The second base built by the Outer Realm Cultivators had yet to take shape. Its energy shield was only a thin layer, and such a defense was nearly useless underground. If Feng Ying and the others could somehow dig a tunnel beneath the base, then plant a mountain of Explosive Jade Talismans, Black Spiders, and other explosive devices below it, the powerful blast would form terrifying black holes. Destroying the base in one fell swoop would be no difficult feat.
If they were lucky, they might even destroy all the large Universe Flying Saucers inside the base. There were over a thousand of them. If they could wipe them all out, the Outer Realm Cultivators would need tens of thousands of years to recover, and the pressure on the God Realm would naturally ease considerably.
If they could buy tens of thousands of years, perhaps by then Ling Tian and the others would have already returned from the Beast Soul Realm with the Phoenix Soul Fruit. Then they would no longer need to worry about the Outer Realm Cultivators attacking Beast Soul Valley, and Feng Ying and the others would be free to contend with them properly. With enough time, defeating or even wiping them out would be entirely possible.
Even if the explosion failed to destroy all the Outer Realm Cultivators' large Universe Flying Saucers, it could still throw their formation into disarray. Feng Lingzi and the others could then launch a surprise attack amid the chaos and surely reap a fine reward.
Soul Severing Cliff had high-ranked Ancient Divine Beasts skilled at digging tunnels, such as the Golden Pangolin and the Gold-Swallowing Demonic Rat. Having them carry out this mission wouldn't be too difficult.
Of course, digging would make some noise, so Feng Lingzi and the others would
