The charcoal pen kept sliding on the wooden board, making a pleasant rustling sound. As Chen Zheng's pen tip moved, a neat and clean design drawing appeared on the paper... on the board.

The sunlight outside the window shone on Chen Zheng’s serious face, and the outline of the shadow outlined his facial features even deeper.

"What are you doing?" a female voice rang.

"...design drawing..." Chen Zheng responded casually without even raising his head.

"Is the zero crystal powder I want ready?" The girl walked to Chen Zheng, put a pot of snot-shaped things next to the table, and looked up and down with interest.

"What is this?" the girl asked curiously with her long golden hair lifted up behind her ears.

"The cooling system of the track..." After Chen Zheng finished drawing the last stroke, he placed the charcoal pen next to him, wiped his hands with the hay beside him, and his eyes finally shifted from the drawing to the girl.

"...How is their research?" Chen Zheng asked with his head raised.

"There is no result." The girl shook her head slightly, and her long golden hair turned with her movements like a waterfall. "Don't have too much hope. The zero-energy furnace is not something that ordinary people can study clearly. Even at the heyday of the Blue Gold Empire, there are no more than one person who can participate in the research and improvement of the zero-energy furnace."

"Well, I didn't have any hope at all." Chen Zheng smiled, "I just want to absorb some advanced design concepts and use them on our own functional systems."

"First eat something, then bring the Zero Crystal Powder with me. I want to add fuel to the Zero Neng Furnace, you can also watch it." The girl said.

"Yeah." Chen Zheng said as he brought the bowl brought by the girl...

"Uh... are you sure this thing can be eaten?"

Looking at the "snot" in the bowl, Chen Zheng hesitated.

"What? Haven't you eaten fermented synthetic food?" The girl laughed, "In this regard, you are the same as that guy Lan Yin."

"No, I mean... forget it." Chen Zheng sighed.

This kind of snot-shaped food is the semi-finished product just produced by the C-type camp truck. It originally needed to be compressed into pieces, but the supporting molds and hot presses were destroyed in the battle. Chen Zheng and others are busy preparing for the battle and have no time to create another set, so they can only use this semi-finished product to replace it.

As a citizen of the foodie empire, this kind of thing is really not easy to eat, especially after knowing that it is made of leaves, bark and smelly seaweed, I feel very sad just by feeling.

"Ahhhh." He suppressed the discomfort in his heart, dug a spoonful and put it in his mouth.

"Huh?" Chen Zheng was stunned.

This thing is really not bad.

If you want to describe the taste, it is probably the rice porridge that adds a small amount of sugar, a small amount of salt, a large amount of starch, a small amount of paper and seaweed.

It is a little sweet, with a hint of wood fiber and seaweed flavor, but it is not obvious. It should be that there is still some unsaccharified cellulose mixed in it.

“It’s hard to eat?”

"Yes." Chen Zheng nodded.

If he had let him eat this thing every time, he would rather starve to death.

"You are so straightforward and cute..." The girl shook her head with a smile.

After a painful meal, Chen Zheng brought the design drawings to a large tent not far from the wooden house.

Here, the five-piece male glasses are busy busy around a cylindrical object.

"Have the energy system not been completed yet?" Chen Zheng asked.

"Uh... we haven't figured out how it works yet, and we can't even use the energy it outputs." The man in glasses told the truth.

"Not electricity?" Chen Zheng was not surprised that he could not use the zero-energy furnace. What surprised him was that the energy it output was not electricity!

"That is a very strange energy, both gentle and violent. It can output slowly and slowly with a long flow of water, or consume all the zero crystals stored in the entire zero energy furnace in an instant! Those who have developed this zero energy furnace must be a super genius!"

The man in glasses admired the designer he had never met before.

"Then what is he outputting? Light? Heat?" Chen Zheng frowned.

"...I don't know...but it's definitely not a conventional energy source." The man in glasses was embarrassed and spread his hands.

"Then... put the energy supply device first, you can take a look at this design drawing." Chen Zheng handed him the wooden board.

"A good idea is to bury the thermoelectric converter into the track, which can convert the heat energy during emission into electricity, which not only cools the track and increases energy... But I am bluntly... we cannot make thermoelectric converters now."

"The one you're reading is an advanced version. Look down, there is a water-cooled version below." Chen Zheng reminded.

"...The water sleeve and heat sink are double cooling, and even the steam outlet that releases pressure is thought out, and the steam emitted can be used to reduce the recoil...a near-perfect design."

The man in glasses pushed the eyes on the bridge of his nose, nodded at Chen Zheng admiringly, and then couldn't wait to input the design into the instrument, and then started the calculation for 5 minutes.

Soon, the result came out.

"Depending on your design, the new track can have a maximum temperature of not exceeding 1,000 degrees when launching copper projectiles, and the temperature will not exceeding 800 degrees when launching aluminum stent dehulling armor-piercing projectiles."

"800 degrees..." Chen Zheng nodded.

If the actual data can match the paper data, then Chen Zheng’s electromagnetic track version 2.0 can be close to practical. And the biggest problem that troubles him now is the energy source.

Now it seems that the zero-energy furnace used on the BT-7274 is no longer expected.

In this way, the energy supply system will be very bulky, huge, and difficult to charge quickly.

"It seems that we can only create a single-spread version." Chen Zheng made a decision without thinking for too long.

Even if each electromagnetic railgun can only threaten the butcher driving the Red Lotus once, it is better than nothing. At least it will more or less increase the girl's chance of winning.

At present, Chen Zheng and the others have not many ways to threaten the red robot, among which only the "virtual light cannon" system equipped on the BT-7274 is confident of killing it.

However, every time a virtual light cannon is fired, it consumes three-quarters of the energy of a zero-energy furnace. Unfortunately, the other three zero-energy furnaces on BT were thrown out by the girl as bombs. However, the black sails were blown away by the person who was killed for half a year, but this also left the girl with only one chance to kill the combination of Honglian and the butcher.

Considering Honglian's agility, the fault tolerance rate is too low if there is only one chance. Chen Zheng cannot pin all his hopes on the girl's failure to miss it.
