The force is always mutual, this has been explained very clearly in the physics textbook of junior high school, you swing a fist at a wall, the force smashes into the wall, and the wall will also give the fist a force at the same time, which is a shock. You slide the water with the oars, and your arms give the water a force through the oars, which in turn gives you a force to push the boat forward.

The reciprocity of this power can also be applied to martial arts, Li Mi's Tai Chi method awakened from the subconscious, in fact, is playing a kind of deception of this power, your power directly hits, I use four or two thousand catties of ingenuity to dissolve, to put it bluntly, this is also a kind of guidance and diversion of power.

Not only that, this reaction force can also be used to explore the unknown, and the widely used geological radar of mankind is to create small shock waves to conduct in the formation, and then analyze the reflected bands to obtain the secrets of the earth.

A shock wave is a force that travels deep into the earth, rocks, waters, minerals, and ...... This force will be reflected back, and the wavelength bands reflected by different materials are also different, and what the geological radar analyzes is the difference between the reflected waves.

The same is true of Li Mi's fist, a punch smashed on the pear tree, and the power was transmitted to the earth through the trunk, and the power reflected back was completely different from his childhood memories, which was purely an intuition, a very keen intuition of a martial artist.

Li Mi's path as a martial artist was inherently weird, and the sudden appearance of white eyes and the deep meditation in the nutrition cabin gave Li Mi a very strong spiritual power, and his ability to perceive the mysterious power far exceeded that of the martial artists of the same period, and even the fighters in the transformation period were not his opponents.

Recalling the prospecting operation mentioned by the little six monkeys, and then looking at the back garden that has not changed in any way now, Li Mi felt a terrifying feeling welling up in his heart, he felt that there must be a secret hidden in the back garden in front of him.

Li Mi lay on the ground, his right fist hit the ground hard, and he felt the shaking of the earth with his body. Changing positions again and again, he had already discovered the strange source, and half an hour later, Li Mi rushed into the warehouse and took out a bunch of shovels and pickaxes and began to dig on the ground.

The location excavated by Li Mi is the hole where Liu Bo and the others found the lifeboat, and the military engineers camouflaged and backfilled the hole after digging, and everything has not changed as before the excavation.

The martial artist in the bone forging period used to dig the ground was really a bit overkill, but I saw that Li Mi's arm was like a hot wheel, and after a while, a deep pit appeared, and his whole person fell into the pit.

"Who? Who is digging a pit...... "After a familiar roar, the little six monkeys appeared in front of Li Mi, "Ah? What are you doing? Digging a hole to play on the big night? ”

Li Mi didn't talk nonsense when he saw that it was him, "Hurry up to your house and bring me a few miner's lamps, you must keep it secret......" Xiaoliu Monkey didn't say a word, and hurriedly ran home.

Just now, the little six monkeys used the money given by Li Mi to buy a lot of potions and send them home, and then thought about it, Li Mi was likely to go back to the old house to have a look, and the little six monkeys didn't tell their father that they came to Li Mi alone in the dark.

But I never expected Li Mi to dig his back garden in the middle of the night, but looking back and thinking about Brother Mi's current identity, there must be something strange about digging a pit.

With the joint efforts of the two, the depth of the pit soon reached about ten meters, and the little six monkeys who were tired of sticking out their tongues struggled to raise the iron pickaxe, only to hear a clang, the iron pickaxe seemed to hit the metal.

"Brother Mi! Metal underneath? And the echo......" The two looked at each other, threw away their tools, and began to clean the dirt with their hands, and when they had cleared out three or four square meters, they were both dumbfounded.

"Day...... This is actually a large alloy plate? It's still empty underneath! ”

Little Six Monkey didn't know how to get it, and all of a sudden, the hairs on his back stood up, "Secret...... Brother Mi! Isn't there something terrible down there, or how about sealing it up with an alloy plate? ”

", what's a terrible thing, you've watched too many zombie movies, right? I'm sure I definitely didn't have this alloy plate when I was a kid...... You're trying to get a metal cutter, I'm going to open him......"

Li Mi took a short break when the little six monkeys went back to steal tools, sat on the bottom of the pit and smoked a cigarette to smooth out his train of thought.

When Li Mi was young, his adoptive father once told him that when he was eighteen years old, there would be a super surprise birthday gift for him.

But the adoptive father kept shaking his head, just not telling him what this mysterious gift was, and in the end, he was really annoyed, so he told Li Mi that the clues of the gift were actually hidden at home, and you could play it slowly as a treasure hunting game.

In his childhood, Li Mi was very a treasure detective, and even the ant nest in the back garden was dug out outside the house, and the final result was, of course, nothing.

It is always difficult for the children's hearts to last long, and when they fail again and again, his mind to explore the treasure fades, and finally he simply forgets about it.

