In the end, Liuyun still ignored Tian Buyi's warning, and wrote two more words on the blackboard: Blood sacrifice.

"Do you know the difference between the two techniques?"

Song Daren shook his head in a daze: How can I know this......

Liuyun looked up at Tian Buyi, who was sitting at the end of the room, and asked with a smile, "Master, do you know what the difference is between these two techniques?" ”

Knowing that Liuyun could not be targeted, Tian Buyi frowned: Blood refining and blood sacrifice seem to be only one word different on the surface, but how do I think the two methods are very different, is this an illusion, or is there another reason......

Thinking of this, Tian Buyi raised his head and looked at Liuyun: "Then what do you say is the difference between these two techniques?" ”

Liuyun didn't answer directly, but asked a seemingly unrelated question: "Master, have you ever heard of the unity of man and sword?" ”

Tian Buyi nodded......

"Blood refining can strengthen the connection between man and sword, but it is limited to the process of forging the sword by the person who uses it himself."

"What about the Blood Sacrifice?"

Liuyun smiled slightly: "All the fierce weapons are contaminated with resentment, and their power has doubled. ”

Tian Buyi's eyes widened: "You mean ......?"

Liuyun smiled and nodded: "Some cult people, in order to refine the murder weapon, often use the blood sacrifice technique to massacre innocent civilians when they open the attack. ”

Tian Buyi was stunned for a long time before he came back to his senses and looked at Liuyun with a smile on his face: "What about the blood refining technique?" ”

"The human body is the spirit of all things, and it is born with its own aura, and the blood is the most abundant. Therefore, when refining a weapon, if you add a little bit of the user's blood appropriately, you can increase the power of the weapon. ”

Liuyun sighed, paused, and continued: "And the weapons used by our cultivators have higher requirements for aura, in order to increase the power of the weapon, a formation is also arranged on the weapon, at this time, if the method of blood refining is used, it can not only enhance the compatibility between the user and the weapon, lower the threshold for the use of the weapon, but also enhance the power of the weapon......"

Although Tian Buyi also felt that Liuyun was very reasonable, the method of blood refining has always been a taboo for decency......

For the sake of "popular science", Liuyun had to do it himself, and created a magic weapon according to the style of the shadow thorn, and when it was about to take shape, Xiang Tian Buyi asked for a drop of essence blood, which was melted into the vein of the essence gold formation.

Weapon Molding ......

Tian Buyi carefully took out the dagger from the cold pool water, and then froze there......

The blood is connected, like an arm.

This was Tian Buyi's first feeling after holding the dagger: this kind of feeling, Tian Buyi had only felt it on the Red Flame Sword that he had cultivated with his divine sense for hundreds of years......

Seeing that Tian Buyi was stunned holding the dagger, his face full of silver, Su Ru silently pulled out his Qingying Sword......

Seeing that the tragedy was about to happen, Tian Buyi came back to his senses in time and stared at Liuyun with a smile: "Apprentice, you have made a great contribution!" ”

Su Ru quietly closed the scabbard and stared at Tian Buyi with a gloomy face: "What the hell is going on?" ”

"Madam, the blood alchemy technique does have a magical effect......

Tian Buyi smiled and pulled Su Ru aside and began the advantages of Amway's blood refining......

But is it true that blood refining has no shortcomings at all?

Not really.

Weapons created with the art of blood alchemy have a natural attribute that excludes users outside the bloodline: this is equivalent to adding a bloodline identification device to the weapon, which cannot be used by non-bloodline descendants and cannot be given to the same family.

In this way, some powerful weapons have a foundation that is passed down from generation to generation, from father to son, from son to grandchild, and in the process of passing on weapons from generation to generation, the threshold for the use of powerful weapons is getting lower and lower, and future generations will also enjoy the legacy of their ancestors in weapons, and their cultivation speed far exceeds that of their peers......

