After eating the barbecue, Wu Dong asked the Liu sisters to enter the cave to rest, while he himself sat cross-legged at the mouth of the cave, deciding to practice the internal strength of the Guiyi True Sutra at night and assume the duty of vigil!

Under the control of his mind, wisps of chaotic vitality gathered around Wu Dong from all around, gradually integrated into his body, and then penetrated into the meridians inside his body, running according to the practice route of the internal gong chapter of the Guiyi True Sutra, and were refined by him bit by bit. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

"Huh! I don't know when I will be able to refine the chaotic vitality in my body into chaotic true qi, and I don't know when I will be able to further transform it into chaotic true qi! "The chaotic vitality in his body can't be commanded by his arm, and if it is jerky between transportation, Wu Dong knows in his heart that the chaotic vitality absorbed from heaven and earth has not been completely controlled by himself!

According to the grading of the Unified True Sutra he created, the Yuan Qi is divided into three levels, one of which is the Yuan Qi that originally existed between heaven and earth, even if it enters the body meridians for refining, but it does not reach the level of complete control as commanded by the arm, it is still called Yuan Qi! At this time, the vitality in the body cannot be separated from the body, but when it is running in the body, it can increase the strength, strength, etc. of the body!

The second stage of the Yuan Qi, that is, is completely refined, completely controlled by oneself, when used as an arm, Wu Dong defines it as true qi, such as the acquired martial artist in the martial arts world When the innate martial artist advances to the innate one, the internal force is converted into the innate true qi! It's like the True Qi Wall formed by the True Qi separated from the body, the True Qi Shield, the True Qi Blade and the like!

The third stage of the vitality, Wu Dong called it Zhengang, that is, the product of the true qi after thousands of tempering, Zhengang is indestructible, defenseless, and has strange effects such as autonomous body protection.

Under Wu Dong's inner vision, he saw that the vitality absorbed from heaven and earth passed through the meridians and acupuncture points, and a part of the chaotic vitality was divided into three and precipitated in the upper, middle and lower three dantians, and the remaining chaotic vitality was absorbed by the five organs according to the attributes of the five elements......

Nothing happened all night, and in the early morning, the three continued on their way.

On the way, Liu Ying asked him from time to time about his origin and other questions, but she didn't know that her secret expression last night made Wu Dong feel a little estranged, as if there was destined to be an unfillable trench between them!

Although I always say in my heart, it is normal for Liu Ying to be wary of herself, and there is no need to care, but Wu Dong can't find that feeling of mutual trust, and it is inevitable that they are suspicious of each other, maybe he and she are just passers-by, and they don't know each other well enough!

It's always uncomfortable to be suspicious of others, especially the person who rescued it yourself, even if you didn't help immediately at that time, so that you suffered some small losses, but you saved your life!

The more I thought about it, the more upset I became, the surface did not move, there was a smile to deal with Liu Ying's questions, and from time to time I saw the cheering, bouncing, innocent Liu Huan, Wu Dong was a little relieved!

"Brother Wu, we've finally arrived!" Ten days later, Liu Huan happily pointed to Cloud City not far away and said to Wu Dongdao.

"Hmmm! It's so prosperous! Although the scale of the city's buildings is not as huge as Xuanwu City, the flow of people entering and leaving the city is more than three times more than that of Xuanwu City! Looking at the Cloud City in front of him, Wu Dong opened his mouth and praised.

After paying the entrance tax, the three of them entered through the city gate, and at a glance they saw a forest of shops and a lively scene.

"Brother Wu, although the scale of Cloud City is not comparable to Xuanwu City, the people who can live in Cloud City are much easier than the people in Xuanwu City!" Liu Ying said with a smile.

"yes!" Wu Dong nodded, but he didn't think so in his heart, if there were no people from Xuanwu City in front to block the invasion of the orcs, would this place be so prosperous? If Xuanwu City is broken, the prosperity here will be like a bubble!

The second daughter of the Liu family took Wu Dong to board the repulsion speed car in the city.

Wu Dong asked the second daughter curiously, "Why is there no flying car outside the city?" ”

"Brother Wu, the number of repulsion speeders is limited, most of them are in the hands of the imperial army, and the cost of repulsion speeds is expensive, and ordinary forces can't afford it at all, not to mention that the defense of the repulsion speeders is weak, and the maintenance costs are too high!" Liu Ying explained to him.

