Yuan Yao, who fell into remorse and self-blame, shook his head, cleared some evil thoughts, and opened another book "New Edition of Papermaking" again.

After looking at it patiently for a while, Yuan Yao really saw the same thing on it again, an artificial paper machine.

And just like a joke, the price of an artificial paper machine is the same as the price of an artificial cement mixer, which is 2000 dim points, which made Yuan Yao squint slightly.

And there is a special note on the mall, A-level reward unique items.

Seeing the mention of the mall, Yuan Yao touched his chin thoughtfully.

It seems that these things were originally not available in the mall, but they appeared especially because of the task rewards.

After opening the rest of the books one by one, Yuan Yao really found a difference.

The price of the artificial brewing machine is obviously much cheaper, as long as 400 dim jun order one, and the price of artificial soap machine is even more crotch, only 80 dim jun order one.

This price is simply a drizzle for Yuan Yao, who has deep pockets.

However, while rejoicing, Yuan Yao discovered a guess that made him creepy that papermaking and cement making were both A-grade rewards, sorghum wine was B-grade, and soap was C-grade.

There is a 5-fold gap between these three required Faint Monarch Points, so what about the S-level reward Zheng He Treasure Ship?

If the speculation is true...

Yuan Yao opened the last book tremblingly, and found that there was no artificial machine on it, only instructions for the design and use of the hull structure, which made Yuan Yao secretly relieved.

But as he slowly flipped through it, Yuan Yao returned to the horror of Zheng He's treasure ship.

148 meters long, 60 wide, nine masts and twelve sails, the anchor alone weighs several thousand pounds, both in terms of the complexity of the manufacture and the technology required, it is a rather terrifying number.

Yuan Yao secretly estimated in his heart that according to the current technology, this is almost impossible to accomplish.

Yuan Yao, who was originally excited, felt like a basin of cold water was poured on his heart.

What's going on, is there a treasure trove in the air, but in the end it can only be seen and not used?

In front of the computer desk, Yuan Yao looked at the book in disbelief, and at the same time he was shocked in his heart, but at the same time, a deep sense of powerlessness also rose, although this thing is powerful, it is by no means a short time to be built.

Such a warship not only consumes a lot of money, but also requires a lot of craftsmen and manpower, and the moment it takes is definitely not short, which makes Yuan Yao hesitate in his heart.

But.

When Yuan Yao turned to the last page, his worried eyes suddenly changed.

Zheng He's treasure ship, 10,000 faint points.

This thing can be delivered directly, and it is a finished product?

The huge amount of money surprised Yuan Yao, but he couldn't help but secretly open his eyes, and his eyes flickered as he looked at the line of eye-catching big characters on the last page, and Yuan Yao searched directly in the mall.

When Yuan Yao entered Zheng He's treasure ship, the mall interface really appeared with clearly marked goods.

10,000 faint points!

There is also a special note on the mall, S-class reward exclusive items, limited to three purchases.

Purchase limit?

Is there still a purchase limit?

Glancing at the value of 37880 Dusk Jun points, Yuan Yao had an urge to buy three ships in one go, but after some calm thinking, Yuan Yao gradually calmed down.

Although this thing is limited to purchase, it is too expensive after all.

Although the total amount of nearly 40,000 Dujun points seems to be a lot, Yuan Yao has also used a lot of places, and it is very cool to buy three in one go, but it is not necessarily suitable for development.

And in addition to these rewarded items, Yuan Yao originally planned to buy hybrid rice seeds and corn sweet potato seeds on a large scale.

Different from the environment of later generations, Yuan Yao, who was in this era, knew the preciousness of food, and after the Yellow Turban Rebellion and the crusade against Dong Zhuo, the depression and barrenness of the entire country were outrageous.

Why was Yuan Yao able to gather hundreds of thousands of displaced people so easily?

On the one hand, it is because of the war, and on the other hand, because of the shortage of food.

In this era when even the dregs were not enough, Yuan Yao was able to provide light rice soup, and naturally countless hungry homeless people followed.

Therefore, Yuan Yao must take into account the high-yield grain seeds.

On the other hand.

Yuan Yao also has the idea of buying a large number of artificial cement mixers, because only a large amount of cement production can be crazy to build infrastructure in Yangzhou.

As a member of the Red Flag of later generations, Yuan Yao knows too well the importance of infrastructure.

If the motherland of later generations, if it were not for the title of infrastructure madness, how could it rise wildly in a short period of time, from a poor and backward developing country to a rich and powerful developing country, infrastructure is indispensable.

As a traverser, Yuan Yao is not a big man such as a scholar or special forces in later generations, but just a member of the crowd.

Therefore.

Yuan Yao didn't feel that he was particularly good at crossing over, and he could be more powerful than those heroes who could be famous in history.

While learning from the experience of later generations, Yuan Yao intends to defeat his opponent in the safest way.

If the 8-meter-high Shouchun Castle can be defeated by Cao Cao, then the 20-meter-high wall made of cement will probably feel desperate even if Cao Cao comes.

Food and infrastructure will develop together, and on the basis of food and clothing, business will naturally flourish.

With this idea, Yuan Yao had a general direction in his heart, as for Zheng He's treasure ship, Yuan Yao still planned to buy a finished product directly, although the price of one was very painful, but it was definitely worth the money.

If Qi Jiguang's sailors are equipped with such a giant, let alone along the Yangtze River, I am afraid that they will also have an absolute hegemony at sea.

After staying up all night, Yuan Yao came out of the Dum Jun warehouse with red eyes, walked to the side of the bed tiredly, and fell asleep.

The next day at noon.

Yuan Yao woke up from his sleep in a daze, a faint fragrance came to his face, feeling the soft touch on his chest, Yuan Yao saw a mature and hot face.

The person Yuan Yao was holding on to his chest turned out to be Cai Yan, and she was looking at herself calmly and intently.

Feeling his posture, Yuan Yao realized that it was not that Cai Yan didn't get up like him, but that the other party was hugged so tightly that he couldn't get up at all, and it was the first time that the two were in such close contact, and Yuan Yao was a little embarrassed.

Hey, I just said that the habit of sleeping with a pillow at night is not good.

Yuan Yao looked at the other party's tranquil appearance, his opened eyes suddenly closed again, and he didn't pay attention to Cai Yan who was surprised, and simply put away his arms and didn't speak.

Since you have hugged it, you can simply sleep in a comfortable position.

Cai Yan: ? ...
