For a long time, Fang Han still hadn't found the sea snake, and just when he was about to give up, he suddenly saw a section of stone that looked like a city wall appear not far away.

"How can there be a city wall at such a deep seabed?" Fang Han wondered, his current location was about more than three hundred meters below the sea level, which was similar to the diving record of humans with the help of diving equipment.

In other words, there is no way for humans to survive at the bottom of the sea, how can it be possible to build walls at such a deep seabed?

Curious, he swam over and found that it was indeed a city wall. However, the wall was not made of stone, but of adobe, a cuboid made of clay and forage. This kind of adobe was used by northerners to build houses, although it is not known that the adobe on these walls is different from the adobe used to build houses, but the effect should be the same.

But this kind of adobe can't stop the erosion of the sea, and it's not as good as stone!

Thinking of this, Fang Han poked it with his finger, but his finger poked it directly, leaving a round hole on it.

Well, it did resist the erosion of the sea, but because the sea was dense and it was not affected by the impact of fish and shrimp, it would still maintain this shape.

If there is a city wall, then it means that there is a city, which is the consensus of the archaeological community. Although Fang Han was not in the archaeological world, he had explored a lot of ruins, and he immediately thought that behind this wall, there might be an ancient city.

The city wall was not high, Fang Han gently went up more than a meter, his eyes crossed the city wall, and he saw the things inside.

I saw that there were many houses made of adobe inside, but these houses were not as lucky as the city walls, and they had all collapsed. Think about it, too, how can such an unsturdy house still be intact in the sea? After their walls are softened by the seawater, they cannot bear their covers at all, and when their covers are softened, they will definitely collapse first.

Fang Han squinted his eyes slightly, the scale of this city seemed to be quite large! he couldn't see the end at a glance, this was not like the ancient cities that were found on land.

He was interested, although he did not find the shore of the Bohai Sea this time, but he found an ancient city, which was also rewarding. This ancient city is in the sea of more than 300 meters, then its age must be very old, if you can find something to prove the identity of this ancient city, then it is enough to shake the archaeological and historical world.

Of course, for this kind of mundane thing, Fang Han was actually not interested. What he was really interested in was how far back this city was, and if it was a city from 10,000 years ago, would it also be a ruin? The ruins represented magic weapons and ancient spells, which couldn't help but be unmoved.

Thinking that there might be a magic weapon, Fang Han immediately rushed into the city with a flying sword. The result should be that the speed of the rush is too fast, and the fluctuations caused by it will knock down the intact wall just over there.

"Bang!"

There was a soft sound, and the mud flowers flew. If these archaeologists saw this, they would definitely point at Fang Han's nose and scold their mother.

However, Fang Han didn't care at all, not to mention that this kind of city wall could no longer be protected, even if it could be protected, it was completely unnecessary, those mundane concepts could no longer influence him.

Fang Han quickly shuttled around the city, and the fluctuations brought along the way stirred up those damaged houses. But after searching for more than half an hour, he still didn't find half of what looked like a magic weapon in the city.

"Huh?" he found a wooden sign, which was a very ordinary wooden sign, but with words on it.

"Is this an oracle bone inscription?" Fang Han looked at the somewhat vague symbol on it, it was not so much a word as a painting.

There is still a lot of water next to a city tower, could it be a map? Fang Han was a little puzzled.

"Wait!" his eyes widened suddenly, the water's edge is also called the water's edge, the water's edge city, is this the shore of the Bohai Sea?

Fang Han's eyes widened and he looked around, how could there be any appearance of the Dragon Palace here?

No way, this is definitely not the shore of the Bohai Sea, maybe it is another coast, or this plank is a map that can guide you to the shore of the Bohai Sea.

So, he rubbed his hand on the board, trying to wipe off the moss that covered it.

"Click!"

As a result, the planks were directly crushed into slag.

"Damn!" Fang Han couldn't help but burst into a foul mouth, was this teasing himself?

"Wow!" A splash came from a distance, Fang Han turned around abruptly, followed the sound, and then saw the huge sea snake rushing towards him.

It had a fierce light in its eyes, as fast as an arrow, and rushed to Fang Han's approach, slamming its mouth open, revealing two pairs of huge fangs, and biting it towards Fang Han.

Fang Han was in annoyance, and when he saw the sea snake rushing towards him, he immediately couldn't help but be angry, "Since you want to die, I will fulfill you!"

As Fang Han spoke, he took out the green jade sword, quickly injected mana into it, turned the green jade sword into a giant sword, and shot at the sea snake.

The sea snake saw the green jade giant sword, a trace of shock flashed in his eyes, then he closed his mouth suddenly, and then his head sank, and he dodged the attack of the green jade giant sword, and continued to rush towards Fang Han with the green jade giant sword.

"Boom!"

Fang Han drove the purple gold sword to avoid the sea snake's bite, and then with a little foot, the purple gold sword shot at the sea snake's body.

"Dang!" A sound of gold and iron clashing sounded, and the purple gold sword was bounced up. Fang Han immediately realized that this guy's defensive ability was very strong.

The sea snake had already turned its head and rushed towards Fang Han again, Fang Han hurriedly pulled the purple gold sword back, stepped on it under his feet and led him to distance himself from the sea snake.

Since you can't start from the scales, it's better to start with the mouth. With his hand stretched out, the green jade giant sword also turned a corner in the sea water from behind, and then shot at the sea snake.

The sea snake saw that Fang Han was still attacking like just now, and his eyes couldn't help but show a trace of contempt. There was no way to take Fang Han's attack like this just now, and now he still uses this kind of attack, he simply doesn't take it seriously!

Thinking of this, his head sank again, and he wanted to repeat his old tricks, rushing from under the green jade giant sword.

"Innocent!" Fang Leng laughed, and with a twist of the sword technique in his hand, the green jade giant sword immediately stood up.

The width of the green jade giant sword was five or six meters, and the distance was very close before it changed, so it was too late for the sea snake to dodge. It looked at the jade giant sword that was getting closer and closer in horror, a look of shame appeared in its eyes, and then a mana shield appeared on its body, wrapping its head.

"Dang!"

The green jade giant sword hit the mana shield, and it didn't break it, but the green jade giant sword was knocked out and flew out.

"What's the situation?" Fang Han frowned, why was this sea snake so strong? Could it be that he was a Flying Ascension Monster? That's why he could resist the attack of the Azure Jade Giant Sword? But he didn't feel the power of the Ascension Stage on its body at all!

The sea snake saw that he had knocked the green jade giant sword away, and his eyes immediately showed a fierce look. Originally, it thought that the giant sword was very powerful!, but now that it looked at it, it was nothing more than that, smiled at Fang Han, and continued to rush over.