"If the defense is low, why not make it with high-strength materials?" Wu Dong asked puzzled.

"Brother Wu, the high-strength material, either the weight is too large, which seriously affects the speed of the repulsion speed, or the weight makes the flying car unable to take off, even if some high-strength materials are lighter, but the price is prohibitive!" Liu Ying tugged at Wu Dong's sleeve and explained in a low voice.

Seeing the strangers in the car around him, all looking at him with idiotic eyes, Wu Dong smiled awkwardly and stopped asking such common-sense questions.

"What are you laughing at? Wait for the uncle to have time to make a repulsive speed car made of alloy in the future, and blind your dog's eyes! Secretly scolding in his heart, he looked at the huge repulsion speeder, but he didn't know what it relied on to fly.

Driven by curiosity, Wu Dong used the power of his mind to scan the structure of the Repulsion Speed Car in detail, preparing to build a Repulsion Speed Car himself in the future.

It didn't take long for the repulsion car to take off in the air, and under the shroud of thoughts, Wu Dong imprinted all the repulsion speed car how to take off, such as flying after it.

"I see!" With a sharp turn of thought, Wu Dong already knew the operating principle of the Repulsion Flying Car, and its essence was similar to that of the Eight Veins Refining God of this world's martial artists.

"The primeval sages looked at the shape of the laws of heaven and earth, and presented the shapes of each law in a diagram, calling them primeval characters, and each primeval character with implied vitality has corresponding strange abilities...... The Eight Veins are channeled, that is, the vitality in the body is refined into primeval characters, so that the power of various laws can be brought out! ”

Recalling the content of the Eight Pulses in his mind, Wu Dong suddenly realized.

"Brother Wu, we're here!" Liu Huan gently pulled Wu Dong and reminded.

The three of them stepped off the repulsive speed car, walked for a while, and came to a mansion called the Yunwu Li family.

"Liu Ying, Miss Liu Huan!" When the four goalkeepers saw the sisters of the Liu family coming, they did not dare to slack off and bowed their heads.

"Uncle Li is not here?" Liu Ying asked the goalkeeper.

"The master is in the house, Young Master Li Hao is also there, the two young ladies and this son will wait in the living room first, I will go and report!" After one of the goalkeepers answered, he turned around and informed the old man and the young master.

"Three, please come with me!" Another goalkeeper led Wu Dong and a few people into the mansion.

Moments later, a middle-aged man and a teenager walked in from outside the living room.

"Uncle Li, Xiaoying almost won't see you again!" Liu Ying remembered the bumps in the road, and pulled the middle-aged man to cry.

"Uncle Li, Brother Li!" Liu Huan greeted in a low voice.

The middle-aged man surnamed Li asked about what happened to the second daughter of the Liu family on the road, and after comforting him, he remembered that there was a Wu Dong next to him who had been forgotten by himself and others, and smiled awkwardly: "Forgive me!" Excuse me! The old man only cares about comforting Xiaoying and Xiaohuan, snubbing the little brother, and thanks to the little brother for saving his life! ”

"Thank you, brother, for saving Xiaoying and Xiaohuan!" Li Hao said gratefully.

"The old gentleman is polite!" Wu Dong's words were quite respectful, and he was arrogant and did not climb the relationship.

"Hao'er! You take this little brother around, I haven't seen Xiaoying and them for a long time, I'll talk to them! The middle-aged man confessed to Li Hao.

"Yes, Father!" Li Hao responded, and then said to Wu Dong: "Brother Wu, I'll take you to the Li Mansion for a walk!" ”

After the meal, Wu Dong wanted to say goodbye, but the Li family's father and son and the Liu family's sisters repeatedly retained, and they stayed in the Li family for a few days one after another.

During this period, the Li family's father and son warmly entertained and kept them again and again, but thinking of his goal of entering this world, Wu Dong had no choice but to leave

Maybe it was because he insisted on leaving, or maybe it was some other reason, the Li family's father and son finally let him go that day, Wu Dong felt a little strange in his heart, but he didn't think about it.
