Previously, the Lin family was inconspicuous, so naturally not many people noticed this low-key spring and shock absorption system.

  But after the Lin family rejected the Gao family's marriage, the Gao family specially investigated the situation of the Lin family.

  There has been a detailed investigation of the various industries of the Lin family, and it goes without saying that the soap has reached a cooperation with the Li family, and it is not so easy to get started.

  But this shock-absorbing carriage really amazed the Gao family, just a small change, but it made the long-distance journey much less tiring.

  The Gao family plans to make a move on the Lin family, and of course Master Lin is not an ordinary person, although he doesn't know that the Gao family is eyeing him, but he is still keenly aware of it.

  That little spring, Master Lin has also studied, although I don't know what other functions it has, but it can obviously be used in bows and crossbows, if used properly, I am afraid that it can raise the entire weapon to a higher level.

  After all, simply using it on siege equipment can greatly increase the range and power, and when Master Lin discovered this use, he thought about when to dedicate the spring technology.

  Now someone happened to be eyeing the shock-absorbing carriage, so he simply threw this hot potato out and used it as a capital for his son, after all, his son wanted to be a colt, but he didn't want to be a vassal, so naturally the more capital he had, the better.

  Lin Yunfeng followed his father-in-law to the emperor and hurriedly saluted.

  "Okay, let's not talk about these false courtesies, now it's just you and me, let's get along as ordinary sons-in-law."

  The emperor looked at the young man in front of him, and the melancholy in his heart because his daughter was going to marry was reduced a little.

  After all, she is already sorry for the first queen, and the only heir she left behind can be happy, which can be regarded as an explanation.

  "I don't dare." Lin Yunfeng is a more rigid person.

  "What dare you dare." Zhao Yuyu, who had already hidden behind the curtain, walked out delicately and spoke.

  "I've seen the princess." Lin Yunfeng was still very polite.

  "Yunfeng, since my father said that today is a private identity, then don't be so restrained, and you still call me a princess, but you are not satisfied with me."

  Zhao Yuyu didn't follow it first.

  "Yu Yu." Lin Yunfeng saw his sweetheart's coquettish appearance, and couldn't help but call out.

  "Yes, that's right, otherwise I really want to doubt what Yu Yu said to me, whether it's true that you are in love with each other."

  The emperor also laughed when he saw Lin Yunfeng's change of attitude.

  "By the way, there seems to be something wrong with your Lin family?" When the emperor saw Zhao Yuyu, who kept giving him a look, he thought of his gossip heart, and said again.

  Lin Yunfeng naturally saw that Zhao Yuyu had been giving the emperor a look, and his heart was greatly moved, this matter was originally his own business, and his sweetheart was so attentive, and his heart was even more sweet.

  "That's the case, I also want the emperor to help me make the decision this time, and our Lin family has two small inventions to dedicate to the emperor."

  Lin Yunfeng replied respectfully, he has never been able to break away like his sister or Dongfang Bai, the rules are in his bones, and it is already his limit to call his sweetheart Yu Yu.

  "Okay, I'll listen to your Lin family first." The emperor couldn't imagine that Lin Yunfeng would not only let himself be the master, but also have gifts for himself, and he also laughed.
