There is no trace of lifeform in the Dragon Palace, which is only one of the suspicions.

In addition, the entire interior of the Dragon Palace gave Tang Chen the feeling that it was not like a palace at all, but more like an independent space like a secret realm, here, there was actually a sky! If it was really just a palace, it would be too incredible!

With doubts, Tang Chen withdrew his soul sense from the Dragon Palace.

"At first glance, there is no danger in it, but it doesn't seem to be of much value to such a Dragon Palace, why would it be unreasonable to set up an isolation array here, and send so many mid-level Star Saint powerhouses to guard it......"

Tang Chen thought a little unwillingly, and after some thought, he finally decided to sneak in and investigate, after all, in many cases, the role of soul consciousness is very limited.

For example, if there was a high-level saint-grade psychedelic array in the Dragon Palace, with Tang Chen's current soul power cultivation, it would be difficult not to be confused just by relying on soul power exploration, and he had to personally investigate on the spot before it was possible to solve it with the formation path cultivation.

This isolation array under the water was only a mid-level saint grade, it was not too difficult for Tang Chen to crack it, it only took him ten minutes to open a small door two meters square on the barrier of this array, and it had not yet triggered its early warning mechanism, so those Star Saint powerhouses stationed outside did not notice the abnormality.

Tang Chen got through the doorway on the barrier and swam straight towards the Dragon Palace, protected by the Guardian Xinggang, and the lake water did not soak his clothes.

Although he had used his soul sense to investigate before, he didn't dare to be careless, so he didn't swim fast, and while swimming, he paid attention to all the movements around him.

From the edge of the lake to the middle of the lake, the distance was about fifty miles or so, and with Tang Chen's speed, as long as he wanted to, he could reach it with a dodge, but it took him a full ten minutes.

If it were usual, he would have been able to fly thousands of miles in ten minutes.

The reason for this caution is mainly due to the fact that the legend has it that this dragon palace is something from ancient times, and in the eyes of people, ancient times are usually synonymous with unfathomable, fascinating and taboo.

When he arrives at the Dragon Palace at the bottom of the lake, he finally finds something suspicious.

"Sure enough, there is a problem......

Tang Chen muttered in his heart, he stood outside the Dragon Palace, and did not rush in, but radiated out his soul sense and carefully investigated it again.

Soul consciousness is similar to the eye's vision, which decays with increasing distance, so it has a limit.

Conversely, the closer the distance, the better the detection effect of the soul sense.

At this time, Tang Chen's soul sense did not enter it through the gate of the Dragon Palace, but he found that his soul sense actually penetrated the four walls of the Dragon Palace and entered the interior of the Dragon Palace, which was very abnormal!

Normally, a person's soul consciousness is not penetrating, and it is impossible to penetrate an object and get a glimpse of its internal situation.

The reason why the soul consciousness can penetrate into the interior of many spaces, such as houses, cabinets, etc., is because these spaces are not absolutely sealed, and there are many gaps.

If it is an absolutely confined space, such as the star soul space of the star person, the room with an isolation array, etc., it is impossible for the soul sense to easily penetrate it.

However, Tang Chen's soul sense actually penetrated the four walls of the Dragon Palace!

"Could it be that this Dragon Palace is not a real thing, but just an illusion generated by the star array?"

Tang Chen secretly guessed that he felt that this possibility was very high, because he knew the particularity of his soul consciousness, and he had a strong snooping ability into the soul power and star power of others, so that he could detect the sound transmission of other people's soul consciousness, and he could also penetrate the star array enchantment laid by others, but it was absolutely impossible to penetrate the actual object, unless the object was penetrated with the destructive power of soul power.

He crouched down, reached out and grabbed a handful of the sand at the bottom of the lake, then let go of it, letting it spill from his fingers, it was all very real.

However, Tang Chen became more and more sure that all this was fake, even the bottom of the lake was fake, these seemingly real fine sands, when deposited at the bottom of the lake, were indeed like real objects, blocking his soul consciousness, but when they were grabbed and sprinkled in the lake water, he found that his soul consciousness could penetrate every fine sand, as if there was nothing.

"It seems that a high-grade psychedelic array has been set up at the bottom of the entire lake, and if it weren't for my special soul power, I wouldn't be able to see it at all...... Everyone else is likely to have been deceived by this fake Dragon Palace......"

Tang Chen thought firmly, and at the same time became more curious about the bottom of this lake, being able to lay out such a high-grade psychedelic array here, it can be seen that there must be a more precious secret hidden in it, maybe there are any treasures, otherwise, who would be idle and spend such a big price to lay such a star array here?

Knowing this, he began to carpet search the bottom of the lake.

However, he searched carefully for more than an hour, probing the entire bottom of the lake, but found no sign of the existence of the Array Gate.

Generally speaking, without a formation gate, you can't enter the formation, unless you break the barrier of the star array with strength.

However, the psychedelic array is different from the ordinary star array, its enchantment is very hidden, and it is often hidden in the depths of the illusion, which is difficult to detect.

Therefore, there are only two commonly used methods to break the psychedelic array, the first is to find its formation gate, and the other is to break the formation with the array, and use the superior array power to interfere with the psychedelic array, so as to make it invalid.

Tang Chen's formation cultivation was sufficient, but he couldn't set up a high-level holy array now, and if he wanted to break the formation with an array, it was impossible right now.

The only way is to find the gate of this formation.

Tang Chen stood in front of the Dragon Palace, looked at the Dragon Palace, and then looked at the bottom of the lake, and decided to try to see if he could directly "dig" through the bottom of the lake and enter the interior of this array.

It's a brutal solution, but it's also a method that you have to try when looking for a formation.

Most of the time, this method will not be successful, but it can summarize some useful reference information for finding the formation gate.

Tang Chen came to a place that was suspected to be a formation gate, and immediately took out the Nine Tribulation Sword, used the sword instead of drilling, and the body and the sword merged, and the whole person turned into a sharp whirlwind, drilling towards the bottom of the lake.

A strong undercurrent vortex was suddenly generated at the bottom of the lake, and the water in the lake within a radius of several miles was surging, but fortunately, there was an isolation array above, which did not affect the water layer close to the lake, otherwise, such a big movement would definitely attract the attention of the Star Saint powerhouses stationed on the lakeside.

Tang Chen drilled at such a high speed for half an hour, and the whole person had already submerged in the depths of the fine sand at the bottom of the lake, but he still failed to penetrate the bottom of the lake.

"It doesn't seem to be here......"
