The fat zombie has arrived in the middle of the bridge and is about to rush across the bridge deck. Li Yuanhong yells to Lu Pang: "fat man, you and I are responsible for a bridge. You must not let the fat zombie cross the bridge, otherwise the bridge will not be held!"

"Brother Li, what about two bridges?" Lu asked anxiously.

"Don't worry about it. The two bridges are in charge of commander Xing's troops. If we guard the two bridges, we will share their worries."

"Well, here comes Ming!" Lu Pang was reluctant. When he met with the zombie fat man, he still suffered losses. After all, his height was not as high as that of the fat zombie. Moreover, the strength of the fat zombie was also large. It was not easy to take these soldiers to guard the bridge by himself.

When the two sides were drawing their arrows, three more airships came from the sky. These three search airships are not of the same type as the airships currently used by Li Yuanhong. Their bodies are more slender, and they are only two stories high. Judging from the speed of airships, they are one third faster than the current airships. The airship flew over the battlefield and fell directly to three bridge decks. When it was half a meter away from the bridge deck, the airship suspended and stopped. Then the side chord firing port of the airship was opened, and several dark magic cannons were pushed out. Then the magic gun fired at the corpses coming from the bridge deck.

Li Yuanhong had no time to stop it. He could only close his eyes and said to himself, "it's over. The three bridges are finished."

But after a long time, he didn't hear the collapse of the bridge. Li opened his eyes and saw that the bridge was in good condition. Many charred corpses were left on the bridge deck, and those fat zombies could not escape the burning fate. Even if some of them were not burned, they were burned by fire and lost their fighting ability.

Li Yuanhong just closed his eyes and didn't notice how it happened. He just opened his mouth and looked at it in surprise. After shooting, the three airships did not stop. Instead, they took off directly and flew to the third bridge. Then the ship's bow thought of the corpses and lined up on the bridge. When the distance from the surface was less than half a meter, the spacecraft stopped, and suddenly a shooting hole appeared. A magic gun came out from the shooting port. With the flash of the magic gun muzzle, a fireball shot out of the muzzle.

Li Yuanhong opened his eyes and couldn't believe it. Isn't this the Longkou gun? The biggest feature of this kind of gun is that it can kill in a straight line, rather than in a direct explosive way. This kind of gun is most suitable for dealing with enemies in a straight line, and it is more suitable to defend the city and bridge. Li Yuanhong thought that it would take at least half a year to develop this kind of gun. Unexpectedly, only a few months later, the finished product would come out.

After the three shells are fired, the zombies on the bridge deck will be burned to fly ash as long as they are in front of the shells. Moreover, no matter what grade of zombie you are, even if you are a fat man with thick skin and protective armor, it can't stop the damage of the magic gun. Soon the bridge deck becomes smooth and smooth, and even the corpses piled up on the bridge deck are cleaned up Yes.

As the corpses on the four bridges disappeared, there was a roar of corpses in the center of Harbin city. The zombies still gathered on the bridge deck were suddenly removed, as if the zombies had given up their attack on the bridge. Of course, Li Yuanhong will never believe that zombies will give up easily, especially in the North Bank of the river, there are a large number of zombies waiting for him to rescue, unless giant zombies intend to give up those zombies.

However, Li Yuanhong is not afraid. Li Yuanhong will do his best to do what the other side can do. Now the zombie stops attacking. It is just at this time that he takes a good rest. Although Li Yuanhong has not directly participated in the war since the morning However, it was tiring to build defense towers everywhere, including commanding and supervising logistics airships to transport materials. Li Yuanhong did not know the origin of these three sudden airships.

Seeing the zombie receded, the three airships took off one after another, then flew to Li Yuanhong's Island and slowly fell down. The cabin doors of the three airships opened slowly. In each door, an old man came out. They were three old urchins in the magic tower.

The three old men stepped out of the airship. Dr. yuan and the old magician all looked as usual, but Dr. Dubai's face turned white and he just vomited. When the two old men saw Dr. Bai like this, they were not only not comforted, but also laughed: "I said that old white head, so soon it will not work!"?! Don't you say you want to show your style to the sky! Is this your heroism. Ha ha ha

Seeing the two old men so ridiculed, Dr. Bai did not get angry. He said faintly, "I am experiencing the thrill of flying at top speed. Your two spaceships are slow. If I hadn't been waiting for you for a moment, you two would not have known where I left you. It's no wonder that you two are not seasick at the speed of your turtle climbing!"

"Old white head, don't sell yourself cheap. We were just testing the stability and system compatibility of airship, but we haven't reached the limit of testing airship. We call it steady. We don't want to be impatient and make ourselves miserable!"

As soon as they saw that they were going to be sun Liu alliance and Cao Cao, Li Yuanhong quickly came forward and said, "ouch, what's the wind with the three old people?"

As soon as the three old people heard Li Yuanhong's question, they turned their heads and looked at Li Yuanhong, and then said in one voice, "it's not for you!"

