The entrance to the Underground Passage is in an unnamed valley at the bottom of the mountain range.

From a distance, Gu Chengcheng saw a large black cave entrance at the end of the valley.

In the valley, there is a large gathering place of monsters, such as the Sinking Demon, the Blade Demon, the Hungry Dead, the Skeleton, the Dark Hunter, ......

There are many monsters active in the valley, making the not too big valley feel like a market, which can be regarded as "people coming and going", and it is very lively.

It's just amazing that even the entrance to the large cave sits at the end of the valley, and the monsters roaming around the valley are oblivious to it.

And every time a monster approaches the entrance to the cave, it seems to have a force that makes it change its route or simply turn around and go back.

As Gu Cheng appeared at the mouth of the valley, the atmosphere in the valley couldn't help but become more lively.

The monsters in the valley waved the scimitar spears in their hands and expressed a warm "welcome" to Gu Cheng's arrival.

In the face of the monsters' "warm welcome", all Gu Cheng could respond to was large fireballs and small fireballs.

The dense environment of monsters in the valley gave Gu Cheng a better space for the big fireball to play, and the explosion plus splashing, often a small piece of monsters was cleared when a big fireball went down.

As one big fireball exploded after another, when the mana was not enough, he used a few bottles of mana potions, and immediately continued to throw fireballs.

Clean up all the monsters in the valley and pack up the loot.

Gu Cheng took a torch and went straight into the cave.

The underground passage is different from the mysterious cave where Gu Cheng killed the corpse and set it on fire, the mysterious cave is more of a naturally formed sense of desolation, while the underground passage may be because there are more people who have passed back and forth, and there are many more artificial traces than the former.

It's just that as a long time passes, many traces in the passage have weathered away with time.

As the only passage that once connected the outer area and the three low-level areas, the advantage of the large number of people who had passed through it was that every time he encountered some forks in the underground passage, Gu Cheng almost didn't have to think about how to choose, and just went directly to the hole with the heaviest human traces.

In the underground passage, Gu Cheng also encountered many monsters,

It was clear that as the distance from Rog's camp got farther and farther away, the level of the monsters encountered slowly increased.

For example, the monsters in the Stone Wilderness are obviously higher in level than the monsters in the Icy Plains and the Blood Wasteland before, and at this time, the monsters in the underground passage have risen a step higher than the Stone Wasteland.

As Gu Cheng advanced, a team of evil hunters rushed over from a distance.

The Evil Hunter is an upgraded version of the Dark Hunter, except that the pitch-black leather armor has been replaced with brown and yellow, and the attack power and health are a little higher.

It's the same when they see the enemy, they rush up and beat them.

There is also the crippled monster, this is another new type of monster that Gu Cheng encountered in the underground passage, this black monster elder has a head like a buffalo, two long horns are slanted up on both sides, and a mouth that exudes a foul smell has been dripping with saliva all the time.

As a demon that relies on electric elements to gain strength and recovery, it moves slower than other monsters.

Because of its slow movement, the Cripple gains the ability to release visible electro-attack effects and absorb a certain amount of damage.

But that's not the limit for the cripples, who will turn around and run away whenever they encounter an opponent they can't beat, and if someone continues to pursue, the cripples will turn around and cast lightning balls from their mouths.

As for the lightning ball, although the damage is relatively high, this is not the reason why Gu Cheng was afraid when he faced the crippled monster.

The reason why Gu Cheng was worried was because this kind of monster was basically at least six or seven together every time it appeared.

When he couldn't beat it, six or seven lightning balls erupted at once, and after he was hit, anyone among the low-level professionals had to kneel.

Fortunately, there were many crooked paths in the underground passages, and by constantly dodging into the surrounding passages, Gu Cheng dodged the high-intensity lightning ball that was the last of the crippled monsters, and then the fire bomb sent it away.

After walking in the underground passage for more than two days, after Gu Cheng killed a group of monsters he encountered, the exit of the underground passage finally appeared in front of him.

This is because Gu Cheng has walked in the passage a few times, so he knows how to walk a lot of forked roads, otherwise it is estimated that this will still be wandering around in the underground passage.

However, perhaps because of the wrong location and marking, when Gu Cheng entered the exit of the underground passage he found before, he found that what he had entered was not the exit from the underground passage at all, but the passage to the second layer of the underground passage.

However, with the idea that it would be a monster farm anywhere anyway, Gu Chengcheng cleaned up the entire second floor of the underground passage.

Except for an elite-level skeleton monster, none of the other higher-level monsters were found.

And this boss-level elite skeleton only burst out a few gold coins.

Such an explosion rate did not make Gu Cheng strange at all.

In fact, sometimes Gu Cheng also thinks that such an explosion rate is normal now, compared with the previous explosion rate and the explosion rate before rebirth, such a high explosion rate before made Gu Cheng feel a little worried in his heart, such luck is how much luck is overdrawn in the future.

By the time Gu Cheng came out of the underground passage, it was already three days later.

The monsters in the underground passages are generally stronger than the monsters in the stone fields, and when you kill them, the experience points you gain will naturally be higher.

Counting the monsters killed in the Ice Plains and Stone Wilderness before, and the experience points contributed by the monsters in this underground passage, Gu Cheng finally rose to level five.
