The underground tombs are very mysterious to the four clans, and even the four clans know very little about the underground tombs.

That's right, the city of the four clans was built on a huge ancient tomb, and the king of Fudo Ming didn't know why, nor did he know whose tomb it was, since he could remember, his elders told him: "Cub, there is a tomb under our house." ”

When Ling Huohuo first heard about this, he twitched the corners of his mouth, this is the rhythm of jumping on the grave, and the people of the four clans back then were really big-hearted.

However, the people of the four clans have opened up the passage to the underground tombs, but they mainly explored the part below the four cities, and later these places became the underground bases of the four clans, and there are passages to these tombs under each stone tower, and they can also reach other stone towers through the underground tombs and leave from other stone towers, which is why Ling Huohuo and Ling Tian told the existence of the underground passage.

However, except for the ancient tombs under the four clans, which are safe, the rest of the ancient tombs are not safe.

Although the four clans also explored back then, there were all kinds of monsters in the ancient tomb, and their strength was extremely strong, and they only explored a few passages that could lead to the other three cities, and the rest of the places were still a mystery.

According to his observations, the monsters in the ancient tomb have formed their own system, and because of that natural disaster, I don't know if there will be any changes in the ancient tomb, and whether the passage can be unblocked.

"Don't be in a hurry to go to the other three ancient cities, go and meet my eldest brother first, and you can take advantage of this time to recover." Ling Huohuo thought for a moment and said.

"Yes, master."

The Fudo Ming King turned into a golden light and entered Ling Huohuo's body.

The addition of the Fudo Ming King not only brought a sixth-order thug to Ling Huohuo, but also brought two things.

One is an exercise - "Fudo Ming King Mantra Fire", is the practice of the Fudo Ming King, the four clans have different attributes of the "Fudo Ming King Mantra", is one of the ancestral exercises of the four clans, combined together to form a set of "Fudo Ming King Array", but even if there is only a part of the fire attribute, the grade of this exercise is not low, if Ling Huo Huo cultivates this exercise, the power of the blood of the fire attribute will rise sharply, and you can better control your own fire power, the most important thing is that this exercise does not conflict with the "Sword Codex", You can practice at the same time.

The other is a full set of fire spells, the King of Fudo Ming is a fire family, and he naturally has a deep study of fire spells, and Ling Huohuo's control of his own fire power has only been used through absolute control, and there is no specific spell, and the power is only the power of the flame itself.

Even the move that can fly in the air through the explosion of flames is just some skills that Ling Huohuo has researched, yes, it is a skill, with Ling Huohuo's experience, it is still too early for him to create his own spell.

However, King Fudo Ming brought a lot of fire spells to Ling Huohuo, which just made up for Ling Huohuo's vacancy in this regard.

……

Ling Huohuo jumped out of the cave and entered the underground chamber, and began to follow the route given to him by the Fudo Ming King to make his way to one of the caves.

However, the moment Ling Huohuo entered the underground tomb, he felt a chill in his back, and when he turned around, he punched and hit something.

"Huh!" The thing that was hit made a sound like a baby crying.

Running the aura to his eyes, Ling Huohuo saw clearly what had just fallen to the ground after being hit by himself.

It is a green creature, not very large, only more than thirty centimeters, like a loaf of bread, with a large head, a large mouth, a mouth with hideous fangs, two pairs of thin wings on its back, a soft body, like a caterpillar, and three pairs of hideous thin legs on its abdomen, about five centimeters in length, covered with barbs.

At this moment, the creature was lying on the ground, its head half collapsed, and blue blood was bleeding, and it was impossible to survive.

Ling Huohuo felt a little disgusted and shook off the blood on his hand, and the flames appeared, burning all the disgusting things clean.

And at this time, the sound of "huohuo" sounded around Ling Huohuo, and Ling Huohuo felt that there were countless such insects staring at him in the dark, and he had been surrounded.

"It's a ghost worm!" The voice of the Fudo Ming King sounded in Ling Huohuo's head.

"Ghost bugs?"

"That's right, the cry is the same as the baby, it is one of the lowest creatures in the ancient tomb, the means of attack are large-mouth bites and hooked feet, it can glide for a short time, the fatal place is in the head, the strength is very weak, it generally exists as food for other creatures in the ancient tomb, there are many of them, and the fecundity is also very strong, and as long as you twist your head, the ghost worm can be eaten, Gaba crispy, chicken flavor."

I don't know if it's an illusion, Ling Huohuo seems to hear the immovable king swallow his saliva.

"In the past, when the clan fell into famine, they would catch ghost insects to feed their stomachs, and they could not satisfy their hunger and enhance their physique, do you want to try it?"

Ling Huohuo hurriedly shook his head, "Don't, don't, don't." ”

At this time, the sound of brushing sounded.

"The ghost worm is approaching." Ling Huohuo said.

"Ghost insects are very ferocious, they are not afraid of death, although their strength is very weak, but there are a lot of them, and it is also troublesome to be entangled."

"Then let's get through quickly!" Ling Huohuo smiled.

With a wave of his hand, his hands clenched into fists, and a flame ignited on his fist, looking at the ghost insects flying towards him, Ling Huohuo punched out, and the ghost insects were instantly killed, fell to the ground, and there was green smoke, Ling Huohuo smelled it, it was indeed very fragrant, and there was a smell of barbecue, phew, I won't eat it!

In this way, Ling Huohuo punched a monster, Ah No, it was a ghost worm, and he moved forward quickly.

"Please be careful, the tomb is not guarded by my people, so after a few years, the tomb is likely to be occupied by the monsters in the tomb again, and I don't know the specific situation."

"Good!"

Ling Huohuo continued to move forward.

There are still 800 meters to go to the target exit!

……

On the fire source city.

Ling Tian and the four of them were exploring this deserted Fire Source City.

Although most of the city has been destroyed, you can still see traces of the people who lived in the city, and you can feel the magnificence of the city.

"This city may well be a city where a civilization lost in history lived." Hu Han said with some excitement.

"What?" Yang Linger asked.

"I looked around and compared it with the contents of the database, the remnants of the frescoes and the text on the murals were not found in the database, and some of the murals in the city were mixed with a small amount of Sanskrit, but most of the words were unknown words, indicating that there must be a race living in the city that gave birth to a complete civilization." Hu Han explained.

"But where did that race go? We didn't even see a word of corpse, and the level of destruction in the city didn't look like an ordinary natural disaster. Wang Changfeng said with a frown.

While the three of them were discussing, Ling Tian shone his flashlight around, and his ears suddenly moved.

"Wait a minute, there's a situation!"

A dark shadow flashed through the ruins around the four of them.
