"Next is the key, from the town hall to the main city, I don't know what will change?"

Qin Zheng thought in his heart, full of expectations for the continued upgrading of the city hall.

Unlike the farm, after upgrading to level nine, if you want to continue to upgrade, you must build a city hall, and the town hall does not have this kind of restriction, it can be upgraded almost infinitely, as long as Qin Zheng's resources, that is, the source wood and source gold are enough, it can be continuously upgraded.

Qin Zheng did not hesitate and directly continued to upgrade the city hall.

Main City: Level 0, the core building of the territory, has the effect of gathering luck, can convert luck into source gold, level 0 main city can transform luck every day, generating 1000 source gold, and has the ability to convert source gold into source wood, the conversion ratio is one to one, can be upgraded, upgrade to level 2 main city, need conditions: source wood 20000, source gold 20000.

Upgrading to the main city, the amount of source gold that can be generated every day has increased tenfold, and there is one more function, this function is very useful for Qin Zheng, this function is to be able to convert source gold and source wood into each other, for Qin Zheng, this is a very important function.

After all, the source wood is transformed by the actual substance, and the conversion ratio of one ton of material can get a source wood, if you want to get a large number of source wood, you need too many materials, tens of thousands, hundreds of thousands, Qin Zheng's identity, it is not difficult to get, but if it is a number of source trees that reach more than 100 million yuan, if Qin Zheng continues to transform the substance, it will attract great attention.

At that time, it will inevitably arouse the suspicion of others, those who have bad intentions will never let go of probing Qin Zheng's secrets, and before there is no absolute self-preservation power, it will be very unfavorable for Qin Zheng to be probed like this.

And with this transformation function, it can save Qin Zheng a lot of trouble.

Compared with matter, the acquisition of energy is much more hidden, as long as Qin Zheng pays attention to it, basically no one will find out that he has converted a large amount of energy into source gold.

"One thousand yuan gold a day, ten days is ten thousand source gold, one hundred days is one hundred thousand source gold, and one year is 365,000 source gold, so that even if I don't convert energy and matter into source gold and source wood, I can slowly accumulate source gold and source wood to build and upgrade ability buildings. ”

Qin Zheng thought happily in his heart.

However, after Qin Zheng upgraded the city hall to the level 0 main city, he did not continue to upgrade the main city, because continuing to upgrade required too much source gold and source wood, so it could not be upgraded by many levels, so Qin Zheng began to prepare to build other ability buildings.

With the existence of the main city, Qin Zheng's ability to build other ability buildings is unlocked and is no longer restricted, the farm can continue to be upgraded, and other buildings can be built.

At this time, the buildings that Qin Zheng wanted to build were not pastures or upgraded farms, but gold mines and lumberyards.

Gold Mine and Lumber Yard are also two mutated ability buildings, of which Gold Mine is an ability building that can generate source gold, and Lumberyard is a building that can produce Source Wood, these two buildings, which are basic buildings, must be built.

Qin Zheng's ability to build an ability building requires the consumption of source gold and source wood, so the building that produces source gold and source wood is the basic building that must be built.

Therefore, Qin Zheng prepared to build gold mines and lumber yards.

Gold Mine: Level 0, a building that can produce Source Gold, can generate 100 Source Gold per day, and is required to upgrade to the next level: 1000 Source Gold.

Gold Mine: Level 1, a building that can produce Source Gold, can generate 200 Source Gold per day, and is required to upgrade to the next level: Source Gold 2000.

Gold Mine: Level 2, a building that can produce Source Gold, can generate 300 Source Gold per day, and is required to upgrade to the next level: 3000 Source Gold.

......

Gold Mine: Level 9, a building that can produce Source Gold, can generate 1000 Source Gold per day, and is required to upgrade to the next level: 10000 Source Gold.

Then proceed to the upgrade.

Lower grade gold mine: level 0, a building that can produce source gold and spirit stones, can generate 10,000 source gold and 100 lower grade spirit stones per day, and upgrade to the next level requires: source gold 20,000.

Lower grade gold mine: level 1, a building that can produce source gold and spirit stones, can generate 20,000 source gold and 200 lower grade spirit stones per day, and upgrade to the next level requires: source gold 30,000.

......

Lower grade gold mine: level 3, a building that can produce source gold and spirit stones, 40,000 source gold and 400 lower grade spirit stones can be born every day, and upgrading to the next level requires: source gold 50,000.

Upgrading to a low-grade gold mine, in addition to being able to produce source gold, can also give birth to a by-product, that is, the spirit stone, although for the gold mine, it is only a by-product, but for the era of aura recovery, it is a truly valuable treasure.

In the era of Reiki revival, with the passage of time, all over the world, because of the aura, such a treasure as the spirit stone was born.

The spirit stone contains the ability of spiritual energy, which can not only assist human cultivation, but also can be used as an energy source.

In eight years, human science and technology have long discovered the existence of this kind of energy, if it were not for the temporary rarity of spirit stones, spirit stones could even replace oil and other energy sources and become new energy sources for human beings.

Even if oil has not been replaced for the time being, spirit stones have still become a strategic item in various countries, and every spirit stone is a very precious treasure.

And the inferior gold mine can produce spirit stones, and it is only a by-product, just such an ability is already a very anti-heaven building, not to mention, the source gold is the main product of its production.

"I don't know what kind of function the lumber yard will be born when it is upgraded to the next grade, or if there is an additional treasure that can be produced. ”

With the gold mine, Qin Zheng was full of expectations for the lumberyard, and after upgrading the low-grade gold mine to the third-level low-grade gold mine, Qin Zheng stopped upgrading the gold mine and began to build the lumberyard.

Lumberyard: Level 0, a building capable of producing Source Wood, 100 Source Wood can be born per day, and upgrading to the next level requires: Source Wood 2000.

Lumberyard: Level 1, a building capable of producing Source Wood, 200 Source Wood can be spawned per day, and it is required to upgrade to the next level: 3000 Source Wood.

Lumberyard: Level 2, a building capable of producing Source Wood, 300 Source Wood can be born per day, and upgrading to the next level requires: 4000 Source Wood.

......

Lumberyard: Level 9, a building that can produce Source Wood, can spawn 1000 Source Wood per day, and is required to upgrade to the next level: 10000 Source Wood.

Lower Grade Lumber Yard: Level 0, a building that can produce Source Wood and Refined Iron, can generate 10,000 Source Wood and 100 Refined Iron per day, and is required to upgrade to the next level: 20,000 Source Wood.

There is also an additional by-product of the low-grade lumberyard, which is refined iron.

Refined iron is a special material, through special acceptance, from the iron, can be refined from the substance, every ton of iron, can be refined a gram of iron, so although refined iron in the extraordinary era belongs to an ordinary extraordinary material, is the basic extraordinary material, but also one of the more precious materials, in the extraordinary era, the extraordinary field can be used in many places.

Therefore, the material of refined iron is definitely a very large material in demand in the future, and the abnormal building under the grade lumber yard built by Qin Zheng can produce fine iron, which is definitely very against the sky, and such a building in addition to starting to consume source wood or source gold to build, after construction, it can continuously produce source wood and fine iron, which is definitely a very anti-heaven existence.
