122: Siege weapons, but can only be admired with a sigh.

For example, the [Starfall City-Breaking Crossbow] had a body made of thousand-year sunken wood and limbs forged from extra-terrestrial refined gold. Its string, twisted from ten flood dragon tendons, shimmered with a dark gold luster. The arrow slot required special arrowheads cast from starfall iron cores, and firing it required thirty Core Formation Cultivators to simultaneously inject spiritual power.

It specialized in attacking large-scale defensive works such as the enemy's mountain protection Formations and war walls.

Once fired, the arrow could harness the spiritual energy of heaven and earth, transforming into a fire meteor a hundred zhang in diameter as it crashed down.

It could not only tear through Formation shields but also trigger a wide-range explosion of spiritual fire, dealing dual damage of burning and shock to the Cultivators within the fortifications.

Another example was the [Black Armor Flying Boat Mothership], a thousand-zhang-long giant Flying Boat that resembled a mobile fortress. Its hull was covered in thick black tortoise shell plates, and its surface was engraved with runes of the 'Tiangang Defense Formation'.

Not only could it house a hundred small combat Flying Boats and a thousand Cultivators, but its deck was also equipped with ten Spirit Energy Cannons.

Each Spirit Energy Cannon required ten Core Formation Cultivators to operate. After being infused with mana of the same attribute, they could fire mana shells comparable to Formation-level attacks.

Even more impressively, the Flying Boat itself possessed the ability of invisibility, allowing it to evade enemy detection for short periods.

The shield formed by the Tiangang Defense Formation also came with a reflection effect; however, due to the National War rules, it could only reflect Spell attacks from Cultivators below the Peak Core Formation Stage.

Its flight speed was also comparable to a High Grade flying Magic Treasure.

There were many such battlefield weapons on the light screen, making Su Ling's heart burn with desire.

But he quickly calmed down.

These war Magic Treasures required at least a hundred thousand or even a million merit points to exchange.

Furthermore, they had to be handed over and recycled after the National War ended.

With Spirit Stones alone, one didn't even have the qualification to purchase them.

More importantly, these large-scale Magic Treasures required the cooperation of many people to operate, making them completely unsuitable for a Cultivator like him who was used to acting alone.

Suppressing his envy, Su Ling slowly moved his gaze away, finally landing on the Magic Treasure and Medicinal Pill categories on the light screen.

These were what suited him best at the moment.

"I see that Fellow Daoist has a faint rhyme of thunder flowing around you; it seems your thunder arts have reached a considerable Realm."

Seeing Su Ling's gaze lingering on the light screen as if hesitating, the Nascent Soul Steward smiled slightly and took the initiative to guide him. "This Thunder Tempering Pill can purify thunder-attribute mana and also has a Body Tempering effect. For a thunder Cultivator like Fellow Daoist, it couldn't be more suitable..."

"What Senior says is exactly what I have in mind."

Su Ling pondered for a moment, then cupped his hands and asked, "However, there is one thing I am still unclear about... will the efficacy of this Thunder Tempering Pill decrease with the number of times it is consumed?"

"This old man's name is Wei Yang. Fellow Daoist can just call me by my name; there's no need to call me Senior."

Wei Yang stroked his long beard, his fingertip lightly touching the light screen to enlarge the details of the Thunder Tempering Pill. "You can rest assured about the quality of the pills from our Bitao Sect Alchemy Hall. The efficacy of the first three Thunder Tempering Pills will not decrease at all. From the fourth one onwards, the efficacy is halved. If you consume more than five, the cost-effectiveness becomes too low, and it would be better to exchange for other auxiliary pills instead."

"In that case, I'll exchange for five Thunder Tempering Pills first."

Su Ling understood and nodded in agreement.

One Thunder Tempering Pill was worth five hundred thousand Low-Grade Spirit Stones. To him, who now held fifty million Spirit Stones, it was just a drop in the bucket.

Yet it could truly improve the purity of his thunder arts, making it a worthwhile deal.

"However, since Fellow Daoist specializes in thunder arts, why not take a look at this 'Thunder-Patterned Heart-Protecting Mirror'?"

Wei Yang changed the subject, tapping his finger on the light screen and sending a streak of spiritual light into the Magic Treasure area.

