"Rain girl, I knew you wouldn't be able to bear to open it and take a look, but there was nothing in this wooden box. In fact, if you really can't do anything, you can give this wooden box to Lao Cao. Lao Cao has always been suspicious, and if I play such a hand, he may not be able to figure out my intentions, and he will naturally have more concerns about you. But what I hope most is that you can convince Cao Cao directly, and you yourself have to have confidence in yourself,"

Zhao Yu closed his eyes, his jade hand groped back and forth on the wooden box, and said secretly in his heart: "Sir, you also think too highly of me." But how do I do that? Alas, there has never been such a headache. ”

Withdrawing his hand and rubbing his temples a few times, Zhao Yu shook his head vigorously and said: "Forget it, if you can't figure it out for a while, don't think about it anymore, just enjoy this gentle sea breeze, maybe when you have a flash of inspiration, you will have a way?" ”

It may feel a little strange here, that is, how can Lu Ren have such a contrast? Zhao Yu's advice here is so light, but the advice to Lu Cheng is so mother-in-law and long-winded, is it because Lu Cheng is Lu Ren's direct descendant, so he has to take more care of it?

Actually, that's not the case. Lu Cheng and Zhao Yu are performing two different tasks, basically it can be said that Lu Cheng is carrying out internal affairs tasks, paying attention to step-by-step, steady and steady, and this kind of internal affairs itself is what Lu Ren is good at, and combined with Lu Cheng's personality factors, as well as the importance of the newly developed territory of Zhuya to Lu Ren's future development, Lu Ren will naturally advise Lu Cheng more.

However, what Zhao Yu wants to carry out is a diplomatic mission, this kind of task itself pays attention to improvisation, seeing and dismantling moves, and it is not the type that Lu Ren is good at, and Lu Ren himself does not know how to remind and tell Zhao Yu. In this case, why bother to excessively affect Zhao Yu's ability to exert himself? So Lu Ren chose to play some mysterious tricks. Give Zhao Yu more room for self-play......

――――――――――――――――――――

A few days later, Jizhou, Hebei, Nanpi.

Guo Jia was resting in the residence, but suddenly received a message, so he hurriedly left the residence to find Cao Cao. When he found Cao Cao, Cao Cao was in the barracks outside the city looking at the gifts brought by Zhao Yu with great interest. And among these gifts. Those local specialties from the south and subtropics, such as coconuts, bananas and the like, Cao Cao didn't care very much, what really interested Cao Cao the most was the more than 100 sets of armor that Lu Ren arranged for Zhao Yu to send.

Lu Ren has been mixed for so many years, so he naturally knows that things like armor are very valuable things in the era of the Three Kingdoms at the end of the Han Dynasty. Let's put it this way, due to the low level of productivity and resource development in that era, under normal circumstances, ordinary soldiers often had no armor to wear.

So not to mention metal armor. Even things like leather armor are often limited by the lack of animal husbandry. In general, only ordinary boss-level personnel can be equipped with a crude leather armor; The armor of the main leather and auxiliary iron, that is the treatment only of the generals or elite troops; As for the excellent armor of the main iron and auxiliary skin, it is not a high-class person with a head and a face, but don't even think about it. Take Lu Ren as an example, Lu Ren had been on the battlefield a few times at the beginning, but the armor that the official configuration for him was nothing more than a high-grade leather armor with metal parts in the vital parts. And Lu Ren as a civilian. I really can't get used to that.

It was precisely because of understanding these things that Lu Renyou and Shirley discussed the development of armor and armor. Don't think about metalwork for the time being. Yizhou's metal resources are too tight; Leather armor is also a bit difficult to handle, because islands like Yizhou are not very easy to engage in animal husbandry, and the number of whale and shark skins that can occasionally be caught from the sea is far from satisfying the requirements......

But! Yizhou has a unique resource at that time, that is, rubber! After a certain amount of chemical treatment, the protective ability of rubber will not be much worse than that of metal armor at that time. It is also lightweight, durable, and not easy to corrode. In addition, rubber itself is a renewable resource, and there is no problem in terms of quantity supply.

So in the end, according to Lu Ren's requirements, Shirley has produced a batch of initial models of rubber protective gear. In terms of their style, this batch of armor is a bit like ...... Like the body armor of later generations. After all, it's just an early model. All aspects of the process will take time to improve. And the remaining more than 100 sets of this batch, after adding several parts such as shoulder pads, were treated as gifts by Lu Ren, and now they have been sent to Cao Cao's hands.

