"Let's melt in first." Ryuji quickly made the decision to integrate this land into the former half-plane first, and when his family was ready to transform the underworld ecosystem, they could also transform it together.

Otherwise, when the plane upgrade is completed, the land will be integrated, and it will take a long time to deal with this matter.

At that time, there will be another piece of his plane missing, and that will be unpleasant.

After arranging the plane consciousness away, Ryuji returned to the Scarab Secret Temple, where there were still many things waiting for him to tidy up.

In the contents of the treasure chest this time, Ryuji noticed a silver statue, which looked like a tall castle, the size and color were so conspicuous among all the statues, Ryuji picked up the castle statue at first sight.

"It's a blueprint for a city, and if it is, it would be great."

But the moment he picked up the statue, Ryuji knew he was thinking too much.

[Eye of the Dead, Alpine Castle Blueprint: The core building of the City of the Dead, the upper level is 7, the number of uses is 7 times, and a Alpine Castle can be built in a designated location. 】

[Alpine Castle: As the most core building required for the advancement of all cities, Alpine Castle has a very high status in all cities, and the Alpine Castle in front of it has been affected by some and has become an exclusive promotion building for the City of the Dead. 】

[Eye of the Dead: Only undead troops, minions, and professionals are allowed to enter the Alpine Castle to advance to the ranks.] 】

[Note: Undead who enter the Alpine Castle rank must be level 4 or 9 and have enough embellishments to enter the Alpine Castle to become a level 5 or 10 high-level class.] 】

Looking at this thing, Liu Zhi couldn't help but sigh.

This is a good thing, Liu Zhi knows that the troops under his command actually have a promotion direction.

For example, the Eagle Samurai can be promoted to the Eagle Samurai after level 5.

But how to advance, Liu Zhi has no idea at all.

Now it seems that this mountain castle was used for the advancement of the undead troops.

As long as the level of the undead troops under Liu Zhi has reached the requirements, for example, he has reached level 4 and has reached level 5 experience, then he can enter the mountain castle to advance.

This is a good thing for Ryuji.

A large part of the reason why he had all kinds of problems before was that his subordinates were cannon fodder, and neither were the elite troops.

There are only a few high-level troops he can take out, and if he really wants to be on the big battlefield, it is useless at all.

In this regard, Yanoji carefully read the description of Takayama Castle.

There are seven levels of this Alpine Castle, and at level 1, you can put seven types of troops into it at the same time, and then add one more class to each level, and at level 7, a total of 13 classes can be promoted inside the Alpine Castle.

Each class can only enter according to its own team formation, and troops without an establishment will not be able to enter the Alpine Castle rank.

Liu Zhi also agrees with this, although this is a little troublesome, and it can't be like other situations, when the experience is reached, people will be arranged, but this at least ensures the promotion of Liu Zhi's main force.

Liu Zhi thought for a while, and did not build this mountain castle on the side of the Hades Palace.

Instead, the alpine castle was built on the previous twisted passage, and at the same time, the gymnastics class gave a death order that this alpine castle must be built in the shortest possible time and promoted to level 7.

Ryuji knows very well how many undead he has under his command, and if all of these undead are successfully formed, it will be a large force, judging from the situation that once a week, 13 formations will advance together each time, and this side of Takayama Castle will be very busy for a period of time in the future.

After arranging the Takayama Castle, Ryuji's attention turned to the architectural plan that was placed with the Takayama Castle.

It was opened from the VIP package together, and although the quality was bronze, it looked like it was very interesting.

It was a half-finished model, and the whole model looked like a giant bowl, but if you looked closely, you could see that it was actually a gladiatorial arena.

It's just that this gladiatorial arena only has a middle field, but there is no place for the surrounding audience, which looks quite incomplete.

[Gladiatorial arena design drawing under construction: ordinary building, level cap 5, use 3 times, you can build a gladiatorial arena in a designated location. 】

[Gladiatorial arena under construction: An ordinary gladiatorial arena can put 300 people into gladiatorial battles at the same time, but one-on-one, or many-to-many, the winner of the gladiatorial arena will gain experience, and even form a new formation. 】

[Note 1: A strong player who wins 100 consecutive games in the Colosseum will leave a statue erected around the Colosseum, and the strongest attribute of the strong player who wins 1000 consecutive games will affect the battle inside the Colosseum.] 】

[Note 2: The number of people and the level of the Colosseum at the same time are affected by the level of the Colosseum.] 】

As can be seen from the explanation here, this gladiatorial arena is not as good as the Alpine Castle, but it can also be seen that this gladiatorial arena is the place where Ryuji's subordinates must come before entering the Alpine Castle.

Only after gaining experience here and increasing the level can I arrange for my subordinates to go to the Alpine Castle to advance to the ranks.

"This one is built on the outskirts of the Hades."

Liu Zhi glanced at the map of the Hades Palace and made a decision, he originally wanted to build the gladiatorial arena in the core of the Hades Palace, but there were several considerations that made him change his mind.

On the one hand, the Colosseum would have a large number of troops coming and going here every day, and it would be unrealistic to let some troops enter the core area of the Hades.

On the other hand, the gladiatorial arena will be built bigger and bigger, but the upper level of the Hades Palace will be smaller and smaller, and building the gladiatorial arena in the core of the Hades Palace is simply to seize the territory of other buildings.

Then there will be a large number of powerful troops on this side of the gladiatorial arena, if the Hades Palace encounters an attack, the gladiators here can quickly be in place, placed in the core of the Hades, and then want to run down, it will take quite a long time.

After the gladiatorial arena was lowered, Ryuji casually picked up the things that were placed next to the statue.

It was a boat in a bottle, which reminded Ryuji of what he had encountered in the previous game.

It's just that the boat in a bottle in front of me is a little different from the normal ship in a bottle, it is a dreadnought's ship in a bottle, and the dreadnought locked in the bottle can still move, and in the bottle it can actually make actions such as forward, speeding up, and firing a salvo of the main gun.

[Ship in a Bottle: Dreadnought: This is a ship that has mastered engineering, and whoever holds a ship in a bottle will get a +1 effect in shipbuilding, engineering, or artillery fighting. 】
