As early as when Zhao Si was in charge of the intelligence department, Dad's pharmacy was one of the many suspects.

Even, before Zhao Si, the pharmacy was already on the danger list.

Daddy, such a master-level figure, does not show his eyes every day, does not chase fame or profit, and stays in this small city like an ordinary little old man, which is doubtful enough.

In this era of chasing fame and fortune, from the perspective of normal people, it is not normal to be indifferent to fame and fortune.

In the past, there were also so-called "masters", who said that they were indifferent to fame and fortune, and they were unwilling to go out of the mountain, but in fact they were just waiting for a better price.

In addition, the eldest apprentice Gu An is also one of the reasons why his father is suspected.

Mercer knew the true relationship between Gu An and his father, so as soon as he got the news, he asked Yu Tuo to lead his troops to surround the entire pharmacy.

"Lord Yutuo, we found the kind of metal mentioned by Lord Mercer below." A mechanical creature in charge of the search hurried upstairs to report to Yu Tuo.

"Well, I'll take a look." Yu Tuo responded flatly.

His main body was too large to enter the basement.

With a click, the mechanical armor on his shoulder parted to reveal a black hole, and then an oval, silver-white metal ball bounced out.

The metal ball was about the size of a bowling ball, and its surface was covered with gaps, and wisps of dark blue light loomed through the gaps.

"Click-click-"

The metal ball cracked, and mini-robotic arms appeared on the left and right, the arc-shaped carapace on the back unfolded, and the lower half of the oval split into four parts, becoming four mechanical legs.

This is also Yu Tuo's doppelganger, mainly used for reconnaissance work, flexible in action, and not weak in combat effectiveness.

He began to act, four sharp metal legs clanging on the wooden floor, and followed the ants all the way down, past the first basement, to the second basement.

The half-cut corpse of the suspected alien caught his eye first, but he also made a similar judgment as the rest of the mechanical creatures.

"Hybrids?"

Yu Tuo's eyes flickered, during his time in the underground laboratory, he had come into contact with many failed products, many of which looked similar to this corpse.

He himself was very opposed to this kind of behavior, and always felt that mixed organisms were uncontrollable and would cause trouble sooner or later, so he just glanced twice and withdrew his gaze.

"Where's the box?" He asked his subordinates.

"It's right ahead, please come with me, sir." The subordinate replied respectfully, "This underground world is very large, and that old man has opened up all the underground areas of the surrounding streets, and the area is not smaller than the underground floors of our base, I really don't know how he did it." ”

"Is there anything else you found besides that metal?"

"No ...... for the time being"

The subordinate replied like this, and then felt that it was inappropriate, after all, Yu Tuo was once a human being, so he added: "There are some very commemorative collections, all of which were before the war, and there are many valuable materials, if you are interested, we can ...... it."

"No need."

Yu Tuo's tone was indifferent, and he refused, not interested in these at all.

With his current status, the treasures in the eyes of the common people are all within his reach.

What is too easy to obtain is not precious.

And he's always only liked to pursue power.

Soon, Yu Tuo saw the potholes in the box, and after observing it carefully, he instructed his subordinates: "It's that kind of metal, bring it back to the underground base, and arrange a few more people along the way to protect it." ”

"Yes!"

"Where's Susha?"

"Over there, in the corner, a lot of people are over there." The subordinate pointed to a dark corner, "They found the entrance to the third basement floor and are still looking for the key. ”

"Take me to see it."

"Okay, please come with me."

The subordinate respectfully led the way in front, and along the way, he introduced the rest of the items found on the second basement floor.

In this dark underground area with no end in sight, the most stored potions are naturally more than enough to support several major wars.

There are also some special potion recipes, all of which have been improved by Daddy, even if they are mechanical, they need to be referenced.

The mechanical clan also got some of the wreckage of the spaceship, and naturally knew that a very glorious potion civilization was once born in the starry sky.

The path of potions is also an evolutionary path that may work.

The mechanical family itself does not need medicine, but it can learn from some development experience, learn from each other's strengths, integrate the strengths of hundreds of schools, and find its own way.

