Even if the decomposition was very fast, less than a second, it took Zhang Chen a full twenty minutes to decompose directly below the first target location.

The houses marked on the map all have numbers, and Zhang Chen also gave a number plate underground to determine the corresponding location.

He began to break down the past upwards.

Since the location of the septic tank was confirmed in advance, there was no awkward situation.

Soon, it was broken down to the ground floor floor.

Zhang Chen came out of the floor on the first floor, and through ultrasonic detection, he determined that the house was still safe.

Zhang Chen flew back to the underground passage and humped Zhang Yuxi up.

The two found the warehouse of the house, and Zhang Chen took out a large amount of food and water from the printer storage space. Stacked inside, so that if any of the three of them took refuge here, they would be able to survive for a few months.

"This place will be one of our secret bases from now on." Zhang Chen said, "If the food is kept in the warehouse, once someone flees here, it can survive for several months." ”

"In the future, if we hire a few more Adeptus bodyguards, maybe we can form an army and disperse our forces in these secret bases."

Owning a secret base was one of Zhang Chen's dreams when he was a child, but when he grew up, he found that it was still his dream.

One day, when the enemy infiltrates the tunnel, maybe you can still fight the tunnel war?

Looking at the map again, Zhang Chen confirmed a few houses that were relatively close to the map, and opened the passage to enter it at close range.

In one night, Zhang Chen opened up three large branches, occupying a total of one-third of the map.

He was a little tired, so he lay down on the bed at one of the secret bases, closed his eyes and rested for a while.

"Brother, are you going to sleep at the secret base?" Zhang Yuxi said, "Then I went back to sleep at home?" ”

"Hmm." Zhang Chen was so sleepy that he fell asleep after a while.

And Zhang Yuxi turned back through the underground passage.

Walking in the underpass, walking directly in a straight line without any obstacles, less than a kilometer away, it was quickly home.

Zhang Chen slept until dawn, and when he woke up, the sun outside the window had already sunburned his buttocks.

Zhang Chen quickly got up from the bed and looked at the time, eight o'clock in the evening.

Recently, Zhang Chen has always gotten up late, and he is about to form a habit, this bad habit is not good.

Zhang Chen took into account that it was because of the blood lineage.

Although his bloodline is not pure, it can be regarded as a border with the bloodline.

There are other reasons, such as the recent daily special training, which leads to physical fatigue, which is also one of the reasons why he wakes up late.

Zhang Chen stretched his waist, and today will be regarded as a holiday, continue to build his underground passage, and stop training.

He had a little breakfast and went on to break down the underpass.

It took a morning to open up all the houses in the semi-circular area with a radius of one kilometer.

With this experience, Zhang Chen felt that he would complete the other half of the work task much faster.

"It's just that I have to confirm the location of the septic tanks in those houses first, so as not to have an oolong at that time."

Zhang Chen flew out at noon.

Although he generally does not go out during the day, to avoid his presence to attract the attention of others.

But there may not be much time left for Zhang Chen, and the Hangcheng Jindan Cultivator Alliance doesn't know when it will appear, so he needs to hurry.

Fortunately, the mobile phone map has been marked, otherwise it is difficult to confirm whether the house is inhabited in the first time in broad daylight. It can only be seen at a glance when the lights are lit up at night.

According to the marks on the map, Zhang Chen began to enter the empty houses and determined the location of the septic tanks in the houses with septic tanks.

In less than an hour, Zhang Chen determined all the houses in the mark, and the situation inside.

After flying home again, Zhang Chen began to continue to break down the tunnel.

It was not until the evening that all the tunnels were opened.

Immediately afterwards, Zhang Chen printed out some reinforcement devices through the decomposed materials to prevent the passage from collapsing, and installed a protective door at the entrance of the passage, and installed a device on the protective door to hide the existence of the passage.

As long as the mobile phone sends a command, the underground passage can be opened.

Zhang Chen also marked the underground road map and sent it to Xu Xuan and Zhang Yuxi respectively.

……

At noon, the sun was intense.

Zhang Chen was sleeping on the bed.

Suddenly, there was a shout from the sky.

"Zhang Chen, hand over the Heavens Printer, and my Hangcheng Jindan Cultivator Alliance can make an exception to accept you!"

The voice was mighty, as if it was enveloped by true qi.

It seemed to sound directly in Zhang Chen's ears.

"Hangcheng Jindan Cultivator Alliance! Here it is! Zhang Chen immediately woke up from his sleep and looked out the window.

I saw several figures outside the window, floating in the air, all of them flying with Edgeworth.

A cultivator can kill people thousands of miles away with a flying sword, and besides, there are so many people who come, Zhang Chen has no confidence to defeat it at all.

Immediately jumped out of bed.

After coming to the living room, Zhang Yuxi and Xu Xuan were already here.

"There are a total of ten Jindan monks outside, I didn't expect so many to come at once, if it was just one or two, there would be a chance to deal with it, but now in this situation, I can only use the underground passage."

The three of them came to the training room.

Zhang Chen gave instructions through his mobile phone, and the movable door on the floor opened, revealing a staircase leading to an underground passage.

After the three entered, Zhang Chen entered the command again, and the passage valve closed.

It's so tight that you can't see it at all, there's a passage underneath it.

After some time, Zhang Chen and Zhang Yuxi appeared in a house closest to their home.

From the balcony here, you can see the situation of the home.

I saw that the ten Jindan monks seemed to be impatient to wait, and floated down into the courtyard.

"Roar! ～”

The three-headed dog roared as soon as it spotted its target.

In an instant, he rushed towards the ten Jindan cultivators, opened his bloody mouth, and tore through it.

The Jindan cultivators had already spotted the three-headed dog in the courtyard when they were in the sky, but they didn't notice it too much, and only thought it was a relatively large mutant dog.

But the moment the three-headed dog attacked, these Jindan monks realized that the monster in front of them was not so simple.

With one bite, the flying sword of one of the Jindan monks shattered in an instant!

Although it is not a flying sword with a lot of special materials, it can be said that it is also a human-level immortal sword specially created by cultivators.

is still bitten by a bite, this bite force and this mouthful of teeth, terrifying!

Syllable!

The Jindan monk's flying sword was bitten and crushed, and the next moment, he was slapped by the three-headed dog, vomiting blood and flying out.

"This animal is not simple, it can't be simply treated as a mutant dog, it should be treated as a demon beast!" The Jindan monks shook their hearts.

Zhang Chen, who was observing the situation from a distance, had a certain understanding of the strength of the Jindan cultivators, and without using spells, the strength was no different from that of ordinary abilities, and it might even be worse.

Under the sudden sneak attack of the three-headed dog, he actually seriously injured a Jindan monk.
