Venerable Martial Emperor

Although he did not see it with his own eyes, he could still faintly feel the power that was being emitted from the Gray Essence Strength!    

"Let me see just how powerful this cultivation technique is!"    

With a low shout, he suddenly pushed out his palm and ruthlessly slammed it onto the big tree that was as thick as three or four people.    

With a loud explosive sound, only a flash of lightning could be seen. Thunder suddenly rose and lightning flew in all directions.    

Xu Feng's palm, and even his entire arm, sank deeply into the trunk of the tree.    

When he pulled his hand out, a palm print that was one or two feet deep suddenly appeared on the trunk of the big tree.    

However, just like that, although this martial art was a bit stronger than before, it still could not reach the point where it could be raised by a grade for no reason.    

Upon closer inspection, Xu Feng discovered some clues. He could only see that there were actually traces of Gray Essence Strength attached to the palm print of the large tree trunk.    

Under the effect of the Gray Essence Strength, that part of the tree trunk began to rapidly shrink at a speed visible to the naked eye. It became dry and withered, and its life force disappeared. It was as if the tree had already withered and died for a long time.    

Fortunately, the Gray Essence Strength had finally disappeared completely. However, at this moment, when he looked over, the area around the palm print of the five fingers had expanded to a withered area of over an inch.    

Xu Feng could not help but reach out and touch that withered area. With a 'Hua La' sound, that withered area collapsed in an instant. It was as if that part of the tree trunk had already withered and died for a thousand years, and had long turned into powder!    

"Alright... Amazing!"    

Xu Feng couldn't help but exclaim in his heart. His Flaming Palm could at most produce a foot deep palm print. However, with the enhancement of the Gray Essence Strength, it was able to produce a palm print that was nearly two feet deep. And around the palm print were the remaining Gray Essence Strength. He could actually slowly exert his power and devour all the life force of the trees around the palm print!    

It could be imagined that when this palm landed on a person's body, even if that person had a profound cultivation base, he would have to suffer a great deal of pain in order to resist these Gray Essence Strength!    

This Gray Essence Strength had indeed increased the power of the Flaming Palm by a grade. Currently, the Flaming Palm was at least a Low-grade Yellow Level martial art!    

"Hehe, with this Great Destruction Spell, I'm afraid my Shinra Seal will become even more powerful!"    

Xu Feng knew that his Shinra Seal had the attribute of cold and evil. Adding the Gray Essence Strength that could devour life force, it was like adding wings to a tiger. Not only could it raise one's grade to high Yellow Level, it was also one of the best amongst all high Yellow Level!    

"It's a pity that the Yuan energy of this Great Destruction Spell is too slow. It has been tempered for half an hour. Only after refining the Yuan energy of a single palm strike of the Flaming Palm could I refine enough Yuan energy for the Shinra Seal. I'm afraid I'll need half a day!"    

Xu Feng also quickly discovered this disadvantage.    

However, he also understood that if the speed of Great Destruction Spell tempering was the same as the speed of the Yuan energy seed tempering, then it definitely wouldn't be just a low Profound Level cultivation technique.    

Thus, he immediately sat down and started circulating the Great Destruction Spell, tempering his Yuan energy into a gray color.    

Half a day passed in the blink of an eye.    

When the afternoon arrived, Xu Feng finally managed to refine enough Gray Essence Strength to use the Shinra Seal once.    

He wasn't greedy. He knew that using the Shinra Seal with the help of the Gray Essence Strength could help him deal with most situations.    

Therefore, he stopped the refinement and walked down the mountain.    

At this moment, he was already a Middle Period of Martial Essence Stage, so he had to find a way to walk towards the Late Period of Martial Essence Stage.    

If he wanted to walk towards the Late Period of Martial Essence Stage, the Essence Soul Receiving Pill was an indispensable Medicine Pill. Although he had already cultivated three Thousand-year-old Essence Spirit Fruit, refining this Medicine Pill... Hence, he had to go to the Heavenly Mysteries Pavilion to buy some.    

Fortunately, he still had over five hundred Essence Crystal in the Purple Sun Martial Arts Secret Realm's Sikong Cave. He was an absolute rich man, so he did not have to worry about the cost of this little amount of Essence Crystal.    

Very quickly, he arrived at the Heavenly Mysteries Pavilion. The old man who was exchanging for Essence Crystal was still behind the counter, smiling as he looked at the customers that passed by.    

Xu Feng walked over and handed a list of spirit medicines to the old man. He said, "I want three portions of these spirit medicines!"    

" Oh? The Medicine Pill from last time has already been successfully refined? What Medicine Pill is he refining this time? " The old man smiled as he picked up the list and looked at it. Within his deep eyes, "It's actually the Essence Spirit Receiving Pill!"    

The old man immediately said the Medicine Pill that Xu Feng wanted to refine, causing Xu Feng's heart to involuntarily tremble. He couldn't help but take another look at this old man. The person who could see through the list of ingredients for the Essence Spirit Recruitment Pill... Xu Feng dared to say that there weren't more than ten of them in Profound Wind City!    

"Hehe... This old man is just making a random guess. You do not need to worry that I have ulterior motives!" When the old man saw the change in Xu Feng's expression, he smiled and said, "Let's get down to business. One portion of these spirit medicines costs fifteen Essence Crystal!"    

