Udi did not answer the Necromancer Master, his dragon eyes slightly turned, scrutinizing his surroundings.

With his magical mastery, he could barely discern that there were some spells with a significant ring number in this cave.

Teleportation, attack... and some kind of special spell with extremely intricate patterns.

"The complexity of these spell patterns far exceeds the Eighth Ring Spell I’ve learned. Ninth Ring? No, the patterns of a Ninth Ring Spell could not be this much more complex than an Eighth Ring... Could this be a Tenth Ring Spell?" Udi was startled in his heart, but his face remained expressionless.

The Necromancer Master’s cold gaze had been fixed on the Black Dragon Lord. Seeing that he seemed unaware of his own manipulations, he felt slightly relieved.

The strength exhibited by the Black Dragon Lord now would have been negligible if he were at his peak, but currently, his foundation was damaged. His tier was only at the Tier One Peak; having a conflict now... even with various means and trump cards, he would not be afraid, but it would certainly be troublesome.

At this moment, a large number of cracks in the defensive shield on the altar had been restored to their undamaged state with the influx of massive energy.

The Necromancer Master felt assured and said to the Black Dragon Lord,

"Black Dragon, although we’ve had some misunderstandings before, it’s nothing more than a remnant Legendary Soul.... How about this, I’ll give you one hundred thousand Low-Level Souls, we sign a contract, and that matter is resolved, while you also keep this altar’s situation confidential, how does that sound?"

"One hundred thousand Low-Level Souls? Too few. This is a battlefield of over eighty million lives. By the end of a war, at least several hundred million lives die... at least one million Low-Level Souls." Udi shook his head slightly, his expression indifferent.

When he failed to break through the altar’s protective shield and crush the Necromancer Master during the surprise attack earlier, the opportunity to kill the opponent was lost.

Who knows how many teleportation and life-saving spells this Necromancer Master had prepared?

Although Udi had learned an Eighth Ring Anti-Magic Field Skill, which could suppress magic within a certain range, in the end, it was still just an Eighth Ring Spell—neither invincible nor unsolvable. Facing a Legendary Grand Mage, one must maintain a certain degree of reverence.

To advance as a caster to the Legendary level, one requirement is to master a large number of Returning to Truth level spells of various rings, including many Seventh Ring, Eighth Ring, and even Ninth Ring Spells.

And all are at the Returning to Truth level!

Udi had learned three Eighth Ring Spells, all at entry level.

The Necromancer Master, seeing that the Black Dragon Lord had the intention to negotiate, felt slightly relieved in his heart, but when he heard the other’s greedy demand, his eyes widened immediately as he shook his head,

"Impossible! One million Low-Level Souls, I might not even gather that much by the end of this war. You should be aware that the souls of beings who believe in the Divine Spirits are led to the Divine Kingdom after death, and I can’t compete with Divine Spirits for souls!... At most two hundred thousand souls, that’s my limit, otherwise, we might as well have a fight!" the Necromancer Master said in a deep voice, his tone quite dissatisfied.

Udi narrowed his dragon eyes, staring at the Necromancer Master for a long time, until the latter was extremely alert, before withdrawing his gaze and grinning,

"Two hundred thousand it is."

"Then let’s sign the contract." The Necromancer Master’s tone softened, his expression indifferent.

"So which Divine Spirit are you planning to use as the contract arbiter?" Udi inquired curiously.

Being detested by almost all the Divine Spirits, naturally, it was impossible for the Necromancer Master to use one of those who despise necromancers as the arbiter... it was like having a thief guard your house.

The Necromancer Master let out a cold snort, obviously recalling those hated Divine Spirits, and blandly said, "Let the God of Contract be the arbiter."

The God of Contract? Udi nodded slightly.

As a Divine Spirit who ascended by the authority of contracts, regardless of whether beings are evil or good, they could seek him as an arbiter.

Even the Evil Gods sometimes sought this God of Contract for arbitration.

Because a Divine Spirit’s divine side cannot deviate from the scope of their authority, this is a rule.

Then, under the witness of the God of Contract’s divine side, the two parties signed the contract.

The contract was simple: Udi could not expose nor interfere with what the Necromancer Master was doing beneath the battlefield.

Once the contract was completed, the Necromancer Master reluctantly threw a transparent crystal bottle to the Black Dragon Lord and coldly said,

"Inside are two hundred thousand Low-Level Souls, Black Dragon, now you can leave."

Udi extended his dragon claw to catch the transparent crystal bottle. By the naked eye, it was completely undetectable that the crystal bottle contained two hundred thousand souls.

Without reaching a Legendary level, the souls are invisible to the naked eye and require special Spiritual Vision to be seen.

A Spiritual Light covered Udi’s dragon eyes, as he looked at the crystal bottle.

Now he could see the densely packed gray-white soul gas floating inside the crystal bottle.

Each strand of gray-white soul represented a life that had reached a Low-Level tier before death.

Sweeping the crystal bottle with his powerful Spiritual Power, Udi nodded slightly, it was indeed two hundred thousand Low-Level Souls.

Though the contract had been set, making it unlikely for the Necromancer Master to play tricks, personally verifying it was still reassuring.

"Farewell."

Benefiting from the situation, Udi was exceptionally straightforward, and with his dragon claw dragging a Void Descendant, he passed through Any Gate and vanished from the underground cave.

The underground cave became quiet once again.

The Necromancer Master’s expression turned somber, his pupils flickering with green light,
