In addition to class buildings, some other details have also been improved. It's just that their own civil buildings are all third-order, and none of them have reached the fourth-order so far.

On the one hand, it is because he does not have much investment, and on the other hand, it also shows that it is really difficult for these civil buildings to enter the fourth order. The higher the level of civil buildings, the more difficult it is to manufacture. Du You is in the market, so far there is no civil architectural drawing above the fourth order.

Sand Snake Cave (4th Order):

Temporarily summon level 23 sand snakes when the territory is attacked, with a number of 3000. Two-headed sand snake level 37, number 300. The sand snake exists for 24 hours and has a cooldown of 24 hours.

The Sand Snake Cave has finally been upgraded to the fourth order, but the essence has not changed, and it is still just a building for auxiliary defense. Although the level of the sand snakes has increased, Du You has tried it, and sure enough, the strength of these sand snakes has become very poor.

For some more powerful enemies, it is not impossible to challenge or even challenge at the next level. As the level increases, the effect really gets worse and worse.

At the same time, the city walls and some arrow towers have also been upgraded to the fourth order, but this effect is still in the past. The blueprint of the city wall was given to him by the academy, and the arrow tower was upgraded by himself with the upgrade blueprint, so the effect did not decrease.

In the end, Du You also found that his alchemy factory had been upgraded to the fourth order, and two kinds of potions had also been added.

Fishman Flask (2nd Order): After use, it can breathe underwater to fight, and the effect lasts for 8 hours.

Frost Pill (Tier 4): After use, the self's attack is blessed with the power of ice, and the attack resistance to the ice attribute is increased.

The Fishman Elixir should be used to correspond to underwater battles, after all, the opponent is the Hanhai Kingdom, and many times it is necessary to go into the water to fight. There is no such thing as a submarine in his territory, so he can only rely on his own troops.

Speaking of which, it is also very important to be able to be afraid of the Hanhai Kingdom and dare to go to war directly with the Hanhai Kingdom. It is only the height of the second order, and in the fourth order alchemy factory, the production efficiency is very high.

As for the Frost Pill, Du You didn't know where this thing came from, but it had a strong effect on warriors. Du You plans to bring some back when the time comes, and use them to sell to see how the effect is.

For the next few days, Du You was busy running back and forth between the earth and the city of mountains. There are too many things on the other side of the earth, so it is impossible for Du You to leave the city of mountains and go to other places for training. After three days passed on the Yalan Continent, the building of the Mage Tower was finally constructed.

On this day, Du You and the two sisters are waiting here. The tall mage tower had just been built, and it was immediately recognized by the territory. Because it is a special building of its own, it does not need Du You to upgrade it himself.

The Mage Tower itself began to evolve and advanced, and countless elements in the void were gathered. The mage tower, which seemed to have only one shelf, began to expand, getting bigger and taller, and the whole material changed from black and white to fiery red, and some parts directly burned into flames. The Flame Tower lived up to its name, and in the air, a cloud of fire slowly emerged.

When the tower was raised to the fourth order, Du You suddenly found that shadows under the earth slowly stood up. A large number of fire elements were gathered, and there were more and more tall figures.

These figures were exactly what the flame giants looked like, and one by one they quickly grew to a height of more than eight meters. According to the rules of the Flame Giant's world, the strength of this Flame Giant has reached the fourth order.

"Master, open the panel and take a look. Lin Yushi was the first to shout.

Du You nodded hurriedly: "That's right, you should take a look." ”

"Show me, and I'll see it too. Aisha jumped over, but unfortunately she was a little short. Although Sha Liya was also very anxious, she didn't show it, and still stood by Du You's side dignifiedly.

Du You opened the panel and showed it to others with a smile.

Flame Tower: Resists the pressure of the world, and increases the talent of civilians in the realm.

Comes with Fire Cloud Wonder: Condenses fire elemental fire clouds above the tower to increase the speed of fire attribute cultivation. During a realm war, Fire Cloud will automatically provide a Stream Fire Attack.

Comes with Flame Giant Guard: The province has 1000 Flame Giants, which is equivalent to the territory level, and cannot leave the territory range.

Mage Tower Outbuildings: None

"Look, that's what the Mage Tower is capable of. "In the future, with the Mage Tower, my own people will no longer be suppressed, and the speed of cultivation will definitely be faster and stronger than those aborigines.

Moreover, intelligence will not be suppressed, and management talents in their own territory will continue to emerge. There is no need to worry about territorial management talents as before, and there are always some management talents under this huge base. In the future, Sharia and Luo Jia will also be able to make it easier, and the development of the territory will be faster.

As for the Fire Cloud Wonder, it is used to strengthen the cultivation of the flame attribute, and it also has the ability to fight back.

"Sister Shariya seems to be a flame attribute, so the benefits are great. "Although Shariya has changed her profession and started to cultivate the profession of Charmer, she is still based on fire attributes.

Sharia smiled reservedly, not paying attention to any of this. Since managing this territory, Sharia's mood has gradually come out of the previous haze and become more and more cheerful.

"These thousand flame giants are the best. It is not part of our territory's own combat power, but it is a giant whose combat power far exceeds that of normal creatures. With just a thousand fourth-order flame giants, I don't think there is anyone around here who can deal with us. It's a pity that these flame giants have no way to command and hide, so they can only be exposed. ”

Indeed, it is strange that there are so many flame giants walking around the territory area, and no one has noticed.

The Hanhai Kingdom will be more vigilant, but the Shenyan Empire also needs an explanation. This is not an ordinary human soldier, but a flame giant, and the most important thing is that there are too many of them at once.

This number is more than the fourth-order military strength exposed before the city of mountains, which is enough to dominate the entire southern frontier of the empire, and it is a force that has a huge influence on all major forces, how can the Shenyan Empire ignore it.

"Just explain it to them casually, anyway, we will start a full-scale war with the Hanhai Kingdom next, I think the empire likes to see this kind of scene. By the time our territory is upgraded again, we will soon have a large number of Tier 5 troops. ”

It is true that the empire has sixth-order powerhouses, but there are certainly not many, and they can't be easily moved. At that time, the southern coast of the empire was its own world.
