The sturdy charm on the hull of the ship is naturally to make the hull strong, otherwise the soft paper would not be able to carry the heavy load. The defensive charm is where the paper boat is different from the previous fan.

With the Defensive Talisman, this shuttle can directly raise its defensive shield, which can not only resist attacks, but also protect it from wind and rain.

But unlike Fu Yun's eighty-one layer of defensive horse coats, the defense system of this shuttle boat is not closely connected, but according to certain laws, it can be activated one by one.

The advantage of this is that a separate shield can be activated in normal times to protect against the wind and rain.

When attacked, you can activate the other defense shields one by one to improve your defense ability at once.

There are many advantages to this design, but there are also disadvantages.

If you are attacked by a powerful attack that goes beyond one or even two layers of defense, you are likely to be directly breached before the next shield is raised.

The most subtle thing about the rune paper ship is also the connection between the wind charm and the sturdy charm.

When the aura is infused, the hull of the ship becomes very hard when the Sturdy Charm is activated, and the Wind Charm is also activated, allowing it to move at any time.

For this key point, Fu Yun recorded it carefully, for fear that there would be a mistake.

What is drawn on the drawing is a miniature version of the shuttle diagram, which is completely in proportion.

Medium-grade defensive runes, medium-grade solid runes, and medium-grade swift runes, these three runes are not yet known to Fu Yun. But it doesn't matter, you just need to imitate it.

Since you want to imitate, of course, you must first spread a blank sheet of paper and copy it.

Fu Yun first imitated the size of the medium-grade sturdy talisman, made a square frame, and then drew horizontal and vertical lines, divided into sixteen uniform grids. Then along the outer box, cut out the appropriate size of white paper.

After all, the Sturdy Charm is not an offensive rune, so there are not so many instability.

After dozens of copying exercises, Fu Yun felt almost the same.

If you draw intermediate characters according to the standard requirements, it is naturally not easy.

And Fu Yun has only practiced a shape now, and he will soon imitate it.

The next step is to officially draw the talisman on the intermediate rune paper, and if you want to verify whether it is correct, you have to inject aura.

Intermediate spirit runes, a minimum of six levels of aura refining are required to take effect.

However, if you want to achieve the best effect, you need to be at the level of Qi Refining Ninefold.

Although Fu Yun was a cultivator in the middle stage of Qi Refining Eightfold at the moment, because he had cultivated the Xiao Zhou Tian Operation Method and opened up the Baihui Acupoint, his own spiritual energy was not weaker than that of an ordinary Qi Refining Ninefold cultivator, which was enough.

Of course, he wouldn't be stupid enough to keep injecting such a large amount of aura when he was drawing talismans. Therefore, it is too much consumption for the body, and it is not easy to grasp the uniformity, and the failure rate is too high.

To draw an intermediate spirit rune, you need an intermediate rune pen, which is the one given by Fu Yun when he was in Bailing Pavilion.

Of course, he already knew that the shopkeeper was named Zhou Ning, and his figure would change on his own.

The hair of this talisman is made from the tail of a silver wolf. The silver wolf is a third-level spirit beast, and if it does not have a cultivation above the spirit gathering period, it is impossible to kill.

Fu Yun tried it, and it was quite easy to use, it seemed that Zhou Ning, who would get fat and thin, was very generous and gave such a good talisman pen.

He controlled the output of the aura, and the height of the sixfold qi refining was just enough to draw an intermediate spirit rune, and he was reluctant to use it at all.

There is no problem with starting the pen, you can feel the aura input, and the strokes are quite smooth. If you go down with one stroke, you will be successful.

Suddenly, Fu Yun keenly felt that there was a trace of inconspicuous fluctuations.

Not good!

He held a pen in his right hand and threw a talisman in his left hand as the man flashed to the other side.

This time he was drawing talismans in the courtyard, and the surrounding space was relatively large, and the talismans were thrown farther.

Burst!

I didn't imagine the explosion of the mountain collapse and the earth, and the failed mid-level sturdy talisman just spontaneously ignited without wind, and then quickly burned out, turning into a small pile of black ash and falling to the ground.

Fu Yun patted his chest.

He had thought that the intermediate spirit runes were even non-offensive spirit runes. Once the manufacturing fails, the power of self-destruction should not be small.

Unexpectedly, the mid-level sturdy talisman self-destructed, barely having any power. Even if it was destroyed on the table, at most it would ignite some other papers, and it wouldn't even hurt the table.

It wasn't so dangerous, and now he was much more relieved.

Pick up an intermediate rune paper again, spread it flat on the table, continue to shrug your shoulders and hold your wrist with a pen, and draw seriously. There is no problem with lifting the pen, and the aura input is also very stable, and there is no obstacle to going down one by one.

When it came to the place where he was about to put away his pen, Fu Yun was extra careful, he made a mistake here last time.

When I practiced on a blank sheet of paper before, I didn't feel any obstacles here, so I still followed the same method. But the problem just now is here, and it shouldn't be a problem with aura input.

With his current cultivation of the eightfold of qi refining, the strength of the aura in the early stage of controlling the sixfold of qi refining is still very stable, so the problem lies in the pen.

As Fu Yun carefully changed the stroke order, then walked down the stroke, and then turned around to finish, it was finally done.

An intermediate-level sturdy talisman was made by Fu Yun like this.

From learning to copy, to successfully making talismans, it took less than an hour.

If Zhou Ning knew about this, he would definitely have to sigh again.

In fact, Fu Yun's genius is not how talented he is in talisman making, but that his mind is flexible enough and he knows how to use his own shortcuts, as long as he has the right sample, everything below will fall into place.

The next step is to engrave the seal. Intermediate runes are naturally carved with intermediate spirit stones, defense talismans are better with earth attributes, and solid talismans are better with wood attributes.

Fu Yun found a flat and smooth wood attribute intermediate spirit stone and wiped it clean.

Engraving is a meticulous job, even if the strength is great, if the hand is not dexterous enough, it will be in vain.

Don't look at Fu Yun's strength, this slender ten fingers are more flexible than a small snake.

A pair of black and white eyes stared closely at every part of the knife.

After carving for a while, I felt that the knife was a little dull.

I didn't feel it when I carved the spirit stone before, but now I feel that the resistance is a bit big when I carve the spirit stone.

Fortunately, this is a wood attribute spirit stone, and the texture is relatively soft. If this is replaced with a metal spirit stone, I am afraid that it will not be moved. After carving a few strokes, Fu Yun stopped, a little uneasy.

If you engrave it like this, the lines may not be smooth enough, which will affect the quality of the final seal.

In order to ensure the smoothness of the carving, he felt that he still needed to go to the sect exchange office and buy a better carving knife.

As for this medium-grade spirit stone, it has only been carved a few strokes, and it should not affect its use, just buy something and spend it another day. Fu Yun put the carving knife away, and was about to pack up his things and go out, when he suddenly remembered something, the black needle he touched on the second floor of the Tower of Babel.

This little thing is as easy to pierce into bluestone as it is to pierce tofu, will it work well when used to engrave seals?
