The Fifth Force was very efficient, and after reaching an alliance agreement with the Dragon's Tooth Squad, they set out on their way back early the next morning with the two Doom Ones provided by the Dragon's Tooth Squad. The Dragon's Tooth Squad is also preparing to immediately turn the scientific and technological information provided by the Fifth Unit into physical objects, build several new arsenals, and begin to produce equipment such as battle mechs and magnetron tracking mines that can improve the combat effectiveness of the Dragon's Tooth Squad as quickly as possible.

In this way, after five busy days, Yuhuang finally woke up in the laboratory. After waking up, it began to blink and regain its blue eagle eyes, looking everywhere for traces of Zhou Yulong. In its brief lucidity, it remembered distinctly that it was its master who had saved it from the darkness of chaos. Now that it had woken up, of course anxious to see its long-separated owner.

"Huh, old man, woke up?"

Looking at Yu Huang, who occupied almost half of the laboratory, Zhou Yulong smiled slightly, waved his hand and said, "Long time no see, do you miss me?" ”

"Chirp!"

Hearing Zhou Yulong's voice, Yuhuang immediately turned his head to the door of the laboratory, and then screamed excitedly, waving his wings and preparing to fly towards Zhou Yulong. But it was so big that it destroyed half of the lab with a flick of its wings. Seeing this scene, the doctor who was observing the data of Yu Huang's body on the side immediately went crazy and yelled: "Brother Long, take care of your pet, don't let him destroy my laboratory!" ”

"Chirp!"

Hearing the doctor's words, Yu Huang immediately knew that he had made a mistake, so he chirped softly, tightened his wings, and began to move closer to Zhou Yulong step by step like a chicken. Looking at the huge Feather Emperor, Zhou Yulong walked over and touched its head, and said with emotion: "Old man, you can grow up so fast." I thought you could have stood on my shoulder, but now I'm afraid I'll stand on your shoulder. ”

Due to the * of the three series of energy, the body of the Feather Emperor has become incomparably huge. Now even if it tightens its wings, it is almost as tall as a laboratory when it stands, and it is impossible for him to stand on Zhou Yulong's shoulders like he once did.

"Chirp!"

Hearing Zhou Yulong's words, Yuhuang chirped softly, and rubbed Zhou Yulong's body with his huge head, it seems that he also misses the original days very much.

"Okay, it's a big benefit, I can ride you into the sky in the future." Looking at the slightly lost appearance of the Yu Emperor, Zhou Yulong smiled slightly, touched its head and comforted: "You should be happy, now you are much stronger than before, and you are already a real king of the sky." In the future, the master still needs your help, and the stronger you are, the more help you will have for me. Come, I'll take you out and loosen your muscles. Then he led the feather emperor out of the messy laboratory and into the wide open space at the entrance of the research institute.

"Chirp!"

Seeing the light of day, the Feather Emperor screamed excitedly, then spread his huge wings and flapped a few times. Suddenly, several strong winds rose out of thin air, blowing in all directions as the feather emperor spread his wings, causing the sentinels of those research institutes to retreat one after another, unsteady on their feet.

"Haha, old guy is suffocated, right? I know you're excited, come, fly with me! ”

Looking at the Feather Emperor who fluttered his wings and screamed continuously, Zhou Yulong let out a long laugh and jumped on the back of the Feather Emperor. After hearing Zhou Yulong's words, Yuhuang also flapped his wings vigorously, jumped into the air, and flew towards the sky quickly. Just like the scene when they flew for the first time.

In the next few days, Zhou Yulong was walked by birds in addition to walking birds. After that, he may take the time to practice the homology technique to strengthen his mimic ability that mutates after being radiated. Or enter the Inheritance Illusion and experiment with the final weapon. In short, time passed so steadily and peacefully. It wasn't until the morning of the seventh day that Lan Shark left the Dragon's Tooth Squad that he returned to the Dragon's Tooth Squadron. Only this time, what he was following behind was no longer Shadow and Tang Huang, but a large number of military heavy transport trucks.

"Hehe, Captain Zhou, fortunately, I brought everything."

Jumping off the transport vehicle with a slight leap, Lan Shark pointed to the dozens of military heavy transport vehicles behind him and said, "Fifteen third-generation mecha and nearly 1,200 tons of various mineral metals have all arrived. When he said this, the horns of the blue shark's forehead twitched a little. In order to exchange for two Doom One, which has a huge effect on the defense of the base, the fifth unit can be said to have made a bloody investment this time. The nearly 1,200 tons of rare minerals and metals transported this time were the result of decades of storage by their Fifth Unit, and just this time, all of them were emptied by the Dragon's Tooth Squad.

