord of Flames!

This means that the Lord of Flames has really set his sights on here! And for himself, it is impossible to avoid the gaze of such a legendary mage, right?

Gavin was shocked and speculated, but both the Flame Master and the Shield Guardian stood behind.

Standing in front was a female mage who seemed to be in her thirties.
