Chapter 2020: Mysterious lake

  It seems that this small lake is formed by water drops from stalactites.
  Drips of water pierced through the rocks. I don’t know how long it has existed here, so that the dripping water droplets from above have knocked out such a large depression on the ground and formed a small lake.
  Xia Ruofei and the three did not feel any danger here, but they still did not dare to take it lightly. Xia Ruofei always maintained a state of divergent mental power, looking around while being careful.
  This stone cave is very quiet. Except for the ding-dong sound of water drops falling on the lake surface after a while, there is basically no sound. The sound of the three people's footsteps echoes in the cave, and it feels very empty.
  Xia Ruofei thought to himself: The senior copper coffin pointed out this cave specifically, what is the chance?
  The situation inside this cave is almost unobstructed, except for the stalactites and the small lake below, which is the rugged rock wall, nothing else can be seen.
   And Xia Ruofei also used mental power to investigate carefully, there is no wave of formation here.
  In addition, there may be places where there may be news from the agency. Xia Ruofei also carefully checked with mental energy inch by inch, and found no abnormalities.
  In other words, the possibility of formations and organs can basically be ruled out here.
  Of course, unless this formation or mechanism can hide Xia Ruofei's eyes.
Xia Ruofei took Song Wei and Ling Qingxue beside him, and began to walk along the cave wall and around the small lake to check for a little bit. Sometimes mental power detection is not omnipotent, especially in some hidden and suppressed mental powers. In places, the naked eye is more useful.
  However, the three of them did not find anything after turning around.
  Xia Ruofei cast his gaze on the small lake. Since everything seems to be normal, the only variable that may exist is this small lake.
  In fact, when Xia Ruofei first entered this cave, he first focused on this lake.
  However, he scanned it with mental power and found that it seemed to be ordinary lake water, and there was nothing special, so he put it aside for the time being to investigate the surrounding environment first.
  Now that no clues were found around, Xia Ruofei naturally focused on this small lake again.
  He carefully inspected the lake water again, but still did not find anything special, it felt like ordinary water.
  However, when he wanted to investigate the situation at the bottom of the lake, he immediately felt something abnormal. The suppression of the mental power by the lake was extraordinary, and the mental power could not go deeper.
  Xia Ruofei immediately became energetic.
  It is necessary to know that his mental power is already comparable to that of a middle-age cultivator. At this level of mental power, he can't go directly to the bottom of the lake, which is very abnormal in itself.
  Xia Ruofei did not increase his mental strength, forcibly inspecting the bottom of the lake.
  He turned to continue to analyze the lake.
  The water of this lake looks very clear, colorless and tasteless, and it did not show any unusualness under the investigation of mental power.
  If there is no problem with the water of the lake, then something at the bottom of the lake suppresses the mental power.
  But Xia Ruofei didn't ignore the lake water directly, but took a closer look again. Even if he didn't see any abnormalities, Xia Ruofei didn't take it lightly.
He thought for a while, and simply ingested a silver carp from the rushing river in the mountains and seas of the Lingtu Space. In the Lingtu Space, it is not only the sea that breeds all kinds of fish, shrimp and crabs, but also the river. Some freshwater organisms are also cultivated.
  Xia Ruofei inspected the lake water and knew that it was fresh water, so I just got a freshwater fish to try.
  Xia Ruofei thought, this silver carp was taken out of the spiritual map space by him, and directly thrown into the small lake in front of him.
  Song Wei and Ling Qingxue couldn't help but secretly be surprised when they saw Xia Ruofei directly took out a live fish from the space magic weapon.
  They also know that magic weapons such as storage rings cannot store living things. Even if living things are put in, they will die instantly.
  However, they were used to Xia Ruofei's repeated miracles, so they didn't think too much. Maybe Xia Ruofei's storage magic weapon is special, maybe he used formations to protect these living creatures. After all, his formation level is extremely high. In short, there are many possibilities. In their opinion, as long as Xia Ruofei wants to Things that can't be done.
  So they quickly focused on this fish.
  I saw this silver carp entering the lake water, as if it had been beaten with chicken blood, suddenly became extremely excited, and with a flick of its tail, it dived into the depths of the lake.
  However, this silver carp hasn't swim far yet, and everyone can still see it clearly through the water with naked eyes. At this moment, the silver carp burst open without warning...
