Technological Empire of the City

By mobilizing the magnetic field power in the body, Zhang Yu's body disappeared among all the people. When the old people who developed the hidden body method saw Zhang Yu disappear, they immediately showed an ecstatic expression, and their research results were completed.

"We succeeded~". The handsome old man, Shan Lao, said with a red face.

"No, I have to try it. According to common sense, it is impossible to be discovered by the eyes and spiritual sense after being invisible. Let's give it a try." Old Man Bu said after reminding.

"Yes, then try it." The old men agreed and began to detect stealth.

All kinds of instruments were brought over by the excited old men, and they performed a violent operation in the laboratory. When the test results came out and the invisibility method really came to fruition, the old men showed their yellowed teeth and cheered.

"It appears to be a success." Zhang Yu, who was in stealth, revealed his figure and smiled.

"As promised, we succeeded." The old men shouted with joy.

"The next research will be handed over to you, and I will leave first if I have something else to do." Zhang Yu said goodbye to the masters. Although they used to be liars, but now, they have helped a lot. The light of wisdom flashed from the collision of wisdom really shocked Zhang Yu,

You must know that it is extremely difficult in the world of cultivation to develop a cultivation technique from scratch, but these old men developed it in just one week. The old men were in awe.

In the villa, Tang Yan and others were very happy when they got the news that the concealment technique was successful, and couldn't wait to ask: "Brother Yu, be careful when you sneak in. If you can't, don't force yourself, you must run quickly."

"Yeah, don't be trapped." Su Mei and the other women reminded.

"I will, then, I'll do it." Zhang Yu replied and disappeared into the small world inside his body.

"must be careful". Tang Yan and other daughters and family and friends all became uneasy and risked to sneak into the true four-dimensional world, but it was a very risky thing. If it was unsuccessful, there would be no second chance.

At the seaside of the sea of ​​​​dead spirits in hell, Zhang Yu opened his eyes and stood up and found that his body was numb. After all, after sitting for a full week, it was a strange thing not to be numb. He shook his legs to make the blood flow a little, sore and numb. The feeling dissipates.

"Got to go". Zhang Yu gave himself a sigh of relief and moved in the direction he came from,

Returning to the passageway of the time and space transfer station, Zhang Yu took a deep breath, then activated the concealment technique to make himself disappear, and then slowly approached the passage. Once he entered the passage, nothing happened, just when Zhang Yu was relieved. , saw the guarding dragons at the exit.

Zhang Yu, who was almost scared to show up, stabilized his heart and walked out of the aisle on tiptoe.

The guarding Dragon Clan Jia didn't notice Zhang Yu's existence at all, and said angrily: "Why let us guard the exit, such a boring job is too embarrassing for me, it is my job to fight for the Dragon Clan. it is good".

"Don't complain, just accept your fate, who made us the strongest group in the dragon army, and the weaker dragon family can't beat that human at all." Long Clan Yi advised.

"Yes, being strong is also a trouble, hey~".

In the conversation between the two dragons, the invisible Zhang Yu had already gone away and disappeared in the time and space transfer station, but the dragon guards knew nothing and were still dutifully guarding the exit, thinking that Zhang Yu was still in **** in.

Going deep into the time and space transfer station, Zhang Yu found that some dragon figures flew in the sky from time to time. He didn't dare to relax easily, and he didn't show up. He maintained his concealment method, and the strange magnetic field merged with the surrounding, making Zhang Yu like a non-existent person. people.

"The first pass is passed, and there is a second pass." Zhang Yu muttered to himself, looking at the transfer station passage in the distance.

The passage is inside the real four-dimensional world. There are dragons on both sides of the passage. Zhang Yu is calm, and starts to slowly approach the passage. Just in case something will make a sound, Zhang Yu first observed the ground and found the most Fits the foot.

No sound came out. Zhang Yu was only ten meters away from the entrance of the four-dimensional world, but when he got closer, he found that two dragon guards, the huge dragon body was blocked at the entrance, and it was difficult to enter. .

"Damn, to block the passage with your body, is it too much?" Zhang Yu cursed in his heart.

But there is no way. It seems difficult to do it without disturbing the dragons to enter the passage. After all, the concealment method is only invisible, and it is only invisible. If it is touched, it will still be discovered. After all, it is not completely disappeared.

"It seems to divert the dragon guards away." Zhang Yu groaned and left the passage.

Behind a small mountain wave nearby, Zhang Yu took out a small time bomb, and some of the explosives in the bomb were removed. Otherwise, if the explosion was too violent, it would blow up the small mountain wave and cause chaos in the dragon race. .

The power of the explosion is smaller, and a small movement is formed, which will make the dragon clan suspicious and come to check, without disturbing more dragon clan, so that there is a chance to approach the entrance of the passage and enter it.

