Du You was right, the additional ability of energy burning was indeed an essence skill.

Energy burning is not an active attack type, but a passive trigger. When an attack hits an enemy, it can ignite a part of the enemy's energy and perform a second kill from the inside out.

On the one hand, it can reduce some of the energy in the enemy's body, and on the other hand, it can also cause damage to the enemy, as well as great pain. This kind of damage from the inside out is not so easy to immune.

Unless its own energy is very high-level, or extremely condensed, or the energy type is special, there is no way to be immune to this move. This is especially useful against powerful and hard-to-kill enemies.

After this evolution was completed, Du You did not continue to go out to clean up the giants, but stayed in the territory. Because Du You found that his territory experience was already very close to the fifth order, but it was just a little short.

Director Wang is still in charge of the Central City, while Li Daxian has been setting off with the army and continues to put pressure on the giants.

After another day, Du You found that his experience was finally worth it. This still means that he is about to have a fifth-order territory, and this territory has also been promoted to the extreme in this world.

Whether to increase the level of the territory, the territory advancement requires 100,000 blue crystal coins.

Well, this really can't be done without the support of the academy, just 100,000 blue crystal coins is equivalent to 10 million citrine coins, and he can't even take out such a large amount of citrine coins, let alone the essentially different blue crystal coins.

Of course, for the sake of the academy's cultivation of students, this is very beneficial to the academy, otherwise the academy would not have come up with so many crystals and materials to help Du You tide over the difficulties.

Du You did not hesitate and immediately reported to Director Wang. Director Wang suddenly stood up from his chair and laughed loudly: "Okay, the two fifth-order territories, together our academy occupies an absolute advantage. Haha, the No. 2 territory over there of the Alliance Comprehensive Academy is still a third-order, and it can't reach the fourth-order. ”

It's no wonder that Director Wang is so happy, he really completely suppressed the opponent this time.

The crystals and materials that had been prepared for a long time were shipped over one after another, and the support of the academy was spared. 100,000 blue crystal coins were put into it, and soon the entire territory began to enter an advanced state.

Looking at the speed of this upgrade, it will also take more than a day. And Li Minglu, who had been prepared for a long time, had already begun to command the soldiers and civilians of the entire territory to start preparations, and began to expand and build as soon as the territory was upgraded.

Du You looked at the panel, some of the things provided by the academy during this time had also been digested. Not to mention the others, the new city wall drawings given to them by the academy solved a big problem.

Because the level of his own city wall was too low, the academy gave him a set of fourth-order city wall drawings.

Runic Walls (4th Order):

Steel and rock structure, engraved runes inside, carved outside, up to 100 meters, with gates and other outbuildings, including hollow secret passages, defense 40 + 40 magic resistance 40 + 40, with magic barrier, magic barrier no dead ends, defense doubled.

Coupled with the materials that the academy had mobilized for itself, the city walls in front of and around it had now completed the transformation of the fourth order. This kind of fourth-order level city wall, as long as the energy is enough, even a fifth-order giant will not want to break through for a while.

Besides, it's impossible for a fifth-order giant to come and look for trouble now. Because as the academy continues to oppress, the giants are gathering towards the clan of the flame giants, and there is no time to think about anything else.

Even if there are a few flame giants who don't act, that kind of giant will generally not come out easily, and it is even less likely to clash with them. Now the progress of my own academy is definitely the fastest.

A little more than a day later, the Territory Advancement was completed. Du You looked at the tall City Lord's Mansion, this City Lord's Mansion was the appearance of a giant city, a huge fortress fortress type, and the structure was very rough. Now this City Lord's Mansion itself is a huge fortress, but unfortunately, with the increase in level, the City Lord's Mansion has no other special power to increase.

No way, although the City Lord's Mansion is an important building, what really matters is the basic skills and other outbuildings.

"Well, it feels good to have a fifth-order territory. Director Wang walked over with a smile.

Du You nodded: "It's very good, but it's a pity that my current strength is not yet the fifth order, so it's a bit high-matched." Du You nodded without denial, and Director Wang laughed loudly.

"Hahahaha, that's true, you're much better than us. The person to whom this territory belongs is Li Daxian, and this is the first time he has a territory. You little one, you're much faster than we are. ”

Director Wang looked at Du You with deep meaning, as if to say I understand. Du You didn't say anything, just opened the panel and looked at the new attributes of his current territory.

Territory: Central City (5th Order, Giant World, Max Tier)

Lord: Du You/Deputy Lord: Li Minglu

Territory income: 4,000 Aquarite per day. Cost: 1200 Aqualite coins per day.

Population: 1,000,000

Strength: 2443

Alien population: 0

Attached World: None

Channel: None

The territory has undergone a huge change at this time, and the upper limit of population and strength has disappeared, which means that your own population can be created without restriction as long as you want, which is probably the most terrifying.

Of course, creating such a large number of people is actually not very useful, not only consuming crystals, but also wasting resources. It is better to let the population develop naturally, and this speed will definitely not be slow.

Du You found that after the territory level was full, the offspring born to the commoners of the territory also belonged to the people. Moreover, the somewhat imbecile minds of the lords have begun to recover gradually, and it is only a matter of time before they return to normal, at least.

But the talent of the lords is still suppressed, and it may not be solved until the whole world is controlled, and there is no way to change this. There is no limit to the total number of troops, and the same is true for battle pets. Du You plans to immediately recruit all the demonic beasts that he couldn't summon this month, and these are all valuable combat power.

Similarly, Du You also found that the column of his territory area was gone, which showed that his territory was now unlimited. But it doesn't mean that you can build your own buildings at will.

Building functional buildings today is just like the buildings in the games in the past. As long as it is within a certain distance of other buildings, it can be built. Of course, this can be regarded as a disguised territorial size limit.

If there were no such restrictions, then the territory of the academy would have been able to blossom all over this world long ago. Now that the territory has Blue Crystal Coins income, the only drawback is that the daily consumption of Crystal Coins has also increased.
