At this time, a disciple of the Longquan Gang said suspiciously: "Our gang leader only has a baby daughter, and there are no other relatives, how can there be a more suitable person to carry out the blood sacrifice." ”

"Don't worry about it."

Zhong Lifei said as he stretched out his hand to unravel the acupoints of the disciples of the Longquan Gang.

Then, he smiled and said, "Go back and tell your helper that Zhong Lifei is going to visit the door, please prepare him early, and don't neglect the two of us." ”

The eldest brother who regained his freedom asked, "What about the little junior sister?" ”

Zhong Lifei replied, "Everyone, please rest assured, Miss Ning will go to the Longquan Gang with us." When the time comes to the blood sacrifice, I will give a satisfactory solution. ”

These disciples will be suspicious, but no one dares to snatch the little junior sister back from the hands of the master and apprentice.

After glancing at each other a few times, under the leadership of the senior brother, they went back to Ning Zeyang to report what had happened.

Seeing that the group was gone, Chu Fan said anxiously: "Master, wouldn't it hurt her to take Miss Ning back now?" ”

Zhong Lifei said with a grin: "I just said, even if it is a blood sacrifice, there is no need to make Miss Ning pay the price of sacrifice. ”

"Huh?"

Chu Fan was surprised, and suddenly his eyes lit up, thinking that he had guessed the master's intentions.

He suddenly snickered and said, "Master, you don't want to push Gang Master Ning into the furnace, do you?" ”

"Please, don't do that!" The kind-hearted Ning Xiaoyan screamed in fright.

"Don't be nervous, I still have to ask your father to help me reshape the unicorn bone, how can I harm him?"

After explaining his intentions, Zhong Lifei continued with a calm face: "Actually, I have already found a victim to replace the living. ”

"Really?" Ning Xiaoyan's eyes were full of anticipation.

"Of course."

Zhong Lifei nodded, and pretended to be mysterious: "Your father only knows about blood sacrifices, but he doesn't know the key reason why iron ore can't be melted. I know all about this, and I will not be able to solve this problem. ”

Hearing this vague but affirmative reply, Ning Xiaoyan showed a reassuring smile.

Chu Fan noticed that there was an almost narrow color in the master's eyes, as if he had compassion and pleasure after seeing the world.

He couldn't help but widen his eyes.

Suddenly, Chu Fan really thought of what the hell the master was thinking in his heart.

He hurriedly pulled the master aside and asked in a low voice, "Do you want to use animals instead of living people for blood sacrifices?" ”

Hearing this, Zhong Lifei had an incredible expression on his face.

"Apprentice, you are more and more impressed by the teacher."

Then, in surprise, he asked, "Tell me, how do you guess the mind of the teacher?" ”

"This ......"

Chu Fan was stunned for a moment and couldn't answer.

The reason why he guessed correctly was because he just remembered a person who taught him chemistry in high school.

This chemistry teacher is interested in history, and often combines allusions and stories from ancient books to explain chemistry knowledge in class.

Therefore, Chu Fan listened to it with relish, and he still remembered the knowledge that the teacher had said.

He remembered that the teacher had brought up the legend related to the blood sacrifice in class and gave him a scientific answer.

In ancient times, charcoal was used to smelt metals, and the burning temperature could only melt metals such as copper and tin, but it could not meet the needs of iron smelting.

The melting point of iron ore is higher, and the ancient swordsmiths are even more powerless against it.

But there are living examples of how iron ore can indeed be melted into iron paste after a blood sacrifice.

It looks very metaphysical, but if you put it bluntly, it is not mysterious.

According to scientific explanations, burning living people together with charcoal can play a role in supporting combustion and increasing the temperature of the furnace.

This is because when fats, carbohydrates, etc. in the human body are burned in the furnace, a lot of carbon is released.

After the chemical reaction between carbon and iron, the steel that the ancients dreamed of was developed.

Steel is harder than copper and iron, making it more suitable for casting a sword of superior quality.

Moreover, steel swords have the characteristic of not being easy to rust, which in the eyes of the ancients seemed to be a symbol of aura.

It's just that this method is too cruel, and the swordsmiths of the past generations have regarded it as a forbidden technique.

It will not be used unless it is absolutely necessary.

At the same time, the ancients believed that spiritual energy existed in human flesh and blood, and that only the weapons cast by living people could have spiritual energy, and even stubbornly believed that the life of those who were dedicated to their loved ones had a high probability of casting the most spiritual sword.

Only Chu Fan, who had crossed over, knew in his heart that in fact, putting animals such as cattle and sheep into the furnace could have the same effect of fueling.

But Ning Zeyang doesn't understand science, and mistakenly believes that animals have no spirituality, and it is a great disrespect to the gods to use them for blood sacrifices.

At this time, Chu Fan was a little difficult, and he didn't know how to explain this scientific truth to his master.

As a last resort, he made up a lie.

"Master, I picked up an ancient book before, which records that the effect of blood sacrifice with live animals is the same, so I boldly guess that you are going to use animals instead of Miss Chu for blood sacrifice."

"Ah, there is such a good book? Take it out and show it to the teacher. Zhong Lifei asked.

"Whoever goes out will take a broken book on the road, of course they will stay in Xuanwumen."

"So, I'm going to take a good look at this book when I go back, there must be a lot of mystery in it that is worth studying."

"I didn't know it was a good book, and I thought it was all nonsense."

The master and apprentice talked and laughed, and took Ning Xiaoyan on the road.

Unbeknownst to them, the horses had been on the road for less than a quarter of an hour, and a large group of men and horses were galloping towards them.

Ning Xiaoyan, who was riding a deer with Chu Fan, looked up and was so frightened that he lost his face on the spot.

A large group of people rushed towards them, and the person at the head turned out to be her father Ning Zeyang!

"So impatient!"

Zhong Lifei, who saw the situation clearly, grinned and motioned for everyone to stop and wait for each other.

Coming to the master and apprentice, Ning Zeyang dismounted and saluted and said, "The presence of the head of Zhongli really makes our gang shine. ”

As soon as the simple polite words were finished, he urged his daughter to go back with him.

It turned out that after this guy received the disciple's report, he immediately panicked.

He spent the belly of a gentleman with the heart of a villain, thinking that Zhong Lifei's decision to solve the blood sacrifice was to prevent him from casting a peerless divine weapon.

Therefore, Ning Zeyang hurriedly led his disciples to come, for fear that Zhong Lifei's master and apprentice would take their daughter away and fly away, and there would be nowhere to find them.

Seeing that Ning Zeyang was so impatient, Zhong Lifei knew that the other party did not believe that he could successfully complete the blood sacrifice.

So, he explained his intention to Ning Zeyang with a smile.

Ning Zeyang was suspicious, and his eyes were bigger than the copper bell.

After a long time, Ning Zeyang came back to his senses and muttered, "Don't you really need the little girl's cooperation in this matter?" ”

Zhong Lifei said with a smile: "I once met strangers on the road and taught the supreme Taoism, so that I can know astronomy and geography, yin and yang gossip, Qimen Dunjia, all of them are fine, all of them will not know, just blood sacrifices, what a foot Tao!" ”

Suddenly, the expressions on the faces of the many Longquan Gang disciples at the scene froze.

Look at what you said, in heaven and on earth, there seems to be nothing you don't know, how can there be such a character in the world!