"Just do it." Zhang Yu secretly said and started to act.

The time bomb was installed behind Xiao Shanbo, where the dragon guards could not see it, and then Zhang Yu sneaked back near the entrance of the passage, only to wait for the dragon guard to leave and immediately enter the passage, and the plan began.

"Beep beep".

The countdown to the time bomb has begun, and when the reading reaches zero, the bomb is detonated.

"Boom~".

As soon as a muffled sound appeared, it alerted the two dragon clan guards. The stunned dragon clan stood up fiercely, and the huge dragon eye looked at Xiao Shanbo and said in disbelief, "Could it be that human being came over?"

"Whether it is or not, you will find out by looking at it in the past." Ryuzucho suggested with a serious face.

"it is good". Longzu Bing nodded, leaped to the low altitude without making a sound, approached Xiaoshanbo, and stared at the back of Xiaoshanbo, only to see a small pit on the ground, nothing else.

"Strange, nothing." The dragon clan said in surprise.

"It's good, how can there be a small pit here?" Ryuzucho said with a confused expression.

As the arrogant dragon family, they have never seen such things as technology. Of course, it is impossible to know what is a time bomb, and they can't see the wreckage of the bomb. They are foggy and underwater, so they have to return to the channel to continue to care.

At this time, Zhang Yu had already entered the passageway within the short time when the dragon guards left. The huge energy in the true four-dimensional world continuously infiltrated, causing Zhang Yu's body to evolve rapidly.

That kind of evolution made Zhang Yu unable to feel comfortable. If he hadn't wanted to hide it well, he would have wanted to cry out happily.

"It's really pure energy. I don't know how huge the energy in the real four-dimensional world will be. It seems that you can see it soon." Zhang Yu secretly looked forward to it.

Slowly approaching the exit, a huge snoring sound penetrated into his ears. The confused Zhang Yu found that the dragon at the exit also blocked the exit with a dragon body. If he wanted to go out, he had to wait for the dragon guard to move away. .

But how is this possible, if he is discovered by the dragon clan, Zhang Yu is sure that there will be a swarm of dragon army coming soon.

"Damn, why do you like to block the entrance and exit with your body? What the **** is wrong with this?" Zhang Yu secretly said annoyed.

There was no way, Zhang Yu could only wait in the passage, waiting for the dragon guard to wake up and move the dragon body away by himself, but Zhang Yu soon discovered that he thought too much, and the dragon's sleep time was simply amazing.

It has been three days and three nights, and there is no sign of the dragon guards waking up at all. If this continues, I don't know when it will be delayed, and the longer I stay in the passage, the more likely accidents and dangers will occur.

"I can't wait any longer, but how can I divert the dragon in front of me?" Zhang Yu frowned secretly.

If you can't get out, you can't make a move outside to divert the dragon clan, and make a move in the passage, that's even more impossible. If dragons come in at the front and rear entrances and exits of the dragon clan, it's not being surrounded. .

"Can I just force it through?" Thinking to the end, Zhang Yu found that he had only one way to go.

Creeply approaching the sleeping dragon, Zhang Yu put his hands on the dragon scale slowly. Now that he has made a choice, Zhang Yu will not be half-hearted and focus on launching the strongest chain of seals. Seal the sleeping dragon.

The next second after the seal, the familiar dragons woke up, and the moment they were frightened and wanted to shout, they were taken into the small universe by Zhang Yu, the exit was opened, and bright rays of light were reflected in front of them.

"Freedom is at hand". Zhang Yu secretly said in ecstasy.

In the small universe within the body, the sealed dragon clan exclaimed, "Help me, where is this place?"

When Zhang Yu stepped out of the true four-dimensional world, he completely felt how dazzling the world without repression was. The shock of energy surged in the body, which was quickly absorbed by the body of the Protoss, making Zhang Yu as if he had been hit with hormones. excited.

"Enemy Attack". A roar spread throughout the entire dragon clan.

The stunned Zhang Yu didn't know how he was discovered, until he saw another dragon beside him, roaring hoarsely, and then he understood that there were not only one dragon guarding, but two, and if one dragon disappeared, it would definitely be was discovered.

"It's too late, you have to run away." Zhang Yu secretly said anxiously, and fled frantically, but did not release his stealth when escaping.

"Hey~".

"Hey~".

"---".

The members of the dragon clan who burst into the air shouted and asked.

"what happened".

"There's another guard."

"Where is the enemy".

"---".

The dragon guard exclaimed, "In the blink of an eye, Long Hao disappeared."

"What, look for it, there must be an invisible enemy coming." As soon as the words fell, an experienced dragon guessed Zhang Yu's ability, which made Zhang Yu's face change dramatically. ..
