Although each ghost is nourished by black qi, they are still sluggish and look weak.

Hei Yan turned his head to look at Gu Lan, then looked at the execution ground, touched his head, and said to himself: "Why is this wooden lump so daring." ”

Lin Chen was ready to start fighting at any time, but he saw something muttering in Hei Yan's mouth, and then turned to leave.

Just as Lin Chen was relaxing, Hei Yan suddenly turned around again, his eyes were like torches, and he shouted: "You lied to me!"

Gu Lan was also awakened by Hei Yan's voice, no longer trembling, and looked at the furious Black Yan in front of him.

Lin Chen was helpless, so he quickly took off his filial piety clothes and handed them to Gu Lan, so as not to break them during the fight, and he had to rely on this thing to hide his identity.

"In the middle stage of the opponent's cultivator, judging from the outbreak just now, it should be the law of the earth that is cultivating. The little blind man reminded.

"Is it the middle stage of the cultivator? It's just right, just to test the combat strength of my scholar's late stage of cultivation. After Lin Chen finished speaking, he summoned the water god Fury and took the initiative to meet him.

"I haven't finished talking yet, as long as he hasn't learned to ......" The little blind man's words were not finished, but Lin Chen had already flown up.

Seeing this, Heiyan crossed his arms in front of him, spread his legs apart, and stood firm with a horse step. He whispered in his mouth: "Lithification!"

There was a crisp sound, and Lin Chen's spear stopped in front of Hei Yan.

Although Lin Chen was surprised, he immediately used the power of the rebound to draw a circular trajectory in the air with the spear, and stabbed towards the black rock again.

There was another crisp sound, and Lin Chen's spear was bounced back again, and Lin Chen's hands were numb from the shock.

Lin Chen's water god fury is made of metal, and after hitting something hard, it will naturally be shocked. Don't underestimate the power of this anti-shock, if you don't know how to unload the force, it is easy to be injured, and the stronger the force you used before, the stronger the anti-shock force will be.

As a halfway monk, Lin Chen also felt such a strong shock for the first time, but due to his lack of experience, Lin Chen did not know how to unload the force, so he could only hold the barrel of the gun, for fear that the spear would get out of his hand.

At this time, Lin Chen's eyes were staring at Heiyan tightly, trying to see what was going on, his gun was obviously firmly rooted in the opponent's abdomen and arm, how could it have no effect at all, could it be that the other party also had something like a water shield?

Hei Yan lowered his arm, twisted his arm, and said, "The strength is okay." ”

Is this still a human being? Even the cultivation of the Fox Fairy Seventh Grandmother was injured under the wrath of the water god, and this black rock actually had nothing to do, Lin Chen was shocked in his heart.

"It's my turn. Black Rock collided with his fists twice, strode forward, and his right hand smashed up and down towards Lin Chen like a hammer.

Looking at Heiyan's big man of more than two meters flying in the air, the explosive muscles of his whole body tensed, Lin Chen couldn't help but think of the ape Taishan in the movie.

Lin Chen rolled on the ground to dodge, and Hei Yan's fist smashed firmly into the ground. However, Kuroiwa's fist was indeed too fierce, and most of his right arm was directly inserted into the ground.

Lin Chen and Gu Lan were both shocked, this is so powerful, if they are hit by this punch, it will be completely cold.

However, before Lin Chen and Gu Lan could make their next move, Hei Yan had already started his own performance.

"Ah...... Yikes...... Hey ......"

Lin Chen and Gu Lan immediately took two more steps back, their legs tensed, and the cat raised their waists, waiting for Hei Yan's next round of attacks.

However, after a few more strange sounds, Kuroyan suddenly exhaled and said, "Stuck." ”

"Poof, hahahaha......" Gu Lan suddenly laughed out loud and said happily, "This big guy is so interesting." ”

Although Lin Chen really wanted to figure out how this guy resisted his spear, this was the Ghost Prison, even if he abolished this guy, there were more powerful characters, and he didn't come here to fight.

So Lin Chen hurriedly walked to Gu Lan's side, took his filial piety clothes and put them on his body, and continued to hurry.

"Little blind man, what happened to that black rock just now, how could it be that he couldn't even pierce the water god's anger?" Lin Chen asked.

