The moonlight penetrates through the stone windows, drawing spots of different shapes on the stone bed.

Xin Mu held two pieces of black yarn and looked at them carefully from beginning to end, trying to discover the secret on them. He didn't believe that Cang Yue had gone to great lengths to store in the tomb were only two ordinary pieces of black yarn, if it was two ordinary black yarns, why should they exist in the Upper Xuanyue Hall and the Lower Xuanyue Hall respectively, sealed in two jade boxes?

Xin Mu touched it with his hands, smelled it with his nose, bit it with his teeth, licked it with his tongue, and used all his facial features, but he didn't find a trace of difference. The silky and delicate, colorless and tasteless black veil is at his disposal in every way, ravaged in a thousand ways, without saying a word or fighting, silently blending with the darkness around him.

"What a broken thing!" Xin Mu scolded secretly, and threw out the black yarn, which fluttered lightly and hung on the window next to the bed.

The moonlight flowed silently like water, flowing through the black veil, casting some strange white spots.

"Huh?"

Xin Mu took a closer look, these strange white spots turned out to be some small white skeleton footprints, the five toes were clearly visible, and the direction of the skeleton footprints and toes was different, seemingly disorderly arrangement, and it seemed to imply some kind of mystery.

Xin Mu hurriedly took off the black veil and looked towards the moonlight, a string of strange white skull footprints appeared on the black veil, and the other piece was also the same white skull footprint, but five white words were reflected at one end - "Moonlight Ghost Shadow Step".

"Moonlight Ghost Shadow Step"?" Xin Mu looked at the skeleton footprints on the black yarn, and pondered carefully, the footprints? continuous footprints, is it a set of body methods? The body method is a necessary martial art for escaping and enhancing combat effectiveness, a good body method can not only produce more changes in the fight, but also can escape if it can't be beaten, even if it meets a powerful master, it also has the ability to live. Xin Mu suddenly became excited when he thought of this, and immediately jumped out of bed, and didn't care about putting on his shoes, and moved under his feet according to the white skeleton footprints on the black gauze, one step, two steps, three steps......

Although the footprints on the black yarn are not difficult to understand, it is quite difficult to translate into steps. The first step is very small, according to the proportion of the footprints shown on the black yarn, only half of the sole of the foot can be moved, Xin Mu gently lifted his foot, and then carefully fell, but found that the direction of the sole of the foot was wrong, his own sole of foot pointed forward, and the sole of the skeleton shown on the black yarn pointed to one side. Xin Mu retracted his foot, carefully felt, tried to adjust the direction of the soles of his feet, his body rotated half a circle, the direction of the soles of his feet was right, and the first step was successfully completed.

Xin Mu was overjoyed in his heart, and immediately learned the second step, but the second step was surprisingly big, so big that he couldn't take a step at all, even if he split a fork, Xin Mu had to jump and jump over. The next step is to move left and right, to the left and to the right, to lean your body to a very uncomfortable angle.

Xin Mu learned carefully step by step, like a child who had just learned to walk, his steps were naïve and clumsy, but his heart was full of novelty and happiness.

When he reached the sixth step, Xin Mu's body slowly leaned back, tilting to an extreme angle, his body suddenly lost balance, lost control, fell on his back, and "bang!" directly knocked over the table in the room.

Xin Mu got up, touched the back of his head that hurt, smirked twice, picked up the black yarn and continued to practice.

In the seventh step, the skeleton footprints suddenly changed in a strange direction, and no matter how Xin Mu changed the angle, he couldn't achieve it at once, unless he broke the soles of his feet.

The whole room fell into deep thought, and the four walls quietly looked at the people in the room, as if they were also attracted by this strange pace.

"What the hell is the footwork!" Xin Mu spread the black gauze on the window, crawled around on the bed, changed the angle to observe, thinking about all possibilities, until he thought of the middle of the night, he still couldn't find a clue, and finally fell on the bed, groggy and asleep.

"Bang, bang!" Xin Mu was excited, turned over and got up, only to see the sky outside the window faintly bright.

"Stinky boy! It's time to get up!" Yan Bo yelled as he banged on the stone window.

"Soul calling!"

"Stinky boy, get up, pick 200 sulfur grass today!"

"Damn, isn't it a hundred a day?"

"Who said that! That was yesterday's task! Two hundred today!"

Xin Mu picked up some dried meat, picked up the basket, walked into the yard, was unhappy, walked two steps, turned around sharply, and spit, "Phew!"

"Hey——! that's how it is! The seventh step of "Moonlight Ghost Shadow Step" needs a turn! hehe!" Xin Mu couldn't help but snicker, and quickly took out the black yarn, unfolded it to look at the sun, and there was not a single white footprint on the faint black yarn.

Xin Mu shook his head helplessly, and while advancing towards the Valley of Ten Thousand Pillars, he practiced the first seven steps of the "Moonlight Ghost Shadow Step" that he learned at night. On the cliff of the Ten Thousand Pillars Valley, Xin Mu couldn't help it, and wanted to show the pace of his new learning, but when he was doing it, he suddenly found that his body seemed to be much lighter, and climbing the cliff was not so difficult!

In the dusk, Xin Mu walked back to the stone house with a basket full of sulfur grass on his back and a dead snake in his hand. Yan Bo looked at Xin Mu with a smile on his face, and wondered in his heart, although there were no two hundred sulfur grasses in the latter's back basket, there were one hundred and fifty or sixty grasses, which was more than three times more than yesterday's harvest!

Yan Bo didn't ask much, drank the snake soup made by Xin Mu, and went to sleep by himself. Xin Mu also immediately went back to the room, took out the black yarn, and practiced "Moonlight Ghost Shadow Step" against the moonlight.

Step 8 and Step 9......

Xin Mu practiced step by step, his body flickering left and right in the room, flickering forward and backward, the speed became faster and faster, and the figure was sometimes dignified, sometimes blurred, and began to become erratic. The tables, stools, and some cabinets in the room were staggered and messy.

When he reached the eighteenth step, Xin Mu's body suddenly floated up, floated out half a zhang, left the ground, stepped on the wall with both feet, and actually stood on the wall. Xin Mu was overjoyed in his heart, he was about to fly off the wall! Just as he was about to take the next step, his feet suddenly stagnated, as if he had tripped over something, and he fell off the wall, and fell into the mud.

Xin Mu got up and looked at the place where he had just stood, the smooth wall, there were no grooves or bulges! What was the situation? He was strange in his heart, he took a new step and wanted to continue practicing, but suddenly felt that his legs were a little stiff, at first he thought that he had fallen from the wall and numbed his legs and feet, but after a while, his legs were still in a stiff state, not to mention practicing, even walking was very difficult.

"Not good!" Xin was taken aback, hurriedly sat on the ground, quietly picked up the "Chixia Decision" for pranayama, rested for most of the night, and his legs finally returned to normal.

"How could this happen? Could it be because he practiced this ghost step? Is this going mad! Is it wrong to practice like this? Or is there something missing?" Xin Mu thought secretly, but he couldn't understand that he had too little experience in practicing, and some of the most basic problems were all worldly problems for him. Before going to bed, he decided to ask Yan Bo tomorrow, and he concluded that the old man must know the truth.
