The temperature under the water is not as low as Xia Mingdao imagined, it should be said that there is no difference from reality, the clothes on his body have been completely soaked in the water at the moment, but even so, Xia Mingdao, who is familiar with the water nature, has not been hindered in any way, and continues to dive, searching for the cave that Bai Gu said.

Because of the support of spiritual power, Xia Mingdao's underwater breath-holding time is much longer than that of ordinary scuba swimmers, so Xia Mingdao is not worried about time at all, he is very careful with every step now, not only because he is afraid that he will miss the cave, but also because he is paying attention to the elves with great power that Bai Gu said.

As Xia Mingdao expected, the lake here contains more spiritual power than the outside, but the territory here is quite chaotic and cannot be used, and in fact, in addition to proper rest and daily diet, the spiritual master does not have too many other ways to replenish spiritual power, let alone those means to absorb external spiritual power, spiritual power is the same as blood, and it doesn't matter if it is safe to absorb the consequences directly, a large part of it is to make himself embarrassed.

However, because of the abundance of spiritual power here, the strange spiritual power loss rate in Xia Mingdao's body has also been curbed, which makes him not have to worry about whether he will lose his ability to protect himself due to the depletion of spiritual power.

There are no familiar creatures under the water, it should be said that there are no creatures visible to the naked eye, not a single fish or shrimp can be seen in the vast water of the lake, only dense gloomy algae, and some things that are floating in the water like kelp, and the lake here is surprisingly consistent, mysterious, and lifeless.

After walking forward for a short time, Xia Mingdao saw the two stone pillars that Bai Gu said, the stone pillars looked like they should be artificially made, and they were put down after they were made, because one of the stone pillars didn't seem to be so stable.

In the middle of the stone pillar is a cave with a forty-five degree inclination, the cave is pitch black, and it is impossible to see what exists inside, Xia Mingdao hesitated when he was about to enter, and then turned around and floated to the surface of the water, changing his breath.

I don't know what is inside, if that white bone has the intention to frame himself, it is better to be prepared, even if that guy really wants to help, but I don't know what is in it.

Didn't Luo Yu say that it is impossible to get the treasure without seeing the boss, even so, he will chase you at the hand you are about to leave, this is the rule of the game.

After ventilating, Xia Mingdao dived into the water again, the cave was directly below him, this time after seeing the two stone pillars, Xia Mingdao did not hesitate at all, and swam directly into the cave.

Swimming into the cave, there is a long passage inside, but everything has changed here, the semi-circular tunnel is clearly carefully repaired, and you can see that the surrounding walls are very neatly planned, and there are a large number of frescoes scattered all over the passage, like an ordinary corridor of a rich family.

However, even if he had doubts, Xia Mingdao did not stop too much here, passed directly through the passage, and swam inside.

After passing through a long passage, Xia Mingdao finally saw a little light in front of him, which seemed to prove that the front was the destination he was asking to reach.

Wait, the light? Xia Mingdao's brows furrowed suddenly, this is underwater, how can there be bright light? When I was just in the passage, only the outermost mural could see the tip of the iceberg, and then it was pitch black inside, Xia Mingdao came in by touching the wall with his hand, and it should be darker inside, why is there a bright light?

Could it be that there is someone in front of you...... No, those elves are inside?

Thinking of this, Xia Mingdao immediately put his speed to the fullest, and moved over little by little, until he reached the entrance of the cave that emitted bright light.

Poking his head out of the cave and looking inside, Xia Mingdao's eyes instantly widened, and his face was full of shock.

I saw that there was another vast space inside, and several tall statues were placed there one after another, with different expressions and dresses, lifelike, but on the surrounding walls, there was something similar to a lamp, and the faint blue fire light jumped, illuminating this dark area.

Xia Mingdao swam out of the hole, approaching the unknown objects that were shining with blue light, and when he got closer, he found that it was indeed similar to a flame, but he couldn't touch it, and when he reached over, he could touch an existence similar to glass, blocking him from the fire.

