"This is the Boundary Tower. Pen & Fun & Pavilion www.biquge.info"

"The first time you enter, you can get the 1 Realm Tower Crystal."

"Consuming the Boundary Tower Crystal, you can get all the treasures you want in the Boundary Tower......" The old man's voice sounded in his ears, reverberating around the entire giant tower that seemed to be condensed into crystals.

Lin Feng's eyes were shining.

Looking at a thumb-sized tower-shaped crystal in front of him, he smiled.

No matter what the effect of this 'Boundary Tower Crystal' is, at least the secret of the first King Hall Heavenly Pass has been cracked, as I guessed before, at least ten dark cloud streams, and indeed have their intentions.

"The Boundary Tower......" Lin Feng murmured softly.

Is this related to the Qianhe River?

Looking around, everything here is nothing special, but the crystal tower like a mountain in front of him stands tall, Lin Feng put away the boundary tower crystal, and walked forward, the boundary tower made of crystal in front of him towered into the clouds, and he couldn't see the top.

In front of this Crystal Realm Tower, everything is so small.

There was a transparent colored light door on the crystal wall in front of him, Lin Feng reached out and touched it, but an invisible elastic force turned him away.

Well?

Lin Feng's heart moved, and his gaze fell on the top of the transparent colored light door, and a tiny hole like a crystal tower fell into his eyes.

"It seems that this is the reason for giving me the Boundary Tower Crystal." Lin Feng smiled and pressed the only piece of Boundary Tower Crystal into the gap of the transparent light gate, and in an instant, the gate condensed and flowed away, gurgling like water.

Suddenly, the 'snap' is gone.

The Tower of the Boundary, open.

"Consume the Boundary Tower Crystal, and you can get all the treasures you want in the Boundary Tower." The old voice from before appeared in Lin Feng's mind, and he couldn't help but laugh.

Originally, he still had a boundary tower crystal, but now there is nothing left.

Even if you open the secret of the first level and come to this strange Boundary Tower, but there is no Boundary Tower Crystal, what will you change?

Swish~~

Entering it, such as entering a crystal treasure mountain, all kinds of strange treasures fall into the eyes, all kinds of mixed hole treasures, all kinds of different colors and forms of the light of the river, full and round, containing deep energy of the fruit of heaven and earth.

Each piece is frozen in ice, turning into a crystal sculpture.

Underneath the crystal sculpture, there are concave holes, exactly the same as the transparent light door on the outside before, with only one hole at the least, and two, three, four, or even five at the most.

And that's just the tip of the iceberg.

Lin Feng's gaze swept over, the deep crystal tunnel contained countless treasures, but the problem was ......

Without the Boundary Tower Crystal, nothing can be exchanged.

"There's no reason, it's impossible to enter Debao Mountain, but I won't give you anything." Lin Feng understood in his heart, and immediately looked inside, if this was the case, there was no need for the first level to be so hidden.

I only took a few steps inside, and soon my eyes lit up.

It was a very different form from the crystal ice sculpture, a huge crystal tower, tall and majestic, very similar in appearance to the boundary tower crystal, but it was empty inside.

Lin Feng was lightly surprised, looked up and down the crystal tower, and smiled.

I see.

The light flashed in his hand, took out the white beads, and fell towards the only gap at the top of the crystal tower, the 'small' circular notch, just enough to accommodate the white beads to enter, as if squeezing into it, as the white beads fell, it suddenly turned into a light white light, melting in the crystal tower.

One after another.

Until the 10,000th was counted, the light turned from white beads filled the entire crystal tower, and the empty crystal tower became saturated and perfect.

A white rainbow streaked by, and the phantom light flowed, enveloping the crystal tower.

Strange energy entanglement, the huge crystal tower shrank sharply in an instant, the energy continued to increase, perfectly integrated, and soon turned into the boundary tower crystal.

"The first piece." Lin Feng smiled and took it in.

When he first entered the Tianguan of the Royal Palace, the ratio of black beads to white beads was 15:1, and then 10:1 and 8:1, gradually shrinking, and finally it was close to the ratio of 3:1.

Therefore, when 1.1 million black beads were collected, the number of white beads reached 140,000.

After that, the door of yin and yang was opened, 110,000 were consumed, and more than 30,000 were left.

"A total of three Boundary Tower Crystals can be exchanged." Lin Feng quickly found the second crystal tower, and once again fused ten thousand white beads into it, turning it into a boundary tower crystal.

In a short time, all the redemptions were completed.

There are three boundary tower crystals in his palm, which can be exchanged for three 'ordinary' treasures, or a 'good' treasure, Lin Feng has traveled along the way, and he also has some knowledge of the treasures that can be exchanged for the boundary tower crystals.

The most of them is the Mixed Cave Treasure.

Therefore, the value of the Mixed Cave Treasure can be known at a glance.

"1 Boundary Tower Crystal can only be exchanged for a low-grade top-grade Mixed Hole Treasure."

"2 Boundary Tower Crystals, exchange for a medium-grade top-grade Mixed Hole Treasure."

"3 Boundary Tower Crystals, exchange for a top-grade Mixed Hole Treasure."

"5 Boundary Tower Crystals, exchange for a top-grade Mixed Hole Treasure."

It's easy to tell.

In itself, there are only the light, thunder and earth of the origin of heaven and earth, the two qi of yin and yang, and the five elements of water and wood.

"It's not very useful." Lin Feng continued to walk inside.

Or, to put it more bluntly – it's useless.

There are so many mixed hole treasures on his body, and there are a lot of peak mixed hole treasures alone, so how can he care about the top mixed hole treasures?

However, for the other demon clans, it is precious.

Originally, there were few mixed cave treasures in the Tengqi Continent, not to mention the Qianhe Demon Clan, and there were even fewer in the Qianhe River, and a top-level mixed cave Xuanbao was enough to make a group of Xiaohe Demon Clans who controlled the Black Domain snatch their heads.

But here, there's a whole bunch of them!

As long as you have enough Boundary Tower Crystals, you can exchange them!

"This Boundary Tower is not ordinary." Lin Feng sighed in his heart, although he was not interested in the Mixed Cave Treasure, but there were not only Mixed Cave Treasures here, but the light of the Qianhe River, which contained light, earth, and thunder, was very useful to him.

All kinds of heaven and earth fruits are also rare treasures.

However, there are only three boundary tower crystals, and even if they are in Baoshan now, they can only dig a corner of Baoshan.

"It would be nice to have." Lin Feng didn't care either.

Compared with other demon clans, this is the first Heavenly Pass of the King Palace, and he has already made some gains, and he is content and happy.

It was still a long time limit of five years, but there was no hurry, Lin Feng wandered around the 'Baoshan' slowly, hoping to dig up some good things.

Although there are only three boundary tower crystals, as the saying goes, no matter how small a mosquito is, it is still meat.

When it is to make the best use of things.

Slowly deepening, the Boundary Tower is not small, but it is not big.

Soon, it came to an end.

"Oh?" Looking into the depths of the end, Lin Feng's pupils couldn't help but light up.
