The water is getting hotter and hotter.

When it was more than 300 meters away from the entrance of the cave, it was only a little warm, and after Ning Gang continued to sneak for more than 500 meters, after reaching the bottom of the cave, the lake here had begun to boil, and large bubbles were constantly gurgling and rolling.

And at the bottom of this boiling lake, there are a few palm-sized red crystals lying quietly. The red light that Ning Gang saw in the distance was emitted by them.

These crystals, shaped like ice ridges, have irregular hexagons, smooth edges like mirrors, and a dazzling red light, flashing one after another, particularly dazzling.

"What is this?"

Ning Gang's palm suddenly gushed out with a strong force, and a red crystal on the ground instantly passed through the lake and was adsorbed into Ning Gang's palm.

"It's hot!"

Ning Gang's physical attributes have long been able to withstand thousands of degrees of high temperatures, but with this crystal in his hand, Ning Gang can still feel the slightest bit hot.

"How can there be such a thing in this lake?"

"Master, these things are called Volcanic Crystals."

Kubridge's voice suddenly sounded in Ning Gang's ears, "They are all the essence of the fire element. ”

"Volcanic crystals, the essence of the fire elemental?" It was the first time Ning Gang had heard of such a thing.

"There are three types of volcanoes in the universe."

"An active volcano."

"Extinct volcanoes."

"There is another type, which is the volcano, which is not very common in the universe." Kubridge said.

"Volcano?"

Ning Gang muttered to himself, he knew about active volcanoes and extinct volcanoes, but this volcano was something.

"A volcano is an active volcano that is half dead and half alive and will never erupt."

"Say it's dead, but there's still a flow of fire elements in it, and it's still alive on the surface."

"It's still alive, but it's always like it's resting, and it never erupts."

Kubridge explains, "These fire elements, which don't flow to form magma, do coalesce together to form this volcanic crystal. ”

"Moreover, it will be difficult to form without a million years."

Ning Gang was a little clear, this breath volcano was actually an active volcano that was sleeping forever, but it could not erupt magma, but instead condensed inside, forming this kind of volcanic crystal.

"This volcanic crystal, which contains a large amount of fire essence, is the crystallization of fire."

"It's a pity that the scale of this volcano at the bottom of the lake is too small, with a diameter of only more than 100 meters, and the energy it contains is not much, only forming these palm-sized volcanic crystals."

"Their energy is only similar to the Tianshan Snow Lotus that the owner just obtained, and they are not real treasures."

"The real sense of the volcano in the universe is generally millions of miles in diameter, or even larger, hundreds of millions. The volcanic crystals they form are the things that make up for it. ”

"My original owner and I once encountered a large volcano with a diameter of nearly 500 million miles in the universe, and the volcanic crystals it bred were extremely large and the energy was also very strong."

"At that time, more than 30,000 cells of the original owner had matured. Moreover, at that time, the owner's cells had matured hundreds of thousands. ”

Kubridge smacked his lips, and he missed that opportunity very much.

"So much."

Ning Gang was also shocked, he knew that the more the cells went to the back, the more difficult it was to mature, and the energy required increased exponentially. More than 30,000 cells have matured at once, and the energy contained in the volcanic crystal will be huge.

However, Ning Gang then shook his head and waved this deep envy out of his mind.

Ning Gang knew that this kind of thing could only rely on his own luck, and he couldn't force it at all.

"It's already a great blessing for me to be able to meet these volcanic crystals today."

"People's hearts, can't be too greedy."

"One"

"Two"

"Three" ......

"Seven in total."

"I just don't know how many cells these seven volcanic crystals can make me mature."

Then, the palm light shone, and when the first fire crystal turned into nothingness in Ning Gang's hand, Ning Gang let out a wry smile, "One hundred and fifty-six cells." ”

"Kubridge said that the energy contained in these volcanic crystals is comparable to that of the Tianshan Snow Lotus that he just obtained, but he didn't expect that only one hundred and fifty-six cells had matured."

"At that time, the first snow lotus had more than 300 mature cells, and the second had more than 200 cells. Now this volcanic crystal, that's all. ”

"I only hope that this opera volcanic crystal can make the number of mature cells reach more than five hundred, so that they can get out of this hole."

Ning Gang's current highest combat power is 6726, but the snow toad at the entrance of the cave has 8652. Only when at least more than 500 cells have matured and more than 1,500 combat power has been added, can Ning Gang be sure to walk out of this cave and even kill this insect beast!

But now it seems that there is little hope.

The second, one hundred and twenty-three.

The third, eighty-two.

Fourth, fifty-four.

Fifth, twenty-eight.

Sixth, fifteen.

Seventh, eighth.

Four hundred and sixty-six in total.

"Not enough!"

Ning Gang frowned deeply, "Four hundred and sixty-six, representing 1398 combat strength, that is to say, his current combat strength is only 8124, which is 528 points worse than that snow toad." ”

"With these 528 points of combat power, you will completely take your own life."

"The chance of escaping by yourself is less than one percent."

