There are eight voids on a paper cannon, and four purple fire talismans are embedded in each void. Without injecting spiritual power, you can fire thirty-two consecutive times. Even the evil Immortal Lord here will be frightened by Yuan Tian’s bold approach.

Yuan Tian focused all his energy between the seal and the talisman paper, and there should be no error in the position of the fall. The four-consecutive purple fire talisman injects a lot of spiritual power when the fourth rune is sealed. The paper cannon is different. It is when the last purple fire rune, that is, the 32nd rune, begins to inject a lot of spiritual power.

If there is any difference between the previous runes, it will appear when the spiritual power is injected into the end, and thirty-two purple fire talismans explode together, it will be a disaster.

There is no problem with the fourth purple fire rune stamp, there is no problem with the sixteenth purple fire rune stamp, and there is no problem with the thirty-one rune stamp. Before printing the thirty-second rune, Yuan Tian stopped first.

The last purple fire rune is also the most critical rune. After this rune is printed, there is no problem injecting spiritual power, which means that most of the time has been undertaken, and the rest is the issue of the amount of spiritual power injection.

Yuan Tian shook his stiff neck and took a few deep breaths. He calmed down and checked the thirty-one runes in front. He felt that there was no problem, so he picked up the seal and prepared to print the thirty-two runes.

Success or failure is here. When the 32nd purple fire rune falls, Yuan Tian inputs a little bit of spiritual power to test it first. The spiritual power flows smoothly and there is nothing abnormal. Finally, I can rest assured.

Holding the seal tightly with his right hand and putting his left hand on his right hand, Yuan Tian began to forcefully pour spiritual power into the paper cannon. The spiritual power that the thirty-two purple fire runes can store is simply incredible.

Even with the help of a pancake face and cushion, it would be a very difficult task. Fortunately, Yuan Tian’s cultivation level now has mentioned the eleventh level of Qi training, and the spiritual power he can accommodate increases and his meridians become thicker.

The meridians are equivalent to the pipe that transports spiritual power. If the pipe is not thick enough, even if the spiritual power reserve is large, the flow speed will still be very slow. Only when the meridians are thick can the spiritual power be paid more quickly to the paper cannon.

I don’t know what kind of treasure this pancake face cushion is. It seems to contain infinite spiritual power, which is continuously transported outward without any interruption. The spiritual power enters Yuantian’s body and then goes up from the tailbone, follows the Ren and Du meridians, and then passes through the arm to the seal from the top, and finally enters the paper cannon.

The process of infusion of spiritual power by paper cannons is also a process of training itself for Yuan Tian. With the erosion of spiritual power over and over again, the meridians become stronger and the body is moistened.

Spiritual power can be continuously absorbed from the pancake face and cushions, but human physical energy is limited. With such high-intensity work, both physical strength and energy are rapidly consumed. Yuantian's body began to tremble slightly, which is a symptom of the extreme physical strength.

The sweat on the forehead slid down through his face, and Yuantian rubbed his chin on his clothes. Before the solid rune was activated, the paper cannon must not be touched.

Things like talisman paper are afraid of water. This is not a fatal weakness, but they cannot be ignored. If someone attacks with water before the paper cannon is activated, it will easily destroy it.

When the purple light converged in, the chain of paper cannons was declared successful. Yuantian held the paper cannon, without the joy he imagined.

The talisman is usually installed in the Qiankun bag and is only taken out when used. When activated, it will be thrown out directly, so there is no need to consider the issue of waterproofing. However, paper cannons are things that need to be reused and are set on the wall for a long time. If the waterproofing problem is not solved, it will always be a hidden danger.

Can you add the water-avoiding rune? Where should you be if it is added? Yuantian fell into deep thought.

Remove the position of a purple fire rune and embed the water-avoiding rune, which may lead to instability. Is it feasible to remove a solid rune? Yuan Tian thought about it carefully and was not very sure if he did this.

Since the rune attributes on the paper cannon cannot be changed, you have to find a way outside the paper cannon.

There is! Yuan Tian slapped his thigh and suddenly stood up, thinking of a note. The overall structure of the paper cannon cannot be destroyed, but additional accessories can be added.

A water-avoiding talisman is attached to the paper cannon. This water-avoiding talisman must be in an active state for a long time. A water-avoiding film is formed and it is always water-proof for the paper cannon.

This method should work, and the remaining question is how to make the waterproof membrane last longer.

The persistence of the water-avoiding membrane is inherently stronger than that of the defense cover. Even without spiritual power, it can exist for two days. Through the connection of the spiritual patterns, it is transformed into a recyclable structure, and the spiritual power is infused every once in a while, which can solve the problem of durability.

It is still a bit too troublesome to inject spiritual power every two days. Just get four four-component water-avoiding runes, and the storage capacity of sixteen runes is strong, and it will not hinder the use if you don’t inject spiritual power for a month.

The method of making water-avoiding talismans was learned from the jade slips that were interpreted by talismans. However, it is not the time to make water-avoiding talismans, making a few more paper cannons is the top priority.

After almost recovering his physical strength, Yuan Tian picked up the talisman pen and spread the talisman paper, and began to draw the spiritual patterns of the second paper cannon.

I was busy until the evening and created a total of five chain paper cannons. The drawing of spiritual patterns and the printing of runes did not take much time. The new paper cannons stored too much spiritual power, which slowed down the manufacturing speed.

If you are making ordinary paper cannons, you should be able to make seven or chain paper cannons today, five cannons are already the limit.

If he uses this to get in touch with the Fourth Elder, he will definitely be very happy. Will he increase the reward? If he gives it to the Spirit Gathering Pill, it will be too good.

After leaving the mysterious room, he put away the large light pearl. Yuantian walked out while thinking that the sect still needed to hand over three sects, and today he could only sell two chain paper cannons to Shidong.

The base plate of the early warning array did not sound, so there should be no problem in the cave. However, there is a saying that, be careful to make the ten thousand-year-old ship. When it reaches the edge of the hall, Yuan Tian still threw a two-in-one flame talisman into the cave first.

"Boom", the surging heat wave swept through most of the cave. Some of them even passed through the opening of the wall to the main hall.

There should be no problem. Yuantian leaned into the cave. He was not in a hurry to enter now. He had just been roasted by fire and the temperature in the cave was too high.

"Swoosh swish swish..." Several light green shadows flashed by.

Oops, it was ambushed! This time the monster was so treacherous that it was ambushed in the hall in advance. When Yuantian passed by the hall just now, they did not rush to take action, maybe they wanted to block the cave and then start.
Chapter completed!
