For the next three days, Ji Feng and the others would go to Yan Yan's research institute every day to help, and the tears were also unable to take out their hands to help Ji Feng and them because they had to prepare for the Daba Star Festival.

Although the manpower has been reduced a lot, Ji Feng is more willing to do this, she told Tears that she has come to Yan Ling's side frequently in the past few days just to help Yan Yan and them test the new machine, after all, only in this way will Tears and the others not have unnecessary suspicions.

Today is the three-day deadline.

Ji Feng carried the shell of a new type of time shuttle machine and placed it on the right hand wall of Yan Ling, who was squatting on the ground and working.

"The shell of this new model looks much more pleasing to the eye than the previous vending machine, the previous one is not only ugly, but also has four sharp corners and rests on the hand. ”

Yan Ling stopped what he was doing and gave her a blank look, then stood up and patted the shells of several new models on his right. "I didn't just change the model just to make it look good. ”

After Yan Yan's explanation, Ji Feng understood the power of this new model.

At this point, all time shuttle machines have completely shed the shape of their previous vending machines. After more than two months of frequent generational changes, Yan and Lance finally drew the shell of the final version of the time shuttle.

This is a coconut-round shell that looks like an egg, and the whole body is raised and smooth, with a curvaceous beauty. The paint has also been changed from pure black to silvery, which Yan says makes it easier to hide himself in the cracks.

There is still a palm-sized transparent glass in the center of the front of the machine, but this glass is fundamentally different from ordinary glass, because its main material is actually a biological synthetic substance, which is not only extremely hard, but also can be linked to the internal database of the time shuttle, which can detect the environmental indicators outside the cabin and the surrounding situation in an all-round way.

Not only that, but it also has a simple mimicry system that can even simulate any substance if the operator wishes, so that people outside the aircraft are not aware of what's going on inside the cabin, while the operator inside the cabin has a clear understanding of what's going on outside.

In addition, the new crosser does not need to be equipped with a cooling system, and there is only a small thermostat on the back, so the overall body of the new model is a full circle smaller than the previous black box type. In addition, the frame that used to hold the body in the cabin has been replaced with soft cotton cushions, so that the person lying inside can feel more comfortable.

The operating system is a state-of-the-art digital face-to-face projection that wraps around the face so that the operator can see everything around the outside with a slight turn of the head. As for the digital control panel, it is set up on the facets on both sides of the cushion, which makes it easier for people who are lying down to operate.

Before, he was still saying that there was not enough time, but now that he has built a crossing machine of this magnitude, Ji Feng really can't understand the concept of time urgency that Yan Cheng said.

Just as Yan Ling and Ji Feng finished explaining the function of the latest shell, Lance, who was in charge of another project, took Li Qiang and the others to get the original piece of the machine they were responsible for and sent it over.

The part they are responsible for is the 'engine' of the time shuttle, which is the main part that converts the 'primordial' element into its own energy.

Because Yan Ling and Lance have already built the perfect engine, although it sounds very complicated, it doesn't require too much professional knowledge to manufacture this part, just repeating mechanical actions, so Yan Ling doesn't need to be involved.

The shell that Yan Cheng was responsible for was the most complicated part, and she had to write all the functional code that needed to be used in the next three days. Just like the constant temperature function, this is to ensure that the operator can still think and work normally after crossing time in an extremely harsh environment, and the other has external vision function, optical camouflage function, remote control function and so on.

From these proposed features, it can be seen that the risk of traveling through time is not only to successfully pass through the time storm zone, but also to deal with local intelligent creatures.

Lance and the others put the engine in their hands on the table, and then turned their heads to look at the several shells that Yan Cheng and Ji Feng had successfully manufactured in three days, and let out a burst of emotion.

"Yes, it's much better than it looks in the blueprints. ”

"Stop talking nonsense. Yan Ling walked over and took one of the engines that Lance and the others had placed on the table and took it into his hand. "My system coding has just been completed, and when the engine is installed, all the functional codes can be entered into each machine, so that our three-day task is roughly completed. After that, we will teach you how to activate the entire Time Travel Machine and how to operate it. After all, we are running out of time, and we will finally start tomorrow morning. ”

"Tomorrow morning?" Ji Feng reached out and grabbed his forehead, his expression slightly regretful. "The Great Star Tyrant Festival that Tears said will also start tomorrow morning, and I promised her to go over to participate in the bread eating competition, but it seems that she can't make it in time, but how should I explain it to her? ”

"A thousand needles, eldest sister, you really feel it!" Li Qiang was very heartless and laughed heartlessly.

Without waiting for Ji Feng to make a move, Li Xue immediately walked over and pressed him to the ground and beat him up, he actually dared to say that his sister, even if it was his own brother, he had to settle the account!

"Don't be so pessimistic, not necessarily. Ignoring Li Qiang, who was screaming, Lance, who was standing on Ji Feng's left hand, smiled, and then asked Li Xue. "I remember the bread eating contest was supposed to be scheduled for noon, right?"

"Well, the bread contest doesn't start until after three o'clock in the afternoon tomorrow. After listening to Lance's words, Li Xue stopped continuing to beat her own brother, and then nodded.

Although Li Xue has not been to the school for the past three days, as the school's physical education teacher, the schedule of the specific activity process of the Big Star Tyrant Festival has already been sent to her, and she already knew about it about a month ago, so Li Xue is so sure.

- By the way, Li Qiang, who was beaten, also knew.

With Li Xue's affirmation, Lance continued to explain under Ji Feng's puzzled expression. "Because it is the first day of the opening of the Great Star Festival, there will be a meeting ceremony every session in the morning, and the principals and vice principals of all schools will take turns to take the stage to give speeches for this year's Great Star Festival, and then there will be good news telegrams from major campuses, and several outstanding students on the level list will take the stage to give the "contestant oath". If I'm not mistaken, it seems that Mikoto Misaka, the "contestant's oath", was also named on stage. ”

"It doesn't matter, anyway, after all these tedious processes, the morning time is almost over, and the real activity can only start after lunch. Lance said as he walked slowly over to one of the time shuttles.

"We can currently achieve a ratio of 1 to 20 in the time traversal, you have spent 20 hours in the past and we will only pass 1 hour on our side, and you will have 100 hours to complete the task from 7 o'clock, which is a full 4 days. And you landed three days before the city of Villebain was razed to the ground, and even if you didn't find the culprit until the final destruction of the city, you can still have lunch with the tears when you come back. ”
