"Did the senior agree?" Lin Ling smiled slyly, but because his facial features were sealed with strips of cloth except for his eyes, Hu Lao naturally couldn't see the change in his expression.

"What bet do you want? I'll listen, and I'll bet with you if it's appropriate." Hu Lao fell into deep thought, obviously thinking about the problem itself, which brought him a lot of trouble.

"If I'm not mistaken, you've been preparing for half a month just to be able to successfully complete that kind of work today, right? Lin Ling's words were calm, and he looked confident because of his calmness.

"Hahaha! It's a joke!" Hu Lao laughed loudly, hearty and sincere, "Hu Lao, I know talents at the age of six, apprentice at the age of eight, can build simple weapons at the age of ten, and can build immortal weapons at the age of twenty!

If any figure in the forging world heard Hu Lao's achievement, they would all applaud it.

But the kid in front of Hu Lao is a layman at all, how can he know how difficult it is.

"Wait!" Hu Lao's laughter stopped abruptly, and he said with a vigilant face, "How do you know that I have been preparing for today's work for half a month?"

"Is the senior gambling or not?" Lin Ling smiled in his eyes and did not answer.

Hu Lao smiled dumbly, his proud life obviously did not attract the attention of this child, and the arrogance in his heart also arose: "Bet! If you win, let alone let you be an apprentice, Hu Lao, I will give you another weapon to take advantage of!"

"If you lose, don't come back to me. You can't let Qi Lao speak for you!" Hu Lao glared at Lin Ling blowing his beard, and it seemed that he still respected Qi Yuan in his heart.

"A word is a certainty!" Lin Ling subconsciously straightened his waist.

Hu Lao didn't look at him anymore, turned around and walked into the room, "Come with me, I want to see what you little doll is capable of!"

Lin Ling whispered a few words in his master's ear, squeezed his eyes at him, and hurriedly followed.

Qi Yuan looked at Lin Ling's back, couldn't help but laugh dumbly, shook his head and said, "Old Hu, Old Hu, you have a lot of beard in vain, and you still have to plant it in the hands of a child." ”

Hu Lao's vestibule is the same as the house in Xiaoyao Valley, and after passing through an arch, the temperature rises sharply.

The space here was nearly five times larger than the outside, and there were all kinds of weapons hanging all over the walls, and Lin Ling had no way to recognize them all.

The forging table is also filled with a variety of forged metals, which exude different lusters. Because of the second reason of physical training, Lin Ling's perception of the aura of the outside world was no longer what it used to be, and he clearly felt that those shiny metals exuded an alluring aura.

Especially the piece of red metal placed in the very center, the scorching aura seemed to be stronger than the air, and what was even more strange was that Lin Ling always had a sense of déjà vu when he looked at that stone.

Hu Lao caught Lin Ling's gaze for the first time, and said with a smug face: "You know the Spirit Test Stone, right? The reason why the Spirit Test Stone can test a person's spiritual power affinity is because of the Spirit Eating Gu in the Spirit Test Stone, and what is in this metal is the best of the Spirit Eating Gu, the Fire Spirit Gu. In order for him to be able to blend into this flint in the heat, I wasted a lot of energy. ”

Drill flint, among the fire attribute metals, the top three metals in hardness! If you want to put this Spirit Eater Gu into it in the high temperature without destroying the activity of the Gu, it can be seen that the difficulty is high!

"Fire Eating Spirit Gu" Lin Ling's eyes showed doubt.

"You don't know? This is a university question, and when you reach the realm of the sea of clouds, you will naturally know. Hu Lao pulled the bellows, and the flames in the furnace immediately rose high, as if carnival, calling its master, "There are nine laws between heaven and earth: metal, wood and water, fire, earth, thunder, time, space, life and death, and every immortal cultivator can comprehend a law after entering the realm of the sea of clouds." If this Fire Eater Gu is forged into a weapon today, it will definitely be of great benefit to those who master the laws of fire in the future. ”

The Nine Laws of Heaven and Earth?! Lin Ling's divine sense was slightly stunned, and his eyes revealed infinite longing.

If they want to enter the sea of clouds, then the two senior brothers are already in the late stage of congenital status, and they will soon be able to reach the realm of the sea of clouds! What are the laws of heaven and earth that they have comprehended?

Hu Lao couldn't help but smile when he looked at Lin Ling's distracted appearance, took out a pitch-black three-inch dagger from a box, and said with a hint of smugness on his face: "Okay, Xiao Ling, right? But today I was lucky to be able to see Hu Lao's latest experiment!"

Hu Lao put the black and shiny dagger into the furnace and heated it evenly and meticulously.

The blade of this dagger was like lightning, and a groove had been hollowed out in the hilt, and the pitch-black chill made people feel a chill in their hearts.

After a while, sweat poured down from Hu Laoluo's beard, and the pitch-black blade was still pitch black, but Hu Lao's big face was already red.

Hu Lao's hammer is snow-white and bright, as if two snowflakes are dancing in the black swamp, and the rhythmic sound of striking iron is as melodious as spring water.

Lin Ling looked at Hu Lao's tall figure and the two snowflakes flying up and down, which were so harmonious. If the two snowflakes are graceful dancers, then Hu Lao is the conductor of the dance steps, and everything looks so beautiful.

Can striking iron be so wonderful?

However, the beautiful voice only lasted for a while, and a trace of anxiety suddenly appeared in Hu Lao's mung bean-like eyes.

The snow-white dance steps were chaotic, turning into two dragon spears that swept through thousands of troops, and the dense beating sound like rain also drove Lin Ling's heart to beat.

The pitch-black dagger was like the depth of the night sky, constantly devouring the attack of the 'Silver Spear'.

Boss Hu shouted, and the double hammer in his hand fell on the pitch-black dagger like a storm, and shouted angrily: "Not prosperous enough! Not prosperous enough!"

At the most critical moment of forging, Hu Lao discovered a fatal problem.

Although the dagger has been heated at a high temperature before, if you want to be tempered, you naturally need to heat it at a high temperature under the forging table to ensure that the temperature of the dagger will not fail due to too many changes.

The fatal problem discovered by Hu Lao was that the fire under the forging table was not strong enough, causing the temperature of the dagger to drop continuously, so Hu Lao could only hammer it at high speed to ensure that its temperature would not drop too quickly.

Lin Ling smiled, he knew that his opportunity had come, so he took the initiative to ask: "Senior, do you need my help!"

Hu Lao's hands were still beating frantically and rhythmically, and there was a hint of struggle on his face, but he immediately responded: "Help me pull the bellows!
