The breeze was blowing, and beneath the huge formation, a vast lake shimmered in the sunlight, not the reflection of the lake surface, but a metallic glow reflected.

This kind of light was so dazzling that Shi Xiao couldn't even open his eyes, and even made Shi Xiao unable to believe it at all.

"What's that!?" Shi Xiao covered his eyes and looked at the extremely dazzling lake below, and said in surprise.

Tun Tong also had the same expression as Shi Xiao, and came out of his clothes, staring at him blankly.

"Lord... Master, it seems to be a domain stone...", he stammered.

Shi Xiao's whole body was for a while, urging the spiritual power to continue to rush downward, but this formation blocked the way, however, the power of the formation was about to dissipate, and under the impact of Shi Xiao's aura, it was also completely shattered.

At this moment, the surface of the lake that was not covered by the formation completely fell into Shi Xiao's eyes, this was a lake with an extremely metallic luster, like a lake made of some kind of metal.

The lake didn't have any breath, let alone any spiritual power fluctuations, if it weren't for this scale, it would be a swamp at all, and no one would pay attention to it.

But in fact, it is a lake made of domain stones, and the metallic liquid below is none other than domain stones, domain stones with extremely strong power.

Shi Xiao moved forward slowly, his throat was a little dry, and he slowly swallowed his saliva, approaching the stone lake.

How could he have seen such a scene, the domain stones are all stones or a high mountain, and how could such a liquid appearance appear.

"This place is full of domain stones, but it has been transformed by people with formations, and this kind of aura is much easier to absorb than the stone-like domain stones!" Tun Tun introduced, and he also slowly moved forward.

At this time, in its field of vision, on the surface of this lake, a thick breath surged, white and mellow, it was spiritual power.

Although it is extremely thick, several times more powerful than the ordinary spiritual power in the air, the scale is only about a few centimeters suspended on the surface of the lake, which is very shallow, and if it is not for the extremely powerful perception, it will not be felt at all.

Surrounded by mountains, although the scale of this domain stone lake is very huge, because of the previous obstacle of the blinding formation, its surface is a ruined place, and there is not the slightest fluctuation of spiritual power, so people who pass by will not pay attention to it at all.

"Domain Stone spiritual power of this scale... This breakthrough should be expected!" Shi Xiao said intermittently, extremely excited, clenched his fists.

Such a lake, which is all transformed by domain stones, and the spiritual power contained in it is probably not as good as the original domain stone mountain, which is great news for today's Shixiao.

Shi Xiao slowly approached the lake, urging the Ancestral Body Secret Method, and using it to guide the spiritual power below, and sure enough, at the moment when the Ancestral Body Secret Method was opened, a pure and thick spiritual power from the lake below suddenly began to gather towards him.

"Swallow, now we can make a lot of money!" Shi Xiao was about to jump up with excitement, and no matter how much the spiritual power of the domain stone of this scale below was absorbed, he was afraid that he would not be able to absorb it.

It was said that it was too late, and Shi Xiao immediately sat in the air, urging the ancestral body secret method to begin to absorb the spiritual power below, and at the same time, he unfolded the Vientiane soul vein and began to cultivate the spiritual energy.

This endless spiritual power poured into Shi Xiao's body in waves, nourishing that spiritual stack.

Now it is Shi Xiao who is in a bottleneck state, and the spirit stack in his body is also in a bottleneck state, although the cultivation speed is much faster after the previous ten spirit stacks are fused into a spirit stack, but the difficulty of his cultivation has also increased a lot.

In a spirit stack, the two forces of the Void Saint Spirit and the Boundary Source Pact Spirit were intertwined and fused, and with the infusion of external aura, the two also began to twist and rotate.

Since the two were fused into a spirit stack, from that time on, the manifestation of Shi Xiao's cultivation and cultivation was not the enhancement of spiritual energy, but the degree to which the two were fused in this spirit stack.

As long as Shi Xiao increases the degree of integration of the two, it corresponds to an increase in strength, not like ordinary cultivators, the manifestation of improving cultivation is the increase in the storage of spiritual energy and the enhancement of strength.

It was also because of this that Shi Xiao's cultivation speed was very obvious, but it was also because of this that his cultivation difficulty had also become huge.

If you want to fuse the two that can fight, the method is not as simple as saying it, you must know that when the Void Saint Spirit was gathered, it almost devoured the Boundary Source Pact Spirit.

Therefore, if you want to fuse the two, the workload is not ordinarily huge, and the scale of the aura required is also extremely huge.

The spiritual power was refined into an aura that urged the Realm Source Pact Spirit and the Void Saint Spirit, and the two were intertwined and fused in the spirit stack, but at this time, the speed of fusion between the two was extremely slow, or it was almost impossible to fuse.

And this is the bottleneck of Shi Xiao now, he has stepped into this situation long ago, no matter how he inputs the aura into it to promote the fusion of the two, but it is also slow.

At the beginning, all the spiritual power transformed by that level of domain stone had been absorbed by the two, but he had never seen the progress of the fusion, but now it was different, the spiritual power of this scale of domain stone, whatever he said, was enough for his cultivation.

Suspended in mid-air, the spiritual power below converged towards Shixiao at a speed visible to the naked eye, the speed was unhurried, and when it arrived at the body, it gradually transformed into spiritual energy, continuing to merge into the spiritual stack.

Everything was extremely ordinary, and the Realm Source Pact Spirit and the Void Saint Spirit in the Spirit Stack also began to operate under this urge, continuing to merge.

After a long time, Shi Xiao opened his eyes suddenly, frowned, and wondered: "Why is it as calm as ever after absorbing so much spiritual energy!?"

As he closed his eyes and opened them, another week passed, and in this week, all the time was injecting spiritual energy into the spirit stack, urging the two to merge, but the two were urged, and there was no sign of merging at all.

Shi Xiao let out a long breath of turbid air, and the swallow on the side also woke up in the state of absorbing spiritual power, and the seven-colored divine aura behind him twisted and gradually retracted, and the seven-colored light also slowly disappeared from the periphery of Shi Xiao's body.

"Master, I can't help it..."

Tun Tun is also a little disappointed, when Shi Xiao enters the cultivation state, it also urges the aura, adjusts the aura of Shi Xiao to the best state, and the vitality is also nourishing Shi Xiao's body all the time, so that it can absorb spiritual power in the best state.

But even so, Shi Xiao's state had been adjusted to the best, and the speed of absorbing and transforming spiritual power was extremely fast, but he still couldn't complete the fusion of the Void Saint Spirit and the Realm Source Pact Spirit.

Shi Xiao looked at the huge scale of the domain stone below and felt extremely uncalm in his heart, such a cultivation had no progress at all, and he was even a little disappointed.

"It's my approach that's wrong... Or are the two inherently incompatible..."
