After the two sides negotiated the alliance, Sun Lin and Di Lina discussed the trade between the two countries, of course, this is not the kind of agreement that is signed casually, and then the two countries open their borders for the merchants of both sides to trade, if it is just that, it will not be the heads of the two great empires who are powerful and powerful talking to each other here, but will leave this kind of issue to the diplomats of the two sides to agree.

"It's hard to refuse the bargaining chips that the Dark Dynasty has offered." Looking at the dazzling "goods" written on the animal skin paper, people like Rao is Sun Lin who had passed through the big scene also began to jump their eyelids.

In fact, what the Dark Dynasty provides is not important, it is really not very important, because the Dark Dynasty only writes 1 ordinary ore in this trading agreement: iron ore, and in addition, the jewelry, gold, silver and various rare ores that are abundant in the underground world do not appear in the agreement, obviously this lady has only two possibilities to do this, the first is that the Dark Dynasty she owns will also use it. After all, the most powerful race of the Dark Dynasty is the Spider Race, and this race exists as a matriarchal society, plus the vast majority of female Spider Tribes are born with a unique sense of possession of those precious metals, of course, the Dark Dynasty is not willing to directly sell these precious metals to the Great Empire on which the sun never sets; Another possibility is that the woman seems to let the goods flow into the public market, rather than directly placing them in the trade between countries.

Although this does not guarantee a stable income, as the value of these precious metals fluctuates from day to day, and if the merchants on the Spider side grasp the opportunity, they can make a lot of money, which is obviously more in the interests of these underground races, who are currently desperately lacking in surface time currency.

However, although the two sides are only willing to trade iron between countries, this kind of trading volume of basic strategic materials almost made Sun Lin's jaw drop, because the iron ore given by Di Lina to supply the Underground World Empire for a year will be 10 million, followed by a ton of words! What does this mean? This means that as long as the Great Empire can continue to be friendly with the Dark Dynasty, then the Great Empire will receive 10 million tons of rough iron ore every year. And with so many iron ore rough stones, Sun Lin firmly believes that the annual steel output of the Sun Never Sets Empire should be increased by at least half a time, after all, the Sun Never Sets Empire does not lack steel processing plants, but the Sun Never Sets Empire lacks foundries and raw materials, and the Dark Dynasty provides so many iron ore rough stones This time is equivalent to giving the Sun Never Setting an opportunity for the development of the foundry industry.

And if the iron ore rough trade gave the sun an opportunity for the development of the foundry industry, then the second condition provided by the dark dynasty was to give the sun the great empire a driving force for the development of the foundry industry - a total of more than 1.2 million dark elf slaves, even if the old and the young are excluded, only young men and women are retained, and their number has reached more than 900,000.

Indeed, the elves have always been known for their weak physical strength, otherwise the elves would not have been able to make a decent heavy warship until now and could only replace it with a better light armor, and as a branch of the ancient elves, the dark elves, they agreed to inherit the elves' weak system, but from this point they really could not become a qualified caster, but their arrival also made Sunset nearly 1 million more forging apprentices who could at least refine iron ore rough to ordinary steel.

For what? It's very simple, because the elves are born to be excellent gardeners and planters, and even in many cases, an elf farmer can be worth 3 human farmers, because having elves who can communicate with plants can make the final maturity of those agricultural products planted in the field reach the desired value, with these million dark elf slaves to join the agricultural production of the empire on which the sun never sets, they can replace at least the same number of human farmers, and Sun Lin can arrange these idle laborers to become forging apprentices, Join the Empire on which the sun never sets, and process rough iron ore in the forge workshops set up in various cities.

"So, beautiful lady, I wonder how much you want me to pay for these things? Although he was already ecstatic in his heart, Sun Lin still showed Di Lina a face of more and less indifference to these conditions on the surface, after all, everyone wants to exchange less for greater benefits, this is human nature, and Sun Lin is of course no exception.

"Armor, we need excellent armor, and the full-body plate armor that your Great Empire has designed for warriors of other races is a reward for our best." Di Lina was not pretentious, and directly told Sun Lin what the Dark Dynasty needed and her own hardships for the Dark Dynasty army: "Do you know that although the mineral output of our lower world is extremely rich, because of the fact that most of the underground areas cannot make fire, the forging skills of our underground world are not as good as even ten thousand years, and even because our underground world has not been in contact with the surface world, we can't forge excellent steel at all, let alone those steel plate armor." Perhaps due to the way we fight in the Underworld, our Dark Dynasty does not have a high demand for armor, but now that we have come to the Underworld Realm, for this Underworld Realm that can use long-range weapons, how ridiculous is the sturdy flesh of our warriors in front of arrows, so we urgently need a lot of armor and weapons to equip our warriors, and although the Vampire Empire can cast armor for us, it is a pity that their super heavy plate armor suitable for heavy cavalry is not what our Dark Dynasty needs, On the other hand, the full-body plate armor that your Sun Never Sets Empire has designed for other races is indeed the favorite of our warriors, so I want to exchange the plate armor we need from your Sun Never Set Empire for my army. As for the cost and labor costs, it doesn't matter, although our Dark Dynasty currently does not have the currency of the Earth World, but we are willing to use a large amount of mineral raw materials to continue to want you to exchange after those two chips are consumed, I just want to say that now our Dark Dynasty's need for armor is as much as possible if the sun does not set. ”

"Hehe, don't be so polite, since we are already allies, of course we will not sit idly by and ignore the dilemma with the ally army, beautiful lady, in fact, this time I brought the army here, and I also brought you a gift, and I hope you will smile." As he spoke, Sun Lin took out a horn from his bosom and blew it, and not long after, 30 Kodo beasts pulled huge trailers wrapped in gray cloth to the central square.
