I saw a hole with a diameter of about three or four meters not far from the two of them, with light seeping out of it.
The water in the pool couldn't flow in, it was obviously blocked by the barrier, and Ling Hao could sense the slightest wave of formations at the same time.
"That should be the entrance to the hinterland!" Wen Renliying pointed at the entrance of the cave and said.
"Yeah!" Ling Hao responded.
"Ling'er, the source of the spiritual vein is already spiritual. If it wants to hide, it will be difficult to find it." Wen Renliying continued to speak.
"After you enter, activate your bloodline power and walk around to see if you can establish some kind of connection with it."
"Peak Master, why do you think I can establish a connection with the origin of spiritual veins?" Ling Hao asked.
He wanted to ask this question a month ago, but he didn't find a suitable opportunity at that time.
The source of this spiritual vein is the essence of heaven and earth that has been condensed over countless years. How it can be connected with the blood in his body is beyond him.
"I don't know about this question either!" Wen Renliying shook her head.
"But since senior brother asked you to do this, he must have a reason. You can ask him in detail next time you meet him."
"According to my preliminary estimation, it should have something to do with your physique and bloodline!"
"Okay!" Ling Hao shrugged his shoulders.
"By the way, although the formation above the lake is turned on, it will automatically turn off again after a month at most." Wen Renliying continued.
"So, you can only stay in there for a month at most. Once the time is up, even if you haven't found the source of the spiritual veins, you have to come out quickly."
"Otherwise, you'll be trapped inside!"
"Is there such a thing?" Ling Hao was stunned for a moment.
"Yeah!" Wen Renliying responded: "Okay, go ahead, I'll wait for your news above!"
"Okay!" Ling Hao responded, formed a barrier on his own and walked towards the entrance of the cave.
To his surprise, after arriving at the entrance of the cave, he easily passed the barrier and entered the cave.
Seeing that Ling Hao had entered, Wen Renli Ying turned around and left.
Later, after Ling Hao withdrew the barrier, he followed the passage downwards and walked in the air.
Not long after entering, the passage became much wider, with a diameter of about fifteen or six meters, winding down.
He could clearly feel that the aura inside was a bit richer than outside, and he felt relaxed and happy while breathing.
It was much richer than the spiritual energy in his spirit gathering array.
This passage was very long, and Ling Hao felt that he had been flying in the air for almost twenty minutes, and he still hadn't reached the end yet.
Along the way, there was nothing unusual except that the spiritual energy was getting stronger and stronger.
After another ten minutes or so, we finally walked through the entire passage.
"Um?!"
After arriving outside the passage, Ling Hao couldn't help but be surprised.
What appeared in front of him was a huge underground space. Because he couldn't see the end at a glance, he didn't know how big it was.
In the space, in addition to strange-shaped stalactites, there are some unnamed trees and vegetation.
In addition, there are two or three small pools within sight, and there is a slight chill on the water.
Ling Hao also noticed that the concentration of spiritual energy in this space was two or three times stronger than that in the passage, and he felt refreshed while breathing.
After slightly adapting to the light inside, Ling Hao released his mental power to investigate.
After about two minutes, he recovered his mental power. What he could determine was that there were no living things in this space except plants.
Then, Ling Hao walked forward aimlessly.
Along the way, he saw several fruit trees with many unnamed spiritual fruits growing on them.
Other than that, nothing was found.
Time passed quickly, two hours flew by in the blink of an eye, and Ling Hao still didn't notice anything unusual.
