Qiu Rangtian glanced at his woman, hesitated slightly, and then flipped his palm, and a brocade box appeared in his hand!

"Take it to save your father-in-law, you are a good man!"

"What about Ling'er?" Liu Xie said!

"I'll find a way, if I really can't do it, I'll go to the One Sword Sect, and I hope that my senior brothers can give me a spirit stone for the sake of the friendship of the same family!"

"Where is that Xuanbing Grass?" Liu Xie said!

"What are you asking for?" Qiu Rangtian was puzzled, and at the same time there was some vigilance!

Xuanbing Grass is an elixir of heaven and earth, which can not only improve the cultivation of monks, but also increase the cultivation of demon beasts.

No matter how bad it is, he can sell it in exchange for sky-high wealth, so he can't be careless!

"Tell me where it is, I might have a way to return you a mature fairy grass!"

“。。。。。 Everyone in Qingyunmen looked at each other, obviously not believing Liu Xie's words, even Qiu Ling'er was silent, obviously not believing it!

"Although I don't know if you have any way to make the fairy grass mature early, I can take you to the place where the Xuanbing Grass is!" Jiaolong Dao, in fact, I discovered that Xuanbing Grass a long time ago, but I already have one in my stomach, so I didn't swallow it!"

Qiu Rangtian's face turned pale for a while when he heard this, but there was no way, how could he dare to compete with Jiaolong for food!

"Liu Xie, how are you going to return me a fairy grass!" Qiu Rangtian said in a low voice!

"I have a secret method that can ripen unripe fruits in advance, whether it is fairy grass or spirit fruit, it is effective!"

Liu Xie is not lying, the ripening technology of plants in modern science has long been perfected, whether it is mangoes, bananas or apples, they can be ripened long in advance, just in time to be marketed when the market needs it, and then make a lot of money!

Although the fairy grass has a fairy character, in the final analysis, it is just a plant that has absorbed the aura of heaven and earth, and it is not fundamentally different from the apples and bananas in the previous life!

"Ripening the secret method?" Qiu Rangtian frowned after hearing this, he had been in the cultivation realm for decades, and he had never heard of such a secret method, so he couldn't help but be suspicious, "Is there any basis for what you said?"

"Of course there is!" and then Liu Xie told him about the modern ripening method!

Qiu Rangtian was dazed by a lot of modern terms, if it wasn't for confirming that Liu Xie was a genius, he would probably think that he was facing a madman!

"Liu Xie, this herb is very important to my daughter, I hope you don't have illusions about it, otherwise I will die with you even if I fight for my life!"

Liu Xie is helpless, this old guy still doesn't believe in himself!

So, Liu Xie handed the Ruyi Stone to Qiu Rangtian again, and said, "How about we make a bet? If I can't ripen this Zhuxian Grass, then you will take back this Ruyi Stone." ”

When Qiu Rangtian heard this, his heart was shocked, Ruyi Stone was related to Liu Xie's father's life, he actually dared to take it out to bet, was he really sure?

"And what if you win?"

"If I win ... Liu Xie said this, paused, then looked at Qiu Ling'er, and said with a smile, "Then you will marry your precious daughter to me!"

As soon as the words fell, Qiu Ling'er's whole face turned red instantly, and she hid behind Qiu Rangtian with a sigh and didn't dare to show her head!

Qiu Rangtian thought for a moment, then said decisively: "Okay!"

He is a person from the past, so he can naturally see his daughter's thoughts, and he has long been in love with Liu Xie! This bet will not be lost by himself no matter what!

So, everyone jumped on the back of the dragon, and the dragon jumped up and rushed out a few kilometers in an instant!

The dragon can't fly yet, and it must turn into a real dragon before it can soar for nine days! But with its huge body and jumping ability, it can easily glide through the air for dozens of miles!

After a few moves, the dragon came to the destination! It was on the edge of a cold pool, and the cold pool was deep and bottomless!

As soon as everyone fell, they felt trembling all over, it was too cold! It felt like dozens of degrees below zero, and if it weren't for their strong bodies, they would have froze long ago!

Qiu Rangtian hurriedly pointed out and injected a warm current into Liu Xie's body, which was much better!

The Xuanbin grass was located in a wetland between the cold pool and the stone wall, and before he got close, he felt an amazing medicinal fragrance coming to his nose, and Liu Xie suddenly felt refreshed, and he had beaten all the elixirs!

To be honest, if it wasn't for agreeing to Qiu Rangtian, Liu Xie would really want to take it himself!

"Is this the punishment?" Liu Xiedao!

Qiu Rangtian nodded, and Qiu Ling'er looked at this fairy grass in a daze, full of girlish heart!

"Are you sure, if I ripen it, you'll marry my daughter to me!"