The little blind man thought for a moment and said, "First, there is still a certain gap in your cultivation, of course, you can make up for it with the wrath of the water god, this is not the main problem. Second, your water god rage is water attribute, and you just used the Lin family's marksmanship, which is not strong enough. Thirdly, the law he cultivated was the law of earth, and it seems that his main possession was the ability to turn into rocks and the like. The last one, the attributes are mutually restrictive, and you must know the truth of soil and water. ”

Lin Chen nodded slightly, as a lover of ancient Chinese culture, Lin Chen naturally understood the principle of the five elements.

In China, ancient people believed that everything in the world was composed of the five basic elements of gold, wood, water, fire, and earth, which is actually a way to recognize the natural world.

Just as modern science considers atoms to be the elementary particles that make up everything in the world, and modern education has worked tirelessly to have all students memorize the periodic table. At the end of the day, it's also a way to understand the natural world.

Although the Five Elements Theory seems untenable from the perspective of modern science, it still has a wide range of applications. For example, the broad and profound Chinese medicine has widely used the theory of the five elements, the theory of mutual growth and mutual restraint.

Wood makes fire, wood is warm, fire lurks in it, drill and burn out, so wood makes fire; fire gives birth to earth, fire can burn wood, wood burns into ashes, ash is earth, so fire gives birth to earth; native gold, gold dwelling stone is born by the mountain, jin run, gathering soil into a mountain, the mountain will be feldspar, so the earth is born of gold; gold is born of water, less yin qi, moist and dry, and the gold is also water, so the mountain stone is moistened, so gold gives birth to water;

To put it bluntly, wood gives birth to fire, fire gives birth to earth, earth gives birth to gold, gold gives birth to water, and water gives birth to wood.

The nature of heaven and earth, many are better than few, so water is better than fire. Essence is better than strong, so fire is better than gold. Rigid and soft, so gold wins wood. Specializing in the dispersion, so the wood is better than the soil. The real is better than the virtual, the homeland is better than the water.

This is the five elements of mutual restraint, to put it bluntly, it is water to overcome fire, fire to overcome gold, gold to overcome wood, wood to overcome earth, and earth to overcome water.

Of course, this does not mean that everything in the world is so fixed, because in addition to the "five" character, the theory of the five elements also has the word "line".

The word "line" can be understood as movement, and the "five elements" refer to how the five factors of gold, wood, water, fire, and earth in all things in the world interact, move, and derive.

From this point of view alone, ancient Chinese philosophy is much more advanced than that of foreign countries, or at least it is already a dynamic cognition.

Although Lin Chen really knows a lot about the theory of the five elements, he really doesn't have a clue how to use Lin Chen. Just like the little blind man said, the science of later generations is to educate people and use a microscope to see the world, but they don't know that everything in the world is not as simple as particles, and Lin Chen lacks a set of theories in understanding all things.

Lin Chen once asked the little blind man for these theoretical methods of his predecessors, but the little blind man did not give them, so that Lin Chen could understand by himself, after all, the task of the little blind man was not to teach Lin Chen, but to understand the changes in the world through Lin Chen, and it was not suitable to interfere too much.

"Those ghosts are on fire when they encounter fire, they should be of wood attribute. My water god anger is water attribute, then I use the water god anger to stab the ghost, with the principle of aquatic wood, the ghost should enjoy it very much. ”

Hearing Lin Chen's muttering, the little blind man rolled his eyes for a while, thinking in his heart that this little dusty man should not think about these things stupidly.

"Brother Lin, what are you talking about?" Gu Lan also heard Lin Chen's whisper and asked.

"Ahh Lin Chen said casually.

"Oh, the Five Elements. Guran responded.

When Lin Chen heard this, Gu Lan actually knew the Five Elements, so he asked, "You also know the Five Elements?"

"Of course I do, my father taught me these things when I was a child. Guran said.

Lin Chen immediately became interested and asked, "What about the five elements?"

"Isn't it wood that gives birth to fire, fire to earth, earth to gold, gold to water, and water to wood, and water to fire, fire to gold, gold to wood, wood to earth, and earth to water. Guran said casually.

It seems that the little blind man really didn't lie to himself, this Five Elements Theory has existed for a long time, and even the people in this world know it, Lin Chen thought to himself.

"What about Tukeshui, what about water?" Lin Chen asked.

"What a coincidence, when my father told me that the Five Elements Technique was endless, I asked him this question. Guran said.

"And how did he answer?"

"My father took me to the river, and found a very large stone and threw it in, but it was immediately swept away by the current, and then he found another stone and put it near the water, and in a year he said that in a year it would be scratched like all the other stones on the bank. ”

Lin Chen's eyes lit up, and he fell into deep thought, carefully understanding the meaning of these two sentences.