A projection of a treasure mirror covered in azure-gold thunder patterns instantly appeared.

"This mirror can harness one's own thunder power to form a shield, capable of blocking thirty percent of a Nascent Soul Cultivator's attack. In terms of practicality, it's even better than simple pills."

"It's worth two million Low-Grade Spirit Stones."

Thunder patterns flowed over the mirror's projection, and its spiritual light was lustrous; it indeed looked extraordinary.

Su Ling focused his gaze to observe it closely, but a projection was just a projection, and his Immortal Eye of Treasure Appraisal could not probe the mysteries within.

"I wonder if I might be allowed to see the physical object?" Su Ling asked.

"Of course."

Wei Yang nodded. With a thought, the previously smooth wall behind him suddenly split open, revealing a three-foot-wide opening.

Spiritual light flickered inside the opening; it was clearly a restricted space specifically for storing Magic Treasures.

A jade box flew out from the opening and landed steadily on the low table between them. Wei Yang raised his hand to unlock the box, revealing the Thunder-Patterned Heart-Protecting Mirror.

The mirror's body was azure-gold, with a ring of spiritual jade embedded around the edge.

It felt slightly cool to the touch, and the thick thunder power contained within could be clearly felt.

[Thunder-Patterned Heart-Protecting Mirror, a High Grade defensive Magic Treasure forged from Thunder-Patterned Refined Gold and Huan Spirit Jade. It can harness thunder to form a shield and has a significant defensive effect against Spell attacks.]

Su Ling condensed a wisp of Azure Firmament Mana at his fingertip and slowly injected it into the mirror.

With a soft "buzz," a translucent azure thunder shield instantly unfolded around him.

Thunder patterns moved across the surface of the thunder shield, radiating a stable defensive aura.

He silently sensed the strength of the thunder shield, but his brow twitched slightly.

This defensive power was only on par with the coiling dragon shield formed by his gilded coiling dragon bell.

But the coiling dragon bell's nine flood dragon phantoms could also actively devour a portion of the attack energy to feed back into itself.

When he had purchased the coiling dragon bell at auction, it had only cost a little over two million Spirit Stones.

Calculating it this way, the cost-effectiveness of the Thunder-Patterned Heart-Protecting Mirror was indeed somewhat poor.

"Thank you for bringing out the physical object, Fellow Daoist, but this Magic Treasure is not quite suitable for me."

Su Ling placed the heart-protecting mirror back into the jade box and gently pushed it back in front of Wei Yang.

Even though he hadn't made the sale, Wei Yang didn't mind at all. Instead, he smiled and waved his hand. "No matter. There are still many treasures on the exchange catalog. Take your time, Fellow Daoist; there's no need to rush your decision."

Su Ling nodded and returned his gaze to the light screen, silently calculating in his heart.

Although he had seized many Magic Treasures over the past six months, few were actually suitable for him.

The thunder fang shadow splitting sword was currently his main weapon; unless he encountered a thunder-attribute supreme grade Flying Sword, there was no need to replace it in the short term.

The defense of the gilded coiling dragon bell was sufficient for now, and he hadn't seen any better supreme grade defensive Magic Treasures on the catalog.

As for the vajra jade washing robe and thousand-mile cloud-chasing boots, they were only Medium Grade Magic Treasures. If there were suitable High Grade magic robes or boots, they could be replaced.

And that scarlet gold bow was only a Low Grade Magic Treasure; he usually only used it to fire Ghost Soul Arrows, so it didn't even count as a support item.

Unfortunately, he hadn't encountered any Cultivators who used bow-and-arrow type Magic Treasures, so he had nowhere to exchange it even if he wanted to.

After a search, supreme grade Magic Treasures were not in the exchange list at all.

Su Ling couldn't help but guess that the difficulty of refining supreme grade Magic Treasures might far exceed his imagination.

Over the past six months, the number of direct Disciples from the Seven Sects who had fallen by his hand was at least seven or eight, if not ten.

Yet he hadn't obtained a single supreme grade Magic Treasure.

Even Li Hanchuan's Black Gold Mountain-Shaking Staff was only a high-grade magic treasure.

It was likely that even for Nascent Soul Disciples of the Seven Sects, supreme grade Magic Treasures were few and far between, so they naturally wouldn't be put out for exchange.