Just when Ning Gang was muttering to himself, a little anxious, Kubridge's voice rang out, "Master, don't worry, you can completely kill the insect beast at the entrance of the cave, but it will take a little longer." ”

"Huh?"

Ning Gang's eyes lit up, "What do you say?" ”

"Master, there are two conditions for the formation of this volcanic crystal, one is the volcano, and the other is the vein, without the mine, it is completely impossible to form a crystal."

"I've just scanned this volcano, and the mountains inside are full of ore."

"It can be said that the entire volcano is a vein."

"A most primitive, tin vein."

Kubridge explained, "If the master wants to get out of this cave, he just has to swallow up the whole vein of tin. ”

"Although the energy contained in each side of ore is not much, it is better than the quantity."

"I just estimated that the energy contained in this tin vein can allow the owner to mature another two or three hundred cells. At that time, the master's combat effectiveness will never be worse than the insects and beasts outside. ”

Ning Gang's eyes lit up, "Two or three hundred cells, that means at least six hundred combat power, and I can definitely kill this beast outside!" ”

"My own devouring and star-devouring technique, cultivated to the extreme, is known as even the stars can be devoured, and everything can be turned into energy. This tin vein is certainly possible. ”

"Master, the ore vein is no better than the 'Battle Fall', the 'War Fall' is the corpse of the universe powerhouse, and all the energy can be directly absorbed."

"But this vein contains too many impurities, and not all of them can be absorbed. Therefore, the master uses the Devouring Star Devouring Technique to refine and absorb, and it will take a long time. ”

"According to my estimates, it will take five or six months for the master to devour the entire ore vein, that is, the entire volcano."

"Five or six months, that is, half a year, is not much."

Ning Gang said in his heart, "This time, in the original student days, can only increase the combat effectiveness by ten points at most. Now that he is trapped here by that insect beast, at least, his combat strength can improve by leaps and bounds. ”

"Can I still contact my parents in this place?" Ning Gang asked. What he is most worried about now is that he is afraid that his family will not be able to contact him, so he will start to guess.

"Yes." Kubridge replied.

"That's good, now, there's nothing to worry about." Ning Gang breathed a sigh of relief, all this was more important than anything else......

"Zhu Haoer, I didn't expect that you would not die in that situation, and you would be able to come back from the Tianshan Mountains alive, it's really fateful."

Keihoku City.

In a simple wooden house, a middle-aged strong man in his forties looked at Zhu Haoer, who was lying on the ground and had his left arm cut off, with a cold face.

"And you two, what are you doing with him?"

"I really think that my life is hard, and those beasts in the Tianshan Mountains can't help you, so I think that our Tianhu mercenary group can't help you?"

The direction that the middle-aged man was looking at was Meng Qian and Bo Jin, who were already seriously injured and almost unconscious.

This middle-aged strong man, dressed in black-level legendary equipment, is just a big knife and ring in his hand, but it exudes a red light, although it is a little weak, but it is a genuine red-level combat knife.

There were still a few people standing behind the middle-aged man, with unified black-level boutique equipment, like a strong man, sneering at the three people on the ground.

"Whew!"

Zhu Haoer spat a mouthful of blood on the ground, ignoring the severed left arm, glaring at the middle-aged man angrily, his voice was resentful, "Fu Dong's dog is really the same as a beast like you." ”

"It's not Fu Dong's dog offal, how can I deceive you, who made you good brothers?"

The middle-aged man laughed, "If it weren't for the fact that I couldn't contact Fu Dong and found out that he had been chopped up by you, I didn't know that you had already returned." ”

"Your Black Hawk mercenary group, twenty-eight people, twenty-five brothers died, I don't know, what face do you have to come back."

"Haven't you mercenary groups always claimed to live and die together? Since they are all dead, why don't you go with those brothers to die together? The middle-aged man's face was full of mockery.

"We don't die, we are here to take the life of your dog, to give my brothers a funeral!" Zhu Haoer gritted his teeth, looked at the middle-aged man in front of him, and said word by word.

"Haha, you're taking my life?"

The middle-aged man laughed, as if he heard the best joke in the world, "Your combat power is 350, but my highest combat power is more than 420, a full seventy points of combat power gap, I want to see how you Zhu Haoer took my life." ”

Zhu Haoer's face changed, he looked at Meng Qian and Bo Jin who were lying on the ground, and made some kind of decision in his heart in an instant.

"Brother Ning Gang, I'm sorry, what I promised you, I Zhu Haoer can't do it!"

"This bottle of high-grade combat power elixir can't be handed over to your sister, for the sake of Meng Qian and Bo Jin, as well as the lives of my brothers, I will drink it first!"

"When the time comes, you want to kill or scrape, whatever you want!"

A bottle of blood-red elixir instantly appeared in Zhu Haoer's remaining right palm, and without the slightest hesitation, he crushed the cap of the bottle and poured it into his mouth.

A moment later, the sword shone brightly, staining the wooden house with blood.
