Luoyang East City Wall.

I thought that the anti-army would give face, and there was no action on the day of Wu Guogong's wedding, who knew that it was a cover.

Wu Xin naturally couldn't take it lightly, so he took more than a dozen monks such as the old man of the mountains and rivers and the old ancestor of the trap to the east city wall. The silver-armored Wuwei and others continued to train in the Wuguo Mansion.

At this time, Tang Guogong Li Yuan, the eldest grandson Shunyi, and four or five thousand martial arts people had already arrived, and there were about two hundred great cultivators, and the rest were all in the middle and late stages of qi refining.

This is the first time that Wu Xin has seen so many great monks gathered, and if a martial arts conference is held, the majestic momentum makes the air a little sluggish, the atmosphere is solemn and depressing, and it is difficult for ordinary people to approach.

The territory of the Great Sui Empire, the original Kyushu, forty-nine prefectures. After the implementation of the two-tier system of counties and counties, it was divided into 365 counties and more than 2,000 counties.

There are about 2,000 great monks in the whole world, and each of them can dominate one side and can be called the ancestor, so there is a saying that the ancestor of the god is refined.

On average, there is about one great monk in each county, which is quite a coincidence. Maybe it's the ethereal luck problem, but gathering the luck of a county can support a great monk.

Now the eastern capital of Luoyang has gathered about 500 great monks, that is, nearly a quarter of the world's great monks.

This is the Land of Storms.

Of course, except for the barbarians, the barbarians are basically in poor mountains and rivers or remote and barren places, and they are inaccessible. Most of the barbarian monks are not in the records of the Great Sui Empire, how many specifically, no one really knows, there are definitely not as many as the Great Sui Empire!

About 500 meters from the eastern city wall, there are soldiers and a simple wooden fence to guard it.

"Lord!"

"Left-behind adults!"

When Wu Xin arrived, the eldest grandson Shunyi, Li Yuan, and Cai Yan, the commander of the Fengjun army, greeted him.

Wu Xin frowned and nodded, and without caring about being polite, he observed the environment......

Every 500 meters, there is a flow of people, carrying earth and rocks and other things, looking at the past. The scene was fiery and noisy.

Countless soldiers are digging a deep ditch about 100 meters long, about 20 or 30 meters wide, and of unknown depth.

On the banks of the ravines, the land is swampy, firewood is piled up, thick smoke is billowing out, and some deep ravines are constantly being filled with soldiers entering and leaving, and the smell of blood is heard.

"How's it going?" Wu Xin looked at Cai Yan and asked.

Cai Yan consciously and quickly reported: "The rebel army dispatched the barbarian high priest to drive the earth-like beasts and the great monks, and dug countless tunnels, leading in all directions. Fortunately, General Li was on guard, and let people monitor the underground, and detect it in time, so he chose a place to dig a trench to intercept and investigate, only to find that the enemy army had dug countless tunnels. Now the two sides are fighting underground, and the situation is difficult to understand for the time being. General Lee is also ...... in the tunnel"

"Countless tunnels have been dug up, how deep is it?" Wu Xin asked with a frown.

The construction of a wall is not just a matter of piling stones on the ground. Similar to building a house, it needs to be built on a site, and it needs to be supported by the corresponding foundation. Otherwise, it is easy to collapse.

The eastern capital is more than 300 zhang high Tiandu-level city wall, and the foundation is at least 100 zhang. Further down there are layers of hard rock. The difficulty of digging tunnels is greater than digging rocks in the mountains.

But. Thinking about the strength of the Great Cultivator, Wu Xin was also relieved.

Don't talk about the great cultivators, as long as the Qi refining powerhouse holds the divine weapon. You can also dig through foundations and rock layers!

Cai Yan consciously responded: "The depth is about 100 zhang, and a total of 27 places have been dug, of which 24 have been dug into tunnels!"

"Twenty-four ......"

Wu Xin muttered with a heavy expression, he didn't expect there to be so many, so he looked at Li Yuan and Eldest Sun Shunyi and suggested: "Let's separate, send eight to ten great monk commanders in each place, and contact them at any time, how about it?"

