Liu Bo successfully cultivated the "Fireball Bullet", and then it was relatively easy to cultivate the second-grade spiritual skill "Flame Arrow". Although the Flame Arrow is a second-grade spiritual skill, with the assistance of the spiritual fire in the dantian, it is not difficult to comprehend. It didn't take long for him to master the tricks of the "Flame Arrow".

After actually casting it, the power of the flame arrow was indeed much greater than that of the fireball bullet. The flame arrow is more concentrated than the fireball bullet attack, and the power of the single attack is naturally greater, and a bottomless arrow hole is directly pierced on the opposite stone wall.

Next, Liu Bo practiced "Colorful Fire and Rain" and "Flame Shield" respectively.

The attack range of Fire Rain is very large, and the power is no less than that of Fireball Bullets, but there is also a disadvantage that it consumes too much True Qi. With his current cultivation, I'm afraid he can only cast it about ten times, and this is because of the help of the spiritual fire in the dantian, otherwise once he casts it, Liu Bo's true qi will be exhausted.

The flame shield is a kind of defensive spiritual skill, and because no one cooperated with the attack during Liu Bo's practice, it was difficult to test the degree of defense of this spiritual skill, and he just guessed that the defensive power of this spiritual skill should be very extraordinary.

Liu Bo can be regarded as a great gain in this day, not only did he advance to the fire system exercises, but he also accidentally introduced the "Spark Inheritance" exercises, and also learned four primary spiritual skills. With such great progress in cultivation, Liu Bo was very satisfied.

After getting all the exercises of "Spark Inheritance", Liu Bo's horizons have expanded a lot, this top-level exercise is all-encompassing, in addition to the detailed introduction of the exercises, there is also a lot of relevant knowledge. After reading these, Liu Bo realized that no matter whether it was down to the heavenly weapon or up to the immortal weapon, it could be refined, and after the blood refining was successful, the magic weapon would initially recognize the owner and could be recuperated in the dantian. However, once the blood refining is carried out and the magic weapon is completely refined, if the magic weapon is damaged, then the soul origin of the person will also be damaged that is difficult to recover. Because of the drawbacks of blood refining, there is generally no blood refining for low-grade and medium-grade celestial weapons. Even those who are sure to have no spiritual root will generally do their best, and at the very least, they will choose a top-grade celestial weapon as a natal celestial weapon for blood refining.

After Qiankun Ding recognized the master, Liu Bo knew that there was still a seal on Dingxin that had not been completely broken, and he had been impacting the seal for a long time. Although there is still a faint trace of the seal on Dingxin, his strength is too low, and there has been no obvious effect.

There is a very advanced method of breaking the seal of the blood sacrifice in the "Spark Inheritance" exercise, which can be used right now.

He used his essence and blood to draw a complex large array on the stone slab, placed the Qiankun Ding in the center of the array, and then pinched the law with his hand to trigger the formation. I saw a flash of blood light in the array, and this blood light drilled into the Qiankun Ding one after another. It wasn't until the blood stains on the stone slab disappeared and completely integrated into the Qiankun Ding that Liu Bo ended the blood sacrifice and included the Qiankun Ding in the dantian.

According to the introduction of the jade slip, after the blood sacrifice, the magic weapon of the blood sacrifice is put into the dantian, and then the true yuan is used to impact, and the seal will be much easier to break.

Liu Bo struck while the iron was hot, and with the help of the concentration of aura here that far exceeded the outside world, it was a good opportunity to break the seal of Qiankun Ding.

Sitting cross-legged on the futon, Liu Bo ran the "Spark Salary" exercise, absorbing the aura of the outside world with all his might, and impacting the seal of Dingxin.

In the blink of an eye, a day passed, and Liu Bo did not waste the slightest time except for eating a Bigu Dan.

Although it was only one day, because Liu Bo's meridian strength could withstand the impact of aura, he had always maintained a state of absorbing aura with all his might. One day's cultivation is equivalent to more than a month of sleepless cultivation in the outside world. And the effect of such an all-out cultivation is really huge, not only has the seal of Qiankun Ding been loosened a little, but also the fire system exercises that have just reached the sixth layer of qi cultivation yesterday have also been cultivated to the peak of the sixth layer, as long as he is ready, he can break through the bottleneck at any time and reach the realm of the seventh layer of qi training, which is comparable to the water system exercises he is cultivating now.

In the following time, Liu Bo continued to break the seal of Qiankun Ding, and at the same time worked hard to practice the "Spark Inheritance" and "Good Water Heart Sutra" exercises.

The "Spark Inheritance" exercise had already reached the peak of the sixth layer of qi training, and as long as he was prepared, he could break through the bottleneck in one fell swoop and reach the seventh level of qi training.

Now that even the biggest concern for breaking the seal finally had hope, and Liu Bo began to put all his energy into cultivation.

With the help of the strong heaven and earth aura in the cultivation room, Liu Bo really easily broke through the bottleneck, and the "Spark Inheritance" exercise also reached the realm of the seventh layer of qi training, and now his fire and water system exercises have reached the same realm, and they have all reached the realm of the seventh layer of qi training.

Since his meridians were fully able to withstand the impact of the strong aura here, the rare cultivation environment here was naturally to be cherished. Taking advantage of the only ten days before the inheritance of the rune, Liu Bo cultivated all the two exercises of "Spark Inheritance" and "Good Water Heart Sutra" to the realm of the eighth layer of qi cultivation in one fell swoop.

During this time, Liu Bo has been going all out to impact the seal of Dingxin, although he still has not been able to completely break it, but the ban has also been greatly loosened, Liu Bo believes that if he can continue to cultivate in such an aura rich environment, then as long as it takes about a month, he will completely break the seal of Qiankun Ding.

"It seems that after the inheritance is over, I have to find a suitable excuse to continue to cultivate here, otherwise if I want to break the seal of Dingxin under the aura environment of the outside world, it will be far away. "But what excuse to use, not only to let him continue to come here to cultivate, but also not to let others suspect him, Liu Bo has to think about it.

Ten days have passed in a flash.

"Xiaobo, follow me to the Inheritance Hall to receive the inheritance. Xiao Yan, they have all arrived, and now you are alone. Liu Tianxiong, who had not seen him for ten days, came to the cultivation room and said.

"Okay, grandpa. I'll go with you right away. At this time, Liu Bo did not cultivate, and immediately got up and walked with his grandfather.

While the two were walking, Liu Tianxiong asked Liu Bo about his cultivation in the past few days.

As Liu Bo was talking, Liu Tianxiong suddenly stopped, his eyes widened, and he said in shock: "Xiaobo, you have already cultivated the eighth-layer realm of qi! Why didn't you tell me about such an important matter?"

"Grandpa, you haven't asked yet, I was about to tell you. Liu Bo said innocently.

"How can it be so fast? It's only ten days to get full, how did you break through from the seventh layer of Qi training to the eighth layer of Qi training?" Liu Tianxiong was both surprised and a little worried.

"The aura of heaven and earth here is so strong, my cultivation speed is very fast, and it is easy to reach the eighth level of qi cultivation. ”

"The cultivation speed is fast, you won't be blindly greedy and damage the meridians, right?" Liu Tianxiong said, grabbing Liu Bo's left hand with his probing hand, and using his true qi to carefully probe the meridians in his body.

"Your meridians are very wide, and your flexibility is very good! Yes, there is no damage to your meridians. After the investigation, Liu Tianxiong finally put his mind at ease.

"You have been stagnant in your meridians since you were a child, how can the breadth and flexibility of your meridians now far exceed ordinary people?" asked Liu Tianxiong suspiciously.
