The Crusader's zero-element reactor cannon shot out a burst of blue light, and then the space in front of the hit underground creature distorted slightly, directly annihilating it into atoms.

"Withdraw!" The purpose of the investigation has been achieved, and it is obviously unwise to continue fighting. The troops fought and fought each other, and marched in the direction of the fortress.

- Underground Creatures Coalition -

"Gollum Purr ~ This group of fools actually dares to provoke those three ruthless worms, they are doomed!" Afinia looked happy, this group of iron turtles fell from the sky and occupied the home of the three of them, but the leaders of the other directions were unwilling to come out, so they could only fight and fight alone.

Soon, Aphnia receives a message from the other three leaders that they will be helping!

The fortress of the "Aeolus Throne" is facing an unprecedented crisis at this time.

- "Aeolus Throne" Fortress -

Day and night passed, and Liu Qi's technology unlocked 3 new branches:

1. Quantum information science

2. High-power working fluid plasma engine

3. "Chain" effect zero-element reactor

This time Liu Qi's technology points dropped from tens of thousands to 3,000.

Thanks to three new technologies, new units unlock manufacturing.

Class: "Yinglong I" fighter

Parameter: Shield: None

Armor: 30mm depleted uranium armor

Weapons: 50mm cannon*2

Engine: High-power working fluid plasma engine

Speed: Mach 3 (cruising) / Mach 5 (max)

Cost: 1000 resource points

Although it is only an airplane, the price is comparable to that of the "Radiant I" frigate, which shows its good power, and the 50mm electromagnetic cannon can definitely tear the biochemical shells of most underground creatures.

Then, Liu Qi is left with only one last problem: there is no airport!

So, the construction of robots is back to work. (EGR-1 type: Boss, I'm going on vacation!) Liu Qi: It doesn't exist. ）

Liu Qi really misses the underground race a little, after all, there are not a few technology points they provide.

The airport was manufactured in 10 hours, and the requirements for the airport were not particularly high for military products, after all, not every army has the conditions of the US imperialists' global airports.

The first batch of 20 "Yinglong I" was quickly assembled in 12 hours.

Two hours later, the light of the stars appeared again, but this time, far less pleasant than before.

"Mass organism approaching detected!" Central Wisdom Brain - Don't force a report.

"Meet the enemy immediately, I'll teach the captain." Mo Qinghan said, our captain Liu Qi is still sleeping at this time, in a state of insomnia.

Liu Qi was woken up 2 minutes after receiving the enemy, and the first thing he said when he woke up was, "What did you have for breakfast today?" ”

"The Underworld race has called, Captain!" Mo Qinghan said helplessly.

"Huh? The other side is sending the economy again? Liu Qi still didn't care.

"Warning! A new unit appeared in the place, presumably a new race encountered by the reconnaissance force 2 days ago-the Beetle" Mo Qiang's tone was also helpless.

"What, new units?" Liu Qi was still at a loss.

"You really haven't read the battle log?" Mo Qinghan helped his forehead.

"Oh! What do you mean by the cockroaches? Liu Qi asked.

"Yes!" *2

"Simple, infrasonic can't die?" Liu Qi asked.

The fact is that infrasound is completely incapable of harming beetles, which have a good sound-insulating effect on the carapaces of underground creatures.

"Then let the "Yinglong I. type" go. Liu Qi said that Liu Qi, who was located in the sky, did not panic at all, no matter how thick the nail was, it was useless to have short legs.

This time, the lineup is basically the same, with the beetle in the front, the beetle in the middle, and the stinging snake in the end.

This time, there were casualties on Liu Qi's side, and they were real casualties, not other unlucky children.

The strong acid spit out by the beetle is extremely corrosive, and the armor of the soldiers on the city wall is corroded as soon as they are accidentally sprayed, and then the acid enters the interior, and the fate of the soldiers can be imagined.

20 warplanes took off quickly, it can be said that the clone soldiers are indeed the king of special forces, the sky plane is on foot, the land chariot swims in the water, the spaceship sea aircraft carrier, there is nothing they will not, and almost absolutely loyal!

Soon, the whistling of fighters came, but at the same time, flying insects also came.

In an instant, the battle situation with a huge disparity in number was almost one-sided, because the flying insects dealt with the three "Silver Wing Radiance" frigates that were giant to them, and in the face of the Beetle, which had almost no anti-air ability, the "Yinglong I" was almost a harvester, and the 50mm bullet directly pierced the armor, and then the huge kinetic energy tore the whole insect to pieces.

This battle ended in the end, but the "Yinglong I" was finally shot down by 2, which was also a wake-up call for Liu Qi, and the troops on the city wall also suffered losses of different severity, the specific losses are as follows:

1. "Watcher"*3

2. "Sweeper"*1

3. "Yinglong I. type"*2

4."Silver Wing's Radiance" Shield*20%

At the same time, a very bad news also came back: the reconnaissance teams in the north and south had encountered different kinds of underground creatures, and now, there are about 7 different types of underground creatures known: beetles, stinging snakes, flying insects, beetles, underground worms, giant flying insects, and fungus blankets

Obviously, these are all named by Liu Qi, and these underground creatures do have many similarities with the Zerg of Interstellar II.

Next, the entire "Aeolus Throne" fortress is in a state of readiness, and a large number of automatic reaction turrets have been built on all 4 sides, because the number of air troops of underground creatures is too large, conservatively estimated at more than 10,000, and the same way, the new building research institute has also been unlocked and built, and now the "fungus blanket" is being cracked and studied, according to the previous encounters of the troops, the underground creatures will have a speed and recovery bonus on the fungus carpet, which is undoubtedly very unfavorable to Liu Qi's side.

"What should I do, what should I do?" Liu Qi really panicked at this time, because the number of underground creatures he faced was too huge, "That's it, the boat will sink naturally when it reaches the bridge, let it be." ”

2 Days and nights have passed, and there are nearly tens of billions of underground creatures entrenched around the fortress, and Liu Qi is only a hundred vehicles and a hundred automatic turrets, and the gap is really too big.

The calendar draw is here again.

"Please, it must be shipped!" Liu Qi pinned his last hope on the lottery.

"Start drawing." The system's voice was as cold as ever.

"Congratulations on acquiring: Radiation-free Tactical Neutron Bomb Crafting Blueprint *1"

"Wow!" This is considered hi, no radiation neutron bomb, isn't it a powerful weapon that Liu Qi longs for? No radiation, which means that there is no contamination after use, but it is not without radiation damage, but it is only for a short time.

It was immediately put into production, and the research and development of "Yinglong Type II" has also begun, and the research on the bacterial blanket was completed 10 hours ago, and the inhibitor agent is almost completed.
