An old man and a young man looked at each other and smiled, and they both saw the determination to break the kettle in each other's eyes.

"Okay! let's start!" Wu Shuang rolled up his sleeves, held the giant hammer with one hand, and smashed it towards the sword embryo in the flames.

When there was a loud bang, the dust on the stone wall above his head fell, but the sword embryo did not change at all.

Wu Shuanghun didn't care, and shouted at Shen Zhuoyu: "Come on, help me control the bellows." ”

"Okay!" Shen Zhuoyu was full of energy, and he also rolled up his sleeves, but when he saw the instrument in front of him, he was a little at a loss.

Wu Shuang knocked a few times, and found that he was still standing stupidly, only then did he suddenly remember that he hadn't taught him how to use it.

He put down the hammer at the moment, grasped the mechanism with both hands, and said, "This thing is very tough, and it takes a lot of effort to use it! As he spoke, he took a horse step, his feet stood on the ground like iron pillars, his knees bent slightly, and then he shouted: "Look at it!" The center of gravity suddenly shifted, his knees straightened instantly, his waist rotated, and he drove his arms to pull the bellows.

The huge bellows began to operate at an alarming speed, and the flames in the furnace suddenly rose a foot high, and even the blue light on the sword embryo of the Excalibur was covered.

"Borrowing the strength of your knees and waist can you spend the least amount of effort to make the bellows turn faster!" Wu Shuang quickly picked up the hammer and knocked it several times while the fire was hot.

Shen Zhuoyu was amazed, he never thought that there were so many ways to pull the bellows.

However, just when he thought that this meeting would be very effective, he saw that the sword embryo still did not change much, but a strange aura shot out of it. The breath was cold and uncomfortable.

"It's no wonder that if it had been so easy, it would have been done in so many years. Wu Shuang guessed Shen Zhuoyu's thoughts, and said with a smile: "Pull the bellows quickly, if the two of us cooperate tacitly, we will definitely be able to get twice the result with half the effort, maybe we can really catch up with the ten-day period!"

Shen Zhuoyu snorted, didn't think about it anymore, learned the movements of Fang Cai Wu Shuang, and began to blow the bellows.

This bellows is also made of special materials, and it is difficult to pull without the force of a thousand catties. Shen Zhuoyu was still a little struggling at first, but fortunately, his body was far beyond ordinary people, and he gradually got used to it after pulling a few times, and he did it well.

Wu Shuang glanced at him, the surprise in his eyes couldn't be hidden, and he said secretly: "This son must have an adventure that is difficult to find in a hundred years, otherwise, according to his martial arts internal strength, how can it be so easy?"

He got a powerful assistant, and he no longer had to worry about the fire, and he could finally concentrate on forging the divine sword, and the progress was twice as fast as before.

When the loud noise continued to echo in the ground, thirsty and hungry, their own two girls sent water and food, tired and sleepy, so they meditated on the spot and rested, and waited until they had enough rest to continue to forge swords.

Shen Zhuoyu could easily pull the bellows at first, but after a long time, he also felt soreness all over his body. But he has always been tenacious, how could he delay the progress of forging the sword because of his own affairs, and when he pulled, he used the Five Elements True Qi to reduce the burden on his body.

When it is time to meditate and rest, seize the time to breathe and recover the consumed true qi. In this way, it is really a matter of forging a sword and practicing at the same time. In just a few days, the True Qi was exhausted, recovered, depleted, and restored again...... After such a high-intensity cultivation, his internal strength was growing at an astonishing rate.

Wu Shuang saw it in his eyes, with a smile on the corner of his mouth, but he didn't say anything, but secretly praised in his heart: "This son's innate conditions are too good, if he is someone else, let alone use this to cultivate internal strength, I'm afraid he won't be able to last three days, and he will be exhausted to death." ”

There is a hidden passage in the stone chamber that leads to the outside of the mountain, and the huge stove also has a special chimney, so that the two of them stay in it all night, although they also feel suffocated, but they will not suffocate to death because the air is exhausted.

It's just that I'm underground, and I don't know the years outside after all. Fortunately, the second girl will deliver food once in the morning and once in the evening, and the two will infer the rest of the food according to the number of times the second girl delivers food.

Wu Shuang suddenly slowed down the progress of forging the sword, and every time he hammered, he was particularly careful.

Shen Zhuoyu didn't understand the reason, so he asked: "Senior, counting just now, it is the fourteenth time that Erniu has come to deliver food, so it has been seven days." The seniors should have stepped up and stepped up to complete the Excalibur, why did they slow down at this juncture?"

Wu Shuang didn't answer when he heard this, his expression was extremely serious, and his thick eyebrows were tightly wrinkled.

Shen Zhuoyu was inconvenient to ask, so he had to continue to pull the bellows hard, but his heart was changing: Could it be that the seniors knew that it was too late and had the idea of giving up?

Wu Shuang knocked more and more slowly, as if he was not forging a sword, but carving. Every time you gently hit a hammer, you have to pick up the sword embryo and observe it carefully.

It's just that the more he arrived, his brow furrowed more and more.

Shen Zhuoyu faintly felt that something was wrong, and was about to ask carefully, but saw Wu Shuang stumble suddenly, his face turned pale in an instant, and Teng Teng took a few steps back before he stood firm.

"What's wrong with you, senior!?" Shen Zhuoyu hurriedly stepped forward to help, his chest was pounding, he saw Wu Shuang like this, and knew that something big must have happened.

Wu Shuang closed his eyes in pain, suddenly broke away from Shen Zhuoyu, and fell to his knees.

"Senior ......" Shen Zhuoyu could only stand aside, completely unaware of what was going on.

Wu Shuang raised his head to the sky, his eyes were full of grief, and he groaned in a trembling voice: "Chu Yushan, I can't stand you...... I'm sorry for you!" He said two words, and couldn't help but howl.

The cry was so grief-stricken that anyone who listened to it would be moved. The second girl on the ground heard the cry, and rushed down, seeing Wu Shuang like this, she who had always been noisy also quieted down and squatted beside him silently.

Shen Zhuoyu let out a long sigh, and at this time, he didn't need to ask to know that he must have failed to forge the sword.

But he really wanted to know, why did it fail? Glancing at the sword embryo in the furnace, it had already taken shape, and he believed that if it continued, it would be completed within the time limit.

But now Wu Shuang is so sad, even if he doesn't want to believe it, he has to believe it.

Could it be that God turned a blind eye to the hard work that he and Wu Shuang even said?

Thinking of this, he was even more sad for Wu Shuang, you must know that Wu Shuang has been casting this sword for thirty years, and now it has been in vain, this kind of pain is no less than that of a white-haired person sending a black-haired person.

He took a step forward, walked to Wu Shuang's side, knelt down slowly, arched his hand to the sky, and said angrily: "Senior Chu, although the juniors are soft-spoken, they also hope that the seniors must believe what I say below......

Wu Shuang's crying stopped abruptly, he turned his head and looked at the young man beside him in surprise.

Shen Zhuoyu made a decision, and said loudly: "Although you died young, you are happier than many living people, at least the people here have never forgotten you, silently miss you until now, in the eyes of the younger generation, such a life, there is really no regret!

When Shen Zhuoyu spoke, he didn't notice that Wu Shuang's tears were no longer flowing, and a strange smile even appeared on the corner of his mouth.
