"Yes! Carl got up and spun around, he couldn't make such a powerful design, he could only admire it.

When he saw a pipe running from top to bottom to a bucket and finally to a sink, he asked, "Brother Robin, what does this do?"

"Well, it's for collecting fresh water, there's a pipe leading to the top of the tower, there's a rainwater collector on it, you can collect rainwater and dew, and then filter it through this bucket, and you can get to this tank, and it becomes fresh water that we can drink. ”

Robin showed them in turn, and it was a work that he was very satisfied with.

"You don't need magic, that's amazing...... So what if it doesn't rain? How can you get enough dew?"

Wizard Keith, like Cher, admires Robin's way of going about his daily life without magic, and for him, magic is already an indispensable tool in life.

"If the number of people is small, the rainwater and dew collected will be enough to sustain it. Robin said as he walked over to the sink, where there was a round lid in the corner.

Robin pointed to the lid and said, "Here is a well I dug straight to the underground water source, even if it doesn't rain, I am not afraid, and I can live on this well water." ”

The more Robin spoke, the more interested he became, and it was a great pleasure that his work could be shared with others.

He pointed to another water conveyance equipment and said, "This is to transport wastewater, and the used water can not only be used to water Apalo or other crops, but also to clean it, and the exhaust air that we breathe and exhaust can also be absorbed and converted into fresh air, how about it? ”

Karl touched the stubble on his chin and exclaimed, "It's amazing! You have no shortage of food and water here, you are completely self-sufficient, and even the waste that is used or excreted can be used reasonably, you are not an underground shelter at all, this is completely the most perfect place to live!"

Keith nodded and said, "Well, yes, that's amazing! No one would have thought that there would be a hole under this abandoned clock tower." ”

And the little girl Cher, looking at Robin, her eyes are even more full of respect and admiration.

Just as they were chatting and chatting, there was a sudden rush of noise in the shelter, like the sound of a whistle, and Carl and the three of them looked around in surprise and asked Robin what was wrong.

Robin smiled, but unhurriedly finished the last bite of the fruit slice, then patted off the crumbs in his hand, and said slowly: "Okay, lunch time is over, it's time for us to welcome the guests!"

"Guest?!" Karl asked with a frown, "Is it the Wild Sword Mercenary Regiment?"

Robin nodded and beckoned to them, saying, "Come with me and let you see a good show." ”

Robin led the three of them to a secret room, where there was a rectangular desk three meters long and one meter wide, on which were lined with two layers of labyrinthine miniatures made of unknown materials.

Cher in the most advanced room exclaimed loudly when she saw this model, "......Ah? A diorama of the entire Del Street, above-ground streets and underpasses?"

Robin smiled and nodded, he said, "It's a magical device, every time I set a trap, I'll associate it here, and as long as the trap is triggered, it will be displayed here." ”

"And I've set up snooping scopes and control mechanisms at the corners of some of the traps and passages, so we can monitor and operate them without leaving our homes. ”

"Now, it has connected all the traps and traps of the whole Del Street, so to speak, the whole of Del Street is under my control. Robin explained to them as he pressed the switch buttons.

Under Robin's operation, the three of Karl were completely stunned, they couldn't imagine that the entire underground of Del Street was actually connected, and as long as Robin pushed a button, these passages could change direction at will.

They couldn't believe that this underground labyrinth full of traps could really be made by him as a human, and if all of this was true, as Robin said, then Robin was the underground master of Del Street, and he could resist the thousands of troops on his own......

Imagination doesn't have to be taken seriously, but the reality is really happening in front of their eyes, and in the surprised expressions of the three of them, they see the elite team of dozens of members of the Crazy Sword Mercenary Regiment being devastated in the underground passage.

Initially, they see that Robin is just using some simple traps that are harmless to warn the other party, trying to make the other party retreat. However, when the warning failed, Robin began to attack in earnest.

It wasn't until this time that the three of them really saw how terrifying Robin's trap traps were.

Not to mention those ordinary traps such as knives, forks, swords, and halberds, falling rocks, spears, etc., when they saw that Manmos suddenly couldn't control his madness and wiped out his entire team with his own hands, they all opened their mouths in surprise, and their eyes were as wide as two walnuts!

Under Robin's explanation, they finally realized that the lamp oil was actually made from two hallucinogenic plants, mandala flowers and psychedelic sage, which can make people hallucinate!

By using traps, you can create illusion effects, which are terrifying!

And when they saw O'Neim's team wiped out in the water prison and the fire prison trap one after another, they realized even more what it means to be horrible, the terrible feeling of being trapped under the water and suffocating, and the painful feeling of being sprayed with fire oil and burning their bodies, which is completely a double destruction of the enemy's mind and body!

Anyone who has experienced this blow again and again, even if they are lucky enough to escape, will inevitably be squeezed out of fighting spirit and fall into the abyss of despair!

How fortunate the three of Carl were at this time, they were glad that they were not Robin's enemies, if they hadn't seen it with their own eyes, they wouldn't have believed the true meaning of being a husband and a man.

But today, with their own eyes, they witnessed the annihilation of the Crazy Sword Mercenary Regiment, and they saw that in the end, only the deputy leader of the Crazy Sword Mercenary Regiment was left alone, and he was still ragged and gray and had to escape from the exit of the passage.

At the same time, they saw in O'Neum's desperate expression that Oonem, after losing his brother and losing his army, finally returned to the same starting point from the entrance of the passage he first entered!

And O'Neum, after he turned around a lot, he didn't even see the shadows of Robin and the others, which is simply a kind of irony.

When they saw O'Neim crying out in despair and roaring miserably into the sky, several people sympathized for him for no reason in their hearts, and they secretly muttered that from now on, they must not be enemies with Robin, absolutely not!