In the years since the end of the war, not only the human race has developed, but also the mechanical race, and the mechanical race, which occupies the vast majority of resources, has developed faster, which is one of the reasons why many people do not see hope.

At this time, in that dark corner, a group of mechanical creatures were watching Su Xia look for the key.

"It's not a ...... This one isn't ...... either."

Su Xia was carrying several large bunches of keys in his hand, heavy, shaking and clanging, some of the keys had paper instructions on them, and the other part had nothing on them.

Dad left in a hurry, and he didn't tell too much, most of the time he felt that there was no need to explain these trivial matters, just let Su Xia find it by himself.

I don't know how many keys I've tried, but even the mechanical creatures known for their patience get tired and finally ......

"Click-"

The lock cylinder popped out, the sound was crisp, and the passage to the third underground level was finally opened.

Su Xia collected the keys, looked focused, removed the heavy lock, and slowly lifted the heavy cover, revealing a downward pitch-black entrance.

As soon as it was opened, a rotten aura instantly surged up from the ground, as if it had been sealed in dust for thousands of years, mixed with bursts of cold air.

"Whirring ......"

The cold wind was howling below, and the space was unknown, and the wind was terrible in the dark, like the wail of a ghost, which made goosebumps rise.

More rotten breaths rushed up with the wind, gushing out.

Su Xia bore the brunt of it.

He covered his mouth and nose, frowning slightly, feeling uncomfortable.

This cold and strange aura made him seem to teleport to the world of tomb robbery notes and ghost blowing lanterns.

Behind him, a mechanical creature said suspiciously, "It's gloomy, like the entrance to a cemetery, I heard that this area used to be a mass grave, there shouldn't be anything bad down there, right?" ”

"How many times have we said that we are the products of science and technology, we are materialists!" Another mechanical creature retorted, "Even if it's a real ghost down here, we're going to beat him to admit he's not a ghost!" ”

"That makes sense, you go first!"

"No, let Su Xia go first!"

“……”

Su Xia was speechless, took a mask and put it on.

The smell of decay below is too strong, and the mask also plays a role in psychological comfort, anyway, his body is a player template, and he can't die.

He turned on his flashlight, and the blinding glare peeked into the entrance of the passage, only to see the cold stone steps down one step.

The stairs continued to spread deep underground, and at last they could not reach even the light, and were slowly swallowed up by the cold darkness.

"It's pretty deep." Su Xia thought for a moment, "Daddy alone, can he really dig out such a big underground world?" ”

He gripped his flashlight, took a few breaths of fresh air, and was ready to go down.

At this time, Yu Tuo happened to come over.

The mechanical creatures surrounding the entrance pushed out of the way one after another, making way for a way: "Lord Yu Tuo! ”

"Hmm."

Yu Tuo responded lightly, walked to the underground entrance, and took a brief look.

Then, his four mechanical calves worked hard in unison, and he jumped directly into it, and without a trace of hesitation, landed steadily on a certain step below.

"Whoever wants to come down, come down, there's no danger."

Yu Tuo did not wait for everyone, and continued to descend the stone steps after speaking, not in a hurry or slow.

Su Xia followed closely behind, holding a flashlight and walked in.

The eerie and cold breath came to his face, blowing on his skin, like a cold knife, cold to the bone.

He looked closely, and the stone steps and the stone walls on the left and right were blue-gray, and it was a very hard rock, with artificially excavated notches.

After walking down about 100 meters, the space in front of him became larger.

The stone wall on the right is still there, but the left side is empty, leaving only a large and dark underground world with no edge in sight, and the whole staircase hangs over the cold cliff wall, and there is not even a railing on the left side, so if you are not careful, you may step on the air.

"It should be the underground grotto left before, but it just happened to be discovered and used by your teacher." Yu Tuo, who was walking in front, suddenly spoke, "This area used to be rich in stone, and we also encountered a similar space when we opened up an underground base, and the organization of the Zero Point Tavern also had the same underground space. ”

"Lord Yu Tuo, in this way, there are huge cavities underneath Coral City?"

"Well, the city sits on a bubble."

After Yu Tuo finished speaking, he didn't say anything more.

And Su Xia stared around, thinking as she walked.

