at the frozen fruit and my undead will upgrade to a mythical beast

A valley covered in red soil.

The air seemed to be filled with the smell of scorching sulfur.

In such an environment, there is almost no vegetation on the ground to survive, and the few small red grasses grow tenaciously, and the sharp barbed leaves exude a dangerous smell that is not to be messed with.

With a soft glow.

Lin Ran's figure walked out of it.

After two consecutive waves of S-level ratings, he speeded through two dungeons, and finally let him get the permission to enter the secret realm of the target dungeon and came to his final destination.

D-class dungeon secret realm——

[Lava Valley]!

Before entering, the beautiful staff lady in front of the office counter in the guild hall kindly warned and reminded him that even if he had passed through the Slime Forest and the Gray Wolf Camp perfectly with two S-rank ratings, he still needed to be cautious when entering the secret realm of this lava valley dungeon.

In different levels of secret realms, the danger level of the fierce beasts in them has also increased exponentially.

In the gray wolf camp of the E-level secret realm, the mob is the best black iron, the elite monster is bronze, and the highest boss monster is only bronze.

But in this D-class secret realm.

Bronze-level monsters are all running all over the ground, and the stronger elite monsters have already reached the silver level.

There are even boss monsters of silver and even silver top.

It is said that in the deepest part of this lava valley, there may also be a terrifying beast of the gold level.

For the kind reminder of the staff's young lady, Lin Ran just smiled and thanked him.

Of course, he knew the danger.

D-Class Secret Realm.

Basically, only professionals above the three realms are qualified to enter the exploration, if you want to enter the depths of the secret realm and encounter a gold-level fierce beast, then even the masters of the four realms may not be able to guarantee that they will definitely retreat.

Low-level professionals come in basically looking for death.

But Lin Ran is different.

Deep Blue, which has king-level qualifications, is used as the core combat power, plus it also has the [Flowing Gold Bone Shield] after synthesis and enhancement as a means of life-saving.

In this lava valley, as long as you don't exaggerate too much, you will encounter some gold or even platinum-level fierce beasts.

Others, basically, can be solved.

The first thing to do when entering the dungeon is to summon the three skeleton fire spells and dark blue first.

Lin Ran looked at himself and Deep Blue's attribute panel again.

After being promoted to the middle grade of the first realm and the middle grade of black iron respectively, the experience required for subsequent upgrades has obviously doubled, and the last wave of gray wolf camp dungeons has been brushed, which is only enough for him and dark blue to only upgrade by 1 level respectively.

However, the first two rounds of dungeons were full, which made him earn a lot of money on his system energy value.

Counting the more than 800 points that were not used up in the previous lottery lottery.

Now his energy is total.

It has reached 5600 points!

You can open ten more treasure slots in one go!

Huge sums of money!

However, before Lin Ran could figure out whether to open the Lucky Treasure interface and use up the ten consecutive draws in one go, a pop-up window had already popped up on the system interface

[The host's current energy value has accumulated to 5000 points.] 】

[Enable a new feature - material crafting.] 】

Do you want to activate the new feature?

[Yes/No.] 】

......

Synthesis systems are becoming more and more functional.

The lottery category now has a [Lottery Wheel] that is refreshed once a month and a [Lucky Treasure] that opens a grid.

Synthesis types include [Royal Beast Synthesis] and [Skill Synthesis].

Now there's another [Material Crafting].

Activation must be activated, the cost is a full 5000 energy points, Lin Ran still didn't blink his eyes when he clicked the confirmation button, and he didn't feel distressed at all.

The daughter is gone, and when she comes back, this energy value will be there again after a few more copies.

[Congratulations to the host for activating the "Material Synthesis" function.] 】

Clicking on the material synthesis interface on the system panel in front of him, Lin Ran immediately tried to select the bronze-grade fire-based spirit stone he had purchased in the spirit stone market before.

Sure enough, it can be combined!

The rules are simple.

Ten bronze-level fire-based spirit stones, plus 500 energy points as a synthesis fee, can be combined into a silver-level fire-type spirit stone.

[Material Synthesis ......].

[Synthesis complete.] 】

[Congratulations to the host for obtaining 1 silver-level fire spirit stone.] 】

Accompanied by a soft light, a silver-grade fire spirit stone with a whole body red fell into Lin Ran's hand, and there was a faint red light on the surface of the spirit stone, slowly flowing as if molten slurry, and the abundant spiritual power contained in it made people feel refreshed.

Lin Ran tried to put this silver-level fire-type spirit stone into the synthesis checkbox again, and saw that it still needed ten silver-level fire-type spirit stones to synthesize a gold-level spirit stone, and the synthesis cost became 5,000 energy points.

This made Lin Ran dispel his original plan to rely on the material synthesis function to become a rich man.

If you don't use energy as a handling fee.

He really doesn't have to work hard to brush copies, he goes to the spirit stone market every day to buy low-grade spirit stones, takes them to upgrade the brainless synthesis and then sells them, and he can easily become a billionaire.

However, now this situation has also made Lin Ran satisfied enough.

Farming monsters all the way to the dungeon, even if he was unlucky enough to find a gold-level quality fire-type spirit stone, as long as the number of low-level spirit stones and energy value points were enough, he could also rely on the synthesis system to collect 10 gold-level quality fire-type spirit stones.

So.

Next.

It's time to get to work.

Lin Ran beckoned his three Skeleton Fire Law Junior Brothers and Deep Blue, and did not hesitate to kill them into the valley.

Soon he encountered several goblin mobs with red bodies and maces.

Name: Flame Goblin.

[Attributes]: Fire type.

[Grade]: Bronze medium grade.

[Four-Dimensional Attributes]: Strength 65, Agility 45, Spirit 35, Endurance 60.

It is worthy of being a D-class copy of the lava valley, and the first batch of mobs that you encounter casually are already bronze medium-grade.

A few skeleton mages beside Lin Ran rubbed a few fireballs and beckoned.

Three fireballs burst through the air, hitting their targets, and blasting in succession on the first Flame Goblin at the head.

Although the flame goblin was successfully blown to the ground, the other party's carp stood up again, except for the scorched black body, but he was not fatally injured, and his eyes looked towards Lin Ran viciously.

Really.

The three black iron top-grade skeleton fire methods, in this level of secret realm dungeons, the power is no longer enough.

But it was also to be expected.

Lin Ran shook his head and casually greeted him:

"Navy blue. "

"Up. "
