"Actually, Wen Cheng," Su Meng showed a hint of concern, "It's not good that you're in such a hurry."

"Su Meng," Wen Cheng looked at her and said, "Do you know how long I've been waiting for this moment?"

"Then there's no rush for this day...... Su Meng said.

"Su Meng, I'm not in a hurry to improve myself," Wen Cheng sighed, "I'm worried about Liu Zhen."

Hearing this, Su Meng lowered the corners of his eyebrows.

"Wen Cheng, in fact, I'm also worried about her, my physical strength is not good, and Liu Zhen has been hiding any troubles she has."

Wen Cheng bowed his head and was silent.

Even if she is the only great magician who penetrates the nuclear source with her own ability, she is still a weak girl after all.

"Su Meng," Wen Cheng raised his head and licked his lips, "Teach me, I'm really in good spirits now, I can't wait to go to Liu Zhen after I learn the offensive spell," he paused and said, "Although I know I'm still weak now, I can still do it if I take care of it."

Su Meng looked at Wen Cheng seriously, showing a wry smile of relief,

"Alright, come, stand up." She held out her hand.

Su Meng's body was very thin, Wen Cheng understood this, he gently held Su Meng's hand, put his weight on his legs, did not let the girl bear his weight, and tried to stand up slowly, only to find that his whole body was very numb, and he fell down again after a while.

After a while, he finally came to his senses, and the boy stood up straight, only to find that Su Meng had condensed the air into four crystals like transparent glass in the distance. Each crystal was the size of a human form, and the girl walked over to the boy after doing this.

"I'm sorry, Wen Cheng, I can only intervene in space optics and high dimensions," Su Meng said, "If I want to make a target, this may be something I can handle, can you see it?"

"I can see it." The boy nodded.

Although it is a transparent crystal, the light at the edges is staggered, gradually imprinting the outline of the crystal, and the crystal is filled with colorful vistas and sky.

"Wen Cheng, you can watch me demonstrate it first," Su Meng pushed his glasses behind his ear with his short hair on one side and said, "Although I'm not very familiar with the pure energy system, as a non-physical damage magic, this is also the basic skill of a magician."

The girl bowed slightly, making a standard posture to face the battle, the sleeves of the school uniform soon lit up with blue light lines, layer upon layer, ring after ring, the air made a slight humming sound, and the air flow rotated and intertwined around the girl's raised right arm, Wen Cheng looked at Su Meng and kept his eyes on the distance.

"Magic bullet, done!" The girl shouted calmly.

"Whoosh!" With a bang, the pale blue ball of light was compressed into a blue meteor that streaked in front of him.

"Bang!" The first target in the distance shattered like glass, and the residual sound echoed in Wen Cheng's ears like a starry sky.

"That's it," Su Meng soothed his expression and wiped the sweat from his forehead, "Actually, I'm not very good at pure energy, it would be much better if Liu Zhen came to teach you."

"It's okay," Wen Cheng smiled bitterly, "I saw it, but I didn't understand it......

"Wen Cheng, you understand," Su Meng said, "Didn't you draw a refining formation in your first year of high school?"

"You remember that......" Wen Cheng scratched his head and laughed.

"Remember," Su Meng said, "you showed me it at the time, but the principle is pretty much the same."

Wen Cheng nodded and waited for Su Meng to continue.

After Su Meng lowered his head and calmed his breathing, he raised his arm again and called out several glowing circles, which were wrapped around the girl's arm and glowed with a glittering blue glow.

"See, how many are there?" Su Meng raised his head and looked at Wen Cheng and asked.

Wen Cheng looked at the blue saucers in front of him incredulously and asked, "What is the principle of this?"

"No, don't worry about the principle yet," Su Meng shook his head and said with an uncomfortable face, "If you want to help Liu Zhen, you have to get started quickly and tell me how many there are."

"There are four in total." Wen Cheng looked at a piece of fluorescence and said.

"That's right," Su Meng gasped again after releasing the light streak, she swallowed her saliva and continued, "The magic bullet is the purest magic program, and it doesn't need to be deeply etched."

Su Meng slowly knelt down to the ground, stretched out his hand and drew one ring after another on the ground.

"This is the pattern," she said, pointing to the overlapping and interlaced light paths in the ring, "The first is compression, the energy density of the self-source is originally loose, and after passing through this compression layer from the loop, the source will be compressed to a higher density."

"That means it's endowed with higher energy, isn't it?" Moon Seung tried to keep up with the train of thought.

"That's right," Su Meng nodded at Wen Cheng and continued to point to the second ring, "The second is the blasting program, tell me, why is the second one a blast?"

"I think it's because the compressed energy only hurts when it is blasted." Wen Cheng answered quickly.

"Not exactly," Su Meng pushed his glasses as if he was wearing a white coat, "If you let the magic bullet be released freely, the attack range will be in all directions."

"Ah! I see," Wen Cheng quickly added, "The purpose of the blaster is to focus the direction of the energy release in front of it, so that there is no waste."

"That's right," Su Meng smiled and pointed to the third way, "Wen Cheng, what do you guess the purpose of this path is?"

"I can't guess, I don't understand this pattern at all." Wen Cheng scratched his head.

"You don't need to understand it, you can learn to use it, and I think it's the same thing when you develop programs." Su Meng said.

"I see." Wen Cheng nodded heartily.

Sure enough, the truth is the same, so what is the role of the third way?

If it's a fast-moving magic bullet that's compressed and the direction of attack is specified, then only ......

"I guess," Wen Cheng said, "is it to give kinetic energy?"

"No," Su Meng shook his head, "It's only half right, in fact, the fourth path is kinetic energy restraint."

"So......" Wen Cheng nodded his chin and looked at the sky, thinking for a long time.

"It's penetration." Su Meng looked at the boy's painful expression and said with a smile.

"Oh, yes," the boy smiled wryly, "If I don't have the ability to penetrate, I'm afraid the magic bullet will detonate when it hits a leaf in the middle of the flight."

"That's right," Su Meng nodded, "And the parameters of penetration can be adjusted by yourself, of course, the higher the coefficient, the higher the difficulty of etching." As for you, just use the default one."

"Well, I see, how easy it is."

Su Meng smiled, then pointed to the last circle.

"The fourth path is kinetic energy restraint, and as you said, the function of this program is to give kinetic energy to the tail of the magic bullet."

Su Meng stood up with a smile, clapped his hands and said, "Then Wen Cheng, are you ready?" Keep these four patterns in your mind, and then every time you release them, the pioneer will make your self-source quickly etched out with your mind on your arm, and the subsequent self-source will be obediently channeled into it."

"Oh my God......" Wen Cheng looked at the four circles on the ground and took a deep breath.

"Also," Su Meng added, "after this program is completed, it can be maintained, which means that you can send a second and third shots, unless you actively release this program."

The boy nodded slowly, then frowned quickly.

It's hard to draw just one, let alone all four programs in one instant.

It's unbelievable how Yoo Zhen and Su Meng did it.

The boy looked at the four circles on the ground glowing blue and opened his mouth wide.

Su Meng caught his expression and said, "Wen Cheng, although I want to talk about it tomorrow, but since we started, let's continue."

Wen Cheng exhaled a long breath and clenched his fists.

"Hmm! Of course!" He looked at Su Meng and nodded vigorously.
