Chapter 519: The Bottom of the Trench

It's no wonder that Wu Meng was so surprised, just now when he saw the tens of thousands of green needles rushing towards Haitian, he even thought that Haitian was finished, who would have thought that Haitian would survive?

"Whew, it really scared me, and to be honest, I didn't expect it myself. At this moment, the undercurrent has receded, and the countless impactful green needles have gradually dissipated, but the gap is not as big as just now. Haitian relied on the red light mask in front of him, and the flute opened the surrounding green needles, artificially creating a huge gap, "Okay, come down quickly." ”

I have to say that Haitian's hand surprised Wu Meng again, people avoided these green needles, but Haitian knocked them away.

"What are you doing here, come down quickly!" Seeing Wu Meng's astonishment, Haitian hurriedly shouted.

At this time, Wu Meng came back to his senses and hurriedly swam towards Lu, but the pressure was getting bigger and bigger, so he had to use all his strength. Fortunately, without the hindrance of the green needle, it was easier for him to think about it.

Passing through this layer of green needles, Wu Meng hurriedly swam to Haitian's side and asked, "Brother Haitian, what is the red ball of light on the top of your head? It is so powerful that you are not even afraid of the green needles? I think it is at least an artifact-level treasure, right?"

"Almost, alright, let's not waste time, let's go down quickly. Haitian smiled, didn't explain, and swam directly down.

Seeing Haitian like this, Wu Meng knew that Haitian didn't want to say it, he was also interested and didn't ask again, and swam out of Haitian after him. It's just that he kept thinking in his heart, what kind of artifact is this red ball of light? Wouldn't it be another high-grade artifact?

After passing through the green needle layer, Haitian put away the fire spirit ball, and his sword sense noticed that there was no such a large area of green needle layer below, it was just some scattered green needles, as long as he was careful, there was no problem in dodging it.

It was only soon that Haitian realized that something seemed to appear under the trench, which completely blocked his sword sense. You must know that Lu Dao is now in the entire Nether Realm, and there is basically nothing that can stop his sword sense, but there is one here, why is Haitian not curious?

Just as Haitian was about to dive quickly, Wu Meng, who was following Haitian, suddenly exclaimed: "Brother Haitian, look here!"

"Here?" Hearing Wu Meng's exclamation, Haitian immediately looked over, but he soon found that Wu Meng was pointing to a very long and thick cyan stone pillar! Haitian had noticed it before, this stone pillar was very long, leading directly to the bottom of the trench, "What's wrong?"

"Aren't you a master of refining? Don't you know? This is a slime stone! Material for refining artifacts!" Wu Meng said disdainfully.

"What?materials for refining artifacts?" Haitian was suddenly surprised, he was a refining master, but he didn't even know how to refine a heaven-level high-level sword weapon at all, let alone an artifact. At present, he is completely blind to the artifact, and he doesn't understand it at all, and he has never seen the materials for refining the artifact.

Wu Meng looked at Haitian with disdain again: "Of course, I have seen it in the hands of the refining master of the God Realm, although this slimestone is not the most precious among the materials for refining artifacts, it is also extremely rare, I heard that if the level is high, it is possible to refine high-grade artifacts!"

"I'm X, then this is really a good thing, I have to get some of it quickly!" Haitian didn't think about it, and immediately took out his heaven-level sword weapon, wanting to dig something out of it. It's just that before he could dig it out, there was already a gap in the Heavenly Rank Sword Weapon.

Wu Meng looked at Haitian with a smile: "I said Brother Haitian, this is a material that can refine a high-grade artifact, what's the use of you taking a heaven-level sword weapon? ”

"Oh, yes, thanks for the reminder!" Haitian forgot about his hurry, and he hurriedly took out the artifact he had seized earlier from the storage ring, and chopped up the huge stone pillar with great force.

Soon, Haitian dug up a lot of slime, although it was not too big, but the amount was definitely enough for him. Besides, if there is a shortage in the future, he can come again.

"Brother Haitian, I think this trench is definitely not ordinary, we need to be careful. Wu Meng said with a frown.

Needless to say, Haitian has already seen that this trench is unusual. Just imagine, what trench will have so many green needles that even the masters of the God Realm are afraid of, and what trench will have materials for refining artifacts on a stone pillar? ,

And Haitian still has reason to believe that the material under this stone pillar is probably even better than this slime!

As soon as he thought of this, Haitian couldn't wait to swim down. I have to say that this Maria Trench is really deep enough, Haitian and Wu Meng have been diving for several hours, and they still haven't seen the protective shield at the bottom.

After a long dive, Haitian felt that he was getting closer and closer to the protective shield, and the color of the slaprite on the stone pillar next to him was getting better and better, almost to the point that there was no trace of impurities.

