Du Mu looked up.

The first thing that catches your eye is a huge and hideous head like a house, with distinct lines on the dark skin, reflecting a cold glimmer under the fluorescent light.

Beneath the skull is a black body curled up like a hill and muscular limbs.

It was a terrifying creature that resembled a lizard in appearance, but was hundreds or thousands of times larger than a lizard.

Du Mu swore that he had never seen such a huge creature, even if it was entrenched, its height had reached twenty meters, and standing in front of it, a sense of insignificance arose.

The monster, let's call it a lizard troll, seemed to be asleep, its eyes closed, its mouth slightly open, and visible air coming out of its mouth.

The fishy cool breeze that Du Mu felt in the passage before was the air flow brought by it when he breathed during sleep.

Even though it was more than twenty meters away, the palpitations and fear in Du Mu's heart were still surging like a flood, reminding him of the horror of the monster in front of him.

After a long time, Du Mu's stiff limbs regained a trace of feeling, and he moved his steps slightly, intending to retreat into the passage, but out of the corner of his eye, he caught a glimpse of a passage entrance on the opposite side of the cave.

Suddenly, he stopped, hesitating.

What to do?

If you go back, you will only have to climb the stone wall and go up, not to mention whether you can do it, but you are afraid that you will work hard to climb to the top, and there may not be an exit to leave.

But if you continue to explore and reach the entrance of the passage, you will have to pass by the lizard troll, which may wake it up.

Wake such a terrible beast from its slumber, and the fate is self-evident!

After hesitating for a long time, Du Mu decided to take a risk.

After all, the first road is a desperate situation no matter how you look at it, and the second one still has a glimmer of hope to get out of trouble, although the risk is not small.

After thinking for a few seconds, before acting, Du Mu took out the Harmony Glasses from the dimensional house and put them on.

"Harmony glasses have the effect of completely covering the breath, wearing this, the success rate should be greater!"

Taking a deep breath, Du Mu cautiously moved his steps and walked towards the entrance of the passage opposite.

From where he was to the entrance of the passage, there was a distance of more than three hundred meters.

In normal times, Du Mu can run without even a minute, but now he can only move forward at a turtle speed.

The lizard monster slept quietly, as if it didn't notice that there was an uninvited guest in the cave, and the strong wind brought by his breath set off a slight whistling sound around him, which just covered up Du Mu's footsteps.

After walking in fear for nearly ten minutes, Du Mu finally moved to a place not far from the passage.

Seeing that he was less than twenty meters away from entering the passage, he turned back to catch a glimpse of the lizard troll, only to find a pair of eyes with larger pupils than him staring straight at him.

In an instant, Du Mu's body froze suddenly, his heart beat violently, and a strong sense of fear gradually rose from his heart, like a crazy vine, instantly grabbing him, making him cold, and his hands and feet were a little disobedient.

The lizard troll's eyes widened, staring at Du Mu for a few seconds, and then suddenly opened its mouth wide and let out a deafening roar.

A terrifying roar echoed through the cavern, and there was a faint feeling that the whole cavern was shaking, causing a large amount of rubble to fall from the roof and stone walls.

Two rows of huge and sharp teeth spread up and down, as if they were about to bite Du Mu in the next moment, crushing him and swallowing him into his abdomen.

The feeling of death was so close, and when the lightning was blazing, Du Mu's heart suddenly flashed, his wrist flipped, and there was a fat happy chicken with a fragrance between his palms, and he threw it into the lizard troll's open mouth with a flick of his hand.

The fat happy chicken, which is only the size of a basketball, looks so small compared to the huge mouth of the lizard troll.

However, the moment it fell into the mouth of the lizard troll, the latter, as if unable to resist the temptation of the fragrance, closed its mouth and swallowed with a grunt.

In the next second, under Du Mu's shocked gaze, the lizard monster's raised head was slowly lowered, and its huge body fell back to the ground again, its originally hideous and tyrannical eyes narrowed, and the corners of its eyes bent down to the sides, as if it looked happy.

This scene made Du Mu stunned for a moment, and then his face was ecstatic.

Unfortunately, within a few seconds, the lizard monster reacted, raised its head again, and roared at Du Mu with its mouth wide open.

Seeing this, Du Mu hurriedly took out the fat house happy chickens again, and threw out two at once this time, extending the time for the lizard monster to be happy for more than ten seconds.

As a result, strange feeding behaviors were staged in the gloomy caverns.

As Du Mu fed, the lizard monster's head was raised and lowered, its mouth opened and closed, and its emotions switched back and forth between anger and happiness, which lasted for seven or eight rounds.

In the end, Du Mu simply threw all the three treasures of the fat house happiness into the lizard troll's mouth.

"Makes you happy!"

At this moment, the lizard troll collapsed to the ground like mud, apparently completely immersed in happiness.

Taking advantage of this opportunity, Du Mu hurriedly turned around and ran away, rushing towards the passage not far away.

As soon as he entered the passage, he immediately took out the lamp to illuminate it, and after running for hundreds of meters without stopping, he heard an earth-shattering roar from behind.

"The combination effect of this Happy Three Treasures is a bit strong, even the lizard monster that looks so powerful has been lost for almost half a minute!"

Du Mu, who was running wildly, sighed, and then remembered that he left in too much of a hurry and forgot to use the detector to check the combat power of the lizard monster.

"It must be far more than a three-star martial artist!" Du Mu said secretly,

The aura of the lizard troll, and the sense of oppression that gave him, far surpassed that brought by Du Shuang, who was the best of the three-star martial arts.

"I hope there's a way out of the way, I don't want to turn back and face that monster!"

Recalling the experience of being deprived of his ability to act by fear just now, Du Mu hit him hard.

Like the previous passage, this one is also very lengthy now, and Du Mu has walked nearly two hundred meters before he reaches the end.

"It feels like an underground labyrinth. He was a little surprised and confused, "But it's a labyrinth under town...... Let's not talk about the foundation, could it be that no one in Guyan Town has ever discovered the caves and passages underneath?"

Du Mu was puzzled, but at this time, the passage finally came to an end, and a silver door blocked the way forward.

By the light of the lamp, Du Mu carefully looked at the door for a while, and it was smooth, except for a hole in the middle, which should be a keyhole from the appearance.

Touching the door, the unique coldness and hardness of metal came through his fingertips, dispelling Du Mu's idea of breaking the door violently.

Sighing softly, he took a few steps back, staring at the metal door in deep thought.

"How do you open this door?"
