No matter whether the master of Mu Kingdom has any stratagem or not, he has to put it aside first. The most important thing at this time is to take Murong city and trap the imperial palace!

Zikun hands a Yang, "attack!"

Under the frenzied percussion of the drum beating wind, the continuous and dense drum sound, which symbolizes the dispatch of troops, rings outside Murong city. The rolling stones on the stone throwing machine are launched one after another. With the precise adjustment of the control hand, the big stones of the millstone are accurately smashed towards the guards on the city wall.

At the same time, the vanguard troops of Beilan Kingdom rushed towards the wall of Murong City, and the city climbing ladders that had been prepared for a long time were set up on the wall one by one. With the flying out of the cornice rope, the vanguard's elite soldiers were like rats smeared with oil under their feet, climbing up quickly.

On the other side of Murong City, people were killed and injured when they were hit by stones, and the soldiers guarding the city wall immediately panicked.

"Don't panic! At the command of our general, let out tung oil! "

The attack of Beilan country is swift and violent, but Murong city is not embroidered pillow.

The commandos of Beilan kingdom are fast, and the general of Murong city gives orders faster. With a single order, the big barrels of tung oil are fallen from the wall by the soldiers.

All of a sudden, several commandos of Beilan Kingdom failed to grasp the ladder and rope. They fell down and fell to the ground heavily. They were drowned in tung oil.

It's not the most important thing to fall down because of tung oil. The most terrible thing is that the black tung oil is sticky and slippery, so it's hard to remove it.

As soon as the barrels of tung oil were poured down, it was like a tung oil waterfall. Many soldiers of Beilan kingdom had their mouths and noses stained with tung oil. They couldn't get rid of it. As a result, they had difficulty breathing. They yelled at each other and looked terrible.

Zikun frowned.

It's easy to defend a city, but it's hard to attack it. What's more, Murong City, the last line of defense, even if it has only 20000 elite soldiers, but with this turtle shell like wall defense, it's really difficult to break it.

Seeing tung oil flowing all over the ground at the foot of Murong City, zikun waved his hand, the commandos who had previously started the battle began to retreat. A large number of blasters and elite soldiers who were responsible for hitting the city gate showed up, bypassed the tung oil and rushed to the weakest city gate of Murong city wall!

Tung oil is flammable and the city wall is insulated. The garrison generals of Murong City pour tung oil down so cheaply. It's obvious that they want to use tung oil to wash down the soldiers who climb the city wall first. Once they dare to continue to try to climb, as long as they ignite the tung oil under the city wall, they can let the soldiers of Beilan Kingdom burn themselves.

This move is a common way to defend the city. Zikun had expected it, so what he prepared was also a special way to deal with tung oil!

If tung oil burns, it will be isolated from the outside of Murong city because of the city wall. But if fireworks and firecrackers are used before the soldiers ignite tung oil in Murong City, and nitrates and sulfur are mixed in them to make a simple modified explosion bamboo tube, which is put under the stone wall of Murong city. Once tung oil is ignited, the bamboo tube will also explode, which will blow out a gap in the city wall!

Explosion bamboo tube, is a kind of mining things, not common, appearance and fireworks are the same, encounter high temperature will explode.

The only difference is,
