This was a Rank 4 spiritual protection spirit tool, which The Hongchen Siblings originally didn't intend to use.
However, although their martial soul fusion skill was very strong, it still couldn't block the complete Sun Moon Divine Pupils.
If they didn't use this spirit tool, they wouldn't feel good once Xu Tianzhen's full-strength strike landed.
The moment the spirit tool was used, the sea of consciousness that had been frozen was suddenly protected and returned to normal.
The giant toad resumed its movement, and its terrifying spirit power suddenly erupted. With a powerful force close to the level of a Spirit Ancestor, it forcibly obliterated the Sun Seal.
The Sun Seal was forcibly erased by a massive amount of spirit power, and the True Fire of the Sun that was originally burning on the surface of the giant toad also suddenly disappeared.
In an instant, the giant toad opened its mouth toward the falling sun and spat out a breath of freezing air.
"Whoosh—"
The sun from Xu Tianzhen's full-strength strike collided with the freezing breath. The power, close to that of a Spirit Ancestor, directly froze the falling sun, neutralizing Xu Tianzhen's attack.
If they relied solely on their martial soul fusion skill, The Hongchen Siblings would indeed have a hard time dealing with the joint attack of Xu Tianhao and Xu Tianzhen.
But besides being genius Spirit Masters, they were also top-tier Soul Engineers.
Although this Rank 4 spiritual protection was not made by them, as long as they could use it, it could serve as their trump card.
This was a demonstration of the combination of Spirit Master and Soul Engineer, maximizing one's strength.
However, as a result, the spirit power of [Hongchen Nostalgia] was also being consumed rapidly. At this stage, The Hongchen Siblings couldn't hold out for too long.
Activating a Rank 4 spiritual protection spirit tool was a huge drain on their spirit power.
So they had to take this opportunity to quickly take down Xu Tianhao and Xu Tianzhen.
After resolving Xu Tianzhen's full-strength strike, the giant toad opened its huge mouth again and spat out a mouthful of Ice Toad Poison mixed with ice and fire energy toward Xu Tianhao and Xu Tianzhen.
This was the power from the Vermilion Eye Ice Toad.
The Vermilion Eye Ice Toad is a special Spirit Beast from the Far North, known as the king of the crevices, and is a powerful Spirit Beast possessed of lethal poison.
The Vermilion Eye Ice Toad itself is of the ice attribute, but its pair of crimson eyes are of the fire attribute.
The combination of ice and fire formed an extremely terrifying ice-fire poison.
Facing The Hongchen Siblings' poisonous attack, Xu Tianhao and Xu Tianzhen glanced at each other, but they did not panic.
Since The Hongchen Siblings could use spirit tools, the two siblings naturally could as well.
After all, among those of the same level, they were also top-tier Soul Engineers.
Just as The Hongchen Siblings were wary of Xu Tianhao's Sun Moon Divine Seal, Xu Tianhao and Xu Tianzhen were equally wary of Meng Hongchen's poison.
Xu Tianhao and Xu Tianzhen suddenly stood in a line. Xu Tianzhen placed her hands on Xu Tianhao's back, giving him all her remaining spirit power.
Xu Tianhao took out a fist-sized circular glazed bead from his spirit tool.
This was a Rank 3 defensive spirit tool. Its main effect was to defend against lethal poison, while also possessing a certain degree of defensive capability.
Under the infusion of spirit power, the glazed bead erupted with brilliant light, forming a glazed shield with a diameter of three meters around the siblings.
The glazed shield not only blocked the poison but also blocked the accompanying spirit power impact.
At the same time, the spirit tool on Xu Tianhao's left hand flashed again, and a two-meter-long spirit tool cold weapon spear appeared in his hand.
After the spear appeared, under the infusion of Xu Tianhao's spirit power, it actually transformed directly into a thermal weapon spear.
The name of this spirit tool was the brilliant dragon spear, and it was given to him by his eldest brother, Xu Tianran.
spirit tools named after [Huang Long] were a whole set of inherited spirit tools, and only the heirs of the Empire were allowed to possess and use them.
They were the amplification-type Huang Long Armor, the defensive-type Huang Long Shield, the offensive-type brilliant dragon spear, the auxiliary-type Huang Long Pendant, and the flying Huang Long Wings.
