One thing is a stick about 20 centimeters long, and the other thing is something like a stand 10 centimeters high.

Seeing these two things, Su Nantian's expression suddenly froze.

Although he didn't know what these two things were or what their uses were, he could see the materials they were made of.

That is actually Thousand Years Cold Iron which is a hundred times more precious than Hundred Years Cold Iron!

Warrior weapons made of cold iron can be called magical weapons. The older they are, the stronger and sharper the weapons are.

Weapons forged from a century-old cold iron can withstand any attack below the mid-level master level, while weapons forged from a thousand-year-old cold iron can withstand any attack below the mid-level innate level.

It was precisely because of the preciousness of Millennium Cold Iron that Su Nantian was shocked.

Wang Guiyu is just an ordinary member of the bottom team of the Martial League, but he can actually take out such a precious thing!

A glint flashed in Su Nantian's eyes.

It seems that Wang Guiyu’s identity is not simple!

After Wang Guiyu took out two things, he started to operate them.

Not long after, the thing similar to a bracket was assembled by him into a one-meter-high tripod, and the stick continued to expand and contract in his hands, extending to more than ten meters in length.

He placed the stick on the tripod, one end just inserted into the bottom of the stone door, and the other end was raised high.

Then, Wang Guiyu pointed at the raised end and said calmly: "Nantian, let's try again now!"

Su Nantian looked suspicious, is this really okay?

Although he was doubtful, he still walked to the cocked end of the stick, then held the head of the stick, and with all his inner strength, he pressed it slowly.

"Boom!"

Under Su Nantian's leveraging, the stone door actually moved and slowly rose up.

Seeing this, Su Nantian looked happy and increased his strength.

Finally, the stone door was completely opened.

"Wang Guiyu, that's okay!"

Seeing this, Su Nantian couldn't help but look at Wang Guiyu in surprise.

He never expected that Wang Guiyu's physics knowledge could be used in this way.

"Combining martial arts with physics is my lifelong pursuit, Wang Guiyu!"

Wang Guiyu was unfazed and said calmly.

"Okay, let's go in then!"

Su Nantian smiled slightly and stepped into the space inside the stone gate with Wang Guiyu.

Inside the stone gate is a very large space.

Surrounding the space are lamp posts that are lit with fire.

In the center of the space is a stone platform, and on top of the stone platform is a stone chamber measuring dozens of square meters.

In front of the stone chamber, there is a huge alchemy furnace, with blazing flames burning under the alchemy furnace, and heat is constantly rising from the alchemy furnace.

In front of the alchemy furnace, there are many wooden boxes containing heavenly materials and earthly treasures, half of which are empty.

Seeing this scene, Su Nantian couldn't help but be speechless.

He could tell that someone was "refining elixirs", but the elixir refining technique was a bit too weird. He was prepared to say that the other party did not know the elixir refining technique at all, and would directly boil these precious heavenly materials and earthly treasures as Chinese medicine.

Got it!

It’s simply a waste of natural resources!

"Who disturbed my Qingxiu?"

At this moment, a loud shout suddenly came from the stone chamber.

Immediately afterwards, a figure was seen walking out of the stone room.

It was an old man, with his hands behind his back and a chilling light shining from his eyes, staring at Su Nantian and the two of them.

Seeing the old man, Su Nantian's hair stood up immediately.

Because the other party gave him an unfathomable feeling, making him feel that his life was threatened.

At least the eighth level of the master's peak!

How could there be such a strong person here?

Sure enough, this task is not as simple as imagined!

"run!"

The next moment, Su Nantian directly pulled Wang Guiyu and ran towards the stone door.

"snort!"

Seeing this, the old man snorted coldly and said: "You disturbed my Black Mountain ancestor Qingxiu, and you still want to run away?"

As soon as he finished speaking, he took action directly and grabbed Su Nantian and the two of them through the air with one claw.

A huge palm made of energy appeared behind Su Nantian and the two of them.

Seeing that he could not dodge, Su Nantian pushed Wang Guiyu forward with his hand, then turned around and punched the powerful palm.

"boom!"

Su Nantian was defeated, and his body suddenly flew out, finally hitting the mountain wall and falling to the ground.

He spat out several mouthfuls of blood and was seriously injured.

"oh?"

Seeing that Su Nantian was not killed with one palm, the Black Mountain ancestor was a little surprised.

Then, he slapped Su Nantian with another palm.

This palm was a bit more powerful than before.

Feeling this palm, Su Nantian looked solemn.

He was considering whether to use the One Finger of Heaven and Earth.

If this finger fails to kill the opponent, then he will fall into a certain death situation.

"Look at me!"

At this moment, a voice came out.

Wang Guiyu suddenly rushed over and took out something from his pocket. It turned out to be a pistol made of thousand-year-old black iron.

"Just in time for you to try the weapon I just developed!"

Wang Guiyu showed excitement and directly pulled the trigger.

"Bang!"

A bullet shot towards the Heishan Ancestor at an unimaginable speed, and actually pierced the Heishan Ancestor's palm.

"ah!"

The Black Mountain Ancestor screamed, covering his hands and moving backwards, finally regaining his balance.

Seeing this scene, Su Nantian was shocked.

What the hell is the gun in Wang Guiyu's hand?

It is so powerful that it can even injure such strong men!

"Hahaha! This is the perfect combination of physics and martial arts. This is art!"

Wang Guiyu's face was filled with a strong sense of accomplishment.

"Zizzizi..."

There was a look of pain on the face of the Black Mountain Ancestor. The blood hole in his palm seemed to want to heal, but there was a force blocking its healing, and white smoke kept coming out.

He held back the severe pain and looked at Wang Guiyu angrily: "Boy, you angered me! I will make you pay the price!"

The next moment, his body shot towards Wang Guiyu.

"Bang bang bang..."

Wang Guiyu didn't seem to be afraid, he was extremely calm and kept pulling the trigger in his hand.

"ah……"

The Black Mountain Ancestor used his body movement technique, and although he dodged many bullets, he was still hit by one.

However, he finally came to Wang Guiyu and strangled Wang Guiyu's neck: "Boy, you dare to hurt me, I will torture you!"

"Whoosh!"

At this time, Su Nantian suddenly rushed towards the Black Mountain Ancestor.

He wants to save Wang Guiyu!

"Su Nantian, leave quickly!"
Chapter completed!
