Although they used the talisman machine to talk to Zhao Ren and Zhao Yi, when the two sons really appeared in front of their husband and wife, Zhao Wuregret and his wife couldn't help but cry, hugged the two sons in their arms, and kept chanting: "It's good to come back, it's good to come back!"

Zhao Ren broke free and resolutely kowtowed three times: "Father and mother, the child is not filial, so you are worried!" Zhao Yi also stood up and arched his hand and pretended to be old-fashioned: "Father and mother, I finally lived up to my mission and brought my brother back safely." ”

During this period of time, I first heard that the eldest son was seriously injured and did not know whether he was alive or dead, and then the younger son had been gone for nearly half a year. was still sad, but when I saw my eldest son's actions, I only felt that my son's experience was not without gain, and he had really grown. Seeing the younger son pretending to be an old man speaking, I felt that my heart was still blocked in panic just now, and I felt much more comfortable for a while.

Zhao Wuregret helped Zhao Ren up and patted him on the shoulder, the appreciation and affirmation in his eyes were undisguised. Ye Wushuang snatched Zhao Yi, pinched his little face, kissed him again, and praised loudly: "It's really a good child of my parents!"

Zhao Ren took the opportunity to propose to stay at home for a few years and do his filial piety, Ye Wushuang was happy, Zhao Wuregret thought about it, and agreed very happily. The son has the heart to stay by his side to do his filial piety, that is a good thing, and with the current status of Zhao Wangfu, there is no need to worry about the future of his son, his son has the experience of commanding the army, and he has been training in the commercial building at home for two years, and it is more than enough to serve as the city lord.

A few days later, Zhao Ren needed to go to the academy to report on the experience of the trip, and set off early, promising to rush back before his younger brother Zhao Yi's birthday.

Zhao Yi's fourth birthday is approaching, and he is also very happy to be able to celebrate his birthday with his family. Just thinking of his birthday, which was also his mother's day of suffering, he decided to make a gift for his mother on his birthday. Feeling the increasingly cold weather, Zhao Yi thought of "What to send at this time is better than sending warmth!" An idea couldn't help but come to his mind.

Zhao Wangfu is not cold, every day the room is lit with charcoal, and he is also wearing a cotton jacket. It's just that Zhao Yi thinks that the smoke in the room is too heavy, and it smells uncomfortable, and the padded jacket is too heavy and it is inconvenient to do anything. He thought of making a warm baby, "The patch warms the baby, and it warms the whole day." With a warm baby, you don't have to worry about being in bad shape in winter. Zhao Yi laughed at his own prank.

This warm baby is still boring in his previous life to search on the Internet, the principle is very simple, using the oxidation reaction of iron to release heat to heat. All you need is iron, activated carbon, inorganic salts, water, and a few catalysts.

Iron powder was extracted from iron ore, and Zhao Yi instructed Liu Xia to go to Steward Zhao to deal with it, and it happened that there was an iron mine under the name of Zhao Wangfu. Zhao Yi didn't plan to make too many films at once, just a hundred or so films. Counting the wear, one or two kilograms of iron powder is enough. He found some coal and prepared to refine the activated carbon, and now that he has cultivated to the third level of Qi training, it is much more convenient to directly refine it with spiritual energy.

Soon Zhao Yi also refined several other main materials, and Liu Xia also brought iron powder. He mixed them together in a certain proportion and packed them into a spun cloth that had been prepared long ago, and made sure that air could get in and no liquid could come out, and a simple warm baby would have succeeded.

Liu Xia stepped forward to congratulate him and offered to do the experiment, Zhao Yi thought that he was not afraid of being injured if he had a healing charm, so he agreed to his request. After several tests, the stability and heat preservation of the warm baby are qualified, and Zhao Yi attached a special glue to it to ensure that it can be stuck to the clothes, and it will not damage the clothes after tearing it off, which is a great success.

Zhao Yi thought that this packaging box had to be handled well, not only to be beautiful and generous, but also to ensure that there was no air inside, once there was air, the effect would be greatly reduced, or even no effect. Make a packaging box at the moment, put the warm baby inside, put in a degassing charm to extract the air, and seal it completely, and a finished product is completed.

