After killing Meng Yuan, Ye Tian kept his door closed for the past two days, carefully comprehending and recalling the details and experience of the battle with Meng Yuan.

"Finally broke through..."

Slowly exhaling a breath of turbidity, hearing a crisp sound coming from the dantian, Ye Tian showed a smile.

"With my current strength, I should be able to beat ten Tang Jian. ”

Feeling that the Wu Yuan circulating in his body was much more surging than before, Ye Tian clenched his fists and said with some confidence, when he was a two-star martial artist, he and Tang Jian could only find a flaw before he could make a move, and now he can definitely easily defeat the enemy with one move.

"Ding! Congratulations to the host 'Ye Tian' for advancing and getting a chance to win a primary lottery, please ask if the host will draw the lottery immediately. ”

"Smoke it. "Although there is generally nothing good in the junior lottery, it is better than giving nothing.

"A junior draw is underway... Ding!Congratulations to the host for obtaining: Rune Paper *10, with a feather engraving pen, and opening the exchange function of Rune Paper, which costs 100 exchange points to exchange for a rune paper!"

Rune paper is a necessity for carving spirit runes, and Ye Tian once asked Wang Shui, the manager of the auction house, if there was rune paper.

As a result, Wang Shui didn't know what the rune paper was, and Ye Tian was also speechless, thinking that there was really no rune master in this world.

The feather carving pen is also a necessity for carving spirit runes, although the appearance is similar to a feather, but it has two magical functions.

First, it can absorb liquids, so that users do not need to frequently dip in ink to delay time when carving spirit runes.

The second is that it can inject spiritual power, and when the user is carving the spirit rune, it will be more smooth.

"I actually opened the exchange, Erbo, what's going on, why can't the things I drew before be exchanged?" Ye Tian was a little puzzled, he had also drawn a lot of pills and props before, but he didn't activate the exchange function.

"Ding! Remind the host, each lottery of items, there is a certain chance that can be opened for exchange, the current probability is 0.5%, with the upgrade of the system, the probability will slowly increase. ”

"Oh, how can the system be upgraded?" Thinking back to what the system said before, every time the system is upgraded, it will bring new features, and Ye Tian naturally wants to know how to upgrade.

When the host encounters a crisis for the first time, the system will perform an upgrade, and then the host needs to improve its own realm if it wants to upgrade the system. ”

"Every time the host improves a major realm, the system can be upgraded once, such as the host breaking through martial arts cultivation to become a martial artist. ”

Ye Tian nodded, and after coming back to his senses, he was excited in his heart, he had always wanted to try to depict the spirit rune, but he suffered from the lack of rune paper, this time he not only drew 10 pieces, but also opened the exchange function.

Although it takes 100 exchange points to exchange a piece of paper, Ye Tian didn't feel expensive, after all, there is no such thing as rune paper in this world, and it is fortunate to be able to exchange it.

As soon as his mind moved, a feather engraving pen appeared in his hand along with a piece of rune paper.

"Is this the rune paper..."

The color of the rune paper is yellowish, similar to some ancient paper, except that it is a little cold to the hand, Ye Tian really can't see anything extraordinary.

"Forget it, let's study the Spirit Rune Heart Sutra first. ”

Opening the Spirit Rune Heart Sutra in his mind, looking at the strange words on it that looked like a formation script, Ye Tian began to think about it carefully.

These strange and complex text symbols, known as runes, are also the root of the magic of spirit runes.

"The runes that depict the spirit runes seem to be similar to the runes of the formation. ”

When Ye Tian had just obtained the Spirit Rune Heart Sutra, he only glanced at it a few times and didn't study it much, but now he compared the runes on it with the inscriptions of the formation, and was surprised to find that although the runes and the inscriptions were equally complicated, they had rules to find.

"With my spiritual power, I should be able to carve a first-grade spirit talisman. ”

The Spirit Gathering Rune is a relatively practical spirit rune that can increase the user's cultivation speed, and after using it, the cultivation speed can be doubled in a month.

However, with Ye Tian's current spiritual power, he can only depict a first-grade spirit gathering talisman, this kind of spirit gathering talisman is only effective for martial cultivation, once the user exceeds this realm, he can also speed up his cultivation, but it does not have such a high effect.

At this moment, Ye Tian had already memorized the runes that carved the spirit gathering runes, according to the spirit rune Heart Sutra, the spirit runes only needed rune paper and blood, and the demon blood was generally the mainstay.

"The demon blood collected in the Rain and Fog Forest some time ago has finally come in handy. Ye Tian smiled, and immediately took out a jade bottle filled with second-order demon blood from the storage ring.

Unplugging the cork from the mouth of the bottle, Ye Tian directly inserted the feather engraving pen into it.

In a few breaths, the feather carving pen actually absorbed all the blood in a bottle, and there was no change from the appearance.

"What an evil thing... Maybe it can be used as a weapon in the future. Looking at the empty jade bottle at this time, Ye Tian secretly smacked his tongue, lifted the feather engraving pen and slowly wrote a complex text symbol on the rune paper.

Although the surface of the rune paper is relatively smooth, the blood is absorbed by it immediately after touching the rune paper, as if it has dried immediately.

"Women's treasure!" Seeing this scene, Ye Tian was suddenly a little surprised, he didn't expect that this seemingly ordinary rune paper was so magical.

"If you know how to make it, you can put it on the earth and it will benefit mankind. Ye Tian shook his head with a smile and continued to start carving runes.

When carving a rune, each rune is extremely important, and even a single stroke of the wrong stroke will make the entire rune ineffective.

Ye Tian's action of carving the runes was a little slow, but due to the magical function of the feather carving pen, there were no mistakes.

At this time, Ye Tian's whole person seemed to have fallen into a wonderful situation, forgetting about things and me.

Suddenly, a crack appeared under the rune paper, making Ye Tian frown.

It is recorded in the Heart Sutra of the Spirit Rune that when there is a crack in the rune paper, it means that the spirit rune has failed to be carved, and the rune paper will be scrapped and cannot be used.

Ye Tian didn't control his mental power well, and when he just sketched a rune, he used too much force, so that the rune power was released, directly destroying the rune paper.

"It seems that it is much more difficult to carve spirit runes than to arrange formations. ”

Ye Tian shook his head helplessly, he succeeded in arranging the demon beast spirit array for the first time, and he was also engrossed, and he only completed a third of the carving spirit runes, and then failed.

After destroying the three runes, Ye Tian finally became proficient and carved out the last complex rune.

Seeing the red light flashing on the rune paper, Ye Tian put away his fingers and wiped a handful of sweat on his head, secretly carving the spirit rune was too consuming spiritual power.

"I don't know which powerful person created the spirit rune, it's so mysterious. ”

These seemingly complex and awkward runes, after being carved, turned out to be particularly symmetrical and the same as the formation.

Spirit runes and formations have their own strengths and weaknesses, formations cannot be moved, but they can be used for a long time, and although spirit runes can be carried around, each spirit rune can only be used once.

Once the spirit rune is carved, the user only needs to inject his own martial arts or spiritual power, and then say "Pro!", and the spirit rune can be activated.

Ye Tian looked at his masterpiece carefully, and said with a smile: "Let's try the effect next..."
