The bright moon hung in the sky, the light was shining, and although the night was deep, Li Cao did not feel sleepy. The lights flickered, and he sat excitedly on the side, carefully holding the pen handed to him by the teacher, the barrel of which was made of green bamboo in the academy, and it was verdant. I can't help but rub it all the time, and I can't put it down.

Li Cao took back the paper, ink, pen and inkstone from the teacher, as well as a booklet, on which various formation diagrams were recorded, from simple to complex, and complex formation diagrams would be broken down into multiple parts, and then written on the pages of the book, so that people could sort out the direction of the formation.

Zhao Hong has been teaching exercises in the classroom, answering doubts, and as the students embarked on the path of cultivation, he also began to teach how to set up a formation, of course, there is no simplified large formation. He didn't mention much about the formations drawn on paper, because after understanding the complex and huge formations, he would naturally be able to understand the pen and ink drawn on the paper, so he didn't want them to share their hearts before reaching the peak strength of the Spirit Manifestation Realm.

Li Cao and his classmates got the array paper given by the teacher and saw the power of the array paper, and they have always longed for it. After getting the paper, ink, pen, inkstone and formation book from the teacher, he returned to the schoolhouse, immediately picked up the book, and carefully flipped through it until night.

With a pen in his hand, he couldn't help but try to draw the simplest formation. An inkstone was taken out of the storage ring, and then a plum green willow leaf vase, a dark and shiny porcelain jar, and a small spoon were taken out in turn. Li Cao opened the lid of the porcelain jar, and the aura instantly floated out. Sure enough, as he thought, the porcelain jar could prevent the aura from dissipating.

Pick up a spoon, scoop a spoonful of spirit stone powder from the jar, pour it into the inkstone, and then close the lid tightly. Then pull the cork of the willow leaf bottle, and immediately the aroma is intoxicating, and the jade liquid is poured into the inkstone, mixed with the spirit stone powder. There is no need to stir, the two meet and become ink-like, but the color is different, crystal clear.

Spread the green leaf paper on the table, picked up the pen, and trembled slightly with excitement. Take a long breath, calm your mind, close your eyes, and silently think about the formation diagram to be drawn in your heart, so that you can move the pen smoothly. After thinking about it, I compared it with the book, made sure that what I thought was correct, dipped it in ink, and began to paint. It's a pity that the pen is completely different from the imagination in my heart, and when the painting is complicated, I can't control the stroke of the brush in an instant, resulting in the failure of the drawing formation.

Li Cao looked at the green leaf paper that he had destroyed, regretting it in his heart, and looked annoyed, because the teacher told him that a piece of green leaf paper was worth twenty taels of silver, and it was wasted by himself like this, which was really a tyrannical thing.

Li Cao sighed, although he knew that there was no way to save it, but he was still reluctant to touch the green leaf paper up and down. I was so impatient and conceited that I forgot the teacher's reminder to use ordinary paper when I usually practiced, and directly used Aoba paper to draw the formation, so that I lost twenty taels of silver. In fact, it is a waste to use Yuliquid Ling graphite, and I am not familiar with how to move the pen to draw the formation, and I will definitely fail. You should first use ordinary paper and ink to practice the movement of the pen to be familiar with the formation, and then use Yuye Ling graphite and green leaf paper.

Li Cao thought of it, put away the porcelain jar and willow leaf bottle, put the inkstone and the jade rabbit bamboo pen, and then began to grind, ready to stay up late to practice. After grinding, take the pen and paper and start drawing according to the simplest formation.

With the failure again and again, Li Cao gradually became upset, looked at the failed array paper again, couldn't help but crumple it into a ball, pinched and pinched, and then threw it out. Leaning back in the chair, closing his eyes, soothing his mood, he couldn't help but mutter, "This thing is much harder than writing." ”

Li Cao's mood calmed down, moved her wrist, encouraged herself, and began to continue practicing.

Time passed little by little, Li Cao became more and more proficient, and slowly was able to draw to the end, but unfortunately it always fell short, but this time I was not depressed, because I saw hope, as long as I persevered, I could succeed. As I finished the last stroke, I took a long breath, and the corners of my mouth couldn't help but rise, and I finally succeeded in drawing one.

Li Cao struck while the iron was hot, continued to draw, and kept repeating until he no longer failed, at least it didn't look like there was any obvious difference from the formation diagram in the book.

Before he knew it, it was dawn, Li Cao was still not sleepy, but a little excited, put away the ordinary paper that was spread all over the table, and then took out a piece of green leaf paper from the storage ring and solemnly put it on the table. Instead of putting pen to paper immediately, he stood up and walked up and down the room, twisting his wrists to soothe his muscles.

Almost half a stick of incense had passed, Li Cao sat back in his chair, eliminated distracting thoughts, picked up the jade rabbit bamboo pen, dipped it in the jade liquid spirit graphite, and drew a formation diagram with a wave. The hard work of the night is still worth it, and the pen is round and smooth. But at the end, there was a knock on the door.

"Big brother, you're up, do you want to go to dinner together?" Zu Zhenlin's voice came from outside the door.

