Very reasonable cultivation

Banyue Mountain is located to the north of Tianjia Village. It has two crescent-shaped peaks with smooth cliffs that can form echoes.

There are many locust trees here, all of which grew naturally and are unevenly distributed. The trunks are thick and the crowns are even wider. This also leads to many dead branches under the crowns. They are either slender branches due to lack of sunlight, or thick dead trees that have fallen down at the end of their lifespan.

Tian Zhen and Da Zhuang came here under the scorching sun that was gradually rising. As soon as they arrived at the shade blocked by the Half Moon Mountain, Tian Zhen, who was holding a gong, couldn't help shivering and stopped moving forward.

This place was discovered when he and his father came here to collect wood. Although it is not in the sun, it is abnormally cold, so it has been marked as a key target.

Standing in the shadow with the sun behind you, it is convenient for emergency escape in case of abnormal situations.

Seeing that the retreat route had been simply arranged, he signaled Dazhuang to put the drum on the wooden stand he had brought, and took out two wooden sticks that had been polished smooth on the road, which were polished on the rough surface of the gong.

"Dongdong, tah!" He casually struck the wooden drum twice, then once on the edge, then said to Da Zhuang, "That's it. It's similar to when you're hammering iron. Just follow the rhythm in your mind. But with your strength, be gentle and don't use too much force."

Da Zhuang did not suspect anything. He took the two sticks handed to him by Tian Zhen, hit them twice tentatively, and then he mastered the appropriate strength.

I have to say that as a blacksmith, Dazhuang has a great talent in hammering. It only takes Dazhuang less than ten breaths to hammer out a rhythm.

Tian Zhen also picked up the gong and tried to strike the right rhythm. The process was slow. After all, he was a otaku in his previous life, and his knowledge of gongs and drums was limited to watching pigs run.

After Tian Zhen had a basic understanding of the rhythm of the gong, Da Zhuang could already beat drums with different rhythms. Tian Zhen, who was watching from the side, exclaimed in his heart: "Da Zhuang! Awesome!"

As a result, the entire Half Moon Mountain was resounding with the sounds of drums and gongs trying to join the rhythm.

The sound waves vibrated, and the drum beats continued to resonate and vibrate with the sound waves echoing on the cliff, forming sound waves that made the eardrums begin to vibrate. Maybe it was because of the sunlight behind them or because of the exercise, but Tian Zhen and the others felt a little hot.

In Tian Zhen's idea, the principle of resonance is to use the sound of gongs or drums to generate acoustic wave energy, which will resonate with the waves naturally emitted by the information in this area, thereby changing or modifying the information of those strange things themselves.

Whether the thermal radiation emitted by sunlight can participate in information resonance is not something Tian Zhen can prove.

What is the principle of resonance? If you place a row of pendulum clocks close together, no matter how asynchronous their initial swing frequencies are, they will eventually synchronize themselves due to the principle of resonance.

Although the existence of these ghostly creatures is still incomprehensible, they must obey the law of yin and yang balance. To put it more simply, "ghosts" can "move", and as long as they can "move", they cannot avoid interacting with other things that can "move", which is resonance.

"Sleep on you, get up and have fun!" Tian Zhen roared in his heart. Although he was sweating profusely and his ears were buzzing, he still swung the wooden stick hard to hit the gong, making it resonate rhythmically with the echoing sound.

He didn't know whether this would work or not, or whether his guess was correct. In short, there must be a mad fight between the man and the ghost. Damn, he won't be able to sleep well, and you guys won't have an easy time either, Tian Zhen thought viciously in his heart.

The sounds of gongs and drums continued until noon. Don’t ask if his hands were sore, Tian Zhen’s hands were sore and his stomach was hungry.

He had no choice but to move his things back to the village, and after eating at Dazhuang's house, he said goodbye to him and went home.

Da Zhuang watched Tian Zhen walk away. Ghosts were indeed a shadow in Da Zhuang's childhood. Since he encountered a ghost that day, he knew the feeling of having no control over his fate. He was naturally unwilling in his heart, but the general environment made him numb. Until Tian Zhen told him that he wanted to make those ghosts unable to sleep, the fire in his heart gradually shone with the sound of knocking.

The midday sun was scorching. Tiredly, Tian Zhen threw the gong to the door and just wanted to find a bench in the shade to rest for a while.

Looking into the yard, I saw a pergola. Under the pergola, I found my father and five-year-old brother lying on two recliners, one big and one small, enjoying the cool air and taking a nap. They looked so comfortable.

Seeing that they had a good rest, he was also impressed by their generosity. He returned to his room and took out a marked one with the word "Saltpeter" from the many bamboo tubes hanging on the wall.

This was also scraped off the outer walls of toilets in the village over the years. The amount is not much, just this bamboo tube.

Don't ask why they didn't make gunpowder and use the sound waves from the explosion to blast the ghosts. Tian Zhen had certainly tried that before, but it didn't work during the day, and it didn't light up at night. He realized that any carbon-based combustible would go out in front of the ghosts, and he knew his method wasn't working. He didn't know how they did it. Tian Zhen had considered using candles directly, but his father had warned him not to light candles in the house at night, as the moment the candles went out, the ghosts would come right in behind him.

Although the words sound alarmist, he is a good boy and naturally has to listen to his father.

Therefore, this saltpeter is temporarily useless against ghosts. At least we have no idea how to use it now. It can only be used to cool down in the summer, but it can be reused repeatedly.

After all, explosions also have their shortcomings. There is only one sound, but resonance takes time.

He filled a wooden basin half with water and poured in one-fifth of a bamboo tube of saltpeter. Suddenly, a cool breeze hit him. He hurriedly carried the wooden basin into the pergola, put four iron buckets filled with water in it, and then brought out his own recliner. Then, Tian Zhen also came to enjoy the cool air under the pergola.

From information he'd obtained from his father, he'd learned that this world existed as a place of immortals, and that their village lay within the borders of the Qiling Sect's Dayan Kingdom. Every city, town, and village was protected by immortal formations, protecting against demons, ghosts, devils, and other transcendental beings. This was why, despite the strange disturbances, they hadn't considered moving away.

There are abundant resources here, and the country exempts taxes below the town level, which is why the village survives in the cracks.

His father also boasted that when he was three years old, he was fortunate enough to see a long sword emitting golden light falling from the sky and landing in Half Moon Mountain during the day.

Although I feel a little tired physically, I am very excited and can't wait to see the results of today's efforts in the evening.