With Cao Cao's status, the sophisticated armor at that time was naturally chosen at will, but Cao Cao was very interested in this kind of novel armor sent by Lu Ren. When Guo Jia walked to Cao Cao's side, Cao Cao was trying on one of them, and its light weight and good protective ability naturally made Cao Cao full of praise. Seeing that Guo Jia had already come to his side, Cao Cao smiled at Guo Jia and said, "Lone expected that Fengxiao would rush here immediately after hearing the news." Look over there! ”

Saying that, Cao Cao raised his hand and pointed to the car on the other side, and said with a smile: "There are hundreds of jars of good wine in the car over there, all of which are gifts from Lu Yihao to Yu Yatou." With so much wine, Lone can't help but want to ask Fengxiao for a few jars to get over the alcohol. ”

Guo Jia was stunned at the time, Lu Ren sent Zhao Yu here to deliver something? I said in my heart: "What is this kid doing again?" ”

Subconsciously looked around, but did not see the main Zhao Yu, Guo Jia asked Cao Cao. Cao Cao said with a smile: "After all, the rain girl is a girl, some things are not comparable to us men, and there are always some inconvenient things to avoid others." ”

Guo Jia said "oh", and said that Zhao Yu was either looking for a place to go to the toilet, or looking for a place to take a shower and change clothes, and the time when he came over was really a little unlucky. By this time, Cao Cao had already put on a full set of rubber armor, walked a few steps in place and ran and jumped a few times, and asked Guo Jia with a smile: "Fengxiao, what do you think about this armor alone?" ”

Guo Jia was not easy to follow his own topic when asked by Cao Cao, and after looking at it carefully for a long time, he frowned slightly and said: "This armor is not majestic and gorgeous, but it feels very light, but I don't know how it is protected?" ”

Cao Cao took the Hundred Refining Battle Knife handed over by the attendant. It is said that Cao Cao personally refined more than 100 knives when he raised his troops, and later named these more than 100 knives "Hundred Refinements", and its quality was indeed excellent at that time. At this moment, Cao Cao waved his hand a few times, but when he heard the sound of the blade breaking through the air yesterday, Cao Cao handed the war knife in his hand to Xu Chu on the side and said: "Zhong Kang, you are good at making a knife, and try this war knife of Lone." ”

Xu Chu had already felt a little itchy in his heart, and now Cao Cao handed him the knife and naturally grinned, took the knife and first checked it, and then split it according to a wrist-thick wooden stake erected next to him, and the wooden stake was immediately broken. Looking at Xu Chu again, he examined the war knife in his hand, and said to himself: "Good knife!" It's very easy to use! ”

At this time, someone else had fixed a pair of rubber armor on the stake frame, and Cao Cao motioned Xu Chu to try it, but of course Xu Chu cut it without saying a word. It's just that...... Rubber is not a metal, due to its material and other reasons, it has the corresponding toughness and elasticity, and has a very special protection against sharp weapons in many occasions.

Therefore, Xu Chu's knife went down, and the knife edge was stuck on the armor! When Xu Chu let go of the handle of the knife in surprise, the war knife still shook and shook a few times on the armor, and then it fell to the ground. If you look closely at this rubber armor, it only leaves a wound of less than half an inch in the place where it was cut.

"What is this? It's so tough!? ”

Xu Chu screamed in surprise, and the onlookers, including Cao Cao, all changed color slightly. After all, Xu Chu's strength is well known, and when he goes down with this knife, the ordinary leather armor is almost useless, even the poor metal armor can be cut out by him. But this rubber armor ...... Forget it, no more talk.

In this way, Cao Cao was even more fond of these more than 100 pairs of rubber armor, and immediately ordered someone to collect these more than 100 pairs of armor first, and then reward them to the appropriate soldiers. Even with it, Cao Cao also felt that Lu Ren sent someone to send such a valuable gift, if he just met Zhao Yu casually in the barracks here, it seemed that he had lost some of his part, and at the same time, it might make Lu Ren feel a little dissatisfied, so he decided to hold a small banquet in Nanpi City to entertain Zhao Yu, and it would be better to make a full number of courtesies.

It's not surprising that Cao Cao would make such a decision, it's like a friend coming to your house as a guest, and you originally thought that the other party was just coming over to sit down, so you can have two glasses of wine and chat with the other party; But when you suddenly find that the other party has brought a lot of gifts, is it too rude to just have two glasses of wine and a few idle words? And when the other party sees you so untreaching, no matter how good the relationship with you is, it will be affected a little.

And although the relationship between Lu Ren and Cao Cao is not a friend relationship, or it should be said that Lu Ren is more like the kind of little person who gives gifts to the upper leaders in front of Cao Cao in order to please him, but Cao Cao will not put on a show and show his majesty when he is full. You must know that Cao Cao also has an inexplicable fear of Lu Ren in his subconscious, but Cao Cao himself didn't realize that he had this mentality.

In short, the relationship between Cao Cao and Lu Ren is very delicate. Therefore, if Lu Ren casually sent someone over to say hello and cheer for Cao Cao, Cao Cao would naturally treat it with the attitude of "gentlemen's friendship is as light as water"; But if Lu Ren sent someone to send a heavy gift, there was a lot of going on between his actions, and Cao Cao naturally didn't want to lose his courtesy......
