The mid-stage formation of the ninth level is transformed into a sword formation, and its power is comparable to that of the Immortal Lord. As for how many stars of the Immortal Lord can reach, Liu Bo cannot guess for the time being. This requires him to truly reach this level before he can know it.

Liu Bo is now well-known in the entire fairy world. The lowest figures he dates are at the Immortal Lord realm, and his future opponents will definitely be at the same level. Liu Bo is only at the Immortal Lord realm, so it is difficult for him to ensure his own safety. Therefore, Liu Bo decided that no matter how much Golden Lotus Miaowu Pill is spent, he would have to upgrade his combat power to the Immortal Lord realm.

Since he cannot break through the law for the time being, Liu Bo will place all his hopes on the formation. He is planning to go into a long retreat, when will he reach the mid-stage of the nine-level formation, and when will he come out of the seclusion?

The breakthrough of formations requires the highest understanding and is also the most time-consuming ability. Many immortals with talent in formations dare not waste too much time in this regard. They can only comprehend in their spare time, so as not to delay comprehend the main practice rules.

The formation cultivation reached the ninth level, and every point of improvement was extremely difficult. Although Liu Bo had excellent talent and the assistance of the Golden Lotus Miaowu Dan, he was still moved and made progress slowly. In the past, Liu Bo had to understand the formations in a whole. After feeling the difficulty of the ninth level formation, Liu Bo had to give up this idea.

If all kinds of formations are still moving forward together, even if all the Golden Lotus Miaowu Pill with 200,000 years of medicinal effect is used up, Liu Bo may not be able to reach the middle stage of the ninth-level formation. Now Liu Bo is eager to improve his own strength, so he can only make some changes according to his needs. His top priority is to increase the power of the sword formation to the realm of the Immortal Lord, and it takes the least time to achieve this goal, Liu Bo chooses a formation to conduct in-depth research, which is the best way.

After careful consideration, Liu Bo finally decided to choose the killing formation as the direction of his main attack. For the sword formation, the killing formation can best exert the power of the sword formation. As long as Liu Bo's research on the killing formation reaches the mid-stage level of level 9, his sword formation can exert the power of the Immortal Lord. Although such a sword formation lacks the advantage in defense, as long as Liu Bo can overwhelm the opponent in the offensive, he does not need defense. If he encounters an opponent whose strength exceeds him, his defense can only rely on various magic weapons.

After choosing the main attack direction, Liu Bo began to swallow the Golden Lotus Miaowu Pill, forgetting all his distractions, and devoted all his energy to the understanding of the formation. When the Golden Lotus Miaowu Pill, which had a medicinal effect for 200,000 years, was exhausted, and his achievements in the killing formation finally barely reached the realm of an ordinary immortal.

The higher the formation cultivation level, the more Liu Bo understood the profoundness of the formation. After nearly four years of comprehending, Liu Bo became more obsessed with the research on formations. Unfortunately, he could not spend all his time in this regard. Time must be arranged in a coordinated manner, with the first goal of improving his strength.

When the formation realm reaches the mid-stage level of level 9, Liu Bo still needs to combine the understanding of the formation with the sword formation to truly transform it into actual combat power. It took him another two months to finally control the mid-stage sword formation in the mid-stage level 9.

Although Liu Bo can cast the mid-stage sword formation at level 9, it consumes too much mana to use his own mana to maintain supply. If the problem in this regard is not solved, his strength will of course be greatly reduced.

To solve this problem, you can achieve it from two aspects. One method is to refine elixirs that can greatly increase mana, and the other method is to increase the total amount of innate qi and use innate qi to make up for the shortcomings of mana.

With Liu Bo's current abilities, these two methods can be implemented at the same time. Among the elixir recipes he has mastered now, there is a kind of best immortal pill to increase mana, that is, the Zijin Pill, which ranks eleventh in the elixir list.

The most powerful purple gold elixir can increase the magic power of the Nine Star Immortal Lord by millions of years. It is precisely because of such powerful effects that the purple gold elixir ranks so high on the elixir list.

Zijin Dan is the most widely circulated immortal pill among the Danbang elixir recipes. A complete pill recipe requires a total of ten extremely precious main medicines and ninety other auxiliary medicines. However, these ten main medicines are too cherished, and it is too difficult to get them all together. Over the long years, a senior alchemist has made appropriate improvements to the Zijin Dan prescription. Even if the ten main medicines are not complete, you can also refine a castrated version of Zijin Dan. This castrated pill recipe requires at least one main medicine and nine auxiliary medicines to be refined. Although the efficacy is greatly reduced, it is more popular because the number of required immortal medicines is reduced.

Liu Bo's current strength is only Taiyi Jinxian. Even the castrated version of the Zijin Dan Pill recipe can greatly enhance his magic power.

In addition to the purple gold elixir, Liu Bo is also preparing to use the inner elixir of monster beasts to create a unique pill to increase magic power.

The stronger the monster, the more violent the inner elixir is. In the entire fairy world, even the alchemy master can only use the inner elixir of the Immortal Lord level monster to refine elixirs, and the medicine is very poor and is not valued.

Liu Bo has the beast-inducing grass in his hands, which can completely solve the disadvantage of the demon inner alchemy. However, his beast-inducing grass is planted for too short and the medicinal effect is too poor, so it is difficult to match the high-level monster-inducing animal inner alchemy. If he wants to realize this idea, he still needs to focus on cultivating the beast-inducing grass and wait for a while before he can start refining.

Fortunately, Liu Bo has been able to transform the innate qi. All spiritual medicines have accelerated their growth rate much faster in the environment of innate qi. Liu Bo's idea will become a reality one day.

If you want to obtain innate energy, just replace all the elixirs accumulated in your hands with top-quality immortal crystals. In order to create the greatest value of the elixirs in your hands, Liu Bo decided to hold a grand auction.

Liu Bo has been in seclusion for five years, and now his true combat power has reached the realm of an ordinary immortal master. With the next plan, he can already get out of seclusion.

When he heard that Liu Bo had left the seclusion, the first person to come to Gu Yan Immortal Lord.

After the two of them greeted each other, Liu Bo took the initiative to say: "This time I went to seclusion and refining the alchemy, I finally did not let the Immortal Lord down. Please collect this purple jade barrier-breaking pill."

After taking the jade bottle handed over by Liu Bo, Gu Yan showed an uncontrollable joy on her face, and she couldn't wait to open the jade bottle.

Gu Yan's spiritual sense penetrated into the jade bottle and saw that this purple jade barrier-breaking pill was actually of medium-grade quality. According to convention, no matter how many pills Liu Bo refined, he only needed to give him a low-grade immortal pill to explain. He thought that what Liu Bo gave him must be a low-grade elixir, but he did not expect that it would exceed his expectations. With this medium-grade immortal pill, his chance of breaking through the existing bottleneck increased a lot.
