When the big head handed over the evil spirit, a soul talisman was almost finished, and only the "soul" on the talisman was missing.

Picking up this talisman, Jiang Feng slapped it towards the evil spirit.

"Smack"

This talisman will collect the evil spirits, and Jiang Feng's experiment seems to be close to success!

However, a smile appeared on Jiang Feng's face, and he suddenly changed color, throwing out the soul talisman shaking hand.

"Oops, not good!"

Before Jiang Feng's voice landed, the soul talisman shook violently in mid-air, and this talisman seemed to be unable to restrain the evil spirit, and finally shattered, and the talisman paper and the evil spirit were turned into powder and dissipated in the air.

The experiment failed.

Jiang Feng stared at the place where the soul talisman exploded, stunned.

"Master......" The big head wanted to persuade Jiang Feng.

"Big head, catch me another evil spirit!" Jiang Feng came back to his senses and said firmly.

"Ah...... Good!"

Soon, the big head grabbed another evil spirit and ran back quickly. And Jiang Feng had already finished making a newly carved soul talisman, just waiting to ban the evil spirits.

Jiang Feng slapped the evil spirit on the evil spirit again with the talisman, and put the evil spirit away with the soul talisman.

The second time was obviously much more ideal than the first, and a subtle fluctuation of spiritual power rippled on the surface of the soul rune, and then gradually stabilized.

The big head shook his head and leaned forward and asked, "Master, has the production been successful?"

Jiang Feng's expression was all focused on the soul talisman at the moment, and he didn't care about the big head at all.

It was only half a minute later, and suddenly Jiang Feng shook his hand and threw out the soul talisman. As soon as the big head wanted to fly out to catch the soul talisman, he heard Jiang Feng say, "Don't go!"

The big head stopped abruptly.

The second soul rune suffered the same fate, blasting into pieces in the air and dissipating into powder.

"What went wrong?" Jiang Feng looked at the place where the soul rune dissipated, and fell into deep thought.

The big head could only stand aside obediently, not daring to disturb Jiang Feng's thoughts.

"Big head!"

"Yes, master......" This time Jiang Feng opened his mouth, and the big head immediately flew out without hesitation, of course he knew what the master told him to do.

Jiang Feng had two experiences and lessons, and the third time he was quite cautious and preoccupied, not allowing the slightest mistake.

When the evil spirit was put away for the third time, Jiang Feng still frowned, yes, there was a problem again, there was a problem with the charm at all, it seemed that it couldn't seal the evil spirit in it!

Why are critters okay but evil spirits can't?

This kind of weak evil spirit does not have much ability to resist, and there is no theoretical problem in suppressing it with soul talismans.

So what's the problem?

Before, Jiang Feng thought that there were some minor problems in the control of the soul talisman, such as the little mouse and angry bird that he successfully made, there were many flaws.

It's just that Jiang Feng hasn't found out where the flaws are for the time being.

This is always confusing for Jiang Feng.

Obviously, this time the sealing of the evil spirits has infinitely amplified the previous defects of the soul talisman, which has led to the final failure of the talisman again and again.

Where are the instability factors, and what causes the instability of the soul runes?

This time, the problem was really discovered, Jiang Feng did not immediately try again, if he could not find the root cause of the failure, even if he tried ten or twenty times, I am afraid it would end in failure.

Jiang Feng sat there, thinking hard for nearly half an hour, still confused.

Later, the fruitless river breeze beckoned the big head to return to the campsite.

At this time, it was nearly ten in the middle of the night, and according to the prior agreement, Jiang Feng should go to call for them to change shifts, but Jiang Feng did not call them.

Relight the campfire and face it in a daze.

"Master, it's time for you to rest, the talisman making matter is ...... long-term," the big head persuaded.

"No, I can't figure it out, I won't rest, you don't have to worry about me, if you're tired, go back to sleep. Jiang Feng said.

The big head suddenly has two big heads, and the master doesn't rest, how can he hide and sleep. If you can't do anything else, there's nothing difficult in guarding the master.

He followed the example of Jiang Feng and began to breathe in, trying to cultivate to kill the boring time.

Not long after, Jiang Feng's expression suddenly moved, and with a touch of his hand, he took out a soul talisman that had been made long ago from the space ring.

Taking out this soul talisman, Jiang Feng focused all his attention on the soul talisman.

After continuous talisman making, Jiang Feng already had a lot of experience, and he first went to observe whether the soul talisman was flawed. But after the inspection, there was no flaw, and his talisman making technique was completed in one go, almost to the point of perfection.

"Well, the problem is really in the talisman!" Jiang Feng showed a rare smile.

Talisman making is not a simple job, the process is cumbersome, from the production of talisman paper, to the processing, configuration, synthesis of talisman materials, as well as the technique and layout of talisman making, all of which are indispensable.

Of course, the rune paper required for low-level runes is not demanding, and the more important thing is the rune material.

Symbols are generally made up of a variety of materials, and different materials are used according to the function of the symbols. Many materials of talisman materials still need to be processed, purified, and converted into what is needed.

The rune material is made into rune liquid, engraved on the rune paper, and fused with the rune paper as a whole, and the rune is considered complete.

Compared with ordinary talismans, the extra procedure for making soul talismans is to seal or suppress the soul in the talisman, and when it is driven, the soul in the soul talisman bursts out with powerful energy.

However, the main problem now is that the evil spirit cannot be completely sealed in the soul rune, and once the evil spirit is detained, there will be instability, causing the spirit rune to explode on its own.

The key question is how to make the soul talisman stable!

Generally, the talisman is divided into three parts: the talisman head, the talisman gall and the talisman foot, and Jiang Feng's soul talisman is also indispensable.

In the end, Jiang Feng stared at the position of the most critical talisman of the talisman. As the heart and soul of the soul talisman, the role of the talisman is like the human brain, irreplaceable!

Looking at Fu Dan, Jiang Feng's heart moved, he cut his finger and dripped a drop of blood on Fu Dan.

Blood quickly seeped in. Jiang Feng grabbed the talisman in his hand, and his thoughts moved again, he had already communicated with this talisman, peeking into the interior of the soul talisman, the structure was completely three-dimensional, and it was all in his grasp.

Yes, that's how it feels!

Jiang Feng finally came to his senses, and took this talisman and galloped towards the waters of Crescent Lake.

When he came to the water, Jiang Feng once again caused the evil spirits in the water, seeing these evil spirits rushing wildly, Jiang Feng did not move at all, instead of taking out the demon rain, he waited for those evil spirits to fly closer.

More than ten meters away, Jiang Feng raised his hand and knocked out this soul talisman.

This time, after the soul talisman left his hand, it emitted a dazzling light, instantly turning into the light and shadow of an angry bird, shooting towards those evil spirits.

The evil spirit suddenly panicked, but the Angry Bird was extremely fast, and in an instant it scurried into the middle of the evil spirit.

It was only at this time that Jiang Feng snorted lightly, "Burst!"

The soul talisman erupted in the midst of the evil spirits, releasing a very powerful energy mass that instantly covered a wide range!
