Walking into the Jail, it looked exactly the same as before on the surface.

However, after passing through the corridor and entering the various cells, the interior was completely different.

In the large cell, lived a Third-Rank Refiner. He refined vehicles here, and they were transported away after completion.

The smaller cells were used as storage rooms, holding various Materials for refining Winged Vehicles.

“Here, including myself, there are seven Third-Rank Refiners. The fastest can refine one vehicle in three days. The slower ones take seven days,” Elder Tian Shu introduced.

“That doesn’t seem very fast,” Qian Duoduo hesitated, speaking the truth.

“Indeed, it’s not fast,” Elder Tian Shu didn’t get angry at all.

“Like me, I can’t even guarantee 100% success for the vehicles I refine. During vehicle refining, connecting the wings and the vehicle body is the most difficult part; a slight oversight can easily lead to producing defective products.”

“Can we first refine Puppets, and then use the Puppets to refine vehicles? That would increase efficiency.”

These days, whenever Qian Duoduo had free time, he studied the Puppet scroll, always feeling an urge to refine Puppets.

Tian Shu shook her head, “The lowest grade of Puppet is a Dan artifact. A Dan artifact Puppet cannot refine a Dan artifact Winged Vehicle. As for Xuanshi Puppets, or higher grades like Spiritual Artifact and Treasure Artifact Puppets, we cannot refine them.”

“Elder Tian Shu, can I study the Winged Vehicle’s Magic Treasure?”

“No problem. You are a Four-Rank Refiner and have the right to read all Magic Treasures in this sect’s Artificer Hall.” Tian Shu handed him a Jade Slip.

“If you need manpower, you can also recruit ten First-Rank Artifact Refiners. You will pay the recruitment fees yourself, but they won’t be of much help to your vehicle refining.”

Qian Duoduo walked to the cell he had previously lived in and, seeing it empty, said to Elder Tian Shu, “I’ll stay here. I’ll trouble the Elder again if anything comes up.”

After closing the cell door, he surveyed the cell.

This cell was still the familiar stone cave.

The four sides of the cave were natural rock, with traces of chiseling. On the ground and stone walls, there were still many small holes he had poked while practicing controlling the Spirit Chicken legs.

The cell had only one door and one window on the door.

At this moment, Jin Buhuan still lay motionless in the Golden Toad, just like on the first day, with a faint, ethereal shadow floating around him.

Unlike before, the ceiling and four walls of the cell were fitted with many fluorescent stones.

The well-lit cell was much warmer and far less gloomy.

Qian Duoduo sat down in his usual spot. After setting up a shielding Formation around him, he said to Liu Boli inside the Golden Toad, “Master, how do you think I fell down back then?”

Qian Duoduo transforming into Jin Buhuan was through the stone wall of this stone cave.

Did this stone wall lead to his hometown, You Sha Village?

Qian Duoduo had asked Liu Boli this question countless times in the Jail.

Liu Boli had also investigated countless times, but found no results.

However, Liu Boli was at the Golden Core Great Perfection at that time. He is now at the Heavenly Human Initial Stage, a full two great Realms higher, so he wondered if he could find anything.

Liu Boli floated out of the Golden Toad, still dark and thin, suspended in the air.

Only, Qian Duoduo was no longer afraid of him; on the contrary, he was Qian Duoduo’s Master, his most solid reliance.

A reliance of absolute trust and eternal mutual assistance.

Liu Boli sniffed the surrounding Qi, clearly a little excited himself.

He was knowledgeable and experienced, and equally puzzled by Qian Duoduo’s inexplicable descent from the sky.

His powerful Spiritual Awareness spread out, covering every inch of the cell, penetrating ten zhang, a hundred zhang, a thousand zhang into the stone wall…

Looking at his serious face, Qian Duoduo was also very nervous.

After a long time, Liu Boli withdrew his Spiritual Awareness and shook his head, “My Spiritual Awareness did not reach the end of this stone wall, so I still don’t know how you came to the Refining Spirit Sect. However, if we have time to go out of the sect, looking from the general direction, we should be able to find the village where you were born.”

Qian Duoduo breathed a sigh of relief, feeling both disappointed and relaxed.

Perhaps this is fate; you may never know where the hand that pushed you to change space-time came from, whose it was, or for what purpose.

