In addition to expanding the magic moss, another contribution of the Yuelan Holy Maiden to Emperor Shi Tian was to accelerate the cultivation of spirit beans.

After half a year, that silver-level spirit bean had grown and had produced a lot of pods.

Just the day before yesterday, after the pod cracked, three yellow plump beans popped out of it, adding up to exactly ninety-nine eighty-one beans.

They were rated as a bronze upper grade, apparently degraded by one level.

However, Emperor Shi Tian didn't care, but let the Holy Maiden of Yuelan continue to plant, striving to expand the population.

Because Emperor Shi Tian is really too curious about the legendary immortal arts, scattering beans into soldiers. I'm really looking for a chance to give it a try and see if it can be rolled out on a large scale.

In addition, in the past six months, the biggest change is probably the dog-headed aluminum bat, with the support of a large amount of aluminum ore and magic water, these guys have also swelled to 100,000 numbers.

Once it takes off, it will really cover the sky and the sun, not to mention the combat effectiveness, just looking at this scene like a locust transiting, it will be very terrifying.

In fact, the dog-headed aluminum bat is really very powerful, in addition to his own strong combat effectiveness, the most important thing is that this guy, as a flying soldier, can have a weight of 200 kilograms.

The most important thing is that as a silicon-based life, the doghead aluminum bat has very strong endurance and strength.

Emperor Shi Tian once did a test, without the blessing of spells, the dog-headed aluminum bat can fly 2,000 kilometers with full weight, and it must sit down and rest.

With enough auxiliary spells, the dog-headed aluminum bat can even fly a distance of 10,000 kilometers, which is really shocking.

Don't think 200 kg is very small, but don't forget that there are a lot of dog-headed aluminum bats!

There are thousands of such things, 10,000 dog-headed aluminum bats, which can transport 2,000 tons of materials or personnel at one time.

In addition to transporting supplies and personnel, the doghead aluminum bats can fully play the role of a light bomber.

Emperor Shi even developed a special bomb weighing 50 kilograms for them.

Each dog-headed aluminum bat can easily lift four of these aerial bombs with two feet and throw them on the enemy's head.

A 50-kilogram bomb is very powerful, although there is no way to seal a fourth-level spell with ordinary materials, that is, a spell with a silver level.

However, in the case of third-level spells, it is possible to carry out a double seal, that is, to release two spells at once.

This is terrifying, especially the blaster spell of explosive power, if two detonate at the same time, their power will be superimposed on each other, becoming very terrifying, almost comparable to a fourth-level spell.

A dog-headed aluminum bat can airdrop four, 10,000 can cut out 40,000, absolutely, you can carry out a carpet bombing.

Emperor Shi felt that as long as his bomber unit was dispatched, he could basically block people and kill people, and Buddha block and kill Buddha!

If there is a war with the Four Heavenly Kings at this time, Emperor Shi Tian will not even bother to use any conspiracy and tricks, and will directly bombard it all the way with a dog-headed aluminum bat, and he will be able to blow up the Four Heavenly Kings into four pieces of!

In order to cooperate with the dog-headed aluminum bats to carry out bombing missions, Emperor Shi Tian even specially assigned a lot of auxiliary mages to them, and formed four special bombing mage groups, all of which were issued flying magic carpets.

In addition, Emperor Shi even reduced the production of rocket artillery and went all out to produce 50 kg aerial bombs.

Fortunately, in these years, Yaslian has not been idle for a moment, and has made a total of more than 3,000 tentacle Ji.

These tentacles are not idle, and most of them are responsible for operating alchemy equipment and producing all kinds of munitions.

The most important of these are aerial bombs and 250 mm heavy guns.

The 250 mm caliber heavy gun, directly named 250 by Emperor Shi Tian, is a new type of artillery that took three months of research and development to complete.

The reason why this kind of bulky big guy was developed was because in the last defensive battle, Emperor Shi Tian found that he really had no good way to take the other party's rough-skinned siege beast.

If it weren't for the fact that these siege beasts were too sharp, Emperor Shi Tian, with more than 20 lines of defense, would be able to consume the troops of the Four Heavenly Kings, and it would be possible to annihilate them all at that time.

In order to prevent such a thing from happening again, Emperor Shi Tian immediately ordered the development of heavy artillery after ending the war and starting to recuperate, and there was only one requirement, which must be able to reach the silver level of lethality, and the weight should not be too large, at least it could be carried around by the alchemy carriage.

Aladdin, Yaslian, Dragon Cannon Ji, and even Danmaku Ji were all involved in the research work on heavy artillery.

After several months of hard work by four people, they finally came up with a qualified product, which is the current 250 heavy gun.

The 12-meter-long cannon has a very simple gun carriage, all made of magical metal, and the barrel is engraved with dense magical patterns.

