Reborn as a girl, I will live forever in the world of immortality

When I walked into the room, I saw a red fox standing on a chair, holding a brush and writing and drawing on a piece of yellow paper.

When it saw He Ling coming in, it immediately tensed up its body and used a little more strength in its claws holding the talisman pen.

He Ling naturally noticed the red fox's nervousness. She rolled her eyes and deliberately walked behind the red fox. She stood there without saying a word.

The red fox drew a few strokes, and the claws holding the talisman pen began to sweat. It swallowed its saliva. Oh my god, the oppressive feeling of the boss standing behind it was too strong.

Finally, the red fox could hardly continue painting, so he put down the talisman pen and whimpered twice to He Ling.

He Ling couldn't help but smile. He touched the red fox's head and then took out a bottle of pills as compensation.

Sitting next to it, she took out a spare talisman pen and began to draw explosive talismans. Most talismans have some similarities, not to mention that He Ling had already drawn the more difficult Golden Sword Talisman. After drawing five or six talismans, He Ling slowly got the hang of it. By the time she had drawn about the twentieth talisman, she had basically mastered the trick of the explosive talisman.

At this time, she took out the black talisman paper and cut it into small pieces. However, it was not so easy this time. She failed every time she drew a few pieces. In the end, after so many failures, He Ling also summarized the problem.

As a mid-grade yellow-level talisman, the Exploding Talisman has about twice as many strokes and spiritual power nodes as the Fireball Talisman. If He Ling wants to draw the rune on such a small talisman paper, the talisman pen in her hand is simply not enough to complete it. She needs a smaller talisman pen. Moreover, it is not easy for her to observe the details when drawing because the talisman paper is too small.

This is also one of the reasons for frequent failures. It would be best to have an object that can magnify the talisman paper in front of you.

Once you know the problem, the rest becomes much easier.

The first thing to do is to solve the problem that the talisman paper is too small. It is naturally impossible to enlarge the talisman paper, so He Ling thought of making a magnifying instrument. The principle is also very simple. Just superimpose several convex lenses on each other and the job is done.

As for how to make a convex lens, He Ling knew that sand could be melted into glass. There was a lot of sand in the cave, so he could just grab a handful of sand and melt it. He called Qing'er out to pull the bellows again. After a while, a pile of sand turned into a fiery red malt sugar shape. Then he put the melted sand into the sand used for casting. After cooling, he got a piece of green glass. If he looked closely, there were quite a few bubbles in it.

This is definitely not usable. After trying a few more times, I managed to produce a batch of good products. Although there are bubbles in it, they are much less and can be barely used.

However, the problem of the glass turning green and the low clarity arose again, and He Ling could not find any solution in a short time.

In the end, he scratched his head until it became bald, and he couldn't figure it out. He really had no other choice, so he remembered that this was a world of cultivating immortals, and there should be crystals like the glass in his previous life.

In the next two days, He Ling went to the Free Cultivator Square and the Weapon Refining Pavilion. Finally, she really discovered a spiritual mineral called Snow Crystal. It was completely transparent and much clearer than the glass in her previous life. However, this was a spiritual mineral and was expensive. In the end, He Ling reluctantly spent two thousand spirit stones and bought six pieces to take home.

This snow crystal is very peculiar. Although it looks like a piece of glass, it is actually made of the same material as iron. As long as it is not contaminated by any impurities during the smelting process, it is basically transparent. After cooling, take it out of the mold and you will get six convex lenses.

Mount the lens on a wooden stand prepared in advance, and a magnifier is ready.

After trying it out, I found that depending on the number of lenses added or subtracted, the maximum magnification was about ten times, and the minimum was three times, which fully met He Ling's needs.

Next was the issue of the talisman pen. The Equipment Refining Pavilion and the Talisman Pavilion certainly didn't sell such a small talisman pen. As for custom-made ones, He Ling did ask about it, but either others quoted a price one or two times higher than the market price, or simply refused to accept it.

He Ling didn't want to be a sucker. Generally, talismans were engraved with formations to channel spiritual power, which she certainly didn't know how to do. However, she could modify the existing ones. Now that she had some knowledge of refining equipment, she could give it a try.

This time it went very smoothly. I bought some top-quality wolf hair brushes, tied them into a thin thread, removed the original nib, inserted a special wooden stopper, and then inserted the new nib in the middle. A special talisman brush was completed. I tried it and it was basically the same as the original talisman brush.

With two professional tools, the rest of the work became much simpler. The explosive talisman was successfully drawn on the small black talisman paper in one go.

After drawing more than ten pictures, He Ling finally stopped.

I took out the previous gun barrel again. Although it was damaged, it was still fine for use in experiments.

As usual, he first implanted the talisman paper into the gun barrel and put in the iron beads. This time, He Ling specially used a piece of iron blank to make a target.

As the spiritual power was activated, the explosive talisman suddenly exploded, releasing a huge amount of pressure into the small gun barrel.

With a loud "bang", the barrel of the gun in He Ling's hand suddenly exploded, and a fireball exploded in the air, and the flames directly enveloped He Ling.

"Cough cough." He Ling coughed twice and fanned the black smoke in front of her eyes with her hands. She was already wearing a spiritual armor, and now she was in the stage of minor success in body tempering. The strength of her hands was close to that of a low-grade spiritual weapon, so she was fine.

Her face was a little dark and her hair was a little messy, but He Ling was staring at the half-exploded gun barrel in her hand at this moment, with a look of excitement on her face. She was more and more sure that her idea would work.

This time He Ling looked up some classics. She needed a metal that was hard, heat-resistant, not easy to deform, and preferably light in weight. After a while, she found a spiritual ore - iron essence.

Then He Ling went to ask about the price. When he first heard six hundred spirit stones, he thought it was normal. Later he learned that six hundred spirit stones per gram...

When she finally left the Spirit Object Pavilion, He Ling couldn't help but touch the storage bag of dry-fried spirit stones. She reluctantly bought one hundred grams. He Ling was really out of money now. There were only a few hundred spirit stones in her storage bag.

After finishing this matter, she will start thinking about how to earn spirit stones.

After returning to the cave, the process of making the gun barrel began.

After a period of smelting and casting, a small cylinder glowing white appeared in front of He Ling.

As usual, he put in the talisman and iron beads, and directed his spiritual power towards the spiritual iron embryo not far away.

A thrust suddenly came, and the next moment a muffled sound was heard. At the moment the muffled sound came out, a crisp "clang" sound was heard from the embryo not far away.

He Ling was shocked. She didn't even see how the iron ball was shot out, and the embryo had already been hit.