Li Cao was concentrating, but he didn't expect to be disturbed at this time, and in surprise, his hand uncontrollably drew a long mark, and instantly thought that he had destroyed another piece of green leaf paper, and the twenty taels of silver were gone, and he couldn't help but collapse a little.

But there was nothing to do, I could only blame myself for my bad luck today, and got up to open the door for Zu Zhenlin.

Zu Zhenlin saw Li Cao's resentful face, and asked suspiciously, "What's wrong?"

"Alas, I lost forty taels of silver in one night. Li Cao said distressedly.

"What's the situation, was it stolen? Zu Zhenlin denied his speculation.

"Come in. Li Cao said.

Zu Zhenlin followed into the room, and immediately noticed the green leaf paper on the table, and saw the inkstone next to it and the crystal clear ink in it. I heard Li Cao talk about it before, and I felt very novel, because when I was at home, I had only seen the Heaven and Earth Great Array, and I had never seen the formation diagram used to fight.

"Are you drawing a formation, how is it, have you succeeded?" Zu Zhenlin asked curiously.

"Don't mention it, this is just being painted, it's about to be successful, you suddenly knock on the door, and then ......" Li Cao wanted to say and stopped.

When Zu Zhenlin heard this, he knew that he had disturbed Li Cao, but he didn't expect such a coincidence, and said with a smile: "Okay, if the painting is broken, I'll draw another one, come, hurry up and let me open my eyes." ”

Li Cao picked up the discarded green leaf paper and said bitterly: "This one is worth twenty taels of silver." ”

Zu Zhenlin felt funny, his brother has always been like this, although he is not a lover of money and stingy, but because he has been poor since childhood, he knows that money is not easy to come by, so he has been diligent and thrifty, of course, the money that should be spent has not been saved, but if it is wasted, it will be a little sad.

The two have different backgrounds, Zu Zhenlin has been clothed and fed since he was a child, and his life is worry-free, so he doesn't care about money, but this time he came out to practice, so he has a little more experience, and he can understand Li Cao's thoughts, but he doesn't want him to drill the tip of the horns, and sometimes he has to be a little better to himself.

"Okay, big brother, isn't it just twenty taels of silver? In this spring harvesting activity, you will get a lot of rewards, don't be too stingy, hurry up and draw, let me take a good look." Zu Zhenlin urged.

Li Cao knew that it was useless to be entangled, and he also wanted to know what his results were overnight, so he took out another piece of green leaf paper, picked up the jade rabbit bamboo pen, and prepared to wave it.

"Wait, big brother. Zu Zhenlin suddenly spoke again.

Li Cao was glad that he didn't put pen to paper, turned his head and complained: "If you cause me to lose one more, you have to compensate me." ”

"I just wanted to ask if I could speak out when you were drawing. Actually, I think it's better to make a noise, because you think, when you draw a formation in the future, you can't make sure that the surroundings must be quiet, and it's better to get used to it. Zu Zhenlin proposed with a smile.

Speaking when he was about to write was definitely deliberate, the intention was good, but he was still so fond of making trouble, Li Cao thought to himself.

"By the way, you should have just learned how to draw formations now, and you are not very proficient, so it's better not to be distracted. Zu Zhenlin didn't wait for Li Cao to talk, he talked to himself.

Li Cao couldn't cry or laugh, let him say anything, what else did he say? He could only continue to draw the formation and calm his mood, but before he put down the pen, he glanced at Zu Zhenlin again.

Zu Zhenlin smiled silently, stopped joking, and signaled that he would not make a sound.

Li Cao began to concentrate on the strokes, and the gestures were still as smooth and smooth as before, and there were no mistakes from beginning to end. He had a hunch that he had succeeded in drawing it, and his joy arose.

Seeing that he had stopped writing, Zu Zhenlin came up and looked at the formation on the paper curiously, "How is it, it succeeded?"

"It should be. Li Cao said that there was room for it.

"Then give it a try and see if it succeeds. Zu Zhenlin proposed.

Li Cao nodded, according to what was written in the book, this formation has no power, it is only used as an introduction to practice, and there is no need to worry about what the consequences will be, so it can be activated in the room. Holding the green leaf paper between his two fingers, he ran the exercises, and the faint green light flashed, and a flame appeared in the air, which was not hot and violent. Like a candle flame, it flickered twice and then disappeared.

After Zu Zhenlin saw it with his own eyes, he felt a little magical, and he had to admire the ancients, "Congratulations, you have succeeded." ”

Li Cao saw that the formation diagram he had drawn was stimulated, although it was not so magnificent and majestic, he was still full of joy, and said with a slight excitement: "Yes, I did it, I knew that I would definitely be able to." Alright, let's go have breakfast. ”

"Aren't we going to celebrate?" Zu Zhenlin asked with a smile.

"Forget it, it's not a big deal, when my realm is higher, let's celebrate at that time. Li Cao shook his head and refused.

"Okay, when Lin Xi's injury is completely healed, let's go out for a good meal together. Zu Zhenlin said.

Li Cao cleaned up briefly, and then went to the canteen to eat together, and after eating, brought some more to Lin Xi. After many days of recuperation, Lin Xi's face became more and more ruddy, his body was much better, and he could already walk normally on the ground, but it was still not suitable for strenuous exercise.
