After rummaging in the Qiankun bag for a long time, Tang Chen took out a stack of rune paper, a wolf pen and a cinnabar box.

Qianfumen is famous for its rune seals, and making runes is a compulsory course for Qianfumen disciples.

Master Tang Chen is a master of refining, not famous for Fu Seal, but the formation is a link that cannot be bypassed by refining weapons, and it is indispensable, under the teaching of the master, Tang Chen's understanding of the formation method is far stronger than that of ordinary Thousand Fu Sect disciples. Backed by the formation attainment, it is more handy when making talisman seals.

If you want to improve the efficiency of spiritual food, you have to find a way to consume the excess spiritual power in your body.

After thinking about it, Tang Chen decided to try his hand at making a talisman seal.

If a specific formation is carved into the corresponding medium (usually rune paper) and injected with spiritual power, the rune paper will have the corresponding function, which is the rune seal. There is no difference between the formation on the rune seal and the formation on the embryo, but the carrier and the way of expression are different, relatively speaking, the dependence on the rune seal is more pure. The function of the rune depends on the type of formation, and the power of the rune depends on the material of the rune paper and how much spiritual power is infused.

The talisman requires spiritual power to activate, and it will continue to exert its effect until the spiritual power contained in the talisman is exhausted, which is very convenient to use. What's even more valuable is that when using the talisman, there is basically no additional consumption of the monk's spiritual power, and almost every monk will have a few in his bag in case of emergency.

There are also drawbacks to the runes.

Even if the sigil is not activated after it is made, the spiritual power sealed in the sigil will slowly drain away.

As a result, the power of the sigil decreases over time.

Under the same conditions, the high-level talisman maker has more spiritual power injected into the rune paper, and the high-level talisman maker mostly makes medium- and high-level talisman seals, and the materials used are better, and the rune seals can be kept for a longer time. Low-level talisman makers do not have these conveniences, and most of the runes they make are short-term consumables, and they usually have a strong plan to make runes.

Tang Chen was no stranger to Fu Seal.

He adjusted the cinnabar, and the wolf took the cinnabar ink in it, and then quickly landed on the rune paper.

The pen walked the dragon and snake, and the bright cinnabar ink quickly extended on the rune paper, and lines appeared on the rune paper, and at the same time, the spiritual power also seeped into the rune paper along the tip of the pen. Making the talisman seal needs to be done in one go, once it starts, it can't be stopped, Tang Chen's expression is very serious, but the hand holding the wolf is always steady, he carefully controls the rhythm of the pen movement and the spiritual power input rate, and evenly injects the spiritual power into the formation line.

After a while, a sigil was completed.

Tang Chen didn't care about checking the effect of the talisman, he immediately meditated cross-legged and closed his eyes, checking the changes in the spiritual power in his body, and after a while, he opened his eyes with a satisfied look on his face. Picking up the talisman seal that had been drawn before, gently blowing away the cinnabar that had not completely dried up, and examining it carefully, Tang Chen's smug color became even stronger.

The situation now is somewhat similar to when I was trapped in the Desperate Valley, I have eaten a lot of spiritual food and have plenty of spiritual energy in my body. Having the experience of refining rattan ropes in the Absolute Valley, Tang Chen knew the benefits of using up his spiritual power, depleting his spiritual power would put him in a state of temporary prostration, producing uncomfortable reactions such as dizziness, chest tightness, tinnitus, and dizziness, which was uncomfortable and abnormal, but the improvement of cultivation was obviously faster than following a step-by-step approach.

The first layer of the "Gluttonous Sutra" greatly increased the aura absorption efficiency when he ate the spiritual food, and the upper limit of the first layer of absorption was thirty percent, which would make his cultivation improve by leaps and bounds, but after all, there were still seventy percent of the aura that could not be absorbed. The aura that could not be absorbed would slowly escape from the pores and acupoints of the whole body and return to heaven and earth, which was undoubtedly a serious waste in Tang Chen's opinion. By consuming spiritual power through talisman making, and then meditating and pranayama to recover, you can not only use the aura that you can't absorb, but also get some more talismans.

What he had just drawn was a steel shield that increased defense and reduced damage to the body.

The Steel Shield Talisman was a common talisman paper, but what satisfied Tang Chen was its grade.

Most of the steel shield talismans on the market are first-grade low-level, with little practical value, and the price is about five first-grade spirit stones. Tang Chen's comprehension of the formation method surpassed that of his fellow brothers, but his previous cultivation was limited, and the steel shield talisman he produced was at most a mid-level one-grade, and the steel shield talisman he had just made had reached the first-grade upper level!

Put it on the market, it can sell twenty first-grade spirit stones.

Twenty first-grade spirit stones!

The grade of the steel shield talisman is so good, although it is related to the recent improvement of Tang Chen's cultivation, but the most fundamental reason is that Tang Chen deliberately increased the input of spiritual power when making the talisman seal.

With the same material, the power of the sigil mainly depends on the amount of spiritual power injected.

Due to the slow passage of spiritual power in the rune seal, the price of low-level rune seals on the market is not high, and injecting too much spiritual power will not significantly increase the value of the rune seal, but will require more time to recover the consumption of their own spiritual power, which is not cost-effective in terms of cost performance, which leads to the relatively cautious injection of spiritual power when low-level talisman makers make talismans.

Tang Chen's situation was different.

The problem he is facing now is that there is a surplus of spiritual power in his body, and he needs to consume spiritual power to improve the efficiency of spiritual energy utilization. In the past, when he made a steel shield talisman, he injected one-fifth of his spiritual power to reach the standard, but in recent months, his cultivation has been continuously improved, and the spiritual power required to make the steel shield talisman is naturally less.

"The first grade is still a grade after all, if you can make a second-grade rune seal, even if it is only a second-grade lower rank, the value is at least eighty first-grade spirit stones, however, the second-grade rune seal usually needs to be cultivated during the foundation building period to be made..."

Tang Chen is currently refining qi at the seventh layer, after cultivating the "Gluttonous Sutra", the cultivation speed is different from ordinary people, and the foundation building seems to be not far away, but Tang Chen does not dare to be too optimistic. "Gluttonous Sutra" uses food to make up for the sky, but spiritual food ingredients have never been cheap, Tang Chen is not sure how long the happy days of fake public and private affairs can last, the safest way is to have the ability to get enough ingredients.

Of course, the easiest way to get the ingredients is to buy them, which requires spirit stones.

Tang Chen's sense of urgency towards the spirit stone suddenly became stronger, and the second-grade rune seal could obviously bring better benefits.

"Half of the spiritual power makes a first-grade upper rank, if you inject all the spiritual power, can you refine the second-grade rune seal?"

Tang Chen decided to give it a try!

He was in a state of settling again.

The spiritual energy wandering in the body was sucked into the meridians and acupoints, these spiritual powers came from spiritual food, and they were mild in nature, so they didn't need to spend a lot of time refining, and the spiritual power consumed in Tang Chen's body was rapidly replenishing.

After returning to the best condition, Tang Chen grabbed the wolf hair, and the wolf hair fell on the rune paper, leaving a touch of red.

The wolf's pen was like a dragon, the cinnabar ink power penetrated the back of the paper, and the spiritual power in Tang Chen's body also gushed out, until the wolf had finished drawing the last stroke.

"Smack", the wolf put it back on the pen holder of the cinnabar box.

Tang Chen's face was as pale as paper, he held his head in his hands and let out a groan.

The loss of all his spiritual power made him feel empty in his body, and he wanted to lie on the ground, but he quickly sat down and entered a state of concentration. After relieving his strength, he couldn't wait to grab the rune paper.

"Second grade!"
