The loud noise outside the laboratory frightened Ou Yanyu and Zhang Shijie into a cold sweat.

It's not that they are cowardly, but An Dong is at a critical juncture at this time, in case this loud noise affects him, one negligence will destroy all the materials in the industrial printer.

These materials are not easy to come by, and if the materials are destroyed, then their work to make energy light armor can only be temporarily stopped, and they have to collect those rare ores again.

But now that the situation outside is outside, there is not so much time left for them.

Between the dungeon and the red power, there is already water and fire, and the situation is extremely tense.

There is also the ambitious Wang family, who is also waiting for an opportunity, as long as Ou Jincheng is not careful, he will be bitten by Wang Tiecheng's neck and will not let go.

In addition to worrying about Andong, they all began to worry about the situation outside. They all knew very well that this loud bang was caused by a strong explosion.

The trembling of the ground just now illustrates this point.

Inside the dungeon, how could there be such a violent explosion?

Moreover, it feels like this explosion point is not too far from them!

What caused the explosion? Or rather, who caused the violent explosion?

In their hearts, there are too many questions and puzzles. But now, they didn't dare to move, so they could only stay quietly in the laboratory, for fear that they would accidentally disturb An Dong again.

Just a dozen seconds after the first violent explosion, the second explosion reached everyone's ears.

"Go and see what's going on out there!" An Dong didn't dare to put down the work in his hand, seized an interval, and quickly said to the two.

The two looked at each other, grabbed their weapons and left the lab.

As soon as they came out, Ou Yanyu and Zhang Shijie were stunned by the scene in front of them.

On the ground, smoke rose and people were exchanging fire.

The courtyard wall of the courtyard collapsed by a small half, and several buildings around it were blown up.

At this time, Da Niu was leading the patrol to resist the attack of a large number of enemies at the corner of the street.

Ou Yanyu and Zhang Shijie quickly moved to Da Niu's side, not knowing what was going on, and hurriedly asked, "What's going on?" ”

"Wang Dali has lost his heart and is attacking here with people!"

"What? How is this possible? Where did he come from? ”

Hearing Da Niu's words, Ou Yanyu was taken aback.

The crazy Wang Dali surprised Ou Yanyu, and what he did also surprised Ou Yanyu, but what surprised Ou Yanyu the most was where Wang Dali got so many people?

Judging by the intensity of this firepower, the number of people on the other side must be no less than a thousand.

A team of 1,000 people is not many in the dungeon.

Each detachment of the urban defense team is organized like this, and each detachment of the urban management team is also organized like this, and then there are action teams within the red force, which are basically like this.

Other than that, there are absolutely no teams of more than 1,000 people in the dungeon.

However, which team is this team outside?

Daring to use force like this in the dungeon would be like a more blatant rebellion. Just ask, who can be so unafraid of death and follow Wang Dali with all his heart?

"I don't know where they came from. However, these people are definitely not people in the dungeon! ”

Da Niu fought back and said to Ou Yanyu.

"What? It's so possible! ”

This time, Ou Yanyu's surprise was far greater than the last time.

Not the people of the dungeon!

So how did they get in?

You must know that after Ou Yanyu disappeared, Ou Jincheng had ordered all entrances and exits to be blocked, and the seal had not been lifted until now.

That is, these people had been in the city a few times before that.

More than a thousand people want to sneak into the dungeon, and it is not an easy task.

There are so many aspects involved, and in order to do this, there must be enough money and time, both of which are indispensable.

Moreover, after these thousand people enter the dungeon, there must be a hiding place that can accommodate them, and there are not many such places in the dungeon.

Also, every link of the 1,000 people eating, drinking, and sleeping is crucial, and if you are not careful, you will be exposed.

Now, Ou Yanyu has to begin to admire the strength of the Wang family. finally understood why his grandfather was so jealous of the Wang family and Wang Tiecheng.

Wang Dali led his subordinates and continued to move forward, gradually forming a trend of encirclement, surrounding the small courtyard to death.

The big bull led the patrol people, and at first they could resist twice.

However, in the hands of Ma Liang and Niu Ming, the patrol team has long been corrupted and rotten, where is there any combat effectiveness!

Within five minutes, most of them were throwing off their armor and hiding inside the fortifications not daring to show their heads, let alone effectively fight back.

In the end, there were only fifty people who could resist desperately.

Fifty to one thousand, such a disparity in strength, even if Zhuge Kongming is reincarnated, it is the same helpless!

Seeing that Wang Dali was about to attack the small courtyard with people, Ou Yanyu, who retreated to the courtyard, reminded Da Niu and said, "It's not okay to fight like this, we have to think of a way quickly!" ”

"Now, what else can be done! can only resist desperately and wait for someone to support. Da Niu said as he fought back.

If it weren't for the advantage of terrain, they would have been given a nest by Wang Dali a long time ago.

