Dark night, Graham Castle.

The wind is howling.

Rain like a bet.

Lightning bolts pierced the air, illuminating the black Gram Castle as if it were day.

The storm washed away the old walls and castles, and the rain on the towering walls and the spires of the buildings fell like a waterfall under the waterfall, forming curtains near the eaves and sewers, reflecting the white light in the lightning.

The swift rain poured into the moat around Graham Castle, and the white waves rolled up layer by layer, and the dusk water flooded the river, widening the river like a white horse.

Under the storm, even the strict patrol team of Graham Castle left the city wall and hid in the watchtower to take shelter from the rain, the pouring rain also paralyzed their nerves, and the night duty and patrol that were essential every night were also much lax, they shrank in the corners one by one, or looked up at the sky, or chatted and fart, but no one would notice that there was no one under the castle and near the moat.

One of the reasons was that the gloomy weather blocked the view, and the other was because the heavy rain affected the appearance of the people, and there was no one in the castle before, and the castle of Graham had been peaceful for several years, and no one dared to make trouble under the butcher of the bloody hand.

It is precisely because of these three reasons that they are completely relieved, and no one would have thought that someone would take action in such bad weather.

"Boss, should we go out on patrol?" Rojas, a soldier of the garrison, timidly asked Aquino, the leader of the first squad of the garrison who was on duty at night.

"Boy, it's raining so hehe, hehe, how could anyone come to Graham Castle to make trouble? And Lord Count and Master Makola have already gone out and are not at home, hehe, in this way, we don't have to go out on patrol, as long as we don't let the thieves sneak up on the city wall and cause trouble. Aquino was experienced, so he naturally knew that marching on a rainy night and attacking the castle would be as difficult as climbing to the sky, and he didn't believe that anyone who dared to come to Graham Castle to cause trouble, so he automatically gave up monitoring under the city walls, which also reduced the danger of Enlina's team a lot in disguise.

Although the patrols have decreased, in fact, the defense force of Graham Castle has not weakened much, in some key places, a group of cloaked Shadow Organization members are waiting there, and Makola deliberately transferred the power of the Shadow Organization back and concentrated around the city wall, so that the defense force of the entire city wall is like an iron wall.

It can be said that if Enlina's team chooses to break through the city wall, then they will be like climbing to the sky, and there is no chance of success at all.

However, due to the relationship between the internal response, they were very lucky to avoid this layer of defense.

The road was muddy, the thunder roared, and in the torrential rain, unexpectedly, a masked team suddenly appeared outside the castle.

The twelve people quickly touched the vicinity of the moat, although the heavy rain made the garrison of Graham Castle lose their vigilance, but it also caused unnecessary trouble to Enlina and others, such as the location of the drainage outlet became the first problem.

Enlina and the vice-captain Blatt were the first to touch the moat, the turbulent water made it impossible for them to determine the location of the drain, and the two of them did not dare to use magic lamps to illuminate them for fear of startling the grass and snakes, which gave the two of them a problem for the boss.

"Blat, what should I do?" Enlina frowned, she didn't expect that the first step of the rescue operation went wrong.

"Well, Boss, let's go into the water and see, Carol, get ready to go into the water, you're good at the water, pay attention to the drain into the castle." Blatter knows the characteristics of these players very well.

"Okay, Captain Blatter." Carol quickly took off her coat and tucked it away in her storage ring, everyone was perfectly prepared as she had already known to enter the castle through the drainage system of Gram Castle.

They were all covered with black coats and robes on the outside, and animal skins on the inside. This kind of water is actually a one-piece diving suit made of fish skin, sea Jiao skin or shark skin, which only exposes the eyes, nose and other organs, and the surface is smooth and warm, so that it can swim faster and swim longer in the water.

Carol took out a mask and put it on his face, this mask is round, like a sealed cover, covering the person's face, which can make people breathe for a short time, and at the same time, it will not affect the sight of the person in the water, clean up, he plunged into the water with a fierce son, his water nature is really good, just swam back and forth in the water for a few rounds, he came out of the water, beckoned to everyone, and told them that they had done it and could act.

