Yinzhen and his grandfather went out early and returned late, went to see the scene in the county, let him identify which things were illusions and which were real, Yinzhen remembered them one by one, and when he got home, he recorded them carefully, everyone slept, and he also used the kerosene lamp to vibrate the pen and write.

Everyone let Grandpa Lin sleep at home, but he insisted on sleeping in the cave, and the next morning, Silver Needle was the first to get up and go to the cave to find Grandpa to teach him illusions, and the two of them would only come to the house to eat at noon.

When it came to the winter solstice, the pig brother opposite sent meat-stuffed dumplings, and the silver needle asked the grandfather not to go anywhere, and he made dumplings with everyone and gave them to the neighbors, so he agreed.

After everyone finished eating the dumplings, everyone had no strength, and everyone went back to the kang to rest for a while, Guo Jianhao didn't know how to make dumplings, his body was full of white noodles, and he went to the backyard to take a bath.

After taking a bath, he was washing clothes, and Grandpa Lin came over: "Young man, didn't you go with them to rest and come back?" ”

"Ah, Grandpa Lin is here, I'm not tired, I'm refreshed after taking a bath, and I can bask in the sun."

"The winter solstice is all about freezing off the ears before people eat dumplings, aren't you cold?"

"Thank you grandpa for caring about me, I have rough skin and thick meat, and I am not cold at all."

Guo Jianhao continued to wash clothes, and when he saw that Grandpa Lin was still standing next to him, he put down his clothes and stared at his grandfather: "Grandpa, is there anything wrong with you, I won't wash it, you said." ”

"I'm fine, I just remember what you want to do after you want to synthesize the Yin Yang Knife, I've seen the dragon scales you brought."

Guo Jianhao remembered that Grandpa Lin had seen the dragon scales, and he put down the soap horn: "I still have to collect the five major artifacts, and the dragon scales tell me that it will play a role when necessary, and I am just worried about whether these five weapons will make the common people miserable after they are gathered." ”

Grandpa Lin thought about it and said back and forth: "Young man, you come with me." ”

Guo Jianhao put down the basin and entered the secret room with Grandpa Lin, who was looking for a carving on the wall. Guo Jianhao saw him stop, and his eyes fell on a higher place.

"This is the method of fusing the yin and yang knife, the yang knife belongs to the yang, the yin knife belongs to the yin, you have me and I have you, if you want to synthesize the yin and yang knife, you must soak it in the yin and yang water."

"Grandpa, where is this kind of water, it's too difficult, it's a head one day?"

"Don't worry, the so-called river is not really the river water, you only need to put the water in a place where the yang energy is extremely strong, and then put the water in the place where the yin energy is heavy, and the water produced by the two is called yin and yang water."

"The Yang Knife is not refined by slaves, and the Yin Knife is not a plaything worn by dignitaries?" Guo Jianhao listened to what his grandfather said about yang and yin, and he was very puzzled.

"Not exactly, although the two of them are caused in this way, but the fusion has to be done in a different way."

"How do I know where the yang energy is extremely strong and the yin energy is extremely strong, and you won't let me dig the grave again, right?"

Guo Jianhao immediately thought that Yin Qi Sheng was the zombie tomb of the Taiye's Mansion.

"Today is the winter solstice, and when you get to the day of the light snow, you have to bury this yang knife in the snow on the day of the snow and let the sun shine on the snow water, so that the heat of the yang knife will dissipate, and the yin knife will have to be in the hot water every day to get rid of its yin qi, and when the snow water and hot water are fused together, the yin and yang knife will be formed, but what you have to do is to move quickly, otherwise the yin and yang river will be wasted."

The synthesis requirements of this Yin Yang Knife are so high, since in order to synthesize it, Guo Jianhao will definitely let them succeed. He looked at the process of making the Yin-Yang knife on the wall, and was surprised to find that the knife still had a handle in its final appearance.

This knife is like the knife he unleashed the first psychic beast, but how to make the hilt?

