Tang Chen stopped drilling down, he roughly estimated that with his previous speed of drilling, half an hour, to say the least, can drill thousands of miles deep, such a depth can not penetrate the bottom of the lake, indicating that the place must be wrong.

You'll have to try again in a different place.

After that, he changed several places that were suspected of being arrays, and drilled everywhere for half an hour, but they all returned in vain.

At this time, nearly four hours had passed since he entered the bottom of the lake, and he had to hurry, otherwise, after another four or five hours, the sky would gradually get brighter, and there would be many inconveniences in his movements.

He couldn't stay at the bottom of the lake all the time and not go out, because he didn't know if the domain master would send someone to find him again, and those teammates of Mu Long's team would probably continue to come to him for advice.

Tang Chen returned to the gate of the Dragon Palace, hesitated slightly, and then stepped forward and walked in through the half-open palace gate.

When I arrived in the Dragon Palace, what I saw in front of me was exactly the same as what I saw with my soul consciousness before, there was no water in it, but there were colorful coral mountains everywhere, and above my head was a blue sky, without a trace of clouds, as clear as a piece of blue crystal without impurities.

Tang Chen took a slight look at the interior of the Dragon Palace, and then quickly marched in one direction, as he went, he used his soul sense to investigate the places he passed up close.

An hour later, he thoroughly inspected the Dragon Palace with a radius of nearly a thousand miles, and determined that there was no obvious array gate in it, so the formation gate of this psychedelic array must be hidden somewhere, and he needed to speculate with his knowledge and experience of the formation path.

In the process of investigating, he has delineated nine places that are most likely to be the location of the array gates, these places are very consistent with the principle of the formation gate setting in the formation path, and the terrain is also relatively unique, they are the only nine lakes in the Dragon Palace.

There is a dragon palace in the lake, and there is a lake in the dragon palace, which in itself implies something peculiar.

Next, Tang Chen began to go deep into these nine lakes one by one, looking for the location of the formation gate.

However, it took nearly three hours and still found nothing.

Seeing that it was almost dawn, Tang Chen had no choice but to give up the search for the time being, retreat from the Dragon Palace, and return to the shore of the lake.

At this time, although the sky was still dark, there was a faint light in the eastern sky, which was a sign of dawn, and in another hour, the night would be swept away by this light.

Tang Chen took advantage of the night and quietly returned to his residence.

He sat cross-legged on the bed, originally wanting to cultivate on this, but his mind couldn't calm down for a while, and the scene in the Dragon Palace kept replaying in his mind uncontrollably.

Seeing that he couldn't meditate on cultivation, he simply stopped the idea of cultivation and thought about the affairs of the Dragon Palace.

While recalling the various scenes in the Dragon Palace, he verified them one by one with the formation path, and it was not until dawn that he realized something.

"It seems that I have been inadvertently misled by habitual thinking, thinking that it is easier to penetrate the bottom of the lake in low-lying places, but in fact, the bottom of the lake is just an illusion, and it cannot be viewed by the rules of the real world.

Now that I think about it, those Coral Hills are more likely to be the location of the Formation Gate. ”

Tang Chen thought in his heart, and decided to go to the bottom of the lake after nightfall, to verify his speculation, and believed that he should be able to find the formation gate.

......

The matter of the Dragon Palace came to an end for the time being, and Tang Chen could finally calm down and start cultivating.

It's just that when it was dawn, he heard someone knocking on the door, and with his soul sense, he found that it was several teammates of Mu Long's team, so he withdrew from his cultivation, got up and opened the door to welcome them in.

After the two sides saluted, they each sat down, and one of the teammates named Qian Guan said, "Senior Brother Tang, we came here so early, didn't we disturb Senior Brother Cultivation, right?"

In fact, he was just a polite remark, because everyone knew that the effective cultivation time of the star person every day was only a few hours, and if he had good qualifications, he might be able to do a little more, but it would not be much more.

Therefore, star masters generally use the night time to cultivate, and during the day, they do various things to earn cultivation resources or make interpersonal resources, especially after reaching the level of their star saints, they can completely replace rest and sleep with cultivation.

Tang Chen shook his head with a smile and asked, "Everyone, is there something wrong with this morning?"

"It's not a secret, after a few of us saw the legend about the Ancient Dragon Palace by the lake yesterday, we became interested in it, so we all made an appointment and prepared to go to the lake to explore one or two, I wonder if Senior Brother Tang is interested in going together?" Qian Guan replied.

Tang Chen glanced at a few people, was silent for a moment, and said, "In my opinion, it is better for you to give up this thought as soon as possible." ”

"Why?" Qian Guan blurted out, with obvious surprise in his expression.

Tang Chen smiled and explained: "Look at you, when you hear the ancient ruins, you can't think normally, right? If you think about it a little more, it is not difficult for you to understand that if there is really an Ancient Dragon Palace at the bottom of the lake, it must have already been appropriated by others, after all, it has been so many years, how can it be left for you to explore?"

Qian Guan and the others glanced at each other and said with a smile: "This truth, we do understand, the reason why we want to explore is purely out of curiosity, wanting to see the appearance of ancient ruins, not to obtain rare treasures. ”

Tang Chen bowed slightly, indicating that he understood the thoughts of several people, but he knew very well in his heart, even if they didn't have the intention of exploring the treasure, it was impossible for those Star Saint powerhouses stationed on the shore of the lake to let them go to the lake, so everything could only be thought about......

Of course, he couldn't say these words, otherwise these people would definitely ask, how did he know that those Star Saint powerhouses by the lake were specially guarding the Ancient Dragon Palace, then he couldn't explain it.

"Well, since everyone has this curiosity, let's go and have a look. Tang Chen said.

Seeing Tang Chen agree, everyone applauded, the reason why they came to invite Tang Chen was to have more contact with him and further cultivate friendship, and on the other hand, to use Tang Chen's Star Array Technique.

In fact, they were similar to Tang Chen, after reading the introduction on the stone tablet by the lake yesterday, they curiously probed the bottom of the lake with their soul sense, but they were blocked by the isolation array and could not go deeper, they deduced from this that the bottom of the lake was probably protected by a high-grade star array, for the sake of safety, it was best to pull the master of the formation path to accompany them, and the best object in this regard was naturally Tang Chen.

After a few people agreed, they no longer hesitated, and rushed to the Hidden Dragon Lake on the spot, ready to enter the lake to find out.
