"When dealing with monks who burrow into the ground, you can kill them with piercing spells before they even burrow into the depths of the earth. As for the attacks from the monks in the reclusion, as long as they are out of the range of those monks' attacks, they are not easy to attack. And the actions under the surface of the earth will consume a lot of spiritual power, and there is no way to absorb the free spiritual energy between heaven and earth, all they can rely on is to restore spiritual power in the elixir. Therefore, in a place like ours, where the land is sparsely populated and there are many large rocks under the surface, it is very thankless for monks who are good at drilling into the ground. Even if there are many monks who practice the spell of retreat, it is only to dodge attacks from flying spirit beasts, or to use retreat methods to dodge attacks in times of danger. ”

After listening to Dai Shu's explanation, Zuo Zhe also realized the problem of retreat spells. In positional warfare or siege warfare, reluctance spells can also come in handy. But if you are fighting in the field, you have given up your speed, and you are just using the ground to avoid attacks. However, Zuo Zhe always felt that fighting in the middle of the world was also a very strong way of fighting. The reason why the earth's armed forces are divided into army, navy, air force and space force is because they have the combat capability of the four battlefields of land, sea, air and space. And if the earth's army also masters weapons and vehicles that can quickly drill into the ground, it is entirely possible that there will be a "ground army" and other military branches on the earth.

For the attack from under the surface, the protective array of the Sifang City has also begun to operate, constantly condensing powerful earth-based spells under the land outside the city wall, blocking and killing those spirit beasts that burrow into the ground.

However, it was not enough to rely solely on the Quadrangular City's protective array. At this time, monks who can use the earth-burrowing spell are needed to fight the spirit beasts beneath the surface. However, even if Zuo Zhe did not give up the oath of allegiance of the eight thousand monks, Zuo Zhe would not order these guild monks to go to battle. Rather than forcibly forcing monks to be cannon fodder, Zuo Zhe prefers a carrot in one hand and a stick in the other.

The so-called carrot is the task reward that Zuo Zhe is about to take, and the big stick in Zuo Zhe's hand is the threat of expulsion from the guild. At the same time, Zuo Zhe will also follow the methods on the latest issue of "Otherworldly Raiders" formulated by the logistics department of the Dragon Guild to secretly spread the news that those who are expelled from the guild will be used as cannon fodder, and that the guild will soon sell spell cheats.

In this way, through overt and covert operations, Zuo Zhe gradually strengthened the binding force of the Dragon Guild on its members. However, the Spirit Power Continent is a world with extremely high individual force value after all. If he wanted to get the monk to submit, Zuo Zhe could only do so by strengthening his personal force. However, fortunately, although Zuo Zhe only has the extraordinary strength of the Heavenly and Human Realm, he can use the ability of the domain at a critical moment, but the monks of the Sifang City dare not underestimate Zuo Zhe.

Under Zuo Zhe's prompting, Dai Shu, who was in charge of the government affairs of Sifang City, immediately led people to Sifang City to issue a task in a loud voice. Yes, at night, the way the Dragon Guild issues quests is through the monks shouting everywhere. Originally, Zuo Zhe also wanted to take out some horns. However, such thoughts were still suppressed by themselves. It's not that the number of speakers is insufficient, nor is it a problem with the power supply of the horns, but Zuo Zhe found that the volume of ordinary speakers is far less loud than the shouting of monks who open their throats! In the Spiritual Power Continent, some monks specialize in cultivating sonic attacks! Not to mention the sound that can be heard by the human ear, even if it is ultrasound and infrasound waves that cannot be heard by the human ear, these monks can shout it!

Although it was late at night, no one slept in the Sifang City tonight. In fact, the 180,000 monks in the city, except for those who were responsible for defending the walls and patrolling the streets, remained in their respective residences in a state of restlessness. Just tonight, more than 20 monks who went out to go to the toilet were killed by the patrolling monks! No matter what the monks who went to the toilet explained, if they dared to leave their respective residences for no reason, they would be killed mercilessly! In this regard, the residents of Sifang City knew about this rule. In previous years, there were always some gangsters who took advantage of the beast tide in Sifang City to go out and rob the house. Therefore, whenever the beast tide comes, the city of Sifang City will be under martial law, and everything that is harmful to Sifang City is strictly prohibited.

As the task of recruiting Drill Monks with Spell Cheats was issued, clusters of torches immediately appeared at the doors of many rooms in the city. Attracted by the torches in the houses, the monks patrolling the neighborhood immediately went to investigate, and brought the monks with the torches in front of the gate to the city walls of the four square cities. Yes, light the torches in front of the door, this is the sign of accepting the task. In the face of great benefits, the number of monks who are willing to take risks is not small. What's more, the monks who participate in the offensive and defensive battles of the beast tide will have the right to select the corpses of spirit beasts after the beast tide. And if the monks in the Sifang City don't come out to help defend the city, once the Sifang City is breached by the beast tide, the monks of the big forces and big families can still rely on the magic array to forcibly break through and escape, but the small forces and the civilian monks have only one way to die! At that time, even if the civilian monks burrow into the ground, they will be chased and eaten by the spirit beasts!

In just ten minutes, thousands of monks who were good at drilling into the ground had accepted the task and were taken to the vicinity of the city wall by the patrolling monks in batches. After receiving the spell cheats promised by Zuo Zhe, these monks deposited the first half of the spell cheats in the storage boxes with their own marks and suicide notes on the inside of the city wall. In case they hang up, the first half of the spell cheats in the storage box will be obtained by their respective families, so that their children can obtain better cultivation conditions and improve their cultivation and strength faster.

If the rewards were only money or guild points, these monks would not be so enthusiastic and fearless of death. However, the task reward was a spell cheat that they had been searching for but could never obtain! It was precisely these spell cheats that were originally held in the hands of the wealthy clans that made almost all the monks in the Sifang City join the Dragon Guild without hesitation! And now, Zuo Zhe actually gave such a rich reward! If it weren't for the fact that most of the monks were not good at underground battles, the number of monks who came to accept the task would definitely be more than five times great! And now, most of the monks staying in their respective homes are working hard to cultivate earth-based spells, and some are still making one-time earth-based spell-casting items, trying to obtain certain underground combat abilities by sharpening their knives in battle!

Watching these monks leap out from the high city and urge the earth-based spells to quickly escape into the soil, Zuo Zhe slapped his thigh fiercely, and finally realized his mistake. After seeing these thousands of monks burrowing into the soil with a large number of elixirs and earth-based spell props, Zuo Zhe finally thought of a weapon that could be used in underground battles! That kind of weapon was a ground-penetrating missile and a mine! It's a pity that Zuo Zhe didn't prepare before, and the earth didn't expect this kind of combat to exist in the offensive and defensive battles of Sifang City, so he didn't prepare in advance.
