Content of the Second Law of Thermodynamics (excerpt): It is impossible to extract heat from a single heat source to completely convert it into useful work without causing other effects, or the micro-increment of entropy in the process of irreversible heat is always greater than zero. That is, there must be a heat source and a ‘cold source’, and the entropy in the system is constantly increasing.

Bu Xianxian took the Demon-removing Blade that Yu Cheng Mo gave her and returned to her residence.

It was already late, and Bu Xianxian, who had no space equipment, could only walk back with the dazzling dagger, as if he was holding a lantern.

Originally, four disciples lived in a room in one room, and Bu Xianxian lived alone.

After closing the doors and windows, Bu Xianxian sat in the center of the room with the Demon-Elimination Blade.

He clumsyly pinched the clumsy magic trick and gathered a little spiritual power to point it on the spirit beads.

Boom! It seemed like it had exploded, and the snow-white spiritual energy spread throughout the room.

The whole room seemed to be covered with fog, and the fog was still thickening, and it was covered in white.

Bu Xianxian suddenly heard the sound of objects breaking, and felt that the speed of spiritual energy was surging faster.

Bu Xianxian remembered that Yu Cheng Mo said that this demon-removing blade was about to break, and it seemed that it was the sound of the spirit bead breaking.

After waiting for a while, the spiritual energy was released, and the spiritual energy in the room began to transform into the colorless natural spiritual energy of heaven and earth little by little.

The naked eye can no longer see it, but for the monk, he can feel that there is now a rich and terrifying spiritual energy in the room.

Although there were doors and windows blocking it, the spiritual energy was still spreading out at a slow speed. Bu Xianxian quickly sat down and began to breathe.

After taking a deep breath, a large amount of spiritual energy entered her body from her mouth and nose, and after walking around her meridians, she exhaled 90% of it.

And ninety percent of the spiritual energy seemed to have changed, no longer floating in the air, but crawled into the ground.

Bu Xianxian inhaled a full breath of spiritual energy and made the same mistake.

When you breathe in and exhale, you will naturally have vomiting and suction, and even vomiting is still in front of suction.

Nothing in the most famous and righteous way of the famous school does not take all the inhaled spiritual energy for yourself.

The cultivation world believes that the spiritual energy flowing between heaven and earth is slowly turning into another state and then immersing into the ground and reaching the center of the earth.

As for what will happen after entering the center of the earth, no one even explored the monks in the Tribulation Period.

After cultivating the spiritual energy between heaven and earth into the human body, circulate it in a specific way, and then exhaling it after practicing, it will speed up its transformation speed. A part of the spiritual energy will permanently become spiritual energy with the special attributes of the monk, becoming the cultivation level of the monk, that is, the result of the cultivation.

Where the concentration of spiritual energy is particularly high, the natural transformation speed is relatively fast. If used for cultivation, the proportion of achievements obtained by monks will also be greater.

There are some places in the cultivation world that are born with high concentration of spiritual energy, which are called the Cave Heaven and Blessings, and plants and ores with high concentration of spiritual energy are treasures of heaven and earth.

Yu Chengmo's Demon Elimination Blade absorbs the demonic energy and converts it. If it is released directly, it will automatically transform into ordinary natural spiritual energy, forming a small cave like a blessed environment in a short time, comparable to a treasure that cannot be eaten but can be recycled.

There are many sayings about demon cultivators in the immortal world, such as the practice of reversals and the meridians that go against the flow of the meridians, and the inner demon possession of the body and killing people into a crazy breakthrough without bottlenecks. In fact, there are rumors deliberately spreading.

As one of the closest people to the leader of Huanshi, Bu Xianxian knew very well what a real demon cultivator was.

Ordinary monks practice by promoting the spiritual energy of heaven and earth. The best skills and the best talents can generally only obtain 30% of the spiritual energy. Even when the spiritual energy is so rich that it is close to the limit of the monks' endurance, it has never been said that it can reach 50%. Ordinary talents like Bu Xianxian can only barely reach 10% even in the large amount of spiritual energy created by the Demon-Eliminating Blade, not to mention under ordinary environments.

The special feature of demon cultivators is that their demonic attributes are very different from those of the spiritual energy of heaven and earth, but they can "pollute" the spiritual energy and directly convert the spiritual energy into the magic energy, which can reach a conversion rate of more than 40%, or even up to 60%, or 70%.

The remaining part of the spiritual energy in the world did not sink into the ground like the normal method, but was consumed for some unidentified reason. This consumption also exists in normal practice methods, but the proportion is much smaller than that of the magic cultivator.

Moreover, the high-speed devouring of the spiritual energy of heaven and earth cannot satisfy the demon cultivators. They soon discovered that in addition to the spiritual energy of heaven and earth, they can also infect and transform the spiritual energy of other monks. Not only does the conversion rate also have a large advantage, but they also have a larger amount.

...Practice overnight...

Early the next morning, Yu Chengmo was waiting excitedly at the place where he agreed to gather. When he saw Bu Xianxian coming over and running over excitedly: "Is there a breakthrough, is there a breakthrough?"