If a few small nuclear weapons such as the "Sound of Destruction" are detonated underground, will it cause the entire Coral City to collapse and sink directly into the ground?

Of course, this is a trick to kill a thousand enemies and lose a million, and the humans of the entire city will have to be buried together.

"Hey, this is ......"

On the wall, a trace caught Su Xia's gaze, making him withdraw from his state of thought.

It was a claw mark, three in all, of varying shades on the stone wall, like the result of some violent animal.

Keep going down and you'll find more claw marks.

In addition to the claw marks, there are other similar marks on the stone walls and steps.

With Su Xia's current strength, just get a few pieces of metal and leave marks on the wall.

"The claws of some kind of creature, very hard, comparable to metal, are they bugs?" Su Xia pondered silently, "There used to be a living bug down here?" Daddy wants to use fresh insect ingredients to make potions? Or is it ...... He's also experimenting? ”

With suspicion, Su Xia continued to descend and saw more and more traces.

Now that his ugly doppelganger is the leader of the two hives, he knows more about the structure of the various bugs.

He was almost certain of what kind of bug had left some of the traces.

"These small holes look like they're made by sharpback worms...... And this trace, it should be left by the claws of the Black Wing......"

After going deep into Mo for about 300 meters, the two finally came to the bottom.

The rest of the mechanical creatures followed, all behind, not fast, collecting information as they went.

The path at the end of the stone steps was broken, leaving only a corridor ahead, and it was still dark beyond.

Yu Tuo found a lever and pulled it hard.

"Click-"

The entire underground world lit up in an instant, and the bright lights lit up one after another at the top, and the surrounding walls also appeared with light, and the darkness nearby was banished, but the cold in the distance was still there.

There was no light in the deepest part of the underground as far as the eye could see, it was still pitch black, and the cold wind was howling, as if there was a black fog surging.

When they saw the true appearance of a part of this underground space, the mechanical creatures that were still on the stone walls were shocked, and even they felt creepy.

"How can there be so many bones? Is this really a graveyard? ”

"I tried scanning just now, but something was bothering me, and I thought there was a mess of rocks down there......"

In the area illuminated by the lights, there are large and small corpses.

The bones were stacked on top of each other, and all kinds of creatures were mixed together, and it was no longer possible to see the specific race, some of the bones looked normal, and some looked very deformed, as if they were from some kind of mutated monster.

If you are a timid person, you may faint on the spot when you see this terrifying picture.

Above the countless skeletons, there is a suspended corridor of steel joints.

Along the corridor, one can walk to the center of the bone area, where there is a large circular stone platform.

"It seems that your teacher is also conducting secret experiments, and the high platform in the center is his experimental area." Yu Tuo stepped into the suspended steel corridor, "The countless bones below here are the creatures that died in his experiments. ”

"The teacher never told us about it."

"Well, I guess I don't want to ruin his image in your hearts."

It's normal to think about it, with the personalities of Hong Bafu and Lan Bafu, if you know that Dad is secretly doing experiments below, and so many people have died, you will definitely not be able to stand it.

In their hearts, Dad is an ordinary family member who has never had blood on his hands.

Susha also walked up the suspended steel corridor.

He could tell that some of the bones below belonged to humans.

If all these humans died because of Daddy's experiments, then Daddy's previous image would have been subverted.

But he vaguely felt that things should not be so simple.

One after the other, the two walked up the circular platform along the suspended corridor.

Above this, there is a huge laboratory, similar to the underground laboratory of the mechanical family, with all kinds of experimental equipment and equipment, but with a little more simple atmosphere.

The door to the lab is open and no key is required.

A large number of paper materials, electronic materials, video files, photo records, etc., are completely stored in this laboratory, and there are even special labels and classifications, so there is no need to waste time to find them.

"Let me see ......"

Yu Tuo jumped onto a long table where the materials were stored, took out the top document and flipped through it carefully.

Su Xia also took a copy of the information to check.

He flipped through the pages and found a file of the subject, which contained the subject's personal information, with a photo attached to it, and a number attached to the video file.

[Subject: 00218]

[Survival time: 64 hours]
