After absorbing the two hills, Chizhu recalled the palm of his hand, Jian Ning opened his eyes wide and looked closer, absorbing hundreds of trees Chizhu did not seem to have any change, and it may not be observable with the naked eye.

Red beads can ingest anything that can be burned and release heat, whether liquid, solid, gas, or wood.

Coal is the best.

Of course, Jian Ning knew that the release energy of oil was as high as twice that of coal, and although he had not collected oil in his previous life, the knowledge he had learned was stored in his mind.

The calorific value of coal is 29306 kJ/kg.

The calorific value of oil is 41868 kJ/kg.

If she hadn't discovered Chizhu's treasure in the eleventh year, she would definitely not have died in vain, because as Chizhu's energy increased, her body would change and become stronger!

It's a pity that at that time, we could only collect some leftovers of inferior energy, and the world's resources were almost exhausted.

It's not that she didn't think about going to the sea, to the mountains...... Explore oil and coal that humans have never discovered to be extracted.

But the Chizhu people can't enter, and they can't make a long journey to sail in the harsh environment, and the weather during that period is completely irregular, and the violent storm and snow are coming, and the fist-sized hail is smashed, and there is no warning at all, and there is no logic at all.

I can't get that much food for people to trek into.

Away from the base, there is a 99.9% chance of being folded outside.

Jian Ning retracted his mind and tried to take something from the red bead, absorbing a little energy in case it was done.

Well~~~ I can't take it out!! I still want to get a steel knife out to cut down trees, and the dagger given by my uncle is also placed inside, as well as the relics of my parents.

Later, he collected a lot of materials that were abandoned by mankind in the last days.

Countless.

The quantity is large, the range is wide, and the variety is complete.

For example, messy electrical appliances, steel bars, iron lumps in suburban factories, food machinery production lines, and discarded instruments in hospitals......

Porcelain, glass, steel shelves, various tools......

Cars in underground garages, off-road, sports cars, large trucks, containers...... The whole nine yards.

Airplanes, ships, and even trains...... Varied.

People go to the tableware, kitchen utensils, water pipes, safes, and furniture that have been stripped of the wooden boards of empty houses...... The toilet in the bathroom is included.

Everything that can't be eaten or burned, others don't want it, so Jian Ning is not welcome, and all of them are in the red beads.

From the outside, the inside of the red bead is a round shape, the ground is all the same red rock, the temperature inside is suitable, there is no mountain and no water, and the endless emptiness.

The boss inside is the boss, anyway, her consciousness has been floating in it for a whole day and she hasn't explored the edge, she didn't give up and moved a lot of soil to throw it in, sowed a few particularly precious grain and vegetable seeds from that period, and carefully watered and fertilized.

Sadly, the soil that was moved in merged with the ground the next day, turning into a lump of red rock, and the seeds scattered were intact in the rock.

Jian Ning was puzzled, why?

The electrical appliances that come in, how can those messy things be good?

Discrimination?!

Now, except for the caloric substances that the red beads can absorb, the things that were stored earlier can neither be taken out nor put in.

Lack of energy to turn on.

The top priority is to find a few coal mines for Chizhu to absorb, just wait for Jian Zhenjun to return home, and set off as soon as the spring ploughing is over.

Jian Ning was very satisfied with the era he had returned, when the country had not yet begun to export coal, the economy had not entered a period of rapid development, and the underground resources were abundant.

Red beads do not need to be manually mined for heat intake, the way is similar to absorbing trees, and throwing it into it is extremely convenient, as long as you hold a map and find the source of minerals, the world's coal mines are in hand.

After absorbing the heat, Chizhu spontaneously returned to the nest, Jian Ning always felt that the baby had an independent consciousness, because the pile of broken copper and iron that was stored in it before would be automatically classified, and whatever kind of food was put in, it would be taken out, and it would not deteriorate after a long time.

At the beginning, Jian Ning collected some books, and at that time she was worried that the books could be converted into heat when they were ignited, and the red beads would not be absorbed.

As it turns out, no.

Not only will it not be neatly arranged for detailed classification, but it is very humane.

I just don't know why it doesn't want to see mud, or maybe it lacks some substances and can't grow food, so it simply dries the mud into rocks, which is equivalent to a hint.

Remind her not to do something that she doesn't have, it's useless!

The above is just made up by Jian Ning's own brain, and the truth remains to be verified.

The next day, Jian Ning went up the mountain according to yesterday's steps, picked up manure, stirred the manure tank, cut down trees, and dragged trees to pile up the hill for Chizhu to absorb the heat.

Today there is one more step, digging a manure tank.

Sugar cane should be planted in the mouth of the gorge, and a manure tank is definitely not enough.

The stump left on the ground, planning to wait for her father to return home, take the third sister and her father to dig it together, the stump is no better than cutting down a tree, and it is particularly troublesome to clean up.

They also pick up rocks, hoe weeds, plough the ground, apply fertilizer, plant seeds, and water ...... These are delicate and time-consuming tasks, not something that can be solved by brute force.

plus a few acres of land in the thorn forest, a total of more than a dozen acres.

It takes nearly three hours to go up and down the mountain every day, and she does it alone, and it is estimated that she will not be able to catch up with the pace of spring ploughing.

The plan of the year lies in the spring, and before the spring ploughing comes, it is necessary to reclaim all the more than a dozen acres of land.

On the twentieth day of the first month, the side house and the straw shed were completed.

The partial house is a brick and mud mixed house, using the main house has not been used up of materials, stronger than those old mud houses, and the appearance is also a lot higher, fortunately Jian Ning brushed the old house with lime putty, and the yard was paved with stone slabs, otherwise the side house stood next to it and it looked very abrupt.

While their family was repairing the yard, the Xu family was also in full swing to build a new tiled house.

It is said that there is an endless stream of people who go to help, and in just ten days, a small half of them have risen.

Jian Ning listened to the helper in their house, and didn't bother to pay attention.

In the past few days, every time Jian Ning went down the mountain, he would dig a basket full of thorn roots, and when he came back, he planted a circle of dense turns outside the fence wall, and when it grew up, it was a solid defensive wall.

Deliberately selected varieties with sharp thorns, the kind of thorns can grow more than two meters high, and the thorns growing on the branches are as long as a person's little finger, sharp and hard.

In the thorn bushes, a few handfuls of 'Xanthus' seeds are sprinkled, Xanthium is a kind of traditional Chinese medicine, the fruit bears a hedgehog shape, the surface is covered with dense small thorns, sticky and stinging, the fruit is ripe and falls to the ground, and the mice dare not drill.

The twenty-first day of the first month.

The wind is gentle and the sun is blowing, and the breeze is smooth.

After more than 20 days of recuperation, Jiang Yihua's external injuries have fully recovered, and Dr. Song came to remove the splint a few days ago, and now he can walk slowly on the ground a few steps, and he can basically solve the physiological problems by himself.
