If Liu Chengfeng can really be taken in by Xia Ruofei for his own use, not to mention anything else, just his cultivation at the 7th level of Qi refining is already a lot higher than Li Yifu.

The people around Xia Ruofei, Tang Haoran, a disciple of his own family, are still young, and his cultivation is also very low. And Ling Qingxue and Song Wei's cultivation had only reached the 3rd layer of Qi refining, even if they were able to break through to the 4th layer of Qi refining immediately, they were still a lot worse than Liu Chengfeng.

What's more, Liu Chengfeng is also very familiar with the affairs of the cultivation world, and he also has the identity of a disciple of the Fallen Leaf Sect, which is quite helpful for Xia Ruofei to contact the cultivation world in the future.

If Liu Chengfeng can be completely subdued, it will be equivalent to planting a shadow in the Fallen Leaf Sect, and it may be able to play an unexpected role at a critical moment.

Of course, the premise of all this is that he can really subdue Liu Chengfeng completely, and there is nothing he can do for the time being.

If Xia Ruofei was really a cultivator in the Yuan Infant Stage, it would be easy to do, but the problem is that now his cultivation is only a little higher than Liu Chengfeng, and Liu Chengfeng already knows some of the secrets of the Spirit Map Space, even if he doesn't know that this is an independent small space, but just a cave with an extremely rich spiritual energy is enough to shake the cultivation world. Therefore, it is impossible for Xia Ruofei to risk sending Liu Chengfeng out at this time.

Of course, if Xia Ruofei really had the cultivation of the Yuan Infant Stage, there would be no need to arrange any shadows, and he would be able to destroy the Fallen Leaf Sect with a wave of his hand.

In short, Xia Ruofei didn't want to leave hidden dangers, and at the same time held the hope of being able to subdue Liu Chengfeng, so he didn't kill him on the spot, but put him into the Lingtu space.

It's just that there is nothing to do for the time being, so Xia Ruofei can only keep Liu Chengfeng in captivity first.

In an instant, Xia Ruofei came to the large space cage where the killers and mercenaries were imprisoned.

With a wave of his hand, the two spatial cages disappeared directly.

One or two hundred screamed and fell from the sky.

Xia Ruofei easily invoked the invisible power of space and lifted these people up when they were about to fall to the ground.

Then he casually demonstrated what seemed like a miracle in these "crooked nuts", and easily dissuaded the men from resisting.

Including the unruly Douglas, the leader of the Mod Mercenary Regiment, were all frightened by the methods displayed by Xia Ruofei, the "Oriental Immortal".

No matter how powerful the special forces are, can they defeat the "immortals" who fly away from the sky?

What's more, these days have been imprisoned in the space cage, and the spiritual will of these people has long been consumed very weakly, coupled with Bao Guijun, Golden Fox Melendo, Viper Boak and others "showing up", these killers and mercenaries were quickly absorbed.

Manzira, nicknamed Satan, failed to play a role in the process of co-optation.

Because his identity is not clear to the other Mod leaders except for Boac, Douglas only knows that the boss's nickname is Satan.

These killers and mercenaries were also scattered and assigned to various groups, and there were many more people under Bao Guijun and others.

Xia Ruofei simply allowed them to add a leadership level, divided each group into three squads, and asked Bao Guijun's team leaders to select three squad leaders to be responsible for each team and assist them in management.

The squad leader also enjoys a certain amount of base point bonus.

Bao Guijun and others were naturally overjoyed, there were more soldiers under them, and they could also have a certain amount of "personnel rights", and they could naturally be more handy in management.

In addition to not having freedom, Bao Guijun, Qian Guiyou and others feel more and more that it is actually quite good here.

There is no harm without contrast.

Similarly, it is precisely because of the comparison that Bao Guijun and the others feel that they are at least better off than most of the captives, and their hearts are suddenly much more balanced.

They even feel that being caught in the middle of a mission in China is not necessarily a bad thing.

At least they "got a head start" when it came to being free laborers.

After quickly absorbing this group of captives, Xia Ruofei gave them an hour.

Grouping, detachment, registration, dormitory, collection of labor tools and basic living materials, etc., these tasks do not need Xia Ruofei to manage, with Xia Qing in the space, Bao Guijun and others can naturally arrange it in an orderly manner.

Xia Ruofei left the space and returned to the outside world, resting in the bedroom for a while.

