After retreating from the plateau, Tian Tiannan turned his target to the spurs of the Yuyu Mountains, using the main peak as a reference to bring all the surrounding mountains within 500 kilometers under control.

There is no other reason, that is, for the rich mineral deposits in the mountains, especially the five important mineral deposits of iron ore, copper ore, coal mine, sulfur ore and saltpeter ore, the purpose is very clear, Brother Tiannan needs to make the Tiannan tribe can truly achieve comprehensive self-sufficiency, even without him, it can continue to operate intact.

For this, it is necessary to have enough veins in your hands!

In the middle of the seventh month of the Prayer Calendar, through the Lotus Fish Tribe, Tian Tiannan learned about some major events that had occurred in the world above.

First of all, the first fifth-order priest was finally born in the sixth-layer world, and then, like mushrooms after a rain, one after another, the main cities of the strongest tribes in the entire world were upgraded one after another.

Judging from the "top secret" information revealed by Ye He, there are figures from the seventh-layer world everywhere, and there is even a saying that someone from the seventh-layer world has descended to the middle third-layer world.

"It is said that the upper three layers of the world have not been connected with the lower world for nearly a thousand years, this time, it should be because of the return of the superior people, the reshuffle of the upper world has begun, which has affected the middle three layers of the lower world..." These are Ye He's exact words.

But not only the middle and third layer worlds, but even the Heavenly Prayer Realm has been seriously affected, and more and more people from the upper realms have come down to do things.

This is the aftermath of the upper-level game, the five bigwigs who broke out of the seal are like a key, opening the door to the evolution of this world, the sixth layer of the world has broken through the bottleneck of nearly a thousand years, and the next time is bound to usher in a blowout for a period of time, the whole world will become stronger rapidly, and at the same time, the battle between each other will become more intense.

The people of the upper realm descended to the lower world with this, and the impact on the lower world made the world's combat power instantly increase to a large stage, which was undoubtedly a forced evolution process.

Pray for the Heavenly Realm, after the fall of the southern part of the heavens, the Lotus Fish Tribe also raised the tribes controlled in this world to the advanced tribal level, and then, just like what is happening in the sixth layer of the world, high-level tribes have appeared in all races.

Therefore, Tian Tiannan's original bold promise to drive all the people in the upper realm away could not be realized for the time being, in order to keep his one-third of an acre of land, he had to only leave his life-saving old book, and then continue to invest the transferred sacrificial source crystal into the construction of the tribe.

First of all, in order to strengthen the defense, the Tiannan tribe and the poor tribe have independently arranged a source crystal array, and tens of thousands of sacrificial source crystals have been smashed down, including the main city of the tribe of Yucheng, and even the source crystal array with two sub-tribes has been upgraded to level 3.

The poor tribe, as the most important food producing area, has also become the third big money-burning household after the grassland star, and the tribe's own structure remains unchanged, but Tian Tiannan has established three production bases of the same scale around the poor tribe, which are next to the original poor tribe.

As a result, the new poor tribe expanded from 9 square kilometers to 36 square kilometers, and the moat between the four production areas was used for fish farming, and the moat was re-excavated outside the production area with a width of 50 meters and a depth of more than 10 meters, and the suspension bridge was eliminated, and the communication with the outside world was carried by boats, and a large number of high-grade piranhas and piranhas were kept in the moat.

These murderous guys swarmed up, and once the existence below level 20 descended into the river, the bones would be lost in minutes.

Then build a high wall in the tribal moat, the tribe's defense is enough, and far away in the grassland star, now there is no shortage of women and children, with a wave of his hand, Tian Tiannan transferred tens of thousands of women under the age of 30, with them, the poor production area does not need to worry about the lack of manpower.

The poorly cultivated tribe that has expanded its area will have an output value of about 120,000 sacrificial source crystals per month if they still use iron rakes for farming. This month's income is a bit reluctant for the Tiannan Tribe, which now has a population of nearly 200,000, after all, there are so many people, just buying life money will cost hundreds of sacrifice source crystals a day.

Fortunately, now that the Lotus Fish Tribe is a partner, the products sold to them are 4 times that directly exchanged to the system, after all, the system is the cost price, and even so, the Lotus Fish Tribe still has a good income when it changes hands again.

