Ling Feng and the three of them stepped on their swords and went directly to the Guanhai Tower of the Dan Palace, at this time, Shangguan Wanqing seemed to have already received the news and was waiting for them.

When Ling Feng and the three of them appeared in Shangguan Wanqing's divine sense, she frowned slightly.

"Grandma, Ling Feng is back, this time I have gained a lot from refining Chixiao, and I have come to thank my aunt and grandmother. Ling Feng said excitedly.

This time, Ling Feng not only re-refined an intermediate spiritual weapon, but also refined all the way to the heart, originally there was no barrier to his eighth layer of qi refining, at this time his cultivation had been completed, just waiting for the right opportunity, he would be able to break through the eighth layer and reach the ninth layer of qi refining.

Once Ling Feng's cultivation reached the ninth level of Qi refining, he could explore the mystery of foundation building.

"Even if you kid has a little conscience, but being able to return from there unharmed also shows that you have a job. Shangguan Wanqing said with a slight relief.

Ling Feng's rapid growth surprised Shangguan Wanqing, and made her even more gratified, in her heart, she always stubbornly regarded Ling Feng as the shadow of the person in her heart.

"It's about to break through the eighth layer of qi refining, and ordinary inner disciples will forcibly suppress their cultivation, and they won't build a foundation until the thirteenth layer of qi refining, so that the foundation of their avenue will be stable, and they will have a greater grasp of the knot in the future. However, my advice to you is: After refining the ninth layer of qi, start building the foundation until you succeed. Shangguan Wanqing looked at Ling Feng, who was handsome and dusty, and said worriedly.

Ling Feng nodded slightly, knowing in his heart that Shangguan Wanqing's words were not finished, and as a potential half-demon, it was recorded in countless classics: "It is impossible to build a foundation." "Those inner disciples who forcibly suppress their cultivation, once they reach the last step, they will definitely come to fruition, and there is a high probability that they will succeed in building the foundation, but he can't.

Ling Feng restrained some of his emotions, and a Thunder Sword Stone Embryo surrounded by a trace of electric light appeared in his hand, and slowly handed it to Shangguan Wanqing.

When Ling Feng took out the Thunder Sword Stone Embryo, Shangguan Wanqing immediately discovered that this was a thunder attribute item, but with her years of experience in alchemy, she couldn't judge the grade of this item.

And Chu Mo and the ancestor of the Chu family on the side were also at a loss, and obviously didn't recognize what the item was.

Ling Feng told everyone how he photographed this stone embryo.

The three people next to him had different expressions on their faces. Shangguan Wanqing admired Ling Feng's gaze, she also thought that this thing was not an ordinary product, while the Chu family brothers were a little heartbroken, spending hundreds of thousands of spirit stones, just buying a strange thing of unknown grade, it was too unwise.

Ling Feng glanced at the two brothers, seeing a painful expression on their faces, he didn't understand what the two of them were thinking, but Ling Feng could only shake his head slightly, it was impossible for him to tell the two that he decided to take this thing because of the abnormality of the formation diagram.

The two brothers of Shangguan Wanqing and the Chu family, each holding the stone embryo in their hands, looked at it for a while, and finally frowned slightly and shook their heads gently.

"Childe, this stone embryo is likely to be a strange thing, or a material we haven't seen before, but the possibility that it is a ground-level material is very small, otherwise it would not be easily photographed by Childe. The ancestor of the Chu family said with a look of regret, he did not regret this stone embryo, but the hundreds of thousands of spirit stones.

Ling Feng smiled slightly

, it doesn't matter in my heart, anyway, this spirit stone was sent to the door by a guy named Shi Qing.

"Ling Feng, I don't recognize what this thing is, but I always think it's extraordinary. Shangguan Wanqing hesitated a little, she had been cultivating immortals for more than seventy years, and there were very few materials that she had not seen.

Ling Feng calmly took the stone embryo from the Chu family ancestor's hand, a trace of spiritual power came out through his fingertips, and a drop of blood slowly flowed out, which happened to drop onto the stone embryo, and a burst of lightning made a burst of lightning, and a thunderous sound sounded throughout the Guanhai Tower.

Shangguan Wanqing's eyes widened slightly, and a jade hand covered her small mouth, unable to calm down for a long time.

The sound of thunder did not last long, and after a while, the thunder sword stone embryo hovered in the air, giving people a powerful coercion.

"This turned out to be a natural spiritual weapon, and it only needs to drop blood to recognize the master?" The ancestor of the Chu family was dumbfounded, his two eyes were about to fall to the ground, and he couldn't help but say.

"Ahem......"

Ling Feng's right hand clenched into a fist slightly, against his lips, and coughed lightly.

When Shangguan Wanqing and the Chu family brothers heard the sound, they gradually came to their senses and restrained their minds a little.

"Ling Feng, this is really a great opportunity, this is a treasure set by the Heavenly Dao, and its future is immeasurable in the future, but this is also a disaster thing, you have to be extremely careful. Shangguan Wanqing was once again refreshed her perception of Ling Feng by the Thunder Sword Stone Embryo, but she still said worriedly.