The time has not yet reached an hour, and it will only be more than forty minutes at most, Xia Ruofei received Xia Qing's heart-to-heart transmission, and this batch of free laborers has been properly settled.

So Xia Ruofei thought about it and re-entered the space.

Xia Ruofei stood in the void, as if a god had descended, his voice was not loud, but it clearly reached everyone's ears: "Today's labor is suspended, everyone will return to their rooms immediately, and they are not allowed to come out until they receive a notice!"

In this space, Xia Ruofei's words are undoubtedly willing.

With the order, all the laborers, under the leadership of the team leaders who took up their new posts, withdrew from the rice fields, medicine gardens and other places in an orderly manner, and all returned to stay in the prefabricated houses.

They didn't know what was going on, and they couldn't help but feel a little apprehensive, especially those laborers who had been living in the space for a while, and it was the first time they had encountered such a situation.

Xia Ruofei didn't explain too much, and directly strengthened the space cage shrouded in the outside of the prefabricated house several times, and shielded the space cage, and the membrane wall of the cage also changed from transparent to milky white, completely isolating the line of sight from inside to outside.

Then, Xia Ruofei moved the space cage that imprisoned Liu Chengfeng to the side of the prefabricated house, and also strengthened the space cage to a certain extent.

Xia Ruofei did this, naturally in preparation for the Lingtu Space to absorb boundary stones.

This time, the boundary stone is the size of a whole basin, and it is possible to evolve and upgrade again after the Spirit Picture Scroll completely absorbs it.

In order to prevent chaos in the process of space upgrading, Xia Ruofei summoned everyone back to the prefabricated room in advance, and specially reinforced the space cage.

Then, Xia Ruofei called out Xia Qing and Bai Qingqing again, telling them that the Spirit Map Space would absorb the Boundary Stone again, which might cause the space to upgrade at that time, and let them keep quiet and pay close attention throughout the process.

He especially warned Bai Qingqing, asking it to never make any moths in the process, otherwise it would be unkind to it.

Xia Ruofei instructed Xia Qing again to look at Bai Qingqing.

In this Lingtu space, Xia Qing has the highest authority except for Xia Ruofei, and he can also mobilize the invisible power of the space, if Bai Qingqing really makes trouble, Xia Qing will still be able to subdue it.

Bai Qingqing protested a few words dissatisfiedly.

Mainly because of this harvest, Xia Ruofei didn't give it a share at all.

Of course, this is also because in the process of obtaining the boundary stone, Bai Qingqing did not play any role. In addition, the boundary stone obtained this time is a whole large piece, if it is a small boundary stone cut into a standard size as in the past, under the condition of ensuring that the space can be upgraded, Xia Ruofei does not mind giving Bai Qingqing a few pieces.

Bai Qingqing's protest was naturally ineffective.

After all the orders were given, Xia Ruofei left the space in a flash.

Back in the courtyard bedroom of the outside world, Xia Ruofei used his mind to establish a connection with the Lingtu Scroll, and at the same time, he also removed the shielding and protection from the huge boundary stone that had been stored in the Yuan Chu Realm, and gave the Lingtu space an order to absorb the boundary stone.

Xia Ruofei could feel that the entire Lingtu space seemed to be conscious, conveying a cheering emotion, and then a suction force suddenly appeared, and the huge boundary stone suddenly suspended in the void.

The mysterious spatial energy in the boundary stone was also quickly absorbed by the spirit map scroll.

Xia Ruofei had been nervously following the whole process, and secretly prayed in his heart, hoping that this time the Lingtu space could be successfully upgraded.

The acquisition of boundary stones is often difficult to meet, if you can't upgrade after absorbing all the boundary stones this time, then you don't know when to get the boundary stones next time.

And the Lingtu space has evolved to this extent, if you only rely on absorbing jade materials to replenish it, the demand will be incomparably huge, even if Xia Ruofei has abundant funds, but the jade materials on the earth are also limited, not that if you have money, you will definitely be able to buy enough jade materials.

What's more, such a large-scale purchase of jade raw materials without engaging in any jade business will definitely arouse the idea of people with intentions.

Therefore, after experiencing several spatial upgrades, Xia Ruofei basically gave up the idea of using jade materials to "feed" the Lingtu space.

That boundary stone was very large, and it took a long time for the spirit map space to absorb it, and it only then did it lighten its color slightly, and at the same time, one or two subtle cracks occasionally appeared on its appearance.

