Qiao Xuejun followed the same method and pried off the remaining relatively small stones.
This is originally a downward slope, so once the stone is pried open, it will easily roll down. With a rope to pull it, it will not roll around but will stop in front of a big tree in the direction it is heading.
There was still a stone half a person's height left, which might weigh five or six hundred kilograms.
Originally I thought that after prying away the small pieces, I might not need to pry the big ones to get in, but Qiao Xuejun actually tried it and couldn't get in, it was almost there.
Shen Xingtang was really ruthless. He had to pry it open.
But now the hole was half exposed. If she just pried the big rock a little more, she could get into the hole without having to pry it all the way down.
Qiao Xuejun sat down and took a rest. She felt exhausted after prying those three stones.
Qiao Xuejun took out the water bottle she brought with her from her backpack and took a sip of the warm water.
The thermal insulation effect of this kettle was very good before, but now the weather is cold, and the water in it is only lukewarm during the half day I was out.
System: "Host, this stone looks difficult to pry open. How about waiting for Zhao Xian to be free to help you?"
This stone was several times larger and heavier than the previous ones. Qiao Xuejun had a hard time prying the previous ones, and this one was even harder.
Moreover, the system didn’t understand. It was obvious that crops could be grown in the shelter, so why did Qiao Xuejun insist on looking for new plants outside?
The system thought about it and asked directly.
Qiao Xuejun took another sip of water, calmly covered the kettle, and pulled up the mask again: "The world outside is vast, why only rely on the fifteen acres of land in the shelter?"
Even if the land of the shelter could continue to expand, she would not give up hope of finding suitable land for farming outside. She never gave up.
What if one day the system disappears or becomes paralyzed, then won’t she just be waiting to die?
She didn't want to wait to die.
Since there is a chance to survive, of course we must seize it.
The system complained: "I won't be paralyzed."
Qiao Xuejun: “I hope so.”
After resting enough, she stood up again and tried to pry the last boulder. It was impossible to pry it with the previous method. 300 kilograms was already the limit.
We have to think of another way.
Qiao Xuejun untied the rope from the small stone below and tied it to the steel rod. This completely different approach from before made the system puzzled: "Isn't the pulley principle used anymore?"
Qiao Xuejun: "As we all know, the longer the stick, the less effort it takes. A 4-meter-long stick can pry up an object weighing 5,000 kilograms."
"But in reality, what matters is not the length of the stick, but the distance from the fulcrum where the force is applied."
Qiao Xuejun held the rope and found another tree. The tree was almost in the same direction as the stick, but because it was a slope, it was much lower than the height of the stick. She tied the rope to the tree, and the angle between the rope and the stick was 90°.
The stick in her hand was only 1.4 meters long, so she could only pry 300 kilograms. But the rope could extend the force point. The distance was at least three meters, so she could pry 500 kilograms.
After she finished speaking, she pulled the rope down hard!
“Click!”
Under the force exerted here, the half-man-high stone was pried forward by the steel rod and rolled forward a distance of thirty centimeters.
As the big rock moved away, the steel pipe was pulled out by the rope.
Qiao Xuejun quickly retracted her strength, thus avoiding falling on her butt like before.
The system was very happy: "Host, it really worked! You are so awesome!"
Thirty centimeters is more than enough to get into the hole.
Qiao Xuejun laughed: "Don't you have this solution in your database? Did you have some kind of flattery system before?"
System: "I have it in my database, but it's all theoretical. It's difficult to operate in practice. No host I know of has ever done this before."
Qiao Xuejun: "Because no one is trying to trip them up, and no one is blocking the road with big rocks, they don't need to do this."
Thinking of Shen Xingtang makes me angry.
Qiao Xuejun put the rope back together and held it in her hand. Although she moved the stones, it was not easy. Even with gloves on, her palms were still rubbed and hurting from the excessive force.
She walked to the entrance of the cave and looked inside.
There was no light inside, it was pitch black, but Qiao Xuejun could hear the sound of water dripping, "patter, patter".
Qiao Xuejun took out a flashlight from her side bag and shone it inside.
The light illuminated the interior, and Qiao Xuejun opened her eyes wide. What is this...?
A lush purple covered the entire cave, and the small purple flowers swayed gently with the wind blowing in from the cave entrance.
Qiao Xuejun opened her eyes wide.
Because according to Ren Wangwang's description, there is only one plant here, and it is gray.
Qiao Xuejun thought that the man might be standing at the entrance of the cave, and it was dark so she couldn't see clearly.
This is a very eye-catching dark purple color, especially in such a large area.
After making sure there were no mutant creatures lurking, Qiao Xuejun went in. She took out a notebook and a pen from her backpack, walked to Zihua and squatted down first.
This herb is tall, about 120 cm tall, and blooms blue-purple flowers with butterfly-shaped petals.
Qiao Xuejun clamped the flashlight under her chin and opened the notebook in her hand. She first drew the appearance of the flower, and then wrote down the characteristics of the plant she observed next to it.
"…trifoliate, oblong leaves…covered with pubescent hairs…"
She paused for a moment and said, "It looks more like Cassia tora."
Cassia tora can even bloom in the Arctic and can tolerate temperatures as low as -20 degrees Celsius.
There are many plants that can withstand the cold in winter, which is why Qiao Xuejun has been looking for them. Common ones include wintersweet, which can bloom even at minus 15 degrees Celsius. If it had not been killed by the extremely high temperature in the early stage, Hongmei Mountain would already be filled with the fragrance of plum blossoms.
Roses and tulips can survive at minus 35 degrees Celsius.
However, the plant in front of us is a little different from the purple-flowered Cassia. The purple-flowered Cassia is a low herb, generally between 8 cm and 30 cm, but this flower is 120 cm tall, which is considered a tall herb.
"Teacher Qiao!"
Qiao Xuejun was writing down things in her notebook when she heard shouting from outside the cave.
It seems to be Ren Wangwang’s voice?
Qiao Xuejun was about to turn her head to look, but found that she couldn't. She had been holding the flashlight under her chin for a long time, and she had been in the same position for a long time. The cave was damp and cold, and her body was stiff.