As soon as Liu Xie's words came out, Qiu Ling'er blushed again and hid behind Qiu Rangtian, who had an expression like a dead child!

Are you really enough, do you need to be reminded so many times?

Liu Xie woke up Xiaobei again and asked it to scan the structure of this fairy grass, and after confirming that this was a relatively special plant, Liu Xie was about to start ripening!

He asked the dragon to take a shot and collect the ripe fruits nearby, the more the better!

Modern botanical research has shown that the ripening of the fruit depends entirely on a substance called ethylene, which means that as long as there is enough ethylene, the fruit can be ripened quickly!

So how do you get ethylene? Is there a chemical instrument here that can extract it?

In fact, ethylene exists in large quantities in nature, as long as it is a ripe fruit, it contains a large amount of ethylene! Therefore, there is no need to extract ethylene at all, only need to put the ripe fruit and the unripe fruit together, which will greatly accelerate the ripening speed of the fruit, and also achieve the effect of ripening!

Of course, it's best to be in a sealed environment to maximize the results!

In modern times, many people seal apples and bananas together and ripen each other!

Soon, Jiaolong collected a large number of ripe fruits, and the fruits it spit out opened its mouth and directly buried the four of them in the fruits! Qiu Zhong picked up a mountain pear and took a bite, and was glared at fiercely by Qiu Rangtian!

Everyone was skeptical of this method, and Liu Xie didn't care, so he directly asked Jiaolong to turn these ripe fruits into slag and then pile them on top of the fairy grass!

In an instant, tons of ethylene were sprayed on the Xuanbing grass!

Then, under the stunned eyes of everyone, the Xuanbing Grass actually matured at a speed visible to the naked eye! It was only one year short of maturity, and under the stimulation of a large amount of ethylene, it became crystal clear almost instantly, which was a sign of maturity!

So everyone was stunned by this magical scene, and even Jiaolong was shocked. I didn't expect such a magical thing to happen in this world, it's breathtaking!

"Genius! You are really the most genius I have ever seen!" Qiu made Tian's mouth almost unable to open in surprise, and praised Liu Xie vigorously!

Liu Xie smiled and said nothing, looking like everything was under my control, and the Jiaolong who was watching wanted to slap him to death!

"Hurry up and put away the fairy grass, otherwise the medicinal power will be too strong after the year has passed!" Liu Xiedao!

Qiu Rangtian took out a jade box, carefully accepted the Xuanbing Grass and put it in! Then he returned the Ruyi Stone to Liu Xiedao: "You have won again, you take the Ruyi Stone, go and save your father-in-law!"

Liu Xie looked at the sky, it was already the second night, there were only twelve hours left before the three-day period, and it would take nearly ten hours to walk normally from here to the Confucian Academy.

Liu Xie thought about it, glanced at Qiu Ling'er in a sneer, and the horn of his mouth flowed out again!

Qiu Rangtian frowned and said, "I know what you're thinking, but Ling'er can't go with you yet!"

When Qiu Ling'er heard this, she was anxious, and screamed angrily: "Dad, how can you go back on your word!"

As soon as the words came out, I suddenly felt that something was wrong, how could a girl be so unaware (such as) (hungry) ashamed (like) ashamed (thirsty), so her face was red again!

"It's really a big woman, wait until I refine the Xuanyuan Pill for you and improve your physique!"

Liu Xie looked at Qiu Ling'er and couldn't help but be overjoyed, this flower-like beauty will be his own in the future!

Can this happen again in the future?

The matter of Xuanbing Grass is over, and everyone has returned to Qingyun Peak again!

Jiaolong said: "Liu Xie, I owe you a favor, if you encounter any unsolvable difficulties in the future, go to the cold pool at the bottom of the mountain to find me, I will practice here in the next few hundred years and strive to turn into a dragon!"

Qiu makes the sky happy, there is such a powerful dragon guarding here, and the average Xiaoxiao will never dare to make a second time!

So, Qiu Rangtian also said: "Liu Xie, I also owe you a favor, you will find Brother Jiaolong for major matters in the future, and just look for me for small matters!"

"Yes, father-in-law!" Liu Xie was overjoyed, this time he really made a fortune!

Qiu Rangtian was speechless, my daughter didn't marry you yet, so she started calling her father-in-law!

"It's not easy to marry my daughter, you have to accept my three tests, and you can only be my son-in-law, you go and save your father-in-law, come back in three months!"

"Daddy, I'll send my husband off!" Qiu Ling'er said!

Qiu Zhong was speechless, the dog man and woman had not yet married, and they began to call their husbands!

Since then, Liu Xie said goodbye to Jiaolong and Qiu Rangtian and began the journey back to the Confucian Academy!