After getting closer, Yu Chengmo sensed the aura of Bu Xianxian, and his pace suddenly froze: "The peak of Qi refining..." Bu Xianxian's current cultivation level is the peak of Qi refining stage, and he is less than the level of building a foundation with just one step.

"When I reached the last step, the spiritual energy in the room was astigmatized. I was blamed for being too slow." Bu Xianxian said a little depressedly, and handed the broken demon-removing blade in his hand to Yu Chengmo.

Yu Chengmo immediately blamed himself: "I blame me, I should consider this issue and help you borrow a spirit lock array."

The spirit locking array, which is the spiritual array that blocks spiritual energy and does not scatter, is a perfect match with the attributes of the Demon-Eliminating Blade. However, Yu Chengmo can absorb spiritual energy without barriers from the Demon-Eliminating Blade, so his place does not require such equipment, let alone the treatment of Buxianxian only for ordinary disciples.

He threw the broken magic-removing blade into the space bag in his arms, and Yu Chengmo took out a lot of magic-removing blades: "Please take these to defend yourself, take more, hang some on your waist, I have a bag here..."

When Zuo Qiuyin found that Yu Cheng Mo and Bu Xianxian got along, he inexplicably looked at Bu Xianxian with more than twenty shining demon-removing blades hanging like armor. Yu Cheng Mo was still stuffing a sheathless sword into her hand.

"With the self-defense handle, the mechanism of the evil-killing sword and the Demon-killing Blade is similar, but it can be used continuously. After the spiritual energy is fully stored, it can also use a big move, a half-meter-long sword energy!" Yu Cheng Mo said while stuffing the evil-killing sword in his hand into Bu Xianxian's hand.

"What are you using when you gave me the sword?" Bu Xianxian was already sweating. On the one hand, she started to struggle when Yu Cheng Mo hung the Demon Elimination Blade on her. On the other hand, the weight of these more than 20 Demon Elimination Blades on her body was also a great burden.

"Junior Brother Cheng Mo." Zuo Qiuyin's other disciples who had already acted together came over and felt their feet suddenly sink. It turned out that Yu Chengmo used the Nascent Soul Pressure to suppress Bu Xianxian, and then he pushed Bu Xianxian without any distinction.

"Senior brother, are you ready to set off?" Yu Chengmo asked, his hands did not stop.

"Well, everyone is here, are Junior Brother Cheng Mo ready?" Zuo Qiuyin asked.

"Of course I'm ready." Yu Cheng Mo took advantage of the fact that Bu Xianxian was distracted and stuffed the Xie Zhu Jie Sword into Bu Xianxian's hand, and then replied to Zuo Qiuyin with a smile.

"Junior brother." Zuo Qiuyin's expression became much more serious: "This action may require a direct confrontation with the Nascent Soul Demon Cultivator. Are you prepared? How did you practice the three moves taught to you by the master?"

"Test the martial arts exam in school, right? Why do you have to go around the corner?" Yu Cheng Mohun didn't care: "Come and retreat to a place and see me - the military chariots and talismans!"

Yu Chengmo pinched a handprint, and instantly the spiritual energy left the body, forming a group of weapons surrounding Yu Chengmo.

Not only swords, but also chariots and horses around Yu Chengmo were all ready to go, as if an army without soldiers holding swords.

"Go!" Yu Chengmo stretched out his hand and pointed in a direction from a distance to the sky.

Suddenly, swords, chariots and horses all started to fire, and flew towards the direction Yu Cheng Mo pointed, directly to the end of his sight before dissipating, and then slowly turned into the natural aura of heaven and earth.

The famous skills of the top ten sects and military cliffs are known as the best starting style in the cultivation world, and the military chariot talisman!

Because Yu Chengmo lacks cultivation talent and has no moves to inherit the evil-killing method, the world's cultivation sects have gathered three moves to teach Yu Chengmo, among which the starting style is the military chariot talisman of the military cliff.

Yu Chengmo's move was extraordinary, but Zuo Qiuyin frowned after reading it, obviously not satisfied.

"Junior Brother Cheng Mo, as far as I know, the military chariots are cultivators and spiritual weapons, why are you just sending the weapons out?" Zuo Qiuyin asked.

Yu Chengmo didn't care and waved his hand: "It doesn't matter. People follow the troops to quickly narrow the distance with the opponent and then use the next move. I must be killing in one move. If I need the next move, it's good to stand here."

Zuo Qiuyin's brow frowned even deeper: "The chariots and chariots are like troops. The battles are just soldiers moving forward. How can the generals hide behind and how can they get their momentum? If the generals and the morale are not revealed, they will be like a tiger's head and a snake's tail and cannot be of great use!"

Yu Chengmo complained with a bitter face: "Senior Brother, if you are from Junshi Cliff, I will certainly recognize me if you teach me this lesson, but you have heard of the key points of these moves, so why bother to be serious..."

After hearing Yu Cheng Mo's words, Zuo Qiuyin sighed: "Since that's the case, if you are ready, just leave." Zuo Qiuyin nodded, and suddenly a white light flashed in front of his eyes.

"Go!" A white stream of light shone towards the horizon, and Yu Cheng Mo's cheerful voice came back.
