"Whew~ It's finally done. Zheng Yichen looked at the bottle of potion in his hand and awakened the potion...... Uh, it should be said that it is a semi-awakened potion, this thing has no original effect, and the duration of the maintenance is only a temporary amount, unlike the original design plan, once used, it will have a permanent effect.

But even so, Zheng Yichen is not worried about the sales of this thing, it is very simple, the effect of this thing is quite powerful! Of course, now these are all theoretical, if you want to understand more specifically, let Anne try it, and now Zheng Yichen was attracted to another thing, a team of alchemy puppets who went out did not come back......

Zheng Yichen has been developing the area near the underground base, after all, if you want to be self-sufficient, you still need to involve many aspects, not to mention other materials, at least the basic materials are indispensable, some of those materials can be bought, and there are many as long as you find the ore veins, there are many ore veins in this world that are hidden and undeveloped, Zheng Yichen has long been prepared to develop.

It used to be a problem, but now? It's just a trivial matter, a vein or something, as long as you find it, then find a way to throw a few alchemy puppets over, as for how the alchemy puppets operate there?

It's very simple, two of the alchemy golems put into the past are special types, they are Zheng Yichen's specially made 'Commander', with the same effect as the summoning ring used by Lily, they don't need to carry out any superfluous behavior in the mining place, and the thing they do is very simple, just be responsible for replenishment and statistics.

The excavated minerals can be sent back through the pick-up area, and after the pick-up area was established, Zheng Yichen has done related things, so there are already a lot of alchemy puppets distributed outside, and it doesn't matter if those alchemy puppets are discovered, anyway, their existence has long been known by the Templar Church, and they have been discovered, as long as they don't show their heads, there is no problem at all.

And every area where the pit is dug has relevant preparations, even if the location is discovered, as long as all the alchemy golems there are recovered.

All this is going smoothly, those alchemy puppets sent out transported back a large number of basic materials, maintaining the development and construction of the underground base, but today he had just finished the matter at hand, and an alchemy puppet in charge of recording submitted the information of the recently recorded anomaly to Zheng Yichen.

The alchemy puppet in charge of recording is the highest level in the entire underground base, and the alchemy core is made of the soul of the kind of high-end product that Loriss gave him at the beginning, and the intelligence is very high.

"Didn't come back...... Well, it's regular maintenance that hasn't come back. Zheng Yichen looked at the anomaly in this record and muttered, every once in a while, the mining alchemy puppets have to come back for maintenance, this time will not be too long, that is, three or five days, and maintenance does not take too long, basically it can be done in half an hour.

So even if something happens, Zheng Yichen can immediately determine what went wrong, and it's a recent problem!

"Area 23, even the commander puppet has lost contact? This can't be discovered and destroyed in advance, right? Who is full of food and support?" Zheng Yichen frowned more and more tightly the more he looked at the area of No. 63, flipping through the records, that place is just an iron ore area, how special is it, En...... The quality of the iron there is higher, and in a special word, it's 'cold iron', which is a little better than ordinary iron, but it is not a demonic material.

If you let that mining area grow slowly for a period of time, it is really possible to transform into a mining area that can produce magic materials, well, this is at least a few hundred years later, and the more important thing is that the place is remote enough, and the terrain is also extremely bad, it is a bottomless canyon, even if that ore vein is discovered, people who want to develop it have to consider for a period of time, whether to develop it here.

It is very difficult to supply this place, and the canyon stretches out and overflows with dark elements, those elemental powers are not very strong, but because of the constraints of the terrain, they are hoarded in the depths of the canyon, and over time a tidal reaction is formed, and if the accumulated elemental power is excessive, there will be a small eruption, and the black fog produced by the explosion of the dark element will overflow from that canyon.

Ordinary people have encountered it, and after being eroded by the dark element, it is time to go home to recuperate.

This kind of place is by no means a suitable mining location, otherwise a few people die every few days, even if this toss is to use slaves to go up, it may not be able to get back the corresponding income, it is this kind of place, it is suitable for Zheng Yichen to use alchemy puppets to carry out this kind of operation, in fact, the environment is similar to that here, and the environmental factors have a great impact, otherwise why would he maintain the alchemy puppets so often?

The maintenance time of the alchemy puppet working in Area 23 is four days, so the time to lose contact must be within four days.

