Song Jian looked at this sky-blue flying plane, the whole aircraft is streamlined and bird-like, the wings on both sides are extended backwards, which plays a role in maintaining the stability of the aircraft, and on the fuselage, a linear bulge is arched, which can effectively break the air resistance.

Moreover, the fuselage of this aircraft is made of blue corundum. Moreover, it is a large piece of blue corundum, that is to say, this flying machine is actually carved, and it is a secret method used by craftsmen to carve a huge piece of blue steel into such a flying machine little by little.

Blue stone is not too valuable stone, of course, in the eyes of ordinary people, blue stone is already very good, but although blue stone is good, it is not worth 500,000 medium-grade yuan stone. The advantage of this flying machine is that it is carved into a flying machine with blue stone as a whole, so that this flying machine is enough to block the full force of the Yin Yang Realm martial artist!

Moreover, all the designs of this aircraft are actually designed to maintain stability and forward thrust, which shows that the designers originally wanted to design this aircraft as a high-speed aircraft.

The smooth wings, the streamlined wavy stripes, the raised air-breaking lines, the triangular tail and the recessed cabin doors are all designed to speed at 300 meters per second. In other words, even if the speed of this aircraft can reach 300 meters per second, it will maintain a smooth flight state.

What is the concept of 300 meters per second, well, it is about the same speed as the speed of a martial artist at the beginning of the Yin and Yang Realm!

When the speed of a flying machine can reach the speed of a martial artist in the Yin Yang Realm, it is not only a flying machine, it can even be used as an escape tool, a defensive magic weapon, and an invincible magic weapon.

Therefore, Song Jian's eyes lit up when he saw this flying machine, but he estimated that this flying machine was worth at least one and a half million medium-grade yuan stones, and it could not even be bought with yuan stones at all.

However, to Song Jian's surprise, the speed of this flying aircraft was only one hundred and fifty meters per second, which was only a little higher than the speed of those ordinary flying planes, and much worse than the speed of high-quality flying machines.

However, after Song Jian sensed the flying circle inside the flying machine, he understood the reason, so he bought the flying machine without hesitation.

The people around saw that there was a fool who wanted to buy an ordinary flying machine that could no longer be ordinary, and it was a huge amount of money of 500,000 medium-grade yuan stones, so they surrounded him, and the old man looked at the flying machine with some pain, and finally sighed, and said: "Deal, our Blue Sky Pavilion, all items can be priced, of course, the price may be depressed." ”

Song Jian nodded and said, "Okay, then can we go into the house and talk in detail, my things are quite messy." ”

The old man nodded, and then asked a waitress to call a professional appraiser and walked into a secret room with Song Jian.

After Song Jian and the old man left, all the people gathered around, surrounding this sky-blue flying machine, and talked endlessly.

"Are they two big fools?" muttered a rich man with a puffed stomach, looking at the plane.

"Definitely. An ordinary flying machine, sold for 500,000 medium-grade yuan stones, who will be affected?" his companion chimed in.

"That's it, and that young man's acting is too different, how can there be 400,000 medium-grade yuan stones that are not sold, and they have to be bought for 500,000. What about 100,000 medium-grade yuan stones? Lao Tzu has to save for a lifetime. Another person joined the discussion.

In the end, everyone decided that Song Jian and Sun Changhao must be two big fools.

It's just that the three people of the Heavenly Machine Pavilion are still looking at this sky-blue flying machine with burning eyes.

"I still don't see any tricks," said the bearded man impatiently, "I think those two are insane." What's the matter, a broken flying plane, it's not flying fast, how can it be so expensive?"

The one-eyed dragon also looked at the flying machine in puzzlement, "The blue steel stone is carved out as a whole, and it is very strong, enough to withstand the full force of the Yin Yang Realm martial artist, but ...... This speed is really a little too slow, even if it can block a blow, it can't stop the ten swords, and when you encounter a martial artist in the Yin Yang Realm or a martial artist at the peak of the Four Levels Realm, it is still difficult to escape death. But 500,000 yuan of stone is enough to buy a good defensive magic weapon. ”

The one-eyed dragon analyzed softly, although he didn't know much about flying machines, but he could still see the basic Dao, "Overall, although this flying machine is excellent, it is definitely not worth 500,000 medium-grade yuan stones." ”

The fan man also came to the same conclusion, he squinted his eyes, and said, "I think there is only one situation, and that is that young man knows how to transform the flying plane." Every part of this flying machine can be called perfect, only the speed is a hard injury, if that young man can increase the speed of the flying machine, then 500,000 medium-grade yuan stones may really be worth it. ”

The bearded man sneered: "Third brother, don't drag it around. If you can increase the speed of the flying machine, then the young man will be able to build the flying machine by himself! Speed is the soul of a flying machine, and it needs to be proficient in the flying circle. I don't believe it, that kid, that Song Jian's, will be proficient in flying magic circles!"

The one-eyed dragon was also puzzled.

The folding fan man was also shaken by what the bearded man said, and suddenly, a flash flashed in his mind, and the folding fan in his hand was patted lightly, and he said in a low voice: "I remembered, Song Jian, Song Jian, hehe, if this Song Jian is really the Song Sword of the Yuntian Sect, all this, I'm afraid it's really possible." That kid may really be able to increase the speed of the flying plane. ”

......

