Most of the books rescued from the fire were burned incomplete, but still have some information that could be obtained from them, and there was a lot of valuable knowledge in them.
Only there is mostly forbidden knowledge.
What is forbidden knowledge?
That is human experimentation, contrary to the knowledge of normal human decency.
Many of the books describe the anatomical study of the human body, the anatomical understanding of the blood form and so on.
There is also a description of the rune "extraction", through the "extraction" can be extracted from the essence of the biological body blood qi, forming a small piece of blood qi crystals, this extracted blood qi crystals, can help martial artists break through the bottleneck of blood qi strength.
Of course, the reason why it is taboo knowledge is because once a creature's blood energy is "extracted", it will die of vitality failure within a short period of time.
Su Hao guessed that the reason why the killer ghosts captured the population in the city was to extract the blood qi crystals, and then planted the seeds of "manipulation" on the dead bodies to turn them into puppets, which can be said to be two birds with one stone.
For Su Hao, regardless of whether these books are forbidden knowledge, he still reads them with great interest.
Since so many people sacrificed to gain the knowledge, learn it well, not let them sacrifice in vain. But let Su Hao use living people to do human experimentation, he will not do, replaced by animals and beasts and other alien races more or less.
The face of the alien, he will not be soft, the rabbit is cute, he did not hesitate to roast aromatic salt swallowed into the stomach.
Eight days later, Su Hao finished chewing all the books, a sense of satisfaction, but he still needs more data it's still not enough.
Next, Su Hao intends to start working on the runes.
He first took out the two black stones from the loot, and the two bottles of liquid.
The black stone was called black powder stone, and the two bottles of liquid were called blending grease. By grinding the black powder stone into powder and then mixing it with the blending grease, he got the drawing night used to draw runes.
This drawing liquid has a very good function of storing blood qi and will not let it volatilize easily, which belongs to the most common materials used by runesmiths to draw runes.
However, black powder stone and blending grease were not easy to buy, Su Hao had never heard of these two items even after staying in Ling Yun Town for so long, and they seemed very precious.
Su Hao knocked off a small piece of black powder stone and crushed it, then poured out a little thick blending grease, added a little water to dilute it, mixed it together and stirred it, the black stone powder actually became lighter with the naked eye, and finally completely faded to transparent and got a colorless sticky liquid.
This liquid is to draw the liquid.
Su Hao observed for a while and then gave instructions to Little Light: "Add the task, hand drawing strong light runes."
From the killer ghost's information, the four beast patterns, only the strong light, barrier and extraction simplified into runes, can be directly drawn and used, while the "manipulation" beast patterns, in addition to being engraved in the body to advance to the clan, cannot be used directly as runes.
Sensing, a small point of light appeared in the palm of his hand.
He took a thin quill, dipped it in the drawing liquid, and began to draw along the route marked by the small light.
It looked simple, but it was not. Not only did he have to use the drawing liquid to draw a complete rune, but he also needed to control the blood qi along the stroke at the same time, just like the runes etched in the body by elite advanced clerics.
To successfully draw a usable rune, the difficulty is extraordinary.
It is no wonder that the number of runesmiths is so small, it is not easy to draw with a complete pen, but also distracted by the control of blood qi, people who can do it are extremely talented.
Su Hao considers himself not very talented, at this moment is very glad to have the help of small light, otherwise let him draw this thing by himself, or give up before it is too late.
Little light's help is not the only thing, if not for the success of the last life to build little light, this information processing system, this life is estimated to be unable to successfully become a martial artist, through the early years of high-risk period.
Has come to this point, Su Hao only had a sense of security.
And this glimmer of security was surprisingly what he had exchanged for with an unknown number of transmutations and countless hours, which is not easy to think about.
Soon, Su Hao succeeded in drawing the "strong light" rune on his hand.
But this rune is not complete, at the end of the circuit, a small section is missing.
This small gap, like a button, when you need to stimulate the rune, you only need to use blood qi to fill the gap, you can immediately stimulate.
In other words, runesmiths are using drawing night mixed with blood qi in advance to draw a half-finished product first, and when they need to use it, they directly fill in the full excitation.
"It's quite convenient." Su Hao looked at the rune in the palm of his hand and nodded.
Then control the blood qi to fill the vacancy, in the moment of filling, the rune in the palm of his hand immediately excited, between energy transformation, burst out a strong light.
Like a flash for taking pictures.
Su Hao immediately analyzed the advantages and disadvantages of the rune.
The advantages are access to special power, easy to use.
But the disadvantages are very obvious, first of all, drawing is too difficult, the average martial artist is difficult to complete; secondly, drawn runes, even if there is blood gas at any time to maintain, but the longest preservation time is only three days, three days later, drawing liquid deterioration, the runes will be useless; furthermore, the same rune, can only exist at the same time a, otherwise will interfere with each other; finally, the cost is too low, spend a lot of time research, the obtained Runes, the strength of the effect is not as high as imagined.
Therefore, the rune is a piece of chicken ribs.
Unless ...
Su Hao thought of a possibility.
That is to use one of the more special runes - extraction, to make a breakthrough in the martial artist's blood qi bottleneck!
"Nope! I thought that the academy didn't have an 'extraction' beast rune before, but now it seems that it's not that there isn't one, but it's not open to the students, which means that I can't let other people know that I have an 'extraction' in my hands."
Su Hao's heart jumped first and immediately decided not to show the 'Extraction' beast pattern easily.
By sacrificing other vicious beasts or people to extract the required blood qi crystals for breaking through the bottleneck of blood qi.
No wonder runesmiths are classified as taboo, most runesmiths use runes as an aid to level up martial artists.
Su Hao read this point, in this world, runes are only auxiliary, it is too difficult to use runes to form a powerful combat power.
Immediately after that, he rubbed his chin and started to seriously analyze.
"In another direction, if I can do things that people in this world can't do easily and make the disadvantage of runes negligible, then the runes will be able to greatly enhance my hard strength."
A very simple truth.
The purpose of drawing night is to store runes for a long time.
Why do you need to store runes for a long time? Because it can't be distracted from making it when fighting, it can only be made in advance and used at any time.
What if Su Hao was able to draw at any time while fighting?
Then there would be no need to draw liquid. When you want to use it, draw it directly on the spot.
Is it hard to draw in battle? For others it is difficult, but for Su Hao, it's not necessarily difficult.
He didn't need to think, he just needed to control the blood qi to follow the navigation of the small light.
It was completely possible to shorten the time to draw runes through practice.
A bright light flashed in Su Hao's eyes.
"Then, try to practice!"
Two days later.
"Success!" Su Hao didn't need drawing liquid and successfully drew a 'strong light' rune in his palm, and the moment it was successfully drawn, it burst into an intense light.
"It took ten seconds! But keep practicing, the speed can be even faster." Su Hao's open hand was clenched into a fist.
His idea is feasible.
...
Today he planned to go out to collect material information.
After coming to town, he heard a news that made him freeze.
The killer ghost appeared again three days ago, and also took a dozen people captive every day?
Su Hao's first reaction is impossible, that the murderous ghost's chest was almost his entire cut, in eight out of ten could not survive, survived, how long has it been, and come out again as a demon?
Or is another person inherited the title of the killer ghost and ran out to commit a crime?
It could be possible.
He couldn't understand, so he stopped paying attention and started wandering the streets and alleys, asking one by one about materials.
As for the murderous ghost, if he runs into it again, he will cut off the other person's head with his own hands.
