At this time, outside the tower, night had fallen.

There is no bright moon in the canopy tonight, only sparse stars dotted among them, and the sky is dark.

But no one left the Remnant Yang Square, and everyone was looking forward to Du Yu's successful customs clearance and witness the birth of a miracle with him!

Du Yu entered the No. 2 Remnant Sun Tower, and half an hour had passed.

There was no vision in the tower, but with Du Yu's previous experience of clearing Tower 3 in an hour, no one felt anxious for the time being.

At this time, after a difficult battle, Tanedu finally killed the spider beast.

Although he successfully killed the spider beast, the mana stored in the dantian was also consumed, and his physical strength was also seriously overdrawn.

According to his situation, it is already the limit to be able to kill one more transformation beast, so what about the remaining 99 beasts?

Does it fail like this?

Du Yu is very unwilling!!

But what can be done to turn the tide and turn the tide? ?

His biggest reliance is on the system, but the system won't help him fight, nor will it give him duplicate points out of thin air.

In the face of absolute strength, he has exhausted his donkey skills, and it seems that all he is waiting for is the result of failing to clear the customs.

The illusion beast didn't matter what Du Yu thought, after the death of the spider beast, a python-like beast immediately rushed over and launched an attack on Du Yu!

Du Yu, who had not yet breathed a sigh of relief, faced the attack of the python beast, and stabbed the python beast with a sword like a reflex.

"Poof!"

The blue light sword sank into the python's fierce beast seven inches without hindrance.

After struggling for a few moments, the python beast turned into countless points of light and disappeared.

"This ......"

He ...... He killed the python beast with a single sword??"

Looking at the python beast that disappeared into a point of light, Du Yu was directly dumbfounded, thinking that he was hallucinating!

If these transfiguration beasts were so easy to kill, he would have cleared the level a long time ago, and he would have fought with the spider beasts for half an hour, and finally he was physically and mentally exhausted!!

If it wasn't a hallucination, what did he just do?

Du Yu immediately recalled the moment of the battle with the python beast just now......

Suddenly, Du Yu's eyes lit up, could it be......

"Uhhh

Du Yu stabbed at the illusion beast that filled the position again, and the strange scene appeared again.

The fierce beast that filled the position was pierced by his sword, struggled a few times, and disappeared into countless points of light.

"Haha!!"

Du Yu laughed excitedly, and the whole thing was countless times easier, after understanding the reason.

Now don't talk about 100 two-star transformation beasts, even if it's a thousand, he can easily solve it.

It turns out that this is the secret of customs clearance, once you know the secret, even those who are less talented can pass through two or three Remnant Sun Towers.

What did he just do?

Just one thing, he used the "Remnant Sun Sword Technique"!!

When he was fighting against the python beast, he unconsciously performed the second form of the Remnant Sun Sword Technique, and the python beast died.

When he was fighting to fill the fierce beast, he deliberately performed the second style of the Remnant Sun Sword Technique, and a sword penetrated, and the fierce beast died.

To sum it up, it can be summed up in one sentence: the Remnant Sun Sword Technique is the nemesis of these illusion beasts, no matter how high or low the strength is, they are all scum in front of the "Remnant Sun Sword Technique"!

"Poof!"

"Poof!"

......

A few more transfiguration beasts were solved by Du Yu's sword, and there was no mistake at all.

Under Du Yu's careful observation, he found that when he cast the Remnant Sun Sword Technique, the dark red light that filled every inch of space in the tower would attach to his blue light sword, forming a thin layer of red light.

It was this layer of red light that ignored the defense of the transformation beast and was directly killed by him with a single sword!

The trial of this Remnant Sun Pagoda was originally intended to be used to cultivate the "Remnant Yang Heart Method" and the "Remnant Sun Sword Technique", the heart method cannot be achieved overnight, but the sword technique can be learned and used by some geniuses.

Moreover, the strength of the transformation beasts in the first five Remnant Sun Towers from 10 to 6 is very low, and they can be killed even without the "Remnant Sun Sword Technique".

The purpose is to familiarize yourself with and practice the "Remnant Sun Sword Technique", and the last five Remnant Sun Towers are the real trials, and the content of the trials is the "Remnant Sun Sword Technique"!

Why have countless people participated in the trials of the Remnant Sun Tower for hundreds of years, but none of them discovered the secret?

The reason is very simple, when fighting, whoever chooses the swordsmanship that he has just mastered is definitely using the martial arts he has learned before.

Du Yu was no exception, all the way over, the transformation beast in front was too weak, not to mention, with the increase in the strength of the transformation beast, he used the blue light sword, but he used the "Fire Spirit Sword Technique" instead of the "Remnant Yang Sword Technique" he had just gotten.

If it weren't for the accident just now, the secret still wouldn't have been discovered, and the road to customs clearance would have stopped here.

If he didn't use the "Remnant Sun Sword Technique", Du Yu could be sure that no matter what kind of genius he was, he would definitely not be able to clear all the ten towers in the Qi Cultivation Realm, including the Foundation Building Realm.

It is precisely for this reason that no one has been able to clear all of them for hundreds of years, and it has nothing to do with how powerful the talent is.

The key is whether you know the secret, otherwise everything will be in vain!!

Knowing the secret, Du Yu, who has mastered the four-style "Remnant Sun Sword Technique", is like a fish in water.

One sword kills a transfiguration beast in seconds, if one sword doesn't work, it's two swords!

Under the two swords, the fierce beast will surely turn into a point of light and disappear.

In less than half an hour, the remaining dozens of fierce beasts in the tower were all emptied, and the spirit stones fell to the ground.

A fierce beast dropped a spirit stone, which was all Du Yu's trophy.

With all the spirit stones included in the space ring, the remnant sun tablet resurfaced.

Under the systematic viewing, the information of the Remnant Sun Monument was displayed in front of Du Yu in the form of a panel.

Name: Remnant Sun Sword Technique (Fifth Style).

Grade: The top of all grades.

Replication points required: 5.

Seeing that the "Remnant Yang Sword Technique" on the Remnant Yang Tablet was not the "Remnant Yang Heart Method", Du Yu was stunned.

According to the No. 10 tower is the "Remnant Yang Heart Method", and the No. 9 tower is the "Remnant Yang Sword Method", then the No. 2 tower should be the "Remnant Yang Heart Method"!

How did it become the "Remnant Sun Sword Method", but instead put the last layer of the "Remnant Sun Heart Method" in Tower 1.

Or does it mean that "Remnant Yang Heart Method" only has four layers, and there is no fifth layer?

If this is the case, then the "Remnant Yang Heart Method" that was guessed before has a total of five layers, corresponding to the five realms of cultivation, which is not right.

If Tower 1 wasn't the Remnant Sun Heart Method, what would it be in?

No one in the entire Remnant Sun Academy could answer this question, and only when Du Yu personally entered Tower 1 and cleared the customs could he know.

Regardless of whether the guess is right or wrong, copy the "Remnant Sun Sword Technique" first.

"Copy the fifth form of the Remnant Sun Sword Technique. Du Yu said in a deep voice.

"Ding! Copy the fifth form of the "Remnant Sun Sword Technique" successfully, and consume copy point 5. ”

The content of the fifth form of the "Remnant Sun Sword Technique" appeared in Du Yu's mind, turned into a streamer and fused into his consciousness, becoming his martial art.

"Ding!Successfully clear Tower 2 and get 10 copy points. ”

With the sound of the system sounding in Du Yu's mind, the No. 2 spire, the red glow bloomed, shining in the night sky, beautiful and bright!