At this time, Song Jian did not take out the 40,000 medium-grade Yuan Stones, but took out two five-grade mountain seals and seven flying swords and handed them to the appraiser.

The appraiser was a little stunned for a while when he saw that Song Jian had so many magic weapons, and then he looked at Sun Changhao in embarrassment.

Sun Changhao said: "What's wrong?"

The appraiser said, "Lord Hui, this ...... These are indeed good magic weapons, if they are combined, they are enough to have 500,000 medium-grade yuan stones, but they are ...... It's just that we don't need so many high-quality magic weapons. ”

At this point, the appraiser stopped.

Sun Changhao frowned, glanced at Song Jian, and then said, "It's okay, it will always be used, take it, as long as the total value is enough for 500,000 medium-grade Yuan Stones." ”

When the appraiser heard this, he couldn't help but pout, which was too generous.

Song Jian saw that the appraiser was embarrassed, and said with a smile: "It doesn't matter, if the seniors don't need so many magic weapons, the juniors still have some Five Elements Spiritual Liquid here, maybe they can be used." ”

As he spoke, Song Jian took out two hundred bottles of high-quality Five Elements Spiritual Liquid.

This Five Elements Spiritual Liquid is a specialty of the Yuntian Sect, and it has a very good effect on the disciples of the Five Elements Realm, and has almost no effect on the martial artists below the Five Elements Realm, and it is even more useless for the martial artists above the Five Elements Realm.

Song Jian also knew the characteristics of the Five Elements Spiritual Liquid, but there were no other treasures in the Demon Sacrifice Exchange Hall at that time, so Song Jian would naturally choose this Five Elements Spiritual Liquid, after all, the liquidity of the Five Elements Spiritual Liquid was stronger than that of Yuan Shi.

Seeing these two hundred bottles of the Five Elements Spiritual Liquid, the appraiser's eyes lit up, and he spoke: "This is okay, two hundred bottles of the Five Elements Spiritual Liquid, which can be priced at 200,000 medium-grade Yuan Stones, of course, the quality of these Five Elements Spiritual Liquid in your hands, little brother, can be valued at 250,000 medium-grade Yuan Stones." ”

Song Jian nodded, took back a mountain seal, and three flying swords, and said, "How about this?" Two hundred bottles of the Five Elements Spiritual Liquid, plus a five-rank mountain seal, and four five-grade flying swords. ”

"Enough is enough," the appraiser nodded hurriedly.

Sun Changhao saw that Song Jian was so reasonable, and he didn't feel that he liked it even more, and he hurriedly said: "Now that the transaction has been completed, can you go back to my question, little brother?"

Song Jian smiled: "I put away the flying machine, and I will answer the questions of my predecessors." ”

"Okay, okay, no problem. Sun Changhao accompanied Song Jian out of the secret room.

The waiter gave Song Jian a blue storage bag, with the words "Blue Sky Pavilion" written on it, this storage bag is specially used to store the flying plane, and there are also jade talismans for the use of the flying machine, as well as the maintenance products of the flying machine, etc.

Song Jian turned out the storage bag, and then put the sky-blue flying plane into the storage bag.

Sun Changhao saw that Song Jian had put away the flying machine, and his face showed a little painful look, and he immediately hurriedly asked: "Little brother, since you are willing to spend a huge amount of money to buy this flying machine, you must have seen the potential of this flying machine, but our Blue Sky Pavilion has gathered the wisdom of all the array mages and studied it for nearly a hundred years, but we have not been able to design the speed of this flying machine, little brother, after you buy it, how can you improve it?" Please don't shirk it, little brother, the old man knows, you must have a way to improve it." ”

Sun Changhao's eyes showed an excited look, he was indeed very excited, this blue stone flying machine was planned by Sun Changhao at the beginning, for this theoretical speed of three hundred meters per second flying machine, Sun Changhao worked hard, he knew that if this flying machine can really be designed, it will trigger a revolution in flying aircraft, at that time, the purpose of the flying machine will no longer be just transportation and rest, more importantly, when the speed of the flying machine surpasses the martial artists of the Siguan Realm or even the Yin and Yang Realm, it will become a murderous treasureA must-have for escape chase!

At that time, it will also be the time when Blue Sky Pavilion rises overnight!

It's just that this flying plane failed, a complete failure, so Sun Changhao moved this flying plane out, but he didn't expect to meet Song Jian to buy it. Sun Changhao saw hope in Song Jian's eyes as he looked at the flying array of the flying plane.

Song Jian coughed and looked around, and the people around him were all around them, listening stupidly.

The light in the eyes of the folding fan man flashed, and Song Jian felt a pang in his heart, he knew that this folding fan man might recognize himself, this guy was already very well-informed, but he was afraid that he had guessed his true identity.

Song Jian arched his hand towards Sun Changhao and said, "Senior, I have a method of improvement, and I also ask the secret room to discuss it in detail." ”

Sun Changhao excitedly took Song Jian's hand, regardless of his gaffe, and ran to a secret room with Song Jian.