"Actually, it doesn't matter if the handle of this Yin-Yang knife is there, because the Yin-Yang knife nests on the handle, but on the mouth of the blade of the Yin-Yang knife."

"Grandpa, I don't know how to make a hole in the blade, you have to teach me, my blacksmith shop is also chasing ducks to the shelves, and I can't do a lot of things."

"It's not difficult, when you fuse them, I'll help you make holes in the Yin Yang Knife. You can prepare the boiling water of the Yin Knife now, but this winter, the boiling water will easily cool down, so you have to be careful. ”

Guo Jianhao kept it in mind, and the big deal was to live next to the boiling water until the light snow solar term passed.

He went to look at his unwashed clothes, only to find that they had frozen with the water. This winter is really cold clothes can be icy, he shook off his clothes, and suddenly found how some clothes are hot on the inside, but the outside is frozen.

Guo Jianhao shook off the ice ballast even harder, it turned out that he forgot to take out the dragon scales.

Is it hot inside and cold during the interview?

In this way, even cold water will not freeze, and the boiling water will not freeze as long as it helps the water not to freeze, and the temperature of the water will not let the Yin knife freeze into ice.

"Guo Jianhao, where is my grandfather?" Guo Jianhao was still throwing off his clothes, when he heard Yinzhen ask him.

"Huh? Grandpa Lin was in the secret room, and I was drying my clothes. ”

"My grandfather is not in the secret room, there is no one in the house."

Guo Jianhao's clothes fell: "No, he was indeed in the secret room at that time, you didn't go to the cave to look for him, he should be in the cave." ”

"I didn't find it in the cave, she didn't tell you anything?"

"He only told me about the synthesis method of the Yin Yang Knife, and then he didn't say anything, Grandpa was indeed still there when I came out."

Guo Jianhao and Yinzhen came to the secret room, and indeed, Grandpa Lin was no longer in the secret room.

"Look, this wall seems to be different from the past!" The silver needle pointed at the wall, and Guo Jianhao also found that the wall was different from before.

"This can't be an illusion made by your grandfather, haven't you learned illusion? You can tell at a glance! ”

"It's not an illusion, nothing has changed here, I found out, grandpa dug up a piece of the wall to make a weapon."

Silver Needle's fingers groped around the wall, he sensed what was going on on the wall, and then he stopped: "Here, here, I know a thing or two about the way grandpa used illusions, and there's a piece missing here." ”

Guo Jianhao leaned in to take a look, and suddenly exclaimed, isn't this pattern the production process of the Yin and Yang knife, why did Grandpa Lin do it? He took away the synthesis method of the Yin-Yang Knife?

"What? What happened? ”

"What Grandpa Lin dug up was the Yin Yang Knife synthesis method. He obviously told me how to synthesize, which means that a second person knows, so there is no need for this? ”

"Brother Yinzhen, Brother Guo Jianhao, can you come over and have a look?"

They looked up and saw Rong Rong, who was now at the entrance of the secret room to greet her.

Guo Jianhao and Yinzhen walked over, and Rong Rong handed over a letter in her hand to Yinzhen.

"Lin Yinzhen, grandpa will leave for a while, I will go to find my two sons, you have to practice illusion well, my little girl has some secret techniques of needle guidance, some of which are left by your mother, you have to concentrate on cultivation, don't live up to your father's expectations!"

After reading the letter, Yinzhen asked Rong Rong why she didn't tell him earlier and let her grandfather say goodbye, Rong Rong said that Grandpa Lin came to her, and I thought he was going to say something to me, but he pointed to my forehead, and I fell asleep, and when I woke up, I saw this.

"What about the secret technique, I haven't found it in this letter?"

This old man won't lie again, the silver needle wants to tear the envelope, and the credible paper can't be torn.

"I knew you were going to do it, you were exactly like your father, so this letter is an illusion, and when you unravel it, the secret will be revealed."

The letter changed to a different shape, leaving this sentence on it.

"The letter didn't leave grandpa, why did you erase the synthesis reason?"

Silver Needle shook his head, the letter really didn't say the reason, could it be the removed traces and the way to find Daddy?
