"This Source Space consumed so many resources when it was built, one hundred trillion units of crystal energy, ten trillion units of star wood and star stones, and one trillion units of star mother mercury, star core crystal, moon shadow sulfur, and solar gem, I didn't expect it to be so big in the end, it's incredible, where did so many resources go?" Ye Yifan's heart at this time could be said to be full of doubts and puzzles, but no matter what he thought, he couldn't figure out the reason, so in desperation, he had no choice but to give up!

"By the way, since the Source Space is a brand new space, can it also grow?Otherwise, there is only such a small area, why can it be called a space?" Suddenly, Ye Yifan thought of a possibility.

"In that case, can the Source Space continue to grow by absorbing crystal energy or other resources?"

As soon as he thought of this, Ye Yifan immediately took action, and he quickly divided a batch of resources according to the proportion of resources consumed in the previous construction of the Source Space, and tried to send them into the Source Space.

"Whoosh!"

Originally, Ye Yifan thought that this kind of attempt would be difficult to succeed and would have to be continued many times, but when he had just mobilized some resources from the castle in his mind and tried to send them into the Source Space, he found that those resources disappeared all of a sudden.

"Is this a success?" Ye Yifan was a little unconvinced at this point at first, but when he sank his mind into the Source Space, he found that those resources were really included in it and were placed in the central area of the Source Space!

"Uh! Looks like that's true!"

Speaking of which, Ye Yifan has an unparalleled sense of control over the Source Space, it seems that he is completely able to control everything in this space, no matter what he wants to do, he only needs one thought! Ye Yifan didn't have any special feelings at first, but after he reacted, he realized that maybe this Source Space was really useful!

Of course, the premise is that Ye Yifan can "raise" the space of the source, otherwise, with the current area, it is really not enough!

"Huh, why hasn't it changed?" Although it was easy to send the first batch of resources into the Source Space, how to nurture them and grow them up became a new problem.

Originally, Ye Yifan thought that as long as he sent resources into the source space, the latter would absorb them on his own and slowly expand his territory. But now it seems that this is not the case at all, as if there are some unfulfilled conditions here!

"Let's see if there's a lack of other resources. And...... Organisms?" When Ye Yifan used resources to fill the Source Space, the latter still did not change! But fortunately, as long as Ye Yifan had a thought, the materials in the Source Space would be taken out.

In this case, Ye Yifan thought of another possibility.

"Buzz!"

Followed by. Ye Yifan quickly took out some strange beast corpses from the backpack space and sent them into the source space, along with several treasures. And just when Ye Yifan had just completed this attempt. I found that the treasures that had just been sent into the Source Space actually flew up. Floating in mid-air, shining with white light, the corpse of the alien beast on the ground began to slowly dissolve, and then the various resources on the side began to disappear little by little.

"Haha, it's done!" At this time, Ye Yifan was keenly aware that this source space was actually slowly growing. See this scene. Ye Yifan immediately understood that his attempt should have been successful, and he had found the conditions for the space of the source of cultivation.

"Try this again!"

Immediately after, Ye Yifan tried to send a giant dragon corpse into the source space.

"Well, the expansion speed of the Source Space has really accelerated. It seems that these creature corpses are the catalyst for the growth of the Source Space, which can help it absorb all kinds of resources and complete its expansion!But what are those treasures for? Let's try again!" Ye Yifan quickly made a judgment.

After figuring out the effect of the alien beast corpse on the source space, Ye Yifan waited patiently until the few low-level treasures in the source space and all the alien beast corpses, including the giant dragon corpse, disappeared, and then released another treasure and sent it in.

This time, there were only all kinds of resources and a low-level treasure in the Source Space, and there were no alien beast corpses.

"Uh, it seems that it still won't work without the corpse of a strange beast!" After waiting for a long time, he didn't see any changes in the treasure and various resources on the ground, and at the same time, the space of the source also no longer changed after growing to a radius of almost hundreds of meters, Ye Yifan was basically sure that the corpse of the creature was indispensable in the process of cultivating the space of the source!

Then, Ye Yifan tried again, he took out the treasure and sent it into a strange beast corpse.

"Sure enough!" Looking at the ever-growing Source Space, Ye Yifan couldn't help but cry out excitedly.

At this point, Ye Yifan had completely figured out the conditions of the space of the source of cultivation. Among them, the corpse of a creature is indispensable, that is, a necessary condition, and a treasure is dispensable, but once there is a treasure, it will greatly accelerate the growth rate of the source space.

