It was a triangular, dark blue piece of metal, only half a finger's width apart.

This thing must have fallen from the guy who had been beaten to pieces.

Judging by the location of the tree. This shouldn't have been dropped accidentally.

Because from a normal physical point of view, what falls should fall in the direction he flew out.

But the tree was on the side of the path where the man had been smashed.

So this thing was specifically thrown by that person in the process of being knocked flying.

Fu Hao stared at this thing, dark blue prismatic metal.

If there's anything special about it, it's that it has strange symbols on it. This makes it look very much like some kind of key or a rune in some game.

He quickly put it away. Whatever it was, it was definitely something that killed the person before it. And it's going to attract a freak who will knock him out and crash through four concrete walls at once, and he won't stop.

It is even very likely that it is the reason for the sudden accident of the entire Roy family in the underground world.

No matter which one it is, Fu Hao doesn't want to waste time here.

He turned around and quickly returned to the complex. Judging by the situation in this complex, there were once two different waves of people in this building.

One of those waves should be the Roy family's people. They set up a research room, and after the accident, they took away the information.

The other wave of people is completely different. They are in this test chamber, while destroying. On the other hand, it seems to be looking for something. It looks like it's very bad.

Almost everywhere they came, things were destroyed and burned.

But no matter what, Fu Hao still has to find the information he is looking for. He looked for the marks of the fire in the central laboratory.

In fact, the rest of these laboratories. Fu Hao found more information than he wanted to find.

Clearly, these are not the goals of the saboteurs.

Fu Hao's hands and feet are fast. These materials are 200 years old. But maybe because it's a laboratory, a lot of things are well protected.

After putting away most of the materials he could find, he began to flip through the books in a clean room to find what he wanted.

The four families of that year, even in the era of harmonious relations. It's the same with ghosts.

So all four of them actually left cheat sheets on the experimental results.

And what Fu Hao finally found was some of the private information retained by three of them.

This is a big bargain for Fu Hao. These are relatively small and incomplete.

But when there are three comparisons, it is still very easy to compare the content that Fu Hao wants.

After getting the two formulas he wanted, Fu Hao quickly remembered them. Then immediately leave the built-up area.

It took him half a day. Run around in the underworld.

After getting the recipe, he needs to get at least one copy of "Lady Luck's Darling" and more than two copies of ordinary ingredients.

These things can be convenient for him to dispense medicines. For the medicine given by Patricia. Fu Hao can't believe it.

Some things are still reliable for themselves.

And from the data, Fu Hao can draw such a conclusion. Medicines, made directly from these herbs from the underworld. It is far more powerful than the second-generation or third-generation materials cultivated in the Roy family's own ordinary world.

In the afternoon of the day. It is also regarded as a painless effort. Everything seems to be going surprisingly well.

Within an hour after he came out of the research room, Fu Hao found the second "Lady Luck's Darling" flower.

The location of this flower is on a cliff to the east of the Underworld.

For Fu Hao, who can walk upright on buildings, it is not difficult to take this kind of flower at all.

He then robbed an Adventist duo and took the ordinary materials from their hands. At least two copies of the materials for ordinary "super gene drugs" were gathered.

That's it. Fu Hao has accomplished his goal of entering this world.

He was naturally relieved.

It's not early. The place where he stayed at this moment was not far from the front of the complex.

Sit down on a big tree in the grove and eat some food, then take a break and get ready to go back.

In this underground world, Fu Hao always feels a little insecure, so leave early. It's not a bad thing for yourself.

After eating. Take a break.

Somewhat bored, he took out the dark blue arrow prismatic item he had obtained earlier and secretly looked at it.

To be honest, I don't really understand what this thing does.

The symbols on it are completely meaningless. No matter how high the IQ is, I don't know anything about the text. It's just as useless.

The only thing he could feel was that it was extremely cold to his hands.

That symbol, he'd only seen in two places. One is the entrance when you come in. However, there are fewer symbols there, and they are single.

The other had seen it in the sword he had taken from the monster's belly.

He was bored at this point, so he took the black sword from his back. Because there is no scabbard, this sword, he is directly tied with cloth and carried it behind his back.

When two things are put together. Fu Hao was suddenly stunned.

Because in Fu Hao's impression before, the long sword was black, and the arrow-shaped item obtained was dark blue.

There is a big difference between the two.

And one is clean, and the other is taken out of the animal's body, which is quite dirty. So I didn't think about it at all.

But at this time, when they were put together, he suddenly found that the width and shape of the two were almost identical.

Fu Hao put the arrow edge on the tip of the sword and compared it. Because colors tend to give the illusion of different sizes.

But when they are put together at this time, they will find that this dark blue arrow edge is almost like the one that was broken off the blade of the sword just now.

In fact, Fu Hao looked at the sword carefully and also found such a situation, the sword body was also one grid at a time, and each grid was the same size as the blue arrow edge in his hand.

And those cells have a single little marking, which seems to be used for counting.

"Could it be that this thing was taken from this sword?"

Fu Hao was a little difficult to believe.

He then placed the dark blue arrow edge on the head of the longsword, and the two were indeed a perfect fit.

In fact, the sword, in many civilizations, is definitely not as simple as a weapon.

This is true in ancient and modern times, both in China and abroad. From Europe and the United States to China. Even Japan. The Japanese have always loved Japanese swords, but in fact the Japanese imperial family uses long swords of the same shape as those of China. And not a katana.

That kind of long knife with a bend is actually used by people who go to the battlefield to fight hard.
