Everyone accepted the order and, with Venti's help, flew into the air using the wind, concentrating their attacks on the poisonous blood on Dvalin's body.
Dvalin's dragon claws struck again, and this time Jean blocked the attack.
Jean thrust out the Windblume Ode in her hand, and the Anemo element rotated and compressed, concentrating at the tip of the sword.
It was precisely Jean's 'Gale Blade'.
Dvalin's power was extraordinary, but fortunately, Jean was not an ordinary person either.
Not only did she block Dvalin's attack, but she even caused Dvalin to experience a brief stun.
Several Anemo arrows flew out, swirling, flying in an incredible trajectory like homing arrows.
They finally shot into the poisonous blood on Dvalin's back.
"Roar!" Dvalin let out a cry of pain, spitting out dragon breath and attacking Venti.
"Whoosh~" A wind current suddenly appeared under Venti's feet, blowing him high into the sky, allowing him to dodge the blow.
Dvalin wanted to pursue, but a huge firebird flew over, its surging Pyro elemental power forcing him to pay attention.
Dvalin's claws grabbed the firebird, directly tearing apart the firebird made of Pyro elements.
Tearing apart the firebird was not enough; Dvalin let out a long roar, and instantly, gusts of strong wind swept across the field.
As long as everyone stayed in place for a period of time, wind vortices would generate from beneath their feet, then stir up strong winds.
This forced everyone to constantly be on the move.
"This won't do; we can't compete with a dragon in terms of stamina," Diluc said.
Jean nodded, then seemed to think of something, looking left and right but not finding the Traveler.
"Where's the Traveler?" Jean asked.
At her question, Diluc also realized that the Traveler seemed to have been silent since the battle began, and he didn't know where she had gone.
"Hehe." Venti smiled, pointing a hand at Dvalin.
It turned out that Lumine had already run onto Dvalin's back at some unknown point.
The maddened Dvalin seemed to not have noticed anything unusual.
He still focused his attention on Venti and the others, who posed a greater threat.
Lumine also seemed afraid of being discovered and having her efforts go to waste, so she was not making any moves at the moment.
"Cooperate with her!" Diluc immediately made a judgment.
His dodging footsteps stopped, and he took a step forward, charging towards Dvalin.
"Yes, Senior." Jean also immediately made a judgment.
She charged towards Dvalin from another direction.
The two of them, one on the left and one on the right, closed the distance with Dvalin.
This caused Dvalin to constantly look left and right, immediately diverting his attention from his back.
Lumine seized this opportunity to quickly approach the poisonous blood, closing the distance between herself and the poisonous blood.
What about Venti?
Venti had already put away his longbow, instead playing a piece of music for everyone on his wooden lyre.
The music itself had no power, but under the Anemo Archon's performance, it became a buff.
It could enhance everyone's affinity with the Anemo element.
"Gale Blade!"
Jean leaped with the help of the wind current, appearing in front of Dvalin, thrusting her longsword towards Dvalin's vulnerable eyes.
Dvalin raised his claw and swatted at Jean; although this blocked Jean's attack, it still caused a stun effect.
Lumine took advantage of this moment to climb near the poisonous blood, raising the dawn sword in her hand.
"Yaaah!" Lumine stabbed down with force, Anemo elemental power frantically condensing on the longsword.
"Roar~" Dvalin cried out in pain.
However, the force of this blow was not enough; it seemed unable to sever the poisonous blood.
"Dawn!"
Diluc's slash came at the right time; this blow landed on the poisonous blood, making it a bit more fragile.
A shattering sound rang out, and Lumine successfully severed the poisonous blood.
However, there was still one more spot of poisonous blood on Dvalin's body.
But the disappearance of one spot of poisonous blood still allowed Dvalin to briefly regain some sanity.
"Barbatos..."
Dvalin's gaze, no longer obscured by madness, looked at Venti.
"Why do you want to save me?"
"Mondstadt no longer needs the East Wind Guardian..."
Venti did not stop playing, his tone gentle, speaking as if singing a poem.
"Dvalin, if you were me, and had seen your lonely figure soaring in the sky, you too would fight for this beautiful sight."
"Today's sky has no snow or wind, the earth is full of greenery; Mondstadt needs neither a guardian nor an Anemo Archon."
"Just like before the era of the Four Winds, I walked the earth, singing of the wind, and you flew high in the sky, overlooking the land."
"This is freedom."
Not only did Dvalin take these words to heart, but even Diluc's perception of Venti changed further.
Before, although he thought the Anemo Archon was somewhat reliable, he had no actual feeling for it.
After all, the Anemo Archon he encountered drank alcohol every day.
Now, he finally understood why the other party was the Anemo Archon and why he could lead Mondstadt on the path of freedom.
Jean's emotions were even deeper; no wonder so many people in Old Mondstadt joined the Anemo Archon to overthrow the tyrant.
How could such a god not make people want to follow him?
"freedom?"
Even Lumine seemed to have a deeper understanding of the freedom that the Anemo Archon pursued.
"Is that so... Barbatos, if you were me..."
Dvalin's words were cut short as his eyes were once again consumed by madness.
Everyone prepared for battle again.
"The previous tactic, again?" Lumine tentatively asked.
Before Diluc could speak, Jean shook her head.
"No, the risk of doing it again is too great."
If the Traveler hadn't started acting without a word just now, Jean wouldn't have agreed to the first plan either.
"Then it seems we can only go in hard." Lumine shrugged.
"This time, let me do it." Venti suddenly spoke.
At this moment, the ends of his braided hair began to glow.
Now that one spot of poisonous blood had been removed, Dvalin's corrosion and hostility had weakened considerably.
"I also really want to know what Dvalin wants to say."
After Venti finished speaking, his figure floated lightly, flying all the way in front of Dvalin.
A giant dragon and a young man; the young man's height was not even as tall as one of the giant dragon's claws, yet the young man showed no fear.
Venti slowly placed his hand on Dvalin's head, his tone gentle.
"Dvalin, I have returned."
As soon as his voice fell, a terrifying Anemo elemental power erupted, as if a wind barrier enveloped the two of them.
The soft barrier turned the entire space azure.
Gentle winds continuously blew over everyone, making them very comfortable.
All the strong winds summoned by Dvalin vanished without a trace, leaving only gentle winds within the space.
The gentle wind calmed Dvalin's emotions, causing Dvalin's hostility to weaken further.
Removing the second spot of poisonous blood was only a matter of time.
As long as the poisonous blood was removed, Dvalin's sanity could be restored.
"This is the power of Barbatos..."
Jean exclaimed, momentarily forgetting to call him Venti and directly calling out the Anemo Archon's name.
"Astonishing."
Diluc remained expressionless.
However, he had already put away his greatsword, crossed his arms, and began to observe, clearly trusting Venti greatly.
"Is this a god?"
Lumine recalled the god who had stopped her and her brother back then; that god's power was not as gentle as the Anemo Archon's.
"Woah, woah, woah, the bard is that powerful?" Paimon was a little scared.
She always called him the bard; he wouldn't get angry, would he?
He probably wouldn't; Venti was quite good-tempered with his own people.
Moreover, he preferred it when others interacted with him without caring about his identity.
