According to Dong Tu Nan's instructions, the Gold Devouring Rat King first led him to find Wu Han and the three of them, and then gathered all the rat groups and waited for Dong Tu Nan's order.

"Xiao Jin and me, the rest of the gold devouring rats will sneak into the northern area first, and be on standby!"

As soon as the words fell, in the darkness, countless red points of light began to gather, pouring out of the palace one after another, spreading in all directions with the momentum of the tide.

"Let's go, go to the northern region!"

Dong Tu Nan stood in front of the rat group, beckoned to everyone, and then said to the Golden Rat King without looking back.

The third palace of Yunze, covering an area of about the size of a thousand snow cities, is divided into four areas, southeast, northwest and northwest, each of which is connected by an exclusive stone gate.

Like the Golden Stone Gate that they arrived at earlier, it belongs to the West Gate, which leads to the western region, which is where they are at this time.

These four parts occupy the four corners, and although they are all located in the same underground palace, they are not connected to each other. Only from the corresponding stone gate can you enter the corresponding area.

From the western area where they were located in the east and south to the north gate of the third underground palace, the distance between them was about dozens of miles, and with the cultivation speed of their source martial artists, this distance was only a matter of a moment.

There were almost no obstacles along the way, and soon, Dong Tu Nan and his party came to a place not far from the north gate under the leadership of the Golden Rat King.

The third underground palace, in front of the north gate.

"Xiao Jin, is that the stone gate leading to the northern region?" Looking at a gate as white as snow not far in front of him, Dong Tu Nan asked with some surprise.

He had seen a lot of doors of various styles, but it was the first time he had seen something as strange as what he was looking at. This is completely different from the previous golden stone gate in the west, and the style is also very different.

"That's right, the northern region was the main storage area back then, so it's pretty well guarded. Moreover, what the palace master saw was not a stone door, that door was made by the old palace master with extraterrestrial meteorites mixed with Xuanjing iron. It's as strong as a Heavenly King's hard blow!" replied the Gold Devouring Rat King.

"The strong man of the Heavenly Source Realm struck a blow!" Dong Tu Nan sighed.

The source of heaven is king, and the source of earth is called the teacher.

Just as a strong person in the Earth Source Realm can be called an Earth Master, every Heavenly Source Realm Source Martial Artist is an existence that can be crowned a king, and it is an absolute pillar force in the empire.

When the strength of cultivation has reached their point, they are already close to reaching the sky, and they can easily destroy a mountain range, level a body of water, and go to the heavens and the earth.

This seemingly ordinary gate is actually made of such precious materials. Extraterrestrial meteorites and Xuanjing iron, both of which are rare treasures, are widely used in the casting of various treasures, which can greatly improve the strength of treasures.

"Such a big piece? That old palace master must not be a simple person. Dong Tu Nan thought to himself.

The Golden Rat King seemed to have guessed his thoughts, and when he was thinking about it, he explained: "The old palace master is the palace master of the third palace of Yunze, and he is known as the third palace master of Yunze. At his peak, his cultivation reached the peak of the Tianyuan Realm, and in those days, he was a well-known figure in the Northern Han Empire!"

Speaking of which, the golden retriever looked very proud.

The limbs clinging to Dong Tunan's shoulders, the forelimbs have been raised, and a row of sharp teeth are also grinning, with its fleshy cheeks, it looks like an inexplicable sense of joy.

"Wow, what a cute little mouse!" At this time, Wu Han also came over, and his eyes were suddenly attracted by this golden retriever gold eater.

Seeing that Wu Han, who was about to reach out and touch him, the gold-devouring rat king was actually still strong, and his eyes were shining, and he wanted to go up.

Dong Tu Nan couldn't see its careful thoughts, so he immediately grabbed its little ear, pulled it directly in front of him with his hand, and stared at it with interest.

As the saying goes, a timid rat is like a mouse.

The same is true of the dignified gold devouring rat, Xiao Jin was caught so violently, he immediately panicked, and reacted instinctively, his short limbs began to stroke wildly, and his sharp claws tore through the air flow, producing a friction sound.

"Your Excellency the Palace Master, the old Palace Master specially instructed me to cover you well, you can't mess around, hurry up and put Xiao Jin down!" Xiao Jin said angrily.

It's okay to take out these words to deceive others, but when you say it to Dong Tunan, it seems to have hit a thorn. He has lived two lives, and he has had both god and human experiences, and this little trick is tantamount to a child lying in his opinion, full of loopholes.

Even if the third house lord of Yunze had ordered it, it would not be possible to let it cover itself, at most it would be ordered to use it as an auxiliary for itself. After all, for a strong man like him, it is too simple to find an heir, and since he wants to inherit, he must find the best.

In this way, the new palace master must have a heroic and fearless attitude, perseverance, not relying on anything "covered", but relying on his own footsteps to go down little by little.