"For me?" Some of Li Yuanhong's father-in-law monks are confused."Last time, didn't you say that the three of us had to choose two from three to study the gun? Now it's a month, and it's time to choose the one who is eliminated, so I'm looking for you to be the judge!" Dr. Bai was a little more relaxed at this time, so he said to Li Yuanhong.

When Li Yuanhong frowned, he almost forgot this stubble. Unexpectedly, these three old guys are really good children's temperaments. They are stubborn. They are really a road to the dark.

"And what are you going to compare?" Li Yuanhong asked.

"Take the gun from the ship." Dr. Yuan pointed to the spaceship.

"Yes, take the guns on the ship." Said the old magician.

Li Yuanhong is in some difficulties. If he is allowed to make his own evaluation, it is not good to offend anyone, but he has to make a judgment. When Li Yuanhong was in trouble, suddenly zombies appeared on the four bridges at the same time, which meant that the zombie attack was about to begin. If you don't quickly find a way to solve the problem of the three old urchins, then you will be caught by three old guys, and you will not be able to direct the battle. Moreover, depending on the situation, the three old people will not give up until they solve the problem. They must find a way to get the best of both worlds.

Li Yuanhong's eyes turned and he had a way. Then he said to the three old men, "it's very simple to evaluate the quality of your three guns. Just take out the indicators of each of the three guns and compare them."

"Nonsense, if the indicators of those two old guys are reliable, we can still find you!" Dr. Bai spoke first.

"Yes, those two guys must have made a mistake in their own data." Said Dr. white.

"That's right. The two old men, who have no rigorous attitude that a magician should have, dare to take out the data arranged casually!" The three began to fight again.

"Stop, stop You come to me to solve the problem, and let me speak! " Li Yuanhong yelled, and the three old men immediately shut up.

"I'll give you a method. In this way, which of you will test each other, and then compare the results of the three tests. If there is no deviation, it means that no one is faking. If there is a deviation, the weighted average of the three will be used, so that the data will not deviate too much. What do you think of the comparison?"

As soon as Li Yuanhong's idea came out, the three old fellows immediately agreed: "good idea. I want them to see whose gun is the real Longkou gun."

"Good idea. I want them to see how perfect my data is."

"It's a good idea. I'll see how bad these two guys are in the end."

The three men nodded and agreed, then turned to their own airship. Li Yuanhong quickly called out, "wait a minute, what are you going to do?"

Of course, the three old friends said, "of course, it's back to the laboratory to test the data."

Li Yuanhong heard that you are gone. Who will guard the bridge for me? No, I can't let you three go. I'll stay to help me guard the bridge, but I can't say it openly. If I say it openly, these three people will not buy it, but they will give themselves a big label of "greatly damaged conscience". Li Yuanhong's heart and eyes turned rapidly, and he soon had an idea.

"It's a waste of time for the three of you to go back and forth, and only in the actual combat can we find out the advantages and disadvantages of the artillery. If you go back, you might as well test here. In addition, there is an advantage here, that is, there are physical targets available, and the artillery effect will be clear at a glance. At that time, you can also do some limit tests, such as testing how many shells are fired continuously by the barrel You need to rest. How many shells are fired continuously will reduce the accuracy of the barrel. These are important parameters of the artillery. If you test in the laboratory, there may be no complex environment like battlefield, and many shortcomings will be hidden. Don't you want to know what defects you haven't found in your artillery? "

Li Yuanhong's words also mentioned the heart of the three old people. After all, people engaged in research always have a character of pursuing perfection. When Li Yuanhong fooled him, the three old people agreed. So the three old people boarded the spaceship again, but this time it was someone else's. then the spaceship started to fly to the bridge. Soon, the fireball swept across the bridge again Scene. At this point, Li Yuanhong's heart just let down, it seems that the bridge is no longer worried.

The battle lasted for a whole afternoon. During this period, the three old men changed their spaceships and began to test them tirelessly. The zombies sent not only fat zombies, but also long tongued zombies, shadow zombies and other mutant zombies. In particular, the long tongued zombies crept under the bridge to sneak attacks. Li Yuanhong had encountered this situation many times Prepare, these crawling zombies are locked by the magic defense tower before they get to the middle of the bridge. Even if there is any leakage, they will be killed by magic gun soldiers.

In order to recapture the four bridges, the zombies sent nearly three million zombies. As a result, the bridge deck was too narrow, and the number of zombies became the target of airship magic guns. Moreover, with the advance of the army on the north bank, the number of zombies on the north bank became less and less. But at this time, the sky was getting dark, and the zombies' home time was coming. At this time, there was another roar of corpses in the center of the city. The zombies on both sides of the bridge retreated like a flood again, leaving only one corpse on the ground.Li Yuanhong knew that at this time, the zombie began to prepare for the night war. After all, human experience was limited. Therefore, the zombie planned to take advantage of people's fatigue at night and easily neglect, so as to seize the weakness of people to attack. But Li Yuanhong will never let the zombie succeed.
