Chapter 260

In the past three days, Li Changsheng has initially improved several steps of the blood vessel book, and successfully purified the blood of jianjiadilong, and successfully obtained the blood of brass dragon.

The blood of the Bronze Dragon is the same level as that of the black dragon. Due to the pure blood of the brass dragon contained in the jianjiadilong, it failed to purify it for countless times during this period, and the number of successful attempts was very small. As a result, Li Changsheng only got one brass Dragon blood vein in a test tube.

Even if the blood of the Bronze Dragon is absorbed by the goblin without blood, the blood of the brass dragon will be inferior.

In terms of extraction rate, it is about 5%. However, as long as he is skilled, Li Changsheng is confident that the extraction rate will be increased to 10%. As for the higher extraction rate, unless the first half of the book of blood vessels is collected, it is almost impossible.

In the end, several steps were replaced, and the extraction rate reached 10%, which is quite amazing, which is enough to prove the strength of the book of blood.

This time, Li Changsheng is ready to extract the blood of black dragon.

Li Changsheng first cut the heart of the venom dragon, releasing a large amount of blood essence, and then put a certain amount of boiling grass powder into the bucket sprinkled with the blood of the venom flying dragon.

The next moment, three barrels of venom dragon blood bucket began to boil, crazy gushing out a lot of steam, if you smell carefully, you can hardly smell the bloody smell.

Boiling grass powder can quickly evaporate the water in the blood without damaging the important components of the blood.

About ten minutes later, the blood of the three poisonous dragons stopped boiling. Under the magical effect of boiling grass powder, all the blood of the venom flying dragons condensed into a large dark red blood clot, which was the performance of a large amount of water loss in the blood.

these blood clot can be called the essence of blood, is also the first step to purify the black dragon's blood, although there is only one word difference with blood essence, but there are obvious differences between them. After completing the first step of the first technological step,

put Li Changsheng's blood essence into a specific container and gradually stripped useless magazines from the blood, leaving only pure blood vessels.

There has been a lot of research on the extraction of blood vessels in the world. There are many methods to extract the impurities in the blood gradually. However, many people are self-conscious and secretive. It is difficult to obtain a more profound knowledge of blood purification.

According to the extraction rate of the book of blood vessels, this is undoubtedly the top-level blood purification technology. Unfortunately, Li Changsheng only got half of it, so he had to use the knowledge reserve of Yuanling university to make up for the missing part as much as possible. This directly led to a sharp drop in extraction rate, but he was still in the category of top blood purification technology.

This is the power of the book of blood!

as time went on, Li Changsheng gradually put some powder, medicine and articles into it, and gradually extracted the magazines in the blood essence.

about an hour later, the original three barrels of blood essence has disappeared more than half, leaving only a small bucket of black and red thick liquid, under the illumination of light, can see faint threads of black brilliance.

The basic blood purification method has been processed, and the next step is the steps in the second half of the book of blood.

At this time, Li Changsheng took out a special potion and drank it with his head up. This is a special secret recipe from the second half of the book of blood. The production process is not complicated, which can make great changes in Li Changsheng's vision.

The next moment, Li Changsheng's pupil suddenly changed, as if it had become smaller than the tip of a needle, faintly showing a special light.

Looking at the black and red viscous liquid, Li Changsheng's vision was magnified to the extreme. The viscous liquid was constantly magnified until he saw a mysterious chain.

Thousands of blood chains are constantly intertwined and intertwined to form a huge and complex texture, which seems to be pregnant with a powerful force.

This is the blood chain belonging to the venom dragon. Its blood structure is huge and complex, which constructs a complex blood mark.

Among these blood marks, there are blood marks of various creatures, including those of black dragon.

In Li Changsheng's eyes, most of the blood chain is relatively dark, and they can not even be combined into blood marks.

There are seven different blood vessel marks in venom flying dragon. To put it simply, we can extract the blood vessels of seven kinds of creatures, including the blood vessels of black dragon.

In these seven different blood marks, Li Changsheng locked in the only one that radiated brilliance.

Even if he just looked at it, Li Changsheng could feel a weak pressure, and in the spiritual level, he could hear the sound of dragon chanting with dignity.

This is the blood mark of black dragon!

In addition to the blood of the black dragon, the other six kinds of blood can be described as worthless. Li Changsheng's next step is to extract the black dragon's mark as completely as possible, so as to obtain the real blood of the black dragon.

To purify the blood of black dragon, the simplest way is to remove the six lower blood vessels and complex blood chain, and finally only the blood mark of black dragon is left.

In the second half of the book of blood vessels, in addition to the special medicaments that can continuously enlarge Li Changsheng's vision, there are also several special dissolving agent formulations.These solubilizer formulations can be used to dissolve different levels of blood vessels, some for low blood vessels, some for medium and high blood vessels, and even a special dissolving agent that can be used to separate blood vessels at the same level.

The more complex the blood vessels in the goblin's blood, the more dissolving agents need to be used. Many of these dissolving agent materials are more precious, and the most expensive one is the devil's heart.

The higher the dissolving agent for higher blood vessels, the higher the demonic heart is required. For example, the dissolving agent for low blood vessels needs to use the heart of low demons, and the dissolving agent for medium blood veins needs to use the heart of medium demons, and so on!

The heart of the lower demons is cheaper, but the heart of the middle and higher demons is much higher, and it is difficult to find it in the market, which is mainly related to their strength.

"Fortunately, it's all low blood!"

Li Changsheng murmured to himself that he had a test tube made of demon core fragments, which had the advantages of transparency, hardness, heat resistance and corrosion resistance.

In this tube filled with green solution, without hesitation, Li Changsheng poured the dissolving agent into the black red viscous liquid.

Soon, under the sight of Li Changsheng, the dissolving agent began to work, wrapping up part of the blood vessels.

Under the effect of the dissolving agent, the structures of these blood vessels begin to collapse and dissolve, and finally turn into black precipitates, which fall under the bucket.

The process took more than ten minutes, and when the change was over, the black red viscous liquid was reduced by half.

Soon, Li Changsheng again poured a green dissolving agent, and finally extracted a bowl of blood emitting black shimmer, which is the so-called black dragon blood.
