Fengqi has four major city gates, among which the Golden Horse Gate in the south is the most easy to defend and difficult to attack, and one of them benefits from the moat that is about several zhang wide and deep.

The moat of the Golden Horse Gate is different from the other three moats, and this river has existed since the establishment of the Golden Horse Gate. Xu Xiayi chose to do something in the Golden Horse Gate, it was also a fancy to the other three city gates are easier to break than the Golden Horse Gate, as long as the Golden Horse Gate is broken, it is only a matter of time before the other three city gates are broken under the internal and external echoes, and then the Ziyang Palace will be the turtle in the urn.

Xu Lai only thought for a few breaths, and then plunged headlong.

At the beginning, the icy river water in the cold winter stimulated his scalp like a needle, and he did not choose to use his true qi to drain the water. It's just that it's a little colder up there, and at the depths, the problem in the water is much warmer than outside.

Xu Lai spread his senses, and soon found the figure of the sea relics not far away. True Qi stirred behind him and formed a long undercurrent, and Xu Lai immediately followed.

Only by slashing the sea relics in his hands, or seeing with his own eyes that the sea relics pearls are really dead, can he feel at ease.

The speed at which both of them sank was extremely fast, and they sank to a depth of several zhang in an instant. As soon as they went down, the pressure increased significantly, and the speed of the two of them slowed down significantly.

These are not the biggest problems.

In the deep water, there is no sunlight at all, and nothing can be seen. By this point, visibility is almost the same as not seeing five fingers. If you can still use your divine sense to perceive it on the shore, but at this time, you are subject to the current of water, and the distance of your divine consciousness is less than one, but the consumption amplitude is multiplied.

But there is a benefit.

As we go deeper, the temperature gradually rises, and the water temperature is already within the acceptable range of a normal person. Even though his vision was blocked, Xu Lai could still roughly capture the direction of the pearl, but after sinking for a while, he felt that something was wrong.

The depth here, about 100 zhang underwater, has completely lost its light, and the pressure in all directions is much greater than on the shore, if you don't use the True Qi to protect your body, even with the body of a cultivator in the One Realm Realm, I am afraid that the tendons will be broken and broken by the current of the water, and you will be seriously injured.

The problem is in temperature.

Xu Lai had never been here, but he also knew that when the underwater depth reached a certain range, the temperature would be roughly constant at about a value. At a depth of about 100 zhang at this time, the temperature is still rising, which is completely unreasonable.

At this time, the squeezing of the water in all directions made him need to use a lot of strength to resist those currents to ensure that he was not harmed, coupled with the strangeness here, he naturally neglected to hunt down the sea pearl.

After half a cup of tea, Xu Lai had completely lost the position of the pearl of the sea.

At this depth, he was completely intentional and powerless, and he could even roughly guess which direction the sea relics were in, but he couldn't free up his hands to lock his specific location. The tremendous pressure of the water flow consumed most of his true qi, and at this time, the speed could not be raised at all, and he had to figure out what the reason for the temperature that was rising all the time.

The temperature and pressure were still within the range he could bear, but the speed and vision problems made him feel a little tricky. After roughly calculating the time when his true qi was exhausted, Xu Lai came to a conclusion that he could dive another three hundred zhang.

This is the limit of his diving, if he dives deeper, he may become the first cultivator in the history of the cultivation world to be squeezed to death by the current because he is unable to absorb true qi and his physical strength is insufficient.

At this time, Xu Lai's focus has faintly shifted from the sea relics to this moat.

It was so deep, so deep that it was completely beyond the depth of a "river".

Xu Lai changed his original posture of using his true qi to break through the water flow and sink, and transformed into a fish, swimming in the water on all fours. Although the speed of progress is also not fast, it can save him a lot of true energy.

After going on like this for half an hour, the temperature became higher and higher, and beads of sweat began to overflow on his forehead, and he already had to separate a trace of true qi to resist the heat here.

An hour later, the big man behind Xu Lai was drenched, and the excessive temperature made it a little difficult for him to breathe. There seemed to be a glimmer of light in front of me, but I still couldn't see anything.

Xu Lai's face became more and more solemn, according to his estimate, there was a distance of more than two hundred zhang at this time, although the moat was very deep, it was not very wide, and there was only one direction up and down.

There is nowhere else to go except to continue diving.

Just when he was thinking about whether to turn back, his body that had been diving suddenly paused, and his toes clicked a little, as if he had stepped on something. Xu Lai confirmed it again, bent down, and touched it with both hands, but it quickly bounced back.

In the end.

It is the sand and earth of the "river bottom".

It's just that the temperature doesn't look like the bottom of the river at all, it's more like a red-hot soldering iron, and the flesh of a cultivator in the One Realm feels a tingling pain to the touch, just in the blink of an eye, Xu Lai estimates that his palm has been slightly burned.

So he made a decision.

