Technological Empire of the City

Zhang Yu, who didn't realize that he was careless, was working with Shi Xi and other students to manufacture a large number of particle gun weapons, particle gun weapons, and arming the bone gold robots. The laboratory was busy.

Just when Zhang Yu wanted to develop more kinds of weapons, Guangnao Xiaowen sounded the alarm: "Brother Yu is not good, the spy satellite found that the four dragons in the Moon Continent flew directly to the Xingyue Country. Come on, you seem to know our location."

"How is it possible, how do they know". Without waiting for Zhang Yu to ask, Shi Xi was shocked.

"Yes, the blood of the red dragon and the white dragon has been sealed by you, teacher, how did they find our Xingyue Kingdom?" Xu Bo and others also panicked and said that when it was time to fight the Dragon Clan, they couldn't stop panicking in their hearts. After all, the Dragon Clan was so powerful that the new robot had never experienced actual combat, so they didn't know if it could stop the Dragon Clan.

"Now it's not about how the dragons know the location of our Xingyue Kingdom, but to prepare for battle." Shu Qiaoqiao reminded nervously.

"Qiaoqiao is right, since you can't hide, let's fight." Zhang Yu said solemnly, and immediately ordered: "All Bone Gold robots are on standby at any time, and Xingyue Kingdom enters a state of first-level alert. Let the citizens hide in the underground base first."

"But the underground base in the capital has been destroyed and has not been rebuilt." Guangnao Xiaowen reminded.

"Then use all transportable equipment to transport citizens to underground bases in other cities to hide. We must ensure everyone's safety." Zhang Yu thought for a moment and then ordered.

"Yes". Guangnao Xiaowen responded.

The order was issued, and all the citizens in the capital of Xingyue Kingdom had to leave their homes for refuge again. In Villa No. 1, Zhang Yu's parents and children's expressions changed greatly, and the first-level warning signal had already sounded.

The eldest daughter Zhang Yue said with a sad face: "Come again".

This month, this is the second time I have entered the refuge base. The first time was a red dragon. This time it will not be a dragon again. Thinking of this, Zhang Yue felt that there was no need to play in the future. After all, the number of dragons But a lot.

"Don't talk nonsense, just leave with the children." Zhang Qiang, the grandfather, shouted eagerly.

"right". Zhao Yan, who woke up, said in a trance.

Yan Xi, who came from hell, and Zhang Meng, who had just woken up, as well as the nanny and others, picked up Zhang Yu's children and fled the capital city of Xingyue Kingdom. Migration begins.

"Get in the car."

"Line up".

"Hurry up, time is running out".

"---".

Amid the noise, the number of citizens in the capital was rapidly decreasing. At this time, all the high-level officials of Xingyue Kingdom gathered in the conference room of the headquarters, and they also learned that the Dragon Clan had discovered the location of Xingyue Kingdom.

"Di~".

With a light sound, Zhang Yu's figure was projected in front of everyone, and he opened his mouth and said, "You all go to refuge, just leave it to me here."

"Then be careful." With Zhang Yu as the mastermind, Tang Yan and the other women were very relieved and ordered.

In the laboratory, Shi Xi and others who had packed their luggage were also chased away by Zhang Yu, and only Zhang Yu and Nie Long Xiao Hei were left. Fighting is not an easy task, Xingyue Kingdom is now No one can help, their strength is too weak.

"Are you ready?" Zhang Yu looked at Nielong Xiaohei and asked.

"anytime". Nie Long Xiao Hei replied with a serious face.

"Very well, let's go, let's go outside and wait for them". Zhang Yu signaled that the evil dragon Xiaohei followed Zhang Yu and came to the empty and flat ground outside the laboratory. With the flying speed of the dragon race, they would come soon. If the bone gold robot could not stop him, Zhang Yu would Yu and Xiao Hei became the last line of defense of Xingyue Kingdom.

The very nervous evil dragon Xiaohei asked: "Master, why should I offend the dragon clan for some half-dragon people, I really can't figure it out."

"I don't know either, I just thought I should save people, so I saved them." Zhang Yu smiled and said.

"It's really messed up." The evil dragon Xiaohei who heard the words was speechless.

In the ecological warehouse of the headquarters laboratory, the imprisoned red dragon and white dragon waited patiently. Killed, the two of them will be too excited.

"Human, it's too late to regret, accept the punishment of the dragon." The hateful red dragon laughed sinisterly.

"It's a pity that I couldn't kill the human who imprisoned us by myself." The white dragon, who found that he was about to be free, blushed brightly.

Outside the sky, in the vast space, the Bone Gold robots gathered in the first line of defense. The arrival of the enemy had already notified the robots, and they were immediately ready to start the war mode.

"Hey~~~".

The sound of the explosion sounded, and four rays of light flew from afar. After a closer look, I found that they were four dragons, with huge bodies and brilliant colors on the dragon scales, but they were the enemies of humans.

