In a moment of desperation, Wang Daoyuan thought of the physics knowledge he had learned in his previous life.
After all, he had received higher education. He had studied sound waves since junior high school, and he was still studying them when he was in university. He was not completely ignorant about sound waves.
However, the laws of this world were different from those of his previous life. When he was young, he had tried to use the chemistry knowledge he had learned in his previous life to do something, but without exception, he had failed.
For example, he once wanted to generate electricity to create Thunder Talismans. In the end, this world could not generate electricity at all.
In this world of cultivation, the principles of matter seemed to be different from his previous world.
Therefore, he wasn't sure if the knowledge he had learned in his previous life to weaken sound waves could be used in this world. However, at this time, there was no other way. He could only try everything he could.
According to what he had learned in his previous life, the transmission of sound required a medium.
For example, air and water. However, the transmission of sound across the medium would consume a lot of energy. The greater the difference in density between the two mediums, the more sound energy would be consumed. With less energy, the sound would naturally become softer.
For example, if someone was riding a horse in the distance, so far that the sound of the horse could no longer be heard.
The effect of sound traveling on the ground was better. If one's ear was on the ground, one could clearly hear the sound of horse hooves. However, if one's ear was off the ground, one would not be able to hear it. This was because sound traveled from the ground to the air. It was transmitted across a medium, and its energy was depleted. The sound was too soft for human ears to detect.
As for the specific principles behind it, it had been several years since he graduated from university in his previous life. Twenty years had passed in this life, so he had long forgotten all about it.
However, knowing the principle was not important. What was important was knowing what to do.
If he knew something like the Earth Wall Technique, he would be able to condense spiritual energy and turn it into a solid object. Then, he would be able to create an earth ball to wrap himself up. Unfortunately, none of the talismans he refined were of this type.
The armor condensed from the Earth Armor Talisman, the Gold Armor Talisman, and the Water Dragon Armor were all in the form of spiritual energy, not solid. The only non-gaseous thing he could condense was a water ball.
Wang Daoyuan made up his mind to take a gamble. If he could weaken the sound wave attack, then he would kill this old bastard. If it didn't work, then he would immediately use a mid-grade Tier 2 Divine Strider Talisman to escape.
Circulating his water spiritual energy, he controlled the water in the underground river to form a water ball. This layer of water ball didn't wrap around his body tightly, and there were some gaps between it and his body.
He was still worried about a single layer of water ball, so he condensed an even bigger water ball and wrapped it around the outside.
Between the two layers of water balls, there was a half-foot gap, which was filled with water spiritual energy.
The sound of the bell had to pass through the air and travel to the outer layer of the water sphere. Then, it would travel from the outer layer of the water sphere to the space between the two layers of water spheres. Then, it would travel to the inner layer of water sphere. Finally, it would travel to the air between the human and the inner layer of water sphere. Only then could he hear it.
If this principle worked, then after four consecutive transmediums, the sound of the bell wouldn't even sound like a fart.
Not only did Wang Daoyuan not retreat, he even took a few steps forward, as if he was about to attack.
The black-robed old man controlled the yellow bell to ring again.
As a precaution, Wang Daoyuan still took a few big steps back to avoid being severely injured by the sound wave if this principle was ineffective. He would not even have the chance to escape.
The two of them were only a few dozen feet apart, and the sound of the bell arrived in an instant.
The outer layer of the water sphere was shaken by the sound of the bell. The entire water sphere seemed to be boiling, but the inner layer of the water sphere only had small ripples.
When the sound reached Wang Daoyuan's ears, it was like listening to the sound of a bell dozens of miles away. If he did not listen carefully, he would not be able to hear it at all.
If this principle worked, Wang Daoyuan was especially happy: "As expected, it didn't sound like a fart. Old man, just wait for me to chop you up."
The black-robed old man saw that Wang Daoyuan was not affected by the sound of the bell at all, and was somewhat in disbelief. He activated the yellow bell a few more times, but it still did not have any effect.