He stepped back some distance, Zhan Lu's sword was poured with a large amount of true qi, and Zhan Lu flew towards the bottom of the water with the buzzing of the blade, only to hear a muffled sound, like the muffled sound of a watermelon bursting when it fell, and with the splash of sand and dust in the sky, it finally suddenly became clear.

Everywhere you look, it's red.

Hundreds of feet underwater, there is a hole in the sky.

As soon as the water came into contact with the lava underground, only bursts of white smoke came out, and the pungent smell continued to come out, and the lava cooled rapidly, forming a lava island centered on the place where the water fell.

Xu Lai used the Zhan Lu sword to expand the gap by another point, and the power of Zhan Lu under the water of hundreds of zhang was greatly reduced, and these movements he did were extremely slow, which consumed a lot of tea. When the entrance of the cave was enough for one person to pass through, Xu Lai leaned forward, only to feel a wave of heat rushing towards his face, even if he retreated quickly, his hair was also burned a little.

It's incredible.

Xu Lai had a true qi shield in his hand, and just the heat wave from the lava could scorch his hair. If you fall into it, won't you be shattered?

Ordinary lava can indeed kill cultivators in the One Realm, but when the True Qi is exhausted, it is like the continuous squeezing of water. If you just fall into the lava and then fly out, it's probably not a big deal. How could there be such an unusual lava under this moat?

After only hesitating for a few breaths, Xu Lai decided to go in and have a look.

At this time, the life and death of the Sea Relic Pearl was not so important, and the feeling of lava at the bottom of the river here reminded him of the Nine Heavens Flame in Sword Casting City, which may not be as good as the Nine Heavens Flame Flame, but with the help of the high temperature here, it is unknown that he may be able to re-temper the Fish Intestine Sword.

So Xu Lai slid into the gap that the Zhan Lu Sword had broken, and as soon as his body reached in, the heat wave on his face seemed to drown him. Luckily, it's not like an ocean with no foothold at all, but more like an underground volcano.

The place where the water fell had solidified the lava, and it had formed a large lava island, and Xu Lai descended with his sword, stepping on the Zhan Lu sword with both feet. Even so, the temperature of the soles of his feet was rising rapidly, and the heat had scorched the soles of his shoes.

Resisting those heat waves already required a lot of his true qi, and if he divided his mind to volley again, he was afraid that he wouldn't be able to last much time.

He just looked at it and estimated the nearest lava island to him, which was hundreds of feet away. The island was much bigger, and it looked like it had frozen for a long time, and the temperature should not be as high as this, but it would obviously be a bit presumptuous to go there directly.

So Xu Lai took out the fish intestine sword and planned to try it here now.

The furnaces of heaven and earth are all made of multicolored divine stones, and only the multicolored divine stones can withstand the high temperature of the nine heavenly flames in the furnace. The fish intestine sword forged in this situation, he was not sure if the lava here could be compared to the Nine Heavens Flame Flame, but he thought that as long as the fish intestine sword could be fused into one, it should be able to be used for the time being.

The rest of the matter can only be discussed when he goes to Sword Forge City in the future.

After using his divine sense to manipulate the Fish Intestine Sword and quench it into the lava, Xu Lai could hardly perceive the changes in the Fish Intestine Sword because the Fish Intestine had lost most of its spirituality. After a few moments, the Fish Gut Sword surfaced to the lava, and the two broken sections did not change at all.

Not even the high temperature here? The Nine Heavens Flame has such magical powers?

Xu Lai didn't want to give up again, so he stepped on the Zhan Lu Sword with both feet again, and headed towards the lava island closest to him. After walking three or five zhang away, Xu Lai found that the truth was exactly the opposite of what he imagined, and the temperature here was even higher than that of Fang Cai.

And as he continued to go deeper, the temperature seemed to be getting higher and higher.

Is this worth it?

When he arrived at this lava island, Xu Lai's back was already sweating, and his clothes were wet with sweat, and then they quickly volatilized and were dried raw. Xu Lai dipped the fish intestine sword into it again, and took it out after a while, only to find that there was still no change in the slightest.

This result made his brow furrow deep, and it also made him retreat for the first time.

With his current strength, it is already extremely dangerous to go deep here, and if he continues to go deeper, the temperature continues to increase, then it is not a sword that has gone sideways.

However, thinking that the Sea Relic Pearl still hadn't been found, Xu Lai was still a little unwilling, so he planned to try again, he had been running in with the fish intestine sword for a long time, and it was better than only having a Zhan Lu sword to use.

Maybe it's not taking long enough to quench?

After immersing the fish intestine sword, Xu Lai separated a part of his true qi and discharged the surrounding lava, this action made his forehead sweat even worse, and beads of sweat dripped down. I don't know how long it has been, whether the fish intestine sword has changed He doesn't know, a hollow, lonely but extremely desolate voice came out.

"It's useless. ”