"Beep beep". As the distance was approaching, the Bone Gold Robot moved with a "click" and issued an alarm: "The enemy is approaching, attack."

As soon as the voice fell, all the Bone Gold robots raised their wrists and held a huge gun barrel in both hands. There was a round tube behind the gun barrel, which was connected to the energy on the back of the Bone Gold robot. The accumulated energy made the muzzle dazzling. The white light shot out fiercely.

"Hey~".

"Hey~".

"---".

The four dragons that flew over didn't care. After all, they were just a little bit small. Can they still hurt the dragon clan? However, Ao Hong, the horned dragon who took the lead, didn't care. He immediately discovered the energy intensity of the attack, and his face changed in shock.

"Get out of the way."

"Ah~". Hearing the words, Sanlong's face was confused, and he didn't understand why he avoided it. It was obviously just an attack from some ants.

Unprepared, Ao Qing, Ao Yin, and Ao Lu Sanlong, who were hit by the particle cannon, were immediately blasted with a huge wound by the particle cannon, and the dragon scales turned into residues pierced into the dragon's flesh at the moment of shattering.

"Ow~". Sanlong suddenly screamed and rolled in space.

"It's all right". Seeing the **** and tragic appearance of the three dragons, Jiaolong Ao Hong said with worry.

"It hurts, what the **** is this, why is the attack so strong, is there such a thing in the world prison?" Ao Qing is a girl, looking at her wound with a bitter face, and muttering.

"Hey~".

"call out".

The particle cannon fired a salvo again, and the horned dragon Ao Hong found Ao Qing and the others in his hands. He couldn't dodge them at all.

In the midst of cursing, the Horned Dragon Ao Hong used his huge dragon body to block the attack route of the particle cannons, making targets for the three young dragons, and all the particle cannons bombarded Ao Hong's dragon body.

"Boom~".

The dense particle cannon made a burst of thunder.

Seeing this scene, Ao Qing Sanlong immediately said in shock, "Uncle Jiao, are you alright?"

"I'm fine, but the attack made me a little sore." Jiaolong Aohong said with a shocked face, you must know that it is a cultivation base in the realm of the gods. Although its strength is mostly suppressed by the world prison, its body strength has not been suppressed, and the particle cannon can make it hurt, one can imagine. How surprised the dragon was.

"What to do now, we can't get through, the signal of the blood formation is in the planet in front." Ao Qing said with a puzzled face.

"You guys wait here now, I'll get rid of those weird iron men." Jiaolong Ao said with a serious face.

"Okay". Ao Qing Sanlong responded and hid far away to avoid being hit by the aftermath of the attack.

At the same time, in the square outside the Mars headquarters, Zhang Yu and the evil dragon Xiaohei watched the pictures on the monitoring satellite and found that among the dragons that came, three dragons were similar to the red dragons, but only one dragon was very powerful. No particle cannon can break its scales.

"That should be the dragon in the immersion period." Evil Dragon Xiao Hei explained.

"Really, let's try it out first." Zhang Yu, who heard the words, suddenly said, and then ordered: "Xiaowen, let all the bone gold robots deal with the pure white horned dragon together and try all its abilities."

"OK". Guangnao Xiaowen replied.

In space, the Bone Gold Robots surrounding the solar system all flew in one direction, and that direction was the location of the ceratopsians. The Bone Gold Robots, which flew at an amazingly fast speed, were like shooting stars.

"咻~~咻~~咻~~".

More and more bone-gold robots merged with the bone-gold robots that fought against the horned dragon. The huge number made the bone-gold robots look densely packed. Ao Qing and other dragons who were hiding far away shouted in shock.

"Uncle Jiao be careful."

"fine". The Horned Dragon Ao Hong, who had found that the particle cannon attack didn't work for him, rushed towards the army of bone gold robots with a face full of indifference.

Immediately afterwards, the Bone Gold Robot fired a salvo of particle cannons, like a meteor shower, covering a large area of ​​space, causing the Horned Dragon Aohong to be hit by the particle cannon no matter which direction it flew from.

"Boom~".

"Boom~".

"---".

The intensive particle cannon attack changed the face of the Horned Dragon Ao Hong. Even if the particle cannon can't break its scales, it will still hurt, and there are too many dense particle cannons, in case it hits the eye Wait for the weak point, that's bad.

Thinking of this, Ao Hong flipped the dragon's body and let his back face the dense particle cannon attack.

"Boom~".

The last shot stopped, the particle gun barrel needed to cool down because of overheating, and the back of the Horned Dragon Aohong was already charred black.

"Hit them". Ao Qing Sanlong shouted and cheered.

"Swish".

The flying speed of the horned dragon Ao Hong was dozens of times that of the red dragons. The cruising dragon body entered the defensive position of the Bone Gold Robot at once.

"Bang~".

"Bang~".

"---".

"Huh~". After sweeping away the surrounding robots, Jiaolong Aohong found that the robot he had attacked did not flatten or fall apart, but rejoined the robot team and attacked him. ..