Then, the cultivation world will gradually transition from the kind "Zen position to make the virtuous" to "the virtuous do not avoid relatives", and to the "family world" full of intrigues.

Then, there is a cultivation family in the cultivation world, there is "don't bully the young and poor", and there is "the old one who fights the small one......

After listening to Liuyun talk about the dangers of blood refining weapons, Tian Buyi quietly wiped the cold sweat on his forehead: everyone has selfishness, but with the excuse that "only blood relatives can use it", selfishness has become the norm; In the long run, the sect will be parasitized by the cultivation family, how can it last long?

Tian Buyi, who felt that he couldn't control his selfishness, suppressed the idea of reporting the blood refinement......

The refining class continued, and Song Daren, who didn't know that Qingyun "almost went astray", tirelessly absorbed fresh knowledge and theories every day......

Seeing that Song Daren's refining path was already on the right track, Liuyun discussed it with Tian Buyi and opened another alchemy class.

Unlike the refiner, Liuyun's first class did not have Amway's long history of alchemy, but only took out a large tome of "Detailed Explanation of the Medicinal Properties of the Kyushu Continent" and asked the "iQue" trio to take it back and memorize it......

After opening "A Detailed Explanation of the Medicinal Properties of the Kyushu Mainland", the "iQue" trio realized that there are more perverted things in feelings than a 5,000-word testimonial......

"That's more than 300,000 words!"

Wu Daren was so worried that he missed a steamed bun for lunch......

Although the "iQue" trio all felt that "A Detailed Explanation of the Medicinal Properties of the Kyushu Continent" was very perverted, it was not easy for Arita to supervise behind the three of them, and no one dared to be lazy.

"I knew that I would have listened carefully to the senior brother's talk about refining weapons."

"If you knew today, why bother in the first place!"

He Dazhi sighed, silently opened the book, and turned to page 230......

"Millennial ginseng, fire, warm, urgent, hanging......"

Carrying it on his back, He Dazhi became curious about "fire" and "sexual warmth": He Dazhi is clear that aura has attributes, but why do medicinal materials have attributes, and what does that "sexual warmth" mean......

In the early morning of the second day, He Dazhi found Liuyun with a bunch of panda eyes.

After asking what he meant, Liuyun didn't say much, took out two books from under the coffee table, and handed them to He Dazhi.

"The five elements are born and restrained from each other?" After He Dazhi opened the book on it and took a look, he put it below and picked up another one, "This is the contradiction between medicinal properties and medicinal effects?" ”

After that, He Dazhi "betrayed the organization" and regarded the endorsement as a pleasure every day......

More than a year has passed, and only He Dazhi and Su Ru, who are auditing, are left in the class of the alchemy class, and Tian Buyi, who is as anxious as fire, will be impatient to listen to it and find a place to cultivate......

Interest is the best teacher.

Interested in learning as a driving force, coupled with the assistance of superb IQ, He Dazhi took a step forward on the road of refining medicine......

Time is like water, and time is like a shuttle.

In the blink of an eye, ten years have passed......

Song Daren, who had already completed the study of refining theory, took over Liuyun's whip in addition to practice, and reopened the refining class to Wu Daren and Zheng Dali, who "can't support the wall with mud".

And He Dazhi, who had just completed the alchemy course, was preparing for the "final exam": under the premise of stipulating the medicinal effect, refining the pill according to the pill that lacked the number of medicinal materials......

He Dazhi, who was full of ambition, just glanced at it, threw Dan Fang aside, and then began to deduce Dan Fang......

"The efficacy of the drug requires hanging?" He Dazhi showed a hint of pride on his face, "The thousand-year-old ginseng is the king, and the medicinal materials of the ministers are mainly used to suppress the acute ...... of ginseng."

After estimating the number of various medicinal materials in his heart, He Dazhi took out the "examination tool" provided by Liuyun, and the three-legged medicine tripod was one.

Because there is no aura gathering fire plate like Liuyun, He Dazhi can only chop wood and make a fire by himself......
