Luoyang East City Wall.?

I thought the anti-military army would give face, but I did not take any action during Duke Wu's engagement Japan, but who knew it was a secret of the situation.

Wu Xin naturally could not underestimate him, so he took the old man Shanhe, the ancestor Xiankong and other dozen cultivators to the East City Wall. The silver armored Wuwei and others continued to train in the Duke of Wu's Mansion.

At this time, Li Yuan, Duke of Tang, Changsun Shunyi and 40,000 martial arts people had arrived. There were about 200 great monks, and the rest were in the middle and late stages of Qi Refining.

This is the first time that Wu Xin has seen so many great monks gather. If a martial arts conference is held, the majestic momentum will make the air a little slow, the atmosphere will be solemn and depressing, and it will be difficult for ordinary people to get close to.

The territory of the Great Sui Empire originally had nine provinces and forty-nine prefectures. After implementing the two-level system of counties, it was divided into 365 counties and more than 2,000 counties.

There are about 2,000 great monks in the world, and each great monk can dominate one side and can be called the ancestor, so there is a saying that the ancestor of the god refining the gods is said to be.

On average, there is about one great monk in each county, which is quite a coincidence and magical. Perhaps it is because of the illusory fortune problem that the fortune of a county can only provide for a great monk.

Now, the eastern capital Luoyang has gathered about 500 great monks, that is, nearly one-quarter of the great monks in the world.

This is the land of storm.

Of course, except for the barbarians, they are basically in poor mountains, bad waters or remote and deserted places, and are rarely visited. Most of the great barbarian monks are not included in the records of the Great Sui Empire. No one knows how many, and there are definitely not as many as the Great Sui Empire!

About five hundred meters away from the East City Wall, there are military soldiers and simple wooden railings to guard the war.

"Master!"

"Stay Left Behind!"

When Wu Xin arrived, Changsun Shunyi, Li Yuan, Fengjun Commander Cai Yan and others greeted him.

Wu Xin nodded with his eyebrows and nodded, and did not care about being polite, so he observed the environment...

Every five hundred meters, a stream of people was coming and going, transporting earth, rocks and other objects. Looking around, the scene was hot and noisy.

Countless soldiers were digging deep trenches about a hundred meters long, about twenty or thirty meters wide, and unknown depth.

On the banks of the ravines, the land swamps and firewood piled up.?WShu·1ka?n Thick smoke rolled, and some deep ravines were constantly coming and going, emitting bloody smell.

"How is the situation?" After checking, Wu Xin looked at Cai Yan and asked.

Cai Yan's self-judged report: "The anti-army dispatched the barbarian high priests. They drove the earth-like beasts and great monks to dig countless tunnels and have all the channels. Fortunately, General Li was wary and allowed people to monitor the underground and notice it in time. He chose a place to dig trenches and intercept and explore it. It was only then that the enemy had dug countless tunnels. Now the two sides are fighting underground, and the situation is temporarily unclear. General Li is also in the tunnel..."

"Dig countless tunnels? How deep is it?" Wu Xin asked with a frown.

When building a city wall, you don’t just pile up stones on the ground. It’s similar to building a house. You need to choose a place to build it, and you need corresponding foundation support, otherwise it will easily collapse.

The Tiandu-level city wall, which is more than 300 meters high in the eastern capital, has a foundation of at least 100 meters. Even deeper, there is a hard rock layer. Digging tunnels is more difficult than digging rocks.

However, thinking about the strength of the great monk, Wu Xin felt relieved.

Not to mention the great monks, as long as the Qi-refining powerhouses are held, they can dig through the foundation and rock layers!

Cai Yan responded consciously: "The depth is about a hundred feet. A total of twenty-seven places were dug, of which twenty-four were dug into tunnels!"

“Twenty-four places…”

Wu Xin murmured with a heavy expression. Unexpectedly, there were so many, so he looked at Li Yuan and Changsun Shunyi and suggested: "We will separate. We will send eight to ten great monks to command the commander at each place, and contact us at any time. How about it?"

"yes!"

Although it was a suggestion, Wu Xin was left behind by Dongdu, and his decision was not too outrageous or stupid, so everyone would naturally not refute or refuse.

...

A moment later, Wu Xin brought the twelve great monks who followed him into a larger tunnel in the middle.

The entrance to this tunnel is vertically downward, about a hundred meters long, twenty meters wide, and three hundred meters deep. At the end, it is a passage of about five meters long and width.

When you enter the passage, you can see traces of blackening, which are quite wet, and the ground is covered with water and mud.

"Sir! General Li has used flooding, smoke, etc. The tunnel is connected in all directions, which attracts water sources to flow in. I don't know where it flows, so it is useless. C smoke is also so it can only slightly block the enemy troops in the tunnel, interrupt and slow down their excavation progress, and the effect is not great!"

Li Yuan, Changsun Shunyi, Cai Yan and others led the way. The one who followed Wu Xin was the eighth-rank Cao Shen Military Chen Ji.

The advance was about a hundred meters, and hundreds of Sui troops encountered on the road, some were on guard, and some were digging or testing.

Arriving at a passage about seven or eight meters long and wide, the plane was bumpy and obviously different from the passage you came from, and the excavation method was completely different. This was the tunnel excavated by the enemy.

Chen Ji kept explaining: "Sir! According to speculation, this is a barbarian priest who drives special earth-moving beasts to dig out, which is extremely efficient. Of course, there are many great monks among them to dig through the foundation!"

When we arrived at this area, the foundation was vaguely visible. Tens of meters ahead were slightly pale stone, not soil layers.

"Ah, ah..."

Suddenly, more than a dozen Sui soldiers in front of Wu Xin screamed and rolled on the ground, squeezing their bodies uncomfortable, and scratching them out blood marks. Some even tore off their flesh and blood without knowing it, as if something had entered their body.

