Chapter 494

Weng xuanzi, hearing what Qin Yichen said, nodded lightly, hesitated for a moment, looked at Qin Yichen and said, "this time, we'd better keep a low profile. After all, the story of the dragon has spread all over the mainland, and the other three suzerain states are also very curious. Fortunately, they don't know that the three of us are going to the polar wilderness. If they know, they will certainly block it, So, you and Luo Bing should not call me the right front special envoy this time. My name is Weng xuanzi. "

Qin Yichen had known Weng xuanzi's name at the last banquet, but she didn't know her surname. Today, she knew her full name. It sounds like a very gentle and pleasant woman's name.

Immediately, Qin Yichen asked: "why do other suzerain countries block us from going to the polar wilderness?"

Weng xuanzi explained: "the competition among the four major countries is very fierce. After several large-scale battles, today's relatively balanced situation has come into being. Although everyone does not take the initiative to break the balance, every country is eager to break the balance and occupy more resources, but there has never been a chance, Everyone's understanding of this world remains in the traditional understanding of the immortal cultivators. They think that this is a planet for cultivating immortals, and there will be no existence beyond the immortal cultivators. But now there is a god beast, and it is not a god beast lying in this world waiting to rise. It is really a god beast that lives in this world and can even move freely. Therefore, everyone is in danger, If they know that we have been ordered by the beast to go to the polar wilderness, they will be afraid that we will take this opportunity to expand our power, so they will try every means to stop us. "

"I see." Qin Yichen nodded, looked at Weng xuanzi and said with a smile, "I'll listen to you, miss xuanzi."

Weng xuanzi laughed with satisfaction and said, "OK, in order to keep a low profile this time, no one will see us off. Let's go straight out of the holy city and go all the way north."

………

Three people went out of the holy city side by side. As soon as they got out of the holy city, they came to the huge platform in the north of the holy city. Weng xuanzi said to Qin Yichen and Luo Bing, "I will protect you two with aura and take you two to fly, just like we did when we came here."

Qin Yichen said in a hurry: "don't worry, miss xuanzi. Let me try my new magic weapon."

"New magic weapon?" Weng xuanzi looked at Qin Yichen in surprise and said, "is it the magic weapon that you have been practicing in your room today? What is it for? "

Qin Yichen smiles, takes out the shuttle and says with a smile, "look. That's it. "

"This..."

Weng xuanzi frowned and looked at the strange thing in Qin Yichen's hand. After a while, she asked, "is this a boat?"

Qin Yichen can't help but curl his mouth. What's the matter with the boat? It's obviously a missile. How can it be regarded as a ship? Does the ship have a tail and wings?

However, Qin Yichen once again saw that the hollow in the middle of the cylinder was really like a canoe, not to mention Weng xuanzi, who didn't know what a missile was.

Immediately, Qin Yichen said with a smile: "this is also a boat, but this thing is a spaceship."

With that, Qin Yichen recited his mental skill and threw out the Yufeng shuttle. With a whoosh, the Yufeng shuttle expanded into a huge object with a length of nearly eight meters.

Qin Yichen put some aura into the Yufeng shuttle to keep it in suspension. He said to Luo Bing, "Bing Er, you go up first."

Luo Bing has long wanted to see Qin Yichen's "Craftsmanship". Hearing what Qin Yichen said, he jumped directly into the inside of the Yufeng shuttle, and Qin Yichen also jumped in. At this time, Weng xuanzi looked at the two people in the Yufeng shuttle with a puzzled face and asked curiously, "are you going to fly with this thing?"

"That's right." Qin Yichen said with a smile: "it's much easier than flying with imperial sword. After all, it's a magic weapon specially made for flying."

Weng xuanzi shook her head helplessly and said, "well, I'll try my best to fly slower. You'll follow me. Let's try first. If the speed is too slow, I'll take you to fly."

Qin Yichen once calculated Weng xuanzi's flight speed. Although he can't measure the speed accurately, through the visual inspection when moving, it is at least 6000 km / h or 7000 km / h. even if he takes two people to fly, the speed can be guaranteed to be around 4000 or 5000 km / h. However, he doesn't know how fast his own Yufeng shuttle can be. If it can keep up with Weng xuanzi's own speed, That's enough to satisfy him.

Even though Weng xuanzi took off immediately, he started flying at a speed of about 1000 km / h.

In Weng xuanzi's opinion, Qin Yichen's current strength and flying speed can reach his own speed now, which is very good.

However, after Qin Yichen placed 20 Bi Chao stones in the Yufeng shuttle, he started his upgraded Yufeng array. In a moment, the Yufeng shuttle rushed out like a rocket!

