What would you do if you had a black notebook falling from the sky in front of you?

Write your name first, of course!

Ahem, flipping through the black notebook in his hand, there were experimental notes written in ancient languages, at least from the first few pages.

“... We drained all the blood from the Phoenix-Blood Knight's body and poured it into the normal body, but until the subject died, no reaction of bloodline power was detected from the subject, maybe next time we should try to use other knights with stronger bodies?..."

“... Mixing the blood of the Demon Beast with the blood of the human being, the serious blood clotting reaction that occurs, maybe there are other methods to be able to integrate the blood power of the Demon Beast into the human body, for the time being, the research on the Phoenix Blood Knight and the Dragon Blood Knight has not progressed, how did they come about?..."

“... If the power of the bloodline is not drawn from the blood, where does it come from?..."

The rest of the content is blank except for a few pages that can be clearly seen, and there is nothing worth caring about.

Luo Xiaotian had never seen any bloodline knights, so he didn't know what the phoenix blood knight and the dragon blood knight were. However, it seems that these people don't even have a concept of blood type, and they are trying to mix the blood of different species... To be bold is to be bold enough, but it shouldn't lead to anything.

This notebook was useless, and Brown and Christian on the other side were inspecting the pile of randomly stacked metalwork, hoping to find something valuable from it, but according to Luo Xiaotian's guess, those things should be used for experiments.

Leaving the cave, the three of them continued to go deeper, the sun not visible from the ruins buried deep underground, but the magic pocket watch that Brown carried with him could show the exact time.

Luo Xiaotian decided to buy one himself after he went out.

It's still early, and at least until it gets dark, and all three can continue to explore the ruins.

The two caves in quick succession were still full of materials and metalwork, but both times they were lucky, and the three of them were given some materials that were not of low value, whether they were used for themselves or sold for money.

"Wait! There's a secret door. ”

Christian, who was at the front, stopped, patted the wall next to him with his hand, and pressed one of his ears against the wall.

"It's a hollow inside, but I don't know how to open this secret door..."

Luo Xiaotian brought the light technique in his hand close to the wall, but in any case, he couldn't see any difference between this hollow place behind it and other walls, there were no gaps, and there was no difference in color, so he couldn't understand how Christian found out that there was a secret door here.

"Let me try!"

Luo Xiaotian's strength was definitely stronger than that of Brown and Christian, and he asked the two of them to stand a little farther away, and then leaned forward with his center, concentrating all his strength on his arms.

"Hah!"

As Luo Xiaotian gradually strengthened, he could hear the sound of stones rubbing against each other, and fine stone chips fell from the stone wall.

It seems that there is no problem, although I don't know the correct way to open it, but this hidden door can be pushed open.

Luo Xiaotian took out the power potion that had been placed on his body and swallowed it, and then quietly waited for the effect of the medicine to take effect.

Once again, in a posture that was easy to exert force, Luo Xiaotian pushed forward with all his strength, and there was a "boom" sound between the stone walls, and the heavy stone gate finally fell, making way into the cave.

The fallen stone door stirred up dust that had been on the ground for an unknown number of years, and when the smoke cleared, Christian was the first to enter the cave.

"Safe! ”

This is a larger cave than the one encountered before, it is said to be a cave, but when the light spell illuminates most of the area, it can be found that the walls here are different from the outside, and the obvious masonry structure means that this is probably part of some kind of building before, and the smaller caves before seem to be just storage rooms used by later people to store excavations.

That makes sense as to why this place looks so much like a mine cave rather than a ruin.

After telling the other two their thoughts, the three of them began to check the contents of the room separately. The magic lamp protruding from the wall further indicates that this place is different from the cave seen before, however, the magic lamp's energy source does not come from the magic crystal alone, but has undergone some kind of transformation, so the magic lamp in this room cannot be used at all.

But fortunately, this place is much smaller than the wide space on the previous floor, and the light magic of the three people is enough to light up all the space, Luo Xiaotian is interested in the bookcase, while Brown and Christian are more interested in the valuable magic items that may exist.

The wooden bookcase seems to turn into chips at the slightest touch, but perhaps because the room has been closed, the wooden doors of the bookcase are still working.

When he opened the door of the bookcase, there were stacks of books, most of which were broken by the wind caused by Luo Xiaotian when he opened the wooden door, and only three books were left intact.

Compared with the previous harvest, this harvest can be described as extremely rich.

Luo Xiaotian carefully took out the three intact books, and then flipped through the contents one by one, the first one was still an experimental note, judging from the content, these people finally discovered the difference between blood and blood, and began to use the original way to identify compatible blood types. However, even if they found the right blood, they still didn't get the results they wanted, and from the second half of the experimental notes, Luo Xiaotian even felt obvious despair.

Why despair? Shouldn't it be those who die because their blood has been drained?

The second book is not a notebook, but a book, a book about the local cuisine, which happens to be Vesta, the capital of the ancient Magic Empire, so the owner of this room is probably from Vesta.

Vista's ruins are definitely not here, according to the information Luo Xiaotian learned from others, Vesta, the capital of the ancient magic empire, is still buried somewhere underground in the Red Sun Desert, and I don't know when it will be able to reappear in the world.

In the Red Sun Desert, countless adventurers and desperate people hope to find the legacy of the ancient Magic Empire and gain inexhaustible wealth.

Flipping through this Vesta local food encyclopedia, there are many high-level Warcraft ingredients such as dragon eggs and fortress whale meat, which is unimaginable now.

There are some interesting things in this book, but there is no need to waste time here, Luo Xiaotian looked at the third book again.

This time, it's an essay.
