"Boom!"

A sound that shook the secret room came from Xu Fei's body, and I saw that the secret room was originally made of dirt compacted by Xu Fei, but after his body shook, the surface of his body suddenly erupted with a high temperature of more than 10 million degrees;

In an instant, the chamber was more than doubled, and the original soil layer was melted into a red, viscous, glassy substance, which continued to explode at a temperature of tens of thousands of degrees.

"Hoo ......"

Xu Fei woke up from his meditation with golden light in his eyes, he couldn't help but be startled when he saw this huge change in the place where he was settled, it was still tens of thousands of degrees of high temperature, he actually analyzed the temperature inside at a glance, his feet stepped on the high-temperature liquid like thin mud, but he didn't feel any temperature at all, which made him even more surprised.

"Ling'er, what's going on?" Xu Fei couldn't help but ask in shock.

Xu Ling'er is virtual body, she flew and looked around, smacked her tongue and smiled:

"Brother, I guess you have got a big benefit, just now the system condensed the golden pill for you, which little bell actually shot twice, you see that your golden pill and Danhuo are different from my records, but they are much more powerful than all the Jindan and Danhuo I know;

It's just that you can only use Jin Dan and Dan Huo to defend passively, and even alchemy and refining weapons can't work, I don't have the magic trick of using Jin Dan and Dan Huo to attack and refine things, it seems that that kind of flame attack ability can only be done to immortal fire, and I don't understand it very well, but my brother just remembers that this is a good thing, you see that the high temperature of tens of thousands of degrees has no effect on you at all. ”

Xu Fei squinted at his dantian. At this moment, the golden pill that should be golden in the knowledge of the system is now a silver-gray bead, and the danhuo on it is blazing white, but fortunately, that thing is now his own. He could see the flame clearly.

"Hey...... I don't understand, if it's really that thing, this Jin Dan and Danhuo are probably those legendary things, no matter him, look at the power of this flame, Danhuo out! ”

Xu Fei pinched the Danhuo Jue and shook his fingers, and the Danhuo that was originally in his body appeared on his fingers. This Danhuo was only less than the size of the flame when a lighter was lit, and the Danhuo had just appeared on his fingers from Xu Fei's body, and a ten-million-degree high temperature that had only appeared before suddenly erupted again.

"Close!"

As soon as Xu Fei felt this temperature, he put the flame back. But when he looked around again, the stone chamber had melted away again, turning into a large hole with a diameter of more than ten zhang.

"Paralyzed, it's so strong, it seems that it can't be taken out in the future. This is the Danhuo, if it becomes a baby fire, an immortal fire, or a holy fire. I rub ...... It didn't just come out of nowhere, and the earth burned down. Xu Fei looked at his fingers in shock.

The power just now made him really understand the power of his Danhuo, if it weren't for the fact that he was underground, he would have to take out a piece of Edelman metal to test how fast he would melt him.

10 million degrees, which is extremely difficult for future lasers to reach this temperature, of course, compared with the laboratory that only produces more than 10 billion billion degrees of absolute high temperature in only one quadrillion of a second, which is estimated to not even burn a speck of dust even if it hits the door of the human brain.

Xu Fei was still stunned, but Xu Ling'er smiled and said in front of Xu Fei:

"Brother, the effect of the system's level increase has been transmitted to your memory system. Now that you can fly with your edgeworth, your current pure physical strength has exceeded one hundred and fifty tons. The ability to run on the ground is also more than 200 meters per second, and with the Rapid Movement, you can reach twice the speed of sound on the ground, and your Edgeworth's speed is exactly twice the maximum speed of sound;

There is also a system that rewards you with a flying sword with a low-level immortal weapon, which can double your flight speed, that is, you can fly at four times the speed of sound at the fastest, but there is still no other flying sword technique for you to practice. ”

Xu Fei was still in the shock of Danhuo, and he should have sighed for Huifei, but he actually said calmly:

"Flying sword, take it out."

A small flying sword with only a little finger two or three millimeters wide appeared out of thin air and flew around Xu Fei, Xu Fei took out a drop of essence blood from the system inventory and bulleted it on the flying sword, only to hear the buzz of Xu Fei's special flying sword from the system and drill into Xu Fei's dantian.

This little flying sword is very arrogant as an immortal weapon, Xu Fei is a Jindan stage cultivator, it is a system that has no way to recognize Xu Fei as the master, he swayed around in Xu Fei's dantian, paused in front of the shadowless knife, and then rushed to the position of Jindan.

"Ding......

The position of Jin Dan has long been occupied by the small bell, and the flying sword was fixed in place by the sound of the bell before it rushed halfway, but the bell should know that the flying sword is Xu Fei's thing, and it just stopped the flying sword and re-restored the flying sword to its original state.

"Woo woo woo ......"

The arrogant flying sword continued to tremble, lowering the tip of the sword in submission, and then it swirled and flew around the dantian from afar.

"Cut, this little bell is also a bull fork, this will subdue the flying sword, I wipe the ......" Seeing that the flying sword went from arrogance to submission in less than a few seconds, Xu Fei couldn't help but curse secretly;

Even a weapon knows how to bully the soft and fear the hard, not to mention the people, remembering that little Japan has always been a dog for Lao Mei in later generations, not because hundreds of thousands of people were killed after eating two atomic bombs, if they continue to fight against the domineering Lao Mei, the little devils are afraid that all the territories will eat a few eggs and destroy their race.

This flying sword relies on innate induction to know that the little bell of the Dao Dao can't be provoked, and he can only put the tip of the sword on the outside even if he circles the dantian, fortunately, the level of the shadowless knife is too low, if he also has a tool spirit or something, it is estimated that he will laugh to death This flying sword that only dares to show off its might in front of him.

"Escape, out."

After two days and two nights of underground life, Xu Fei's figure came out of the ground in a flash, he put on his clothes and felt it, his mana used to be automatically linked to merit points, but just now he felt that the true yuan power in his body was consumed with the earth escape, but now the earth escape is dozens of times faster than before.

Xu Fei looked at the sky outside, it happened to be night when he went down, and when he came out, it was still full of stars.

"Ling'er, doesn't the mana after the Jindan period no longer depend on the number of merit points? Then how can I recover my true yuan power after it is consumed, didn't you say that I can't absorb the aura from the outside of my body? Xu Fei asked suspiciously.

This became a small master in the Jindan period when he was a cultivator at the low level, but Xu Fei couldn't absorb the aura of the outside world after being transformed by the Heavenly Dao, which was a big thing once it was consumed and there was no source of recovery. (To be continued......)
