The boulder beneath him turned into a pile of debris, and Shang Xia's face was bitter, thinking that the next moment the column of water gushing out of the underground water mouth would wash away the pile of debris.

Unexpectedly, just as Shang Xia's eyes were wandering around, ready to find another such boulder, the imaginary scene of the water column rising into the sky did not happen.

Not only that, but even the water seeping out of the cracks in the stone appears to be very small.

Although Shang Xia didn't know what was going on in the underground veins just now, his intuition told him that the movement just now should have been caused by the fifth-order ancestor from the White Deer Blessed Land who had descended on Youzhou.

Although Shang Xia still didn't know how that fifth-order ancestor had descended on Youzhou, the obvious decrease in the flow of water in the underground veins was obviously related to this.

Shang Xia thought about it, and simply stopped looking for the boulder, but instead kicked away a pile of rubble pressed on the water inlet, and pulled out the water mouth buried underneath.

The flow of water gushing out of the mouth had indeed been greatly reduced, and it looked like the current was the same when Shang Xia first found the source of this stream.

Not only that, Shang Xia found that there was almost no more mist gushing out of the water gushing out of the water mouth.

Just when Shang Xia was pondering whether he should enter the underground water veins from here as agreed with You Yan before, suddenly a dull and distant loud noise came from the northern sky.

Hearing this, Shang Xia hurriedly turned his head to look at the northern sky, but he saw that a large area of glow suddenly rose in the sky above the sky, and then turned into a rainbow bridge of glow, continuing to stretch towards the end of the northern sky, until it disappeared into the void.

The place where the glow rose was obviously where Changfeng City was about.

And then the direction of the Xiaguang Hongqiao across is indeed the approximate direction where the city is located.

Not surprisingly, this should be the fifth-order ancestor who descended in Changfeng City, and he has continued to go north to Tongyou City.

Shang Xia thought about it, and did not immediately start to widen the water mouth on the ground, but for the sake of caution, he felt that he should wait a little longer.

After waiting for about half a stick of incense, there was no more major movement in the sky above the northern sky, but the glow rainbow bridge that probed into the direction of Tongyou City seemed to become more and more condensed at this time.

At this time, Shang Xia didn't know the right time to really dive into the underground water vein.

The fifth-order ancestor was able to make a huge movement in the sky above Changfeng City, but the fourth-order martial artist could not do it.

Therefore, Shang Xia didn't know that You Yan was studying in Changfeng City

When will he do it, therefore, the timing of his action can only rely entirely on his own speculation.

The thought in my heart flipped over, and finally I decided to widen this passage to the underground water vein first.

The Red Star Spear pierced directly into the underground water inlet, and then stirred it with all his might, and then the entire underground water mouth was suddenly widened in a circle, and at the same time, the crushed gravel and mud were all brought out as he pulled the Red Star Spear back.

After repeated repeats, the entire inlet was widened enough for one person to enter and exit, and the flow of water gushing out of the inlet became much larger, but there was no sign of a large-scale gushing.

After retracting the Red Star Spear, when Shang Xia was finally hesitating whether to dive into the underground veins now, suddenly the sky above the northern sky was bright.

When Shang Xia looked up, he saw that the Xiaguang Hongqiao had sunk into the void, and suddenly there was a chaotic aura surging back.

That aura that was so rich that it was like substance was not too unfamiliar to Shang Xia, because he had had a similar experience in the Two Realms War Domain, it was the unrecognizable color when the origin tide erupted, and the origin of heaven and earth emerged.

With the emergence of that chaotic aura, the Xiaguang Hongqiao seemed to have become a channel for the origin tide to flow, like a waterfall, it continued to fall from the void to the place where the Xiaguang Hongqiao rose, that is, Changfeng City!

Shang Xia looked at the distant sky with some surprise, and suddenly understood in his heart that the fifth-order ancestor of the White Deer Blessed Land had descended, probably to snatch the origin of the two realms that Tongyou Academy had received from the two realms battle domain.

That Xiaguang Hongqiao was the channel that the Fifth Order Ancestor used to connect the origin of the two realms through the air.

At the same time, the water vein under Changfeng City is probably not only used to lure the fifth-order ancestors to cross the border to descend on Youzhou, but also bears the key to sending the origin of the two realms seized from Tongyou Academy back to the Bailu Blessed Land in Jizhou!

As the stolen origin of the two realms above the sky fell towards Changfeng City, and then Gao Yunlai, who was left there, with the help of the formation arranged in the underground spirit cave, the underground water veins that had originally fallen began to rise gradually, and even Shang Xia noticed that in the widened water mouth, the groundwater that flowed out gently showed signs of upwelling.

At this time, Shang Xia knew that it was no further ado, and jumped towards the water mouth, and the true qi in the dantian sank downward, and the whole person sank all the way down the waterway.

Shang Xia didn't take out the water beads left for him by You Yan from the beginning, and after sinking three zhang from the water mouth, the clear bottom of the water was already able to let him see the source of the underground water vein

The head should be behind a rock crevice.

After taking out the water beads and discharging the water around him, Shang Xia drilled into the rock crevice from above, and jumped into a passage that was more than a zhang long and wide.

This underground river channel is obviously the main river channel of the underground water vein under Changfeng City.

Judging by the height of the water column on the ground, the current in this channel is not only turbulent, but also large enough to fill the entire underground channel.

However, the water level in the underground channel was only half full.

There was a cool chill flowing in the river channel that came out of the air, and when Shang Xia jumped into the water, although there were water-repellent beads to drain the water, the feeling of coldness and coldness could never be isolated.

The underground river channel does not know the direction, according to the previous speculation of Mr. Bu and You Yan, this underground water vein should cross the Chiba Mountain Range from north to south, which means that Shang Xia should now go upstream in the direction of the water flow, so that he can finally find the underground water vein spirit cave in Changfeng City along the water vein.

Without further ado, besides, this place is quite far away from Changfeng City, and Shang Xia is quickly tracing up the underground river.

Fortunately, the water beads can not only dispel the water around the body, but also accelerate the speed of travel under the water.

Although it was not as fast as Shang Xia's light body martial arts on the ground, there was no obstacle from the ups and downs of the mountainous terrain underground.

But even so, Shang Xia ran all the way along the underground river for half an hour, and it was still dark in front of him, but the water level of the underground water veins was gradually rising, and the amount of water was also much larger.

Shang Xia was anxious and couldn't help but speed up again.

But before he could walk a distance of three or five miles, in the underground channel where only the river flowed, suddenly there was a continuous low and dull sound from the upper reaches again, and the sound became closer and closer, so that the river under his feet trembled slightly.

Shang Xia was apprehensive in his heart, but he was in the underground river at this time, but there was no way to avoid it, so he could only simply lean over and sink to the bottom of the river, grasp the gap in the stone wall at the bottom of the river, and stick his body tightly against the bottom of the river.

It was too late to say that it was too fast, and at the moment when Shang Xia had just prepared, the roar that made the entire underground river tremble with it.

The imaginary turbulent torrent did not really arrive, but the space opened up by the water beads at the bottom of the river was greatly compressed, and the cool cold air became more and more abundant, but what really shocked Shang Xia was that the entire river at this time was filled with a rich Heaven and Earth Origin Vitality!
