After leaving the exchange, Cang Jian came to a simple and thick tower-shaped building, which was the holy place in the academy, the cultivation tower.

Cang Jian used to come here to practice before, even if his cultivation had been stagnant, Cang Jian still did not give up his cultivation. There are still many people in front of the tower, some in and some out. In the middle of this tower, there are a few big characters written, Cultivation Tower.

Cang Jian walked into the tower, the inside of this building was much larger than the outside, Cang Jian went directly to the top seven floors to find the cultivation room, there were more people below, and ordinary disciples rarely went to the seventh floor to cultivate. There are two lights at the door of each door, one is red and the other is green, and if the red is on, then it means that someone is cultivating inside. If the light is green, it means that there is no one inside, and it can be used normally. There is also a bell at the door of the cultivation room, if someone is cultivating in the room, but there is an emergency, then the bell can be used to wake up the person inside from the cultivation state.

After Cang Jian found a cultivation room, he immediately locked himself in the room, and couldn't wait to take out the materials he had just purchased, ready to start refining the runes.

To learn rune spells, you must not only have a good understanding, but also have a good teacher and strong financial support, but an excellent rune spell is not short of money. Cang Jian thinks that his comprehension should be quite good, teacher, he doesn't have to worry if he has all the memories of Rahu, if you have money, it's a problem now, but it won't be an obstacle, the most important thing is your soul power.

Because in the process of drawing the runes, it is necessary to control the structure and order of the energy in the runes in the soul. When Cangjian was young, he tested his soul power, six grades. Decent, not particularly powerful and not particularly bad. And when he was a child, Cang Jian didn't want to become a rune mage at all, and he didn't meet the conditions. Everyone doesn't care much about this soul power.

Because there are not many places where soul cultivators use soul power in the early stage of spiritual cultivation, Cangjian used a soul power before when he fused his memory. But that was just a random use, after fusing that part of the memory, Cang Jian got a soul decision, and now he is also running the soul law decision, and began to use the soul power in his spirit sea.

Everyone has soul power, but there are very few people who can call him, and generally if a spiritual cultivator wants to call soul power, it is after obtaining the Spirit Emperor Realm, and at that time, if he defeats the enemy, he can devour the enemy's primordial spirit. After all, not everyone wants to have an opportunity like Cangjian, but the third layer of Gathering Spirits devoured the primordial spirit of a Spirit Sect. If you want to invoke soul power, you need soul law, and you need to practice day after day, many rune mages have finally memorized various rune symbols and basic theories, but when learning soul law, they always can't enter the door, soul power can't be used, materials can't be used, and as a result, nothing can be done.

After Cangjian ran the soul law, he immediately felt a sense of familiarity from the depths of his memory, this set of law, Rahu's predecessors must have used it countless times during his lifetime, this familiarity is that the consciousness of the original god has dissipated, but it is still retained in the memory. This made Cang Jian save too much effort, just like when cultivating the Chaos True Yuan Duel, Cang Jian didn't spend too much effort to easily touch the threshold.

As soon as he stretched out his hand gently, the invisible soul power pulled the Heavenly Spirit Grass and Blood Lingzhi on the side, and with a movement of his heart, a ball of soul fire began to refine these two medicinal materials, and in a short time, they turned into two bottles of medicinal liquid. With the change of Cang Jian's mind, a drop of the medicinal liquid of the Heavenly Spirit Grass appeared in various shapes under the control of Cang Jian, sometimes being pulled into filaments, sometimes condensed into clear droplets.

Handy, like an arm to make a finger. This feeling made Cang Jian marvel, Cang Jian had also been in contact with the soul law before, if you want to learn the soul law well, it will take a month for people with good understanding, and people with poor understanding may not have results after half a year of hard practice.

Every rune master has his own soul law, and the soul law is both inferior and superior, and the rune mage is not self-cherishing this, and the ugliness of the family cannot be publicized. Even their own disciples may not be able to teach each other. Because the advantages and disadvantages of this soul law decision can expose all the weaknesses of the rune mage, and the soul law decision that Cangjian is now cultivating is the biggest reliance of Rahu during his lifetime [Sanqing Soul Decision], from Luo Hu's memory, Cangjian got the three law decisions, the first [Chaos True Yuan Decision], changed the nature of Cangjian's spiritual power, and evolved the spiritual power into true yuan, the second book of Cangjian has not had time to practice the body training law decision [Eight Doors Quenching Pulp Sutra], and the third book is the soul law decision [Sanqing Soul Decision] obtained by fusing memories before.

Although these three exercises are not top-notch exercises, they are definitely the best in the Immortal Spirit Continent.

Cangjian's own soul power is only a sixth-grade, but since Cangjian is now extremely familiar with this soul method, his sixth-grade soul talent can be regarded as a seventh, or even an eighth-grade!

Now the rune that Cangjian wants to draw is also inherited from Rahu's memory, a third-level rune. Of course, it is impossible for the current Cangjian to draw a third-level rune, this is a simplified third-level rune, and it is a third-level rune that cannot be simplified, even the materials are mortal level, and the blood of the demonic beast is also the blood of the first-level demonic beast used. This is a simplified version of the rune created by Rahu for his disciples, just to familiarize the apprentices with the process of drawing runes, and now it is also convenient for Cangjian to get started.

These are the wealth left by Rahu's Yuan Shen, the ten fingers quickly pinched a seal, a blank rune paper floated in the air, and then Cangjian's fingers slashed in the air, and the medicinal liquid of the blood lingzhi and the heavenly spirit grass also began to merge into the rune paper, as the fingertip flashed, Cangjian injected the true yuan into the medicinal liquid, and the heavenly spirit herbal liquid that fused the true yuan quickly formed a mysterious and beautiful rune.
