"Why isn't it garbage?" Emperor Shi Tian angrily pointed to a picture and said: "Look at this design drawing, there are no buildings in the city, all of them are big trees, I admit, these tree houses are exquisite and beautiful, and they are big enough, after they are completed, the whole city is like a sea of flowers, it is indeed beautiful, but there is not even a city wall, how to defend against foreign enemies?"

"What do you know?" the little angel said unconvinced: "This kind of tree city has a very strong defense, the grass and trees covering the city can be turned into a killing weapon at any time, the shrubs can be woven into a thick, tall city wall, the rattan on the city wall can attack, trap people, the city wall itself also has an extremely strong recovery ability, even if the roots are uprooted and burned, it can be quickly recovered, unless all the vines and trees in the entire city can be removed." In addition, all the giant trees in the city can be turned into tree people to fight, and the whole city is a large military camp, whoever comes and who dies, and even when they can't fight, they can escape collectively. ”

"Then what's the use of you giving me this broken blueprint?" Emperor Shi Tian said angrily, "Do I have the conditions to make such a thing?"

"This~" The little angel was speechless for a moment.

"And these sculpture cities, there are no defensive buildings, no walls, no towers, not even a lookout post, only sculptures everywhere, called the city of art, which can be used to defend against the enemy?"

"Those sculptures are powerful magical defense towers, each of which is so powerful that it can be transformed into alchemical golems when necessary, and can be directly involved in battle. The little angel said weakly: "Of course, you don't have the conditions to get these now." ”

"Then what's the use of you giving me these broken blueprints?" Emperor Shi said helplessly.

"You want the best architectural drawings, and of course I can only give you the best. The little angel argued.

"Okay, okay, it's my pot. Emperor Shi Tian smiled bitterly: "Can you take some simple drawings, with the drawings that I can build at my current level." ”

"Yes, wait until I choose. The little angel hurriedly did it, and then showed dozens of drawings.

After Emperor Shi Tian looked at it, he frowned and said: "It's not very suitable, these drawings are still strange, and there is no strong protective ability on the surface, if I guessed correctly, they should be matched with special magic weapons to play a role, right?"

"It seems like this, in fact, everyone's architectural drawings have to consider their own situation, according to their own troops, and choose and design. The little angel said helplessly: "Your class belongs to the type that has never appeared, cavemen crossbowmen, and I really can't find a suitable castle blueprint." ”

"It seems that I still have to design it myself~" Emperor Shi Tian closed his eyes speechlessly.

Emperor Shitian's life can be described as magnificent, from orphans, to mercenary scouts, to mercenaries, interstellar pirates, to the establishment of a dynasty, and the achievement of the emperor, which can be described as wonderful.

During this period, Emperor Shi Tian fought countless battles, and although the later period was an interstellar war full of interstellar warships, the early stage was basically an offensive and defensive battle on the ground.

This also makes Emperor Shi Tian very familiar with the defense of castles, he has not only built it with his own hands, but also led the army to fight countless battles, and among these countless battles, Emperor Shi Tian's most impressive is undoubtedly the multi-layered fortress.

The so-called multi-layered fortress is a prismatic castle stacked on top of each other.

To put it simply, a prismatic castle is a castle with triangles connected together, and this kind of castle has a good advantage in defense.

Attacking one corner of the prismatic castle will be flanked by the two next corners, and the frontal attack of this corner will make the attacking troops flank from both directions, making it very difficult to defend.

And if you want to attack the depression of the prismatic castle, you have to withstand attacks from the front side, or even from the rear, and there are enemies on all sides, so you can imagine how many people will die.

The prismatic castle itself is very protective, and if you add a few more layers to him to form a ladder-shaped multi-layered bast, the protective power will be increased exponentially.

Even if you try your best to capture the first layer, it will be useless, but you will be attacked by the second layer, as well as direct fire from other surrounding layers.

The most perverted place of the multi-layer fortress is here, the next layer is unconcealed for the previous layer, there is no dead end, you can only be beaten passively, and you have to withstand attacks from all directions, even from behind, so even if you capture the lower layers, you can't hold it at all, which is equivalent to dying in vain.

In Emperor Shitian's impression, relying on crowd tactics to attack multi-layered fortresses from the front is basically an act of seeking death.

Unless it is destroyed from within, or simply razed to the ground with the multi-layered bastions, there is basically no way to attack it head-on.

In addition, in addition to the city walls, the multi-storey bastion can also build some tall defensive structures behind the city walls, so that it can cross the city walls and launch direct attacks on enemies outside the city.

