When they realized that it was fire oil, they immediately thought of the enemy's purpose of projecting such a large amount of fire oil on the battlefield, so the desperate screams of foreigners rang out one after another on the battlefield: "Oh! no-"

But Zhou Yu didn't have any mercy on his subordinates, and continued to order: "Release the rocket-" Then I saw that the heavy arrows on the ballista were also replaced by rockets tied with sackcloth dipped in fire oil, flying like fire dragons towards the coalition forces of various countries that had begun to panic!

As soon as those fire dragons landed, the fire spread rapidly, and the battlefield sprinkled with fire oil became a hell on earth in the blink of an eye, and those wooden siege equipment had no chance of surviving, and were quickly burned to ashes, as for those foreign players, they don't really feel the feeling of being roasted by fire like NPCs, in addition to feeling the heat, they will only see their health drop rapidly, and then turn into a white light and disappear on the battlefield.

Since there was an open space around the base, there were no other combustible materials except for the equipment advanced by the enemy, so the fire came and went quickly, and in less than ten minutes, except for those catapults and columbs and other equipment were still burning, the fire in the rest of the place was all extinguished.

But it was in less than ten minutes that the first wave of attack troops sent out by the coalition forces was completely annihilated, and the losses totaling millions of men in the four directions were secondary, and the loss of those siege equipment was definitely a heavy blow to the coalition forces: except for the ballista that was spared due to the long distance, the loss of the rest of the catapults, covets, and rushing carts was at least equivalent to ten days of production in their base! That's one-third of the original total!

Of course, although this loss is very heavy for the coalition army, it can also bear it, but with the lesson of this time, before it is determined that the Yunze army has run out of fire, they will never dare to engage in positional warfare with the Yunze army again, for fear that the Yunze army will take advantage of their gathering time to drop this kind of big killing weapon again.

The inability to engage in positional warfare does not mean that the coalition forces will stop attacking the base, and they have finally gathered together again, and if they cannot recapture the base while the civilians have no time to take care of it, the alliance they have just formed may be dissolved on the spot.

As long as there is a little slackness anywhere in the Yunze army, they will gather their forces to break through from this place, and once the Yunze army reacts and begins to concentrate their forces to counterattack, they will immediately retreat, so as to force the defenders to maintain a nervous state at all times and distract the defenders.

At the same time, they were also inspired by Yun Zejun, knowing that fire oil, a daily necessities that can be found everywhere in the grocery store, can play such a huge role on the battlefield, so they also began to collect fire oil everywhere in their respective game areas. Especially some countries in the Middle East, after they saw the power of Yunze munition oil, they immediately thought of their own specialty - oil, it is said that as early as the time of the Babylonian people, the people there have used oil as a weapon, this thing is much better than fire oil, once contaminated, it is like a dog skin plaster is difficult to get rid of, and it is very resistant to burning, and the impurities in it can also produce toxic gases when burning, even if you can't burn you to death, you can be poisoned!

When the forces of so many regions and so many countries are all in operation, the energy generated is not comparable to that of a lonely person like Wenmin: in less than a day, they have collected a large amount of thermal oil, especially the Middle Eastern countries, which have contributed countless amounts of oil to the coalition forces, and there are continuous follow-up supplements, so now if the coalition forces want to use fire attack, it can almost be said that there is an inexhaustible supply of thermal oil and oil.

This is not enough, how to put these oil and oil on the city wall is the most critical problem, it is definitely not possible to directly use catapults to smash them with catapults like Yun Zejun, because their range is not as good as others, if they do this, they will be buried in the fire again before they get close, and the fire oil they carry has no other effect except to burn themselves more fiercely.

Of course, the commanders in the coalition forces were not all wine bags and rice bags, and they quickly came up with a solution: Aren't you able to give us a range advantage because of the height of the walls? We won't be able to build a wall in a short period of time, but it's okay to get a mound of earth out of it, right? Wouldn't it be possible to overtake the defenders' advantage by raising the mound of earth beyond the range of the defenders' catapults? Although this is also a huge project, the coalition forces are too crowded, so it is no problem to concentrate a sufficient number of mounds in one direction, right?

Just do it, with the order of the coalition command, the players of the coalition army all took action, although they don't have any modern tools, but because it's in the game, people don't feel tired at all, and the characters in the game are much stronger than in reality, even if everyone carries one or two hundred catties with their bare hands, it's not a problem at all, with the passage of time, mounds of earth rise from the ground, and it won't be long before their height catches up with or even exceeds the height of the city wall, At that time, the only advantage of defending the city that the defending Yun Ze army relied on will no longer exist, and they will fall into a situation of being passively beaten.

At the beginning of the coalition army's operation, Zhou Yu guessed their plans, but there was no anxious look on his face, and he had a completely confident expression, but when someone asked him what he should do, he just smiled and asked them to wait and see.

On the third day of the Coalition attack, they had finally built a mound of earth large enough to hold a certain number of catapults and ballistas, and after nearly forty hours of hard work, they had finally completed the massive project! I saw that in the east of the No. 1 base of the National War, there were dense mounds of earth one after another, and some were even connected to form a wide platform.

Because there was plenty of space outside the city, the mounds formed a strip about ten kilometers long and more than a hundred meters wide, and there was ten times as much space for catapults or ballistas as on the city walls! At that time, if the two sides carry out long-range equipment bombardment, they can crush the Yunze army on the city wall in terms of number and range, and at this time, it is no less difficult for the Yunze army to destroy these platforms than it is to capture a strong city, which is almost an impossible task for the defenders who are far from the number of the coalition forces.

Looking at the platform that has been successfully stacked, the leaders of the coalition forces up to the headquarters and the ordinary players are all excited, and Davis said proudly to the other leaders: "I heard that there is an idiom in China called 'one force down ten benefits', although our method is a little stupid, but it is obviously the most effective." I really can't think of any other way to break our 'fence tactics', I guess the Chinese commander on the other side is already dead, right? Hahaha......"

Franz also excitedly chimed in: "Davis is right! And I heard that the commander is still a god-level NPC, haha, in my opinion, those NPCs are NPCs, even if they are god-level, they are only played by us, come, let's celebrate in advance! ”

"Everyone, let's not be busy celebrating yet, let's quickly organize people to transport the equipment to the platform and start attacking, I can't wait to see the helpless appearance of the enemy in the base!" Barmara interrupted them and urged.

So at the urging of the coalition command, the coalition forces were busy transporting those catapults and ballistas to the platform, but this time the main ones on the platform were ballistas, because their "fence" was built outside the range of the ballista in the city, and even if their platform surpassed the defenders in height, it was not enough for the catapults to attack the city wall, and the main purpose of placing the catapults now was to prevent the Yunze army from rushing out.

Their plan was to use the ballista to kill the defenders' defensive equipment on the wall first, and without the equipment to defend the wall, even if it was as strong as it was, it could only be reduced to the point of being ravaged by others.