This made Enlina and Blatter, who were a little nervous, and many team members, feel at ease, so they sorted out their equipment and began to go into the water, Ilan also put on the water back, took out the mask from the space ring, and put it in front of his face, he breathed a little, this mask was a little aggrieved, but it was still possible to dive underwater in a short time.

The group quickly dived into the moat, and Enlina made a departure gesture to Carol, so Carol rushed into the sewers like a mermaid, and then Enlina and the others followed, while Blatter stayed behind the back hall. The water potential of the drainage pipe is very turbulent, and the process of moving forward is very difficult, but fortunately, there is no weak person among the twelve people, and this difficulty is not difficult for them. After swimming about thirty or fifty meters forward, Carroll stopped, and the others who followed followed. Twelve people were crammed into the somewhat narrow drainage channel, which seemed very crowded.

At this time, since they entered the underground, they no longer had to worry about startling the snakes, so several magic lamps were lit, and the dim light illuminated the scene ahead and made it clearly visible.

Carol waved his hand to everyone, only to see a huge iron fence in the way, stopping Carol's steps, Enlina swam ahead, and he took out a sharp one-handed knife "Celestial Knife" from the ring, which was a gold-level weapon.

Blade of the Firmament, Perfect Tier Equipment, Durability: 152/152, Strength plus 21, Agility plus 17, Spirit Plus 14.

Enlina pulled it out of the scabbard, and the snowy blade drew a silvery-white brilliant arc, and with a bang, the Celestial Knife slashed above the iron fence, however, surprisingly, the expected phenomenon of the iron fence being split did not happen, but the Firmament Knife rolled up, and a wide opening appeared in front of everyone's eyes, if it wasn't in the water, it must have been an exclamation.

However, although he could not speak, the disappointment in the eyes of everyone was self-evident.

The team members were dumbfounded, this iron fence was so hard, could it be that this operation failed because of an iron fence?

Today's action was originally a qiēshun lì, the torrential rain was like a note, and even God seemed to be helping them, but here, they hit a wall.

Unbelieving, Enlina kept slashing at the iron fence with the Celestial Knife in her hand, but the one-handed knife turned into jagged teeth, and the fist-thick iron fence did not move, not even a single wound.

A group of people couldn't help but gasp, no wonder the people of Graham Castle didn't pay much attention to the sewers, it turned out that there was an iron general to guard the door, and ten thousand people couldn't open it.

Enlina leaned in front of the iron fence and took a closer look, this iron fence was poured directly on the surrounding pipes, and the entire sewer pipe formed a whole, to take it off, even more difficult than to destroy it, Enlina shook her head, very depressed.

Blatter also hurried over from behind, and he took out a battle axe from the ring, although it was not at the gold level, it was also a dark gold level weapon.

One-handed axe "Hurricane Axe", Excellence level, Durability: 147/147, Strength plus 19, Agility plus 16, Constitution plus 13.

The hurricane axe in Blatter's hand waved, although the resistance in the water was greater, and he could not exert the full power of this one-handed axe, but it still brought up a huge water whirlpool, and the sound of banging sounded continuously, and the iron fence finally trembled a little, and everyone's eyes lit up, haha, victory is in sight.

However, after slashing for a while, Blatter stopped in disappointment, and he shook his head helplessly at Enlina, and there was no trace of the iron fence in the magic light.

Everyone was a little desperate, this mere gate, is it still an epic or even legendary-level treasure? These are too extravagant, no wonder the underground drainage system map can be easily obtained, with this iron fence, Earl Graham is not afraid of someone sneaking in from here at all, if it is usual, if you want to destroy this fence, you must alarm the guards in the castle, this is simply the rhythm of death.

Fortunately, it was a dark and rainy night, and the sound of the thunderstorm drowned out the sound of their chopping, otherwise, they would have been destined to shed blood here at this moment.

Thinking of this, the twelve people all broke out in a cold sweat, and at the same time, they were deeply grateful.
