Most of the books rescued from the brazier were incompletely burned, but some information can still be obtained from them, and there is also a lot of valuable knowledge in them.

But most of them are taboo.

What is taboo knowledge?

That is human experimentation, which violates normal human ethics.

There are many descriptions in the book about the anatomy of the human body, the anatomical understanding of blood and gas patterns, etc.

There is also a description of the "extraction" of runes. Through "extraction", the essence of blood and gas in the body of a living being can be extracted to form a small piece of blood and gas crystals. This extracted blood and gas crystal can help warriors break through the bottleneck of blood and gas strength.

Of course, the reason why this is taboo knowledge is that once the blood of a creature is "extracted", its vitality will fail and die within a short period of time.

Su Hao guessed that the reason why the murderer captured people in the city was to extract the blood crystals, and then planted the seeds of "control" on the dead corpses to turn them into puppets. It could be said that it killed two birds with one stone.

For Su Hao, no matter whether these books were forbidden knowledge or not, he still read them with gusto.

Since the knowledge acquired by so many talents has been sacrificed, we should study hard and not let their sacrifices be in vain. However, if Su Hao is asked to use living people to conduct human experiments, he will not do it. If it is replaced by animals, ferocious beasts and other alien races, it will be almost the same.

.

He would not show mercy when facing aliens. No matter how cute the rabbit was, he would not hesitate to roast it, sprinkle it with salt and swallow it into his stomach.

Eight days later, Su Hao finished reading all the books and felt a sense of satisfaction, but more importantly, he was still unsatisfied.

Next, Su Hao plans to start studying runes.

He first took out the two black stones and two bottles of liquid among the trophies.

The black stone is called black powder stone, and the two bottles of liquid are called blending grease. As long as the black powder stone is ground into powder, and then mixed with the blending grease, you will get the drawing night used to draw runes.

This drawing fluid has a very good function of storing blood energy and will not allow the blood energy to evaporate easily. This is the most commonly used material for drawing runes by rune masters.

However, black powder stone and blending resin are not easy to buy. Su Hao has stayed in Lingyun Town for so long and has never heard of these two items. They seem to be very precious.

Su Hao knocked off a small piece of black powder stone and ground it, then poured out a little thick blended oil, added a little water to dilute it, mixed them together and stirred, the black powder stone powder turned light visibly to the naked eye, and finally faded away completely.

, a colorless and viscous liquid was obtained.

This liquid is what draws night.

After Su Hao observed it, he gave instructions to Xiao Guang: "Add a task and draw a strong light rune on the palm of your hand."

Judging from the information on the killer ghost, among the four animal patterns, only strong light, barrier and extraction are simplified into runes, which can be directly drawn and used. However, the "control" animal pattern, in addition to being engraved in the body to advance to the master level, cannot

Use it directly like runes.

In perception, a small light spot appeared in the palm of my hand.

He took a thin quill pen, dipped it in the drawing night, and began to draw along the route marked by the small light.

It seems simple, but it is not so. Not only do you need to use the drawing night to draw complete runes, but you also need to control the blood energy to follow the edge of the pen at the same time, just like the runes engraved in the body by an elite advanced master.

It is extremely difficult to successfully draw a usable rune.

It's no wonder that there are so few rune masters. It's not easy to draw them completely with a pen, and they have to be distracted to control their blood energy. Those who can do it are extremely talented people.

Su Hao thought that his talent was not high, and he was very lucky to have Xiao Guang's help at this moment. Otherwise, he would have better give up as soon as possible if he had to draw this thing by himself.

Xiaoguang's help is not just that. If Xiaoguang's information processing system had not been successfully built in the previous life, it is estimated that he would not have been able to successfully become a warrior and survive the high-risk period of his childhood in this life.

After reaching this point, Su Hao felt a sense of security.

And this sense of security was actually earned by him through countless reincarnations and countless time, which is not easy to think about.

Soon, Su Hao successfully drew the "strong light" rune on the palm of his hand.

But this rune is not complete, and a small section is missing at the end of the loop.

This small gap is like a button. When you need to activate a rune, you only need to fill the gap with blood and it will be activated immediately.

In other words, rune masters use drawing and night to mix blood and energy in advance, draw a semi-finished product first, and then directly complete and activate it when needed.

"It's quite convenient." Su Hao looked at the runes on his palm and nodded.

Then he controlled his blood energy to fill in the gaps. At the moment when he was done, the runes on his palms were immediately activated, and a bright light burst out during the energy conversion.

Like a flash for taking pictures.

Su Hao immediately analyzed the advantages and disadvantages of the runes.

The advantage is that it obtains special power and is easy to use.

However, the shortcomings are very obvious. First of all, drawing is too difficult for ordinary warriors to complete; secondly, even if the drawn runes have blood to maintain at any time, the longest storage time is only three days. After three days, the drawing liquid deteriorates and the runes will be destroyed.

The text will lose its effect; furthermore, only one of the same rune can exist at the same time, otherwise it will interfere with each other; finally, the price/performance ratio is too low. After spending a lot of time researching, the effect of the rune obtained is not as strong as expected.

so high.

Therefore, runes are useless.

unless……

Su Hao thought of a possibility.

That is to use a special one among the runes - extraction, to break through the warrior's blood energy bottleneck!

"No! There should be an 'Extraction' animal pattern in the academy, but it is not open to students. In other words, I cannot let others know that I have an 'Extraction' in my hand."

Su Hao's heart skipped a beat and he immediately decided not to 'extract' the animal mark easily.

By sacrificing other ferocious beasts or people, the required blood energy crystals can be extracted to break through the blood energy bottleneck.

No wonder rune masters are classified as taboos. Most rune masters will use runes as an assistant to improve their warrior level.

Su Hao understood this. In this world, runes are just auxiliary. It is too difficult to use runes to form a strong combat power.

Then he touched his chin again and analyzed it carefully.

"In another direction, if I can do things that people in this world cannot easily do, and the disadvantages of runes can be ignored, then runes can greatly enhance my hard power."

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 you can't distract yourself from making them during battle. You can only make them in advance and use them at any time.

What if Su Hao could draw at any time during battle?

Then there is no need to draw the night. When you want to use it, you can draw it directly on the spot.

Is it difficult to draw during battle? It is difficult for others, but for Su Hao, it is not necessarily difficult.

He doesn't need to think, he just needs to control his blood energy and follow Xiao Guang's navigation.

It is possible to shorten the time of drawing runes through practice.

Su Hao's eyes flashed with light.

"Then, try practicing!"

Two days later.

"Successful!" Su Hao successfully drew a 'strong light' rune on his palm without any drawing fluid. The moment the drawing was successful, a strong light burst out.

"It took ten seconds! But if you keep practicing, you can get faster." Su Hao's open hand was clenched into a fist.

His idea is feasible.

…

Today he plans to go out to collect materials.

After arriving in town, he heard news that stunned him.

The killer appeared again three days ago and kidnapped more than a dozen people every day?

Su Hao's first reaction was that it was impossible. The murderer's chest was almost completely cut open by him. There was a high probability that he would not survive. He was lucky enough to survive. How long had it been before he came out to act like a monster again?

Or is another person inheriting the title of murderer and running out to commit crimes?

It's all possible.

He couldn't figure it out, so he ignored it and started wandering around the streets, asking one by one about materials.