Xia Ruofei had already experienced such a process many times, so he knew very well in his heart that the mysterious energy contained in this boundary stone was far from being absorbed.

He couldn't help but be full of anticipation in his heart, the more "strong" the performance of this boundary stone, the greater the possibility of direct upgrading after the spirit map space was absorbed.

The process of absorption is relatively long, but Xia Ruofei is not impatient at all, and even hopes that the longer the process, the better.

More than two hours passed, and the color of the basin-sized boundary stone became lighter and lighter, and there were more and more cracks, covering almost the entire surface of the boundary stone.

Xia Ruofei knew that the energy contained in the boundary stone had been almost consumed.

However, there was still no sign of upgrading in the Lingtu space, and Xia Ruofei couldn't help but feel a little secretly anxious in his heart.

At this time, the appearance of the boundary stone was already grayish-white, and from time to time there was a slight clicking sound, accompanied by small pieces of stone chips constantly peeling off from it, and it was obvious that the energy was about to run out.

Xia Ruofei sat on the bed in the bedroom with an anxious face, keeping in touch with the space and sensing the situation in the space at any time.

Disappointment grew.

Seeing that the boundary stone had begun to fall apart, Xia Ruofei sighed secretly, it seemed that this wish to upgrade the space might be in vain.

However, just as the entire boundary stone completely shattered into small pieces and fell down one after another, the Spirit Atlas Space absorbed the last wisp of energy in the boundary stone. Immediately afterwards, the entire space shook slightly, and even Xia Ruofei's mind was shaken.

Xia Ruofei's mood was like a roller coaster, all the loss was swept away, and his face showed a look of overjoy, this feeling was too familiar to him, every time the spirit map space was upgraded, he would experience similar shocks. And this time, it seems that the shock is particularly strong.

Xia Ruofei immediately felt that the entire Lingtu space seemed to be trembling slightly, and immediately his mental connection with the Lingtu space was also affected, although it was not completely severed, but it seemed looming, and he couldn't perceive the situation in the space so clearly.

Xia Ruofei simply retracted his thoughts and sat in the bedroom waiting.

The process of waiting, time always passes slowly.

Xia Ruofei was anxious and expectant, and after a while, he couldn't help but use his heart to establish contact with the Lingtu space. However, the process of this upgrade seems to be particularly long, a full two hours, and the connection between Xia Ruofei's mind and the space is still bright and dark, which shows that the upgrade of the space is still in progress.

Later, Wu Qiang went outside to ask Xia Ruofei to have dinner, but the spirit picture scroll could not be included in the body during the upgrade process, and Xia Ruofei naturally didn't worry about putting the spirit picture scroll in the bedroom, so he told Wu Qiang that he was not hungry and didn't eat dinner.

In fact, Xia Ruofei was not in the mood to eat now, and all his thoughts were on the Lingtu space.

It wasn't until around ten o'clock in the evening that Xia Ruofei re-established a mental connection with the Lingtu Space.

This shows that the Spirit Picture Scroll has completed the process of this upgrade.

Calculating the time, this upgrade actually took six or seven hours, which is several times more than the last one.

This also made Xia Ruofei have more expectations in his heart.

When he re-established a mental connection with the Lingtu space, his first feeling was that this connection was much clearer than before.

It's as if a normal screen has suddenly been replaced by a 4K HD screen.

Before entering the space, Xia Ruofei first noticed a very obvious change.

Maybe it was the closer connection between the mind and the mind, or the changes that occurred after the upgrade of the Spirit Picture Scroll, Xia Ruofei found that he seemed to be able to control the appearance and shape of the Spirit Picture Scroll.

Naturally, no one would tell Xia Ruofei about this, but he just felt like this.

Xia Ruofei immediately gave it a try.

Sure enough, with just a thought in his mind, the spirit picture scroll actually began to shrink under his nose, and in the blink of an eye, it changed from a normal-sized ancient painting scroll to a pocket-sized scroll that was only a few centimeters long and could be held directly in the palm of his hand.

You must know that since Xia Ruofei got the Lingtu Picture Scroll, the Picture Scroll has always been this quaint appearance, even if he was able to put the Picture Scroll into his body later, but he did not change the appearance of the Picture Scroll, every time he took it out of his palm, the Picture Scroll was still the same as it was.

This change made Xia Ruofei very interested, and he was immediately not satisfied with just changing the size, so he began to try to change the spirit map scroll into something else.
