Looking at the mountain of ores, Chen Zheng couldn't help rolling his eyes. He forgot to tell the man with glasses about the earthen blast furnace.

"Come with me." Chen Zheng came to his bronze smelting scene with a man and a girl in glasses.

After the last copper ore was refined, Chen Zheng had already cleaned up the slag and repaired the inside of the furnace. Now, just by refilling charcoal and ore, copper water can be refined.

"Wow... this is really rare... you made it?" The girl exclaimed at the towering mud blast furnace, looking up and down around it.

Chen Zheng even suspected that if she brought her cell phone, she might have taken it out and taken a photo and posted it on WeChat Moments.

"…Is this?" The man in glasses didn't know what it was for.

"The blast furnace is a bit simple, although it is a bit simple," Chen Zheng explained.

"blast furnace?"

"You never use this thing to smelter metal?" Chen Zheng asked with his head tilted.

"Yeah." The man in glasses nodded honestly, "I've never seen it before."

Chen Zheng couldn't help but roll his eyes and had to talk about how to smel the copper.

"You mean, just put charcoal and ore and keep blowing... you can get copper!?"

When Chen Zheng finished speaking, the girl turned over and interrupted.

"It's hard to believe... Such a simple thing can smel metal..." When the girl saw Chen Zheng nodding, she became more interested in the blast furnace.

On the other side, the man with glasses fell into deep thought.

"…Superheated carbon reduces metal oxides, and after the metal melts, seeps through the charcoal layer and filters out most of the impurities... The principle is very simple, but… the person who invents this kind of blast furnace is simply a genius!"

The man in glasses exclaimed.

"Under such primitive conditions, even gravity is used, this idea is simply... simply... incredible!"

"As for it?" Chen Zheng sighed, pointed to the carbonization pool not far away and said, "Come on, let's fill the carbonization pool first."

Time slips away quietly in the busyness.

With a few people helping, especially the existence of BT-7274, the "super strong laborer", Chen Zheng and his team's progress suddenly became faster. When they were surviving alone, they had to do a lot of work by themselves, wasting time and physical strength but had to do it. Now, these problems with the crude benzene make Chen Zheng just say it.

When night fell, Chen Zheng stretched his waist and ran to the "refrigerator" area to pick up a thick piece of fish and brought it back - he couldn't stand the alien food that seemed to be rice porridge and paper.

"what are you up to?"

Just as Chen Zheng was packing up the fish, a female voice came from behind.

"Cooking." Chen Zheng said without looking back, putting the fish on the wooden stick in his hand, brushing the sea salt and putting it next to the fire.

"This is... what animal's meat? Looking at the slightly red fish meat, the girl couldn't help but frown.

"Fish." Chen Zheng said neither salty nor lightly.

"You actually eat something of unknown origin and aren't afraid of contagious parasites?"

"...Do you want to try it?" Chen Zheng raised his eyebrows.

"I don't want it! I don't eat such corpses of unknown origin." The girl shook her head, "It's unhygienic and unhealthy. Why do you have to kill those animals for meat? You..."

Bar, bar, bar, bar,...

Chen Zheng ignored her and carefully flipped the fish, brushing some salt water from time to time to avoid the batter.

The tongue of fire kept licking the fish meat fibers, and the white fish meat gradually turned yellow... In a short while, the fragrance of the fish meat floated out.

"...What a strange habit. Do you earthlings eat like this?" The girl still asked, "Lan Yin also used animal corpses to fill his stomach when he came to Earth. He really got back to life... Guru..."

"Sher—"

The fat from the fish meat dripped into the fire, and a strange fragrance filled the girl's nose, making her swallow unconsciously.

"Huh? Strange..." The girl was stunned.

Chen Zheng took off the grilled fish meat fire that was oily, tore off a small piece and handed it to the girl's mouth.

"Try it?" Chen Zheng raised his eyebrows.

The girl looked at the fish meat that was steaming, with a burnt appearance, tender white inside, and still steaming water, and said in a bad mouth: "What's the best for this backward and savage diet... Um!"

She opened her eyes wide and looked at Chen Zheng in disbelief.

Before she could finish her words, Chen Zheng stuffed the piece of fish into her mouth. When her fingers touched her lips, the soft touch made Chen Zheng's fingers numb as if they were over-electric.

"Cough cough." Chen Zheng coughed a few times and covered it up.

"Wuhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

The girl's cheeks were bulging high, and her cheeks began to squirm like a hamster... After a while, she heard a "gurgle" sound, and the large piece of fish was swallowed into her stomach.

"How is it?" Chen Zheng had a faint smile on his face.

"Hey! Why are you laughing at?" The girl's old face turned red.

"It's nothing, I just want to ask... Is this kind of barbaric and backward thing delicious?" Chen Zheng asked maliciously.

"Not delicious!" The girl stared at her eyes angrily and snatched the fish steak in Chen Zheng's hand, "And you even forced me to give it to me! You are punished not to eat!"

"Acknowledge the punishment." Chen Zheng raised his hands like a surrender, and then focused on roasting a fish steak.

The girl glanced at Chen Zheng sneakily, and quietly tore off a piece of fish and threw it into her mouth while he was not paying attention.

"Sha..."

The fish is a little hot, and the girl instinctively sucks the air to increase ventilation to reduce the burden on her mouth.

After Chen Zheng brushed a layer of salt water on the fish, he suddenly felt a sound around him. When he turned around, he met the girl with a bulging cheek like a hamster.

"Mmmmm (what are you worried about)!" the girl glared at him.

"Is it delicious?" Chen Zheng asked with a smile.

"Gulu (swallow)...not delicious!"

"Ha ha ha ha……"

"What are you laughing at! Don't laugh!"

...

It's already late at night.

The lights are still on in the big tent.

The five men and five others were busy busying themselves. On the wooden board next to them, the mass and energy formula written by the charcoal pen was placed in the most conspicuous position in the entire tent.

"...Okay, follow the formula and adjust the next parameter... Are you ready?"

The man with glasses sounded in the tent.

"It's ready." Everyone replied.

"Huh..." The man in glasses took a deep breath, "Then let's... start!"

As he said that, he pressed the main switch.

Suddenly, the data stream that could not be seen clearly by the naked eye began to jump wildly on the display screen.

Chen Zheng didn't expect, nor did the man in glasses imagine that by chance, a formula containing only 5 letters of symbols meant to humans, the earth, and even to all civilizations.

The first collision between Earth civilization and alien civilizations created dazzling sparks.