It was a top-tier spirit tool set that covered almost every aspect of a Spirit Master, and it was a complete series from Rank 3 to Rank 9.
Originally, except for the Rank 9 huang long set, the rest were in the hands of the current Crown Prince, Xu Tianran.
However, Xu Tianran was now at the cultivation level of a Seventh Ring Soul Sage. The huang long set below Rank 7 was of little use to him, so he gave them all to his younger brother, Xu Tianhao.
As a brother from the same mother, Xu Tianran had no reservations toward his brother, breaking the rule that only the heir could use the huang long set.
Emperor Xu Jilong naturally had no objection to Xu Tianran's actions.
Each rank of the huang long set was an absolutely top-tier spirit tool at its level. With the enhancement of the huang long set, Xu Tianhao's strength could be greatly improved.
In this regard, Emperor Xu Jilong was also willing to see it.
Moreover, seeing the two brothers so close and harmonious was what Emperor Xu Jilong desired most.
Unfortunately, as the highest-tier inherited spirit tool, the lowest rank of the huang long set started at Rank 3.
With Xu Tianhao's current spirit power foundation, even for a Rank 3 huang long set, his spirit power was not enough to support using all of them.
At this moment, with the enhancement of Xu Tianzhen's spirit power, being able to use the brilliant dragon spear was already his limit.
But as soon as the brilliant dragon spear came out, there was basically no suspense about the result.
Under the infusion of Xu Tianhao's spirit power, a scorching light instantly erupted from the muzzle of the brilliant dragon spear, heading straight for the giant toad.
As a top Rank 3 spirit tool, under Xu Tianhao's full activation, the power of this strike actually faintly reached the level of a Four-Ring Soul Ancestor!
"Huang Long Ray!"
The giant toad's movements were not slow either. After Xu Tianhao used the Rank 3 spirit tool glazed shield to block the poison, it opened its mouth again and spat out a gold, red, and blue tricolor light ball.
This light ball combined the sharpness of the gold element, the explosiveness of the fire element, and the coldness of the ice element. The terrifying energy fluctuations were infinitely close to the level of a Four-Ring Soul Ancestor.
Furthermore, it was accompanied by the ice-fire poison, as well as the metallic poison influenced by the ice-fire poison.
With the three poisons combined and the terrifying energy gathering, the power of this strike was also not to be underestimated.
They were clearly just three two-ring Spirit Grandmasters and one one-ring Spirit Master, but the scale of this battle was already no less than a battle between several Four-Ring Soul Ancestors!
This was the true strength of the current Hongchen Siblings and the siblings Xu Tianhao and Xu Tianzhen!
Moreover, Xu Tianhao had not yet used his full strength; after all, he was a possessor of twin spirits.
However, for the sake of secrecy, The Hongchen Siblings did not yet know that Xu Tianhao had twin spirits.
"Whoosh—!"
The Huang Long Ray sped forward and directly collided with the huge light ball.
Under the collision of the two terrifying forces, a violent explosion was produced, stirring up a huge wave of air.
The ice-fire poisonous gas diffused directly in the explosion, but it had no effect on The Hongchen Siblings.
Xu Tianhao and Xu Tianzhen relied on their remaining spirit power to painstakingly maintain the glazed shield, preventing the poison from entering their bodies.
The giant toad, Xu Tianzhen, and Xu Tianhao were all shaken back several meters. Because they didn't have enough spirit power, their martial soul avatars were directly deactivated.
The spirit power of both sides was basically exhausted, making it difficult to launch any subsequent attacks.
After a long while, Kong Deming clapped from the side, his face full of a proud smile.
"Not bad! Children, you are all geniuses, the future of the Empire." Kong Deming praised sincerely:
"To have such strength at such a young age, I can't imagine how many surprises you will bring me once you grow up in the future!"
Although his personal disciple was only Xu Tianhao, over the past six months or so, he had also raised Xu Tianzhen and The Hongchen Siblings as if they were his own children.
Watching them grow and improve, Kong Deming was sincerely happy in his heart.
Kong Deming raised his hand to disperse the remaining poisonous gas and used his spirit power to restore the spirit power of The Four Little Ones and nourish their bodies.
Kong Deming smiled and said: "This battle is counted as a draw. I look forward to your future growth."
The four of them retracted their martial souls, accepted Kong Deming's spirit power nourishment, and each showed a smile.
