In the past three hundred years, there has been a rare period of calm in the cultivation realm, especially for Cui Si, since he warned the Xuangui clan last time, he has not been harassed anymore, and he has to cultivate in his jade pendant space with peace of mind.

During this period, Lei Shan'er has been in the Phoenix Clan and has not yet been released. Bing Han'er and Yuetong have both improved their strength, and now they are both people in the late stage of nothingness. Even Xue Jing has reached the middle stage of nothingness. Everyone else has also made a lot of progress, but only two people have made very little progress.

One of them is the naughty ghost tea, others cultivate, even if it is a poor ghost casual cultivator, how can he cultivate from Jindan to Yuanying. But she is good, she eats the elixir as a snack every day, but she was stunned that she was only promoted by one level, from the early stage of Jindan to the middle stage of Jindan.

At this rate, it would take her almost a thousand years to become a primordial baby! For a thousand years, even Cui Sicheng didn't spend so much effort! Anyway, with her achievement, she can already be called the first person in the cultivation world, the slowest first! And this record, I'm afraid it can be unprecedented!

However, although Cha'er's strength has not improved, her other ability has been strangely improved, that is, the Taiji diagram on her eyebrows has become closer to the way of heaven, educating people, and making it easier. Many flower demons were looked at by her a few times, and they were able to comprehend the way of heaven for no reason, so that their state of mind cultivation could be quickly improved and reach the standard of promotion. It can be seen that at least her panacea was not in vain, and she finally used the idea.

In contrast, another person who has made no progress seems to be a pure waste of time, and this person is Cui Si.

He also has no way, as an immortal, if he wants to improve his strength, he must be in the immortal realm with abundant immortal energy. There is only aura in the world, and no matter how abundant he is, he can't improve it.

Although Ice and Fire and Twin Lotus will create some immortal energy, but after their vitality is seriously damaged, their ability to create immortal qi will also decrease, and even they themselves are only encouraged to maintain, and they are powerless to help Cui Si at all.

And Cui Si couldn't compete with them for immortal qi at all, and even when he finally collected the immortal stones in the fairy world, Cui Si was reluctant to use them himself, so he gave them all of them.

Under Cui Si's care, although the two sisters did not fully recover, they also grew thriving, and they completely lost their previous malaise appearance. What makes Cui Si even happier is that the consciousness of the two sisters is completely preserved, and they are usually able to communicate with Cui Si. This also means that as long as their strength is restored to a certain level, they can immediately change back to their original appearance, and they will not change at all.

And Cui Si knew that his cultivation was useless, so he simply gave up cultivating his true qi for the time being, and instead went to specialize in cultivating and comprehending the Heavenly Dao. And spent a lot of time saving on training flower demons and building five-spell flying boats.

After three hundred years of accumulation, today's Cui Si can be described as a strong soldier. The five spells of the Half-Immortal Family produced in the Hengtu Divine Palace have refined more than one hundred and twenty Flying Boats of the Five Spells of the Half-Immortal Family. The number of Wood Five Spells also increased dramatically, and it gradually exceeded the output of the Earth Five Spells, and finally made the number of Wood Divine Boats even more, reaching one hundred and fifty ships.

Most of these flying boats were 1,200 zhang long, and only 10 reached 1,500 zhang. The reason for this is not that the five spells in Cui Si's hands are not enough, but that he doesn't have so many genuine artifacts as the core, and it is these ten genuine artifacts that are needed, and Cui Si worked hard to get them. For this reason, he even contributed his own earth-opening divine shuttle.

Without a genuine artifact as the core, the larger the flying boat, the more high-grade spirit stones will be consumed, and although Cui Si is rich, he can't supply hundreds of large flying boats.

Therefore, those secondary flying boats, Cui Si also installed pseudo-immortal weapons as cores, although they are not as powerful as the immortal core, but they are enough to support the operation of 1,200 zhang flying boats.

With so many five-spell flying boats, Cui Si's confidence also became sufficient. However, he still hasn't shown these big killer weapons in front of others. Most of the flying boats were hidden, and only about ten were left outside for people to see.

Even those ten, together with the powerful Five Elements Divine Boat and the Chilling Ice Divine Boat, have become an extremely powerful force. It's enough to fight against any super sect.

If Cui Si's hidden army came out together, he would almost be able to sweep through half of the cultivation realm. And such a powerful armed force has not yet satisfied Cui Si, and he is still keeping the flower demons below to step up manufacturing, and continue to increase the inventory with the number of one per year.

It doesn't matter if the follow-up flying boats don't have immortal cores, Cui Si plans to use them as backups! When you have an immortal weapon, you can upgrade it to a top-level flying boat that can fight.

In addition, they are extremely useful in the event of a major war. In the unlikely event that the flying ship on the front line is damaged and needs to be overhauled, the core can be replaced so that it can be quickly put into battle. Of course, in the past three hundred years, Cui Si has not completely copied the design of the Five Dharma Daoists. He himself also made necessary changes to the Five Spell Flying Boat according to the actual combat situation.

The main changes are two, one is the way to supplement the core aura, and the other is the Five Spell Tower.

It turned out that when Cui Si was commanding ten five-spell flying boats at the same time and conducting combat exercises, he suddenly discovered an extremely serious problem, a big problem that would turn his flying boat fleet into garbage. It was in response to this problem that he was forced to transform and upgrade Shenzhou.

And this problem is the power problem of the Five Spell Flying Boat. You must know that all the top flying boats in the cultivation realm are based on genuine immortal weapons, so that when they are fighting, they can use the special abilities of immortal weapons to continuously absorb the aura of the surrounding heaven and earth, and quickly replenish and consume.

Because the speed at which the immortal weapon absorbs the vitality is super fast, it is even greater than the usual consumption of the top-level flying boat, so it makes this top-level flying boat a war fortress that will never fall, and can even confront the scattered immortals.

However, in the cultivation realm, top-level flying boats are extremely rare, and there are only one or two of them in each super sect, so that even if it is a sect war, there will not be many top-level flying boats gathered.

Even in the spiritual realm where the aura is poor, the huge realm is filled with a sufficient amount of aura to supply the consumption of several top-level flying ships. So in general, this is not a problem at all.