On the contrary, he was the one who activated the magic tool consecutively in a short period of time. His body was affected by the recoil, and he spat out a mouthful of blood.
After a few breaths, Wang Daoyuan was already in front of him.
The black-robed old man asked in horror: "How can you not be affected by the sound of the bell?"
Wang Daoyuan did not reply, and directly used the Water Dragon Technique. A water dragon appeared and wrapped around the yellow bell.
The water dragon flew towards him with the yellow bell. He took the yellow bell and directly sent it into the space of the Spiritual Pearl.
Even if the black-robed old man had a connection with the magic tool, they were separated by space. No matter how capable he was, he would not be able to sense the yellow bell, let alone activate it.
After removing the greatest threat, Wang Daoyuan dispersed the two layers of water balls. The Water Dragon Technique once again turned into the Water Dragon Armor. Coupled with the Golden Armor Talisman and the Earth Armor Talisman, he was not afraid that this injured old man could do anything to him.
He knew very well that villains died from talking too much. Although he was now a righteous person, he still had to be steady and send this old man to the afterlife first.
He took out the Profound Yang Sword, and without saying a word, he slashed down.
It was unknown if the black-robed old man was injured or something, but his movement technique was terrifyingly weak. He was actually unable to dodge this simple sword strike, and only had time to move his head away.
This sword strike landed on his left shoulder.
Although the Profound Yang Sword was not very sharp, it still depended on who it was cutting. It was almost enough to cut a python or a crocodile with a thick skin and a thick body of scales, but cutting this old man was like playing with a toy.
With one strike, the black-robed old man's entire body was almost split into two halves. He did not even struggle before he died.
Wang Daoyuan did not choose to search on the spot. He had good things on him, and after killing the enemy, he would plunder them on the spot. It was too easy to be plotted against.
The defensive talisman and the Water Dragon Armor were still on him. He lifted the black-robed old man's corpse, wanting to take away his storage belt.
Suddenly, a spirit beast bag on the black-robed old man's waist opened by itself, and a young rogue cultivator ran out.
Wang Daoyuan grabbed him and asked, "Who are you? Why are you here? "
Without saying a word, the rogue cultivator turned around and threw out a hidden weapon. Then, he turned around and fled.
This hidden weapon was the needle-shaped magic tool that was hidden in the black smoke when the black-robed old man spat out black smoke.
When the needle hit Wang Daoyuan's Earth Armor Talisman, the Earth Armor Talisman only trembled slightly. This power was far inferior to the one the black-robed old man used.
Wang Daoyuan was too lazy to talk nonsense with him. He directly chased after him and struck the rogue cultivator on the back of his neck. The rogue cultivator immediately fainted.
After all, he was only a guy at the second level of Qi Refinement. If he wanted to play tricks in his hands, he could dream on.
At this moment, the black-robed old man's corpse was still in his hands.
Wang Daoyuan directly opened the three Spirit Beast bags on the corpse, and after making sure that there were no people or Monstrous Beasts hiding inside, he put the three Monstrous Beasts inside, and together with the storage bags, he put them into the Spirit Pearl space.
Then, he put the black-robed old man's corpse into a storage bag and hung it on his belt.
The yellow bell was still in the space of the Spirit Pearl. Without knowing if this old man had a backup plan, he directly threw the corpse into the space of the Spirit Pearl. It was hard to guarantee that this old man would not leave behind a backup plan.
In case another rogue cultivator popped out from somewhere and directly controlled the yellow bell, when Wang Daoyuan's divine sense entered the space, it would attack him.
When one's divine sense entered and was attacked by the yellow bell, it might implicate one's soul.
It was better to be safe than sorry. Even if victory was in his hands, he had to be steady. It didn't matter if it was a little troublesome, but if he was careless and was plotted against, he would really die with regrets.
