"We are not done yet," Lu Qingyang pointed at the roof, "The temperature drops quickly at night, we need to cover it with a 'quilt'! We need to quickly weave some thick curtains, cover it at night to keep it warm, and open it when the sun comes out during the day."

"Yes, yes, yes! Straw curtains are easy to make! There's plenty of grass in the team!"

"Wang Shun, bring a few people with you, and start braiding today! Make sure it's thick!"

Wang Shun explained, then turned around and asked, "Captain, you said that this shed... is now growing vegetables?"

"Bye!" Lu Qingyang nodded affirmatively, "Before the ground freezes, let's quickly loosen the soil, apply some base fertilizer, and sprinkle fast-growing seeds such as spinach, rapeseed, and quick vegetables! As long as there is enough sunlight and the temperature is maintained, the seedlings will definitely emerge quickly!"

He planned to take advantage of the chaos of tilling the soil to quietly mix in the high-efficiency organic fertilizer exchanged in the space to ensure the soil was fertile.

"Qingyang, this fertilizer looks very fine. What kind of fertilizer is it?" a member who was turning the soil asked curiously.

"Oh, this," Lu Qingyang's face changed color, he had already thought of an excuse, "I asked someone to get the experimental fertilizer from the Agricultural Technology Station, it's called 'humic acid fertilizer', it improves the soil and promotes root growth, the effect is better than soil fertilizer, why don't you give it a try!"

"A new thing from the agricultural technology station? That must be wrong!" When the members heard the words "experimental fertilizer" and "agricultural technology station", they were immediately in awe and worked even harder.

After the soil is turned over and the base fertilizer is buried, the seeds can be sown.

Lu Qingyang took out the seed bags he had prepared long ago - spinach, cold-resistant rapeseed, and quick-fried vegetables, all of which were excellent cold-resistant varieties cultivated in the space. Their germination rate and stress resistance far exceeded those of ordinary seeds of this era.

He demonstrated personally by spreading the seeds carefully and evenly on the prepared bed surface and then covering it with a thin layer of fine soil.

Lu Qingyang's gaze fell solemnly on the arched roof covered with thick plastic film.

The roof was smooth and beautiful under the sun, but his mind was filled with the heavy snowfall in the northeast.

The frame of the shed is made of old bamboo poles and wood. Although it looks solid now, once the snow is too thick...

"Lu Qingyang pointed at the roof, frowning slightly, "This shed looks good now, but I still have a knot in my heart."

"What's that?" Wang Shun asked happily.

"Snow!" Lu Qingyang spat out a word, his expression serious, "You know how heavy the snow is in our area. A heavy snowfall will collapse the roof. If the snow accumulates too much, I'm afraid it will crush the frame!"

"Oh no! But!" Wang Shun slapped his forehead and suddenly realized, "I was so happy that I forgot about this! If the snow gets too thick, the shed will definitely collapse! Qingyang, you are so thoughtful! Then... what should we do? At least let us climb up there to sweep the snow every day? That's too dangerous!"

He pointed at the top and sides of the arch frame and gestured, saying, "I've got an idea. We need to add a few 'spines' to this shed! Inside the shed, along the highest point of the arch, use solid wood or... well, it would be better to find a few thicker iron pipes to support a few top beams! Go straight from the ground to the highest point of the arch!"

There are galvanized steel pipes in his space, which are pressure-resistant and can be used for reinforcement.

As he spoke, he drew a diagram on the ground: "Just like building a house with pillars! These pillars will share most of the weight of the snow and protect our frame and plastic sheeting! The pillars should not be used too densely, just put one every two or three meters!"

"Beam support? What a good idea!" Uncle Lao Gen from the production team was an old carpenter and immediately understood the key point. "It's the same principle as the beams of our old house! With pillars supporting it, the snow will fall down and the structure will be scattered, making it easy to collapse!"

"Yes! That's the reason!" Lu Qingyang nodded. "By the way, we can make this arch steeper! Next time we build a new shed, bend the bamboo poles more sharply and make the roof more pointed, so that the snow will slide down more easily and accumulate more easily!"

"Good! The captain has a sharp mind!" Wang Shun's worried look disappeared.

"The mainstay is important! I'll find a way to get some iron pipes over here, and you guys can help reinforce them."

"Don't worry! Leave it to me!" Uncle Lao Gen accepted the order.

The snow problem has been solved tentatively.

A few days later, at night.

Lu Qingyang held a flashlight, quietly lifted a corner of the straw curtain, and went into the shed.

A moist scent mixed with the scent of earth blew towards me.

He squatted down and shone the flashlight beam on the moist soil.

I saw one, two, countless dots on the brown soil surface... the tender green, vigorous bud tips stubbornly broke through the thin soil layer and timidly poked their heads out!

Now that it was autumn, they should be able to put up a few more sheds before the New Year.

As autumn deepens, the colors of the Greater Khingan Range become more intense.

Some members are still transporting the limestone layers that were previously discovered in the mountain.

"Hey yo! Hey yo!" Amid the shouts, the iron pickaxe hit the gray-white rock, making a dull sound, and broken stones and powder fell down.

Sun Xiangqian, who was in charge of swinging the sledgehammer, felt as if the tip of the pickaxe had hit a particularly soft spot, as hard as rock, with each blow.

He let out an "eh", stopped, and used a pickaxe to dig away the rubble.

"Xiang Qian, what's wrong? Did you dig up a rat's nest?" Er Gouzi, who was pushing a cart next to them, joked.

Sun Xiangqian ignored him and fiddled with his brows.

A light warm breeze with a strange smell suddenly blew out from the soft gap and hit his face.

"Wow! What's that smell?"

Sun Xiangqian fanned the room subconsciously. The smell was a bit pungent, with a bit of... sulfur and eggs?

He moved closer to the bowl-sized gap that had been chiseled out, and a more obvious warm and moist air gushed out. There seemed to be a faint "gurgling" sound coming from deep in the gap.

"That's right! The bottom of this stone seems to be solid!" Sun Xiangqian called to Wang Dagang beside him, "Captain Wang, you are very knowledgeable, come and take a look! The air coming out of this excavation is very hot! There is also a strange smell!"

Captain Wang put down the steel chisel in his pocket, came over, and probed the gap with his pocket. His eyes widened immediately: "Wow! It's really warm!"

He sniffed the steamy wind carefully, and his eyes suddenly lit up: "Smell of sulfur! This... Is there warm water underneath?!"
