Looking at it right and looking at it backwards, Yuan Tian didn't see any clues for a while. Forget about it for now, there are still so many paper artillery pieces to make, there is no time to hesitate.

What we want to make today is not the paper cannon like before, but the paper cannon of the chain rune type. The space between the spirit patterns was enlarged proportionally, and Yuan Tian simply didn't do anything, and directly infiltrated the four purple fire talismans in between.

The four paper cannons, not only the number of runes is four times that of the previous one, but the power of the cannon fire has increased several times. The attack power of the four-company paper cannon has surpassed that of ordinary junior monks in the Gathering Period.

In one-on-one combat, the paper cannon is not as flexible as it is and has the chance of being injured by mistake, so it is not as useful as a junior monk in the Gathering Period. But in a large-scale battle like a group attack of demon beasts, it can play a role far beyond that of ordinary junior cultivators in the Gathering Spirit Period.

What demon beasts are best at is winning in numbers, no matter how high a monk's ability is, his spiritual power is limited. Tens of thousands of demon beasts just stood there and didn't move. Even if they are soft, they may not be able to kill them all, not to mention that they will attack without killing.

The biggest feature of the paper cannon made by Yuantian is that it has a large attack range, and the purple fire burns for a long time, so it will stick to the demon beast and continue to burn for a while.

To make four paper cannons, you must first make four purple fire talismans. Yuan Tian once made four flame talismans, and also made two purple fire talismans. As for the four-in-a-row paper fire talisman, it hasn't been tried yet.

The power of the second paper fire talisman is already great enough, and you can't dodge it by yourself at close range. If it weren't for the purpose of embedding in the paper cannon, Yuan Tian wouldn't have planned to create four purple fire talismans alone. Even a weapon that kills oneself is not a good weapon no matter how powerful it is.

It's not the same when embedded in a paper cannon, it mainly kills long-range targets and has a long attack range. The use of this weapon is generally installed on the city wall and roof. Or it's inside the protective shield and bombards the perimeter. It is not high in the realm of bombardment, but there are a huge number of demon beasts, which is very suitable.

The first and second purple fire runes were skillfully stamped on the medium-grade rune paper. When it came to the third purple fire rune, Yuan Tian hesitated slightly.

Today's mental state is not very good, and he is afraid that something will go wrong. What can play a role in refreshing the mind? I knew that Lu Dao should buy some awakening pills and prepare. During this time, I have learned to fight against sword intent, and I wake up in the morning with a radiant spirit, so I ignore this matter.

If you're still dizzy in the morning, you'll be ready to do something.

Preparing things? Yuan Tian suddenly remembered, when he bought a hairpin made of Luohe stone and gave it to Senior Sister Xuanyuan, he also bought a mirror from a vendor. When I was dizzy and nervous, I relied on this mirror to refresh myself. Recently, because I couldn't use it, I threw it in the corner of the bag.

He took out the Luohe mirror from the Qiankun bag and pasted it directly on the door of his head. Qinghe's coolness is like a pair of gentle little hands, gently soothing Yuantian's divine sense.

Phew! Yuan Tianpan sat on the jade bed and exhaled a long breath. My head is finally less heavy, and my attention is no longer distracted.

Putting away the two purple fire talismans he had just made, Yuan Tian re-spread out a blank piece of paper, not in a hurry to make four purple fire talismans, but to make a four-equal Tianzi grid on the white paper, and then cover four runes on the white paper of the Tianzi grid to see if there are any deviations and overlaps.

Just now, my brain was purely confused, and I wanted to make a four-link spirit rune without seeing it, and it wasn't made at the door. If something happens, it's too late to throw it out.

Fortunately, when I wanted to print the third rune, I stopped it in time, so it didn't cause a catastrophe. After checking it several times with some blank paper, I felt that there was really no problem. Yuan Tian came to the door, spread out a piece of medium-grade rune paper, and began to print purple fire runes on it.

With the practice on the white paper, there was no obstacle on the medium-grade rune paper, and he covered four purple fire runes in one go, and then began to pour wood attribute spiritual power. At this time, the auxiliary of the cake face futon is naturally indispensable, and I hope it will not drop the chain at this time.

Purple light slowly shone up, illuminating the entire mysterious hut purple. Then it quickly converged, and a four-in-a-row purple fire talisman was declared successful. Fortunately, the cake face futon, there is nothing wrong with this. If he couldn't hold back when he was infusing the purple fire rune with spiritual power, Yuan Tian would have no choice but to throw the rune out of the rune. You can't let it explode in the house.

Offensive runes, especially fire-type attack runes, are very unstable. Not only in the process of drawing symbols, but mistakes may occur and explosions may occur. Even if the rune is not drawn wrong, if the spiritual power injected is too full, the power of the explosion is only a lot bigger.

After what happened last time, Gentian was not very at ease with the cake face futon. But if you want to make a paper cannon, you need to pour a lot of spiritual power, and you can't complete the job without a cake face futon.

I don't want to think so much, so many people are waiting for the chain paper cannon, if you can't contain the spiritual power, it's a big deal to throw it out, anyway, this room is absolutely safe.

Yuan Tian chose a large piece of medium-grade rune paper and began to draw spirit patterns on it. The spirit patterns drawn this time are different from the previous ones, the lines have become thicker and shorter, and the space between the spirit patterns has become larger. The size of this new void is just enough to seal the next four purple fire runes.

Drawing the spirit pattern will not cause an explosion and is not life-threatening. However, the accuracy of the spirit pattern directly affects the embedding of the rune. If the space is small, the runes will not be able to be put down. If the space between the spirit patterns is too large, there will be a situation where the spiritual power cannot be connected. Even if the size of the empty space is just right, but there must be a spirit pattern drawn incorrectly, it will directly affect the use of the entire paper cannon.

This is definitely a meticulous work that requires a high degree of mental concentration. The fingers and wrists should be flexible enough, and the arms should be stable enough not to shake around. A slight flicker may cause a spirit pattern to be misdrawn, or the drawing is long or short. As long as you make a mistake, the spirit pattern of the paper cannon at the main entrance will have to be redrawn.

Yuan Tian is worthy of being a master of imitation, and the regularity of the spirit pattern drawn now looks basically the same as the regularity of the spirit pattern in the book of the Evil Immortal Venerable. It's just like copying it down, his method of two hundred and fifty or six small grids, and studying the spirit patterns evenly apart, has the same effect as direct copying.

It didn't take long for the spirit pattern to finish, and Yuan Tian picked up the rune paper and checked it. He took out the book again and compared it. There should be no problem, and you can start printing purple fire runes.
