Don't look at Yang Yifan's relaxed demeanor now, in fact, he doesn't have any bottom in his heart, although the system is in hand, but I want to have it in the world, it is still a little difficult, if the merit value is enough, you can also buy magic weapons in the system's store to destroy this ugly thing, but unfortunately the balance of merit value is now zero, and the last 10 merit points are also used to buy "Mai God Arithmetic" and give it to Lin Yiyun.

At this time, you must not be cowardly, show a little timidity, and this frog demon king will immediately notice.

Yang Yifan secretly cheered himself up.

A man can lose strength for a while, but the force must be high.

Back then, Zhuge Wolong, there was no general around him, but he put forward an empty city plan, and scared Sima Yi away, not because he was forced high enough.

"Little frog, do you sing or not, if you don't sing, I'll roast you and eat it later. Speaking of which, I haven't eaten this frog meat yet, so I don't know what it tastes like?"

Although Yang Yifan said lightly, Su Qinglan behind him clearly saw that his back was already soaked by the moonlight, Su Qinglan was a smart woman, and she immediately knew that he was going to walk over to him in the face of the pressure of the frog demon king.

Yang Yifan shook his hand at her and signaled her not to move, but because he didn't have the sound transmission technology of Ghost Yuanzi, he would have asked her to run away secretly.

The frog demon king saw that he looked confident, and he was immediately frightened by him, but he was reluctant to leave like this, he came here, and he had to try his strength.

Yang Yifan discussed with the system in his heart: System, can you give me a credit account first, and give me the magic weapon that can deal with the frog demon king on credit, and then I will return it to you when I earn enough merit points.

System: No, there are rules, and you can't break the rules.

Yang Yifan was unhappy for a while: If you don't give it to me on credit, wait until I kill it, then your system will be abolished.

System: What are you kidding, you're not the only one on Earth, and if you die, I can find a host again.

Yang Yifan secretly swore: When my strength is enough, I will trample your broken system under my feet and rub it on the ground.

The frog demon king thundered him and rained a little, and he didn't move for a long time, he was already suspicious, and slowly leaned over like him.

Yang Yifan knew that this empty city plan had failed, so he grabbed the Xuantie Sword with his backhand and waited for it.

The Frog Demon King's footsteps slowly accelerated, and he was already less than three meters away from Yang Yifan.

Yang Yifan hurriedly swung the Xuantie Sword, and with the dance of the evil sword technique, one spirit rune floated in front of him.

The frog demon king faced more and more spirit runes, but he seemed to be scared at all, opened his mouth and sprayed, and in an instant, a gust of wind hung up, flying sand and stones, blowing one by one spirit runes, floating in all directions.

Yang Yifan swung his sword to block, and only then did he barely stand firm in the wind.

After this confrontation, the frog demon king roughly understood his strength, and roared angrily: "It turns out that you have this ability, and you almost deceived this king!"

Yang Yifan grinned and said, "Little frog, who is your own cowardice!"

"Look for death!"

The Frog Demon King was furious and slammed into him, and the iron sword in Yang Yifan's hand quickly stabbed towards the Frog Demon King.

Choke!

The Xuantie Sword stabbed on the Frog Demon King's body, making a sound of gold and iron, like a steel plate.

Yang Yifan secretly screamed that it was not good, he didn't expect the frog's body to be so hard, and a sharp weapon like the Xuantie Sword could not cut it without moving.

"Qinglan, run away!"

In the midst of danger, Yang Yifan did not forget to remind Su Qinglan to flee quickly.

The frog demon king screamed, although the Xuantie Sword couldn't pierce it, it also hurt to hit it, and this time the demon was furious, and he opened his bloody mouth and rushed towards Yang Yifan.

Yang Yifan raised his sword to block it, and when he touched it, he was directly knocked out five or six meters away, fortunately, the Creature Xingchen Jue's refining realm had been completed, otherwise the power of this collision would have killed him.

The Frog Demon King didn't give him a chance to breathe, and before he could stand up, he rushed towards him again.

Yang Yifan knew that this fierce battle must be more than lucky, but at least he had to buy Su Qinglan a little more time, so that she could escape further, but who knew that he glanced out of the corner of his eye, but saw that Su Qinglan was still motionless in place.

"Qinglan, why don't you leave! This frog is not easy to deal with, I won't be able to last long!"

As he spoke, the Frog Demon King had already come to the top of his head with a volley, like a hill about to give him a Mount Tai to press.

Yang Yifan didn't dare to slack off, put his hand on the ground, flew back three or four meters away, and as soon as he stood firm, he shouted at Su Qinglan: "Qinglan, run!"

Who knew that Su Qinglan turned a deaf ear, and threw something over with her backhand, Yang Yifan grabbed it, looked at it, but it was a bronze mirror, and asked strangely: "What is this?"

"Mountains and rivers mirror!"

Yang Yifan was about to ask what the use of this mountain and river mirror was, but the frog demon king didn't give him a chance to speak, and rushed towards him again.

This time, the frog demon king was really angry, his whole body was full of demonic energy, black qi was permeated, and there were many skulls flying up and down around his body.

Wow, magic!

This posture really frightened Yang Yifan, and he hurriedly jumped away, although his combat power was not as good as that of the Frog Demon King, but his speed was not inferior at all.

A man and a frog kept swimming, and the speed became faster and faster, and wherever they passed, the wind suddenly rose.

"Xiao Fan, don't just run, look at the back of the mountain and river mirror, there is a spell on it, you memorize the spell, use the mountain and river mirror to subdue this frog!" Su Qinglan shouted eagerly.

Yang Yifan said secretly: Little sister, are you stupid, since this mountain and river mirror is so powerful, why don't you just recite the spell directly, why do you throw it to me!

I thought so, but I still held up the back of the bronze mirror to watch.

There is indeed a large string of words on the back of the bronze mirror, and the font is clumsy, and Yang Yifan recognizes it as an ancient seal.

"It's good that I've read a book, or I really can't read it!"

Yang Yifan carefully identified the words on it while running, and ran two or three laps before memorizing the words on it.

"Stop!"

Yang Yifan said stop as soon as he said stop, and the frog demon king suddenly couldn't hold back and bumped into him, knocking him out.

Yang Yifan didn't care about the pain in his body, and raised the mountain and river mirror to aim at the frog demon king.

"The peaks and mountains gather, the waves are angry, 30,000 miles of rivers, 5,000 mountains, turn into my strength, kill!"

With the shouting of the incantation, the original turbulent wind instantly condensed, followed by it, as if the whole world was rolling, the air continued to compress this side, and it didn't take long for a mountain peak dozens of zhang tall to take shape, and the mountain peak quickly blasted towards the frog demon king, with the attack of the mountain peak, there was also a lot of water falling from the sky, and the waterfall flowed straight down and smashed on the body of the frog demon king.

The mountain peaks are pressed to the top, the flying stream is rushing, and under the double attack, the frog demon king can't move.

The Frog Demon King's body became smaller and smaller, and after a few minutes, it had become the size of an ordinary frog.

Yang Yifan grabbed it in his hand and said jokingly: "Little frog, don't sing fairy tales yet." ”

The frog demon king said with a bitter face: "I can't sing fairy tales, can I sing conquest?"

Yang Yifan laughed and received the frog demon king into the system.
