"Mom and Dad, please come in. I'm going to stay at Jiajia's house for two days, and I'll bring her back with me on the fifth day of the Lunar New Year." Zhang Song got into the car and said to Zhang's father and Zhang's mother who were standing at the door. Zhang's mother worriedly asked: "Behave well when you get to Jiajia's house, and don't let Jiajia's parents have any objections to you." "I know, Mom, don't worry, I'm leaving." Zhang Song waved his hand and opened the car window. He closed the door, drove out of the villa, and drove towards Qing'an in a fast speed. At noon, Zhang Song arrived at Song Jia's house. Song's father and Song's mother had long known that Zhang Song was coming, and had already prepared food and drinks at home. "Come on, come in and have a rest. Are you hungry? We'll eat soon." After Zhang Song carried the things upstairs, Mother Song said with a smile on her face. "Auntie, I still have some things in the car. I'll go downstairs to get them." Zhang Song was already used to Mother Song's enthusiasm, so he said with a smile. "Don't worry, I'll get it after you finish eating. Xiaosong, you can have a drink with me later." Song's father said from the side. "Okay, just listen to uncle." Zhang Song nodded and sat next to Song's father. Song's mother said a few words to Zhang Song and then went into the kitchen to cook. "Zhang Song, you're here." Song Jia walked out of the room and said happily. "Yeah." Zhang Song was also very happy. He hadn't seen Song Jia in the past few days. Although the two of them had video calls every day, after seeing him in person, he realized that he still missed her very much. Zhang Song and Song Jia chatted with Song's father for a while, and Song's mother's meal was ready. In order to entertain Zhang Song, Song's mother cooked a large table of delicious dishes. Zhang Song drank a few glasses of wine with Song's father. , all they drank was the golden wine brought by Zhang Song. At night, Zhang Song and Song Jia were lying on the bed. After a while of lingering, the two fell asleep. Zhang Song stayed at Song Jia's house for two days, and returned to Songjiang with Song Jia on the fifth day of the lunar month. During these two days, Song's father and Song's mother took Song Jia and Zhang Song to visit several relatives. Let Zhang Song show his face in front of relatives and friends. Zhang's parents and Zhang's mother were very happy when they saw Zhang Song and Song Jia coming back. Zhang's mother held Song Jia's hand and talked for a while, as if they hadn't seen each other for a long time. When Song Jia handed Song Jia the gift she had brought, Mother Song felt even happier when she was pregnant. "Mom. Let's talk. I'll go to the wine cellar and have a look." Zhang Song saw Zhang's mother and Song Jia chatting enthusiastically and said to them. After entering the wine cellar, Zhang Song did not stop here and directly entered the Qingmu Cave. I haven't entered Qingmu Cave in the past few days, so Zhang Song came in specially to take a look. As soon as they entered the Qingmu Cave, Qilin ran down from the Qingmu Mother Tree, biting Zhang Song's clothes and dragged him towards the thick fog. "What are you doing, Qilin? Can't you just let me go and I'll follow you?" Qilin's mouth was full of sharp teeth and tore Zhang Song's clothes. Zhang Song said helplessly. "Ho ho ho" Qilin listened to Zhang Song's words. He loosened Zhang Song's clothes, yelled at him twice, and then led the way. Let Zhang Song follow him. Zhang Song straightened his clothes. He could only pretend that he didn't see the two slits in his clothes, and followed Qilin towards the direction of the thick fog. "So this is what I'm looking at. Didn't I already see it a few days ago?" Walking through the dirt slope between the pond and the fish pond, I came to the edge of the thick fog and found that a large area of ??new land had been opened up by Kirin. It is about more than 100 square meters, several times larger than the last time Zhang Song came here. "Ho ho ho" Qilin roared again. He came over again and tried to bite Zhang Song's clothes. "Okay, what else is there to see? Shall I go with you?" Zhang Song quickly dodged and followed Qilin inside. Walking to the side of the thick fog, Zhang Song took a closer look. There was a big pit under the thick fog, two or three meters deep. Half of it was on the side of Qingmu Cave, and half of it was inside the thick fog. It turned out that this was what Qilin wanted Zhang Song to see. something. "Qilin, this appeared after you absorbed the thick fog." Zhang Song squatted down and asked Qilin in surprise. Qilin shook its big head and roared into the pit. Zhang Song didn't know Qilin's intention and could only watch. After a while, more than a dozen things that were more than 20 centimeters long, as black as ink, and looked like earthworms crawled out of the deep pit. "What is this? Could it be that it was hatched from the dozen black eggs a few days ago." Zhang Song was startled and couldn't help but make a sound of surprise. Qilin nodded beside him, indicating that Zhang Song was right. When they crawled to Zhang Song's side, Zhang Song saw what they were. According to the information in his mind, this kind of thing was called an earth dragon, which was something similar to earthworms. It was considered a kind of spiritual beast, but they didn't have What attack capabilities, but their usefulness cannot be underestimated. The Earth Dragon has two abilities. The first is to turn over the ground. In the past, the owner of Qingmu Cave Heaven used the Earth Dragon to turn over the ground and uncoveredThe ground here is softer, so anything you plant will come naturally. The second ability of the earth dragon is digging. The earth dragon can swallow soil. An earth dragon can swallow dozens of times the volume of soil of its body every day. Moreover, after the earth dragon has swallowed the soil, it can also spit out something called a dragon. Glue, this kind of thing is like cement. It can bind soil and is very strong. In the past, the owner of Qingmu Dongtian used this kind of dragon glue to build various houses, cellars and other buildings. This is all Zhang Song knows about the uses of earth dragons, but for Zhang Song, the two uses of these earth dragons are of little use to him, and they can only be kept as pets. Zhang Song doesn't want to plant anything else in Qingmu Cave now. The earth dragon's ability to plow the ground will be useless, and the dragon glue spit out by the earth dragon is of little use to Zhang Song. Nowadays, reinforced concrete is used to build houses. Who can He knows how to use things like dragon glue, and even if Zhang Song wants to build something, he doesn't dare to take out things like earth dragon. "Are these two abilities of Earth Dragon really useless? What if" Zhang Song suddenly had an idea in his mind, but it passed by for a moment. Then Zhang Song shook his head, squatted down and took a closer look at the Earth Dragon at his feet. After that, Zhang Song jumped into the pit. The pit was two to three meters deep and about four to five meters long. He had already entered the thick fog. When he saw this situation just now, Zhang Song was very surprised. It turned out that the thick fog only covered On the ground, it cannot be covered underground. However, Zhang Song then thought that when part of the pond was just exposed, he also tried, but could not enter the other half of the pond through the bottom of the water. The middle of the pond was separated by thick fog, but now the earth dragon can dig the hole. Going underground in thick fog, this made Zhang Song a little confused. He didn't know if it had something to do with the earth dragon, or if it was because of the difference between land and spiritual water. After thinking about it, Zhang Song gave up thinking about this problem. There were too many problems in Qingmu Cave for Zhang Song to understand. If he wanted to understand every problem, Zhang Song would die of worry. (To be continued)
