This boundless city is very noisy, and the streets and alleys are discussing what secret realm, and the discussion is continuous. This is a lot of Spirit Emperors and Spirit Sect cultivators appearing on the streets where there is an endless stream of people.

The discussion of everyone on the street also gave Zhao Chen a lot of information. Zhao Chen drifted through the crowd for a while, and then walked to a restaurant!

This is not an ordinary restaurant, the people who enter this restaurant are all cultivators, and the restaurant is naturally a spiritual vegetable, composed of the meat of demonic beasts and various spiritual materials. The use of spiritual vegetables is also of some effect to cultivators.

Zhao Chen came to a window position and sat down, and then a shopkeeper ran to Zhao Chen's side and asked with a smile: "This boy, what do you want? Our small shop has just captured a big fish at the level of a spirit king, and with more than a dozen kinds of elixirs as auxiliary materials, the effect is comparable to that of a five-grade elixir! Now only 500,000 high-grade spirit stones are needed!"

Zhao Chen couldn't help but smile, the second child in this store is really good at selling, and it is 500,000 high-grade spirit stones as soon as it comes up, but Zhao Chen also feels that it doesn't matter, so he said softly: "Just have a big fish you said!"

"Okay, Childe, please wait!" said the shopkeeper excitedly. He didn't expect that Zhao Chen would really order, but the shopkeeper was also very happy, after all, he could get more spirit stones when the time came.

After a while, a piece of color and fragrance was complete, sprinkled with elixir treasures, and placed on Zhao Chen's table, and Zhao Chen was given a pot of spirit wine.

At this moment, a middle-aged man opposite Zhao Chen came to the opposite side of Zhao Chen uninvited, and said with a smile: "Little brother, is it the first time to come to this Boundless City?"

"Yes, it's the first time I'm here!" Zhao Chen also nodded and said.

"Is that little brother willing to go to the secret realm under the sea?" The middle-aged man couldn't help but lower his voice: "Dissatisfied little brother, I have been gathering people recently, in order to explore the secret realm under the sea!"

Zhao Chen couldn't help but smile and said: "Since there is such a good thing, you are a strong Spirit Emperor, it is easy to find someone, I believe many people are very happy!"

The information of this middle-aged man soon appeared in Zhao Chen's eyes, this time Zhao Chen was a little shocked, the man looked ordinary, but he didn't expect it to be the strength of the Spirit Emperor.

"I can't see through you, little brother, and the little brother is so young, he has 500,000 high-grade spirit stones at hand, I believe that the little brother is definitely not simple!" the middle-aged man smiled.

The middle-aged man saw that Zhao Chen didn't speak, and then continued: "If the little brother agrees, we will go to sea in a few days, and we will explore the secret realm together.

Zhao Chen also asked slightly at this time, "Do you know where the Heavenly Machine Sect is?"

"Little brother, aren't you joking, the Heavenly Machine Sect has been hiding from the world for a long time, and the world can't find out the existence of the Heavenly Machine Sect at all, but there is a rumor that the Heavenly Machine Sect is somewhere in the endless sea, and every year there are many people looking for this Heavenly Machine Sect, but in the end they all end up failing!

"Yes, I came to this Boundless City for the Heavenly Machine Sect, I can promise you to explore the secret realm, and I don't want the things inside, but after the secret realm is explored, this ship will be used for me, how about it?" Zhao Chen nodded.

"Of course this is okay, after we explore the secret realm, we will stay at sea for a month, and during this time, we can also help the little brother find this Heavenly Machine Sect! But little brother, this Heavenly Machine Sect has disappeared for a long time after all, so we must return after a month!" the middle-aged man said quickly.

"I naturally know this, when to leave?" Zhao Chen said.

"Meet at the dock at sunrise tomorrow!" reminded the middle-aged man.

"Okay, I'll be there on time!" Zhao Chen finished speaking at this time, and then concentrated on eating.

......

After resting for one night, Zhao Chen came to the agreed place on time, Boundless Port.

Zhao Chen also looked at the middle-aged man at this time, and there were more than a dozen figures around him, all of which were the strength of the Spirit King.

"Little brother, it's just right that you've arrived, we'll set off right away!" The middle-aged man looked at Zhao Chen's arrival and immediately greeted him.

Soon the middle-aged man introduced each other, and Zhao Chen and them also had a simple understanding.

Then he boarded the ship, this ship is a medium-sized ship, although many of them are very large, but it is enough for Zhao Chen and a dozen of them, there are many rooms on the ship, basically one person per room.

The ship in this world does not rely on manpower, but a kind of formation, as long as the spirit stone is constantly invested, the ship will continue to advance! It can be said that it is very advanced, but the consumption of spirit stones is also huge, but the efficiency is also quite high.

Zhao Chen also began to rest in the room, and a few hours later, Zhao Chen heard the voice of a middle-aged man.

"Everyone, it's time to get there!"

Dozens of figures came to the board of the ship in an instant, looking at the vast sea, there was not a single island.

"The entrance to the secret realm is just below us, you will be tighter with me in a while, don't fall behind!" the middle-aged man said slowly. Seeing that everyone nodded, the middle-aged man also jumped directly into the sea, and the others also jumped into the sea one after another.

Diving into a depth of about a few thousand meters, Zhao Chen followed the middle-aged man behind him and saw a gate!

The gate looked very dilapidated and full of cracks.

This mysterious symbol is also engraved on this stone gate, and the peculiar pattern seems to tell this distant and mysterious history!

I saw that the middle-aged man touched the stone gate with his hand, and it turned into a ray of light and poured into it, Zhao Chen also touched the stone gate in the way of the middle-aged man, and Zhao Chen instantly felt a strong suction force and sucked himself in.

The next moment, Zhao Chen opened his eyes and found that he was already on the boundless earth, where he could see broken and fragmented buildings everywhere.

Soon, dozens of people entered the secret realm smoothly, and after the middle-aged man confirmed the direction, he led everyone to rush in one direction.

However, this road is not very peaceful, and there are many powerful demonic beasts in this secret realm, and one of them did not pay attention, so he was directly swallowed by the sudden attack of the demonic beast.

Fortunately, the middle-aged man reacted quickly and directly punched out and killed the monster, otherwise someone would be buried in the belly of the monster.

Next, the middle-aged man also slowed down, and at the same time they were more cautious, after all, one less person, the overall strength would drop a lot!

At this time, the middle-aged man also arranged for Zhao Chen to walk at the end, although he didn't know Zhao Chen's specific strength, he only felt that he told him that Zhao Chen's strength might be on par with him.

Zhao Chen didn't refuse, but came directly to the back of the team!
