As I said before, there have been three civilizations in this world, and there were originally many landmasses, which for some reason were submerged under the sea. Then the city under the sea is left by the predecessors.

However, this kind of city is very difficult to encounter, and you are extremely lucky to meet it, if it is not a coincidence, plus you have prepared yourself, you will not be able to come out alive, so you are really a lucky guy. The captain quipped.

By the way, you said you picked up a clear box, take it out and I'll take a look. The captain said.

Cui Chop fingers moved, and a transparent box appeared on the driftwood.

Well, I've seen this material before, it's an extremely rare ore refined, but it's all forged by predecessors, and no one can refine this anymore.

I remember that the last time we salvaged a knife smaller than this, it was really a magic weapon that cut iron like mud and broke hair. It's just that it was stolen in the later period, and this material has never been seen again.

Well,There's something in there.,This material should be well preserved.,But it seems to have some kind of password or something.,I can't open it.。 Keep it for now, maybe you have a chance to open it later. The captain said.

Let's go, then, the captain said.

Cui Chu put away the transparent box, took the captain's hand, and various scenery flashed in front of him.

About half an hour later, the two of them had appeared on the docks of the Bota Empire. Cui then returned home, and the captain teleported away.

Early the next morning, Titan, Susan, and Xiaoyan, who were about to go to the store, saw Cui Zhan who was practicing in the courtyard in the morning and said hello.

Uncle Cui, I've made breakfast, remember to eat hot after a morning exercise, don't eat cold, it's not good for the stomach. Susan said with concern.

Yes, don't carry so many heavy loads home in the future, there is no shortage of those at home, aren't Susan and I also making money. You go out and go on a bird-walk. It's good to sing and sing. Titan said.

Haha, yes. Cui Zhan nodded with satisfaction.

At this time, Yun'er also went out, carrying a schoolbag to school, looking Lori.

Titan Shu Xiao, Sister Susan, Dad, Xiao Yanyan, people are going to school, and people are going to eat braised fish at night!

At this time, Cui Shu, who was in the bedroom on the third floor, saw it clearly, and came back too late last night, so he didn't disturb his family.

Immediately, Cui Shu opened the window, jumped down, and appeared in front of several people with a look of falling from the sky.

Oops! trapeze?, Titan said.

Cui Choi you're back, great, how is it, is it going to go out?, Sophie asked.

Son, it's time to come back, come, go to breakfast with Dad.

Brother, I miss you so much, have you brought good food to others?

Therefore, this person is not as good anywhere as at home, and the calm, comfortable, and peaceful atmosphere can only be found at home.

You said you're the team leader? yes, that's my son. But son, what you don't know is that your father and I are now the captain of the Chengguan Brigade. Cui Zhan said.

Can you stay at home for a while this time?" Cui Zhan asked.

For about ten days, I have to listen to the teacher's instructions. Cui replied.

After breakfast, father and son went to work and the dock. separated.

On the docks, Cui Chu inquired and learned that the ship of the Cultivator Academy had not returned. There are worries in my heart. But I believe that Mr. Xinghuo is here, there should be no problem.

However, this elixir is really a good thing, if you have the opportunity to come across a good medicine recipe, you must buy it. If it weren't for this Water Avoidance Pill and Qi Gathering Pill, as well as the Night Vision Pill, I believe that I would have died a long time ago.

Since the ship hasn't returned, you might as well go to the auction house. Cui Chu thought.

In the auction hall, the popularity is still very high, and Susan is also extremely happy when she sees Cui Shu, after all, the one who can take away 100,000 weapons and come back alive must be a hard-hearted person.

The first lot, the seventh-level beast pill.

The second piece is the ninth-level exercises.

The third piece, three Qi Collecting Pills.

......

Until the end, Cui Chu did not have a favorite lot.

Cui then said goodbye to Sophie and walked towards the Cultivator Market.

In the cultivator market, Cui Shu, who was wandering on the first floor, looked at the real and fake things on the stalls, and he couldn't arouse any interest.

So he walked towards the second floor, but at the moment when Cui Qi's front foot had already climbed the stairs, he squinted and saw that something on a stall on the first floor was particularly familiar next to the stairs. Take a closer look. I can't help but feel shocked!

A broken tip of a knife, to be exact, turned out to be the tip of his own broken blade.

Cui Chu walked into the stall and saw that the stall owner was an old man, staring at the crowd with a pair of eyes that did not match his age under the black robe.

Cui Chu looked at it casually, and also asked a few unrelated items for price or exchange method.

When Choi asked the tip of the knife. The old man's eyes were visibly stunned, and then they returned to flatness.

The little doll is interested in this? This is not an ordinary metal, this metal is a thousand forged steel, have you ever seen a similar blade?" the old man asked kindly.

I've never seen it, but I think this knife tip can be sold for money, so I'm just a little curious. Cui replied.

Oh yes, that's not far away. The old man then said coldly.

I mean, do you sell or trade this knife? I'm kind of interested. Cui Chu said.

In exchange, the second-level beast pill will be sold for 500 million. The old man said lightly.

The boss with Cui beheading his mouth didn't know how to communicate with the old man for a while. This way of bidding is clearly not wanting to sell!

Looking at the tip of the knife in the cupboard with regret, the young man turned around and went upstairs, and at this time, the eyes of the old black man were also staring closely at the young man walking upstairs, and a fierce killing intent burst out from his eyes.

On the fourth floor, Su Lao was there, Cui Chu handed over the medicine list, bought some medicinal materials, and went downstairs after saying goodbye to Su Lao, when he walked to the first floor, Cui Chu found that the old man's stall had been removed, Cui Chu sighed regretfully, and then walked in the direction of home.

At night, Cui Chu was teleported to a cave by the captain and was about to synthesize the elixir, but the captain's face immediately changed, looked at Cui Chu and asked: Apprentice, what happened to you or someone you met today. The captain asked.

No, Cui Chu was puzzled, turned his head and thought, by the way, I met the tip of the remnant blade. So I told you about the cultivator's market.

The captain said with a stern expression after listening. You have an aura similar to my flesh, and you are being followed. Now I'll teleport you outside, you can just sit on the top of the mountain and cultivate, don't move anything, understand?"

Well, I understand, as soon as Cui Qi's words fell, he appeared on a stone platform somewhere on the top of the mountain. As the captain said, sit back and get lucky.

For about half an hour, a gust of wind came from behind Cui Shu, Cui Chu didn't move, and at the same time put away the mental power that was released.

Little doll, tell me why you're interested in the tip of my knife!

An old man's voice came from behind.

What is the tip of the knife? Cui Shu turned his head and looked at the black-robed old man in front of him and asked.

Little doll, you can't hide it from me, the exercises you practice are very similar to a friend of mine, and some time ago I heard that a little doll once used the remnant blade with an iron lock.

Is it you?" the old man asked with slightly squinted eyes, but the murderous aura had already surfaced in front of him.

I don't know what you're talking about, don't delay my practice, okay?" Cui said calmly.

Well, in that case, you should die! The old man changed his words, and at the same time slashed at Cui with a palm. The palm wind is vigorous and powerful, and the cultivation qi is strong and domineering.

At this moment, a tall figure appeared behind Cui Shu, and the two of them used their palms together, and with a click, the old man's hand bones were instantly broken.
