Inscription is different from ordinary painting, painting can start from any place and end at any place, but inscription magic pattern is absolutely not. Each pattern has its own unique start and end point, and only when the start is engraved and the end point is completed, will the magic pattern come into play.

After finding the starting and ending points, Zhang Ning carefully opened one of the three bottles of liquid, and carefully reached into the bottle with the tip of the light pen, stained it with the blue liquid.

These blue liquids are the most common alchemy potions on the market, and they only have the most basic effect of exerting the effect of alchemy patterns. As far as Zhang Ning knew, there was a particularly expensive alchemy potion on the market, and the alchemy pattern engraved by using that alchemy liquid could not only exert 500% of the effect of the magic pattern, but also add other additional effects to the magic pattern.

As for the light pen in Zhang Ning's hand, it is a special pen engraved with magic patterns.

Because the inscription of the alchemy magic pattern requires the use of spiritual power to evenly distribute the alchemy potion to each node of the magic pattern, and people's accuracy in controlling the spiritual power is not enough, so the light pen, a tool for evenly distributing spiritual power, came into being.

The light pen is divided into three categories, the first type is the ordinary light pen, this kind of light pen can only evenly distribute the mental power; the second type is the amplification light pen, this kind of light pen can not only evenly distribute the mental power, but also can improve the user's mental power within the specified time; the third type is the special class, this kind of light pen engraved magic pattern than the general light pen engraved magic pattern, will have more special functions.

With Zhang Ning's financial resources, the light pen in his hand is naturally the most ordinary light pen. Although he knew that a good light pen could help him improve his mental power and improve the success rate of inscription magic patterns, Zhang Ning had no choice but to take out all his belongings and only afford ordinary light pens, so he had to give up.

Call!

Exhaling deeply, after recalling the magic pattern again in his mind, and making sure that he already knew all the inscription structures of the magic pattern in his heart, Zhang Ning suddenly opened his closed eyes, and after instilling spiritual power into the light pen, he slowly pointed out the starting point of the spirit gathering magic pattern on his left arm.

Hurt!

This is the only feeling that Zhang Ning feels when the tip of the light pen touches the skin of his left hand.

It was as if someone was holding an awl and stabbing him in the left hand!

"Damn!"

Because of this unexpected pain, Zhang Ning couldn't help but snort, and the light pen in his hand was also thrown aside. The starting point of the glowing left hand was also dimmed by the departure of the tip of the light pen.

Because I shook off the light pen, the pain in my hand disappeared, leaving only a slightly hot burning sensation. Moving his left hand in front of his eyes, Zhang Ning was surprised to find that a white dot appeared in the place where the dot was drawn, which looked like it had been burned.

"Your uncle!

While constantly shaking his right hand, Zhang Ning picked up the light pen.

Theoretically, before the inscription of the magic pattern is successful, the magic pattern will not work at all, why did I feel the pain of being pricked by a needle just now? Is it a problem of mental power? It is not right, if the mental power is insufficient, it will only lead to the failure of the inscription, and there will be no other sequelae.

Thinking back on the knowledge in the books, Zhang Ning couldn't help but feel confused.

In fact, the reason why Zhang Ning felt pain was very simple, it was because the alchemy potion played the role of "carving".

The reason why the alchemy potion is called the alchemy potion is because the alchemy potion has the function of alchemy, and the most basic function of alchemy is to engrave! The alchemy potion alone will not cause harm to the human body, but if it is through the spiritual power contained in the light pen, then the alchemy potion will have the basic effect of "carving".

As mentioned before, the alchemy pattern is like a circuit board from the previous life. The densely packed circuits on the circuit board must be soldered, otherwise it is easy to make the circuit fail, and the same is true for the alchemy pattern. The reason why the alchemy pattern only needs to be painted and does not need to be engraved is precisely because the alchemy potion itself has the function of "carving".

This is why the act of drawing alchemy patterns is called "inscriptions".

If the alchemy pattern is engraved on the body, if it is placed in Zhang Ning's previous life, it is to inlay dense lines on the body - and these lines are still conductive!

That is to say, in this life, painting magic patterns on the body actually means one word - death!

Because this truth is well known to everyone, no matter what books are written after that, it does not specifically mention this point. Helplessly, Zhang Ning was reborn into this world. Although he learned the knowledge of junior high school and has a junior high school diploma, he does not know the most basic things, even five or six-year-old children know.

It is precisely because of this that Zhang Ning would have such a rebellious idea as inscribed the alchemy demon pattern on his body - normal people would never want to put a circuit board on their body.

"Is it because there aren't enough alchemy potions?"

After thinking for a long time, Zhang Ning thought of the possible reasons for the failure of the inscription.

"The book only mentions the drawing method of the Gathering Spirit Pattern and the alchemy potion needed to make the Gathering Spirit Pattern, but it does not mention the dosage of the alchemy potion, could it be that there is a problem with the dosage of the potion?"

Since there is no problem with the magic pattern itself, there is no problem with the potion, there is no problem with the light pen, and even the mental power that is most likely to have a problem is not a problem, then the problem must be the dosage of the potion.

With this in mind, Zhang Ning quickly added all the remaining two bottles of alchemy potion to the light pen.

"Damn, this is all Lao Tzu's belongings. Looking at the light pen head flowing with a strange light, Zhang Ning said viciously. "This time we must succeed for Lao Tzu!"

Cheering himself up and instilling all his spiritual power into the light pen, Zhang Ning gritted his teeth and pointed the tip of the pen on his left arm again.

Pain!

Pain deep into the bone marrow!

The same situation happened again, just as the tip of the pen touched his arm, a burning pain flowed out of Zhang Ning's left hand, and it flowed all over Zhang Ning's body in an instant.

Subconsciously wanted to throw the light pen aside, but just as the tip of the light pen was about to leave the skin, Zhang Ning gritted his teeth and then drew a magic pattern on his arm.

"You, you're yes, oh the vegetable cloth is fat and drunk to scoop water (your grandfather's, I won't waste the last potion). With his love for potions, or money to be precise, Zhang Ning actually endured the pain that hurt into his bone marrow.

Under the influence of strong willpower, Zhang Ning put all his essence and spirit on the engraved spirit gathering demon pattern.

The light pen in the hand gently brushed the skin, and at the beginning of the stroke, pulled a curved line with a pale blue light, and when the line was drawn to the left side, the tip of the pen was lightly hooked, and the blade-like side hook drew the arc to the other side......

Gradually, a complicated and mysterious magic pattern gradually became clear.

However, the good times did not last long, although willpower is important, but once a certain limit is exceeded, even if there is strong willpower, it is useless, plus it takes a lot of mental power to engrave the magic pattern, just when Zhang Ning drew the magic pattern to two-thirds, and was about to finish the magic pattern, a more powerful pain rushed towards Zhang Ning.

"I ......" couldn't be said by the words, Zhang Ning's eyes rolled, and he lost consciousness in an instant, and the spiritual power he was instilling disappeared in an instant.