"Auntie, don't worry, I won't use this Thunder Sword Stone Embryo easily, besides, I seem to be able to feel that its spirituality is somewhat lacking, and the people who got it at the beginning were too anxious to wait for it to completely transform. Ling Feng recalled the stone embryo with a thought and said slowly.

Shangguan Wanqing smiled, her beautiful eyes were longing, the Chu family brothers on the side caught a glimpse of this scene, their minds were already in a daze, and in their hearts, they deeply suspected that the news circulated by the sect was very likely to be true.

"A natural spiritual artifact, there are not hundreds of thousands of years, where the transformation can be easily completed, how can ordinary people afford to wait, even if others can, then do you dare to guarantee that this stone embryo is still yours?" Shangguan Wanqing scolded with a smile.

When Ling Feng heard this, his face flushed slightly, and he touched his nose with some embarrassment, deeply agreeing in his heart.

"However, I heard that the Chen family has a strange object, called: 'Thunder Binding Stone', I heard that their family was preparing to refine a thunder attribute spirit weapon back then, and it cost a huge price to get it, but unfortunately the thunder attribute materials are rare, and there are always a few things that have not been found, and finally they have stopped thinking about it. Shangguan Wanqing said meaningfully.

Ling Feng smiled slightly, he didn't seem to hear Shangguan Wanqing's words just now, but in the bottom of his heart, he had secretly remembered the name "Thunder Binding Stone".

Ling Feng and Shangguan Wanqing glanced at each other as if they had a tacit understanding, and they both understood what the other party meant.

Not long after, Ling Feng took the two brothers of the Chu family out of the Dan Palace, until they reached the red dust stone tablet, and each of them shot away in different directions with the light of escape.

The Chu brothers naturally wanted to return to the courtyard of the bazaar, and they also had to send the token handed over to them by Gongzi to Jing Peng, so that he could come to the Dan Hall and follow the elders to learn alchemy.

In the hearts of the two of them, they had some disagreement with Ling Feng's practice of spending so much effort to promote the old man, thinking that it had consumed too much of Ling Meng's resources

, but they didn't realize that they were more integrated into the Ling League, and everything was considered by the Ling League.

Ling Feng returned to the courtyard of the inner gate alone, went directly into his room, and sat cross-legged on the futon.

Originally, Yu Qingrong wanted to ask Ling Feng when she was going to receive the Inner Gate Promotion Task, but she only saw the closed door of the room, her face was slightly annoyed, she hesitated for a moment, and then returned to her room in a daze.

Ling Feng put all the five flying swords into the jade jue, and also put the fire attribute flying sword of the intermediate magic weapon from before. Suddenly, the red light in the jade jue space was great, and Chixiao, who was an intermediate spirit weapon, swallowed the fire attribute flying sword in one gulp, leaving only some scattered materials.

A hand slapped on his thigh, Ling Feng stood up excitedly, and sure enough, as he expected, as long as there were enough treasures of the same attribute, his sword formation would be able to transform continuously.

From beginning to end, the five-pole sword array was Ling Feng's biggest hole card, his jade jue was now hanging high in the air of the array, turning into a bright moon, and the five flying swords turned into five starlight, nestled around the jade jue.

The gradual completion of the sword formation gave Ling Feng a strange feeling, as if there were some more things in the entire formation space, something he didn't understand yet.

Ling Feng's divine sense slowly extended to Mo Shan's room, and Mo Shan, who was meditating, suddenly opened his eyes and hurriedly left the room.

"Childe, Moshan has arrived. Mo Shan said respectfully, he didn't expect that Gongzi could already transmit his thoughts through his divine sense. As a true foundation-building monk, it is difficult for him to do it, unless there is a contractual relationship.

"Come in and talk. Ling Feng in the room replied lightly.

Moshan pushed open the door, and as soon as he came in, he found that Gongzi was in a trance, obviously having something on his mind.

"Early tomorrow morning, you will personally go down the mountain and hand over these two letters to Xin Yun. Ling Feng didn't say too much and said bluntly.

Mo Shan took the two letters handed over by Ling Feng, did not dare to slack off, and carefully put them away. But he didn't leave directly, but stopped talking a little.

Ling Feng frowned slightly, and scolded a little angrily:

"If you have something to say, you should rest early. ”

"Childe, the masters of the inner courtyard are like clouds, once I leave, if there are any more masters to provoke ......" Mo Shan was very worried about the safety of his son in the inner courtyard.

"Hmph, you, a foundation building elder, stay in my courtyard every day, when will my newly refined sword formation be unveiled?" Ling Feng said with a hint of amusement in his eyes, of course he was not targeting Mo Shan, but those who were preparing for the next life.

Ling Feng's words did not reassure Mo Shan, in his heart, Gongzi was strong, but whether it was Gao Kun, Xuan Shiliu, or Wu Yan, they were essentially low-level cultivators of the seventh or eighth layer of qi refining, and in the inner courtyard, there was the existence of monsters like the thirteenth layer of qi refining, these people could build a foundation at any time, and even he might not have beaten them.

"Don't worry, it's not very far from the Dan Palace, I can't beat it, won't I run?" Ling Feng smiled slightly.

Mo Shan was stunned when he heard this, an upright man like him never thought of running away when he encountered a battle.
