The power of the detonation spirit rune was not too great, and Chen Tiansheng blasted out with a palm at will, and the palm strength formed a hemispherical arc, blocking the qi wave formed by the explosion outside.

However, the Detonation Spirit Talisman gave Chen Tiansheng an extremely strong shock.

A detonation rune is not very powerful, what if it is ten, hundred? Hundreds of detonation spirit runes were detonated at once, and I am afraid that the powerhouses of the acquired realm would not dare to resist hard.

The way of the rune seal is indeed not to be underestimated.

Of course, this has to be used appropriately to be effective, and which of the strong people in the acquired realm is not the only one who stands alone. If a martial artist of the Inner Strength Realm wants to use the Detonation Spirit Rune to challenge the Acquired Realm powerhouse, I am afraid that the Detonation Spirit Rune will be slapped to death by the Acquired Realm powerhouse before he has time to use it.

Although there are still some flaws in this Detonation Spirit Rune, its power is very extraordinary, and if this small flaw can be improved, the Detonation Spirit Rune should be regarded as something worth studying.

Although the Detonation Spirit Rune is useless against the strong people of the Acquired Realm, it can pose a great threat to the martial artists of the Inner Strength Initial Realm, and even have a certain impact on the martial artists of the Inner Strength Middle Realm.

This is something that can play a key role in the war between the two countries, after all, all the largest warriors in a country are in the internal strength realm, and it can even be said that the internal strength realm is the basic combat power of a country.

Thinking of this, Chen Tiansheng didn't understand a little, if this detonation spirit talisman was used in the army, it would definitely be a sharp weapon in its own right.

Then how can Song Wushuang be regarded as a Fu Seal Master, how can he be called a waste?

Song Wushuang looked at Chen Tiansheng with some embarrassment: "Brother Tiansheng, I still have some small problems with this low-level detonation, if this problem is solved, I won't be afraid of those guys." ”

Speaking of this, a look of excitement appeared in Song Wushuang's eyes.

"Low level, do you have any other levels of this Explosive Spirit Rune?" Chen Tiansheng was a little puzzled.

Song Wushuang said proudly: "That's natural, you must know that the way of the rune seal thousands of years ago was extremely prosperous, and no one dared to mess with a rune master, but at that time, the rune master was proficient in runes, runes, beast taming and rune cultivation, and the strength was extremely strong." ”

"But until now, there are only some sporadic records in ancient books left in the way of the runes, and this explosion spirit talisman and rune finch are still collected by me for a long time in this regard. The power of the low-level detonation rune is comparable to the full force of the martial artist of the initial realm of internal strength, the power of the mid-level detonation spirit rune can be compared to the full force of the complete internal strength, and the high-level detonation spirit rune is equivalent to the blow of the strong person of the acquired realm. ”

Chen Tiansheng was shocked, the high-level detonation spirit rune could be compared to the blow of a strong person in the Acquired Realm. Although it is difficult for a martial artist of the Inner Strength Realm to use a high-level Detonation Spirit Rune to injure a strong person in the Acquired Realm, under the Acquired Realm, it is definitely a sweep.

But why did the way of the Fu Seal, which was so strong thousands of years ago, suddenly declined?

Looking at the shock in Chen Tiansheng's expression, Song Wushuang teased: "Brother Tiansheng, my detonation spirit runes have run out, and I am about to make a few, do you want to watch me make detonation spirit runes, this is very rare, even if it is my sister, my own sister is not so honored." ”

Chen Tiansheng was embarrassed, with his understanding of Song Koi, she must have disdained to look at it. But he didn't expose it, and said, "Okay." ”

Seeing that Chen Tiansheng agreed, Song Wushuang quickly took out the materials for making the detonation spirit talisman from the storage bag.

An apricot-yellow rune paper, a red hair bone pen, and an inkstone.

Then he introduced: "This rune paper is not ordinary paper, but a paper specially made by me for the detonation spirit rune......"

