With a punch that killed the Iron Rock Turtle, Zhu Jiu recovered from that crazy state.

"I ...... Did I break through? ”

Zhu Jiu looked at his flesh and blood fist, feeling the majestic power contained in it, and his heart was shocked beyond measure.

He thought about it for a long time, and the second-order realm that he had been so desperate for had broken through in such a way!

Thinking of this, Zhu Jiu hurriedly looked at the system panel.

[Host: Zhu Jiu (minor injury)]

[Title: Martial Arts Master (You have entered the realm of near-Dao skills, and you have created your own second-order ancient martial arts, which can be called a martial arts master)]

[Ancient Martial Arts: The first layer of the Burning Sun Golden Body Gong (the Burning Sun Golden Body Gong is a second-order ancient martial art created by the host, and it takes 1000 points to upgrade to the second layer, as well as 100 kilograms of first-order metal), and the Heart Ape Gong is level 9 (the Heart Ape Gong is a first-order heart refining method, and it cannot be upgraded before advancement)]

[Credits: 2386 (The system can absorb dark energy and convert it into integrals)]

[Warning: Dark energy has exploded, the second wave of catastrophe has arrived, please prepare the host to deal with the catastrophe]

"Sure enough!" Zhu Jiu said excitedly: "I have really entered the second order, and the title has changed from an entry-level martial arts master to a martial arts master!" ”

"When I was in the first order, I barely had second-order combat power, and now my combat power is definitely beyond the ordinary second-order!"

Feeling the surge in his strength, Zhu Jiu's heart was full of pride.

Not only because of the growth in strength, but also because of the affirmation of the system, he won the title of martial arts master.

"By the way, I haven't seen what is so strong about this Burning Sun Golden Body Skill."

Thinking of this, Zhu Jiu entered the system and checked the effect of this ancient martial art.

【Ancient Martial Arts: Burning Sun Golden Body Skill (Second Order)】

[Introduction: An ancient martial art created by the martial arts master "Zhu Jiu", integrating boxing, external strength, internal strength and knife skills, breaking through the shackles of external and internal strength, using the viscera as the furnace and turning metal into nourishment, the body is as indestructible as pure gold from the inside out]

"Take the viscera as the furnace and turn the metal into nourishment? Make your body as indestructible as pure gold? Zhu Jiu secretly said in surprise: "What a strong Gu Wu, this is what Gu Wu should look like!" ”

"Fist the mountains and rivers, step on the sun and the moon, this is what Gu Wu should look like!"

"Although I haven't reached this realm yet, as long as I keep cultivating, I will be able to do this sooner or later!"

Zhu Jiu clenched his fists, his heart was full of motivation, and then he looked at the iron-eating rock turtle under his feet.

At this time, the iron-eating rock turtle was already motionless, and it was whimpering.

"By the way, doesn't this guy use metal ore for food?" Zhu Jiu suddenly realized: "Then isn't there metal ore where it lives?" ”

Thinking of this, Zhu Jiu's eyes lit up: "In this way, the resources for my cultivation of the second layer of the Burning Sun Golden Body Skill have fallen!" ”

With that, Zhu Jiu couldn't wait to rush to the cave.

At this time, this iron-eating rock turtle has been killed by him, and there must be no threat in the cave, so you can enter it with confidence.

The cave was dark and smelly, Zhu Jiu turned on the special flashlight that Zuo Yiyi gave him and looked into the cave.

"It's pretty deep."

There were a lot of feces and beast bones on the road, so Zhu Jiu carefully avoided them and walked inside.

After walking for about a few tens of meters, the temperature inside the cave became lower and lower, as if walking into an ice cellar.

Finally, when Zhu Jiu turned a corner, his vision suddenly opened up, and he saw that there was a very spacious cave in front of him, and there was even a small lake of about dozens of square meters.

The lake is very small, but it is very deep, and Zhu Jiu used a flashlight to shine into it and found that he couldn't see the bottom.

"Is it so deep, leading to an underground river?" Zhu Jiu muttered to himself, thought about it, and decided not to go down first.

He is generally watery, and if there is any danger below, it is easy to have problems.

There's no need to take that risk.

"Isn't there anything else but this lake?" Zhu Jiu frowned, looked around, and found that there was nothing on the ground except bones and feces.

"That's not right."

Zhu Jiu suddenly saw a sand pit on the ground, covered with bones, and there was no silver three hundred taels here.

"If I'm not mistaken, this is probably the place to hide things, right?"

Zhu Jiu smiled and brushed aside the bones and gently stirred with the sand.

"Huh?"

At the beginning, it turned out to be not the treasure he imagined, but a very smooth, slender thing.

"What is this?" Zhu Jiu took a few turns to remove the sand and found that it was a dark yellow egg inside.

"Turtle eggs?" Zhu Jiu blinked his eyes, it was the first time he had seen a turtle egg, and it was so big.

The egg in front of me is almost the size of a basketball!

"This thing...... Big supplement, right? Zhu Jiu smiled and picked up the turtle egg, and found that the eggshell was very hard, like an iron sheet, so there was no need to worry about breaking it.

"A second-order evolution beast, plus a turtle egg, can be regarded as a big gain."

Zhu Jiu muttered, and Mei Zizi walked outside the cave.

At this moment, he flickered his flashlight and suddenly realized that something was wrong in the innermost part of the cave.

"Why is the color of the mountains here a little different from other places?" Zhu Jiu approached suspiciously, and wiped the rock with his hand.

When he was studying, he had studied civil engineering, and he knew very well that the rocks in a section of the mountain should not change much.

The face of the palm in front of him is obviously a dark cyan weakly weathered tuff, but there is a black-brown fault in the middle, and the contrast is very clear when you look closely.

(Note: The face of the palm refers to the rock in front of him)

"What is this, there won't be radiation, right?" Zhu Jiu didn't touch this black-brown fault with his hands, but cut a piece with the Xuantie Sword.

With a sword down, Zhu Jiu found that the black-brown rock was actually very hard, harder than granite, and it revealed a cold aura.

Zhu Jiu looked fixedly, and a system panel suddenly appeared in front of him.

"It's no ordinary rock." Zhu Jiu couldn't help but laugh.

"If you can trigger the system panel, it must be a baby." As he spoke, he looked towards the system panel.

[Item: Cold Iron Ore]

[Grade: Second Order]

[Introduction: The second-order iron ore that exists near Hantan has average toughness, but excellent hardness, and is suitable for building weapons]

"The raw ore of second-order iron ore!!" Zhu Jiu was instantly overjoyed, and grabbed the ore on the ground.

"It's really hard." Zhu Jiu pinched it and pinched a pit on it.

With his strength, he was able to pinch out a pit, and the hardness of this raw ore is comparable to that of dark iron, so you can imagine how hard it will be after refining it into a weapon.

He's short of weapons right now, and this cold iron ore is just in time!

And it's not a piece of ore, it's a vein!

"I don't know how big this vein is, if it's big enough, it's really rich."

A second-order ore vein, Zhu Jiu knew on his toes that it must be very precious.
