The wall under the special construction method, in Cai Ruichen's view, is the essence of the wall.

Although the walls of ordinary construction methods seem to be very unheavenly, they are nothing compared to specially built walls.

After seeing the special ability to build walls, Cai Ruichen already had a very interesting idea in his heart.

This thing may not have any surprise effect when used in the wasteland world, but if it is placed in real space, it will definitely catch the opponent off guard for a while.

Especially when the opponent has already attacked the edge of his own wall, the wall suddenly emerges from the earth, and then the defensive weapons on it start instantly, which can definitely kill one piece.

However, the price is a bit pitiful, and the consumption is ten times that of a hundred-meter-long wall, which needs to cost 5,000 funds when it is built and hidden underground.

But as soon as he thought of the concealment and effect of this kind of wall, he immediately felt that when the base funds could be recovered normally every day in the future, this price would not seem to be expensive.

Although the first draw was fruitless, it also reduced the number of options for later extracts.

The second extraction, the function of the wall, made Cai Ruichen feel too powerful.

Excited, he couldn't wait to start the third ordinary drawing.

Twenty magic boxes appeared in front of him again, and Cai Ruichen, who decided to pursue the victory, decisively chose the fourth box.

"The result of the seventh extraction appeared - the ore extraction shaft, and the ordinary extraction was all extracted. The next draw time is six days later, and the commander can continue to accumulate the number of draws at once. ”

Looking at the icon of the ore extraction well floating in front of him, this thing, to be honest, was not what he wanted right now.

Because in Shaxi Town, which was finally recovered, there are 100,000 tons of refined iron ore, with a total value of 10 million funds.

Therefore, what Cai Ruichen needs most now is a magnetic energy reactor, so that the base can have electricity to replenish it, and then continue to build an ore refining plant.

With an electrically replenished ore refinery, it will not only increase the daily income, but also increase the number of armed mining vehicles.

For him, who is still almost poor now, an armed mining vehicle is equal to a powerful combat unit, and the combined firepower and lethality may not be comparable to even dozens of mobilized soldiers.

Around the base, there is not even a decent mineral, and the only mineral that is convenient to mine is only a small mineral, which cannot meet the long-term capital needs at all.

But then again, this thing needs to be built sooner or later, and it's better to have it at this time than not to get it all the time.

At least one step closer to the goal of building all those construction units.

Science and Technology Ore Extraction Shaft: Collect auxiliary units, the construction price is 10,000 base funds, the surface covers an area of 50 square meters, and the construction time is 6 hours.

Description: The use of advanced technology to develop the best automated mining units, each such unit, can dig up 10,000 worth of minerals per day. No matter how deep the mine, it is capable of digging and delivering the ore directly to the mining vehicle.

Tech ore extraction shafts can also be built in the ocean, but require a mining vehicle that can go underwater to transport the ore.

Construction Restrictions: This unit can only be built within the allowed construction range of the base, and cannot be built in the special construction mode of the base.

Note: When there are no minerals in the area of the ore extraction well, it will self-destruct without leaving any traces.

Suggestion: Select the construction quantity according to the situation of the mineral division in the surrounding area. The mineral density is very high, and there is an option to build more. The mineral division is too thin, please build less.

After wasting three extractions and harvesting two units, Cai Ruichen was in a good mood.

It was the early stage of development, and each draw was crucial, and the reason why he put the three draws together was also because of the possibility of drawing duplicate units.

finally waited for seven days, but there was not even a fart, Cai Ruichen didn't want to make his mood too depressed.

Accumulate a few more times, and then draw at once, there is always some gain, and maybe there will be surprises.

Three draws, two of which drew new units, also because there are many more icons to draw.

Cai Ruichen was a little unimaginable, if he went to the back and drew the remaining one among the ten or twenty icons, how tragic it would be.

Therefore, he can only pray that such a situation will not occur.

After seeing the rewards of the second power expansion mission, he even wanted to accumulate all the next draws to complete the second force mission, and use the opportunity of the four exclusions to draw all the remaining units at once.

However, this is just a thought, and that rare opportunity is naturally reserved for special extractions.

Once you add a powerful super unit, and then use this method, the probability of drawing a super unit will be greatly increased.

It's not like he didn't think about it this way, after extracting most of the things under the lowest level of authority.

A special extraction is then carried out, and the exclusion right is used to exclude those units that have been extracted.

If there are still three units left that have not been drawn at that time, isn't there a 1 in 4 chance of getting a super unit after adding a super unit?

And if you draw it four times, it doesn't mean that you can definitely draw a super unit.

It's just that Cai Ruichen doesn't know if the base will let him get his wish, otherwise it will be too rebellious, and it can even be said to be a bug extracted from the base.

But is there really such a thing as a bug in such an advanced base as a base?

Cai Ruichen still felt that he had taken it for granted, even if such a situation really occurred at that time, it should be regarded as the base deliberately fulfilling him.

"Base, you said twice the chance, is it possible to draw super units." There are still two special extractions left, and it is also the most nervous time, Cai Ruichen found that he was a little uneasy.

"It is up to people to do things, and the base believes that the commander has such a fate." Base Road.

"Oh, the base thinks I can draw super units?" Cai Ruichen said with some surprise.

"The base doesn't mean that, as long as the commander is strict with himself and always maintains a high standard of learning and training, one day, the so-called super unit will be very ordinary in your eyes." Base Road.

"How long is that time you are talking about?" Cai Ruichen asked.

"According to the current level of progress of the commander, ten years will be about the same."

"Ten years, I'm thirty years old, and I don't think I'm as excited as I am now. Love. Cai Ruichen shook his head and said noncommittally.

"Didn't you say that a man stands at thirty? If the commander can carve out a world of his own in the year of his establishment, he should be regarded as a great person. ”

"That makes sense, but I just want to know if I ever got the Super Unit today." Cai Ruichen said.

"I don't know the base, it depends on whether the commander has such God's luck." Base Road.

"Then tell me, what super units will be added to the two draws?" Cai Ruichen retreated and said.

"The super units that join temporarily are all random, and the base is not clear until the results are in. Moreover, the base will not control the extraction of the commander, because all the development of the commander must be carried out in the most natural state. "Base Road.

As soon as he heard the words of the base, Cai Ruichen's old face turned red, the reason why he suddenly said this to the base was just that he thought that this extraction was made by the base, and it must be controlled by the base.

And the base's final answer has told him in disguise that the base will not control the extraction results.

This made Cai Ruichen feel helpless, there didn't seem to be a shortcut, and it was time to really test fate.