His shells, with a diameter of 250 millimeters and a length of 1.3 meters, weighed a staggering 300 kilograms.

All of them are sealed fourth-level spells, including the Great Explosion of Fire Qi, the Thundercloud Storm of the Thunder Formation, the Ice Spear Rain of the Ice Formation, and the Meteor Fire Rain of the Earth Formation.

These spells can basically cover an area of several hundred square meters, and the lethality is also greatly increased, which is especially suitable for bombing those dense troops.

Of course, such a cannon is also very heavy, nearly more than 20 tons, and it has no power, so it can only be mounted on an alchemy carriage and run around.

And each link wagon can carry 30 shells, which is basically not enough. Therefore, it is necessary to send an additional logistics vehicle to transport artillery shells.

When the cannon is fired, the alchemy cart must fall to the ground, and it cannot withstand the recoil when it floats.

Huge cannonballs will be filled with professional orc gunners.

These three-meter-tall big guys are all bronze-level orc warriors with fighting spirit, and the 300-kilogram cannonball is just a toy in their hands, which can be easily stuffed into the cannon chamber.

In this way, the rate of fire of the cannon can be guaranteed, with the reloading speed of the orcs, one shot can be fired in three seconds, and even 20 shots can be fired in one minute.

Of course, at such a speed, if the cannon is fired, the barrel will easily heat up and deform, and it is very easy to be dangerous.

But it doesn't matter, you know, this is a magical magical world, and as long as there is a mage, any problem can be solved.

Here, for example, Aladdin's solution is to equip an ice-based mage to cool down the barrel at any time.

In addition, this mage can also be used to aim and correct cannons.

Because mages have a lot of handy spells, such as Eagle Eye for long-distance observation, where cannonballs land, and their powerful computing power, which can calculate the trajectory and movement speed of enemies, which makes them the best cannon commanders.

A bronze mage, with a 250 heavy cannon, can basically exert the combat power of a silver mage, and it can be regarded as a big profit anyway.

Generally speaking, each 250 cannon is composed of a mage cannon commander, plus four bronze orc loaders, and they will also be equipped with two alchemy carriages, one to carry cannons and one to carry cannonballs, all of which add up to one combat unit.

It's a pity that this is an underground world, so the range advantage of the 250 heavy cannon is not well reflected.

The maximum range of the 250 heavy cannon can reach 50 kilometers, and in the underground world, it can only reach 15 kilometers at most.

There are even times when the dome is too low, so the heavy artillery has no way to use the means of projectile, and can only carry out direct and flat fire, and the firing range at this time is only five kilometers at most, which can be called pitiful.

But in any case, the 250 heavy artillery has become a big killer in the hands of Emperor Shi Tian, and even a favorite, so it is natural to speed up the production, so far, 300 have been equipped.

Emperor Shi Tian really wanted to pull them out to slip around, but unfortunately there was no chance.

Because anyway, after the failure of the alliance, Emperor Shi Tian became the uncrowned king of the first layer of the underground world, and basically no one dared to find trouble.

Emperor Shi even used his residual power to challenge the Four Heavenly Kings and captured several of their cities.

However, the four heavenly kings, who were originally extremely arrogant, all became good babies at this time, and even angry bags, except for a protest, nothing happened.

Even when they were under attack, they took the initiative to evacuate the people in the city to avoid unnecessary losses.

Even if Emperor Shi Tian did not close the other party's teleportation array, the other party could send reinforcements, and they did not have the courage to fight with Emperor Shi Tian again.

In addition to the reason why he was cleaned up by Emperor Shi Tian last time, there was another reason, that is, the Four Heavenly Kings had finally reached the deadline and were forced to enter the second layer of the underground world.

The current Four Heavenly Kings, basically, there are only empty shelves left on the first layer, and the main forces are all fighting on the second layer, and they are trying to find a way to lay a solid foothold for themselves.

If you change people, I'm afraid you will feel that you are not a good man.

But Emperor Shi Tian has no such garbage thoughts at all, and his motto is to take advantage of your illness to kill you.

Therefore, after Emperor Shi Tian tried out the reality of the Four Heavenly Kings, not only did he not stop, but began to encroach on their territory even more.

No, just when Emperor Shi Tian was satisfied with the retraction of the Divine Dragon Dun Armor, forming a set of mighty armor, and wearing it on his body, the little angel ran over and said: "Lord, good news has come from the front line, and we have captured a main city belonging to the Overlord Flower." ”

"Cut~" Emperor Shi Tian sneered disdainfully, and said: "I'm afraid that when I go, the people will have already fled, right?

"I'm sorry to tell you, we really haven't gained anything, when the overlord flower left, it took everything that could be taken, the empty warehouse can starve to death of mice, and all the mobile buildings are not left. The little angel said angrily: "This woman is really stingy!"
