Despite his resentment towards Bobo, Wu Ge still brought a bag of candy to Bobo the next day.

They stayed together at Lu's small house. The small house is about to be completed, and there is only a little problem with the interior decoration. Xiaoxiao and Cheng Yingxia haven't chosen what materials to use yet, so Wu Ge has rarely been a little idle in the past two days.

"Why did you eat so fast?" Wu Ge accused.

Bobo looked down at the bag.

"Mud said, pout me. ”

Although he was quite jealous of Wu Ge, Bobo still leaned forward and made a gesture to protect his food.

"Stupid monkey. Wu Ge scolded, reaching out and pulling out a lollipop from the bag and peeling off the package. Bobo muttered dissatisfied, but didn't dare to move.

"Of course you're chewing fast. Look at me......" Wu Ge put the candy in his mouth, sucked it a few times, and then took it out and handed it to Bobo, "It's going to take a long time to eat this way, understand?"

Bobo took the candy and looked at it for a long time, as if to think about whether it was hygienic to do so. Eventually, though, it shoved the sugar into its mouth.

"Click. ”

......

Wu Ge glared at Bobo.

"I don't live there. Bobo explained, as he continued to move his jaw serenely.

"Sooner or later, this dead monkey will eat me poor. Wu Ge thought with a gloomy face.

But he didn't want to worry about it now, he had more important things to deal with.

Yesterday's duel with Bobo benefited Wu Ge a lot, not only did the flow of true qi become proficient and smooth, and the qi climbing technique also advanced, but more importantly, after observing Bobo's flight with his own eyes, Wu Ge had a further understanding of flying. He now felt vaguely aware that he had glimpsed the secret of flight.

Bobo's spells are flawed - he's just a monkey after all. Not only did it not fly high enough, it was crooked, and it moved so much that it was always full of dust and leaves. The same is true for Wu Ge's (including other immortals)'s Qi Climbing Technique, but there is still a slight difference. Wu Ge observed very carefully - the Qi Climbing technique seemed to have a downward force, and if it was close to the ground, light objects such as dust and leaves would line up in both directions and fly upwards at a limited height, while Bobo's flying technique would always be the case no matter how high they were above the ground, and the dust leaves would fly straight upwards as if they were receiving an upward suction. If the flyer remains in the same position in the vertical direction, they will continue to fly under the caster's feet, as happened yesterday when the wave landed...... A true immortal would never be so muddy when flying, but it was the flaws of Bobo Flying that gave Wu Ge an important revelation.

This secret is about to come out, but there is always such a layer apart. Wu Ge's eyebrows were furrowed, his eyes were straight, and there were words in his mouth...... Fortunately, he is now in the fairy world, otherwise his mother doesn't know how much wronged he will have to.

Of course, he could ask Bobo directly, and Bobo would tell him the spell, but that would be pointless.

Gravity. The word suddenly jumped into Wu Ge's mind. Why can't people fly? Because of gravity. The master said that the secret of flight is not complicated, it is in the textbooks of middle school. Bobo's flying spell may seem to exert an attraction on objects on the ground, but if it were to be said the other way around......

Wu Ge stood up and instantly entered a realm of forgetting about things and me. His Celestial Eye Technique opened, and he searched the space carefully......

Gravity, of course, is formless and colorless, not visible to the naked eye, nor can it be seen by the celestial eye. But gravity acts on all things, including qi, and can be observed indirectly by those who have intentions......

He saw it! The thick aura of the fairy realm was as soft as mist, and it seemed to have no weight, lingering and floating freely. But their movement follows certain laws, and in addition to the wind and their interaction with each other, there is a strong, stable, regular force at its disposal......

Wu Ge realized, and the Yongquan acupoint in the heart of his feet began to beat slightly, which in turn drove the entire meridian to become active. The true qi in the body is like a subordinate who is good at figuring out the mind of the boss, and begins to act independently. Wu Ge carefully observed and controlled the operation of True Qi. He didn't know the spell of flying, but he was confident that he could figure it out, and it wouldn't take long......

"Uhhhhhh ”

Wu Ge rushed towards the house like an arrow, slamming into the wall with a "bang". Its momentum was so fierce that Bobo threw the candy in his hand and jumped up to the roof with a "poof".

