"The basic exercises for cultivating immortals are actually similar to the martial arts luck exercises in the mortal world, first of all, you have to be able to induce qi into the body, open the important points in the body, and let the breath condense in the dantian without dissipating."

"You know how to martial arts luck exercises, and your Ren and Du two veins have also been opened, and when you are twenty years old, it is completely too late to cultivate the exercises of cultivating immortals." Yao Guangchai said softly.

"Great! Yaoguangchai, I have one last question: Excuse me, are you willing to accompany me to Yunmengze to find other ancient immortals? Xiao Qiongzhi was very happy and asked with a smile.

"Of course I do. We are now in a relationship of glory and humiliation! Yao Guangchai said with a smile.

Xiao Qiongzhi was relieved, and turned to Gu Ling and said, "Senior Gu, I communicated with my hairpin just now, and it promised to accompany me to Yunmengze to find ancient immortals when I have time. ”

"Okay, then let's try it now, can you use this flying machine you made someone."

"If it works, I'll give you a month to look for the four things I just mentioned, and then, in a month's time, my husband and I will return to my planet in this flying machine." Gu Ling said.

After speaking, she put away the two Ancestor Realm-level ancient immortal artifacts in her hand, reached into the mouth of the bulging cloth bag that she had taken out of the ring first, took out a dozen or so fist-sized spirit stones, and threw them into the fuel room of the aircraft engine.

Then, she stretched out her thumb and forefinger and flicked it lightly at the dozen or so fist-sized spirit stones.

The dozen or so fist-sized spirit stones were like lit stars, emitting dazzling light.

She quickly put away the large cloth bag, closed the door to the engine's fuel room, and walked over to the location of the turbofan, listening carefully.

It just so happened that the engine turbofan was working at this time, and there was a fast and heavy turning sound.

And, the sound of the turning, became more and more urgent.

A satisfied smile immediately appeared on her face, and she motioned for Xiao Qiongzhi to follow her and enter the cockpit in front of the aircraft together.

She sat in the cockpit pilot's seat, and Xiao Qiongzhi sat in the deputy seat next to her.

Before she sat down, Xiao Qiongzhi saw her take out several oval mirrors from her space ring and place them on the gunwales directly in front of the cockpit.

In this way, it will obviously block the view of the aircraft flying forward.

Xiao Qiongzhi was puzzled, and the next moment, she found that after the oval mirrors were placed, they were like a monitored computer that was turned on, showing the situation in front of the aircraft, the wings, and the tail of the aircraft in real time, as well as the working conditions of the engines in the aircraft.

It seems that these mirrors are not ordinary mirrors, but some special magic weapons.

Xiao Qiongzhi couldn't help but look forward to Gu Ling's next operation.

At this time, Gu Ling had already put his hand on the steering wheel.

She held the steering wheel with a calm expression, gently pressed the driving switch in the middle, and then drove the aircraft slowly away from the huge steel shed of the Ministry of Engineering to assemble the aircraft, and drove outside.

The red apricot had sharp eyes, rushed to the door of the tall gate in front of the steel shed at the right time, and ordered the guards of the Ministry of Works waiting at the door to open all the gates.

Soon, the aircraft passed through the gate at an increasing speed and headed for the runway outside the gate.

Originally, the runway was nearly 1.5 kilometers long, however, it may be because the aircraft was burned with spirit stones and had extraordinary power, but in fact, the aircraft had already taken off and risen into the sky less than 100 meters away from the runway.

Moreover, as time passed, the aircraft flew higher and higher, and in about a short time, it had risen to an altitude of more than 10,000 meters.

However, this height seemed to be far from enough for Gu Ling.

Because, she put it in a mirror in front of her, and began to send a crisp child's voice command: "Gu Ling, accelerate, the current position, is still one million and three hundred thousand meters away from the location of the space coordinates you arranged last time, and it is estimated that at the current speed, it will take nearly ten hours to arrive!" ”

"No, I'm in a test flight now, and I don't want to go back, Qinglong, you take a closer look and test it, and see if there are any problems with this aircraft's accessories, materials, and flight performance? Does it have the power to bring us back to our planet? ”

The person who made the crisp voice, Qinglong, pondered for a long time before saying, "Yes, this flying machine, its accessories, materials, and flight performance are far better than our original flying machine. ”

"Especially the material, its skin is an aluminum-lithium alloy forged with aluminum, and the load-bearing frame is duralumin and super duralumin."

"The fuselage rails and wing spars are a special alloy of metal (titanium) forged with steel, and the landing gear is ultra-high-strength steel."

"The flat tail and vertical tail are materials that are similar to glass (fiberglass) and carbon (carbon fiber composites)."

"The engine fan is a special alloy of metal (titanium) forged with steel, and the first stages of the compressor are also a special alloy of metal (titanium) forged with aluminum."

"The latter stages of the compressor are alloys forged from this special metal (high-temperature titanium) with steel, and the flame barrel and turbine are heat-resistant alloys forged from three special metals (high nickel, high chromium, high molybdenum) and steel."

"The engine casing is stainless steel, and the portholes are made of a special substance (polycarbonate)."

"No one on our planet has yet had the ability to forge such a variety of alloys and special substances on this aircraft."

After listening carefully, Gu Ling's eyes lit up, and he said to Xiao Qiongzhi: "Princess Zhong Ling, you heard the conversation I had with Qinglong just now, right?" ”

"Wait a minute, you can ask you craftsmen of the Great Xiao Ministry of Industry to collect the special materials needed for forging the fuselage rails, wing spars, engine fans, compressors, the first and last stages, as well as the flame barrels and turbines, as well as the forging methods, and give them to me."

"I should be able to help you exchange a large number of spirit stones on our planet with these."

"Ancient predecessors, these are all state secrets that belong to our Great Xiao, I have no right to call the shots, in fact, it is to make this flying machine for you, I finally obtained the consent of His Majesty the Emperor, saying that I wanted a toy flying machine myself, so I had to be allowed to make it."

"So, I'll start with the four things you mentioned earlier and get a way to exchange them for spirit stones." Xiao Qiongzhi said with an embarrassed face.

Although she needed spirit stones very much, and although the materials and forging methods used to forge these parts of the aircraft were all completed by the craftsmen of the Ministry of Industry led by Wei Feng, it took no effort to get them, but as she said to Gu Ling, these were all state secrets that belonged to Da Xiao.

Not to mention that she still has her grandfather Xiao Xuanliang, who is the emperor of Da Xiao, on her head, she is in charge of the Da Xiao country, and she can't easily reveal any secret weapons that belong to the core domain of Da Xiao, or anything else.
