In the following time, Song Zhong devoted himself to large-scale production. Under his urging, the construction of the city wall and the production of dragon-marked cannons progressed extremely quickly.
Due to the pressure from the demon clan, the craftsmen worked hard and did not dare to slack off in the slightest. Song Zhong estimated that as long as he was given a month, the city wall could be built over a hundred feet high, and there would be 100,000 dragon-patterned cannons. If the monsters come to attack then, he will pile the newly produced dragon-patterned cannons on the top of the city and fight these guys to the death.
In this tense period, Song Zhong did not dare to be careless in the slightest. He ordered the dispatch of scouts to patrol the sea intensively every day. He constantly monitors the sea area within a hundred thousand miles, for fear of being raided again.
If within a month, that is, when primary defense is not carried out, it is attacked by the demon clan, then Song Zhong's Chentang Pass will probably be in danger. So this month is the most critical.
But fortunately, according to the information obtained from the old man here, the demon clan's troops are not just available. In the last attack, the opponent suffered extremely heavy losses. Even if they wanted to retaliate, they could only mobilize friendly forces from other sea areas. In that case, it will take a month or two at least to talk.
Of course, once the other party plans to retaliate and is fully prepared, their size and strength will be greatly increased. Therefore, the situation Song Zhong faced was that he would either not encounter a battle, or if he did, it would definitely be an extremely brutal battle.
It was precisely because of this that the injured Song Zhong did not recover properly and stayed outside all day, carefully calculating various countermeasures to deal with the enemy.
…
Just when Song Zhong was making deliberate efforts to resist the demon army. Zhu Rongtian's Huode Xingjun received an extremely strange report from his subordinate officials.
"Lord Qi, I have investigated everything clearly. None of the true monarchs in Zhu Rongtian have sold to Song Zhong Tiemu!" The official said with a serious face: "Not only that, the subordinates I have strictly inspected various trading markets, and I have not seen anyone buying Iron Mother privately."
"What?" After hearing the news, Lord Huodexing was immediately surprised and said, "Are you sure you're not mistaken?"
"There is absolutely no mistake!" The subordinate officer said with a grimace: "Zhu Rongtian's output is limited. My subordinates investigated and compared one by one and found that our output has increased in recent months, but the increase All the parts have been turned into weapons and armor, and everything is in the warehouse. There is absolutely no mistake! They may be able to hide a little bit of their output, but the iron mother who built the Great Wall cannot be hidden even by gods? "
"That's strange. Where did the Iron Mother in Song Zhong's hand come from?" Huode Xingjun suddenly said: "Ah, by the way, could it be that Zhu Rongtian's demon clan sold it to him privately?"
"My subordinates have thought of this a long time ago. So I specially investigated the Demon Clan privately. It seems that they did not secretly sell Iron Mother to Song Zhong!" the subordinate officer said helplessly.
"Perhaps they are doing it in secret, and you obviously don't have the ability to find out the internal information of the demon clan!" Lord Huode Xing frowned.
When the subordinate officer heard this, he immediately smiled bitterly and said: "Sir, maybe the demon clan's intelligence is not available to my subordinates, but even with speculation, we can know that it was not them! With such a large number of iron mothers, we can use tens of thousands of feet to get it. Blast furnace production requires a lot of effort, and it is even more laborious for the demon tribe to refine it using primitive methods. If they have to spend so much effort to smuggle iron mother, anything else they can get will be better than this low-grade material. How about earning tens or even hundreds of times? Unless the top leaders of the Demon Clan are mentally ill, they wouldn't do such a stupid thing?"
"Ah, this~" Huo Dexingjun frowned and said: "It seems to be the same! From their perspective, they shouldn't look at such low-level materials. But if it weren't for them, where would Song Zhong's iron mother come from? ? You can’t just conjure it up yourself, right?”
"Sir, do you think it was produced by Song Zhong's Donghuang Realm? I have heard that several True Lords who are closely related to Song Zhong have bought enough high-end materials from him to complete the project. Heavenly Court’s mission, for which I earned a lot of contribution points!” said the subordinate officer.
"I've heard about this too, but the problem is, you also know that Song Zhong's Donghuang Realm is full of garbage. Even if there is a mine, excavation requires manpower. Only a few hundred of Song Zhong's men can survive. Wan's flower demon has to build his lair and dig out high-grade materials, so where can he spare his hands to get the iron mother that can build the Great Wall?"
"Well, maybe he has other ways!" the officer said reservedly, "Well, otherwise, I will go to Donghuang Realm privately to investigate, as long as it is not exposed!"
Lord Huodexing heard this and immediately said: "No, it is a serious crime to break into someone else's territory privately. If you are discovered, even I can't save you!"
