Late at night, in an open place on the top of Wudang Mountain.

"Haha." A loud laugh was heard. Xu Fei's eyes showed a look of ecstasy.

"I was finally able to sketch the secret pattern of this first paragraph in one go." For a month in a row, Xu Fei's efforts finally paid off, and a sense of accomplishment arose.

After outlining this secret pattern, this extremely complex secret pattern in Xu Fei's consciousness did not disappear, but slowly rotated in his consciousness, and as it rotated, its huge secret pattern gradually lit up, forming a huge and mysterious pattern.

Beautiful, vast, and spinning slowly, it is as dazzling as the Milky Way in the sky. As he expected, once the secret pattern was fully depicted, it would never be forgotten again.

"I just don't know what the effect is." Xu Fei thought about it, so he used his spiritual power to miniaturize this complex secret pattern and carved it on the one-foot-high stone on the side.

As soon as the secret pattern was completed, the stone actually emitted light, and the light of the secret pattern seeped into the void, and the countless energy particles in the air seemed to encounter a strong attraction, and they quickly rushed towards the stone, and the wind surged between heaven and earth for a while, and the wind howled.

A loud "boom" was heard. The stone couldn't withstand the impact of countless energy particles, and exploded directly, and the energy that gathered together suddenly lost its traction and scattered in all directions, and the violent wind almost lifted Xu Fei away.

Xu Fei couldn't help but be stunned when he saw such a scene, his eyesight and mental power were very strong, and he completely sensed that the energy particles in the vicinity just now seemed to be affected by the power of this secret pattern, and they all converged, and when the stone exploded, Xu Fei obviously felt that there was a surging ocean of energy particles in the distance converging here.

"This secret pattern has the effect of gathering energy." Xu Fei pondered for a moment and said, "What if this secret pattern is engraved on some machinery?" Doesn't that mean there will be a constant supply of energy? ”

"But the conversion and utilization rate of energy is also a problem." After all, this kind of furious energy cannot be used directly, it must be transformed.

Xu Fei's eyes suddenly lit up and said, "What if this secret pattern is engraved on the weapon?" ”

"Of course, you don't have to depict it too perfectly, leaving a small gap, just like a switch, excited under special circumstances, then you can instantly gather powerful energy, and you will definitely be able to exert great power when attacking with weapons."

At this time, Xu Fei remembered the scene of energy convergence just now, and shook his head secretly: "But I'm afraid ordinary metals can't withstand such majestic and violent energy." ”

"That's not right."

Xu Fei remembered the ability of the "Silver Core" at this time, the combination of the first stage of the secret pattern and the second stage of the secret pattern can purify energy, and the purity of the purified energy is extremely high, even higher than the purity of the energy he refined in "Furnace Fist".

"If I can sketch out the secret patterns of the first and second paragraphs, and combine them, I don't know if there will be the same energy-isolating effect on the 'silver core', if so, wouldn't it be able to solve the problem of energy transformation?"

Xu Fei was a little excited in his heart, and immediately began to study the secret pattern of the second stage.

The sky was slightly bright, and Xu Fei frowned. The secret pattern of this second paragraph is much more complicated than the heaviest one, and Xu Fei only sketched less than one-fiftieth of it in one night.

At first, Xu Fei planned to outline the secret pattern of the second paragraph alone, and when the second secret pattern can be completely outlined, it will be merged with the first secret pattern, so that it will be much easier.

However, after Xu Fei tried, he found that if he didn't sketch the first secret pattern, the second secret pattern could not be sketched at all, as if he wanted to paint a picture and didn't know where to start. Therefore, Xu Fei had no choice but to outline the secret pattern of the first paragraph, and after the first secret pattern was outlined, he was finally able to outline the second secret pattern.

Most of Xu Fei's energy overnight was actually spent in the first secret pattern, so the second secret pattern was very little.

"It seems that in order to completely depict all the secret patterns, you must outline all the secret patterns in one go."

Taking a deep breath, Xu Fei did not feel scared because of the huge project, but was full of fighting spirit. As soon as his body moved, Xu Fei went down the mountain after a few verticals.

After washing, Xu Fei greeted "Yunxia", so one person and one fox entered the forest.

"Calculate the time, today is the third day of August. I don't know what happened to my parents and sister. Don't think I'm dead. Don't be upset. ”

Xu Fei thought as he walked through the forest. Although there are unique cultivation conditions here, Xu Fei still wants to return to human society as soon as possible, even if he can't return to human society, he can report safety to his parents.

