After the Battle of the Greenforest Tribe (Goblin Tribe).

The Goblin High Priest and fifth-level spellcaster 'Karadan' became the third dragon vein dependents under Udi's command, and the strongest family member who came later.

In that battle, if it weren't for Udi's last appearance and a swift assault to end the battle, the goblin side would have won in the end, and the kobold side led by Shiki would have ended with the defeat.

Now, the defeated Green Forest tribe, led by the High Priest Caladan, has migrated their tribe to the Black Blood Valley.

According to statistics, in the Battle of the Green Forest, sixty-one kobold warriors of the Black Blood Tribe were killed, and one hundred and forty-two Goblin warriors of the Green Forest Tribe were killed.

In fact, both sides have suffered heavy losses.

After all, the young and middle-aged kobolds of the black blood tribe were less than two hundred, and they lost nearly one-third of their soldiers in one battle.

On the other hand, the total population of the Green Forest tribe has reached more than 750, but half of them are female goblins and juvenile goblins, and adult goblin warriors are only about 300.

It can be said that in this battle, the Green Forest tribe killed nearly half of the young and strong combat strength at one time.

However, the only consolation for the two tribes is that the true core combat power of the tribe has been retained in the end.

The core combat power of the black blood tribe, the leader Shiji and the three forest trolls of Mondo, Zaku, and Zameng, a total of four, and Mondo, who was the most seriously injured, was finally pulled back on the death line.

The core combat power of the Green Forest Tribe, the High Priest Caladan and the Seven Great Bryn Warriors. The creature level of the seven Big Blin warriors has reached the second level, coupled with the strong physical fitness of being monsters, although several of them have been hammered badly, they can regain their combat effectiveness after recuperating for more than ten days.

To sum up, the battle seems to have suffered heavy losses, but in fact it is harmless.

After all, whether it is a kobold or a goblin, although there are not many advantages, they are very specialized in breeding.

Among them, kobolds have a slightly worse ability to reproduce, but they can usually give birth to a litter a month.

And the goblins, which are almost full of reproductive ability, can give birth to a litter in half a month.

However, the above reproduction speed must meet enough food as the first premise, without enough food, the speed of reproduction is inevitable.

Time passes slowly.

In the blink of an eye, more than half a month has passed.

Under the waterhole and waterfall, in the humble dragon's nest.

Udi opened his eyes.

Silently chanting a magic spell in his mouth, three seconds later, a black light shot out from Udillon's fingertips and struck the piranhas wandering in the pool of the dragon's lair.

The piranha, which was still full of vitality and swimming, stopped moving for a moment after being hit by the black light, turned its belly over, and slowly surfaced.

He's dead.

Although the effect of the weakness technique is to drain energy, and the body of the person in the mission falls into a state of weakness, there is also a premise here.

That is, the creatures that are affected by the effects of the Weakness Spell, and the vitality should not be too weak.

If it is too weak, the energy will be directly drained, and the energy will be zero, which will naturally be death.

The piranha looks ferocious, but it doesn't even have a level in terms of creature level, and it is an inaccessible creature.

The Weakness Technique is a one-ring spell, and hitting zero-level creatures such as kobolds and goblins can be said to be dead. Even if it hits a second-level creature like Goblin, it will also make the opponent weak, and his strength will be reduced to freezing.

"In twenty days, the First Ring Weakness Technique has finally been constructed." Udi slowly lowered the dragon finger aimed at the pool, and his expression was silent.

Spells, indeed, are hard to learn.

The caster profession also really requires a lot of energy.

As a black dragon, Udi is still the kind that is open, with a huge storage of mana that ordinary creatures do not have, and this innate superior condition makes it a great help for Udi to choose to embark on the spellcaster profession.

If the mana store of a first-level spellcaster in the human race is assumed to be 100 points, then Udi may have 10,000 points.

The human spellcaster needs to save a little bit of mana in the middle of the battle, so that he can cast one more spell, while Udi only needs to think about which spell is more effective and powerful.

But in addition to the strong advantage of the innate race in terms of magic, the dragon really doesn't have that much advantage in terms of the talent of learning spell speed and comprehending the truth of spells.

Taking the black dragon as an example, as a true dragon of the water system, if you learn water attribute spells, it will indeed have certain bonuses, such as learning faster, such as water spells will be used stronger than other spellcasters.

But only in the water system.

The other dragons, the red, the blue, and the green, were the same. Learning spells that fit your own attributes will get twice the result with half the effort, and learning spells that don't match your own attributes will not be much stronger than ordinary human spellcasters, and there will be no bonus to the power of the spell casting effect.

"It's a pity that none of the four spells of the Calladan Society are water-based, but the most powerful spell is still fire-based." Udi shook her head and closed her eyes.

He refocused his attention on his spiritual world.

A gray transparent rune was suspended above the vast spiritual ocean, emitting a faint glimmer, and under the light of the rune shimmer, the surrounding spiritual power seemed to be more active.

This gray transparent rune is none other than the [One Ring: Weakness Technique].

In addition to the cultivation of spellcasters that require years of refining external elements to control more magical power, the core of the caster's cultivation is the cultivation of spiritual power.

The increase of mental power is one of the necessary prerequisites for the caster's class level to increase.

Although there are many ways to cultivate spiritual power, the mainstream one is still cultivated by obtaining spell runes.

Each time a spell rune is condensed into one's own spiritual world, it can continuously hone the caster's spiritual power. The more spell runes you condense, the higher the level, and the faster you will hone and improve your mental power.

In addition, there is a difference between spell runes of the same level.

Like the weakness spell rune that Udi had just mastered, it was still transparent, indicating that he was only at the level of the beginner of this spell.

When the rune changes from transparent to substantial, then it is proficient in this spell, and the sharpening of mental power by the mastery-level weakness rune is several times the effect of the entry-level weakness rune.

And if the materialized rune can sink into the spiritual sea, then it means that the caster's mastery of this spell has reached the highest realm of returning to the basics.

True-level spell casts usually have the characteristic that they can be instantaneous.

In addition to the instantaneous spell, the effect of honing mental power will be increased again, and the power of this spell will also be greatly enhanced, and the mana cost of casting this spell will also be greatly reduced.