"Be careful... it's a Gu insect!"

The Demon, the Demon ancestor of the Demon Sect, was captured during the assassination night and then transformed by Changsun Wugui, nervously reminded.

When I turned my hand, I bought a flute with a metallic luster and bone-like iron...

When the sound waves that are visible to the naked eye ripples and opens, the effect is stronger in the channel. Countless black dots that are difficult to see with the naked eye appear, as big as fingers and as small as sesame seeds, and the number is uncountable!

Everyone was shocked and burst out with external energy and true energy to protect their bodies. Even Chen Ji also had external energy to protect their bodies.

On the contrary, Wu Xin was the worst. He didn’t even have an external gang. He only recasted nearly sixty Earth Evil acupoints after practicing hard day and night. It is estimated that it will take half a month to recast seventy-two acupoints to stimulate the external gang!

"boom……"

The ancestor of Lieyang took a step forward, and the martial soul of the scorching sun emerged, and he sucked and spitted several feet of flames all over his body.

"The world of flames!"

With a palm, the blazing flame turned into flames to fill the passage and swept out.

The white mist was filled with water stains, water vapor, etc. in the passage were instantly steamed, and it became dry and charred. Even the Sui army, who had already died tragically, was burned to charred corpses, and the smell of scorched meat was pungent.

"wind!"

Wu Xin swept his spiritual consciousness and pointed out with one point, a vortex of several meters of micro tornado emerged and swept along the passage.

Countless sand and dust were swept into the vortex, and countless small insects were missed. When swept into the vortex, they were swept into pieces.

Everyone breathed a sigh of relief and advanced more than a hundred meters. When they encountered two branch passages on the way, Wu Xin and others insisted on going east.

During this period, Wu Xin and others saw dozens of corpses, some of which were charred and obviously seriously poisoned; some were left with only bones and all flesh and blood were lost.

The enemy actually laid such a terrifying insect in the underground passage. No wonder Li Shimin asked for help.

In addition to those who are strong in the late stage of Qi Refining or above, no matter how many soldiers enter, they will die!

Stop, it was a crossroads, all of which were pale stone.

This is already directly under the Luoyang East City Wall, and the geology is all foundations, not rock layers!

Wu Xin looked at the old man in Shanhe. The old man in Shanhe understood, and his literary heart moved, and a three-dimensional underground passage map appeared...

It looks like a honeycomb, with all directions. The passage spreads like a spider web, like a maze, making people dizzy and unable to tell the direction.

The entire three-dimensional pattern covers an area of ​​500 meters long and 200 meters wide. This is the spiritual exploration and range of the old man in Shanhe.

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

The ancestor Xiankong was quite troubled and hesitated. His ability was to "Xiankong", which could cast spells to destroy the passage and block the passage.

However, the surroundings are full of stone, the area where they are located is the foundation, the city wall above, and the rock layer below, how can this be destroyed? The ancestor Xiankong did not have the strength to shake the East City Wall and cause it to collapse!

"Continue to move forward! Notify others and reach the area of ​​the city wall! Let the blacksmith in the city prepare and water the passage with iron juice. Completely seal it!"

Wu Xin was restless in his mental power, and countless methods emerged, eliminated, and finally ordered.

In the previous battle, Wu Xin felt that the gravity of this world did not value wisdom, everything was more direct and lacked wisdom, and his fighting style was basically straightforward and forced to fight.

After really playing with strategy, Wu Xin felt that his wisdom and thinking were not enough.

Wu Xin could not think of an effective way to deal with the tunnel battle just in front of him.

I can only block it and water it with iron juice. The price is very high. I don’t believe that the enemy can still dig through the iron layer.

It cannot be done in a short time. The eastern capital Luoyang only needs to persevere until the arrival of the Great Sui reinforcements, which is enough!

Although the enemy's dig out such a huge underground project, the cost, time, energy, etc. will definitely be extremely expensive, it is better to directly open up or collapse the city wall.

The tunnel operation should have started before the arrival of the Xuangan Anti-Japanese Army. Otherwise, in just a few days, the tunnel of such a scale would not be dug out, even if there were high priests of barbarians and earth-moving beasts, it would not be possible!

Along the way, there were several of the dozens of passages that were relatively simple, obviously not new excavations. They should have existed in the era of the barbarians and are now being used by Yang Xuangan!

"Yes!" Chen Ji responded and ordered a Sui army to leave and communicate.

Everyone continued to move forward, and various corpses crawled everywhere, including the newly dead Sui army, the rotten corpses, and the bones that could not be judged by time.

What’s strange is that nearly half of the foundation has been passed through, and all the Sui army are seen are, but they have not encountered the barbarians!

"Did the barbarians give up?" The nervous and alert Demon muttered in confusion.

The old man Shanhe naturally said: "Authentic is a secret matter. Since it has been revealed, its natural effect will be greatly reduced. As long as we have deep grooves and tight defenses, authenticity is useless at all!"

Mr. Mingji, who had been silent, shook his head and retorted: "With that being said, can we dig a moat a hundred feet deep along the inner side of the city wall? How long will it take? What if the enemy dig deeper? It must be solved from the source! The lord thought that it would be a good idea to water the outside of the city wall with iron juice. The price is a bit high, but it is a one-time and for all! Leave a few strongholds and send someone to supervise, and you can prevent the underground raids!"

Mr. Mingji and Shanhe Lao Ren are two great literary cultivators who followed Wu Xin this time, and are also the only four great literary cultivators in Wu Xin's power.

Suanzi Jin is responsible for the logistics and will not go to the front line; Mrs. Tulip is in charge of Jurong, and the situation is still fine at present, and she has not rebelled and returned to the Demon Sect!