In the end, Li Mi's eighteenth birthday was spent in the martial arts hall, when his adoptive father had died of illness early, and the so-called mysterious gift eventually became a dream of his childhood, a kind joke by an adult to a child.

But today, when such a mysterious alloy plate appeared in the back garden, the floodgates of Li Mi's memory were completely opened, and the experience of exploring treasures as a child and the promise of his adoptive father came to his heart, and a sour feeling of missing his relatives burst out irrepressibly.

When the little six monkeys came back with the equipment on their backs, Li Mi's eyes were red and swollen.

"What's wrong with you, Brother Mi?" Xiao Liu asked in surprise.

"It's okay, I remember what happened when I was a child...... Let's get to work! Li Mi started the small metal cutting machine, put on the earbuds and saw the blade to spark a spark, and the alloy plate was deeply sawed open.

There was a huge friction sound in the earthen pit, the sparks were as bright as fireworks, and the saw blade was changed three times, and a round hole with a diameter of one meter appeared in front of the two, and the little six monkeys looked at the black cave and were scared all over with goosebumps.

The pillar of light of the miner's lamp pierced the darkness, and the circular tunnel was clearly visible, "Brother Mi!" This is really a tunnel drilled out of the landing craft, you look around the edge? How smooth it was, even the hard obsidian was cut open, and that prospect was real......"

"That's right, I understand now, after the hole was dug, someone supported an alloy plate with an iron frame ten meters above the ground, which was backfilled with soil and faked exactly like before...... What exactly is this group trying to cover up? What's in this hole? Li Mi said.

"Brother Mi, look, there's still a mountaineering rope here, and this group of people didn't even take their equipment away in the end! How rich they are......" A climbing rope appeared in front of him in the miner's pillar of light controlled by the little six monkeys.

"Don't think about it so much, I'll go down and take a look......" Li Mi jumped down from the cave after speaking, and grabbed the rope with a copy of his hand.

"Brother Mi be careful, if there is danger, hurry up......" The little six monkeys tried for a long time and didn't dare to follow together.

In the dark and deep tunnel, there is only the sound of Li Mi's snorting and panting, and the sound of condensation dripping and falling overhead, walking here, Li Mi feels like he has walked into the cave of the underground man in a fairy tale, and the darkness around him is like a substance.

The tunnels weave through the strata, with 90-degree rappels in some places, parallel gentle slopes in others, and even spirals around huge rocks in some places.

In a few places, the underground water system has seeped in, and streams of clear water have flowed down the tunnel into unknown places.

The tunnel was only 300 meters deep, but Li Mi felt like he had walked 3,000 meters or 30,000 meters, and when Li Mi saw the end of the artificial tunnel, he was already soaked.

At the end of the tunnel is a naturally formed stalactite cave, and a dark river flows and I don't know where it leads.

"It's all dug into the underground river! What exactly are they looking for? It can't be prospecting, and I haven't found a single piece of folded obsidian along the way, and it can't be meaningless to work on the work of landing craft drilling......"

There was a faint smell of sulfur everywhere in the air, but I didn't expect that there was a hot spring here, just next to a hot spring, Li Mi found something strange, how could there be an artificially dug platform in a natural stalactite cave, and there were dozens of special fixing bolts on the battleship on the stone slab.

Li Mi squatted on the ground and carefully measured the distance of the fixing bolt, and muttered, "What is it fixed?" What is important here that needs to be fixed? Why is it hidden under my house? ”

Li Mi didn't know why he was talking to himself, maybe the darkness of the underground world made him a little nervous, maybe he was just relieving the inexplicable fear in his heart, he didn't know that in the dark river behind him, a pair of orange eyes floated up, staring at Li Mi.

A triangular head with scales quietly poked out from under the water, its forked tongue rolled in the air, and the silent killer slowly climbed onto the shore and approached Li Mi tentatively.

This is a highly venomous underground sulfur lizard, the most feared and dangerous creature in the hearts of miners, dozens of people are attacked by this underground lizard every year in the obsidian mining area, and more than 90% of humans encounter this killer will inevitably die.

Li Mi didn't know that danger was coming, and the lizard approached little by little, ten, nine, and eight meters...... Approaching five meters of Li Mi's back, the sulfur lizard launched an attack at this moment, only to see a yellow lightning rush straight towards Li Mi's waist.

"Something!" Li Mi roared, and the warrior's instinct saved him at the last moment, and a lazy donkey rolled around narrowly avoiding the sulfur lizard's attack.

Li Mi picked up a sharp rock from the ground with his backhand, and smashed the head of the sneak attack lizard with a whoosh, but when he looked at Li Mi, his hair trembled with fright.