Weng xuanzi has already shaken off Qin Yichen for tens of kilometers in a twinkling of an eye. However, Qin Yichen has caught up with her very quickly. The speed is so fast that she is stunned!

At the beginning of the acceleration stage, Qin Yichen estimated that his speed would be at least two or three thousand kilometers per hour. Then, as the array was running faster and faster, the speed was still improving.

Weng xuanzi didn't expect Qin Yichen to catch up so quickly. He hastened to increase his speed, which was about 4000 km / h. However, Qin Yichen didn't have any extra power. Yufengsuo gradually caught up with him, and was constantly narrowing the distance between him and Weng xuanzi.

"This guy..." Weng xuanzi turned her head and looked at it. She couldn't help wondering, "what kind of magic weapon has he refined? Why can he move so fast? This guy is not afraid to fly at such a fast speed, and he will soon exhaust his aura in his body! "

Whether it's the world of immortals or the world of science and technology, the laws of physics are constant, just as there is gravity and air resistance in the world of immortals. People who have life experience know that a person with good physical strength can ride at least tens of kilometers with ordinary uniform speed, but when he plays with his life and kicks wildly When he tries to improve his speed, his physical strength consumption will increase exponentially. It's impossible for him to stick to three or five kilometers at high speed. Therefore, the faster he runs, the more energy he consumes, whether it's the use of technological power or spiritual power.

Weng xuanzi is very worried about whether Qin Yichen will be exhausted after a while. However, Qin Yichen gives her the best answer with practical actions.

can't!

Yufengsuo has an excellent aerodynamic structure. Its wind resistance can't be compared with that of the immortal cultivator's sword flying. There is no immortal cultivator's flying posture of flat body and head forward. Therefore, their whole body is a wind resistance area. However, Qin Yichen's yufengsuo is like a sharp bullet, piercing the air and flying at high speed in the most labor-saving way.

In addition, Qin Yichen's yufengsuo has a much bigger transformation from spiritual power to power than that of Yujian flying. In terms of aerodynamics, the gap between the yufengsuo and the immortal cultivator is like the gap between a Lamborghini and a golden cup bread. In terms of power system, it is like the Lamborghini using the engine to directly output power for rear wheel drive, And the golden cup bread is to output the engine to a fan, and move forward through the wind energy brought by the fan. In this way, the conversion ratio of the former must be higher.

Therefore, Qin Yichen's rapid flight, the spiritual power output of the 20 Bi Chao stones is not very high, which is much more labor-saving than flying directly with the spirit sword.

At this time, Weng xuanzi was surprised to find that Qin Yichen was still speeding up! The distance between him and himself was getting closer and closer. To her surprise, Weng xuanzi didn't want to be surpassed by a foundational cultivator with his refined magic weapon. So she immediately clenched her teeth and increased her speed to the extreme. In an instant, her speed even reached the limit of 7000 km.

Weng xuanzi is burning her limit. This kind of speed, which is almost used to run for life in battle, is used by her on the road. The speed of Reiki consumption is very large.

At this time, Qin Yichen found that the rotation speed of the array has stabilized, and the speed has not increased any more. He can't help but find out the root cause. A moment later, he found that the reason why the rotation speed of the array has stabilized is not that the array can't bear higher rotation speed, nor that red copper can't bear higher speed, But the output speed of Bi Chao stone's aura has reached the limit.

Although Bi Chao stone is a spirit stone, it doesn't mean that it can output as fast as it can. Even if it's a barrel full of gasoline, the speed of gasoline flowing out is limited by the caliber of the barrel. Therefore, in this way, the spirit output reaches the extreme, and the rotation speed of the array also reaches the extreme.

Qin Yichen's heart moves, since the 20 Bi Chao stone's aura output is so big, then he simply increases the number of Bi Chao stone!

This is like paralleling several batteries to increase the output current of the circuit.

Another 20 Bi Chao stones were connected to the array by Qin Yichen, and 40 Bi Chao stones provided spiritual power at the same time, which doubled the output speed of spiritual power. In a moment, the speed of the wind shuttle suddenly increased!

Originally, Weng xuanzi was constantly widening the distance between herself and Qin Yichen. However, after Qin Yichen put in another 20 spirit stones, her speed of expanding the distance began to slow down obviously. After a moment, she began to be equal, and the two remained relatively static.

Qin Yichen investigated the situation of yufengsuo at this time. The temperature of the front end was a little too high, which had already made the red copper soften. If he went on like this, he was afraid that the temperature would get higher and higher, and he could not help complaining about himself. Why didn't he expect to use a certain amount of black iron essence to strengthen the front end, so that it could have higher heat resistance? However, he was competing with Weng xuanzi at the moment, Her own wind shuttle has reached the extreme of her speed. If you just give up, wouldn't you give up halfway?!
