The so-called hard work pays off, after a few months of rummaging, Lin San finally found a way to fuse the yin and yang attributes in an inconspicuous classic, Lin San tried it and found that the effect was not bad.

In this way, Lin San arranged a formation in the room, and then began to fuse the Xuan Bing Cold Iron into the Demon Suppression Knife.

This is a very laborious thing, Lin San first had to melt the Xuanbing cold iron into molten iron with the fire, and then carefully fused the molten iron into the Demon Knife, there must not be a trace of error in the whole process, otherwise the Demon Knife would be seriously damaged, it can be said that Lin San took a great risk by doing this.

Day after day.

It took a full month for Lin San to fuse all the Xuanbing Cold Iron into the Demon Suppression Sword Array.

After fusing the Xuan Ice Cold Iron, the Demon Suppression Knife was even more powerful, and the hardness of the blade reached an unbelievable level!

Lin San looked at the hundreds of Demon Suppression Swords that kept spinning in front of him, and his face was full of satisfied smiles.

......

Deep mountains and old forests.

Niu Shenguang sat on a stone, his eyes stared into the distance, he was dazed, he hadn't seen him for a few years, Niu Shenguang's complexion was very haggard, and his hair was a lot whiter.

"Alas......" Niu Shenguang sighed softly and said to himself: "Heavenly madness, where are you?

"Stepping on the ......" There was a sound of footsteps behind him.

"Heavenly madness!" Niu Shenguang turned around suddenly, and when he saw the appearance of the person who came, a trace of disappointment flashed on Niu Shenguang's face, it was not Niu Tianguang!

The person who came was a slender young man, dressed in a gray robe, holding a fan in his hand and a gauze scarf on his head.

"Who are you?" asked Niu Shenguang, staring at the scholar vigilantly.

The scholar bowed his hand: "Dare to ask if you are a senior of Niu Shenguang?"

Niu Shenguang nodded: "Yes, I'm Niu Shenguang!"

"It's called Sun Baibai, it's ...... Niu Tianmad's subordinates. The scholar introduced himself.

"What?, are you a subordinate of the Heavenly Madness?!" Niu Shenguang's eyes suddenly opened: "What you said is true?"

Sun Baiyu took out a jade plaque from his arms: "Senior Niu, please take a look!"

Niu Shenguang stretched out his hand and sucked it, and the jade pendant automatically flew into his hand, Niu Shenguang used his divine sense to probe the jade plate, and a smile appeared on his face: "It's really crazy...... I didn't expect that the Heavenly Maniac had advanced to the stage of transforming into a god...... Okay, yes......"

Sun Baiduo smiled and said: "My master misses you very much, let me come to visit you!"

Niu Shenguang frowned: "Why didn't he come to see me?"

"This ......" Sun Baiduo hesitated: "My master is busy with affairs, and I really can't spare time to come and see you......"

"Why are you so busy? I haven't come to see his father for several years?!" Niu Shenguang's tone was a little dissatisfied.

"I don't dare to comment too much on the host's affairs...... Senior Niu, don't worry, it won't be long before the master will come back to see you!" Sun Baiduo said.

"Alas......" Niu Shenguang sighed: "I hope." ”

"Uh...... That ......" Sun Baiduo hesitated for a moment and said: "Senior Niu, the master asked me to come this time, and there is one more thing ......"

Niu Shenguang looked up at Sun Baibai: "What's the matter?"

"That's right, the host asked me to borrow something from you. Sun Baiduo said as he observed Niu Shenguang's expression.

Niu Shenguang frowned: "What is it?"

"Zijin Dan. Sun Baiduo said slowly.

"What does Tianmad want Zijin Pill to do?" Niu Shenguang's expression was a little stunned, and then he thought of something: "Is Tianmad seriously injured!" Zijin Dan is an heirloom of the Niu family, which is used to heal injuries, no matter how serious the injury is, as long as you take Zijin Pill, the injury will heal quickly, which is very magical.

Sun Baiduo waved his hand again and again: "No, my master is not injured." Before coming, Niu Tianmad specially told Sun Baiduo that he must not disclose his injury, so as not to worry Niu Shenguang.

"Since Tianmad is not injured, what does he want Zijin Pill to do?" asked Niu Shenguang suspiciously.

"This ......" Sun Baibai said with some embarrassment: "I don't know very well, I was just ordered to come and borrow the Zijin Pill...... That, my master said, if the cow seniors refuse to borrow it, then forget it!"

"Who said I wouldn't borrow!No, Tianmad is my son, and it doesn't hurt if I give him the Zijin Pill directly!" Niu Shenguang snorted.

Sun Baiduo's eyes lit up: "More seniors......

Niu Shenguang waved his sleeves, and a purple pill appeared in front of him.

Although Sun Baiduo was far away, he could also feel the surging medicinal power emanating from the Zijin Pill, Sun Baibai nodded secretly, and said in his heart: This Zijin Pill is indeed a holy medicine for healing!

"Before giving you the Zijin Pill, I have a question. Niu Shenguang was not in a hurry to hand over the Zijin Pill.

"Senior Niu, please ask, I must know everything!" Sun Baiduo hurriedly said.

Niu Shenguang looked directly at Sun Baibai, and said slowly: "Where is the Heavenly Mania now?"

"Ah......" Sun Baibai was stunned, he didn't expect Niu Shenguang to ask this question: "Senior Niu, to be honest, I don't know where the master is." Seeing that Niu Shenguang didn't believe it, Sun Baiduo explained: "Every time, the master contacted me, and I couldn't find the master at all." ”

Niu Shenguang seems to believe it a little, his son himself knows best, Niu Tian is crazy and careful, and he really does this kind of thing.

"Senior Niu, if there are no other problems, I will leave......" Sun Baiduo said cautiously.

Niu Shenguang glanced at Sun Baibai: "If I want to find you, how can I contact you?"

"Well...... this" Sun Baibai hesitated for a moment, and then took out a token from his arms: "This is a communication token, there is a trace of my divine thought on it, if the senior Niu wants to find me, just use this token to send a message, after I receive it, I will rush over as soon as possible." ”

Niu Shenguang took the token and inspected it, then put it away directly, and then handed the Zijin Pill to Sun Baiduo: "This pill is very precious, you have to keep it well!"

"Yes, I know, Senior Niu, if there's nothing else, I'll leave first!" Sun Baibai said hello and turned to leave.

Niu Shenguang's figure flashed, and he quietly followed, and when he came to the edge of the woods, Niu Shenguang stopped his figure, and his face showed a trace of surprise: "I can't even find the trace of that Sun Baibai, how is this possible...... That Sun Baibai was just an ordinary Yuan Infant Monk, how could he have disappeared right under my nose? Could it be ...... What kind of treasure did that Sun Baibai carry on his body that could hide his traces? Well, it must be like this! Alas, I blame myself for being too careless and letting that Sun Baibai slip away!" Originally, Niu Shenguang wanted to secretly follow Sun Baibai to find his son, but who knew that in the end he would lose people, Niu Shenguang sighed: "God crazy, when will you come back, I really miss you for my father!"