"You said that the third palace master of Yunze is a powerhouse of the Heavenly Source Realm, why did he build the underground palace in this Xuanyun small world? and it is such a strange place?" Dong Tu Nan asked deliberately in a suppressed voice.

"How do I know this? Anyway, when I was born, I was already placed in this underground palace by the old palace master. Xiao Jin was stunned and replied.

"Come on," Dong Tu Nan glanced at it a little speechlessly, then threw it back on his shoulder, and then asked, "Let's talk about the specific situation in this northern area, we are going to get ready to go in." ”

By this time they had already reached the north gate, and the group was about to enter.

Xiao Jin didn't hesitate either, and responded normally: "The northern area of the Third Dungeon is actually a small nine-story pavilion. There will be a gatekeeper on each floor inside, and each time you defeat one, you can get the corresponding level of treasures. ”

"Nine-story pavilion, that means you can get nine kinds of treasures?" Dong Tu Nan was a little surprised.

"Theoretically, that's true. Xiao Jin said.

"Isn't that theoretical?" he asked rhetorically.

"That's true, but you have to have the strength to defeat the gatekeepers! Kim explained disdainfully.

Dong Tu Nan couldn't help but feel ashamed, as soon as he heard about the treasure just now, even his thoughts became disordered, and it was really embarrassing to ask such a low-level question.

"What is the strength of the gatekeepers?" he wanted to know what level of cultivation he could generally deal with the first few levels of gatekeepers.

"This... How to put it, no matter how strong you are, the gatekeepers of each level will maintain the same level of cultivation as you. In short, the gatekeeper is a kind of virtual shadow, which may be a human or a source beast, in short, it is to maintain the level of combat with your fellow practitioners, and compare their respective talents and actual combat abilities. Jin took the trouble to explain.

"Then can they also fight beyond the ranks?" this is what Dong Tu Nan cares about.

"Gatekeepers change depending on the challenger, but the most basic criterion is based on your talent or potential. ”

"Generally speaking, if the gatekeeper is a human, it will not be much stronger, and there are not many cases of overstepping, but there is a probability. ”

"But if the gatekeeper is a source beast, then it definitely has the strength to leapfrog the ranks, and it is not ordinarily strong. ”

Dong Tu Nan listened thoughtfully, and finally concluded: "That is to say, the stronger the talent or potential of the challenger, the stronger the strength of the defender in theory, right?"

"That's pretty much it. Xiao Jin nodded slightly.

At this time, Wu Qi also hurriedly stepped forward, glanced at the heavy special gate, and said, "Is this the north gate of the underground palace?

"I think this is much more magnificent than the golden stone door just now! There is even an unusual atmosphere. Han Wancheng groped his cheek stubble with his rough palms and started talking to Wu Qi.

As for Wu Han on the side, after approaching this door, he remained silent. I saw her frowning, with a touch of melancholy between her soft eyebrows, and her expression looked very unnatural.

Dong Tu Nan also found out for the first time, and asked with concern in confusion: "Did something happen?"

She shook her head slightly, her brow furrowed at all, and her tone contained concern: "I seem to faintly hear the sound of a fight inside. ”

Regarding the cultivation strength of the Martial Han Gathering Source Realm, Dong Tu Nan has always been convinced. At this moment, since she heard an unusual sound, it must not be made up out of thin air.

"You say, could it be the mountain wolf and the rest of the celestials?" she stared ahead with a look of mixed expression.

Wu Han was obviously worried that the battle of the heavens would affect his own people.

After all, when it comes to grouping, my own group is the most declining, and in terms of the overall level, compared with other groups, there is no advantage at all.

The other groups are not all Tianjiao, at least there are a bunch of elites, and their team leaders are basically characters at the second level of Tianjiao.

As the only source martial artist of the Gathering Source Realm here, Wu Han's strength is not very strong, and he can only barely rank at the third level of Tianjiao.

Therefore, there are many groups that are eyeing their own group, once it is time to fight, pinch persimmons to pick the soft pinch, and deal with people to pick the weak.

In this way, at that time, my side will fall into a dead end.

Dong Tu Nan listened to her words, and naturally could understand what she was worried about.

However, this is unavoidable, no matter what, we still have to meet in the end, and our own group is bound to have a fierce battle with other groups, but I don't know which group it will be with.

Therefore, the most important thing now is to improve their respective strengths as soon as possible, so that they can have a few chances of winning in the final battle!

In addition, the reason why Dong Tu Nan is so calm is that he has become the new owner of this third underground palace. He was able to know many hidden things in advance, which also added a guarantee for the group to find opportunities.

Thinking of this, Dong Tu Nan just smiled faintly and comforted: "What should be faced, or faced, what's the use of escaping? Let's go! Take this opportunity to meet those so-called Tianjiao!"

After all, inside the huge refined gate, there is a chic back when you walk in.
