The first geological exploration, although the time was a little shorter, was also a perfect end.

According to the preliminary inference, this spirit stone mine is very, very, very large!

How big is that?

Let's put it this way, Su Delin's spirit stone mine was dug for almost 3 months, and a total of 120,000 spirit stones were dug up.

And this mine, according to Zuo Zhou, is like a sky full of stars, vast and endless, and there is no edge in sight.

The place surveyed today has almost 3~50,000 spirit stones, and such a place only accounts for one-tenth at most.

The minimum guarantee can produce 300,000 spirit stones.

However, there is one thing that is not good, the distribution of spirit stones in this spirit stone mine, that is, the density, is relatively small. Su Delin's mine, the most dense place, can dig out dozens of spirit stones per cubic meter, and this mine, the highest density found in Zuozhou, there are only a few spirit stones per cubic meter.

Tang Ranran, who was idle, was sent by Xie Xingyun, returned to the First Military District, and went through a security check at the door of the protective shield, and at Tang Ranran's request, Xie Xingyun took her to the artificial vegetable field in the military area.

Tang Ranran began to plant vegetables, and Xie Xingyun once again became a guard, busy coordinating the picking, counting, boxing and other work.

Lower, medium, top, and even the best.

She should have developed more special abilities!

At the end of the exploration work, the self-taught Zuo Zhou drew a three-dimensional energy stone distribution map, although not professional, but also presentable.

2 trillion, when this small goal is to be exchanged for a low purification value, the unit price is low, and this amount will come up.

Tang Ranran is definitely going to keep him here to be in charge of the mining work.

When he was underground just now, after two hours of exploration, Zuo Zhou, "Boss, there is a particularly strong energy mass!" ”

Of course, Zuo Zhou also stayed here to verify the location of the energy stone, and beware of deviations in the mining process, and the more he dug to other places.

Moreover, in the same way, the vast majority of them are low-grade spirit stones.

Of course, there is no urgency in this matter, the most important thing at the moment is the spirit stone mine.

Relying on his ability, after completing the ore map, Tang Ranran shared the relevant data with Xie Yan, and then discussed the mining work.

In the next few days, Tang Ranran and the two of them have been conducting underground survey work.

The entire Lingmai Mine, like a real dragon, is long and serpentine, with a length of about 1,200 meters and a cross-section of 200 square meters.

With Zuo Zhou's cheat, Tang Ranran didn't even need to open the blind box to know what was in the box.

Time is limited, Tang Ranran decided to solve it quickly.

After the basic discussion, there is nothing to do at this ore site.

That is, a whole 240,000 cubic meters of stone to be dug up!

Especially at the edges of the mine, it takes almost a few cubic meters to produce such a spirit stone.

Because he was not a handsome guy, Tang Ranran didn't dump him, and politely rejected the friend application of the middle-aged quartermaster minister.

Because the news that 'Tang Xuan can use special energy stones including Xingzuan raw ore to grow vegetables' has been secretly released in a small area, Tang Ranran is unscrupulous in planting vegetables, and is ready to catalyze 500 tons a day.

One piece of top grade is equal to 10 pieces of medium grade.

Although Tang Ranran was worried about a lot of spirit stones, she also tended to dig a mine first, anyway, she gave money according to the amount, not on a daily basis.

Xie Yan proposed to dig this mine first, and then dig the next one.

Li Zheng, the earth system and storage space department, plus an S-class space system, the two partners as transporters.

After a few words, a list of plantings and a list of values were sent.

Anyway, after roughly touching a low, Tang Ranran was in a very happy mood, and kept humming in his heart: Today is a good day~

After sharing the survey results with Xie Yan, because the treasure hunt rat Zuozhou ran out of power and needed to rest and recharge, Tang Ranran also pretended to rest in his RV in the temporary camp, and kept the same schedule as most people.

A cave is constructed underneath for quarrying, while it is transported to the ground above, where the crushed stone is mined.

At this scale, the mining speed is absolutely leveraged.

With just a simple glance, Tang Ranran was clear.

That's right, Zuo Zhou, a treasure hunting mouse, can not only 'see' the spirit stone, but also judge the quality of the spirit stone according to the strength of the energy group.

Unconventional mining.

Unfortunately, there is no collector's item.

As early as when he was exploring underground, Tang Ranran had a whim.

The most expensive purification value of 10 also requires 2,500 tons to reach 2 trillion.

Most of them are pure medicinal materials, 60% are raw materials for red potion, 30% are raw materials for blue potion, and the other 10% are some special pharmaceutical materials, and the purification value is almost below 10, so the difficulty of planting is not high.

Of course, the special department, that's the same as opening a blind box, it's not something that you can draw if you want to draw SR.

You must know that 1 piece of medium grade is equal to 10 pieces of lower grade.

During the five-day exploration, nearly 100 top-grade spirit stones were dug up.

pointed out the direction, and Li Zheng, the soil system, dug a large rock layer down, and then knocked and cracked the surface stone layer, it was a superb spirit stone!

In the early stage, it will take at least a week to fill the lake, build the site, and wait for the personnel to enter the formal mining of the spirit stone.

However, if you draw a few more blind boxes, you can always open some surprises.

Xie Xingyun was very active in running and taking back the relevant seeds or plant seedlings.

The purification value of 1 ton is 10, which is about 800 million.

When he arrived at the artificial greenhouse, Tang Ranran first asked Xie Xingyun to contact the quartermaster minister.

Under normal circumstances, this project would be really huge, but it doesn't matter, with Zuo Zhou's cheat, you can accurately find the location of the spirit stone.

Moreover, Xie Yan will bring 20,000 mining troops over.

The watermelons and cantaloupes planted before were just for the soldiers to fight for their teeth, a small benefit in the snack category, which was donated to the 2 trillion yuan in the military area, which naturally had to consider practicality.

And so on, a top-grade spirit stone is equal to 1,000 low-grade stones!

The quantity is converted like this, but in fact, the difference between absorbing a top-grade spirit stone and absorbing and refining 100 medium-grade spirit stones is the boss.

Although she prides herself on being versatile, she has some abilities that her immortal cultivation techniques can't do.

What's more, the 2 trillion yuan that Tang Ranran promised was calculated according to the purchase price of the Quartermaster Department, and the purchase price was at least 20% lower than the market price outside.

The head of the quartermaster here is a middle-aged man, and as early as a few days ago, when she was planting melons, she jumped out to brush her presence and tried to hug her thighs.

It is definitely 1 high-grade spirit stone that can better assist cultivation and improve the cultivation of monks.

The melons before were her free gifts, not counted, but she promised to donate 2 trillion yuan, and she had to work.

Well, when she is empty, she will pick a few younger brothers, pull out the strength, and strive for another treasure hunt mouse with another function.

Grow vegetables, grow vegetables, grow vegetables......

Then, she made a high-profile decision to let it go...... As a result, only 50 tons were planted, and there was no fresh food box!

Tang Ranran: ......

Really, a spoiler! (End of chapter)