For the next period of time, Zhao Yi has been busy making the remaining warm babies, and he decided to make a hundred of them to show his 100% heart, but he also enjoyed it. After ten days of hard work, the production came to an end. Brother Zhao Yi finally rushed back, and seeing his relaxed appearance, it can be seen that this time it was very smooth.

"Brother, it's your birthday in two days, this is my gift to you!" Zhao Ren took out a brush and handed it to Zhao Yi: "This is my trial, the reward given by the academy, I heard that it was made by the dean of the academy himself!" Zhao Yi was not hypocritical, he accepted it directly, and said: "Brother has a heart, thank you brother!" Zhao Ren touched Zhao Yi's head dotingly: "What are we brothers doing so clearly, my brother's is yours, thanks to you being by your parents' side in the past few years!"

"What a beautiful box, what is this?" Zhao Ren asked in surprise when he saw the beautifully packaged warm baby. Zhao Yi woke up from his contemplation just now: "Ah, this is a gift from me to my mother!

Zhao Yi did not entertain guests on his fourth birthday, because he proposed that he wanted the family to have an ordinary birthday. Ye Wushuang handed over a piece of clothing made by himself to Zhao Yi as a gift, but Zhao Wuregret gave him a few books, obviously knowing that this son liked books the most.

Zhao Yi's heart was moved, and he hurriedly jumped off the stool, ran back to the room to retrieve something and handed it to Ye Wushuang: "Mother, today I am four years old, I have grown up, this is my birthday, and it is also your Good Friday, I want to say Mother, you have worked hard, this is my gift to you!"

didn't have time to check the exquisite gift in his hand, Ye Wushuang walked over and hugged Zhao Yi's head: "My son is really sensible, he knows how to make me happy, it's really my good baby!" Although he was moved by his son many times, today's behavior also touched him a lot, and it really hurt when he gave birth, but at this time he felt that even if it hurt ten times more, it was worth it. Zhao Wuregret is also very relieved, not because these two sons are capable, but because of their filial piety, the harmony between brothers, and the name of benevolence and righteousness that they have taken.

"Mother, I'll put it on you!" In the room, Ye Wushuang took off the cotton clothes outside, Zhao Yi opened the box, tore off the protective paper, and pasted the warm baby on the clothes on her waist. "Ninety-nine, I'll send someone to your room later. ”

The family waited for a while, and Ye Wushuang let out a voice in surprise: "It's warm!" only to feel a burst of warmth spread through his waist throughout his body. couldn't help but say again: "Brother Zhao, you can try it too!" Zhao Wuregret was a little embarrassed, this was given to his wife by his son, how could he ask for it.

Zhao Yi has no opinion, it is his wish to give it to his mother, his mother wants to show affection, of course he needs to be an adult, so he took one again and said: "Father, you can try it too, I will do it again if it is not enough, besides, we can build a workshop, and we will do this in the future, so we don't have to worry about the cold in the winter!"

Zhao Wuregret accepted it half-pushed, thinking about this huge market value, and said quite approvingly: "It's a good thing to build a workshop, but is this process complicated?

Zhao Yi thought of many other things, it was okay to do one or two by himself, but he couldn't be busy if he did more, so he didn't answer his father's question, but asked: "Father, brother, after learning the talisman, I have read many books, and I have many ideas in my heart that I want to realize, I can't be busy alone, can I find more reliable people, I can teach them, and I have some helpers?"

Zhao Wuregret thought of Fu Ji, thought of the huge market value of Nuan Baobao, and thought of his four-year-old son who was so busy all day that he didn't even have time to play, so he simply agreed, but this helper needed absolute loyalty, and he still had to tell Steward Zhao to go to the tooth shop.

Zhao Yi's fourth birthday passed like this, and everyone was very happy. It's just that he is not an idle person, and suddenly thought of the Assassin Heaven Alliance, he felt that it was better to improve the safety factor of Zhao Wangfu first, and it was time to make things for his father and brother!
