Xiao Yan underestimated Zhao Letian too much.

Before entering the Imperial Secret Realm, Zhao Letian already knew that many people wanted to kill him here; how could he not be on guard?

In fact, when he was with these people, Zhao Letian was always highly vigilant, never letting his guard down for a moment.

Even if it wasn't for the fact that they hadn't finished exploring the most important palace and didn't want any complications, without these people making a move, Zhao Letian would have taken the initiative to deal with them, not giving them any opportunity at all.

Xiao Yan wanting to ambush Zhao Letian was simply too naive.

Furthermore, even if Zhao Letian had no precautions, Xiao Yan wouldn't have succeeded.

Because the Golden Flood Dragon following Zhao Letian was also on alert at all times, ready to protect Zhao Letian at any moment.

In fact, the moment Xiao Yan made his move, the Golden Flood Dragon had already sensed it and was prepared to stop Xiao Yan's attack.

However, he didn't expect that Zhao Letian's reaction would be even faster. He personally made a move, and thus there was no need for the Golden Flood Dragon to act, believing that with Zhao Letian's strength, blocking Xiao Yan's attack would be no problem at all.

"Boom!"

The next moment, the blade light met the Sword Qi, causing a terrifying shockwave that blasted the surrounding people away, and the result was that the Red Flame Blade Light only lasted a moment before it was shattered by Zhao Letian's Invincible Sword.

"Micro Realm Sword Force, Micro Wind Force, Micro Fire Power, Micro Thunder Force… and moreover, fused so perfectly, the realm of unity of Dao and martial arts is hard to estimate, what a frightening person!"

Feeling the terrifying power in Zhao Letian's Invincible Sword, the people on site couldn't help but show a shocked expression.

Even Ji Pengyu and others all frowned, showing an unprecedented solemn expression in their eyes.

When Zhao Letian made his moves earlier, he did not show much strength, and everyone only saw the tip of the iceberg, unable to determine his exact level of strength, but now, through this sword, everyone immediately discerned much information. The more they saw, the more they despaired, still unable to see the upper limit of Zhao Letian's strength.

At the same time, Zhao Letian's Invincible Sword continued unabated, directly slashing towards Xiao Yan behind.

"Hmph! Who would have thought that your strength has reached such heights, but even if I can't kill you, you likewise can't do anything about me, young master!"

Seeing the ambush fail, Xiao Yan frowned, disappointment in his eyes, but he confidently spoke.

"Boom!"

As soon as his words fell, Xiao Yan's body suddenly turned into a Fire Cloud, rapidly spreading.

"Tsst!"

Almost simultaneously, Zhao Letian's Invincible Sword slashed across, directly passing through the Fire Cloud.

"Hmph!"

The next moment, a pained grunt came from the Fire Cloud, and then with a flash of light, Xiao Yan's body reappeared.

But at this moment, Xiao Yan's complexion looked somewhat pale, his expression very painful.

Clearly, though the sword just now did not kill him, he was not completely unharmed; he still suffered heavy injuries.

"Damn it, my Acquired Fire Spirit Body has just formed, and I'm still not adept at using it, otherwise he wouldn't have been able to injure me!"

Xiao Yan thought very vexedly.

"Hmm?"

At the same time, Zhao Letian, who was walking ahead, also frowned, stopping his steps, turning around, and looking at Xiao Yan with some surprise.

He originally thought that with that sword just now, it would be easy to slay someone like Xiao Yan, who was nothing but trash.

Unexpectedly, Xiao Yan's body underwent a special transformation, allowing him to escape by a stroke of luck.

"Could this be the legendary special physique?"

Zhao Letian asked the Golden Flood Dragon through spiritual transmission.

The condition Xiao Yan was in just now resembled some Fire Spirit Bodies described in the heritage memories of the Dragon Clan, but it was slightly different.

"Calling that a special physique? Hmph, it's nothing but an artificially crafted product, and the method used is very crude, just a superficial appearance and not worth mentioning at all. It's not comparable to a true special physique!"

The Golden Flood Dragon disdainfully said.

"So that's how it is!"

Zhao Letian thought to himself, no wonder Xiao Yan's condition seemed dubious; it turned out to be a mere poor imitation.

Since that was the case, things would be easier.

"God Destroying Sword!"

The next moment, just as Xiao Yan thought he was safe and prepared to continue ascending the path to the heavens, Zhao Letian suddenly shouted coldly. A transparent Divine Thought Sword shot out from between his eyebrows at an unimaginable, terrifying speed, heading straight for Xiao Yan.

"A Divine Thought Attack? Oh no!"

Watching the Divine Thought Sword rapidly enlarging in his pupils, Xiao Yan's face drastically changed.

"Shhh!"

Caught off guard, Xiao Yan couldn't react in time and could only watch helplessly as Zhao Letian's Divine Thought Sword went straight into his glabella and surged into his Divine Soul Space, annihilating his Divine Soul!

After that, with a loud 'bang', Xiao Yan's corpse, like a watermelon, was directly burst open by the terrifying pressure on the path to the heavens.

"Hiss!"

Witnessing this scene, everyone couldn't help but inhale a breath of cold air, their looks toward Zhao Letian filled with deep wariness.

With just a single Divine Thought Sword, Zhao Letian could kill an invincible expert; his strength was simply too terrifying!

Simultaneously, Ji Pengyu and others also felt a strong shock again.

They asked themselves, if it were them, they definitely couldn't effortlessly slay an invincible strong person like Zhao Letian.

At this moment, Zhao Letian's strength had utterly exceeded their understanding. If it wasn't well-known that in this Small World, one's strength couldn't surpass the True Martial Realm, they would even suspect that Zhao Letian was a terrifyingly strong person who had hidden his real strength.

However, the people did not know that Zhao Letian's Divine Thought Power was naturally far superior to his peers. Coupled with the God Destroying Sword, a very terrifying Divine Thought Secret Technique, the God Destroying Sword wielded by him could easily kill even those in the Initial Stage of the Sect Martial Realm, and even pose a threat to those in the Middle Stage of the Sect Martial Realm. Killing a mere True Martial Realm individual was naturally not a difficult task.

Moreover, the previous Invincible Sword had already severely injured Xiao Yan, and with Xiao Yan being momentarily careless, this allowed Zhao Letian to instantly kill him.

Otherwise, if it were a well-prepared, in-good-condition invincible strong person, Zhao Letian would find it difficult to instantly kill the opponent just with a Divine Thought Attack.

"Swoosh!"

As everyone was shocked, Zhao Letian waved his hand and directly collected the Storage Ring that burst from Xiao Yan's body, then turned around as if nothing had happened and continued to climb the path to the heavens.

After this battle, those who still harbored ill intentions would definitely not dare to act rashly again.
