Looking at the arrogant enemy generals below, the soldiers on the city wall were eager to fire their weapons and kill all the enemy soldiers below.

"All the soldiers obey the order and blow up the enemy general below who is arrogantly shouting with a loudspeaker."

Di Mei stood on the city wall, her long brown hair was a little messy by the wind, and her pretty face showed anger.

The enemy soldiers below are very arrogant, and they have also set up black cannons, ready to attack Technopolis at any time.

"Boom!"

Shells were fired, charging at the enemy soldiers below with flames.

The enemy soldiers below were also ready at any time, and when they saw the shells roaring and flying like raindrops, they immediately returned fire.

The cannon erected by the enemy also spewed out tongues of fire and flew towards the science and technology city.

The war began, and the deafening sound of artillery continued to sound.

An energy shield rose above Technopol, and the cannonballs landed on the shield, causing no damage to the team.

This is the energy shield that Lin Guoguo has recently researched, and it was originally intended to be used to deal with evil spirits, but he didn't expect it to play a big role today.

In front of Lin Nianzhen's troops, a light red light curtain suddenly appeared, blocking the shells, and the shells exploded on the light curtain without hurting the enemy soldiers.

It was the master of the Mixed Yuan Sect sent by Lin Nianzhen who held up the light curtain, and in order to protect the soldiers who had been on the side, they did not hesitate to waste mana and propped up a protective shield.

Seeing that the enemy had also raised the shield, Di Mei pointed down and said in surprise: "Could it be that Professor Lin gave the energy shield he researched to Lin Nianzhen?" ”

Runde took the binoculars and looked at them, and then said, "No, the energy shield they held up was not provided by our Science and Technology City, but a spell jointly cast by the masters among them. ”

Di Mei took the telescope handed over by Runde, looked at the enemy camp a few hundred meters in front of her, and found that the masters hidden among the soldiers, those masters were holding magic weapons, and red light came out of the magic weapons, gathered together, and formed a large light curtain in front.

"It seems that they are really here to destroy our science and technology city! Hurry up the firepower, they won't last long. Seeing that the cannonballs could not cause damage to the enemy, Di Mei was a little anxious and shouted to the soldiers on the city wall.

The officers and men of the other side received the order and increased their firepower, and the shells flew towards the enemy's protective shield as if they did not want money.

Some time ago, the protective shield was only made to prevent evil spirits, not to prevent shells, although it played a role, but it could not last.

The energy shield that Lin Guoguo studied had not yet matured, and so many shells flew over and lasted for more than ten minutes, and it was already a little unbearable.

The enemy's masters who held up the shield were also uncomfortable, their faces were sweating profusely, and they all felt a little powerless.

When a cannonball from Techno City smashed, their shield shattered, and the shock wave of the explosion blasted the nearby soldiers into the air.

The enemy also dug trenches at this time, and the soldiers hid in the trenches. They were not stupid either, knowing that the shield would not last long, so the enemy soldiers dug trenches in the shortest possible time.

At this time, Lin Guoguo was sitting in the command center, looking at the two warring sides on the screen, he was very confident in the defense of the Science and Technology City, and he laughed out loud when he saw the shield held up by the enemy master broken. When he saw that the energy shield was very weak, he quickly suppressed his smile. He counted the time, and then a smile appeared on his face, and the laughter was louder than before, looking a little yin and a little lewd.

Di Mei was also happy to see the enemy's shield broken, but she was not happy for long, and the shield on the other side also shattered.

"Everyone, hide in the house and stay safe." Di Mei said loudly.

On the city wall more than ten meters wide, rows of alloy houses are built, which can resist the attack of artillery shells and protect the personnel of the party.

Di Mei secretly scolded Lin Guoguo in her heart, this is too pit, there is no shield, the shells are not long-sighted, and there will definitely be a lot of casualties, which she does not want to see.

"Don't panic, their weapons are all tampered with, and the time should be about the same." Lin Guoli's voice sounded in Di Mei's headphones.

"Grandpa the pit goods, I really have you, now I'm relieved." Di Mei also hid in the Jinhe house and replied with a smile.

"Dimei, what did Professor Lin say to you? It's all this time, and you can still laugh. Runde asked in surprise. Although he knew that Lin Guoguo must have a backhand, he really couldn't think of what this backhand was.

"Boom!"

The enemy shell just landed on the alloy house where Di Mei and Runde were, and they felt a strong tremor, and Cher clutched Runde's clothes tightly, looking very scared in her heart.

Although the shields on both sides were shattered, the gunfire never stopped.

After a few minutes, the number of shells fired by the enemy decreased.

"Report to the marshal, the cannon cannot be used." The enemy's non-commissioned officers constantly reported the bad situation to their marshal Dongfang Jian.

Dongfang Jian was surprised, the barrel of the cannon had been deformed and could no longer be used due to the excessive number of shells fired, and the internal structure of some cannons was automatically broken and could not be fired.

This made him very incomprehensible, it was normal to use it before, it has never been broken, why did it go wrong at a critical moment?

In the past, when he was engaged in military training, Dongfang Sword did not keep letting the cannon fire for such a long time, so he didn't find that there would be a problem.

Thinking of the consequences of defeat, Dongfang Jian couldn't sit still and wanted to check it out in person, but was stopped by his generals.

All of this is Lin Guoguo's hands and feet, the materials used in the cannon tube are all defective, and the internal parts are also defective, and the pit goods are calculated accurately Lin Nianzhen's generals will not stupidly pull the cannon and fire it for more than ten minutes in a row, because all that is fired is money, so the weapons he used will not be found when the war is going on.

More and more cannons could not be fired, and when the last cannon fired a shell, it was also damaged.

"It's really unreasonable, when we bought the cannon, the people in the Science and Technology City also boasted that the cannon could be fired continuously for a day and a night, and it was all dumb in just over ten minutes, what a fucking pit."

The beard on Marshal Dongfangjian's face stood up, his eyes widened, and he kicked the cannon sent to him fiercely, and the cannon was kicked out several meters away by him, you can imagine how big his anger was.

The enemy's artillery was all silent, and Di Mei's face showed an excited smile.

"Marshal Runde, their cannons are all useless, and grandpa is really good at pitting people." Di Mei said to Runde with a smile.

"Di Mei, are you talking bad about grandpa again? Be careful I spank you. Lin Guoguo's laughter came from Di Mei's headphones.

"Ahh Grandpa Pit, how can you eavesdrop on me. Di Mei only remembered at this time that for the convenience of command, she and Professor Lin had been connected.
