Van Lin Bowei said: "It was this senior who saved you, he said that the reason why you did not die is because the fire power in your body is maintaining your life, but this fire power is now very weak, ethereal, if you can comprehend the firepower, condense the fire power in your body, and practice solidly, then your life can be saved, otherwise, after five days, the fire power in your body will disappear, and you will die." ”

"I never felt a fire in my body." Zhenqiang looked at himself and said.

"Fire, not fire." The mysterious old man said again with one hand behind his back and one hand on his beard.

Van Lin Bowei said again: "It's really strong, you don't feel it, it's because the fire is too weak, but we can see that your eyes often glow red, including now, your eyes are shining red again." ”

Ciri said at this time, "Stupid man, your eyes are really bright red again, and I have seen them before. ”

"Ciri, I used to have red eyes, too?" Zhenqiang asked.

"Well, I remember the first time your eyes lit up with red light, you knocked Alia out with one punch, at that time, you had just reached the state of potential strength, and he was in the advanced state of extreme strength, and the difference in strength was so big, and you later blocked his waterfall and electric fire, at that time, your eyes were lit up with red light." Ciri said.

After hearing this, Zhenqiang was shocked for a moment, and said: "Even if I have firepower in my body, I can't wait for five days, I have to go to save Esmerada now," After speaking, he was about to walk out with the Eternal Fire Knife.

"Everything is planned for the long term, not in a hurry, although it is a race against time, but it is necessary to be fully prepared in advance, and long-term planning is a stable move. At this time, the mysterious old man said.

"Four or five days have passed, if there is a disaster, it has already happened, it is too late to go, if there is no disaster, it will be safe now, and there is no great benefit to go, within five days, if you comprehend the firepower, then there will be enough time for the future, let you do it, if you do not comprehend the firepower, then these five days, let you be anxious, once the five days pass, you will definitely die." The mysterious old man said again: "It's better to comprehend the firepower now, and if you practice it early, you will be able to recover sooner, and the days are running out, only five days." ”

Zhen Qiang was stunned for a moment, stopped, looked back at the mysterious old man and said: "Senior, I really don't know if I have firepower in my body, the flames I emit are all the power of this eternal firepower knife, even if there is, how should I feel it, how to practice firepower solidly." ”

The mysterious old man said: "Two thousand years ago, the Eternal Fire Knife was the weapon of the Flame Extinguisher, with your current ability, you didn't even exert one-ten-thousandth of the power of the Eternal Fire Knife, do you know how to use it?" ”

One ten-thousandth of the power was not exerted, and it was really strong and shocked.

As soon as the mysterious old man stretched out his hand, he saw a 'whew', and the eternal firepower knife in Zhenqiang's hand suddenly erupted with blazing sharp flames, as if it had a tangible substance, and the heat wave in the room suddenly rolled, like a flame.

Zhen Qiang suddenly felt that his right hand was hot, and his palm was as if it was about to be melted, and he let go of his hand violently, and at the same time he was shocked in his heart, at this time, the flames sprayed by the Eternal Fire Knife were dozens of times stronger than when he burned the black rune fire of Sidum, and it turned out that the flame when he burned the black rune fire was not the greatest power of the Eternal Fire Knife.

After the Eternal Fire Knife was released, it did not fall to the ground, but it was suspended out of thin air, and then flew into the hands of the mysterious old man.

The mysterious old man did not hold the hilt of the knife with his hand, but directly pinched the blade of the knife that sprayed the scorching sharp flames with his hands, allowing the hot flames to burn his palm.

And his palm had no effect in the slightest, and the blazing flames from the Eternal Fire Knife didn't seem to hurt the old man's hand at all.

Zhenqiang looked at the mysterious old man in surprise, ordinary, ordinary, just like an ordinary old man, without a trace of excess breath released, but invisibly it gave people a feeling of strong power like an abyss, endless, with no end in sight, although it did not exude a powerful aura of power, but it was more terrifying than those who exuded a powerful aura.

Zhenqiang's whole person seemed to be surrounded by his power, in the abyss of his endless power, and he couldn't move at all for a while.

The mysterious old man looked at the eternal fire knife in his hand that sprayed a scorching sharp flame and said: "This knife is called the eternal fire 'power' knife, not the eternal fire 'flame' knife, firepower, not flame, flame is just an external manifestation, its essence is firepower, a hundred percent flame, in order to produce one point of firepower, that is, one point of firepower, can produce a hundred points of flame, firepower, a hundred times stronger than the flame." ”

"The temperature in our human body is very high, and the high can melt steel, which is life energy, and its essence is life fire, which is often called the fire of life." The mysterious old man said: "Each of us has life fire in our body, and if a person dies, the life fire will disappear, so the temperature of the human body will decrease,"

"There is life fire in the human body, but there is another kind of fire in the world - energy firepower!" The mysterious old man said.

"Energy firepower ......." I was really stunned.

"Energy firepower is hundreds of millions of times more powerful than life firepower, the earth is energy firepower, the sun is energy firepower, the fire power in your body is energy firepower, when your life fire disappears, that trace of energy firepower will automatically maintain your life firepower, keep your life,"

The mysterious old man said: "What power in this world is eternal, only firepower is eternal, this is the eternal firepower knife." ”

Zhenqiang was shocked in his heart, and suddenly had a feeling, vaguely as if he had spied a trace, but he didn't know what to wake up to.

The mysterious old man looked at Zhenqiang's expression change, nodded slightly, and finally said: "The power you want to exert is not fire, but firepower, life firepower and energy firepower, understand?" ”

Zhenqiang's eyes lit up, a flash of inspiration flashed, as if he had woken up, and said, "I understand." ”

"Yes." The mysterious old man nodded and said: "You can comprehend the truth of firepower so quickly, very good, 50 years ago, there was a minotaur who also got the eternal firepower knife, I was going to teach him how to use it, but I found that he was too murderous, so I dispelled this idea, I see that you have a calm heart, no desire to kill, although you are often angry for helping others, but there are no evil thoughts." The Eternal Fire Knife contains a torrent of firepower, and all I have exerted is a trace of power generated by him, like a wave raised by the sea, a splash of foam. Although I am not proficient in firepower, and firepower is not my main ability, it is still okay for you to use my firepower to this extent, are you willing to follow me to learn the method of firepower cultivation. ”

"I do, Senpai." Zhenqiang hurriedly said, he had already felt the power of this mysterious old man, incomparable, supreme.