Liu Boli turned to Qian Duoduo and said, “However, even if we go to the village where you were born, we may not find the answer. This mystery, perhaps, will naturally unravel when you become powerful one day.”

Qian Duoduo smiled, “If I can’t solve it, I won’t. Anyway, I am Qian Duoduo, and I will always be Qian Duoduo myself.”

“I hope so,” Liu Boli said, then returned to the Golden Toad.

Qian Duoduo opened the Magic Treasure given by Elder Tian Shu and began to study the refining of the Winged Vehicle.

The Winged Vehicle is generally divided into four parts: the vehicle wings, vehicle body, vehicle bottom, and vehicle control.

The vehicle wings are a pair of real Spirit Birds’ wings, providing propulsion for the Winged Vehicle.

The size and strength of the wings largely determine the grade of the Winged Vehicle.

The most common vehicle wings in the Refining Spirit Sect are Spirit Crane wings, with hundreds of pairs in stock. The most precious are Divine Eagle wings, with only one pair in stock.

The vehicle body is a structure for Cultivators to sit and rest comfortably, shielding them from wind and rain. The Magic Treasure listed dozens of different Materials.

The vehicle bottom is the part that protects the Cultivator and the Winged Vehicle. Especially during flight, it is very susceptible to attacks from below. A sturdy yet lightweight vehicle bottom is equivalent to the Winged Vehicle’s armor.

The Winged Vehicle uses Spiritual Qi as its drive. The storage, transmission, and regulation of Spiritual Qi are achieved through the vehicle control.

Refining a Winged Vehicle is difficult due to the many types of Materials used, high requirements, and complex assembly.

There are three stages that severely test one’s control over Spiritual Qi: first, the refining of the vehicle wings; second, the assembly of the vehicle body and vehicle bottom; and third, the connection of the vehicle control.

Without the level of a Third-Rank Refiner, one cannot pass these three hurdles.

There are no shortcuts in Artifact Refining; one can only learn from failure.

Having memorized the Magic Treasure, Qian Duoduo took out his refining cauldron, lit the fire, and began to forge the Materials one by one.

Because he was refining a Winged Vehicle to transport Golden Ox, Qian Duoduo chose the four-winged bird wings with the greatest power in the warehouse.

The four-winged bird is a bird with the strongest continuous flight ability. It has two pairs of wings; one pair can fly while the other rests. When one pair gets tired, the other pair takes over.

Of course, when attacked, both pairs of wings fly together, allowing for quick escape.

However, Artifact Refiners who refine Winged Vehicles do not particularly like four-winged bird wings because more wings also mean greater difficulty in refining and in connecting them to the vehicle body and vehicle control. Precisely because everyone disliked using them, over a hundred pairs of four-winged bird wings were stored in the warehouse.

After refining the vehicle wings, Qian Duoduo changed the structure of the vehicle body.

The original Winged Vehicle body was designed with four seats. He was transporting Golden Ox, so the seats were useless. Except for the seat of the Cultivator controlling the vehicle, all other seats were removed.

Qian Duoduo calculated and enlarged the vehicle body to accommodate ten adult Golden Ox.

He thought to himself, when Elder Tian Shu saw the vehicle body, she would definitely say, “Are you crazy?”

Such a massive vehicle body, plus ten Golden Ox, whether it could fly would depend on both the wings and the vehicle control.

If the lift generated by the wings was insufficient, the Winged Vehicle wouldn’t be able to fly. And if the Spiritual Qi supplied to the vehicle wings was insufficient, the Winged Vehicle also wouldn’t be able to fly.

In addition to increasing the Spiritual Qi storage, Qian Duoduo engraved Golden Winged Birds on all the Spiritual Qi transmission pipelines. When Spiritual Qi passed through, it would automatically accelerate.

If Qian Duoduo hadn’t Cultivated the Turning Stone into Gold Art, he truly wouldn’t have been able to solve this vehicle control problem.

As for the vehicle bottom, he greatly simplified it, making it almost as thin as a piece of paper. The weight saved perfectly offset part of the increased weight of the enlarged vehicle body.

Looking at the refined vehicle wings, vehicle body, vehicle bottom, and vehicle control, Qian Duoduo rubbed his hands.

It was time for the assembly stage; success or failure depended on this final hurdle!
