I can rewind time to prevent death

After sitting for a moment longer, Shi Yanan rushed to fetch Yan Junze's hand-drawn blueprints and sat down to study them, frequently consulting the drawings and asking Yan Junze about the purpose of specific design elements.

Their voices were low, but Yan Junze could tell that Shi Yanan truly loved manufacturing weapons, was very dedicated, and also offered some of her own insights.

After talking with her, Yan Junze felt he should have a rough idea of Wan Shouguang's thoughts on how to manufacture the Black Spirit Umbrella, since Shi Yanan was a disciple he personally trained and was very familiar with his work methods and viewpoints.

After waiting for some time, Wan Shouguang manually tested the data on the computer, and once he confirmed that it could be constructed, he began to establish the construction module.

Setting up the construction module took some time, so he poured himself a glass of water and walked over, while Shi Yanan quickly got up and stepped aside.

After sitting down, Wan Shouguang said to Yan Junze, "Based on my experience, although I've never made a similar weapon before, the fundamental data should be correct, and at most, some minor adjustments might be needed after testing."

"Thank you for your trouble, Uncle Wan," said Yan Junze.

Wan Shouguang waved his hand, saying, "No, it is we who are troubling you."

Shi Yanan, listening on the side, was completely bewildered and did not dare to ask.

Wan Shouguang continued, "Based on the material parameters I've provided, and after the data has been fully simulated by the computer, the actual production phase is very fast. It's mainly the data adjustment that needs to be meticulous."

"A hundred percent simulation?" asked Yan Junze.

Wan Shouguang nodded, "Yes, completely identical. If the simulation is successful, the produced item will definitely be the same. But I need to ask Old Zhang about the specific energy data."

"The balance of Strange Energy, indeed, Uncle Zhang has the final word on that, I don't quite understand it either," Yan Junze said.

"I'll ask him tomorrow, no time today," Wan Shouguang said as he put his cup down and added, "Come with me."

The two approached the computer, where only a mass of parameters was displayed on the screen.

Wan Shouguang, pointing at the screen, said, "These data are for all the raw materials, including the Ultra-High-Strength Lightweight Alloy and EPU high-polymer material yarn membrane you know of. The lightweight alloy serves as the framework of the umbrella, while the yarn membrane is the central area of the umbrella surface, capable of projecting moonlight to its maximum extent and storing energy. The periphery of the umbrella surface uses another type of Anti-Bone Fascia, an ultra-tough film. The tensile strength of each film is sufficient to block most bullets over short distances."

He paused, then asked, "Regarding the Black Spirit Umbrella, all these raw materials are included. For the tip of the umbrella, do you want it to be equipped with a spike, or an ejection device?"

After thinking, Yan Junze replied, "Could we equip it with a chain ejector, with a spiked tip and sturdy, elastic chains at the end? Even if it is shot out, it could be pulled back directly and reused."

Wan Shouguang thought briefly, "That's possible. In that case, the umbrella handle will need to be designed as hollow and include launching and retrieval devices. I have an existing equipment design that, with slight adjustments, should fit into the umbrella handle."

"It's smoother dealing with an expert," Yan Junze thought to himself. "This way, the problems encountered mid-way can be easily resolved, saving a lot of trouble."

No sooner had he finished his thoughts than Wan Shouguang had gone back to the computer to reload the data for the chain ejection mechanism, while Shi Yanan recalculated the data on another computer.

They finished in about half an hour.

At that time, Zhang Chengjing had finished a meeting upstairs and arrived.

Before he had a chance to speak with Yan Junze, Wan Shouguang said, "Perfect timing, I was planning to ask you for the data tomorrow."

"What data?" Zhang Chengjing asked.

Wan Shouguang, clearly very familiar with him, took his arm and brought him to the computer, pointing at the 3D model of the Black Spirit Umbrella, he said, "Yan told me that you mentioned a balance of energy achieved inside the umbrella after being reinforced by three types of power. Could you give me a general range of data values now, so the simulation can be more precise?"

Zhang Chengjing had actually come to call Yan Junze upstairs and to check the progress of the weapon design. After hearing what Wan Shouguang said, he nodded, turned to Yan Junze, and said, "Give me your Turquoise."

At the mention of "Turquoise," Wan Shouguang's pupils contracted, and his heartbeat quickened.

This thing was very important. Seeing the Turquoise, he felt as if he could see the future picture of his son reuniting with him and his wife.

So now that the Turquoise was in Zhang Chengjing's hands, he felt an inexplicable anxiety. After all, Zhang Chengjing was very strong, and if he damaged the Turquoise or discovered that he intended to use it to collect his son's strangeness afterwards, what then?

Zhang Chengjing, however, did not notice Wan Shouguang's expression and said, "Open the isolation room."

Shi Yanan did as instructed, opening the door of the bullet-proof glass grade isolation room, Zhang Chengjing, holding the Turquoise, stepped inside, and then Shi Yanan closed the door from behind.

This kind of door automatically locked from the outside; it could only be opened with a key or a switch on one's body with the proper sensor.

Since the bullet-proof glass was extremely transparent, as Zhang Chengjing stood in the middle of the isolation room, he raised the Turquoise spread in his palm aloft.

Everyone outside the isolation room also focused on the piece of Turquoise at that moment.

Soon, the Turquoise in the palm began to move slightly as if something from underneath nudged it, causing it to flip over.

Immediately, a wisp of black vapor rose from the surface of the Turquoise, swiftly coalescing into a figure. As the figure took shape, it kept dispersing and then condensing again, barely maintaining the form of an upper body.