Isolated here, Xu Fei wanted to take the opportunity to escape from here several times, but he didn't have a chance. Half a month ago, he proposed that he go hunting with his students and hone his martial arts by the way, and Xiong Hei agreed.

Every time he came out to hunt, Xu Fei would use various methods to try to escape, but those fierce beasts remembered Xu Fei's smell, Xu Fei couldn't leave the position of five hundred meters beside them at all, once they left this position, they would appear in front of him, no way, the speed of these yellow-level fierce beasts was too fast.

For half a month, Xu Fei has been hunting in the Wudang Mountain Realm, fighting with red-level fierce beasts, from the difficult and embarrassing beginning, to now it is completely easy to kill red-level fierce beasts, and the progress is extremely amazing.

This time, Xu Fei wanted to go hunting outside Wudang Mountain, and by the way, he found an opportunity to escape, so he took "Yunxia" to the direction of Shennongjia.

After the ecological change of the earth, there are tall and dense forests everywhere. Xu Fei and the more than ten meters tall "Yunxia" walked in the forest, unable to cause any waves at all.

And Xu Fei instructed to let "Yunxia" restrain his breath.

"'Yunxia'! This time, let's find an orange-level beast to try our hand. Or the old rule, I'll do it, you watch, if I can't beat it, how about you help me again? ”

"Yunxia" didn't pay attention to Xu Fei.

At this time, Xu Fei suddenly exclaimed: "It's not good, I have a stomachache, I want to go to the toilet, you must not peep at me." ”

The one on the side lowered his head and squinted at Xu Fei, his "eyes" were full of disdain, as if to say, "Don't think I don't know what Xiao Jiujiu you're fighting." ”

Seeing that his thoughts were debunked, Xu Fei could only sigh that this fox was too smart.

He was used to the expression of "Yunxia", and he didn't mind, of course, even if he minded, it was useless. After walking a distance, Xu Fei said: "'Yunxia', you see that we are so familiar, can you let me ride you." 'Bailu' and 'Yuanxi' I've ridden them all, but I haven't ridden you, can't you be special as a member of the class? ”

"Yunxia" made a "sneering" sound, full of mockery, as if to say, "Even if I die, I won't let you ride." ”

Xu Fei has been grinding for more than half a month, and he is used to the rejection of "Yunxia".

"It's okay if you don't agree, and the amount of food will be halved in the future." Xu Feidao.

"Yunxia" snorted twice, now it already knows what a joke is, and it will not be like when Xu Fei threatened it and wanted to kill Xu Fei in a rage.

"Don't. I'm counting on you to continue to help me temper my body. I'm just kidding. Xu Fei has been able to fully understand the language of "Yunxia".

One person and one fox completely left the boundary of Wudang Mountain at this time.

After a moment, "Yunxia" stopped, and the fox's eyes showed a hint of coldness, and his gaze looked to the west.

Xu Fei knew that the prey had appeared, his spiritual power was emanated, and his spiritual tentacles spread in that direction, and in the jungle two thousand meters away, he found a giant fierce beast similar to a black bear eight meters high, which was gnawing on a red-level fierce beast under the big tree.

Xu Fei held the Miao knife in his hand, and disappeared into the forest in a few flashes.

Hiding in the forest, Xu Fei looked at the orange-level fierce beast, his eyes narrowed, at this time the fierce beast was eating, according to the reason, it was the best time to attack.

But Xu Fei's half-month combat experience told him that the vigilance of the fierce beast that was eating was the highest, because the fierce beast was not a human being, and it would often fight because of the food territory, and it was also necessary to guard against sudden attacks, so the fierce beast was very vigilant when eating. Only the moment when the beast has finished eating is the time when the vigilance is at its lowest.

The senses of the orange-level fierce beast were very keen, and at this time it seemed to sense Xu Fei's gaze, so it immediately raised its head and looked around, and its nose twitched.

"It's alarming."

Xu Fei immediately closed his eyes, lowered his breathing, used his mental power to isolate his own smell, and used his mental power to observe.

The black bear looked around for a moment, found nothing in its cold eyes, and was a little puzzled, so it relaxed and ate on the surface, but in fact began to be secretly vigilant.

"What a cunning!"

Xu Fei was stunned and smiled, the stronger he is, the more challenging it is.

After waiting for a moment, the beast finally swallowed the last bite of the flesh and let out a contented "hum".

Xu Fei stepped on the "Thunder Step" under his feet, and the whole person broke through the forest like lightning, and the Miao knife came out of its sheath, turned into a series of knife lights, and slashed down at the head of the black bear.

"The sword pierces the sky."
