What caught my eye was a transparent door of light, almost exactly the same as what I had seen before. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Through the light gate, you can see the continuous passage, deep and slender, and the steps are like a road to the sky, which is fascinating. Obviously, this is the staircase to the upper level of the Boundary Tower, but it's just ......

It is blocked by a door of light without a layer.

Lin Feng stretched out his hand to touch it, and the invisible force bounced it back, his gaze fell on the transparent colored light door, and ten holes were clearly visible, each of which was in the shape of a crystal tower, which was already obvious.

"To get to the upper level, you need ten boundary tower crystals." Lin Feng muttered softly.

I now have ten boundary tower crystals, and I won't spend it here, because the treasures on the upper level can be imagined, and it is estimated that each one is at least ten boundary tower crystals.

Even if it costs ten Boundary Tower Crystals to enter, it can't be exchanged for treasures.

"Hmm......" Lin Feng pondered.

I now have three Boundary Tower Crystals, and it is obvious that I must spend them, because it is still unknown whether I will come to this Boundary Tower again next time. His gaze fell on the corridor on the left, Lin Feng thought in his heart, and then started to explore again.

The entire Boundary Tower layer is in the shape of a ring.

I used to explore from the right side, but the left side did not explore, maybe that side ......

Have a more attractive treasure?

With curiosity and anticipation, Lin Feng continued to explore, the light of the Qianhe River was extremely attractive, for Lin Feng now, the best treasure in this layer was the light of the Qianhe River, which was difficult to see outside.

Before he was in Tang Xuan's territory, the breakthrough of the bloodline of light was vivid.

The light of the river here has 1 realm tower crystal, 2 realm tower crystals, and 3 realm tower crystals...... The highest is the 5th Realm Tower Crystal!

"The light of the Qianhe River of the 5 Realm Tower Crystal is comparable to the light of the Qianhe River in the source light realm!" Lin Feng was very sure, because he had absorbed it, and he would break through the path of light with one!

From the realm of small success to the realm of great success!

It contains the most extreme element origin, the essence of the river!

"The light of the earth of the 3 Realms Tower Crystal, the earth essence contained in it is estimated to be only fifty percent of the 5 Realms Tower Crystal, even if the Tyrannosaurus Rex doppelganger earth qualification is excellent, I am afraid... It is also difficult to ascend to the realm of Dacheng. Lin Feng frowned slightly.

On the deity, whether it is the path of light or the path of the speed of light, the Dacheng realm is even more difficult to break through.

High can't be, low can't.

It's a bit of a waste to exchange it like this, but if you don't exchange it, what else is worth exchanging?

Fruit of Heaven and Earth?

Lin Feng pondered in his heart, after all, although there were few Heaven and Earth Fruits in the Qianhe River, there were many on the land outside, unless it was urgently needed, otherwise it was not worth exchanging Heaven and Earth Fruits here.

"There's still half a way to go, I'll talk about it all after reading it." Lin Feng was worried.

Continue to explore, and don't rush to make a decision, anyway, there is still time and effort. One crystal ice sculpture after another fell into his eyes, Lin Feng didn't miss any of them, and soon-

is nearing the 'end'.

Or rather, the starting point, where the transparent color gate is located.

"It's a bit wasteful, but at least it's better than the others." Lin Feng muttered softly, he had already made a decision in his heart, and he could already see the light gate he had entered in the distance, which was very similar to the one at the end, and he was about to turn around to exchange the light of the earth and the river, Lin Feng's eyes flickered, and he stopped.

Not far away, there was a strange black tower-shaped object, which was completely different from the boundary tower crystal.

It's bigger, it's thicker, and the color is different.

Never seen before.

What is it?

Lin Feng was curious, and his eyes swept around, there were not many such black towers, which were staggered near the entrance light gate, and the position of the crystal of the exchange boundary tower on the right side was very similar.

To be precise, it should be symmetrical.

"It should be a commonly used treasure." Lin Feng secretly thought in his heart, the other crystal ice sculptures all existed alone, but the exchange of the Black Tower and the Boundary Tower Crystal was plural, and there were quite a few of them.

One black and one white, even more symmetrical with each other.

"It's not a black bead exchange." Lin Feng knew that there was no gap in this black tower, but it needed energy crystals to exchange, no more, no less, just three energy crystals.

As for the black beads, I don't have one on my body, although there are many outside, but in fact, they are scarce.

Because the ratio of black beads to white beads is closer and closer to the back, it will only be the white beads remaining, not the black beads remaining.

"Hmm......" Lin Feng pondered, looking at the Black Tower, uncertain.

Now the choice left to yourself is clear, either exchange for the light of the river of the earth type, or... It's to exchange for this useless Black Tower.

One is more secure, the other is more adventurous.

"This black tower must be useful, but I don't know how to use it." Lin Feng looked at the Black Tower with deep eyes, and intuitively told himself that it was a better choice to gamble now.

After all, even if the light of the Earth and the River that was exchanged for the three energy crystals, it could not cause the Tyrannosaurus rex clone to have a fundamental transformation.

The inability to transform into a Buddha-figure is not necessary.

"That's it." Lin Feng made a decision.

The 'full wealth', three energy crystals were inlaid into one of the crystal ice sculptures, and as the energy crystals bloomed, the ice sculptures flashed through cracks in an instant, cracked and shattered, turning into crystal light and dissipating.

In front of him, the black tower fell into his hands.

Wow~~

Lin Feng's eyes suddenly lit up.

In the induction, clear information came into his mind, telling him how useful the Black Tower was and how to use it, the corners of Lin Feng's mouth drew a slight arc, and then took the Black Tower into his pocket.

"Good luck." Lin Feng smiled and left the Boundary Tower, satisfied.

I made the right bet.

……

There's still a year to go!

Basically, the elimination of the first King Hall Tianguan has been carried out seventy-seven-eighty-eight.

The Qianhe Demon Clan that should have passed has already passed, and those who have not passed have either entered late, or are 'dying'. The rest are generally weaker, and even if they are lucky enough to enter the second level, they will be eliminated.

Lin Feng, in fact, is not much worse.

The Tyrannosaurus rex clone is only the strength of the intermediate Black Domain Master, and the first King Hall Heavenly Pass can be easily passed because the Black and White Qiqi Beast is only the combat power of the primary Black Domain Master, and the Stream Guardian is only the peak of the primary Black Domain Master.

His strength is just above it.

However, if you enter the second level, the difficulty will increase by one level.

"Whew!" "Boom!" "Peng!"

The Tyrannosaurus rex doppelganger moved extremely fast, the tail covered with scales and thorns swung out, and its claws were cut like knives, and the white Qitaki beast was directly killed, taking its white beads, and this kind of killing has lasted for a year since the return of the Boundary Tower.

For Lin Feng, it was easy to kill the White Qiqi Beast, and he had the right to practice the sword.

Today, there are less than three days left before the five-year deadline.

"Almost." Lin Feng cleanly killed the last three white Qiqi beasts, revealing a smile.

Just right!

Wow~~

Taking out the black tower, Lin Feng's eyes were bright.