The small courtyard is in a special location, one side is close to the courtyard wall of the city defense team, the other side is a dense residential area, and behind it is an underground river, and only the front can be used for ground attack.

Therefore, Wang Dali could only enter the courtyard through the gap in the courtyard wall that he had blown down.

The gap in the courtyard wall is not large, although Wang Dali and they have many people, but there are not many effective attacks.

This is also the reason why the big bulls have not been eliminated by the enemy for a long time.

However, there is no way to continue thinking like this!

Da Niu has a limited number of people, and with the fierce charge of the enemy, the attrition is very serious, as long as the opponent is coming three or two effective charges, Da Niu will become a bare-bones commander.

"Capture the thief and capture the king first, you two concentrate your firepower to cover me, I'm going to capture Wang Dali alive!"

Da Niu also knew that it would not work like this, but after thinking about it, he only thought of such a method.

"No, the enemy's firepower is too fierce, and you won't have much of a chance. Moreover, Wang Dali is not an ordinary person, and it will not be so easy to capture him alive. ”

Ou Yanyu asserted that he rejected Da Niu's idea, and he rushed out so rashly that it was tantamount to sending him to death directly.

Zhang Shijie also said to Da Niu: "Yes, Da Niu, you can't go out like this, the enemy's vitality is too fierce, and you can't find a chance at all!" ”

However, the situation is so critical that if no one stands up to turn the tide, then they will have to sit back and wait.

Just when the three of them were in a dilemma, they suddenly heard a familiar voice:

"TMD, is Wang Dali crazy about losing his mind?"

Ou Yanyu exclaimed: "An Dong, you are out!" ”

"Is the synthesis of materials successful?" Zhang Shijie asked.

"You've finally come out, and I'll leave it to you. I'm a poor donkey, and I have nothing to do! ”

As soon as he saw An Dong, Da Niu breathed a sigh of relief, and his burden could finally be lifted.

Some people have such an ability, as long as they appear, no matter what kind of difficulties they have, they can calmly face them and solve them.

As soon as he appears, he can put everyone at ease.

An Dong has such a charm, and of course, he also has such strength.

"Isn't Wang Dali crazy? There were about a thousand people on the other side, all of whom he had snuck in from the outside. The strength is very average, but there are many people, and our wine bags and rice bags have long been collapsed, and these people are still a little backbone, and they are desperately resisting with me! ”

Da Niu briefly introduced the battle situation to An Dong, so that he could quickly grasp the current situation of the enemy and the enemy, so that he could make the best response.

"Hmph, they are all vulnerable paper tigers, Mengmeng people are okay, really do it, don't be afraid."

An Dong carefully observed the situation on the battlefield, then returned to the fortifications, and said to Da Niu with a cold snort.

If An Dong led people to attack such a courtyard, let alone give him a thousand people, even a hundred people, the battle would have ended long ago.

It can be seen that Wang Dali's command level is average, and the level of people he brings is even more ordinary.

"Where is Grandpa Wu?"

"It's very safe in the safe house inside, unless Wang vigorously uses heavy weapons, don't think about getting a single hair from the five doctors!"

"Then I don't have to worry about it, I can give it a go!"

Knowing that Wu Ping was very safe, An Dong rolled up his sleeves, then smiled indifferently, and said to the three of them: "In a while, I will go out and capture Wang Dali, and you can cover up with vitality." ”

"No way!" The three of them spoke almost in unison, asserting that they vetoed An Dong's decision.

Seeing that the three of them were so unified and resolute, An Dong was a little surprised and puzzled, and asked, "What's wrong with you?" ”

"Just now, I wanted to do this, but they vetoed it again." Da Niu explained.

"Haha, didn't I go this time, what are you worried about?"

With that, An Dong miraculously disappeared in front of the eyes of the three of them.

Ou Yanyu had seen An Dong appear out of thin air once, so he was used to disappearing out of thin air this time.

However, it was the first time for Da Niu and Zhang Shijie to see such a magic skill, and their faces were unbelievable, and they could stuff a few eggs into their mouths.

What's going on?

Blinded? No!

Delusional? Of course not!

Then it must be magic, a big change! Like, it's not quite right.

"Why are you stunned? Don't come over to cover for Andong? Ou Yanyu fought for a while, only to find that Da Niu and Zhang Shijie were still stunned in place, and turned around and shouted to them loudly.

Hearing Ou Yanyu's shout, the two of them came to their senses. I wanted to provide fire support to An Dong, but as soon as I showed my head, I saw a black shadow falling from the sky and falling in front of their eyes.

With a "bang", the dust was flying, and the choked Zhang Shijie couldn't help but sneeze.

The three of them looked at each other and couldn't help but be overjoyed.

It turned out that it was Wang Dali himself who fell to the ground.