"Mud catches?"

Bobo crouched on the roof, and asked with a palpitating probe.

"Uh, nothing...... Practice. Wu Ge replied embarrassedly.

"......?" Bobo scratched his head in confusion.

"What work?" it asked.

Dead monkey, that pot doesn't open that pot.

"What are you doing?" Wu Ge said with a straight face, "eat your sugar well." ”

Bobo looked at the sugar scattered on the ground and jumped off the roof.

"The disaster sticky gong first greets, and it is scary. It swaggered.

Wu Ge glared at Bobo, feeling the urge to use the magic weapon...... But the joy of relative success is nothing. He knew in his heart that he had not "crashed" into the house, but "fallen" onto it - he had just managed to reverse the direction of the gravitational field by ninety degrees!

Ecstasy surrounds the body, like every cell has a sugar cube in its mouth, and it is sweet all over the body. Think about it, it actually changed the gravitational field of the earth! Although it is only limited to a small range, it can be called against the sky. And most importantly: it shows that his guess was correct, and flying is all about. Just twist the direction of the gravitational field by 90 degrees......

Indeed, the reason why the gods can fly is the result of changing the direction of the earth's gravitational field. Of course, they can only do this on a small scale, and if they want to change the gravitational field of the entire earth, even immortals like Chi Songzi who have achieved "secondary ascension" can't do it. The theory of this spell is difficult to explain, and there is a constant debate in the spiritual circles. However, it is certain that changing the direction of the force field is the third most difficult spell, the first two being the change of time and space structure, respectively.

Wu Ge regrouped and entered the realm of selflessness again. He carefully observed, carefully adjusting the operation of his true qi. He believed that he would succeed this time -- that would be a breakthrough and a milestone in his immortal cultivation career. This breakthrough is so important and so close at hand...... God, he's a little dizzy.

Bobo raised his head, looked at Wu Ge who was flying towards the sky, snorted disdainfully, and reached out to take the twenty-second candy of the day.

Wu Ge opened his eyes and saw the thin vapor - that is, the clouds - speeding past his eyes. He looked around suspiciously......

He's flying! Definitely flying, and this height is definitely not something that can be achieved by Qi Climbing. He had already flown into the clouds, the moisture in front of him was getting thicker, his clothes were already wet, and he felt a chill that was getting heavier and heavier. But none of this stopped him from enjoying the joy of flying and the excitement of finally achieving a breakthrough after all the odds.

What's cold? His head is so hot right now!

The only problem is: Wu Ge's body doesn't think it's flying upwards, on the contrary, it thinks it's "falling down." It's easy to explain the feeling that the gravitational field is turned upside down. Wu Ge's brain didn't understand this a little bit (no wonder it felt dizzy just now). Despite its best efforts to convince its body that nothing had changed, it was still the boss as usual, occupying the high ground of the human system - in other words: they still maintained their normal position above their heads and feet - but the blood poured desperately into the brain regardless of its rhetoric.

This kind of "falling upwards and downwards" is quite uncomfortable...... It was only now that Wu Ge finally understood that his vertigo was not just caused by excitement. Moreover, the pillar of dust that appeared at his feet (or rather on his feet?) also made him sober up a little - it seemed that his flying skills were not so perfect, although the altitude was far higher than Bobo, but he did not solve the shortcomings of Bobo's flying skills.

"This may be because the gods can limit the spell to one point, and he and Bobo can only control it in one line. Wu Ge thought to himself. However, he felt that this should not be a difficult problem to solve, and in time, he would definitely be able to reach the level of an immortal.

Then, the really hard problem slowly floated up from under the water like a grinning crocodile...... How can he get back?

He is now flying upwards (or downwards) at a slower rate, which is probably the reason why gravity weakens when he moves away from Earth. But that doesn't change the fact that he's getting farther and farther away from Earth.

In the horror, he thought of the words of Lu Xiao's novel: "...... Flying upwards with all his might, the stars are still so far away for half a day. In the end, he couldn't breathe, so he had to come down......" Lu Xiaoxiao could still come down when he "had to come down", but he didn't know how to "get down" at all.