In this respect, neither the corpse nor the treasure can be considered a catalyst in the usual sense, as they will disappear as the source space grows, which does not meet the definition of a catalyst.

But no matter what, Ye Yifan felt very lucky, because he had all kinds of resources needed for the space of the source of cultivation, and the number was very sufficient, and at the same time, there were many treasures and corpses of alien beasts Ye Yifan's backpack space was also prepared, and even filled with the backpack space of many heroes, especially the corpses of alien beasts, since Xiaohuang grew up, Ye Yifan has not found a better use for these corpses, plus he is also relatively busy and has no time to pay attention to it, so he has been backlogged in the backpack space, which is just in handy at this time, and there is no need to worry about the lack of corpses of alien beasts。

After finding something to do, time flies, and the main thing Ye Yifan does every day is to "feed" his newly obtained source space.

What made Ye Yifan excited was that with his later attempts, the "appetite" of the Source Space was unexpectedly good, there was almost nothing it didn't "eat", no matter what Ye Yifan put into it, it would eventually be melted and absorbed, and then let the Source Space grow!

There are even some living creatures here, such as the embodied soldiers under Ye Yifan's command.

However, the process of "digestion" of these living creatures in the Source Space is very different from other things, and other things, including resources and treasures, as well as the corpses of living creatures, are constantly dissolving after being put into the Source Space, and eventually disappear completely, turning into a part of the Source Space. And these embodied soldiers are only decreasing in vitality, and they are not directly dissolving.

Seeing this, Ye Yifan specially left a few embodied soldiers to try, and he found that when the vitality of these embodied soldiers was exhausted, they would quickly dissolve, and finally disappear without a trace.

It can be seen that the process of decreasing life force is actually the process of ablation.

And those embodied soldiers who were recovered by Ye Yifan in advance will completely recover their lost vitality when the next day comes.

"It seems that there are still loopholes to be drilled here, since this is the case, then there is no need to test again, and directly cultivate the source space in the most perfect and fast way!" After determining the impact of all these factors on the source space, Ye Yifan immediately sped up his speed and sent batches of resources into the source space, making it grow rapidly.

I have to say that Ye Yifan's attempt to send the embodied soldiers under his command into the Source Space is still quite effective, at least increasing the growth rate of the Source Space by ten times, so that the Source Space can grow faster!

In fact, being able to think of this, Ye Yifan was still inspired by the special space of the giant dragon before, and at that time he found that the vitality of himself and the soldiers under his command was declining, only the puppet soldiers were not affected, and the vitality absorbed by the special space could be transformed into rat monsters, which also left a very deep impression on Ye Yifan!

But fortunately, he had that experience, otherwise Ye Yifan didn't know how long it would take for Ye Yifan to dig out this shortcut to the space of the source of cultivation, maybe he wouldn't find out until the space of the source grew up!

Because the various resources prepared by Ye Yifan, as well as the treasures, the corpses of alien beasts and other items needed for the space that contains the source are very sufficient, and they have not been interrupted at all, so the growth rate of the original source space is extremely fast, and it didn't take long to expand to a radius of more than a kilometer, almost an irregular circle with a diameter of two kilometers, to be precise, it is an irregular square, but this is not important, the important thing is that at this time, the expansion speed of the source space has slowed down, and it can expand by about five percent per day on average!

And when the source space expanded to a radius of about 100 kilometers, its expansion rate decreased again, and only about one percent of the daily expansion rate remained!

However, when Ye Yifan began to send the embodied soldiers under his command into the Source Space to provide them with surplus vitality, the latter's expansion speed increased again, reaching an area of about ten percent per day.

Of course, there is also a premise, that is, the soldiers under Ye Yifan's command must fill the source space station and replace it in real time, so that the source space can absorb a huge amount of surplus vitality without any interval.

But this is nothing to Ye Yifan, the number of soldiers under his command is extremely amazing, and he can fully afford it!

......

Time passed slowly, and since he obtained the source space, Ye Yifan also temporarily gave up continuing to enter the next dragon country, but quietly returned to the earth, stayed with Lan Ruolin and the others, and lived a semi-secluded life.

The so-called semi-secluded life is that although Ye Yifan does not deliberately avoid the attention of others, he does not show up specifically, and as time goes by, Ye Tian gradually grows up, especially after entering high school, he can already be on his own, after all these years of training, even if Ye Yifan no longer interferes, Ye Tian can manage the entire earth civilization in an orderly manner, and then basically control the Earth Federation in his hands!

In this case, everyone's attention was attracted to Ye Tian, and for Ye Yifan, an "old" person, the attention was not so high! (To be continued......)
