Under Zhang Yan's terrifying impact.

Not a single little wolf spirit could stop him for even a second.

In an instant, Zhang Yan had already killed the big wolf spirit.

However, this big wolf spirit did not retreat in the slightest, but directly launched an attack, rushing towards Zhang Yan.

The sharp minions were now under the firelight, revealing a terrifying cold light.

Zhang Yan was in danger, seized the opportunity, suddenly flashed, avoided the attack of the big wolf spirit, and hit it in the back with a heavy hammer, and a piercing sound of bone cracking spread throughout the cave.

I saw the big wolf spirit scream miserably, rolled to the side, and couldn't even stand up.

Obviously, the bones in his back were broken by Zhang Yanshen's blow.

Zhang Yan was about to go up to make up for a hammer and kill it, but the nearby wolf spirit was crazy, and kept rushing towards Zhang Yan, that situation was very terrifying, Zhang Yan had no choice but to take a few steps back and avoid the crazy little wolf spirit.

"Something is wrong, everyone be careful."

Aning warned again.

And the older Li He on the side also followed: "Normally, once the big wolf spirit is injured or killed, the little wolf spirit will inevitably collapse and flee in all directions, what's going on today?" Not only do these little wolf spirits not run, but they are so crazy. ”

"I can't care so much, just kill them all!"

Wang Ming shouted murderously.

When the words fell, the whole person's movements became more violent, and the spear in his hand seemed to turn into a streamer, constantly assassinating the little wolf spirit in front of him, no longer deliberately conserving his physical strength, and after a while, he killed a piece.

Fang Rin and the others glanced at each other and took the initiative to attack.

A quarter of an hour later, all the wolf spirits had been cleaned up.

The scene was bloody.

Fortunately, nothing abnormal seemed to have happened, and the big wolf spirit was also smashed by Zhang Yan with a shield, and was immediately stoned to death on the spot.

"Wang Ming, collect the teeth and claws of the big wolf spirit, and give up all the rest."

Zhang Feng ordered without hesitation.

In the face of Zhang Feng's order, Wang Ming did not hesitate at all, and immediately went up to clean up the battlefield.

The little wolf spirit also has sharp teeth, making it a good material for making arrowheads.

There are so many little wolf spirit corpses here, for ordinary people, this is a fortune, but for Zhang Feng, it is really nothing, but the teeth and claws of the big wolf spirit are scarce, and this can be left.

For fear that the smell of blood would attract other mutant beasts, after Wang Ming finished cleaning up the battlefield, everyone continued to go deep into the beast cave without delay.

Along the way, Aning is a leader.

From time to time, I took out a map in my hand, looked at it and looked at it, and compared it again and again.

Finally, after killing countless mutant beasts, the group finally came to a huge cave.

The location of this cave is very remote.

If it weren't for the map in Ah Ning's hand, it would be almost impossible for anyone to find this place.

And this is the destination of their group's trip.

I saw that in the huge cave, it was very empty, there was no monster, it seemed to be very safe, and in the center of the cave, there was a very simple stone door.

This is obviously a beast cave.

It is a place where human beings are extinct, and they may have gone hundreds of meters deep underground, how can there be a stone door at such a deep depth?

Who brought a stone door here.

"Is this the entrance to the fourth floor?"

Zhang Yan said with some excitement.

Zhang Feng shook his head, then nodded again.

"The last time I opened up the wasteland, there was a lucky guy, accidentally walked here, after seeing this door, although I don't know what it is, but I realized that it was a treasure, so I drew a map, and sold it to me at a high price, and this time, the purpose of our coming, is to study this door, I have a hunch, this door is very unusual, as for whether it is the entrance to the fourth floor, I don't know."

Zhang Feng explained directly.

Everyone suddenly realized.

It turns out that this is how the map used by Aning came about.

They all secretly praised the guy's good luck.

After understanding the cause and effect, everyone began to approach the stone gate and took a closer look.

This door stood in the middle of the cave, and there was nothing wrong with it, but everyone knew that this door was not simple, because it appeared here, which represented the biggest mistake.

This is obviously an artificial stone door, how can it appear under this hundreds of meters of ground?

Everyone was at a loss for a while.

Zhang Yan pushed it, but the stone door did not move.

Fang Rin, on the other hand, thought of the Thousand Heavy Ice Skeleton Tower.

Whether it was the Thousand Towers or the stone gate, Fang Rin always felt that it was not like a product of human beings, but inexplicably appeared on the earth.

And the way to open the Thousand Towers is to drip blood.

Fang Rin thought about it for a while, and finally decided to give it a try.

He bit his finger and smeared the blood on the stone gate, and soon, visible to the naked eye, the blood quickly merged into the stone gate, and the stone gate calmed down for a moment, and seemed to loosen a little.

Such a movement startled Zhang Feng and several others.

However, seeing that Fang Rin seemed to have found the trick to open the stone door, his eyes suddenly widened one by one, and his face showed excitement.

Fang Rin incentivized that the stone gate did not transmit the information, and it didn't seem to be able to be like the martial monument in the Thousand Ice Skeleton Building, but just now when the stone gate shook, Fang Rin understood very well that his way must have been used correctly.

He gently put his hand on the door and pushed it, but the stone door still didn't move, and he couldn't push it at all.

However, in the center of the stone gate, four grooves appeared.

"What does this seem to be putting in it?"

A-Ning said with a frown on the side.

Ah Huo shouted: "It won't be to release money!" Give money to open the door. ”

"Money is a fart, you know money money and money ...... in one day" Zhang Feng patted Ah Huo and scolded with a smile: "A stone door, what do you need money for?" Does it still have wisdom? ”

Zhang Feng's words reminded Fang Rin.

The stone gate may not need money, but it must need something to put into the grooves, otherwise how could it have four grooves on its own.

And the things placed should be very consistent with the size of these four grooves.

What does Shimen need?

Fang Rin frowned and pondered, suddenly, he thought of something, pulled the ugly little girl, took it out in her backpack, and found out four spirit crystals.

That's right, these four grooves, whether in size or shape, actually seemed to be exactly the same as the Spirit Crystal in his hand.

At this time, without Fang Rin opening his mouth, Zhang Feng and the others all knew what this stone gate needed.

Fang Rin picked one up and put it in the stone door.

Sure enough, it was very easy to put it in, the size was completely suitable, and when a spirit crystal was put on, the white light of the entire stone gate brightened up a little.

Everyone's eyes lit up.

It turned out that what was needed for this door was what Fang Rin was in his hands.

And Fang Rin didn't talk nonsense, and directly put all four spirit crystals on it.
