The idling test is a common method to test the service life of the engine, even if it is a luxury for the southern country that cannot mass-produce engines, but Jun Qianqian believes that these procedures are necessary.

The test site requirements are very low, as long as there is an empty room, a workbench, and the engine can be fixed.

All that remains is to arrange the personnel on duty to watch and see how long the engine will overheat, how efficient it will be after overheating, how long it will take to cool down after overheating, and how long it can rotate continuously before it is completely scrapped.

And the results of this test really got an engine with enough service life.

"Big brother has made a meritorious service!"

Jun Qianqian looked at the experimental data handed in, and smiled happily.

"Will you be able to use it for this year's autumn harvest?"

Daze finally breathed a sigh of relief, and when Jun Qianqian finally made it, their work really ended successfully.

"If the experiment goes well, it should be able to catch up, but why rush this, it's good to transport the ore first!"

The tractor is not an automatic harvester, even if it participates in the autumn harvest, it is of limited use, but the tractor is already an artifact for this era!

It's all over the place.

"Good!"

After a few months of study, the international students from Harrom Village and Stated City also finished their basic courses, and they did not have time to learn and consolidate slowly like the children in the south, but opened a small class to learn literacy and math in a surprise way.

After seeing the process of the autumn harvest, they also looked at the process of how the agricultural country functioned from beginning to end.

"I didn't see spring ploughing."

Linda is still regretting.

"Are you going to stay here until next year?"

According to the plan, the rest of the international students can go back after the autumn harvest, and they will take the copied books to study slowly, and if there is anything they don't understand, they can also ask when they communicate in the future.

"Then I'll go back in winter and come back in spring!"

At this time, the road connecting the two places has not been paved, this year's oil production is not high, the engine has not been built and there is no channel to consume, the asphalt is not produced much, and the road paving is like a patch.

But now there are often convoys coming and going between the two places.

In the past, the villagers would stop in the autumn when they had gathered enough food to survive, after all, even if there was a lot of food, such as fruits, would quickly rot in wet weather.

However, now it is different, and the villagers can use the food they pick more, store it according to the southern religion, or make it into jam, or dry it, and then send it to the southern country to exchange for food.

Grain is easier to store and filling, and this year's villagers are very energetic, and the mountains are going to be bald.

Linda: They brought back the seeds, and next year, they will start growing food.

"I hope you have a good harvest in the first year."

This winter, the city of Stater and the village of Harrom are going to officially discuss the merger, and Jun Qianqian will no longer keep Linda, and they also have a lot of things to do.

Whether it's building roads or building houses, the situation in the south is on the rise, expanding everywhere, waiting for construction everywhere, and the underground palace has begun to be cleaned up.

"I really didn't expect that there would be a vein so close to us."

Now that all the clans are a family, there is no need to keep it secret, when Xia Lan knew that there was a mining stronghold of the Purple Flower Tribe under their noses, she rolled her eyes in surprise at the same time.

Jun Qianqian is really a goblin!

"You can't put all your eggs in one basket."

How could such an important matter as mining and ironmaking rely on the White Rock tribe?

Jun Qianqian smiled.

However, cleaning up the mud of the underground palace this time allowed the people of the southern country to find an unexpected discovery.

"Found another pit?"

When the news came back to the capital Purple Flower, Jun Qianqian was very surprised.

"Didn't we find all the exits by then?"

Luo Ze was also surprised that they could still find other mines, and they had found every exit according to the map given by Jun Qianqian.

"Isn't the map complete?"

It's unexpected.

"Would you like to check it out?"

Luo Ze knew that news like the underground palace had something to do with the legend of the sacrificial platform, Jun Qianqian definitely wanted to go and see it in person, and it just so happened that they hadn't been very busy recently, so he could accompany her on a trip.

"I want to go!"

Jun Qianqian hadn't thought of going to see this step yet, but since Luo Ze asked, she thought for a second and immediately nodded.

"Then we'll leave tomorrow, and I'll accompany you over to have a look."

Luo Ze immediately arranged.

"Can I go along?"

Xia Lan watched the two of them decide, and hurriedly interjected.

"If you're busy, come here."

Jun Qianqian doesn't care.

"That's good!"

Ever since she knew about the existence of the dungeon, Xia Lan had always wanted to go and see it, but Jun Qianqian didn't want to stop her, but at that time, the dungeon was dirty and full of mud, and she suggested that Xia Lan wait until the dungeon was cleaned up before going.

It's not bad to stop by and see the new pit now, so you don't have to wait until the dungeon is cleared.

"There are still many doubts about the inheritance of the altar that have not been solved, and perhaps this is the piece of the puzzle that we have not been able to find."

Jun Qianqian recalled the colorful clothes that were dismantled into rags, and the message that the colorful clothes wanted to convey had not yet been cracked.

However, now Pello is almost unable to remember what the clothes used to look like.

"Let's go check it out first."

They have been busy in their country since the founding of the country, and at most they have walked in the direction of the village of Harom.

After the merger of the tribes, the existence of the bazaar was less necessary, and it was replaced by two commercial streets set up in the east and west of the outer city.

These shopping streets are open every day, and the customers have changed from the former tribe to the individual tribes, and everyone can go to the market at any time to buy vegetables or seasonings.

In addition to food, tools and some handicraft knick-knacks also began to become popular among the tribesmen.

The gradual independence of handicrafts from agriculture is a process of urbanization, in which Jun Qianqian has always focused on dealing with the affairs of the state, and has not been able to explore the mystery of the sacrificial platform.

"I always feel that if this secret is revealed, we will know something amazing."

Jun Qianqian is body has become an adult, and she looks no different from others, but her god stick physique seems to still be retained, and she has such a strong premonition at this time.

"To be able to set up so many clues and connect them into the truth of a story, just by looking at this intention, you can know that what you want to say must be very important."

Roze said.

No one would go to such lengths just to say something that wasn't a big deal.