Therefore, Tian Tiannan only used iron rakes to cultivate in one of the four production areas of the poor tribe as a way out, and the other three areas all used diamond rakes. As a result, grain and vegetables are harvested once a day, and the half-year harvest of fruit trees is reduced to quarterly harvest, and the quarterly harvest is reduced to a monthly harvest.

Although this is very likely to make the transaction price lower by the Lotus Fish Tribe, the income will be more than ten times higher than that of direct exchange to the system.

In the next few months, Brother Tiannan began to slowly increase the amount of supply to the Lotus Fish Tribe, as he thought, the supply was large, and the Lotus Fish tribe was naturally not willing to buy at the previous price, and after several negotiations, the purchase price of each product was finally cut by two percent.

However, the unit price has become lower, but the trading volume is ten times that of before, for the Lotus Fish tribe, they can have more power to exert their strength, and on Brother Tiannan's side, the monthly income has easily exceeded 500,000 sacrificial source crystals.

This is not the end, after having money, he directly expanded the number of logistics attendants in the tribe to 10,000 in one go, of which the oldest 1,000 people are full-time scientific researchers, with the highest level of their 5th level logistics attendants, and make every effort to complete the science and technology tree for Tian Tiannan.

The other 1,000 people with less seniority were divided into five teams, each leading the new 8,000 peers to start establishing the industrial system of the Tiannan tribe.

Iron and steel smelting, weapons manufacturing, handicrafts, light industry, and the technology developed by the research team continue to enrich the industrial system of the tribe itself, which is built on the system workbench of the southern tribe.

As a result, more refined standard weapons and armor began to be sold to the Lotus Fish tribe in the first place, and at the same time, various daily necessities, pots and pans, clothes and even luxury goods came out one after another.

Because of the bronze sacrificial power containers that Tian Tiannan continued to supply to the Lotus Fish Tribe, now they have gradually spread in the fourth layer of the world, with it, the Lotus Fish tribe has opened countless trade routes, and in this chaotic period, it has seized the opportunity to grow like an upstart, and has become the commercial overlord of the fourth layer world in a few months.

"Tiannan, if you go on like this, I'm afraid our relationship with the Lotus Fish Tribe..." Gradually, the people around him began to worry that the growing Lotus Fish tribe would have bad thoughts about the southern tribe of Tiannan, so at a family dinner, Yourong raised their concerns on behalf of everyone.

"Hehe, uncle, you must know that the initiative is never in their hands, if they don't know what to do, I can change people immediately!" Smiling and answering everyone's worries, Tian Tiannan was not worried at all.

In fact, he does have this confidence, for several reasons: the first point, the Heaven Prayer Realm will not allow the existence of power that exceeds this world too much, which can be seen from the fact that the Heaven Prayer Realm cannot give birth to a real city level tribe, so in the Heaven Prayer Realm, Tiannan is now invincible, if the Lotus Fish Tribe really swells, then Tian Tiannan can immediately terminate the cooperation with them, and replace it with an iron rake Although the output value will be affected, it will slowly accumulate, and when his wings are full, he can directly occupy the entire Heaven Prayer Realm, Truly complete the previous rhetoric.

And the second point, which is also his biggest reliance at present, is the sword of the big guy that he stole in the first place.

When his account funds officially broke through the million yuan crystal mark, the system seemed to have received great benefits recently, so in order to digest these benefits, the system seemed to have been upgraded to another level.

After upgrading, Brother Tiannan, who is sitting on millions of assets, can finally use the sword through the assistance of the system, and an attack needs to consume at least 100,000 sacrificial source crystals, according to the killing estimate given by the system, the 100,000 sacrificial source crystals can easily kill a bloodline warrior with one blow, even if it is now at level 3 of the source crystal array, a sword poke will be a big hole, and the lethality will reach at least 100,000 terrifying values.

In addition to the fact that using it may cause big trouble, it is definitely a sharp weapon used to save his life at a critical moment, so he is not afraid of someone plotting against him now, and he will shrink in the Heaven Prayer Realm if it is a big deal, even if those big guys know that the sword is here, they can't do anything about him, and the guy who is qualified to come down is not his opponent at all.
