Ye Tian held his claws behind his back, shook a pair of vertical ears above his head, and sighed.

"This woman is not teased at all. ”

Open the map, the map is drawn with undulating mountains, and there is a small red dot in the middle of the mountains, which is where Ye Tian is going.

What place is so mysterious and mysterious? Refining medicine! Where to practice is not refining? Suddenly, Ye Tian thought again, this broken place should not be an extremely dangerous place, right?

What is this woman going to do?

Follow the map to find this place, the mountain is not high, and there is no wind, and there are no poisonous insects and beasts after careful looking.

It's a cave, and it looks like it's been around for some time.

A large clearing in front of the cave, with nothing but a few stones.

Ye Tian entered the cave, this cave was very dry, from the ground to the top of the cave was about five or six meters high, and the whole cave was about more than a hundred square meters.

There is a mirror-like stone slab on the ground at the entrance of the cave, and Ye Tian's appearance can be vaguely seen.

Sunlight shines from the entrance of the cave and reflects on the stone slab, and the sunlight scatters throughout the cave and makes the cave very bright.

In the center of the cave was a black, unknown broken pot, and next to it was a long-extinguished bonfire, and there were some unburned branches in the campfire.

Not far from the campfire was a black stick, which looked like charcoal, and was supposed to have been cut from an unknown branch, and one end showed signs of being burned by fire.

This stick should be a fire stick, I don't know what material the broken pot is, Ye Tian picked it up and looked inside, there was nothing in the pot.

Qingluan shouldn't let himself use this broken pot to refine medicine, right?

Take out the Wind Emperor Flower and throw it into the pot, use the water control technique to make a ball of water and put it in the pot, and then put the broken pot on the campfire.

He summoned another fire and threw it on the bonfire at the bottom of the pot, and the flames ignited, and Ye Tian squatted on the edge of the pot and looked at the Wind Emperor Flower in the pot.

Ye Tian was very skeptical that the flame temperature below could boil something out of the Wind Emperor Flower.

The unknown wood in the campfire was very resistant to burning, but it was still burned after two hours.

But the water in that pot didn't even smoke.

Stick your paw into the pot, and the water in the pot will be cold!

This......

It must be this broken pot!

Ye Tian poured out the water and studied the broken pot over and over again, I don't know what kind of treasure this broken pot is!

Qingluan appeared at the entrance of the cave like a ghost, and said to Ye Tiandao, who was studying the broken pot over and over again: "You don't even want to heat that pot with that fire and ordinary wood!"

Ye Tian startled Qingluan with a sudden slap, and the erection ear lying on the back of his head instantly stood upright.

"You scared me! If it doesn't heat up, what do you say?"

"There is a mountain two hundred miles south of this, and there are some iron essence wood in it, and those used for boiling medicine are the best, so you can go and cut one of them and bring it back. ”

After speaking, he threw Ye Tian a broken axe.

Ye Tian: "......"

I knew this woman wasn't going to give herself something that would be so easy to do.

Iron Wood ...... There is iron in the name, so it can't be the same as hard root iron, right?

Let's go check it out first.

Ye Tian carried the axe all the way south.

Two hundred miles away there was a black barren mountain, no, it could not be considered a barren mountain, because there were still trees on it, but only trees!

There wasn't even a single grass other than the black, iron-like leaves.

This black mountain is not very tall, it is black because it is full of iron!

The iron essence wood grows on the iron ore and uses the iron ore as nourishment.

Ye Tian stood in front of an iron essence tree and knocked down the trunk with the axe in his hand.

"Bell!"

Ye Tian: ......

The iron wood made a sound as crisp as steel.

Are you kidding me?

Are you sure this thing isn't iron?

No wonder Qingluan specially gave himself an axe, so that's it!

Picked up the axe and slashed at the iron wood.

"Bell!"

A loud sound sounded, and a huge anti-shock force came from the fine ironwood, and the axe was instantly shaken and flew out.

Looking at the trunk again, there was only a shallow trace.

I rub ......

"Phew, I don't believe it yet!"

Ye Tian picked up the axe and summoned the spiritual power of his whole body to pour into the axe.

"Bump!"

The axe had slashed into the trunk of the tree, but there was only a shallow wound.

I really used all my strength just now, but it caused such a big wound, it seems that this work is a contribution!

It's really not a bit of a laziness to steal.

Helplessly, according to his mind, he began to cut down the tree with an axe and an axe.

The consumption of spiritual power was extremely strong, and Ye Tian began a repeated meditation journey again.

After an unknown amount of time, the iron tree was finally cut down.

Ye Tian looked at the axe in his claws and said with a smile: "This thing is also a treasure! ”

As soon as he finished speaking, the axe disappeared from Ye Tian's hand, as if he was afraid that Ye Tian would steal it away.

Speechlessly glancing in the direction of the Wa Palace, Ye Tian sighed helplessly.

Bring the Iron Essence Wood into the Sumeru Mustard Seed and bring it back to the cave.

A tall piece of iron wood was thrown outside the cave.

Ye Tian took out the broken pot, there was no axe, and it was impossible to cut the broken tree again, so it was impossible to build a bonfire, and after thinking about it, he put it directly on the iron essence wood, and summoned a fire to light it.

But after burning for a long time, this iron wood was not ignited at all, and it seems that this kind of mortal fire can't help this thing.

After thinking about it, he took out the bottle of Nanming Lihuo, opened the lid and carefully poured out a trace of Nanming Lihuo.

A small ball of purple flame the size of a fingernail fell onto the trunk of the ironwood.

The trunk of the iron wood was ignited in an instant, and the flame instantly changed from the size of a fingernail to a flame-sized canvas.

The temperature of this flame was extremely high, and the broken pot was quickly burned red, and Ye Tian hurriedly summoned a ball of water and threw it into the broken pot.

"Wow!"

The water was instantly boiled dry.

Ye Tian was startled, and immediately began to summon more water, but it was useless, as long as the water entered the pot, it would be immediately boiled dry.

What to do?

Qingluan's voice appeared in Ye Tian's mind at the right time.

"How can any water resist this divine fire?"

Ye Tian sighed and said, "What kind of moth are you going to come out of?"

A gourd fell from the sky and landed at Ye Tian's feet.

"Take this gourd and go five hundred miles north of it, where there is an eternal cold pool, and you can use this gourd to pour some extremely cold water. ”

Extremely cold water......

It's another harsh environment!

But I have a rag to defend myself, and the extremely cold water must be at my fingertips.

Ye Tian tied the gourd to the fire stick, carried it to his shoulder, and walked towards the north.

The Eternal Cold Pool, this is a cold pool in the middle of a huge crack in the earth, and the extremely cold water seeps out of the crack.

There is a piece of cold ice within a hundred miles around this cold pool, and the closer you get to the cold pool, the lower the temperature.

Ye Tian came to the edge of the cold pool with the rag, looking at the extremely cold water with white smoke and the same color as after pouring lime, he used the black fire stick to pick the gourd and put it into the cold pool.

"Gollum, Gollum, Gollum......"

The water of the cold pool bubbled into the gourd.

But suddenly, the gourd suddenly had a strong suction, and the water of the cold pool was sucked into the gourd like a river pouring in.

Suddenly, Ye Tian had a very bad feeling, there shouldn't be anything in this cold pool that was alarmed, right?

He never believed that he could get the Extremely Cold Water so easily this time.
