Dong Yu pulled Su Di towards the entrance of the underground palace, and said to Su Di with crying and grief.

"Su Di. The monsters in this dungeon are endless, and after killing this wave, it will be refreshed immediately after a few minutes, and it won't be killed at all! ”

"The only way is to completely seal the dungeon so that they can't get out!"

"My brother will drag the next wave of refreshed monsters here, let's get out as soon as possible, you are an outsider, there is no need to stay here and die!"

After Dong Yu finished speaking, she glanced back at her brother, who was waiting for the monster to refresh at the entrance, and this farewell was goodbye.

"Brother!"

Dong Yu's words, Su Di has heard it countless times, and even the life and death between their brothers and sisters, Su Di has seen it countless times.

After all, when he cleared this secret realm in his previous life, Su Di didn't know how many times he was tortured, and Su Di had already memorized the plot.

He knew very well that if he followed Dong Yu out now to completely seal the underground palace, then his trip would be in vain, and he would not be able to clear the secret realm with all his efforts.

And the only way is to prevent monsters from refresh without sealing the dungeon.

And the crux of the problem is precisely in the depths of the underground palace.

As if he hadn't heard Dong Yu's words, Su Di said flatly.

"I have a way, so that your brother can not die, you can come with me as soon as possible now!"

Dong Yu was stunned for a moment, then immediately became overjoyed and asked urgently.

"Su Di, do you really have a way to save them!"

Su Di walked a little further forward and came to a fork in the road, he pointed to the road below and said.

"You follow me now, go down as soon as possible!"

Dong Yu saw that Su Di was actually about to enter the bottom of the underground palace, and hurriedly dissuaded him.

"Su Di, there is a labyrinth down here, there is no end at all, we have sent many people down before, but we can't get out at all!"

Su Di didn't explain anything to Dong Yu, but walked forward, it was just a maze, and it was not a big problem for Su Di now.

He has so many demon hunting dogs in his hands, it should be a simple matter to let these demon hunting groups be responsible for finding the exit.

Dong Yu hesitated for a moment, seeing that Su Di was about to enter the labyrinth, her heart fell into a deep entanglement again, should she follow Su Di down?

Su Di said that she could save her brother, of course she was willing to follow, but the problem is, if Su Di failed and the plan failed, wouldn't her brother die in vain?

"This!"

Just when Dong Yu hesitated, Su Di had already disappeared into the depths of darkness, and there was no movement at all.

Dong Yu gritted his teeth, seeing that Su Di is so confident, and his combat ability is indeed strong enough, then believe Su Di again.

"I'll do it too!"

Dong Yu quickly followed.

Su Di took Dong Yu and continued to walk towards the depths of the underground palace, which was still a staircase with no end in sight, as if leading to the abyss of hell.

And the various monster carvings carved on the surrounding walls seem to come to life.

After walking a few steps, Dong Yu couldn't help but shudder, she had never gone so deep into the ground.

"Su Di... Have you been here before? ”

Su Di smiled, in the depths of this labyrinth, I don't know how many times I have been here in my previous life, I used to rely on a large number of people to barely enter the deepest depths, and it was the first time to come in alone.

"Nope!"

Dong Yu swallowed hard and said to Su Di.

"Su Di, I advise you not to go down, there's nothing down here, it's just a labyrinth!"

"When you see these endless stairs in front of us, it's like we're spinning in place, it's a labyrinth!"

Su Di smiled and nodded, he also knew that this was a maze, and it was difficult for one person to get out.

In the previous life, many people went down together, and only by forming a human chain could they pass.

But now there is no need, Su Di already has a way to deal with it, I saw Su Di snap his fingers lightly, and more than thirty demon hunting dogs were summoned.

"Go!"

Although the fighting ability of these thirty or so demon hunting dogs is not strong, their sense of teamwork is quite powerful, and their noses are quite sensitive and extremely sensitive to smells.

It is very simple for these three demon hounds to work together to mark the road, find the exit, and keep the way they came.

Under Su Di's order, the thirty or so demon hounds began to gallop forward, and every time they reached a critical juncture, they would leave some smell in this place.

With the uninterrupted cooperation of more than 30 demon hunting dogs, the staircase maze in front of him was finally found by Su Di.

"Let's go."

Dong Yu was blinded, but he didn't expect Su Di to have such a pet beast, and there were so many of them.