To Haitian's relief, not only did the number of green needles in the trench not increase, but gradually decreased, probably only in the central area there will be more green needles, but in the upper and lower areas there are no green needles.

After diving for a while, the surrounding green needles had completely disappeared, and Haitian and Wu Meng were gradually able to see the bright light coming from below.

Wu Meng shouted happily: "Brother Haitian, we are finally going to dive to the bottom." Look, there's a hood there!"

"Well, I saw it!" Haitian nodded his head, and his body immediately went downstream.

Soon, he and Wu Meng had already reached the top of the hood, and they could even see the scene inside through the hood. Inside the hood was not the Flood beast they had imagined, but a tall building stood silently there.

"Brother Wu, you see that there is no water in this cover. Haitian looked at the inside of the hood that was completely different from the outside, there was no fluctuation of flowing water, and couldn't help but ask suspiciously.

Hearing Haitian's words, Wu Meng immediately looked down, not to mention, there was really no water in it. Wu Meng's answer made Haitian's brows furrow even tighter, to know how much water was hoarded in this trench, this pressure was terrifying. However, this cover was able to completely resist it, and a palace was built inside, which can be imagined how terrifying the strength of this builder was.

"Hey, Brother Haitian, look, is that the black key you're looking for?" Just as Haitian was thinking about how to enter this cover, suddenly Wu Meng next to him screamed.

"What?" Hearing this, Haitian immediately lowered his head and looked in the direction Wu Meng pointed, not to mention, on the ground next to the palace, there was a black key lying quietly, this style and the energy in it were exactly the same as the past few handfuls!

"Yes, yes, that's the key!" Haitian exclaimed excitedly, after looking for so long and spending so much effort, he finally found the last key, and with this key, it means that he can enter the mansion of the Nine Heavens Sword God!

But then the question arises, how can he get in? This cover is obviously waterproof, and I am afraid that it also serves as a defensive barrier to a certain extent, and it may be difficult for outsiders to get in.

"Brother Haitian, how do you say we should go in now, do you want to break it by force?" Wu Meng looked at Haitian and asked.

"Force?" Haitian shook his head lightly, "I'm afraid it's not good, this cover can withstand such a large water pressure, I'm afraid it's not something we can break, it's better to think of other ways." ”

"That's right, but how do you get in? There's not even a gate, and I don't know how the black key gets in. Wu Meng pursed his lips, "I don't know which great god built this palace here." ”

Haitian, who had been bowing his head and groaning, heard Wu Meng's words, and suddenly raised his head and said, "Wait, what did you just say?"

"What did you say? I didn't say anything, I just said that I don't know which great god built the palace here. Wu Meng scratched his head in confusion, "Brother Haitian, what do you want to ask?"

It's just that Haitian hurriedly shook his head: "No, it's not this sentence, it's the previous sentence." ”

"Again, it seems to be 'I really don't know how the black key got in?'" Wu Meng looked at Haitian in confusion.

"Yes, that's it. Haitian exclaimed excitedly, "Since the black key can enter, why can't we enter? Maybe this cover is just waterproof." ”

"Wouldn't it?" Wu Meng opened his mouth in surprise.

Haitian nodded: "It's very possible, maybe this builder just took advantage of our psychology, so that we can see that this cover can withstand even such a strong water pressure, and naturally it can withstand everything." It's just that he didn't expect that a small black key would fall into it. If you don't believe us, let's try!",

As he spoke, Haitian stopped talking nonsense and stretched out his hand directly towards the cover. Although he said that, his heart was still very nervous, what if he guessed wrong?

His eyes widened, and his right hand slowly approached the hood, which was less than five centimeters away. Haitian put his right hand under it again, and it was already attached to the cover, and he could even feel the cold feeling on the cover.

Extending down again, his right hand penetrated without any suspense, as if there was no force to block it at all.

This was the great joy that Wu Meng next to him looked at: "I have passed through!

"Let's go, let's go down quickly!" Haitian was overjoyed, and hurriedly put the whole person through, but he didn't expect that this layer of cover was really what he imagined, it was just waterproof, and there was no defense at all.

With the excitement in their hearts, Haitian and Wu Meng came in directly from the outside of the hood and fell directly to the ground. Haitian picked up the black key, and finally put down a big stone hanging in his heart.

The keys to open the Nine Heavens Sword God's Mansion have finally been gathered, but unfortunately there are still six more that are no longer here.

Just when Haitian sighed about this, Wu Meng next to him suddenly exclaimed: "Brother Haitian, come over and take a look!"

Hearing Wu Meng's exclamation, Haitian immediately raised his head and found that Wu Meng had actually walked to the gate of the huge palace. Haitian immediately went up, but when he saw the plaque at the entrance of the palace, he also exclaimed: "What!
