The formation in the middle of the ninth level is transformed into a sword formation, and the power is comparable to the realm of Immortal Venerable, as for being able to reach a few star Immortal Venerable, Liu Bo can't guess it for the time being, which needs to be known after he really reaches this realm.

Liu Bo is now well-known in the entire immortal realm, and the people who associate with him are at least in the realm of immortal zun, and his future opponents will definitely be in the same realm, Liu Bo is only the strength of the realm of immortal monarchs, and it is difficult to ensure his own safety. Therefore, Liu Bo decided that even if he spent more Golden Lotus Miaowu Pill, he would also improve his combat power to the realm of Immortal Venerable.

Since in terms of the law, he can't break through for the time being, so Liu Bo pinned all his hopes on the formation. He was going to do a long retreat, when he reached the middle stage of the ninth-level formation, and when he would go out.

The breakthrough of the formation requires the highest comprehension, and it is also the most time-consuming ability, and many immortals who are talented in the formation do not dare to waste too much time in this regard, and can only consult in their leisure time, so as not to delay the comprehension of the main law.

In order to reach the ninth level of the formation cultivation, every bit of improvement was extremely difficult, and although Liu Bo had an excellent talent, coupled with the assistance of the Golden Lotus Miaowu Pill, he was still moved to make slow progress. In the past, Liu Bo's comprehension formations went hand in hand as a whole, and after feeling the difficulty of the ninth-level formation, Liu Bo had to dispel this idea.

If the various formations were still advancing at the same time, even if all the Golden Lotus Miaowu Pills with 200,000 years of medicinal effect were used up, Liu Bo might not be able to reach the middle stage of the ninth-level formation. Now Liu Bo is eager to improve his own strength, and can only make some changes according to demand. His immediate priority was to raise the power of the sword array to the Immortal Venerable realm, and it would take the least amount of time. In order to achieve this goal, it is the best way for Liu Bo to choose a formation for in-depth study.

After careful consideration, Liu Bo finally decided to choose the killing array as the direction of his main attack. For the sword array, the killing array can best exert the power of the sword array, as long as Liu Bo's research on the killing array reaches the mid-ninth level realm, his sword array can exert the power of the Immortal Venerable. Although such a sword formation lacks a defensive advantage, as long as Liu Bo can overwhelm the opponent in attack. He didn't need to defend himself. If he encounters an opponent whose strength is beyond his, his defense can only rely on various magic weapons.

After choosing the main direction of attack, Liu Bo began to swallow the Golden Lotus Miaowu Pill and forgot all distracting thoughts. Put all your energy into the comprehension of the formation. By the time the 200,000-year-old Golden Lotus Miaowu Pill was exhausted, his achievements in the killing array had finally barely reached the realm of ordinary Immortal Venerable.

The higher the cultivation of the formation, the more Liu Bo understood the breadth and profundity of the formation. After nearly four years of enlightenment, Liu Bo has become more obsessed with the study of formations, but it is a pity that he can't spend all his time in this area. The time must be arranged as a whole, with the first purpose of improving strength.

When the formation realm reached the middle of the ninth level, Liu Bo still needed to combine the comprehension of the formation with the sword formation in order to truly transform it into actual combat power. It took him another two months, and the mid-ninth level sword formation was finally completely controlled.

Although Liu Bo was able to cast a mid-ninth level sword formation, but casting a sword formation across three realms would consume too much mana, and it would be difficult for him to maintain a supply of his own mana, and if this aspect of the problem was not solved, his strength would of course be greatly reduced.

To solve this problem. This can be achieved in two ways. One way is to refine an elixir that can greatly increase mana, and the other way is to increase the total amount of innate qi and use innate qi to make up for the lack of mana.

With Liu Bo's current ability, these two methods can be implemented at the same time. Among the Danbang Dan recipes he now mastered, there was one of the best elixirs for increasing mana, and that was the Zijin Dan, which ranked eleventh on the Dan List.

The most effective Zijin Pill, a single pill can make the Nine Star Immortal Venerable increase mana for millions of years, and it is precisely because of such a powerful effect that the Zijin Pill ranks so high in the Dan list.

Zijin Dan is the most widely circulated elixir in the Danbang Dan formula, and a complete Dan prescription requires a total of ten extremely cherished main medicines. Ninety other excipients. But these ten main drugs are too cherished, and it is too difficult to get them all together. In the long years, there are senior Dan masters who have made appropriate improvements to the Dan prescription of Zijin Dan, even if the ten main medicines are incomplete. It is also possible to refine the castrated version of the Zijin Dan, and this castrated version of the Dan prescription only needs at least one main medicine and nine auxiliary drugs to refine. Although the efficacy is greatly reduced, it is more popular because of the decrease in the number of elixirs needed.

Liu Bo's current strength is only Taiyi Golden Immortal, even if it is a castrated version of the Zijin Dan Dan Fang. It can also greatly increase his mana.

In addition to the Zijin Pill, Liu Bo also planned to use the Demon Beast Inner Pill to create an original pill to increase mana.

The stronger the demon beast, the more chaotic and violent the inner dan is. In the entire immortal realm, even if the alchemy master is at most, he can only use the demon beast inner pill of the immortal monarch level to refine the elixir, and the medicinal effect is very poor, and it is not taken seriously.

Liu Bo has the Beast Attraction Grass in his hand, which can completely solve the drawback of the Demon Inner Pill, but the cultivation period of his Beast Attraction Grass is too short, and the medicinal effect is too poor, so it is difficult to match with the high-grade Demon Beast Inner Pill. If he wants to realize this idea, he still needs to focus on cultivating the Beast Guiding Grass, and wait for a while before he can start refining.

Fortunately, Liu Bo has been able to transform the innate qi, and the growth rate of all the elixirs in the environment of the innate qi has accelerated a lot, and Liu Bo's idea will become a reality one day.

If it is more convenient to obtain innate qi, as long as Liu Bo exchanges all the Danbang Immortal Pills accumulated in his hands with the best immortal crystals. In order to create the greatest value for the Danbang elixir in his hand, Liu Bo decided to hold a grand auction.

Liu Bo has been in retreat for five years, and now that his true combat power has reached the realm of ordinary Immortal Venerable, and he has a plan for the next step, he can already get out of the customs.

Hearing the news of Liu Bo's exit, the first person to come to the door was Gu Yan Xianzun.

After the two exchanged pleasantries, Liu Bo took the initiative to say: "This retreat alchemy, finally live up to the trust of the Immortal Venerable, this purple jade barrier-breaking pill please take it away from the Immortal Venerable." ”

Receiving the jade bottle handed by Liu Bo, Gu Yan's face showed uncontrollable joy, and he couldn't wait to open the jade bottle.

Gu Yan's divine sense penetrated into the jade bottle, and he was even happier to see that this purple jade barrier breaking pill turned out to be a medium-grade quality. According to the usual practice, no matter how many pills Liu Bo refines, he only needs to give him a low-grade elixir to explain. He originally thought that Liu Bo must have given him a low-grade pill, but he didn't expect it to exceed his expectations. With this medium-grade elixir, his chances of breaking through the existing bottleneck have increased a lot