"Yes!"

Although it was a suggestion, Wu Xin was left behind in the eastern capital, and it was not too out of line or mediocre decision, and everyone naturally would not refute or refuse.

......

A moment later, Wu Xin led the twelve great monks who had followed him into a large tunnel in the middle.

The entrance to this tunnel, vertically downward, is about 100 meters long, 20 meters wide, and 300 meters deep. At the end, there is a passage about five meters long and wide.

Entering the passage, you can see blackened marks, quite damp, and the ground is watery and muddy.

"My lord! General Li has used flooding, smoking, etc., and the tunnels extend in all directions, attracting water sources to pour in, and I don't know where they are going, so it is useless. Smoke too, it can only slightly block the enemy troops in the tunnels, interrupt and slow down their excavation progress, and the effect is not great!"

Li Yuan, the eldest grandson Shunyi, Cai Yan and others, each leading the way, followed by Wu Xin, was the eight-rank Cao Shen military Chen Ying.

Advancing about 100 meters, the road encountered hundreds of Sui troops, some on guard, some digging or testing.

Arriving at a passage about seven or eight meters long and wide, the plane is full of potholes, obviously different from the passage that comes, and the method of excavation is completely different, which is the tunnel dug by the enemy.

Chen Vulture kept explaining: "My lord, according to speculation, this is a barbarian great sacrifice to drive a special earth-walking beast, excavated with great efficiency. Of course, there are many great monks who can dig through the foundation!"

At this point, the foundation is already faintly visible, and dozens of meters ahead, there is a slightly pale stone, and it is no longer a layer of soil.

"Ahh......h

Suddenly, more than a dozen Sui soldiers in front of Wuxin screamed one after another, falling to the ground and rolling, uncomfortably grasping their bodies, grabbing the blood marks of the Dao Dao, and some even tore off the flesh and blood without knowing it, as if something had entered the body.

"Be careful...... It's a Gu worm!"

The flute demon of the Demon Sect Ancestor, who was captured on the night of the assassination, and then was transformed by the eldest grandson Wuji, reminded nervously.

In the middle of the hand, a flute with a metallic luster, like bone and iron, was in the hand......

Blowing, the sound waves visible to the naked eye, rippling open, the effect is stronger in the channel, countless black spots that are difficult to see with the naked eye appear, as big as a finger, as small as a sesame seed, the number is innumerable!

Everyone was awe-inspired, and they broke out one after another to protect the outer body and the true yuan, and even Chen Eagle also had the outer gang to protect the body.

On the contrary, Wu Xin is the worst, he doesn't even have Wai Gang, and he only recast nearly sixty Earth Demon Acupoints by day and night penance, and it is estimated that it will take half a month to recast seventy-two Acupoints to stimulate Wai Gang!

"Boom ......"

The Blazing Sun Ancestor took a step forward, and the scorching sun martial spirit emerged, swallowing several feet of flames around his body.

"Burning Flames!"

A palm slapped out, and the blazing flames turned into flames that filled the passage and swept out.

The white mist is filled, and the water stains and water vapor in the passage are instantly evaporated, becoming dry and charred black. Even the Sui army, who had died tragically, was burned to the ground, and the smell of burnt meat was pungent.

"Wind!"

Wu Xin's spiritual sense swept away, and with a finger, a miniature tornado vortex several meters large appeared. Sweep along the passage.

Countless sand and dust were swept into the whirlpool, and there were countless small Gu worms that were missed, and they were crushed when they were caught in the whirlpool.

Everyone breathed a sigh of relief, and advanced more than 100 meters, and met two branch passages on the road, and Wu Xin and the others insisted on going to the east.

During this period, Wu Xin and the others saw dozens of corpses, some of which were charred and blackened, obviously poisoned, and some of which were only skeletons and lost all their flesh and blood.

The enemy forces turned out to be in the underground passage. With such a terrifying Gu worm planted, it was no wonder that Li Shimin asked for help.

