"Look, my lord!" said Snoopy, opening his mouth, and suddenly there was a metallic sound from his mouth, which was pleasant and loud, like the chirping of thousands of birds.

Guan Xichen's eyes widened, and he saw that there were a lot of white lightning trembling in Snoopy's mouth, like small silver snakes.

"Whew!!" Snoopy opened his mouth and spit lightly. Suddenly, lightning burst out of its mouth, and the lightning was as many as silver birds, chirping and fluttering, towards the opposite mountain.

"Boom!!" the lightning birds struck the mountain, and the mountain collapsed in an instant.

"Damn! It's so powerful! It's really powerful! But ...... Don't make such a big move next time, if you are discovered by those special forces, it will be over!" Guan Xichen was both happy and worried.

"Don't worry, my lord! Nuya, restore the mountain peaks on the other side!" Snoopy turned to look at Snuya.

Snuya smiled and nodded, and then took out a jade bottle from his cuff, and a wicker was inserted in the jade bottle, just like the jade bottle held in the hand of Guanyin Bodhisattva. Then Snoya pinched the wicker with her slender hand, dipped it in a little water, and flung it towards the opposite peak.

With a bang, a holy light shrouded the ruins opposite, and the mountain peak was restored to its original state at once.

"That's very good!Quickly teach me how to use this trick!?" Guan Xichen nodded in satisfaction, and then looked at Snoopy.

Snoopy then spoke, "This trick is called 'Thunder Bird', and it is produced by the rapid agitation of the tongue in the mouth and the flow of spiritual energy in the mouth. Let's put it simply, the lord must know how the lightning in this atmosphere is formed!"

"I don't know how lightning is formed!" Guan Xichen stuck out his dog's tongue.

"Well, then I'll explain it to my lord," said Snoopy, "lightning is a natural phenomenon, usually a storm cloud (cumulonimbus) that produces an electric charge, with yin electricity at the bottom and yang electricity at the top, and also a yang charge on the ground, which moves with the clouds like a shadow. Positive and negative charges attract each other, but air is not a good conductor. The positive charge runs to the tops of trees, hills, tall buildings, and even the human body in an attempt to meet the negatively charged clouds, and the negatively charged branch-like antennae stretch downward, reaching closer to the ground as they go downward. Finally, the positive and negative charges finally overcome the air barrier and connect. A huge electric current surged from the ground to the clouds along a conductive airway, producing a bright and dazzling flash. Hey, anyway, there are many reasons for the formation, and I'll introduce you to the most common one, can you understand?"

"I don't understand!" Guan Xichen shook the dog's head.

"Okay! It doesn't matter! In short, let the aura in your mouth contain water vapor to form a positive and negative charge, and then form a lightning bolt in your mouth, and finally erupt this lightning! It's that simple! You don't need any formulas or seals!" Snoopy continued, "It's mainly by the stirring of the tongue and the control of the aura!

Guan Xichen didn't seem to understand, nodded, and then opened his mouth, his tongue constantly flicking in his mouth.

"Ahh

"The way the lord's tongue stirs is wrong, why don't I teach him!" Shi Nuya looked at Xi Chen's appearance of shaking his tongue hard, and he couldn't bear it slightly.

"How do you teach him?" Snoopy asked.

"Of course, use my tongue to help his tongue stir!" said Snoya.

"You mean tongue kissing?" Snoopy opened his mouth nervously.

"Yes!" said Snoya.

"No, no, no!" Snoopy hurriedly shook his hand, blocked in front of Snoyah, and looked at Guan Xichen, "Lord, why don't I use my tongue to stir your tongue!?"

"Poof!!" Guan Xichen suddenly spit out a mouthful of blood, "!

"Why did you vomit blood, did it matter?" asked Snoopy.

"I don't know, my chest is uncomfortable!" Guan Xichen said.

"It seems that it must be caused by the lack of qi and blood, and the transmission of spiritual energy is not right! The lord tried to sink into the dantian, felt the warm air flow in his dantian, and then let it move slowly upwards until it was poured into the heart, and then transmitted into the blood through the heart, and finally fused with the air in the lungs, releasing the aura, and then spewing out from the trachea, so that the aura can come out of your mouth! At this time, if you quickly stir your tongue, you will definitely be able to produce lightning!"

Guan Xichen acted according to Snoopy's words, and sure enough, a warm current entered the heart along his meridians, and then transmitted to the lungs, reached the trachea, and entered the mouth.

"Click!!Click!!" Guan Xichen opened his mouth, and the red aura overflowed his mouth, and red lightning suddenly formed. The lightning exploded in Guan Xichen's mouth, instantly blowing Guan Zhong's mouth open, and blood flowed.

"Ah, lord, you have to be careful!Nuya, quickly heal the lord!" Snoopy said hurriedly when he saw that Guan Xichen's mouth was full of blood.

"No...... No...... Didn't you say that it would be good for me to heal myself? This little injury is not in the way, only if I heal myself, my mouth will know what is wrong!" Guan Xichen shook his head, stopped Shi Nuya who was walking towards him, spit out a few mouthfuls of blood mixed with saliva, and then concentrated on urging the aura in his body.

"Hmm...... Lord, I was deeply touched by your perseverance and excellent quality! I didn't expect you to be such a strong single dog!" After listening to Guan Xichen's words, Snoopy burst into tears.

Shi Nuya was also moved, wiping the tears from the corners of her eyes slightly.

Later, after tireless study, Guan Xichen finally learned the skill of "Thunder Bird" a month later. Of course, the "Thunder Bird" he cast and Snoopy's performance are simply worlds apart, after all, Snoopy is a dog fairy, and Guan Xichen is just a period of spiritual silence. The "Thunder Bird" cast by Guan Xichen was only able to bombard a small crater on the mountain. But this is already contentment for him, and he knows that he can not accumulate a thousand miles without accumulating steps.

By the way, I have forgotten to say that Guan Xichen's hair color is actually earthy yellow, the same color as the earth dogs in the countryside, ordinary and unremarkable, and the appearance looks a little silly.

Guan Xichen burned all the hair on his whole body when he was promoted, but this month it has grown again, and the fine yellow fluff is like the yellow hair of a chick or duckling that has just been born, but it is slightly better than the previous soil dog's coat color.

Every day, Guan Xichen will breathe in cultivation, absorb the aura of heaven and earth, and at the same time constantly exercise his tongue, and practice the technique of 'Thunder Flying Bird' proficiently.

In order to change back into a human form, Guan Xichen did not complain of hardship, did not call him tired, forgot to sleep and eat, and continued to cultivate, just hoping that he could quickly change back into human form.

After the last pill incident, Guan Xichen didn't dare to ask Snoopy for the kind of pill to take to improve his cultivation. Not only because his body couldn't bear it, but Snoopy also told him that it would take a long time to stabilize his strength in this way, and the effect was far less powerful than his own step-by-step cultivation and growth.

So, in normal times, Snoopy asked Snoopy to mix some spiritual fluid that warms his body in the big water tank, and let him soak in Xichen every day.

As for what to eat, the two dog fairies waved their hands and there was roasted rabbit meat, which Guan Xichen didn't have to worry about. Under the care of these two assistants, he also grew up rapidly, and soon had a basic understanding of the way of cultivating immortals.

Just as Guan Xichen was happily cultivating, on this day, Snoopy looked at him with a heavy face and said to him, "Lord, you can't just focus on cultivation! Don't forget your mission!"
