"Come on, you try to break through this iron pillar again!"

With a loud bang, the old man of the town mayor didn't know where to carry a big iron pillar, weighing about a thousand catties, and inserted it directly into the yard, standing straight, signaling Lu You to try it again.

Lu...... Old man, you are taking revenge on me!

However, he couldn't say this, and he exhaled at the moment, and the iron sword in his hand stabbed straight into the big iron pillar opposite with a piercing sound of breaking through the air.

Sonorous!

The tip of the sword collided with the iron pillar, and the brilliant sparks splashed in all directions, and a white spot appeared on the dark iron pillar.

"It's not bad, you're trying to use your true qi to stab a sword with all your might!"

The old man nodded.

Lu You raised his breath and condensed, the strong true qi in the dantian was like an awakened angry dragon, pouring into the iron sword in the palm of his hand along the meridians of his arm, and suddenly, the ordinary iron sword emitted a crisp sword sound, and the purple light on it was entangled, and the sword was uncertain.

At this scene, the muscles in the corners of the eyes of the old man next to him twitched slightly, he seemed to have underestimated the solid foundation of the little guy in front of him, and fortunately, this little guy seemed to have never learned swordsmanship, otherwise, he really had nothing to teach!

Boom!

The lightning of the tip of the sword containing strong true qi pierced the iron pillar, and this time, the iron pillar directly hit by the terrifying power let out a roar of gold and iron, and the earth shook with it, and a white pit the size of a fist appeared on the dark iron pillar.

"Do you feel anything?" asked the old mayor.

Lu You frowned, and realized it carefully: "It seems that there is a feeling that I can't use all my strength, I obviously used eighty percent of my strength, but when the tip of the sword was sent out, there were only less than three points left, otherwise, this iron pillar should have been knocked out by a sword long ago!"

"Beautiful, that's right!"

The old man clapped his hands: "What I teach you is how to exert all the power in your body from the tip of the sword!"

Lu You was pleasantly surprised: "Can this really be done?"

The old man said proudly: "Of course, otherwise how can I be your teacher!"

"Xiao Lu, let me tell you, in the palm of our human hand, there are many acupuncture points, which connect all the vital points of the human body, for example, there are two hidden acupoints on this little finger, they connect our kidneys and life!"

"There are also palms here, there are two acupoint massages, which can improve the digestion of the body's large intestine, spleen and stomach, and there are countless examples. ”

"In traditional Chinese medicine, there is a tradition called acupuncture and massage, which is to treat all kinds of diseases through the body's acupuncture points, and in the same way, this principle is also suitable for us to practice swords. ”

The old man of the town began to teach earnestly, Lu You's eyes widened more and more, he never knew that sword practice could be linked to acupuncture and massage in traditional Chinese medicine, which was simply an eye-opener and increased knowledge.

"The blow you just hit with eighty percent of the strength, after the transmission of the tip of the sword, there is only less than thirty percent of the strength left, in fact, this is already very good, without real swordsmanship practice, to be able to achieve this level, it is already rare! Ordinary cultivators, most of them can only reach one percent, at most two percent!"

What the old man said made Lu You unbelievable again, at this moment, he felt that he was a frog at the bottom of a well, and his foresight was far from the real big man.

"The crux of this problem lies in the fact that on the palms of our human bodies, there are many hidden acupuncture points that hinder the transportation of true qi, and these acupoints are unknown to eighty percent of the cultivators in this world, and some of them are even difficult to find by many peerless powerhouses, but they really exist and affect the functions of the human body. ”

"And what we have to do is to open these obstructive acupuncture points, so that the true qi in the body can be exerted to the greatest extent, instead of eighty percent of the power, only thirty percent can be exerted!"

"Then old man, how exactly do you want to open the secret acupuncture on the palm of this hand?" Lu You asked curiously.

The old man of the town said: "Some acupuncture points are indeed difficult to open, but some acupuncture points are relatively easy, don't resist, raise your arms!"

Lu You obediently raised his right arm, the old man reached out and pinched it gently, and the next moment, Lu You clearly felt a strong True Yuan pouring into his arm, and then all the way down the palm of his hand.

"Look, at our wrists, there is an acupoint named Yang Valley, which is not usually used at all, but it is one of the biggest obstacles that hinders the transportation of our true qi!"

"Now, I'll help you untie it!"

As the old man's words fell, Lu You suddenly felt a pinprick pain in his wrist, and then the next moment there was a crisp sound in his body that seemed to be a balloon being punctured, as if some kind of level had been broken.

"Xiao Lu, you're trying to stab with your sword at the moment!"

Lu You grabbed the iron sword on the ground according to his words, and the true qi ran again, pouring the iron sword.

Buzzing!

The iron sword shook, surrounded by purple qi, Lu You's eyes suddenly lit up, and he felt that the true qi on his arm was running a lot more smoothly, as if it was originally just a canal drainage, but now it has become two, and the true qi is not congested and tense.

