"Tomb?!" Chen Lin asked in surprise.

"Yes, the tomb, and it should be a big tomb, I found the beast grass just in the surrounding area, and this beast grass needs to have wild beasts, so there should be wild beasts in this tomb. ”

"Well, I know this, the reason why the beast mixed grass is called the beast mixed grass is because it absorbs the soul breath of the powerful demon beast and some other breaths of the demon beast. ”

"These breaths alone can produce such a wonderful thing as beast mixed grass, and you can imagine the strength of that demon beast. ”

Chen Lin nodded, "However, how can you get this beast mixed grass under such a powerful beast?"

Chen Lin looked at Lei Yu.

Lei Yu looked at Chen Lin and smiled, "No way, I'm lucky, it just so happens that the demon beast is not here, otherwise I wouldn't be able to get this beast mixed grass." ”

Lei Yu shrugged helplessly and smiled.

But it is true that Lei Yu's luck is very good, otherwise it would not have been possible to encounter this.

Chen Lin also shrugged his shoulders helplessly, and he had nothing to say about Lei Yu's luck.

"Alright, let's go in and see what makes you feel dangerous. ”

"Hmm. Let's go in. ”

Lei Yu's face became a little heavy at this time, and his whole body began to be vigilant, like a beast in danger.

Chen Lin's face was also heavy, and he was also vigilant.

Although he still has something to protect himself, there are no absolutes in everything.

Similarly, Chen Lin did not dare to guarantee that these things were also absolutely safe.

After all, this still needs a reaction time, once Chen Lin doesn't get the life-saving things out in this reaction time, Chen Lin and Lei Yu's lives will be seriously threatened.

Chen Lin didn't want to lose his soul before he got the treasure.

Chen Lin and Lei Yu slowly approached the entrance of the cave with many vines, carefully observing some things around them, so as not to encounter some dangers and have no time to deal with them.

"Well, it looks like there's no danger around here. Lei Yu whispered.

Chen Lin nodded, "But it's better to be careful." ”

"Uh-huh. ”

After getting closer to the entrance of the cave, Chen Lin couldn't help but be surprised, the hole that didn't look very big in the distance was now much bigger.

Lei Yu smiled lightly, and his original seriousness was a little less, but he was still vigilantly observing everything around him.

"It's the same as when I first started, I thought you wouldn't be like this if you were strong. ”

"Is it wrong to be surprised?" Chen Lin pursed his lips, "It's not that I'm afraid, isn't this normal?"

Lei Yu smiled secretly, and said seriously, "Well, it's quite normal." ”

......

As Chen Lin and the others walked cautiously, they soon came to the entrance of the cave.

The entrance of this cave constantly exudes a deep dead air.

Chen Lin couldn't help but feel a cold air coming to him when he saw it.

Lei Yu even felt like he had a cold aura all over his body, which directly invaded his heart.

He shuddered.

"It's really dark, it feels a lot darker than when I came. ”

"Looks like we're going to have to be careful, there's something going on inside. ”

"Well, it should be. Lei Yu nodded, "It seems that someone is coming again after I leave." ”

"Well, let's go, let's go inside. ”

Chen Lin cautiously walked into the entrance of the cave, and his spiritual sense was also released.

However, as soon as the spiritual sense was released, Chen Lin took the spiritual sense back.

"Well, what's going on here?" Chen Lin whispered to himself in confusion.

"yes, what's going on?" Lei Yu also looked around suspiciously.

The cave was pitch black, and only a little light from the entrance of the cave allowed Chen Lin to see some of the surrounding scenes.

The cave is very flat, as if it had been cut out with a knife.

However, all this was not the reason why Chen Lin and the others were surprised.

What really surprised Chen Lin and Lei Yu was what happened just now.

Just now, Chen Lin and Lei Yu both released their spiritual senses, but as soon as their spiritual senses were released, there was an inexplicable fluctuation that swallowed up their spiritual senses.

Chen Lin and Lei Yu hurriedly took back their spiritual sense.

"What the hell is going on, something has devoured our spiritual sense. Chen Lin was a little worried, and at the same time, his whole body fell into a kind of guard.

"I don't know, it didn't happen the last time I came in. Lei Yu replied softly, his voice extremely subtle, as if he was worried about the attention of the person who had devoured their spiritual sense.

"Looks like something has really changed. ”

Chen Lin also said softly, but his hands quickly knotted the mark at this time.

The body and mind are also integrated into this space.

And Lei Yu also seemed to understand Chen Lin's intentions, and he carefully paid attention to everything around them to ensure that Chen Lin was not affected by the outside world.

In this cave with only a little light, in the space, the slightest fluctuation is constantly transmitted.

This is exactly the fluctuation of the formation.

Obviously, Chen Lin wants to show off his skills. Now he was able to arrange the phantom array that he hadn't arranged for a long time.

In the previous battle between Chen Lin and Zhang Zhong, Chen Lin relied on this formation to make Zhang Zhong have no choice but to quickly send out his high-grade spirit weapon sword.

Now Chen Lin naturally wanted to get this formation out again and see what was going on around him.

The formation in the cave fluctuated faster and faster, and another wave followed.

The fluctuations were very manic, as if they were worried about something.

And with the strengthening of the formation fluctuations, this fluctuation also began to change.

They frantically came over quickly towards the place where Chen Lin and Lei Yu were.

Lei Yu also sensed this slight change.

Although he can't use his spiritual sense to perceive everything around him now, he is not an ordinary person, and his perception of the things around him is naturally stronger.

Especially the perception of danger.

Lei Yu now felt a strong sense of crisis rippling in his heart.

His mind instantly gathered, carefully feeling the changes around him.

"It's not good, this fluctuation, it seems that there is some powerful existence. Lei Yu took a sharp breath of cold air and called out in a low voice.

But Chen Lin, who was still arranging the formation, was awakened from that extremely mysterious state.

But Chen Lin was not as surprised as Lei Yu, he seemed to have expected it.

It's just that he still has a knot in his hand, and it's getting faster and faster, so fast that Lei Yu can't keep up.

"It's here. A giant axe appeared in Lei Yu's hand, and the giant axe that had been preparing to be infused with energy was filled by Lei Yu at this time, and it became huge.

He carried the great axe and slashed angrily forward.

But as if nothing had been cleaved, the great axe slashed directly into the cavernous ground, causing a hideous crack to appear here.

At this time, Chen Lin's hands stopped pinching.

A wave of formation fluctuations poured strongly into the cave.

"Now. Chen Lin snorted lightly.

The formation quickly became turbulent.

One by one, hideous insects appeared in front of them.

"Corpse worms. Lei Yu said in shock
