With this limitation, the reason why song Tianxuan wanted to practice Wulei palm was that he paid attention to the palm technique.

According to the attributes of the five elements, the five thunder palm can be divided into five palm techniques: gold, wood, water, fire and earth. Moreover, the power of the released palm thunder is not bad, and more importantly, it is pure.

However, no matter what kind of palm thunder is, it can only be destroyed on the basis of metallic inner Qi.

Song Tianxuan changed the fire thunder palm a little, so that he could release the fire thunder even with his original internal Qi, but it could also be used to temporarily raise the temperature of the fire.

When his cultivation reached the later stage of inner Qi, he also learned the corresponding moves. Song Tianxuan had reached the condition of entering the inner gate from the outer gate.

Just need someone to recommend, this day he took some usual refining pills to find Du Shan.

"Master, these pills are made by disciples. Please accept them!", Song Tianxuan stood on one side respectfully, handed up the porcelain bottle with pills, waiting for Du Shan to take the initiative to ask.

Sure enough, after Du Shan checked, he was surprised: "well, in less than a month, you have made so many Chinese elixirs. This talent is amazing. Is there another senior pharmacist in our dizang sect?"

Song Tianxuan said with a smile: "to tell you the truth, in addition to practicing medicine, the disciples have not forgotten the master's instruction and practiced martial arts diligently. Now they have reached the late stage of internal Qi cultivation, and they have also learned fire thunder palm!"

As he spoke, song Tianxuan raised his left hand. With the movement of internal Qi, red thunder flashed through his fingertips. Although he looked very small, he had a strong heat, and his power was absolutely good.

Seeing this, Du Shan slapped the table and said with pride, "well, I'm worthy of being selected. I'm not only gifted in medicine making, but also outstanding in martial arts. I almost caught up with myself. Ha ha ha!"

Well!

Song Tianxuan was speechless for a while. Who were you then? You don't know who I was!

However, at the age of only 50, he has already reached the realm of imperial air. There should be some talent.

At this time, Du Shan was in the ascendant. Naturally, song Tianxuan could only flatter him with one or two words: "it turns out that master's talent is stronger than his disciples. No wonder you can become the master elder!"

He didn't mention the word "outer door" on purpose. After all, although the master elder is more noble than the general elder, he is only the strongest one in the outer door.

Du Shan was very helpful to song Tianxuan's flattery, and burst out a burst of forthright smile. When the laughter stopped, he suddenly looked puzzled: "ah, no, you usually keep a low profile. Why do you take the initiative to show your strength this time, and you talk a lot more, don't you?"

Song Tianxuan was waiting for this opportunity. He glanced at the direction of the inner door and looked at Du Shan with a smile. As long as he was not a fool, he could understand what he meant.

Du Shan immediately understood. He patted his thigh and said frankly, "ha ha, I'm confused. Now that you have reached the late stage of internal Qi, you have met the requirements of promoting the external disciple of the dizang sect. As a teacher, I'll write a letter of recommendation for you now!"

With a wave of Du Shan's hand, paper and pen appeared on the table. He thought for a moment, then wrote down a few lines of big words, and finally handed the letter to song Tianxuan: "take this letter of recommendation to elder Xing in the inner gate to go through the formalities, and then come back to me!"

Song Tianxuan was stunned there. He asked, "is that right? Is it too simple? "

Du Shanli naturally said: "it's so simple. You are my registered disciple. Even if you go from the outside door to the inside door, you can't just change your master and leave me alone."

Of course, song Tianxuan didn't mean that. He didn't know how to explain it.

At this time, Du Shan gave another mysterious smile: "Hey, in fact, the inner disciples are similar to the outer disciples, but they allocate more resources every month. If they don't get the approval of the sect leader, they can't practice the art of assassination!"

After hearing Du Shan's explanation, song Tianxuan was relieved.

It turns out that only the inner disciples who are trusted by qiusandao can practice this skill. It seems that even in dizang, there are not many people who can master the skill of assassination.

In addition to Qiushuang, how many of her followers have been recognized by qiusandao?

"The disciple will go back soon!"

Song Tianxuan leaves, goes through the streets and alleys into the inner city, inquires all the way, and soon finds Xing Changlao's residence.

It looks like a very ordinary house, but in terms of area, it's not even as big as Dushan's.

At this time, the courtyard was empty and calm. Looking inside, there was a row of wooden houses with all the doors closed.

Song Tianxuan is hesitating whether to go in directly. A voice like a ghost suddenly rings from behind him: "what are you doing standing at my door stealthily?"

Song Tianxuan's brow is slightly wrinkled. His cultivation has been in the late period of internal Qi, but he has no idea when the man appeared behind him.

Even if the other side uses the body method, why does he not even reveal his breath? It's incredible.

He looked back and saw a haggard black robed old man standing there. His two deeply sunken eyes were lifeless, but they felt like an abyss.

He subconsciously used his power to resist, which was not forced by the other party's cold momentum to kneel down directly.

"Disciple song Tianxuan, meet Mr. Xing!" Since the other party said that this is his door, that person must be Xing Changlao, song Tianxuan bowed his hand to worship.

Like a ghost, Mr. Xing glanced up and down at Song Tianxuan. Finally, he had some expression in his dim eyes. He nodded and said, "you are Du Shan's Apprentice. Take out the letter of recommendation!"

Song Tianxuan hurriedly took out the letter of recommendation, and the other party grabbed it, glanced at it, nodded again and said, "it's Du Shan's handwriting, and then!"

A token flies over. Song Tianxuan reaches for it and uses some power secretly. Unexpectedly, the token is light and has no hidden power, which makes him nervous for nothing.

Whoo!

A breeze blew by, and Xing Changlao, who was standing in front of song Tianxuan, disappeared.

After a pause, he suddenly turned back, only to see that the door of the old house of Xing Chang had been closed quietly. It seemed that the other party had gone home.

Look at the token as like as two peas of the disciples of the Tibetan gate, which are just like the token of the disciples.

All the way back to the main hall of the outer gate, after seeing Du Shan, song Tianxuan told his previous experience all over again.

Finally, he emphatically described the strange temperament of Xing Changlao, who was half human and half ghost, and looked at Du Shan blankly.
