My brother is so cunning.

The high-speed rotating heart-saving nail turned into a stream of light again and hit the same position of the huge monster.

The monster had been attacked once before, but because the damage was not high, the wound was very small, the nerves were dull, and the skin was rough and fleshy, so it only roared twice in pain.

After receiving the same attack again, it suddenly became violent, opened its bloody mouth, and roared at the two people in the air.

Its two hind legs, as thick as giant trees, were bent tightly, and it looked like it was about to leap into the air and bite the two "little flying insects" that were harassing it.

Compared with the behemoths that are tens of meters tall, the size of Wen Rui and Huang Tianhua as normal human beings is so different in proportion that it is normal for the behemoths to regard them as bugs.

"The difference doesn't seem to be that big..." Huang Tianhua muttered with some disappointment: "The beast you chose is too big. It seems that the Heart Nail is not suitable for fighting large opponents."

As soon as he finished speaking, a sudden change occurred, and large bumps bulged inexplicably on the surface of the monster's body, as if something was scurrying around inside its body.

The big bulging bag quickly collapsed and bulged again in another place. As the big bag rose and fell, black blood began to gush out of the monster's qi orifices, and the amount of bleeding became larger and larger.

The open mouth of the monster became the largest spewing mouth, and the monster spit out tons of plasma. The more it spit out, the thicker the plasma became, and you could see that it was mixed with meat sauce and visceral fragments.

As flesh and blood continued to spit out from its mouth, the giant beast deflated like an inflatable doll, leaving only a layer of skin and slowly deflated.

At this time, the heart-saving nail penetrated the animal skin and flew back to Huang Tianhua's hands.

Huang Tianhua released his spiritual consciousness and scanned the remains of the monster, and then he understood the damage caused by the nail just now.

The flesh, bones, and internal organs under the skin of the giant beast were all twisted into bloody mud!

The whole monster, with its relatively complete organs, only had its skin left.

Huang Tianhua looked at the magic weapon in his hand in disbelief. He had used this heart-saving nail countless times, but never so cruelly.

The monsters in the Demon Realm that hit a monster with skin as tough as iron would have such terrifying lethality that if it hit a human monk, no intact skin would be left behind.

This treasure can no longer be called a "heart-saving nail", it should be called a "meat-grinding nail".

"Brother Wen, how did you do it?" Huang Tianhua looked at Wen Rui like a monster: "In just a few months, you have improved this magic weapon to such an extent. It is simply incredible."

At this point, he paused and his eyes became more complicated: "No, in the past few months you have spent a lot of time teaching me the interception teaching materials. You have not spent much time studying magic weapons in private, and the actual time invested is not much."

"Don't make a fuss. It's not like you don't know. I've been smart since I was a child."

Wen Rui calmly pressed his hands to show his humility and said: "It is not difficult to have the Tao, but it is not difficult to master it. I have received systematic Jie Jiao education, and after professional Jie Tian Enlightenment training, I have improved The magic weapon is not easy to use, just pick it up with your hands."

"I just slightly changed a few spells, how could the power be increased so much?" Huang Tianhua was still surprised and asked: "Can you teach me and help me solve my doubts?"

"Spin, I added spin!"

Wen Rui shook his finger: "The magic formula is like a programming language. Each word represents some kind of heavenly rule. The moral master teaches you the magic formula. The first part of the code is used to find enemies, and the latter part is to save the heart. Nailed edited Weierstrass function ballistic trajectories.”

"What? What did you say? Spin?"

Huang Tianhua understood the word "rotation" after listening to Jun's words and Sheng's words for a while.

"In the Fajue programming language, I added an angular velocity variable along the central axis of the cone that can accelerate infinitely."

Wen Rui didn't care whether he understood or not, and continued on his own: "Into the Weierstrass function ballistic trajectory, a variable for ejection steering in a limited space was added."

"The specific external manifestation of this newly added magic code is that after the high-speed spinning heart-saving nail is injected into the target's body, it will continue to eject and turn in the body until the ejection trajectory covers more than 90% of the area inside the space."

"The killing effect is that the high-speed rotating cone continuously forms a cavity effect, crushing every inch of flesh and blood of the target until its body is smashed into mud before it breaks out."

After listening to Wen Rui's explanation like a duck listening to thunder, Huang Tianhua showed a look of disappointment.

Originally, the substantial strengthening of the magic weapon should be a great joy.

In the last battle with the Demon King, if he had used the new method Wen Rui taught him, he would never have lost that battle.

Huang Tianhua was not afraid anymore when he encountered a monster with huge size, strong body and amazing recovery power. Once the nail was nailed down, his flesh and blood were smashed into mud. No matter how strong his vitality and how fast he healed, he could still crawl in a short time. If it doesn't get up, it can be sealed and imprisoned.

But he was not happy at all.

Recalling that many years ago, when he went down to Qingfeng Mountain to join the world to assist King Wu of Zhou to destroy the Shang Dynasty, and when his master, Daode Zhenjun, gave him a magic weapon, he felt very complacent.

I just feel that the world is so big and there are so many treasures given by Master around me. Whatever my heart desires, I can go wherever I want.

But at this moment, he had also obtained a powerful magic weapon, but he felt extremely disappointed.

After all, no matter how powerful the magic weapon is, it is not his true ability.

Only the wisdom like Wen Rui, who can double the power of a not-so-powerful magic weapon with slight improvements, is the real skill.

"Brother, don't be discouraged. You have a good attitude towards learning during this period and have worked hard. You have completed half of the nine-year compulsory education series. It can be seen that you have a talent for reading."

Seeing him like this, Wen Rui hurriedly offered his emotional value: "With the improved heart-piercing nail, ordinary demons are no match for you. I will continue to stay with you and teach you more advanced knowledge of Jiejiao's "mathematics, physics and chemistry". After you study for ten or eight years, you can also reach the level of self-study of the law like me."

"Mathematics, physics and chemistry?" Huang Tianhua's eyes lit up and said: "Brother, it is because you have learned mathematics, physics and chemistry well that you are so smart and wise, as if you understand all the truths in the world."

"Of course!"

Wen Rui patted his chest and guaranteed: "Teacher Tongtian once said: 'Learn mathematics, physics and chemistry well, and you are not afraid to travel through the three realms' . "

"Mathematics can help you understand the laws of nature in the most objective way. Physics can help you summarize the laws of nature. Chemistry can help you understand matter correctly and transform the world. "

"If you learn these three subjects well, even an ordinary person can know everything, let alone a god like you?"

Huang Tianhua tightened his hand holding the nail and nodded heavily, saying, "Brother, don't worry. Leave the defense of the Demon Realm to me. I also want to thank you for your company and teaching. Listening to your words is worth more than five hundred years of wasted time!"

He stood proudly in the sky, overlooking the vast mountains of the evil Demon Realm, and said loudly with determination, "As long as the Demon Realm is in chaos, I will not return to Mount Tai. When this world is pacified, I can also learn from you the secret of 'mathematics, physics and chemistry' that is not afraid of traveling through the three realms!"