"Hmm...... Tsk, have you even lost contact with the pre-stored alchemy puppet?" Zheng Yichen frowned slightly, in addition to the alchemy puppet in each mining area, there is also a special alchemy puppet with additional arrangement, and that alchemy puppet has a projection magic formation in it, and Zheng Yichen can activate and use them remotely.

These alchemy puppets are usually sealed in an egg silo, and their locations are also hidden, in order to deal with the situation in case of emergency...... But now even the means of prevention have gone wrong, it can be seen that the problem is not ordinarily small, Zheng Yichen was entangled for a while, and simply waved his hand: "Forget it, don't ...... it"

It's just a piece of land, and if it's gone, there's no more, and the situation is unknown, so why bother to take a look at it? Even the hidden mechanism has been demolished...... That's it, he struggled in the lab for a while, and finally slapped the record on the table, and yes, it really couldn't be forgotten.

The preset means have gone wrong, why don't you hurry up and find a way to figure out what's going on, what if someone gets to your own underground base?

Although Zheng Yichen has a long-term plan, to build the underground base into a fortress-like existence, it is best to be able to move and go to the sky, like the city in the sky, but this is a long-term plan after all, there are not so many resources in hand now, if you can't do it, you can't do it, after being discovered here, if you can get rid of the troubles, you can continue to develop, if you can't solve it, you can even attract the Templar Church...... MMP's, Benlong just wants to ignore the world's affairs with both ears, and only cares about his own development, why is there so much to do?

In a hidden cave, an egg silo disguised as a stone has an extra crack, an alchemy puppet walked out of it, it closed the egg silo and took a look at the surrounding situation, and walked forward along the narrow passage in front of it, after a certain distance, the narrow space suddenly became cheerful, dozens of alchemy puppets are in full swing, transporting the excavated ore to the designated place, and after accumulating to a certain amount, these ores will be transferred to the underground base by the leading alchemy puppet, and then refined into basic materials that can be used。

Regarding Zheng Yichen's appearance, those alchemy puppets still performed their tasks as if they didn't see it, Zheng Yichen didn't have the idea of interfering, dug a passage and left here, the entire mining area is closed, this mining area is the No. 22 area, which is the closest to the No. 23 area.

After leaving, Zheng Yichen controlled the alchemy puppet, looked left and right, and after there was no one, his fingers pulled on the side, pulled out a big crack, pulled a locomotive out of it, and rushed directly to the No. 23 mining area, and after arriving at the place to be reached, Zheng Yichen immediately discovered the abnormality here.

The black fog in the depths of the canyon is indirectly coming outward, and sometimes the black fog will gush out, but most of the time it is only in a state of yin wind gusts, but now, the black fog inside has been escaping outward, could it be said that this place is going to produce some kind of rare treasure!?

Seeing this scene, Zheng Yichen's spirits perked up, and he couldn't help but think, treasures...... There is such a thing as heaven and earth treasure in this world, to take the simplest example, that is, in some elemental veins, in addition to being able to produce rare elemental crystals, there is also a small chance of producing something that exceeds the specification, something called the elemental heart.

What's the effect of that? Let's put it this way, whether it's elemental ore or elemental crystal, it's something like a battery or a high-energy battery, and the elemental heart is a nuclear reactor...... It's not rigorous to describe it like this, after all, the elemental heart is already a different level of things.

It's just a trivial matter to consume it, and in many cases, the speed of consumption is not as fast as the Elemental Heart to produce elemental power, so the claims about this thing are still debated, is it that special vein makes the Elemental Heart, or is the Elemental Heart a vein?

The reason for the argument is that once the Elemental Heart is taken away, that elemental vein will be reduced to an ordinary elemental vein, but the output of this kind of thing is very random, and some super-large elemental veins are not necessarily available, while some medium-sized places with the same degree of qi purity as super-large elemental veins will appear.

Therefore, both of these arguments have always existed and are still in a state of debate.

Zheng Yichen doesn't know what is special in this canyon, anyway, as long as it is not artificially or something strange, there will be such an abnormal change, it is definitely caused by some kind of strange power, anyway, let's go and see the situation in the mining area first, the concentration of black fog overflowing in the canyon is not high...... It won't be discovered for the time being.
