Su Heng took out these three items from the mail, and took this small firearm in his hand and looked at it carefully.

The whole body of the firearm is made of forged iron and hard and strong high-grade wood, and it is about the length of an arm.

[Homemade Homemade Shotgun]

[Quality: Intermediate]

[Grade: Advanced]

[Function: Using gunpowder as an energy source, it can launch shotgun/beam projectiles of the corresponding caliber]

[Evaluation: The design of the parallel double-barrel makes it have strong firepower, extremely high reaction ability, and absolute suppressing power at close range, suitable for sudden battles such as jungle/town encounters/ambushes and other complex terrains]

"This work is a bit good!"

Su Heng has to admit that after Li Sike obtained the test bench, the efficiency has been greatly improved, and even the workmanship has become more refined.

What Li Sike did before was either the lowest level or the lower level.

This time, the complicated firearm was made into an intermediate quality by him, which is gratifying.

【mission completed! 】

[Congratulations for getting: Doomsday Honor 300 points]

[Congratulations on getting: Advanced Golden Treasure Chest! 】

[Is it open? 】

"Advanced golden treasure chest?"

"open!"

[Congratulations on getting: High-grade plastic*3, high-grade iron block*7, high-grade steel plate*4, explosion-proof glass*1, lead-acid battery*1]

"Battery!"

Su Heng checked its entry attributes for the first time.

[Lead-acid lithium battery]

[Quality: Top class]

[Grade: Advanced]

[Function: It can directly convert chemical energy into electrical energy, the total conversion rate is more than 95%, the electricity storage is 150kW h, and it can be recharged in various ways]

[Evaluation: Reliable work, the first step into the electrical age! ]

When Su Heng saw this box of batteries, his eyes gleamed greedily.

At 150 kWh, the battery capacity of Hora's flagship electric car is 1/2 larger!

"Is it finally time to return to the age of electricity?"

"I originally thought about putting it on a mountain bike and upgrading it to an electric bike!"

"Such a large capacity can fully support my electricity use in the shelter!"

Li Sike sent Su Heng a private message.

Li Sike: "Mr. Su Heng, the item has already been mailed, please check it carefully."

Su Heng: "I have already received it."

Su Heng: "Dr. Li, since you are majoring in physics, may I ask how much you know about electricity?"

To restore the power era, the support of science and technology is indispensable.

Li Sike: "Well... how should I explain it to you?"

Li Sike: "I know a little bit."

Su Heng: "?"

Do you know a little bit?

Li Sike: "Classical mechanics, theoretical mechanics, electromagnetism, electrodynamics, thermodynamics, quantum mechanics, atomic separation physics, I know a little bit."

Li Sike: "I have been interested in physics since I was a child, and I have a double doctorate."

Su Heng: "..."

A little too modest.

Is this called a little understanding?

Su Heng: "Dr. Li, this is the case. Since you have research on electrodynamics, if I provide raw materials, can you make batteries or motors?"

Su Heng: "The battery doesn't need to be too big, maybe it's a battery like an electric car."

Li Sike: "The battery is not complicated, but the motor is a little troublesome, but since Mr. Su Heng needs it, I will try my best to do it."

Su Heng: "Yes. In addition, Dr. Li, I would like to trouble you again. Go outside to collect some polluted water and send it to my mailbox."

Li Sike: "Okay, Mr. Su Heng, do you want to purify the polluted water again? No problem, how much do you need?"

Su Heng: "Uh...about 30L is enough."

Li Sike: "Mr. Su Heng, can you take the liberty to ask, what is your success rate in purifying polluted water?"

Li Sike: "If 30L of polluted water is purified to drinkable pure water, will the loss of the entire chemical process be very high?"

Li Sike: "After purification, how much is left? 5L? 3L? 1L?"

Li Sike was very cautious and did not ask Su Heng how to purify, but wanted to know his success rate.

Su Heng did not purify according to scientific methods!

He couldn't say why.

He just replied "almost" and then perfunctory.

After finishing the conversation, Su Heng started to upgrade the food processor.

"I've been thinking about it for several days, and finally I can upgrade!"

Su Heng currently has 2010 Doomsday Honor in his hand. Using the previous blueprint, he just met the upgrade conditions.

[Exquisite food processor design drawings]

[Required materials: Old Food Processor 1/1, Doomsday Honor Point 2010/2000]

"Confirm the upgrade!"

After scanning the old food processor with the golden code, a brand new food processor appeared in front of Su Heng.

【update completed】

[Current Doomsday Honor Remaining: 10 points]

"Huh? The area has grown a lot!"

The original one-person-high food processor has reached a height of 2 meters 2 and a width of almost 2 meters, which covers a larger area.

"Ow~"

Luo Luo, who was on the side, saw that the food processor suddenly became bigger, and couldn't help being startled. She stretched out her claws and slapped the machine.

"Why? Don't break it for me."

[Fine Food Processor]

[Quality: Superior]

[Grade: Advanced]

[Function: 100% of mutant food becomes ordinary food, 10% becomes excellent food, 2% becomes super food]

[Ordinary food has a 50% chance of becoming excellent food, and a 3% chance of special food]

[Excellent food 14% chance to become super food]

[All processing modes 2~4 times crit]

[Evaluation: Only in the world, a survival artifact in the apocalypse! ]

"The probability hasn't changed much~lightnovelpub.net~ The most useful thing is 2~4 times the crit!"

"In addition to the probability, this upgrade also increases the capacity of the food processor. Water can be put into 8L, and food can be put into 30kg."

"If Dr. Li knew that I purify polluted water, not only will it not be consumed, but it will be multiplied. I'm afraid it will collapse the science he believes in."

Li Sike soon mailed 38L of polluted water.

"Try it first."

Su Heng poured 8000ml of polluted water.

Select 【Mutation Mode】

Pull down the handle.

"start up!"

Su Heng heard the sound of the operation of the new processing machine.

From the previous "buzzing buzzing", it has become a pleasant "buling, buling, buling~"

"My dear, even the voice has changed?"

【Processing completed】

[Exquisite food processor: 3 times the critical strike! 】

【Get: 24L pure water】

[Today's Remaining Times: 4/5]

! ! !

"try again!"

Su Heng poured 8000ml of polluted water for the second time.

start up!

"Bling, Bling, Bling~"

【Processing completed】

[Exquisite food processor: 4 times the critical strike! 】

【Get: 32L pure water】

[Today's Remaining Times: 3/5]

"I lost it and processed 56L of pure water twice?"

"Compared to the previous efficiency, it is a geometric improvement!"

"Critical attack mode is so terrifying!"

Su Heng glanced at the corpses in the warehouse that hadn't had time to be processed, and thought about it with fear.

"On the 10th day of the apocalypse, I can finally take a hot bath!"