"But~" the subordinate officer frowned and said, "If we don't investigate the origin of the iron mother in Song Zhong's hands, I'm afraid there will be a lot of gossip and controversy? Others will say that you are partial!"
"I know!" Lord Huo Dexing frowned and said, "How about this? I'm sending you on a business trip to the Eastern Emperor Realm to discuss the acquisition of high-end materials. During the negotiations, you have a lot of eyes and take the opportunity to find out what's going on. What's going on? Do you understand?"
"Yes, I understand!" the subordinate officer quickly agreed.
"As long as you understand, go ahead and come back quickly!" Lord Huo Dexing warned.
"Yes, I am resigning!" The subordinate officer agreed, then bowed and exited.
…
While Lord Huo Dexing was secretly investigating Song Zhong, Song Zhong was also suffering for a month. After all, the demon army did not attack Song Zhong when he was most vulnerable, which made Song Zhong somewhat relieved.
With this month's buffer, Wanli City Defense has begun to take shape. The highest point is more than 150 feet, and the worst point is also 120 feet. Although it is still far from Song Zhong's requirements, it can already have a certain degree of defense. .
So Song Zhong ordered the pouring to be temporarily stopped and began to carve out defensive formations and various restrictions. A city defense without these things would be completely useless under the attack of the demon clan. Once the protection is in place, it will become a copper wall and an iron wall, causing the invading demon clan to smash their heads and bleed with blood.
Drawing the formation is actually a relatively troublesome job, but fortunately there are many people in Song Zhong, millions of monks go into battle together, working day and night, taking turns. The speed increased quickly, and in just six or seven days, the outer restrictions were almost completed.
And this also cost Song Zhong a huge amount of inventory. Not only did Chen Tangguan use up almost all the relevant materials, but Song Zhong also used up 7,788 of the materials decomposed in his own natal space.
Fortunately, with the initial protection, it can generally resist the attack of the demon clan, so Song Zhong is not in a hurry to get those high-end materials. Just let them continue to build the city wall. When the city wall is completed, hey, the materials in Song Zhong's natal space will have almost decomposed into a new batch.
However, Song Zhong's good mood did not last long before he was broken by the scouts in front. As expected, the Sihai Monster Clan will not suffer easily. After such a long period of preparation, their revenge has finally begun!
The first unlucky thing was the reconnaissance force sent by Song Zhong. Less than half of the small group of thousands of scouts came back alive, and the news they brought cast a shadow over the entire Chentang Pass.
Judging from the flags, there are actually seven big demons in the demon army coming this time! That is, seven Daluo Jinxian level monsters are here to avenge the two dead companions.
The men of these seven great demons rushed towards them along the sea, covering thousands of miles horizontally. It was impossible to tell how far they were vertically. In short, they were vast, boundless, and countless. The most preliminary estimate is that the number of troops is more than 30 million!
Such a perverted army could not even defeat Chen Tangguan in his heyday! Not to mention that now, Commander-in-Chief Song Zhong and Deputy Commander-in-Chief Tian Xuejian are unable to take action due to injuries. With all their plans, the only person who can compete with the big demon is Huang Jixiang.
The city defense of Chentangguan is not outstanding either. Although once completed, the thousand-foot city wall and countless dragon-patterned cannons can form an invincible fortress. But now, with only a city wall over a hundred feet high and a hastily drawn protective formation, it is far from being called invincible!
After getting the news, Song Zhong immediately called a meeting. Huang Jixiang, Feng Xi and more than a hundred golden immortals came to the meeting.
When everyone heard that they were facing this situation, everyone, including Huang Jixiang, couldn't help being shocked and turned pale with fear.
Huang Jixiang directly said with a grimace: "Boss, the enemy is too strong, we can't resist it! Should we retreat quickly?"
"You want me to run away from the battlefield?" Song Zhong glanced at Huang Jixiang lightly.
"It's not an escape, it's a strategic shift!" Huang Jixiang said hurriedly: "Let's retreat to the big city behind and continue to block them. It's the same!"
"It's different!" The person who spoke this time was Feng Xi, who said with a grimace: "If we retreat, Chentang Pass will be finished. This place is a strategic location, supported by more than a dozen dragon veins behind it. The immortal energy is extremely rich. It is precisely because of this that we want to occupy this place. And if it falls into the hands of the demon clan and wants to take it back, it will be harder than climbing to the sky!"
"But if we don't retreat, we will die!" Huang Jixiang said angrily.
"If you withdraw, you will die!" Feng Xi said with a bitter face: "Heaven's laws are not strict. Those who flee before fighting will have only one fate, they will be killed without mercy!"
