The flying sword is made of strong material and sharp, and it is used to kill people and seal the throat with blood, and it is used to dig the ground, which is also a good hand.

In particular, there is the ability to zoom in and out, although there is a certain limit, but it is no problem to make it the size of a door panel.

A flying sword the size of a door panel, digging down once is a deep pit, and there are not a few soil dug out.

Lin Yi's huge divine sense, controlling the take-off sword without any sense of obstruction, dug deep again and again, and in less than a few minutes, Lin Yi dug a deep pit fifty or sixty meters deep.

Ordinary people looked down from the top, it was dark, they couldn't see anything clearly, and only with their divine sense could they peek into the bottom.

Then there was the widening and reinforcement, a task that required a small construction team to work for a day, which was solved by Lin Yi in just a few minutes.

Next is the laying material.

The materials to prevent leakage Lin Yi have already purchased on the exchange platform and will be delivered soon.

He had used the same thing when he was building the Spirit Spring before, and he was already very proficient.

It's just that this time the amount needed is a bit large.

This kind of leak-proof material was also available before the revival of Reiki, but after the revival of Reiki, it was greatly changed by a company, which not only has the function of preventing liquid leakage, but also has a good effect in hindering the escape of Reiki.

For Lin Yi, the ability to hinder the escape of spiritual energy is actually average, how can the spiritual liquid condensed by the concentration of spiritual energy in the air being too high, how could it be possible to change back again.

There are a large number of new materials, but the delivery speed is very fast, not long after Lin Yi placed an order, the company sent the new materials to the gate of the Aoki Sect, and after Ning Xiuyuan signed for it, he called a few disciples to help Lin Yi transport it to the foot of Qifeng Mountain.

After getting the materials, Lin Yi's consciousness moved, and the materials flew in the sky, and then quickly and tightly laid around the deep pit, pasting the deep pit of the soil structure like a silver-white channel.

In this way, a deep pool for storing spiritual liquid has been built.

Lin Yi transferred the previously set spiritual liquid generation port to the bottom of the pool, and then with a wave of his hand, he transferred all the previous spring water to the deep pool.

Originally, the number of spiritual springs that were okay only filled one-tenth of the range of the deep pool.

"Not bad." Lin Yi looked at the spiritual fluid that was constantly being produced, as well as the deep pool of the remaining huge space, and nodded with satisfaction.

Such a large amount of spiritual fluid can withstand his wanton squandering.

However, this deep pool also caused Lin Yi to think about it again.

How should I develop myself in the future?

Qifeng Mountain is too small, and at present, the spirit plants are fully second-order, and many tall spirit plants are crowded on one mountain, which is a little stretched.

Some of the second-order spirit plants that were short in stature couldn't even get sunlight out of so many spirit plants.

The same is true for Xiao Hei, and the flock of birds has also advanced to the second order, and each huge size, just a mountain, is not enough for them to toss.

Expand.

Lin Yi turned his gaze to the mountains behind him, and had a preliminary idea in his mind.

There are many mountains in BS City, and the Qifeng Mountain occupied by Lin Yi and the surrounding several disciple peaks are considered to be small among the many peaks, and the only advantage is that it is close to human habitation.

With the growth of strength, expansion has become an inevitable thing in the future.

Instead of rushing and panicking, it is better to plan early.

The expanded territory is not for the disciples, but for Lin Yi's own, and these areas will be used by Lin Yi to place the spiritual plants he planted and the domesticated beasts.

So confidentiality and security are the key considerations.

Thinking of this, Lin Yi looked up at the cloud and mist phantom array that enveloped the entire Aoki Sect and shook his head.

"The Cloud Mist Phantom Array was okay before, but now it is obviously unable to keep up with the pace."

After all, it is a low-level formation, it is good to be able to play a little trick effect, and the range of the formation is limited, once the height of the spirit plant is too high and breaks through the limit of the formation, the spirit plant will be completely exposed.

This was not the case before, but now there are a few spirit plants that do not grow in stature and only grow in height, and there is already this trend.

However, in response to this, Lin Yi did not have much hope for the formation.

He would not allow others to handle his own means of protection, and the basic operation of leaving the back door in the Great World of Cultivating Immortals had been deeply imprinted in his mind.

He is used to leaving some back doors, and there is a good chance that others will stay.

If the protective formation is left behind a little back door, and the person who leaves the back door can enter whenever he wants, what is the difference between it and a female college student who is being raised.

"It's best to have a few spirit plants that can obscure your vision and protect you."

Only spirit plants are Lin Yi's most trusted means, and almost all spirit plants, as long as they are controlled for the first time, leave their own mark on it.

The next Wood Energy Monk will no longer be able to easily control this spirit plant.

Usually, Lin Yi would not deliberately leave a mark, after all, they were all ordinary spirit plants, there was no need for this, he only left a mark on each carnivorous flower he sold, in case it was manipulated by others.

"Actually, the previous offensive spirit plant was good." Lin Yi suddenly thought of the bald old man who had outstanding performance in the cultivation conference.

This bald old man used the four words of core inheritance at that time to withstand the pressure of the Super Management Bureau, although he leaked the fact that the sect had an aggressive spiritual cultivation plan, but it also gave his own sect an additional source of income.

From the big sales of Lin Yi's carnivorous flowers, it can be seen how great the demand for offensive spirit plants in various fields of Huaguo is.

Thinking of this, Lin Yi sent a message to Ning Xiuyuan and asked him to contact the sect where the bald old man was located.

Try to trade first, first salute and then soldier.

It's best to be able to trade, and if you can't trade, try something else.

Lin Yi guessed that these people should agree to the exchange, and the trading chips he asked Ning Xiuyuan to report were not low, and there were also second-order plants.

I don't believe that I can't move these people.

Many things have their own value, even the core inheritance is the same, Lin Yi is not short of resources now, what is lacking is this special spiritual plant cultivation method.

Once he mastered it, he would be able to find a way to create a higher-level offensive spirit plant that would provide better protection for the various hills.

Ning Xiuyuan went to contact each other, and they added each other's contact information after the game.

Ning Xiuyuan, the champion, was added by almost all the participating spirit planters, and it was not uncommon to have the contact information of a bald old man.

Aggressive spirit plants can be solved from this way, but the spirit plants with a masking effect seem to be really hard to find.

Lin Yi took out his mobile phone and began to look through the exchange list of the Transcendent Alliance.

The number of items on the exchange list increases almost every day, and the type and number of items in the proximal time are significantly increasing compared to some time ago.

In the past, spiritual plants, pills, talismans and other things that were rarely seen in the past are now very frequent on the exchange platform.