Song Wushuang introduced a large list of them at length, and Chen Tiansheng was disturbed by it, and said, "Let's start." ”

Song Wushuang was bored with himself, and seriously picked up the red-haired bone pen, there were hollow runes on the bone tube of the bone pen, extending from the end of the pen to the top, dense and complex, and it looked quite profound.

The inkstone is not simple, there are more runes on it than on the bone pen, and it is even denser, converging from all sides to the depression in the middle.

Song Wushuang took out a small porcelain white bottle from the storage bag, uncorked it, and poured the contents into the inkstone.

The porcelain white vial was filled with blood, and it was not ordinary blood, Chen Tiansheng could faintly feel the ferocious intent emanating from it, this blood should be the blood of a barbarian beast.

When the red beast blood was poured into the inkstone, Chen Tiansheng faintly felt that the inkstone had changed a little.

Chen Tiansheng intently investigated, his pupils shrank, and the power of his eyes instantly expanded. When I looked at the inkstone again, there were some clues in my eyes.

You can see it more clearly, Chen Tiansheng's pupils shrank suddenly, and the power of "Divine Peep" suddenly expanded. Under his sharp pupils, he could see the spiritual power of heaven and earth flowing on the inkstone, using the inkstone as a medium and the beast blood as a guide, forming a small spirit gathering array.

Song Wu held the bone pen with both hands, and when he dipped it in the inkstone, the runes on the bone pen flowed, echoing the spirit gathering array on the inkstone.

Then he held his breath, it didn't seem to be a rare thing, but it made Song Wushuang very dignified, his wrist was like holding ten thousand jun, and a stroke pressed on the apricot-yellow rune paper, which seemed to consume his great mind, and layers of fine beads of sweat oozed from his forehead.

One stroke at a time, the action is smooth and smooth.

Putting away the pen and gasping, Song Wushuang's face became a little pale, and it took a while to recover.

The trajectory of Song Wushuang's pen was perceived by Chen Tiansheng's "Divine Peep", and then it was ingested into his eyes, and the movement of the pen was very subtle, echoing the runes on the bone pen.

At this moment, Chen Tiansheng had already understood the principle of detonation of the spirit rune, the cultivation of the rune seal, through the use of mystical runes, to attract the spiritual power between heaven and earth, and write it into the rune paper with the power of a warrior.

In this way, the rune paper contains the spiritual power of heaven and earth, and then through a special way, it can burst out with extraordinary power.

The spiritual power of heaven and earth is not a realm that can be touched by martial artists in the Inner Strength Realm.

It is recorded in ancient books that martial artists cultivate, forge their bodies and refine their realms, break through the realm of internal strength, and incarnate their own martial arts internal strength, but there will be a time when manpower will eventually be exhausted.

The pinnacle of the inner strength realm is to break through the shackles of oneself and listen to the heavens to achieve the realm of communicating the spiritual power of heaven and earth and turning spiritual power into one's own strength. This is also the reason why it is absolutely impossible for a martial artist of the Inner Strength Realm to defeat a martial artist of the Acquired Realm, one uses his own energy, and the other can borrow the spiritual power of heaven and earth, this is not a level of competition.

The more he understood this, the more Chen Tiansheng felt the horror of the way of the Fu Seal.

The seemingly impossible thing of communicating with the spiritual power of heaven and earth through the cultivation of the Inner Strength Realm was extremely common thousands of years ago.

Song Wushuang held up the detonation spirit rune that he had just written and said, "Brother Tiansheng, I feel that this spirit rune should be able to be completed, through the test of the last two, this one has been improved by me." ”

Chen Tiansheng was about to speak, when suddenly a middle-aged man walked in outside the door, and the man said, "You are Chen Tiansheng." ”

Chen Tiansheng nodded, and the man said again: "Mr. wants to see you, you can come with me." ”
