  Bei Feng's worry was not without reason. Nobody knew what the deal was with this underground space, or how it came to be. A faint tremor would travel over at intervals, causing one to feel more jumpy.

  The group did not speak, and traveled silently down the path. The only sound was the sonic boom caused by their speed.

  "From this point onward, we can only rely on ourselves to explore this place. From the ancient records, there are a total of one Void Gu realm cultivator and 19 Controlled Dan Heavenly Experts gone missing in this place. As for Xiantian experts, the skeletons of these experts are uncountable," the leader of the 12 Kunlun Devils said in a heavy tone. The numbers he gave were extremely terrifying.

  "That's right. This well opens up to many different paths, and we were not the only ones who chose this path. This was the path that was deemed to be the safest after compiling the efforts of countless earlier explorers. But no one can guarantee that this will not turn out to be the most dangerous path at the end."

  An effeminate voice rang out, causing the group of Controlled Dan Heavenly Experts to grow serious.

  "Flap, flap!"

  A series of wings flapping noises suddenly appeared from the distance. From the sounds of it, the speed was very quick!

  A golden-scarlet bat about the size of a stone mill appeared from the corner, charging right towards the group!

  This was just the beginning. In the blink of an eye, countless bats swarmed over out of the corner!

  "Chi, chi!"

  "Ah!"

  "Quick, kill these bats!"

  An endless rabble of high-pitched screeching above the range that the human ears could detect flooded into the heads of everyone. This kind of sound was like the sound of a nail on a glass magnified thousands of times!

  One or two bats would not affect a Controlled Dan Heavenly Expert at all. But if it was a few thousand or tens of thousand of bats screeching together, the combined might of these weak sound waves would form together into a shocking noise!

  Even the zhenqi barriers around the experts were not able to offer the slightest bit of resistance! The combined sound wave was like a sharp sword, directly penetrating into the minds of everyone.

  "Dragon Subduing, Tiger Suppressing!"

  "Three Thousand Realms!"

  "Space Shattering Fist!"

  When the group finally reacted, numerous large-scale area-of-effect martial techniques were blasted towards the bats without pause!

  These techniques might not be the experts' strongest abilities, but they had the widest area of effect. Normal bats could already dodge common attacks aimed at them, not to mention these variant bats.

  When these bats detected the attacks flying at them, they instantly tried to dodge. However, the space in the underground passage was only so large. No matter how they tried to run, it was impossible to block these attacks that covered the entire area!

  "Peng, peng!"

  Countless bats were directly smashed apart in midair. Their black-colored blood splattered on the ground, giving off a faint smoke. Numerous small pits appeared on the ground, fully displaying the corrosive properties of the blood.

  Of the many Controlled Dan Heavenly Experts, quite a few of their faces were pale and dull. This was naturally not a result of being scared by the bats. Instead, it was the direct effect of being injured by the bats' attack on their mental energy!

  Bei Feng's mental power was strong and plentiful, so this level of attack was not much to him. But Bai Xiang and Mystic One were not in such a good condition. As for the Cerberus, it was completely fine.

  "Place this leaf in your mouth and suck on it."

  Seeing the state of the two, Bei Feng took out two pieces of crisp green leaf from his spatial ring. These two leaves were only as big as a fingernail and a strange fragrance rose from them, causing one's mind to perk up.

  These leaves were similar to the tea leaves on earth. It was bitter to the tongue but had a sweet aftertaste. They were very useful for increasing mental power.

  But the leaves only had a strengthening effect on mental power the first time they were used. Subsequent uses on the same person would not have any effect on increasing mental power, but it could allow one to recover their mental power, or gently heal any damage to the mental power.

  Bai Xiang and Mystic One did not delay and directly placed the leaves into their mouths. A strange energy immediately seeped through their oral glands, turning into an ice-cool draft that flowed into their sea of consciousness!

  In a mere instant, the two's pale complexions turned rosier. As for the others, Bei Feng was sympathetic but unable to offer any aid. These leaves were something he'd managed to fish up from the Myriad Worlds. There were only eight pieces, and it just so happened that only two were left now.

  Now that they'd gone through this lesson, everyone's hearts became many times more vigilant. Fortunately, they'd come here with tens of Controlled Dan Heavenly Experts. If it had been just one or two Controlled Dan Heavenly Experts, they would have died for sure under the attack by the bats!

  These bats had very weak individual strength, and could not even be compared to a Grade 1 Demonic Beast. But their strange combined ability gave them enough strength to kill even Controlled Dan Heavenly Experts!

  This incident caused the group to finally grow serious. This place was the underground tunnels beneath the Locking Dragon Well and not the outside world. If they still maintained their arrogant and careless attitude, they might really die in here!

  The group rested for a moment and continued forward. As they turned the corner, several tens of yellowed bones appeared in their sight. Judging from the state of the bones, their owners must have died many years ago already. Most likely, they had all died by the surprise attacks of the bats.

  No one would stop here for the sake of these failures. Which one of those here did not have their hands covered in blood? Unless they were relatives or had close connections with the dead, it was very hard to cause any ripples in the hearts of these cultivators.

  The walls on the sides of the tunnel had become tougher and tougher the further in they went. It was no longer just normal rocks, but mineral-filled ores!

  "Ka-cha!"

  The group stepped into an area that was not even ten square meters wide. When they raised their heads and looked up, it seemed like they were walking upwards, but when one of the experts stepped foot into the area, a cracking sound appeared under his foot.

  Numerous cracks appeared from under the Zeng Clan Controlled Dan Heavenly Expert's foot, spreading outwards in all directions.

  "Interesting!"

  "Pa!"

  A smile appeared on Zeng Zhiheng's face as he directly smashed his foot heavily downwards!

  Suddenly, the thin rock layer collapsed directly, revealing the bottomless cave below, while Zeng Zhiheng was firmly standing in the air.

  At this time, everyone was feeling extremely exasperated. They still needed to travel further down?! This was like an endless journey downwards!

  But for the sake of the Dragon Imprisoning Chains, everyone could only harden their scalps and accept the situation as they all jumped down.

  When they reached the bottom, several more minutes had passed. By Bei Feng's estimation, they were already several ten thousand meters underground right now. Perhaps that estimation was not even close to the real number!

  The group stood above a small reservoir of water, looking at a little gap at the side of the walls. One of the experts walked up and took out a half meter long short sword, wedging it into the gap and forcefully widening it.

  The group stepped into the gap. As expected, there was another passageway not far away.

  "Look here!" someone cried out and pointed at two sections of metal chains on the ground. However, this section of the chain was broken.

  "Looks like our direction was not wrong. Following these two chains, we should be able to find the Dragon Imprisoning grounds!"

  An excited smile finally appeared on the emotionless faces of the group.

  An incomparably huge boulder sat in middle of the path. The group tried to pull the chains out from under it, but realized that the chains were completely stuck beneath it. From the looks of it, the boulder was not here originally, but perhaps due to some tectonic earth movements, this huge boulder ended up crushing down on the chains and blocking the road.

  The temperature at this area was very high, much higher than what normal people could endure. However, this intense heat did not seem to have any effect on the group at all.