"Hehe, it's finally delivered, I'm still worried about some accidents on the way." Looking at the dozens of huge trucks, Zhou Yulong's eyes lit up and said, "By the way, where are those battle mechs and auxiliary mechas, can you show them now." "Every otaku has a dream about mecha in his heart, and since he watched cartoons such as Gundam and Dragon Fighter as a child, Zhou Yulong has always fantasized about being able to have a mecha of his own. And today, this seemingly impossible dream is finally about to come true.

"Of course, these fifteen mecha are now your ministry's, and it's no problem to deal with them." Lan Shark nodded, then picked up the walkie-talkie on his waist and called: "Attention mecha pilot, immediately activate Eagle 1 and Blue Sky 1, and demonstrate the combat effectiveness of the mecha to Captain Zhou of the Dragon Tooth Squad." ”

"Yes!"

With a serious response. The trunks of two heavy transporters in the distance suddenly and slowly opened. Then two mechas, one black and one blue, appeared in everyone's eyes. Then the two sturdy figures jumped into the mecha and began to manipulate the mecha to slowly stand up.

Unlike the bipedal humanoid mecha that Zhou Yulong expected, the mecha developed by Unit 5 was a four-legged mecha like a crab. The four feet about three meters long on the front, back, left and right support the mecha with a total length of nearly five meters, and the arthropod-like segmented structure is enough to provide the mecha with strong earthquake resistance and flexible disguised movement ability. I saw that under the operation of the mecha pilot, the two mecha moved quickly and approached in the direction of Zhou Yulong.

The construction of the two mechs is almost identical, with the upper body of the black battle mech being shot with a flat body similar to a crab. Four huge steel pincers provide the battle mech with all-round melee combat capabilities, while the barrel and missile launcher placed in the center of the giant pincers ensure the battle mech's long-range combat capability. In the shell part of the crab, the cockpit is protected by a super-strong alloy. With the pilot's operation, the upper body of the battle mech suddenly turned in a half circle. Then, with a soft sound, the back half of the crab's dorsal armor suddenly opened, and dozens of red missile warheads protruded from it. As soon as the pilot presses the launch button, these powerful warheads will be fired at the target in unison.

The auxiliary mecha is slightly different from the battle mech, and the arms on its body are not pincers similar to crabs, but long claws similar to spiders. Eight long claws are enough to reach the ground, and the four long legs are fast moving. At the end of the long claw, there are various repair tools. And among the flat shells of the auxiliary mechas, there are also a large number of repair materials stored. If there is a problem with the Combat Mech, the Auxiliary Mech can be repaired immediately. However, the combat effectiveness of the auxiliary mecha is not bad, and the ends of the eight long claws are also equipped with various long-range attack weapons in addition to repair tools. Once you fire with all your might, you can also instantly form a powerful firepower network to suppress the enemy.

"Whew, what a powerful mecha!" Looking at the flat ground that had become charred black under the demonstration of the two mechas, Zhou Yulong said in a slightly shocked manner: "This mecha is so flexible, the steering is so fast, I can't see the dullness of the machine at all." ”

"Of course, the third-generation mecha with a double waist hip joint design has a waist similar to the rotating structure of a tank turret, which can face the direction of attack faster. Moreover, this kind of mecha uses the lower limbs as the plug-in base, and the mechanical legs are used as the anti-shock system, which ensures the adaptability of the mecha to various environmental battles. After nodding proudly, Lan Shark said in a tone of obvious envy: "And each part of the mecha can also be loaded with different external weapons, if you load the Doom One on the battle mech." Then the combat effectiveness of this mecha is only afraid that it will instantly increase by N grades! ”

"Hehe, Doom One has a lot of energy requirements. Even if you succeed in loading Doom One on the battle mech, you will only have one chance to attack. After an attack, the mech's energy will be depleted. Hearing Lan Shark's words, Zhou Yulong was embarrassed to be modest. It's just that when he said this, the corners of his mouth were about to open. Anyone could tell that he was now suppressing the ecstasy in his heart.

Just kidding, even one battle mech has only one chance to launch Doom One is an extremely terrifying thing. With its flexible combat mode and structural design that can adapt to various combat environments, once this kind of combat mecha appears as a formation, what enemy can withstand the salvo of the laser cannon of the Zhou Yulong mecha army!