"What? So expensive?" Xu Feng couldn't help but raise his eyebrows. The last time he came to buy the Linlang Life Continuing Pill and the Golden Jade Qi Recovering Pill, the two types of herbs required for the Medicine Pill only cost three Essence Crystal.    

This time, the Essence Spirit Receiving Pill was just a Medicine Pill. A portion of the elixir actually required fifteen spirit stones, and the price was thirty times more expensive!    

When the old man saw Xu Feng's surprise, he continued to explain with a smile, "It's not that you don't know about this spirit medicine when you refine the Medicine Pill. With Qi Returning and Healing being the cheapest, it was the most valuable to be able to increase one's cultivation. All of the medicinal herbs on your list are extremely precious! "    

Xu Feng frowned. Indeed, herbs were divided into different categories, and it was the rarest and most valuable way to increase one's cultivation base. He also knew that the people of Celestial Mystery Tavern wouldn't cheat him.    

Fortunately, he did not write the Thousand-year-old Essence Spirit Fruit on it. Otherwise, the price of this set of herbs would have been raised to 30 Essence Crystal. Even if he had the price, the other party would not have the goods!    

When he thought of this, his eyebrows relaxed. He smiled and flipped his hand. He took out forty-five Essence Crystal and handed it to the old man. He said, "Please bring the medicinal ingredients over!"    

The old man's face involuntarily revealed a surprised expression when he saw the forty-five Essence Crystal.    

In the entire Profound Wind City, there were very few people who could take out 40 Essence Crystal in one go. Only the disciples of those large clans were able to do so.    

However, for those disciples of big families to take out so many Essence Crystal, which one of them wasn't a rising star? How could they be like Xu Feng? Silent and nameless!    

"Sir, do you still want to ask me about the origin of the Essence Crystal?" Xu Feng saw the shock in the old man's eyes and asked with a smile.    

The old man was stunned for a moment, then he revealed an awkward smile. "No, no, no. I will get the medicine right away. Please wait a moment, sir!"    

As soon as he finished speaking, the old man stretched out his hand to call over a waiter and passed the list of spirit medicines to him. In next to no time, the waiter withdrew all the spirit medicines that Xu Feng needed from behind.    

Xu Feng picked up the spirit medicine, and then he turned around and left.    

The old man suddenly spoke and said, "Sir, please wait. May I ask for your name?"    

Xu Feng stopped in his tracks, but did not look back. He only asked, "Why did you leave your name?"    

"Sir, you can be considered as one of the biggest customers in Celestial Mystery Tavern. If you leave your name behind, you will get a 10% discount on all spiritual herbs in the future. How about it?" The old man smiled.    

Xu Feng's heart skipped a beat. Although he still had a lot of Essence Crystal left, he would need more in the future. It would be better if he could save some now.    

Hence, he opened his mouth and said, "Xu Feng!"    

"I am Sikong Ba!!" The old man said with a smile. He repeated Xu Feng's name a few more times, and it was somewhat playful.    

Xu Feng's expression was the same as usual. He lifted his foot and walked out of Celestial Mystery Tavern. After that, he frowned. "Sikong Ba? Sikong Dong! What is the relationship between Sikong Ba and Sikong Dong?!"    

What he did not know was that after he left... The cute girl from last time, Sikong Suying, walked out from behind. With an unhappy expression, she pouted her small mouth and said, "Grandpa Sikong Ba, why did you give this kid a discount? Look at how arrogant he is. He doesn't even turn his head when he speaks. I'm not as arrogant as him! "    

Sikong Ba chuckled and said, "Just now, I felt a different aura from this kid. It's been a long time, it's so familiar... If we want to unravel the mystery this time, I'm afraid we really have to start from Xu Feng! "    

" What! " Sikong Suying's expression instantly changed slightly. "The news of great-grandfather is related to this kid?"    

"Yes!" Sikong Ba nodded his head. "The last time he came, I did not feel this aura, but this time... it was very clear!"    

Xu Feng, who was walking fast in Profound Wind City, could not calm down.    

Sikong Ba, Sikong Dong, they definitely had a connection. Who exactly was the person who died in Sikong Dong?    

Xu Feng could not help but take out that Storage Ring. He took a careful look at it before keeping it. "I must not let this ring appear in the future. Otherwise, I'm afraid that there will be trouble!"    

Although he was currently unable to think of any clues, he was vaguely able to sense it. There must be some kind of connection between the surname Si Kong and the skeleton in Purple Sun Martial Arts Secret Realm. Furthermore, there might even be a secret behind it!    

"Xu Feng? Stop!"    

Right at this moment, an unfamiliar voice suddenly sounded beside Xu Feng's ear.    

Xu Feng couldn't help but frown. He thought in his heart that he definitely didn't know the owner of this voice, but he still stopped his feet and turned around to look behind him.    

He saw two teams of patrolling City Guards walking towards him with cold expressions and fierce eyes.    

When he took a closer look, he saw that there was a huge word Lu on the chest of these City Guards. Obviously, these people were all experts of the Lu Family!    

"What's the matter?"    

Although he didn't like the tone of the other party, Xu Feng didn't want to have any conflicts with these guards of the Lu Family because of Lu Yifu.    

However, these Lu Family guards had surrounded Xu Feng in the middle. Yuan energy rolled around his body as he said, "You are wanted by the Lu Family. Surrender now and follow us to the Lu Family's prison. Otherwise... we will kill you! "
