On the third day after Lin Mo and his mount dragon partner returned to the ground world, a batch of brand new firearms were handed over to the hands of the Underground World Free Federation by the Dragoon Magic Industry.

120 155mm caliber light howitzers, 20 3x8 equipped with 130mm 24-tube rocket launchers, single-mounted 12.7mm caliber light tracked armored vehicles, 500 80mm caliber mortars, and 20 base ammunition.

The dragon magic industry takes into account the special geographical environment of the underground world in advance. The firearms provided by them have certain restrictions on parameters such as elevation angle. The ballistic curve is limited to a height of 9,000 meters to avoid affecting the rock formations of the dome. God knows what kind of disaster will happen after this dome is destroyed. After all, this is the underground world, and there is really a saying that it breaks the sky.

These powerful new firearms can just make up for the disadvantage that individuals of eleven intelligent races in the underground world are not strong enough to face the "Sagali" organisms head-on.

In addition to these, they also brought 60 12.7mm caliber sniper rifles, 50 40mm caliber sniper grenade launchers, 40 100mm caliber rocket launchers, 10 high-power laser guns, 20 400mm caliber electromagnetic acceleration mortars, 10 12.7mm caliber six-barrel Gatling machine guns, thousands of high-explosion mines, and a flight wing, including 54 "Shenlong-2" propeller fighters, 4 A-1 "Blade Dragon" attack aircraft and 8 Ah-1 "Sky Dragon" armed helicopters to match their ammunition support.

When they first came into contact with these firearms from the Earth's civilization and technology tree, the soldiers of the Free Federation did not agree with it from the beginning, and even believed that the "heavy hammer" of the 155mm caliber howitzer was beautiful and had insufficient lethality.

After the deafening noise dissipated, they saw clearly the huge craters that were bounced, as well as the lethality verification creatures of the casualties and injuries. All the alien races closed their mouths together.

The Free Federal MPs who gradually learned to control power and tasted the sweetness of freedom are all grateful that they can have a powerful and very reliable partner. If the Dragoon Magic Industry stands on the side of the pseudo-gods, it will be a catastrophe for the eleven intelligent races in the underground world. I am afraid that they will never get rid of the fate of being enslaved and fooled and completely sink into desolation.

The new firearms that were popular for the first time were limited to the use of the underground world, including the part that was supported to the Free Federation. Each piece has its own independent number. Many also have a locking mechanism. Only an electromagnetic wave signal can completely ineffective the weapon and become a waste of scrap iron.

Even if the Free Federation wants to be an ungrateful wolf and rebel with the firearms of the Dragoon Magic Industry, the firearms controlled by the security soldiers are enough to easily crush the other party, not to mention that without air supremacy, everything is false.

In this way, even if Lin Mo left with the Golden Dragon, the alien races of the Free Federation and the soldiers of the Security Bureau of the Underground World could have enough force to compete with the "Sargali" forces in the surrounding divine kingdom.

It does not take too much time to initially master these firearms. Seven days are enough to make the soldiers of the Free Federation's Free People's Liberation Army and Security Bureau proficient in operation. If you knock out one or two training bullets of a base, you can exert most of their lethality.

The soldiers of the Security Bureau were also surprised by the power of these firearms, but they did not regard them as killer weapons like the aliens of the Free Federation. In their opinion, the strength of individuals is the fundamental, and the power of war energy, magic and secret techniques is the real power.

The firearm you get is just used as an auxiliary tool, which can save a lot of effort in future battles and help the Supreme Master of Heaven to restrain the attention of "Sargali".-

Dragoon Magic Industry, a machine project jointly participated by three creators and twenty-one advanced alchemists, successfully created the first crystal energy engine prototype, and soon there was a second, third and fourth.

The reason why the development of the promotion engine, which is usually over several years, can achieve initial results in just a few days is all due to a giant gold dragon.

After a full meal of metal, the gold dragon gold coins evolved into the crystal energy engine's rough embryo, which was refined and adjusted step by step like a cat and tiger. Relying on accuracy, it can reach the nano-level talent ability, saving these twenty-four alchemists a lot of time and energy.

These four crystal energy engine prototypes are not exactly the same works. There are obvious differences in some components and even structures. They each represent four different design concepts and preferences. In the end, which one is better or worse still needs to be verified through various technical verifications before the final result can be judged.

The thermal engine test of the Crystal Energy** engine is in an open and tall warehouse. Layer barriers and spell shields are laid near the engine body. Even the destructive power of a 1,000-kilogram high-explosion aviation bomb is difficult to destroy all these pre-prepared defense methods.

The thermal engine test of the Crystal Energy** engine was set up in an open and tall warehouse, with layers of barriers and magic shields placed near the engine. Even the shock wave of a 1,000-kilogram aviation bomb was difficult to destroy these defense methods.

The creator who led the technology verification glanced at Qi Fei and Lin Mo who were shrouded by three-sided light-type magic shields not far away, turned his head and nodded to the alchemist who controlled the engine.

"Prepare to ignite! 3,2,1! Start the engine!"

As soon as he finished speaking, the alchemist in front of the console suddenly pressed a bright red button, and then he heard a buzzing sound from weak to strong. The entire warehouse seemed to be trembling with the increasing louder and sharper sound.

As the first test, the No. 1 crystal energy engine was red in the end, and a violent strong air flow suddenly appeared, passing through the cavity composed of a round metal ring at high speed.

As the hot and wild air flow continues to gush out, a large amount of data is collected by various sensors and summarized and input into a special small machine.

In terms of hardware, the ** machine project team is no less than the Engine Research Institute of Earth Civilization. The Golden Dragon almost copied various equipment and easily evolved it temporarily.
