Fu Ziyan looked forward in surprise, and along the turret window, she suddenly found that the water level of the moat had dropped by more than a meter in a short period of time!

It is indeed a very amazing thing that the water of the river, which was originally level with the riverbank, has been reduced so much at once.

"This is ......" Fu Ziyan's beautiful eyes were stunned.

"The moat of Fengyan City is a second-class moat, about 4.5 meters wide and 6 meters deep, and the bottom of the river is also densely covered with sharp iron thorns, and if you want to attack the city, you must first fill in the moat. But for now, instead of waiting for the enemy to fill in the moat, let's use it to do something first. Li Ming said with a smile.

"You're going to empty the river?" Fu Ziyan asked puzzled.

"Yes, before today's battle, I have asked Xiao Kun to secretly dig a tunnel in the city with the craftsman that leads directly to the bottom of the moat, and set up an underground culvert there, as long as the mechanism is opened, the river will be completely emptied along the culvert. But I also had him dig another dark river that connected to a warehouse where large quantities of black oil were stored. Li Ming smiled.

"I see, you're going to fire again?" Fu Ziyan's eyes widened in surprise.

"Yes, the use of this black oil is to defend the enemy's siege convoy close to the city wall, as long as the black oil is ignited, the outside of the city will immediately become a river of fire, and all the nearby siege vehicles will be burned, which can be regarded as a surprise we gave the enemy in Fengyan City at the end." Li Ming smiled and nodded.

"That's a lot of money, when did you prepare so much black oil?" Fu Ziyan asked in surprise.

"Since half a month ago, every day I have people send a few barrels of black oil to Fengyan City, just in case the enemy is trying to seize the city again. Now you just have to wait and see the show, and hopefully we can destroy more siege vehicles......" Li Ming said.

In the current stage of camp warfare, Li Ming knew that the battle for the city was the biggest battle, and the greatest threat to the city tower in the city battle was the professional equipment such as the siege vehicle.

If you can reduce the number of siege engines of your opponent as much as possible at a small cost, you can prevent other cities from being in more danger in future battles.

And Li Ming knows very well that building a high-level siege vehicle is not a simple matter, the various materials it needs are very difficult to get together, and the time required by craftsmen to build a siege vehicle is also very long, and the enemy will have to wait at least a week or more if he wants to restore the number of siege vehicles.

"With so much black oil, it must be able to destroy a lot of siege vehicles, these siege vehicles are too high in defense, and it is too difficult to destroy them normally, I support Brother Ming's plan." Fu Ziyan said excitedly.

While the two were talking, the water in the moat lowered to a depth of two or three meters again, revealing dense sharp iron thorns......

At this time, the enemy's rear shield armor vehicles continued to advance, and the dense chaos players were hiding behind the shield armor body, ready to rush forward to fill the moat.

When Li Ming saw this scene, he hurriedly issued an order in the alliance channel.

"Xiao Kun, don't be in a hurry to put in the black oil, the enemy has already come up, let them fill in the stones first, and it will just happen that our black oil will flood the river bank faster." Li Ming said immediately.

"Knowing Brother Ming, then we will listen to your instructions, and you said that we can act again." Kun Shao hurriedly replied.

Having received an order, the moat was now only releasing water outward, but it did not flow directly into the black oil, and soon, the moat outside the city walls had turned into a deep trench......

The two layers of shield armor vehicles outside the city gradually approached, and the Chaos players quickly rushed out of the second row of shield armor according to the instructions, and rushed directly to the vicinity of the siege vehicles......

Countless dense black dots frantically rushed towards the vicinity of the moat, under the dense rain of arrows and stone bullets, as well as the light bullets that quickly exploded when they landed, a large number of chaos players screamed and fell to the ground, and twenty or thirty people out of a hundred people could rush to the front of the first layer of shield armor, they were already very lucky guys.

Looking at the corpses all over the ground outside the city, but there were still countless enemies rushing forward frantically, rushing to the front of the city tower one after another, Fu Ziyan had already seen a helpless face.

"War...... It's cruel. Fu Ziyan sighed.

"Since ancient times, all battles have been like this, so peace is the most important ......," Li Ming nodded and sighed.

Seeing groups of players rushing behind the first layer of shield armor at the risk of death, they finally ensured their own safety, but their mission was not yet completed, and they had to continue the adventure......

After a few seconds of staying in the safety behind the shield, the players once again moved forward through the gap in the shield-armored cart and rushed directly to the bank of the moat, opening their packages ready to throw stones......

But the moment they rushed to the bank of the moat, everyone couldn't help but be a little stunned by what they saw in front of them.

Because the moat they saw had all dried up!

"Boss of the sub-group, what's the situation, the moat is out of water?"

"Whether it has water or not, our mission is to fill the moat so that the siege engines can attack the towers smoothly, just do what is ordered."

At the beckoning of their respective sub-leaders, all the Chaos players who risked their lives immediately threw stones into the moat......

Thundered!

Cracking sound!

All of a sudden, rolling stones could be seen everywhere in the entire moat, and dense black spots continued to fall into deep ditches, accumulating layer by layer, and the entire moat was being quickly filled with stones.

"They're moving pretty fast, and they're about to fill the moat." Fu Ziyan's eyes straightened.

"Fortunately, this is the game world, if it is really an ancient battlefield, it is not something that can be done in a day or two if you want to fill a moat." Li Ming said with a smile.

"Is it possible to import black oil now?" Fu Ziyan asked excitedly.

"Wait a little longer, let them continue to fill up a little bit, and then the black oil will spread directly onto the riverbank and spread out faster." Li Ming groaned.

The moat outside the city is a low gentle slope, and once the black oil overflows the riverbank, it will automatically flow towards the low-lying area, which happens to the area where siege engines and shield vehicles are concentrated......

Originally, his plan was to burn the siege equipment that was attacking close to the tower, but he did not expect that the enemy could have such an effect by filling the moat......

Quietly waiting, seeing that the stones have filled the moat, only half a meter away from completely turning the deep ditch into a path.

"Xiao Kun, you can import black oil!" Li Ming immediately issued an order.

"Understood." Kun Shao replied with a smile.

Several commanders who had been waiting for a long time received orders to immediately open the underground passage mechanism.

In a warehouse building on the ground not far away, a large group of players immediately worked in groups of three or four, lifted the huge wooden barrels stored in the warehouse, and rolled to a pool, which was empty, except for the passage to the underground on one side.

Whoa!

As countless wooden barrels uncorked, splashes of black oil juice fell into the pool, and the black oil gathered more and more, and flowed quickly towards the black hole......