With multiple layers of bastions in front of you, you can safely attack from the rear without having to think about defense.

In this way, a two-layer firepower network has been formed, both against the air and on the ground, and has extremely strong defensive capabilities.

With these in mind, Emperor Shi found some architectural techniques from the Flame of Wisdom to further refine the details of the multi-storey fortress and high-rise defensive buildings.

At this time, Emperor Shi Tian discovered another metamorphosis ability of the fire of wisdom, that is, he greatly improved Emperor Shi Tian's intelligence.

Emperor Shi felt that the Flame of Wisdom itself was like a supercomputer, which allowed Emperor Shi Tian to complete extremely complex graphic designs and all kinds of calculations, and store them all without worrying about forgetting them.

It's just that when performing this kind of operation, it will continue to consume Emperor Shakti's magic and spiritual power, so after only a few hours, Emperor Shakti is tired and has to fall into deep meditation and deep sleep.

It took two days for Emperor Shi Tian to complete his design, and then, without feeling tired, he immediately summoned Aladdin and two earth mages to start building in his territory.

When everyone came to the field 500 meters away from the magic pool, Emperor Shi Tian first raised his hand and drew a line in the air, and under the mana agitation, there was an extra scratch sixty or seventy meters long on the ground.

Then Emperor Shakti said, "With this line as the center, I will build a city wall, Aladdin, please use fossils as clay spells to make enough earth for me." ”

Aladdin is also very intelligent, and after thinking about it for a while, he pulled out the Ten Thousand Magic Heavenly Knife, and with a slight wave, he would instantly hit five fossil mud spells.

All the spells were dozens of meters outside that boundary, and there was nothing to see on the surface, but Emperor Shi Tian could feel that the spells had taken effect, and the originally hard stone had turned into soft earth.

Without any nonsense, Emperor Shi Tian immediately took out the Earth Spirit Mother Bead and used it as a medium to perform the soil control technique.

As an earth-based magic weapon, in addition to storing and extracting earth-based spiritual power, the Earth Spirit Mother Bead also has one of the biggest features that it can increase the power of earth-based spells.

For a small spell like Earth Control, the Earth Spirit Mother Bead can increase its power several times.

Originally, Emperor Shakti could build a maximum of five meters high, ten meters long, and two feet thick earth walls.

However, under the blessing of the mother beads of the soil forest, the soft soil automatically converges on that line under the control of invisible forces, forming a very standard, five-meter-high, more than 30-meter-long, and three-meter-thick mud city wall.

After the city wall was formed, there was no need for Emperor Shitian's order at all, Aladdin's eyes flashed, and he immediately made a move, using the Ten Thousand Heavenly Knife to release five spells that turned mud into stone.

As the earthy yellow glow dissipated, the originally soft earth walls turned into pitch-black stone walls, which were not only strong in themselves, but also glued to the stone ground below, as if they were born as a whole.

Obviously, this is Aladdin's work, and as an all-rounder, he naturally knows how to build the strongest walls possible.

Just for the protection of this city wall, the protection of Emperor Shitian's territory can be increased several times.

But this was obviously just the beginning, and Emperor Shakti then kept drawing lines, and Aladdin kept casting fossil clay spells off the line.

Then the Emperor Shi Tian turned the newly produced soil into city walls, each of which was oblique, with a total length of about 60 meters, and spliced into triangles with each other to form a prismatic city wall.

The magic pool is backed by a heavenly pillar more than ten kilometers thick, so only a semicircular city wall is needed to complete the closed defense system, which allows Emperor Shi Tian to save half of his workload.

Moreover, Emperor Shi Tian was not greedy, and only drew a range of 500 meters, so in only half a day, the first prismatic city wall was built.

Emperor Shakti made two large openings in two hollows, and then instructed the cave people to start building a strong wooden gate.

Subsequently, Emperor Shi Tian looked around and found with great satisfaction that he not only had a diamond-shaped city wall defense, but also a moat without water.

This moat was excavated by Aladdin's fossil for a mud spell, and at the beginning, he deliberately released this spell outside the city walls, and then the walls were built, and the pits that took the dirt were connected into a moat.

Although there is no water in this moat, and it is only a few meters deep, it can only be considered a relatively large ditch at best.

However, this thing still has a certain amount of protection, because when the enemy rushes into the ditch, it will face direct fire from the wall, and when it climbs up the ditch, the speed will also slow down, and it will need to withstand more attacks.

The most important thing is that the large engineering equipment is basically scrapped, don't expect the huge building truck to climb out of the ditch.
