Tang Chen's soul sense radiated out, except for those who stayed in the house and had the protection of the isolation array, the state of everyone else in the range was clearly grasped by him, and he himself used the isolation soul technique, and no one could detect him with his soul sense.

Moreover, his speed is extremely fast, and with the naked eye, he can't even touch his shadow at all.

In this way, in just a few breaths, he touched the edge of the Hidden Dragon Lake and hid under a big tree by the lake.

The reason why he didn't dive into the lake immediately was because around the lake, there were some Star Saint powerhouses stationed everywhere, and the soul consciousness of these people was completely monitoring the entire lake all the time, and no wind or grass could escape their detection.

"How do you avoid their surveillance?"

Tang Chen frowned and thought, and quickly came up with a solution, in his opinion, this should be the easiest and most effective way to deal with the situation in front of him.

Under the tree, he refined some psychedelic arrays in a short period of time, and then came to the lake, threw these arrays one after another, and instantly laid down a small psychedelic array covering a radius of about two meters.

It's just that when this array was laid down, it still attracted the attention of those Star Saint powerhouses in the dark.

Soon, a fifth-order Star Saint rushed over and took a closer look at the lake, but found nothing, and finally had to return to his post on duty with doubts in his head.

After this fifth-order star saint left, Tang Chen came out from behind the big tree not far away and rushed into the psychedelic array at an extremely fast speed.

The psychedelic array simulates its surroundings so that it is impossible to discern the changes in them, and even if they are huge waves inside, they are still as calm as the surface of the nearby lake.

Moreover, this array is not only effective on the surface of the lake, but extends to about ten meters below the surface of the lake, and the waters within this range are under the effect of this array.

After Tang Chen got into the lake, he immediately dived down.

At this time, even if there was no psychedelic array, he was not worried about being discovered, because he had cast a soul sense isolation technique on his body, and others would not be able to find him at all, at most they would only think that he was just an undercurrent at the bottom of the lake.

When he dived about ten meters underwater, Tang Chen discovered an enchantment of the Isolation Array.

The grade of this array is not low, it has even reached the intermediate level of saint grade, but with Tang Chen's soul power cultivation, it is not very difficult to penetrate the soul sense.

Even if he didn't use soul sense penetration, with the cultivation of the formation path, he would be able to easily break through this formation.

For the sake of insurance, Tang Chen did not choose to break the formation at the first time, but infiltrated inward with his soul sense, wanting to see what was inside before making the next step.

After about five minutes, his soul consciousness finally broke through the barrier of the isolation array and entered it as if he had passed through a labyrinth.

However, below the barrier, Tang Chen didn't see anything other than the deeper lake, not even a fish, which was a bit strange......

Tang Chen was slightly surprised, and while secretly speculating about why the person who set up the formation had set up the isolation array in such a shallow place from the water surface, he radiated his soul sense to the depths of the lake.

After about fifty meters deeper, Tang Chen saw the bottom of the lake, where fine sand was spread on the bottom of the lake, and some rocks of different sizes and shapes were dotted in a disorderly manner.

Both the sand and the rocks are very clean, without a trace of silt, as pure as if embedded in amber.

In the center of the bottom of the lake, there are more than a dozen huge stone pillars of unknown material towering, and behind the stone pillars is a stone palace in a square circle, the appearance of the palace looks very simple, without any trace of luxury.

Above the half-open and half-closed huge stone door, there were two ancient characters carved on, and Tang Chen recognized them at a glance, which was the word "Dragon Palace".

"There really is a dragon palace!"

Tang Chen was secretly surprised, he didn't expect that the legend would be true.

At the same time, he also probably understood the purpose of the isolation array on the lake, probably to prevent others from prying eyes.

However, an Isolation Array of the Intermediate Rank Saint Rank can only prevent people below the Intermediate Star Saint, and it is not of much use to the powerhouses above the Intermediate Star Saint, in this case, wouldn't it be a superfluous move to set up this Isolation Array?

What Tang Chen didn't know was that in the entire Holy Heaven, the Holy Array Masters were very rare, and in the Hidden Dragon Star Domain, the most powerful Saint Array Masters had only reached the mid-level Holy Array, and there were no high-level Saint Array Masters at all, so they could only lay out the mid-level Saint Rank Star Array, which was really a helpless move.

And those Star Saint powerhouses who can really prevent others from coveting them are those Star Saint powerhouses stationed on the shore of Hidden Dragon Lake, as long as they don't encounter high-level Star Saints, there won't be much of a problem.

Tang Chen's soul sense passed through the gate of the Dragon Palace and entered the Dragon Palace.

Inside, there is a cave, like a star weapon with spatial attributes, it is far from being the size of a square circle as seen outside.

Tang Chen roughly estimated that there was at least a thousand miles in the Dragon Palace.

In this regard, Tang Chen was not surprised, the place where the ancient dragon god lived in the legend, if it was only a large number of miles in the radius, it would be really strange.

It's just that although the Dragon Palace is large, it hasn't seen any living beings, and it is even more unknown whether the legendary ancient dragon god really lives here.

Tang Chen hesitated for a moment, and soon decided to go deep into the Dragon Palace to explore, this was not dangerous or difficult for him, after all, what he entered here now was just a soul sense, even if he encountered danger, at most he would only lose a trace of soul power.

Behind the gate of the Dragon Palace, it is not a similar palace, but a world, with strange and beautiful coral stones, piled up everywhere like hills, embellishing the Dragon Palace that originally looked unpretentious and unpretentious.

Moreover, each group of coral stones is like a wall, separating the Dragon Palace into a sense of layering, obviously only a thousand miles in radius, but it seems to be thousands of miles, tens of thousands of miles.

Tang Chen controlled his soul sense to quickly radiate towards the depths of the Dragon Palace, and soon swept the entire Dragon Palace.

However, he didn't see the so-called ancient dragon god at all, not even a single water creature.

"It's really strange, it's only so big here, if there really is a dragon god, it should be easy to spot. What's more, as a dragon god, can't there be a group of subordinates to serve?......"

Tang Chen thought wildly, in fact, he also knew that if this Dragon Palace was really something from ancient times, it would have been tens of thousands of years, even if there were creatures that existed, they had long been wiped out by the long river of time, how could he see it?