"Su Di... You're too capable! ”

"You can manipulate so many pet beasts!"

Just when Dong Yu was surprised, a red light suddenly flashed at the end of the passage, and a cold, as if it was going to tear everything apart, suddenly galloped in.

Dong Yu didn't have time to react at all, he felt that this scorching power had come to his nearness, and he was about to die.

"Roar!"

There was another roar of the giant bear, and the huge body of the thundering giant bear suddenly rushed to the front, using its own defense to block this attack!

"This!"

"Su Di, what is this?"

Dong Yu also came to the depths of the maze for the first time, and he didn't know what it was at all.

"Su Di's power is so weird?"

Su Di said with a solemn face.

"That's where those monsters come from!"

As soon as Su Di's words fell, the thundering giant bear rushed towards the red light in front of him.

The Thundering Bear's own defense is sufficient, and this red light can't tear through the Thundering Bear's defenses at all.

Soon the Thundering Bear rushed to the side of a red crystal, brandished a huge bear paw, and began to strike violently.

"Boom!"

Every time the bear's paw slapped, the entire dungeon trembled violently.

But the two sides fought for a while, and the Thundering Giant Bear was not injured, but the shell of the red crystal seemed to be extremely hard, and the Thundering Giant Bear could not break through the defense.

Su Di bit his lip and released the Winged Tiger again.

The reason why he didn't release the Winged Tiger in the first place is simple.

As a top-level hunter, the Winged Tiger's defense is not comparable to that of the Thundering Giant Bear, and it would not be good if he was injured by the red light.

And there must be other monsters guarding this crystal, but the thundering giant bear has been smashed for so long, and the other party has not shown up.

Su Di was worried that the other party would attack suddenly, so he kept controlling the Thundering Giant Bear and did not make a move, just to make a preemptive attack.

But now it seems that the Thundering Giant Bear can't break through the crystal's defense, so he has to release the Winged Tiger.

However, for the sake of insurance, Su Di still released the demon hunting dogs and attacked them in groups.

In this way, the power released by the red crystal will be completely absorbed by the black bear and the mad dog, and the winged tiger will not be injured.

And the mist worm was also summoned by Su Di and slowly flew out.

However, the tail of the misty insect did not flash, did not release skills, but quietly hid around like a small bug.

More than thirty demon hunting dogs, Wu Yang Wu pounced towards the crystal, the red light flashed, and the several demon hunting dogs led by them were torn apart in an instant and turned into invisible.

The Winged Tiger hiding behind seized the opportunity to pounce forward, and its blood-red claws smashed directly on the shell of the crystal.

"Roar!"

The Winged Tiger itself has its own defense-breaking attributes, coupled with Su Di's blue suit effect, the hard crystal shell was smashed open in an instant.

"Boom!"

The entire dungeon began to shake violently, and the rocks collapsed, as if everything was going to be buried.

At this moment, above the red crystal, a pair of red eyes suddenly opened, and then a gust of yin wind suddenly rose, and a pair of sharp claws rushed towards the Winged Tiger.

Su Di's eyes widened, and he quickly inspected the panel of this monster.

【Night Bat King】

[Level: 11]

[Level: Boss Level]

[Constitution: 28]

[Strength: 57]

[Spirit: 30]

[Dexterity: 62]

Su Di was stunned for a moment after seeing the attributes of this boss, the agility attribute of this boss was even stronger than Su Di's memory, it was so exaggerated, a few points more than the Winged Tiger.

Although the mental and physical attributes are a bit biased, the agility attributes are really amazing.

"Roar!"

Winged Tiger also realized the danger and wanted to dodge, but his body was lying on top of the crystal, and the opponent's agility was not high, so Winged Tiger didn't have time to dodge at all.

"This!"

Seeing that the blood-red claws were about to smash on the Winged Tiger, Dong Yu closed his eyes nervously.

"Su Di..."

Dong Yu closed his eyes, not daring to look at the bloody picture in front of him.

However, she waited for a moment, and there was indeed a scream, but it was not the roar of the winged tiger, but a very sharp and piercing howl!

Dong Yu hurriedly opened his eyes and found a huge bat pinned to the ground by the winged tiger.

The Thundering Bear, which was attacking the Crystal, also changed its target and rushed over with a roar.

The huge bear claws smashed into the bat's head, shattering the bat's head in an instant.

"Ahh
