On the third day of Lin Mo's return to the surface world with his dragon companion Gold Coins, a batch of brand-new firearms was handed over to the Underground Free Federation by Dragoon Magic Industries. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

120 light howitzers of 155 mm caliber, 20 x 8 x 130 mm 24-barrel rocket launchers, light tracked armored vehicles of 12.7 mm caliber alone, 500 80 mm mortars, and ammunition of 20 bases.

Dragoon Magic Industry takes into account the special geographical environment of the underground world in advance, and the firearms provided by these firearms have certain restrictive adjustments to parameters such as elevation angles, and the ballistic curve is limited to a height of less than 9000 meters, so as not to affect the rock formations of the dome.

These powerful new firearms can just make up for the disadvantage that the eleven intelligent races in the underground world are not strong enough to confront the "Zachari" parasitic creatures head-on.

In addition to these, 60 12.7 mm sniper rifles, 50 40 mm sniper grenade launchers, 40 100 mm rocket launchers, 10 high-power laser guns, 20 400 mm electromagnetic accelerator mortars, 10 12.7 mm six-barrel Gatling guns, thousands of high-explosive mines, and a flying wing, including 54 Thang Long-2 propeller fighters and 4 A-1 Brontosaurus Attack aircraft and 8 AH-1 "Sparkling Dragon" helicopter gunships are supported by ammunition for their matching.

The soldiers of the Free Federation did not think of it from the beginning when they first came into contact with these firearms from the technology tree of the earth's civilization, and even thought that the "hammer head" of the "heavy hammer" of the 155 mm caliber howitzer was more than beautiful and lacked lethality.

When the deafening noise had dissipated, they could see the huge crater of the impact point, and the lethality of the dead and wounded creatures, and all the aliens shut their mouths in unison.

The Free Federal Councillors, who have gradually learned to wield power and taste the sweetness of freedom, are glad that they have a powerful and reliable partner, if Dragoon is on the side of the false gods. For the eleven intelligent races in the underground world, it is tantamount to annihilation, and I am afraid that they will never want to get rid of the fate of being enslaved and fooled, and completely sink.

For the first time, new firearms were limited to the underworld, including those that were given to the Free Federation, each with its own unique number, and many of them had hidden locking mechanisms, which only required an electromagnetic signal to completely disable the weapon and turn it into a virtual scrap metal.

Even if the Free Federation wants to be a white-eyed wolf, it rebels with the firearms of Dragoon Magic Industries. The part of the firearms in the hands of the soldiers of the Security Bureau is also enough to easily crush the other side, not to mention that without air supremacy, everything is false.

In this way, even if Lin Mo and the Golden Dragon leave, the alien races of the Free Federation and the soldiers of the Security Bureau of the Underworld will have enough force to contend with the "Sachari" forces of the surrounding God Kingdom.

It does not take much time to get to grips with these firearms, and seven days is enough for the soldiers of the Free Liberation Army and the Security Bureau of the Free Federation to become proficient in their operation, and they can use most of their lethality by firing one or two base training shells.

The Security Bureau soldiers were equally surprised by the power of these firearms, but they did not see them as killers as the aliens of the Free Federation. In their opinion, the strength of the individual itself is the foundation, and the strength of battle qi, magic, and secret art is the real strength.

For the firearms that got in hand. Just as an auxiliary tool, it can save a lot of energy for future battles and help the Heavenly Supreme Lords to divert the attention of "Zachari".

Dragoon's jet project, led by three makers and twenty-one high-level alchemists, has successfully built the first prototype of the Crystal Jet Engine. Soon there were second, third, and fourth.

The fact that the development of a propulsion engine, which usually takes years, was able to achieve initial results in just a few days was all thanks to a golden dragon.

After feasting on a pile of metal, the rough embryo of the Crystal Energy Jet Engine evolved from the gold dragon coins. The step-by-step fine adjustment like a cat and a tiger, relying on the innate ability to reach the nanometer level with precision, saved a lot of time and energy for these twenty-four alchemists.

These four prototypes are not exactly the same, there are obvious differences in some components and even structures, each represents four different design concepts and preferences, and the final one is better or worse, and it needs to go through various technical verifications before the final result can be judged.

The heat engine test of the crystal energy jet engine was in an empty and tall warehouse, and layers of enchantments and spell shields were laid near the engine body, and even the destructive power of a 1,000-kilogram high-explosive aerial bomb could not completely destroy these pre-prepared defensive means.

The Crystal Jet Engine Heat Engine was tested in a tall and empty warehouse, with layers of enchantments and spell shields laid near the engine, making it difficult for even the shock wave of a 1,000-kilogram aerial bomb to destroy these defenses.

The maker who led the verification of the technology glanced at Qi Fei and Lin Mo, who were shrouded in a three-sided light spell shield not far away, and turned his head and nodded to the alchemist who was controlling the engine.

"Ready to ignition!3, 2, 1! Start the engine!"

As soon as the words fell, the alchemist in front of the console suddenly pressed a bright red button, and then he heard a buzzing sound that quickly changed from weak to strong, and the entire warehouse seemed to be driven by this louder and sharper sound.

As the first to test, the No. 1 Crystal Solar Jet Engine burst into red light at the end, and suddenly spewed a violent and strong air current, passing through the cavity made of a round of metal rings at high speed.

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

In terms of hardware, the jet project team is no longer inferior to the engine research institute of the earth civilization, and the gold dragon has almost copied all kinds of equipment in the original class, and easily evolved it temporarily.

"The theoretical minimum speed is reduced by 5%...... Confirm the minimum threshold and re-ignite...... Increase the output by 1% per second to 120% of the theoretical value, pay attention to the observation curve, and confirm that the resonance frequency ......"