Except for those who are strong in the late stage of qi refining and above, no matter how many soldiers enter, they will be sent to death!

Stopped, it was a crossroads, all pale stone.

This is already directly below the east city wall of Luoyang, and the geology is all foundations, not rock layers!

Wu Xin looked at the old man of Shanhe, the old man of Shanhe understood, and his heart moved. A three-dimensional underground tunnel map emerges......

It is like a beehive, extending in all directions, and the passage spreads like a spider's web, like a labyrinth. It's dizzy, and it's not directional.

The whole three-dimensional pattern encompasses an area 500 meters long and 2 to 300 meters wide. This is the scope of the spiritual sense of the old man of the mountains and rivers.

"This ...... I can't cut the blockage!"

The Trapping Ancestor was quite troubled and hesitated, his ability is "Trapped". Can cast spells to break down passages and block passages.

However, the surroundings are all stone, the area is the foundation, the top is the city wall, and the bottom is the rock layer, how can this collapse? The Trap Ancestor does not have the strength to shake the east city wall and make it collapse!

"Keep going! Inform the others, and reach the city walls! Let the blacksmith in the city prepare, water the passage with iron juice, and seal it completely!"

Wu Xin's mental power was restless, and countless methods emerged, eliminated, and finally commanded.

In the previous battle, Wu Xin felt that gravity in this world is not intellectual, everything is more direct, lacking wisdom, and the way of fighting is basically straightforward and hard.

After really playing strategy, Wu Xin felt that his wisdom and thinking were a little insufficient.

Just in front of him, Wu Xin couldn't think of an effective way to deal with it.

It can only be blocked, watered with iron juice, the price is very large, I don't believe that the enemy army can still dig through the iron layer.

It can be done, and it can't be done in a short time, the eastern capital Luoyang only needs to hold on until the arrival of the Great Sui reinforcements, which is enough!

Don't look at the enemy's digging of such a huge underground project, the cost, time, energy, etc., must be huge, it is better to directly open or collapse the city wall.

The tunnel operation should have started before the arrival of the Xuangan anti-army. Otherwise, in just a few days, it will not be possible to dig a tunnel of such a scale, even if there are barbarian great sacrifices and earth-walking beasts, it will not be possible!

Along the way, among the dozens of passages, several are relatively quaint and obviously not newly excavated. It should have existed in the barbarian era, and now it is being used by Yang Xuangan!

"Yes!" Chen Hu answered, and ordered a Sui soldier to leave and pass the word.

Everyone continued to move forward, and all kinds of corpses crawled everywhere, including newly dead Sui soldiers, rotten bones, and skeletons that could not judge the time.

The strange thing is that now that nearly half of the foundation has passed, all I see is the Sui army, and I haven't encountered the barbarians!

"Could it be that the tunnel has been discovered and the barbarians have given up?" the nervous Flute Demon muttered in confusion.

The old man of Shanhe naturally responded: "The tunnel is a secret thing, and since it has been discovered, the natural effect has been greatly reduced." As long as our deep ditch barrier is tightly defended, the tunnel is useless!"

Mr. Mingji, who had been silent, shook his head and retorted: "Having said that, could it be that we dig a moat a hundred zhang deep along the inside of the city wall? How long will it take? If the enemy digs deeper? It must be solved from the source! As the lord thinks, it is a good idea to water the outside of the city wall with iron juice, and the cost is a bit large, but it is once and for all! When the time comes, a few more strongholds will be left and people will be sent to supervise them, and the underground raid will be prevented!"

Mr. Mingji and the old man of Shanhe are the two great cultural cultivators who followed Wuxin this time, and they are also the only four great literary cultivators in Wuxin's power.

Jin Operator is in charge of logistics and will not go to the front line, and Mrs. Tulip is in charge of Jurong, and the current situation is fine, and she has not defected and returned to the Demon Gate!

The first update arrives, soliciting all kinds of tactics!

Regardless of whether there is a monthly pass or a recommended ticket, click to vote, a little mind, many people don't know if they have a ticket!

Thanks!(To be continued.) )
