Tang Yin and Wei Chiyan glanced at each other, and immediately exclaimed: "At this time, what are you waiting for, hurry up and find a way!" ”

"I thought of a solution, but I don't have any money!" Lin Feng smiled wryly. What is the solution and how much does it cost? Tang Yin asked. Sure enough, he had a lot of money, but Lin Feng still pretended to be bitter gourd face: "The barracks we built last time can produce ten barbarian warriors per day, and the research institute can produce a catapult and a giant crossbow arrow, if there are more......"

"How much does it cost to build, you can say, is 50 trillion enough?" Tang Yin asked indifferently, this time you can't lose, if you lose again, you really won't have the face to see Jiangdong's father, let alone 50 trillion, even 100 trillion, you have to invest, after all, before, the money earned back was more than 40 trillion, as long as you can lay down a piece of the country, you still have no money.

After getting Tang Yin's reply, Lin Feng looked at Yu Chiyan again, and Yu Chiyan was also very refreshing: "Out, but, we can't lose this time, if we lose, we can quit the game!" ”

"Rest assured, there is no doubt that you will win!" Lin Feng immediately pocketed a total of 100 trillion yuan for the two of them, and then built ten barracks and ten research institutes again, spending a total of 80 trillion, as for the 20 trillion, of course, it was to fill his own shortfall.

Soon, players will see that on top of the mountain, rows of buildings have appeared, no more, no better, a total of 24 buildings.

With the internal defensive strength, it is not yet possible to determine the victory of the battle, Lin Feng is still pondering, whether he should build a harbor, build his own harbor, if he can, then he can block the other party on the sea, if he can fill the ship with cannons and the like, then ......

Lin Feng said his YD idea, Tang Yin and Wei Chiyan also agreed very much, and Quarkek, who was standing on the side, frowned and said: "Wang, the harbor and warships can be built, but we can't build the cannon you said, even if it is a research institute, if it doesn't reach a higher level, I'm afraid we can't study it." ”

What do you mean by that? Could it be that our institute can make cannons? Lin Feng and Tang Yin immediately asked in surprise. Qualkek nodded: "Cannons can't be made, but the arrows of our giant crossbow arrows are tied with explosives at the top, I think, if the institute can be upgraded, maybe it can make the cannon you are talking about, after all, the institute has now made gunpowder and explosives." ”

Lin Feng and Tang Yin glanced at each other, yes, human inventions are like this, there is gunpowder in reality, and weapons such as muskets and artillery slowly appeared, maybe, Qualkek's opinion can really be realized.

Thinking that he was about to do it, Lin Feng immediately checked the options of the research institute, and found that there was indeed a research institute upgrade inside, Lin Feng, who thought that the advanced level was already the top, showed a surprised look on his face, and clicked on the research institute upgrade, which prompted that the research institute can be upgraded by five levels, and at each level, a new weapon will appear accordingly, the advanced research institute +1, you can study the cannon, the advanced research institute +2, you can study the warship, the advanced research institute +3, you can study the ironclad ship, the advanced research institute +4, you can study a cruiser, and the Advanced Research Institute +5 can actually study an aircraft carrier.

However, the aircraft carrier here is not the same as the aircraft carrier in reality, it is just a very huge warship, the warship can be loaded with a lot of people and cruisers, of course, the defensive power and attack power are still relatively strong, looking at the model map, there are tens of thousands of cannons alone.

Of course, in addition to these war things, there are also some defensive ones, such as city shields, ship shields, etc., there are many, but they all require money and some materials to make.

Lin Feng first checked the materials needed for the Advanced Research Institute +1, the first point, the gold coins are specified, the upgrade cost is 1.5 trillion, and the materials need to be ...... It's actually ore, what is needed is ore, I went, for what would happen like this!

Lin Feng smiled bitterly, he didn't expect that in addition to money, the material was ore, and it was three kinds of ore, the first one, aquamarine ore, which needed to be measured in catties, a total of 10 units, the second kind, purple gold ore, was also 100,000 units, and the third type, dark iron ore, the same, 100,000 units.

"Male's Gobi, how can there be a sauce purple!" Lin Feng burst out foul language, Tang Yin and Wei Chiyan, who listened to it, were stunned, and then Lin Feng shared what they needed with the two of them, and after the two of them saw it, they also scolded, when did this happen, and they still had to let the player go mining.

"Made, brother-in-law, what shall we do?" Tang Yin asked. Lin Feng frowned and pondered for a while: "There are two ways, the first one, we dig it ourselves, but, I think, in this way, we will definitely not do it, so there is only the second way!" ”

"What's the solution?"

"Publish the task, make the acquisition!"

Lin Feng said decisively, and then asked again: "Who of you knows the price of the ore in the Dao Dao?" Tang Yin and Wei Chiyan both shook their heads, and Lin Feng said, "That's it, I'll go back and consult the price." ”

"Go back? Oh no, oh we're street rats now, and everyone fights us! Besides, we don't have that time, and once someone comes to attack, you're the absolute main force! Tang Yin said. Lin Feng smiled: "It's okay, just change your appearance, as for the question of time, you can rest assured, I have this!" Lin Feng took out the magic book and patted it and said.

Soon, Lin Feng opened a portal in the City Lord's Mansion, set a coordinate, and then drilled into the portal, when he came out, it was actually a corner of the Black Flame City of the Demon Realm, this was the portal set by Lin Feng at the beginning, Lin Feng set up a portal in the Black Flame City, Brother City and Tang Gate, and there was more than one, you must know that Lin Feng's magic book can set 30 portals.

Walking out of the portal, Lin Feng had already changed his name, and his appearance had also changed to another person, walking on the streets of Black Flame City, Lin Feng looked at it for a while, and found that many of them were members of the six major families, Lin Feng showed a smile on the corner of his mouth, don't worry, here, sooner or later, one day, I will get it back.

Entering the teleportation array, Lin Feng came to the Ghost Snake City, came to the blacksmith's pawnshop, Lin Feng asked about the prices of various ores, and felt that the price was not bad, one unit of azurite ore needed ten gold coins, purple gold ore needed fifteen gold coins, and the dark iron ore was multi-point, about twenty-five gold coins were needed, that is, these three things together were only 550 million gold coins.

Subsequently, Lin Feng came to the task release office, and immediately hung up three tasks, namely the acquisition of aquamarine ore, 10.1 million units, 10.1 million units of purple gold ore, and 10.1 million units of xuaniron ore, and then handed over the money to the task release office, and at the same time paid ten percent of the tax, Lin Feng returned to the super blood battle fortress.

As soon as he appeared, Lin Feng saw that there was actually a blood moon hanging in the sky, only to hear Lin Feng say lightly: "The blood moon is hanging in the sky, and blood is splashing the earth!" ”
