Seven days! For seven days, Tong Xin stayed in the wooden house and never went out, and at this time he was at the most critical moment to build a flying machine, "Please, this time it must be successful!" "Childlike heart is constantly blessed, there are a lot of black carbon parts next to him, it is enough to see that Childlike does not know how many times he has failed, this is the last chance to experiment, he has no extra materials.

Zizizi......

The aircraft suddenly emitted a deep blue light, which fused with the childlike blood, constantly generating violent fluctuations, and finally slowly subsided.

"It's done, it's done!" Tong Xin jumped up happily, this flying machine took him too much effort, for seven days without sleeping, eating, let alone bathing, at this time his eyes were already full of bloodshots, and the head of the tense mind finally relaxed at this moment, and as soon as the person fell to the ground, he fell asleep directly.

I don't know how long later, there was a quick knock on the door.

Bang bang bang!

Bang bang bang!

Syllable! The house door was opened.

"It stinks!" It was Zhou Wangxian who walked in, she knocked on the door outside for a long time without response, so she had to break down the door, and as soon as she came in, she smelled a foul smell, and in front of her was the childlike heart lying on the ground.

Zhou Wangxian hurriedly went over and shook his childlike heart, but found that he still didn't react.

"He's not going to be dead." Zhou Wangxian sat on the ground, his face was full of melancholy, if the childlike heart was really dead, she would definitely be punished, before Zhou Tianshi specially told her to take care of the child's diet and daily life these days, but every time he came to deliver food, he found a reason to send him away, and he was very impatient, and he was angry, and he didn't send him food for several days.

"Alas, it's quite pitiful to see you, if you die in the wilderness, you probably will be eaten by those animals, but fortunately you met me." Zhou Wangxian ran out of the village with his childlike heart on his back, and took a shovel when he left.

"It's here, there are mountains, rivers and rivers, it's a nice place." After Zhou Wangxian drew the location, he picked up the shovel and dug it up.

After working for more than half an hour, Zhou Wangxian finally dug a pit more than 1 meter high, then threw his childlike innocence into it, bowed three times, and began to bury the soil.

"This chicken leg is really good, and this sandwich, let's chirp ......"

"I'm sorry, this sandwich has gone bad!" Childlike spit out the "sandwich", slowly opened his eyes, and saw the dazzling sunlight constantly shining on him, from time to time there was loess falling from the sky, and he also saw a hazy figure swaying, as if dancing, childlike was in a trance, "I'm not dreaming again." Then he closed his eyes again.

Rustling!

Tong Xin seemed to hear the sound of shoveling sand, some doubts, so he stood up, and at first glance, he saw Zhou Wangxian digging with his head down with a shovel and his head down, only to see that she threw the dug loess in the place where Tong Xin had just laid.

"I, Zhou Wangxian, what are you doing here?" Tong Xin finally understood that he was not dreaming just now, but it was real, and looking at Zhou Wangxian's actions, it seemed that he wanted to bury himself.

Zhou Wangxian heard the voice, looked up, and saw that Tong Xin was actually standing in front of her at this moment.

"Ahh

"Corpse!" Zhou Wangxian didn't wait for the childlike to explain, picked up the shovel and shot it at the child's head.

......

"Right...... I'm sorry. Zhou Wangxian knelt on the floor, and the person in front of him was none other than Zhou Tianshi.

Zhou Tianshi snorted coldly and said solemnly: "You haven't done a good job in any of the things I told you, punish you for facing the wall here for three days, and reflect well." ”

Zhou Tianshi turned his head to look at Tong Xin and shook his head, "You don't have to work too hard, you are still young, and your body is the most important." ”

The childlike chick nodded like rice, and sat in the position very dignified, in stark contrast to Zhou Wangxian, Zhou Tianshi looked at Zhou Wangxian again, and sighed again and again, if her granddaughter had a childlike attitude, he would not be so worried.

When she was a child, Zhou Wangxian was always taken by her parents, and when she was three years old, her parents died when they went out on a mission, so she could only take her granddaughter by herself, but she was too busy with her work and did not discipline Zhou Wangxian in place, which would cause her to become such a frizzy character.

Tong Xin felt Zhou Tianshi's mood at this time, so he took the initiative to say: "It's not to blame Zhou Wangxian, she did come to deliver food to me, but I was too busy at the time, so I refused her." ”

Tong Xin pulled out his cuffs and took out a small blue ball: "This is the research result of my past few days, please take a look at it." ”

Zhou Tianshi took the childlike ball and observed it for a while, only the pattern on the ball was a little better, and he didn't find anything special, so he gave it back to the childlike heart, wanting to know his thoughts.

Childlike heart grabbed the blue ball, urged its own mana to guide into the ball, suddenly blue light flashed, the ball began to change and reorganize, and finally became a scimitar, childlike put the "scimitar" behind, I don't know what to say in my mouth, this scimitar flew up with childlike innocence.

The childlike heart flies outside the gate, opens the gate, and flies into the sky, flying higher and higher.

Zhou Tianshi hurriedly shouted, "Summon! Skywalker Warframe. ”

The fiery red armor instantly pierced Zhou Tianshi's body, and with a slight leap, he flew to a height of 100 meters, and the thrusters behind the Tianxing armor continued to emit flames to help him fly, rushing towards the childlike heart, and the two of them were like a race, soaring in the sky at will.

5000 meters!

10,000 meters!

Childlike did not continue to stop, still flying upward, but at this time he also put on the battle armor, now he has reached the stratosphere in the sky, the body can not withstand it, only the armor can withstand the impact of the air current, when it reaches 11000 meters, the childlike heart stopped and continued to fly upward, and then looked down, but did not see the figure of Zhou Tianshi, so he flew back, and finally saw Zhou Tianshi at 6000 meters.

Zhou Tianshi looked at the armor worn by Tong Xin in surprise, but he didn't say anything, after connecting Tong Xin's address book, the two flew back to the original road, along the way, Tong Xin was talking about the principles and methods of making this flying machine, and the derived functions, when he heard Tong Xin say that this flying machine can be upgraded again, he was shocked again.

After landing safely, the two returned to the wooden house, and Tong Xin put away the flying machine and sat aside, quietly waiting for Zhou Tianshi's assessment results.

Zhou Tianshi pondered for a while, and finally spoke: "The flying machine you made is very good, and you have passed the assessment target, just come to the wooden house on time tomorrow morning." ”
