Liu Bo carefully studied these spiritual fires according to the instructions next to the spiritual fire, such a precious fire, of course he had to seize the opportunity, and he must choose the most suitable kind of first-grade spiritual fire for his own use.

Of these sixteen kinds of spiritual fire, the highest is the four-grade spiritual fire, of which there are seven kinds of first-grade spiritual fire, four kinds of yang fire, and three kinds of yin fire. Liu Bo carefully considered it and consulted his grandfather's opinion, and then he chose one of the yin fires, "Cold Pulp Cold Flame".

This "cold marrow cold flame" emitted a cold and faint light in the transparent jade box, quiet and charming, and it didn't seem to be harmful.

"This 'Cold Marrow Cold Flame' is very suitable for the 'Xuanbing Cold Flame' you are practicing now, your current realm is only the seventh layer of Qi cultivation, and you can't really absorb this spiritual fire, but you can try to absorb the aura of this spiritual fire from now on, which can not only increase the cold flame attribute of the true qi, but also lay the foundation for completely absorbing this spiritual fire in the future. When you absorb the breath, you only need to open the lid of the box, don't touch the entity of the spiritual fire, you can only absorb the breath of the spiritual fire, otherwise once you touch the entity of the spiritual fire, with your current strength, you will definitely be burned into a cloud of ashes. Liu Tianxiong solemnly admonished.

"I see, Grandpa. When absorbing the aura of spiritual fire, I will definitely be very careful and never touch the entity of spiritual fire. Regarding his grandfather's admonition, Liu Bo did not dare to take it lightly.

"Also, this jade box that holds spiritual fire is also very precious, and this jade box can hold up to six spiritual fires. After you have thoroughly absorbed this spiritual fire, the jade box should also be carefully collected, and its value is not much inferior to this first-grade spiritual fire. Liu Tianxiong added.

"Ah, the jade box is also so precious! Now I have earned it, doesn't this mean that I have obtained two kinds of spiritual fire?" Liu Bo said in surprise.

"In terms of value, this is indeed the case, so after you absorb the spiritual fire, if you don't use the jade box, it's best to return the jade box, and the bottom line is that this kind of jade box is never allowed to be lost. Liu Tianxiong continued.

"Got it, grandpa. Return it back, I don't think it will be necessary for the time being, and I am still looking forward to using this jade box to continue to carry other varieties of spiritual fire one day, as for the loss of it, it will definitely not appear. "I heard that this jade box is so precious, how can Liu Bo be willing to return it again.

"Since the spiritual fire has been handed over to you, I will simply teach you the 'Spark Inheritance' technique at one time. Liu Tianxiong said, walked out of the secret room, and took back a piece of jade slip.

"Next, I will teach you the exercises in the jade slip, abandon distracting thoughts, and concentrate your energy. There will be some pain when teaching, and it is important to hold on. ”

Liu Tianxiong said, pasting the jade slip on Liu Bo's eyebrows with his left hand, and playing a series of legal decisions with his right hand.

Liu Bo only felt that countless words rushed into his mind, and as time went on, his brain became more and more swollen, but the information coming in from the jade slip did not stop at all, he only felt that his brain was becoming more and more painful, as if it would explode at any time.

Just when he felt that his brain was about to explode, the transmission of the jade slip finally stopped, and the brain was also cool, and the countless words that came into the jade slip seemed to be imprinted in his mind, which was extremely profound.

"Xiaobo, Grandpa has imprinted all the contents of the 'Spark Inheritance' concentrating period to the Earth Immortal stage in your sea of consciousness, and when you reach the condensation stage, you can rely on the 'Cold Marrow Cold Flame' to cultivate. The 'Spark Inheritance' exercise is the top fire system exercise in our Liu Mansion, you must practice hard, and you must also pay attention to secrecy to the outside world, and there can be no leakage in the slightest. Liu Tianxiong finished transmitting the contents of the jade slip, and his face showed a trace of tiredness.

Liu Bo didn't expect that this piece of jade slip actually contained all the cultivation exercises below the Earth Immortal Stage, no wonder his brain was so painful when he accepted the inheritance, and he was very excited in his heart, and said: "To be able to get the inheritance of the top fire technique in the family, my grandson must cultivate hard and live up to the expectations of my grandfather and the family." In any case, even if I die, I will not reveal the slightest secret of the exercises. ”

"The aura here is more than fifty times that of the outside world, Xiaobo's realm is too low, and he must reach the realm of the peak of the ninth layer of qi cultivation before the Shenxiao trial, if he can break through to the condensing period, it will be even more perfect. Only by reaching such a realm can one be more likely to obtain the qualification of an inner disciple of the Shenxiao Sect in the end. You will be here to cultivate for a period of time temporarily, don't be in a hurry when cultivating, the aura here is still too strong for you, you must be steady and steady, don't rush to break through the bottleneck. As for Xiao Yan, there is no need to cultivate here, you have already cultivated to the bottleneck of the concentrating period, and the most important thing now is to increase the realm of comprehension, there is no need to increase the accumulation of true qi. Liu Tianxiong said to the two.

Liu Tianxiong took Liu Bo and the two of them to visit all kinds of collections in the secret vault, which opened their eyes, not only for the common precious items, but also for some cold and strange things.

After visiting the secret vault, Liu Tianxiong sent Liu Yan out of the secret vault, and after returning, he arranged Liu Bo in a cultivation room.

"Xiaobo, you usually cultivate in this cultivation room, and you can go around when you are bored. But you must not enter the other cultivation rooms, except for the one you are staying in now and a few cultivation rooms nearby, the other cultivation rooms are equipped with different levels of spirit gathering arrays. You are cultivating in other cultivation rooms, and the strong aura is in danger of making you go mad, so don't go in. Liu Tianxiong admonished solemnly.

"Don't worry, grandpa. I can just cultivate in this cultivation room, and I won't go to other cultivation rooms. ”

Liu Bo has always been an obedient and sensible child, Liu Tianxiong was very relieved of him, and after explaining all the matters that should be paid attention to, he went to his usual cultivation room to cultivate.

After Liu Tianxiong left, Liu Bo took out the "Cold Marrow Cold Flame" and three shadow needles he had just gotten.

He scrutinized the three Shadow Needles. These three shadow needles are all dark gold, and with Liu Bo's current knowledge, he can't tell what material the needles are made of. The tip of the needle emits a faint cold light, and you don't need to try it to know that the tip of the needle must be extremely sharp; although it is only three thin needles, Liu Bo actually feels like a drop in his hand, such a large weight, even if it is used in an ordinary way, the power of this shadow needle will be extremely great.

He took out the introduction of the Shadow Needle, and his consciousness sank into it, carefully browsing the introduction to the use of the Shadow Needle. He hadn't cultivated his divine consciousness yet, so the content in the jade slip could only be browsed, and he couldn't use the law to completely engrave the content of the jade slip into his mind like Liu Tianxiong did. Fortunately, there is not much content in Yujian, and it doesn't take long for Liu Bo to completely browse it.

According to the content of the jade slip, if you can cultivate the divine sense brand and recognize the master, these three shadow needles can be collected into the dantian qi sea for warmth, and the sending and receiving can be operated flexibly as long as one thought is made, so that the use of shadow needles is even more elusive and difficult to guard against.