As his sword stabbed out, the strong wind suddenly rose, the sword broke through the air, and with a ding, sparks splashed on the iron pillar, and the power increased to at least one percent.

Don't underestimate this, its attack power is simply thrilling, and it is definitely a huge boost.

"Old man, you are really a god!"

Lu You was greatly surprised, and his eyes were full of admiration and admiration when he looked at the old man of the town.

"Hehe, this is just a little bit of a small way, Xiao Lu, now you take the iron sword in your hand as a part of your body, and try to stab again!" shouted the old man of the town.

Lu You followed his words, closed his eyes and stared for a moment, his true anger was agitated, and a sword stabbed out.

"No, you didn't do it at all, you didn't merge the sword with the body, you have to treat the sword as a part of your body, let's say it's your arm, he is you, you are him, you two are one!"

"Also, there is a problem with the operation of your true qi, when the true qi is swollen in the sword body, you have to let the true qi condense in the sword body for a certain period of time, so that the stronger the sword qi that bursts out, this is like a compression spring, the more you press, the greater the force of the rebound!"

"Again, it still doesn't work!"

The old man of the town town taught swordsmanship, as if he was a completely different person, strict and harsh, and Lu You continued it over and over again.

At the beginning, the old man of the town asked him to stab the sword with all his might, perhaps because the strength was too strong for Lu You to master, and finally retreated to the next best thing, letting Lu You only use the strength of his body to practice the sword.

Time passed minute by minute, a big morning had passed, Lu You was sweating profusely, his clothes were soaked, this morning, he had stabbed thousands of swords, each sword required a great deal of effort, it was more painful than a battle of life and death.

"Okay, let's practice here today, you will practice like this every day in the future, when you pass my requirements, it will be considered a success!"

The old man of the town opened his mouth and said, Lu You can be regarded as liberated, but although he is very tired, his heart is full of joy, this kind of learning knowledge is very beautiful.

If he had met such a famous teacher at the beginning, his achievements today would have been more than that!

dragged his tired body back to the iron shop, and unexpectedly, the food in the pot was still hot, and it was extremely rich.

"Thank you, Brother Detective!"

When Lu You devoured the meal, he thanked the criminal investigator who was watching silently.

The detective was silent.

"Hey, why haven't you made a fire today!"

Lu You suddenly wondered, at this time of the day, the stove outside was already very prosperous, but today it was quiet, and even the guy who struck iron didn't move out.

"Don't strike iron today, follow me to a place after eating!"

The detective spoke.

Lu You was stunned for a moment, and then rejoiced: "Is there a new high-standard point mission?

This time it was the turn of the criminal investigator to be stunned, the corners of his mouth couldn't help twitching, and suddenly his eyes moved, meaning inexplicably: "It can also be said to be a high-level task, as long as you can complete this mission, I will send you a hundred ...... alone No, a reward of two hundred points!"

"Two hundred points?that's a lot?!"

Lu You's eyes glowed green when he heard this, and he didn't even care about eating, so he threw himself directly in front of the criminal investigator, and said excitedly: "Brother Zhen, you are my own brother, hurry up and tell me where this task is?"

"Are you sure?"

On the criminal detective's dark face, it was rare to show a meaningful smile, but Lu You, who was excited, didn't notice it.

When he saw Lu You's sure nod, the criminal investigator shouted without hesitation, and then strode out of the iron shop.

The two walked out of the town and galloped all the way east, and after dozens of miles, finally, the criminal investigation who had been speeding in front of them stopped.

Lu You looked up in astonishment and found that there was a huge factory in front of him, and the two big golden characters on the factory were extremely eye-catching-Oil Factory!

Lu You raised his eyebrows, showing a little curiosity, but he didn't ask too much, and followed the criminal investigator into the oil factory.

As soon as I entered, a strong smell of oil came to my face, this factory is very large, covering an area of dozens of acres, and many workers are busy inside.

The detective seemed to be familiar with the place, turning left and right, and finally came to an open field covered with a tarpaulin.

Here, there were already people waiting, and when they saw the criminal investigator and Lu You coming, the waiting man shouted: "Brother Detective!"

The criminal investigator nodded slightly and asked, "Are you ready?"

"All set!"

The man spoke, and then glanced at Lu You lightly, I don't know why, Lu You always felt that the man's gaze was very weird, which made him inexplicably have a bad premonition.

"Let's get started!"

The criminal investigator ordered, with the order issued, a few men walked out in the distance, quickly uncovered the tarpaulin, and suddenly, a clear and transparent light curtain was refracted out, reflecting the entire factory building.

I saw that under the tarpaulin, a huge flat and smooth huge field was revealed, like a swimming pool, but it was many times larger than the swimming pool, and it was thousands of square meters.

In this specially made flat pool, a thin layer of bright light emerged, clear and transparent, and the light could be seen, Lu You looked at it intently, his eyes gradually widened, and he couldn't help but lose his voice and whispered: "Oil?"
