When Tang An saw that the roots at his feet were already mixed with the dark red soil and pulsing slightly, he knew that there was something wrong with the roots.

In other words, the surrounding trees may not be just simple plants.

They are ‘living’.

The hidden scene of this swamp mill is obviously different from the previous underground manor.

That manor is a little less open, after all, the scene is limited.

But here, the openness is very high, and in other words, it has a lot of freedom.

Tang An now has several options.

One is to fight the headless knight directly, and even find a way to kill him.

Also, they just ignore it and run away. In addition to these two, they can also explore other things.

For example, what Green and others said before, or to figure out what these strange tree roots are under their feet.

Different choices may be different.

Moreover, Tang An could see clearly that the fog around him was emitted by the roots of these underground trees.

Tang An has a choice.

There is no need to fight head-on with the headless knight.

Escape is not within Tang An's option, and he doesn't know where the dark altar is. Therefore, the safest way to explore now is the roots of the tree under his feet.

Holding the small bottle of holy water in his hand, Tang An scattered a little more on the ground.

A sting.

The roots of the tree that were soaked by the holy water directly emitted white smoke and then retracted frantically.

After trying several times, Tang An found that in some places, the roots of the tree will shrink back, while in some places, they will not.

The retracted tree roots will eventually retreat in one direction. Tang An felt that he had found the key.

Walking in this direction, Tang An soon saw a dead tree.

The dead tree is very big, four or five meters high, surrounded by at least four people. What's strange is that if it were such a big dead tree, Tang An would not have noticed it at all before.

Those strange tree roots extend from the roots of this dead tree. A brief look at them can cover hundreds of meters around them.

At the root of the dead tree, there was another huge gap at this moment, just like a person's belly being thrown away. It was obviously a tree, but inside it was a bit like the internal organs of some kind of creature.

The gap is downward, like a big hole.

Tang An suddenly had an idea at this time.

Could that headless knight come out of this?

Very likely.

Tang An looked down, hesitated for a moment, and then recalled three ghosts.

With the ghost dictionary, recalling the three ghosts was only a matter of a moment, but Vivian obviously couldn't come back at once.

Tang An knew that Vivian was extremely strong, especially with her keenness, so she would not have any trouble alone.

Thinking of this, Tang An directly drilled downward along the gap in the tree hole.

The following is more spacious than Tang An imagined.

This is a very large underground cave, and the tree cave is just an entrance.

While coming down, Tang An also received a prompt that his exploration degree was increased, and it has reached 16%.

Sure enough, exploring this place is a wise choice.

Exploration says it all.

It is not completely light-dead here, it can only be said to be dim, but with Tang An's eyesight, it is still possible to see clearly within a range of at least ten meters.

I looked around and saw countless tree roots hanging down from the top of my head, looking a little weird, and there was a downward tree hole not far ahead.

After walking over and taking a look, Tang An saw many horse hoof prints from the tree hole.

"Was that headless knight been under here before?"

A thought popped up in Tang An's mind.

Keep moving forward, and the space suddenly becomes larger.

Tang An saw an altar near the rock wall in front of him.

The reason why you can see this is an altar at a glance is that it has very obvious characteristics, such as the weird totems outlined and placed with blood and fur of some animals, and various mysterious symbols.

When you look closer, you can see that the altar is not small, with a skull in the middle.

The skull was just there. After Tang An approached, several thick candles around him that had become strange and suddenly lit them by themselves.

I believe that even if these candles continue to burn, they can still burn for a long time.

With the light source, the feeling is even more weird and terrifying than before.

The small flame of the candle brought light, but also brought shadows. As the candlelight swings and jumps, the shadows around seemed to be alive, twisting and deforming.

Those who are timid here will definitely not last long and will be frightened and fled in panic.

Tang An is not afraid.

He found that his nerves were constantly being tempered, as thick as steel bars, but he was not afraid anyway.

Maybe because he had been frightened several times before, he found that as long as he had a big fist, no matter what strange things you had, he would end up being finished.

Having strength is the bottom line.

It is truth at all times.

Tang An felt that this place should be what Green and the others called the dark altar.

Unexpectedly, I discovered this place by chance.

After looking at the exploration level, it was 19%.

In other words, this altar is indeed a more important thing in this scene.

At this moment, the three ghosts noticed something and gave Tang An a reminder.

The next moment, a tall figure came over from the other side.

If you look closely, you will find that Agurus, the sleepless person.

"really!"

Tang An had known for a long time that this guy must have been prepared for summoning the headless knight. Since he was prepared, he would have thought of a way out after causing trouble.

This dark altar is so important that the sleepless Agurus is likely to hide here.

But Tang An felt that if he was plotted against by others, he would definitely escape if he had the chance and would not stay here.

Under the dark candlelight, the sleepless Agurus' expression was extremely hideous and terrifying.

He obviously wanted to do it.

But the next moment, he stopped.

Because he saw three ghosts appearing around Tang An.

The female ghost and the ghost swordsman, Agurus, who is sleepless, does not recognize it, but the Singer of Doom belongs to a very famous "strange legend" in this world, so after seeing the black doom, Agurus's face suddenly looked very ugly.

Tang An smiled.

This guy is awesome, but he is even more powerful.

I'm not afraid of the headless knight, what kind of waves can you, Agurus, make?

"Do it!" Tang An had the advantage, afraid that he would be a bird, so he immediately ordered the ghost to attack. Agurus, the sleepless man opposite, immediately said: "Wait a minute."

Tang An called back the ghost and wanted to hear what the other party was going to say.

"I've misunderstood. You are a strong man, even stronger than that guy Green. Let's join forces. There are headless knights outside. Green and the others are not opponents. They may have been killed. The dark altar is about to open. I will give you five chances of sacrifice three times, and I will only use them twice."
