"Mom and Dad, you come into the house, I'll go to Jiajia's house for two days, and I'll bring her back on the fifth day of the new year." Zhang Song sat in the car and said to Zhang's father and mother who were standing at the door.

Mother Zhang instructed uneasily: "When you go to Jiajia's house, behave well, don't let Jiajia's parents have any opinions about you." ”

"Got it, Mom, don't worry, I'm leaving." Zhang Song waved his hand, closed the car window, drove away from the villa, and drove all the way to Qing'an.

At noon, Zhang Song arrived at Song Jia's house, Song's father and Song mother had already known that Zhang Song was coming, and they had already prepared wine and food at home.

"Come, come into the house and rest for a while, if you are hungry or not, you will eat immediately." After Zhang Song carried his things upstairs, Song's mother said with a smile on her face.

"Auntie, I still have some things in the car, I'll go downstairs and get them." Zhang Song was already accustomed to Song's mother's enthusiasm, so he said with a smile.

"Don't worry, I'm going to get it after eating, Komatsu, you can have a drink with me later." Father Song said beside him.

"Okay, just listen to my uncle." Zhang Song nodded, 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.

"Hmm." Zhang Song is also very happy, he hasn't seen Du Song Jia in the past few days, although the two have to make video calls every day, but after seeing the real person, he found that he still misses him very much.

Zhang Song and Song Jia chatted with Song's father for a while, Song's mother's meal was ready, in order to entertain Zhang Song, Song's mother made a big table of good dishes, Zhang Song accompanied Song's father to drink a few glasses of wine, and drank the golden wine that Zhang Song brought over.

At night, Zhang Song and Song Jia lay on the bed, and after a lingering moment, the two fell asleep.

Zhang Song stayed at Song Jia's house for two days. In the fifth day of the new year, he returned to Songjiang with Song Jia, and in the past two days, Song's father and Song mother took Song Jia and Zhang Song to several relatives, so that Zhang Song showed his face in front of relatives and friends.

Zhang's father and mother were very happy to see Zhang Song and Song Jia coming back, and Zhang's mother took Song Jia's hand and talked for a while. It's like they haven't seen each other for a long time, and when Song Jia handed over the gift she brought to Song's mother, Song's mother was even happier in her heart.

"Mom, let's talk, I'll go to the cellar and have a look." Zhang Song saw that Zhang's mother and Song Jia were chatting warmly, and said to them.

After entering the wine cellar, Zhang Song did not stay here, and directly entered the Aoki Cave Heaven, and he did not enter the Aoki Cave Heaven for several days. Zhang Song came in to take a look.

As soon as he entered the Aoki Cave, the Qilin ran down from the Aoki Mother Tree, biting Zhang Song's clothes and dragging him towards the thick fog.

"What are you doing, Kirin? If you let me go, can't I just go with you? The unicorn's mouth was full of sharp teeth, which tore Zhang Song's clothes, and Zhang Song said helplessly.

"Roar ......." Qilin listened to Zhang Song's words and loosened Zhang Song's clothes. Shouted at him twice, then led the way. Let Zhang Song follow him.

Zhang Song tidied up his clothes, and the two cuts on his clothes could only be regarded as if he hadn't seen them, and walked in the direction of the dense fog after the unicorn.

"I was looking at this, 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 new land had been carved out by the unicorns. There are about more than 100 square meters, which is several times larger than the last time Zhang Song came over.

"Roar ......." The unicorn yelled a few times again, and came over to bite Zhang Song's clothes again.

"Okay, what else is there to see, I'll go with you?" Zhang Song hurriedly dodged. Follow the Kirin inside.

Walking to the side of the dense fog, Zhang Song took a closer look, there was a big pit under the dense fog, two or three meters deep, half of it was on the side of the Aoki Cave Sky, and half was in the dense fog, it turned out that this was what the Qilin wanted Zhang Song to see.

"Kirin, this is after you absorbed the dense fog." Zhang Song squatted down and asked Qilin in surprise.

The unicorn shook its big head and roared into the pit, Zhang Song didn't know the intention of the unicorn, so he could only watch.

After a while, more than a dozen and twenty centimeters long, pitch-black as ink, and as if they were earthworms, crawled out of the pit.

"What is this? Could it be that it hatched from the more than a dozen black eggs a few days ago? Zhang Song was startled and couldn't help but be surprised. Qilin nodded beside him, indicating that Zhang Song was right.

When they crawled to Zhang Song's side, Zhang Song saw what they were, in the information in his mind, this kind of thing is called the Earth Dragon, which is a kind of earthworm-like thing, which is a kind of spirit animal, but they have no attack ability, but their use cannot be underestimated.

The earth dragon has two abilities, the first is to turn the ground, in the past, the owner of the Aoki Cave Heaven used the earth dragon to turn the ground, and the ground turned out is softer, and everything is planted.

The second ability of the earth dragon is to excavate, the earth dragon can swallow the soil, an earth dragon can swallow more than dozens of times the volume of its body every day, and after the earth dragon swallows the soil, it can also spit out a kind of thing, called dragon glue, this kind of thing is like cement, can bond the soil, very strong, in the past, the owner of the green wood cave used this dragon glue to build various houses, cellars and other buildings.

This is all the uses that Zhang Song understands about the earth dragon, but for Zhang Song, the two uses of these earth dragons are of little use to him, and he can only keep them as pets.

Zhang Song doesn't want to plant anything else in the Aoki Cave now, the ability of the earth dragon to turn the ground is not used, and the dragon glue spit out by the earth dragon is not very useful to Zhang Song, now the house is built with reinforced concrete, who will use such a thing as dragon glue, and even if Zhang Song wants to build something, he doesn't dare to take out something like the earth dragon.

"Are these two abilities really useless? If....... Zhang Song suddenly had an idea in his heart, but it flashed, and then Zhang Song shook his head, squatted down and looked carefully at the earth dragon at his feet.

After Zhang Song jumped into the pit, this pit is two or three meters deep, about four or five meters long, has entered the dense fog, just now when he saw this situation, Zhang Song was very surprised in his heart, it turned out that the dense fog only covered the ground, not the ground.

However, Zhang Song then thought that when a part of the pond was first revealed, he also tried, but he couldn't enter the other half of the pond through the bottom of the guò water, and the middle of the pond was separated by a thick fog, but now the earth dragon can dig the pit into the ground of the dense fog, which made Zhang Song a little puzzled, I don't know if it has something to do with the earth dragon, or because of the difference between the land and the spiritual water.

After thinking about it, Zhang Song gave up thinking about this problem, there are too many problems in the Aoki Cave Heaven, so that Zhang Song can't understand, if he wants to understand every question, Zhang Song has to die of worry. (To be continued......)