The inspection was fruitless, Xia Mingdao gave up this unknown thing, the flame that could burn underwater was certainly interesting, but now he had more important things to do. Wu Jiu Literature

"Arthur's father, the foot of King Uther ......" Xia Mingdao repeated this sentence in his mind, his eyes looked at the statues lined up in front of him, and he was a little stunned for a while, although these statues are all very distinctive and can easily distinguish them, but the problem is that Xia Mingdao doesn't know which of them is Yousher.

There are a lot of statues, although it is okay to find them one by one, but the problem is that Xia Mingdao can see that there seem to be boxes and boxes at the feet of these statues, and there is not only one, so if you check them one by one, if you are unlucky, you may be the last one, and it is very likely that Xia Mingdao will waste all the time he holds his breath here.

With his mind spinning rapidly, Xia Mingdao thought that Arthur was the only British king buried in Avalon, that is to say, Avalon's support for Great Britain and Pendragon should have been terminated after Arthur's death, and the future kings did not continue to be associated with this place, and it was because of this that Avalon became a legendary place tied to Arthur, if this is true, for Avalon, Arthur is the last king to be recognized by them, and the statue of Arthur should be the last.

If the statue of Arthur's father Yusher is so speculated, it should be the one before the statue of Arthur?

Thinking like this, Xia Mingdao did not hesitate, and immediately took action and swam towards the last position of the statue group, and at the end of the statue group, there was a king posture holding a long sword in his left hand, nailed to the ground, and holding a knight's spear in his right hand.

When he opened the first box, Xia Mingdao was stunned, the box was full of various styles of jewelry and coins, crowded into the box, and when he opened the other ones, there were the same things inside, in short, gold, money.

Could it be that the billions of wealth of the Pendragon family were actually placed here? The current Pendragon family didn't know what they were looking for in Avalon, but they certainly wouldn't turn a blind eye to the money.

Just the gold at the foot of a statue is enough to make Xia Mingdao a world-famous rich man, but Xia Mingdao understands that he can't take these things out, it's too heavy, and in the face of so much gold, Xia Mingdao prefers his bank card that can make him not hungry.

Ignoring those boxes, Xia Mingdao opened a small box on the top, and there was a beautifully decorated key in the box, but the decoration on it could be seen that it was something meaningless, it may have been deliberately installed for the sake of beauty after the key was created, like a doll that was covered with layers of dresses.

But this key should be the one that Bai Gu said.

Taking out the key, Xia Mingdao was about to swim up when he suddenly saw a long sword on the chest of the last suspected statue of Arthur, which shimmered with the same cold light under the icy fire around him.

Arthur's sword? Xia Mingdao was stunned for a moment, thinking that he was at the bottom of this lake now, could it be that it was the legendary Arthur's Broken Steel Holy Sword, the Sword in the Lake?

Thinking of this, Xia Mingdao hesitated for a moment, then turned his head and swam towards the long sword, stopping at the chest position of the statue of Arthur, the cold long sword was like a necklace hanging on Arthur's chest, right in the position of his heart, which seemed to confirm how unstoppable this sword was during Arthur's lifetime, accompanied by the most legendary king in the history of Great Britain in the north and south, and finally became a myth.

Stretching out his hand, Xia Mingdao hesitated, stared at the long sword in front of him, and slowly approached his hand.

"Buzz!" Suddenly, a circle of ripples rippled from the sword's body, and the violent vibration resounded throughout the underwater space, Xia Mingdao felt as if his body had been hit by a heavy hammer, and fell suddenly, his body knocked over the boxes at the foot of the statue of Arthur, and a large number of coins and jewels buried Xia Mingdao's body.

Struggling, Xia Mingdao got up from the pile of money, accidentally drank two sips of water in a panic, and hurriedly held his breath again after waking up.

Good guy, what is this, is it actually self-defensive?

However, with such a strong movement, Xia Mingdao did not dare to continue to stay here, and when he was about to leave, he suddenly felt a box under his feet blocking him, and looked down, among the boxes that had just fallen from Arthur, one of the boxes was knocked over and opened, and inside was a long sword that was broken in half.

Without thinking about it, Xia Mingdao picked up the box containing the long sword, resealed it, and quickly swam out of the cave.
