As early as after a year's recuperation injury, when the two met again outside Starfall City, Wu Xiang had already vaguely had some speculations about Fei Ran's strength improvement.

At that time, the two of them were just testing and testing each other through momentum, and they did not show their real strength, and what they showed was only the tip of the iceberg of their own strength.

Moreover, the aura collision that erupted in the middle attracted the blood of the Blood Knife Gate, adding a great danger, so he did not continue to try.

In fact, there was not much need at that time, with the two sides understanding each other for many years, the confrontation during this period of time has already sensed from the breath that the strength of the other party has not fallen due to the recuperation of the injury, and a lot of changes have occurred.

And this is actually an important reason why they are willing to put aside each other's prejudices again and choose to work together to enter this deep underground.

In this year's recuperation and healing, the two of them had accumulated enough cultivation in the Sky Realm, and now they only needed to collect the breakthrough resources needed for the breakthrough before they could start trying to break through the retreat.

They both want to kill each other right away, so as to settle the grievances and grievances accumulated over the years, and at the same time, they can also seize the accumulation of each other over the years to make the best preparations for their breakthrough.

If it is found that the other party's cultivation strength has not improved significantly, or the other party's injuries have not healed, they will not hesitate to attack each other and fight to the death.

Therefore, on the surface, that meeting was only an appointment between the two sides, a negotiation meeting between the two sides that wanted to cooperate, but it was rather a dangerous invisible game.

As long as in the meeting at that time, either side failed to show its own strength, failed to attract the jealousy and suspicion of the other party with its own strength, and was hit by the other party as if it were fatal.

But in this game, they did not give up the idea of the treasure of chance contained in this underground space, and they always remembered what the two of them discovered a year ago.

It's just that joining forces a year ago is still a thing for them to live for, and the distrust and scheming between each other are still difficult for them to truly believe in each other.

Moreover, if we only speculate from the situation a year ago, after a year of changes, the underground space is probably much more dangerous than a year ago.

Therefore, they know very well that if they want to seize the treasure that can make them successfully break through from here, it is difficult to do it with their own strength, and the chance is so-called slim.

What's more, there are now unexpected members of the Blood Knife Sect intervening, including the existence of the Blood Knife Sect Elder, Blood Li.

With this strong man with the same cultivation as them eyeing him from the sidelines, even if they could personally succeed in seizing the treasure, it would be difficult to hide the clues from him.

At that time, there will inevitably be a big battle that will affect the entire Starfall City, and the Blood Knife Gate is more likely to take advantage of this as an opportunity to officially enter the Starfall City.

Under the combination of all kinds of thinking and strategies, this is the scene where the two of them are now entering this underground space together, and there is also the reason for the appearance of the battle in front of them.

.......

As the billowing smoke and dust gradually dissipated, Wu Xing, who was hanging in the air, couldn't help but be awe-struck in his heart, and pondered in his heart: "A year ago, a small beast that was in a state of mortality in Fei Ran's hands was not only able to survive, but also showed such a powerful strength, it seems that after a year of development, many unknown changes have taken place in the depths of the underground again."

"But that also means that that thing is indeed powerful, and if I can get it on this trip, then .....," thought in his heart, and soon his slightly condensed eyes flashed with unconcealed excitement and excitement.

This kind of change and fluctuation between moods Wu Xing was well hidden, and Fei Ran, who was staring at the smoke and dust, did not feel it, but this did not prevent him from detecting this from the changes in his body when he glanced at Wu Xing.

"It is worthy of a rare treasure in legends, and its effect is really powerful enough, and it can raise this evil animal to such a level in just one year", he was also sighing and excited in his heart.

Every time he thought of the treasure hidden deep in this place, the emotions in his heart became more and more excited.

"Fortunately, I have always hidden a hand in doing things, Wu Xing, Wu Xing, if you don't die on this trip, I can't be at ease."

At the same time, when he thought of Wu Xing, who had entered this place with him on this trip, the malice towards Wu Xing in his heart also arose, and he made up his mind in his heart.

The speed of dissipation of the smoke and dust was very fast, and it had dissipated nearly half of it in just the time when the mood of the two of them changed, leaving only a cloud of condensed smoke and dust floating in the air.

At this time, I was able to see how terrifying Fei Ran's blow was, only to see a unique crater appear in the sunken ground directly below this cloud of smoke.

The crater is up to five meters deep, and its edges are irregular, gradually revealing as the smoke clears.

This is the crater formed by the strong impact of the air caused by the explosion under the blow of Fei Ran.

"Sizzle"

However, the eyes of the two of them were not here at this time, but stared at the smoke and dust that suddenly came from a familiar sound in the air, and their faces became more and more solemn.

The sound is getting louder and louder, and at the same time, the speed between the throughput is getting faster and faster, and you can clearly feel that there is no sense of weakness at all.

"Could it be .....", a thought flashed in the hearts of the two people who heard this, and Fei Ran had an emotion in his heart that had not appeared for a long time - fear.

This kind of emotion has long been abandoned by him, and after years of fighting and fighting, he has long forgotten what it was originally like, not to mention that he is now invincible in the Starfall Land.

It was really difficult to make him feel such emotions, and in the entire Starfall Land, perhaps only when he was close to life and death with Wu Xing would he flash by chance.

It's just that the changes in psychology may make it difficult to return to the physical reaction, but in Fei Ran's instinctive consciousness, he has already reached the arrival of danger, and subconsciously strengthened the protective light shield outside his body.

Fei Ran, who was just about to retreat sharply behind him, was quickly forced to stop by a touch of danger from the depths of his heart, the cold hairs on his back stood up, and his body tensed up in an instant.

"I want to see a little evil animal, and I really want to turn the sky upside down?"

After stopping, he also sensed the faint danger coming, no matter how he dodged, he couldn't get rid of it, under such a stimulus, Fei Ran drank in his heart, and then a ruthless light appeared in his eyes, staring closely at the smoke and dust rolling in mid-air.

And at this moment, a shadow like black lightning flashed away from the smoke and dust, and in the blink of an eye, it appeared in front of Fei Ran.

When he was solemnly concentrating, a bloody mouth full of blood and the smell of blood had already bitten down on him.
