Tian Feng was now only concerned about the siege of Lu Bu's army outside the city, but he didn't know that Yuan Xi, who was now on the side, had become distrustful of him.

Moreover, there is also the heart to take him down or tell his father Yuan Shao about the fact that he has defected to the enemy Lu Bu!

If Tian Feng knew, with Tian Feng's upright character, and he did not surrender to Lu Bu, but wholeheartedly wanted to resist Lu Bu's invasion of Youzhou with the army, he would definitely be angry.

Fortunately, Tian Feng doesn't know what Yuan Xi thinks now, otherwise, without Tian Feng, a resourceful man, it will be easier for Tuyin County to be broken by Lu Bu's army!

Tian Feng looked at Lu Bu's army outside the city, and then quickly returned to his normal expression.

No matter how many catapults and fire oil Lu Bu has, now, it is still the first to resist the siege of Lu Bu's army, which seems to be menacing this time.

Then, Tian Feng turned his head and discussed with Yuan Xi on the side about defending the city.

It's just that Yuan Xi, who has already distrusted Tian Feng, is still the same thing whether Yuan Xi, who is the assassin of Youzhou and the chief general of the army in the city, listens to Tian Feng's strategy to defend the city.

……

Outside Tuyin County, Lu Bu didn't know that because of the provocation he had caused when he met Tian Feng before, coupled with the fact that his civil and military forces and soldiers destroyed 10,000 Bohai pirates, and cleaned up Baqi who wanted to make trouble in Xiangping, Liaodong, the current Yuan Xi no longer trusted Tian Feng.

Even if Lu Bu knew the news, he wouldn't care, he would just laugh it off.

In any case, Tuyin County was broken in their siege battle this time.

10,000 catapults were pushed out of the bow and arrow range of the defenders of Tuyin County, and a jar of fire oil was also moved by the soldiers to the side of 10,000 catapults, which could be used at any time.

After the preparations were ready, Lu Bu naturally ordered his soldiers to launch catapults and fire cans of fire oil that had been ignited.

"Boom ......"

"Crackling ......"

Suddenly, cans of fire oil were loaded onto catapults by the soldiers, and they set them on fire.

The soldiers who fired the catapult immediately started to launch the catapult, firing the canister of fire that was burning in the catapult's big spoon.

"Bang ......"

A can of burning oil was launched, shot high, and then smashed heavily on the head of the county town.

Suddenly, the sky was full of burning cans of fire oil, with an extremely hot breath and an aura that could burn everything, and pressed down on the defenders above the head of Tuyin County.

made the Yuan Shao army who was defending the city all stared at each other and trembled.

It can be seen from this that the fire oil canister launched by Lu Bu's army has already dealt a huge blow to Yuan Shao's army before it has attacked them.

It made them all fearful and demoralized.

"Smack......

With the passage of time, under the influence of gravity, the first can of fire oil has successfully smashed on the head of Tuyin County.

Although the first tank of oil did not bring any trauma to Yuan Shao's army, the tank of oil that smashed heavily on the top of the city was very large, like a large water tank.

Such a large water tank shattered at once, and the fire oil in the tank also splashed in all directions, accompanied by the raging fire, so that the fire oil tank was shattered and shrouded in a sea of fire, so that the defenders of Tuyin County did not dare to approach here.

At the same time, the pungent smell of burning fire oil permeated the city, and most of the defenders couldn't stand the pungent smell and were coughing violently!

However, the shattering of the first tank of oil was only the beginning.

As time passed, more and more oil tanks were projected by Lu Bu's army on the head of Tuyin County using catapults.

The oil tank fell from the sky, and then smashed heavily on the head of Tuyin County, and then shattered, and the burning oil in the tank splashed everywhere, so that the entire Tuyin County was soon shrouded in a sea of fire.

There were many defenders on the head of Tuyin County, and some of the defenders who had no time to dodge were splashed with fire oil from the broken fire oil cans, and they tried their best, but they couldn't extinguish them.

Soon, these sad defenders were burned with fire oil and turned into a burning man.

They had not died for a while, and the burning oil on their bodies had brought them great pain.

The pain was so great that they could not bear it anymore and they were scurrying around the city.

Some of the defenders accidentally fell to the high city and smashed heavily on the cold ground, turning into a mess of minced meat, and their deaths were terrifying!

And some of the defenders ran around the top of the city, and ran into the defenders who were not splashed with the oil, and the oil on their bodies got on the bodies of the defenders, and at once set their clothes on fire, causing the defenders to suffer the unjustified calamities of their own companions, and soon they also became burning men.

In this way, most of the defenders who were on the head of Tuyin County turned into burning men, and then, when the oil on their bodies burned out, they also fell to the ground and became a pile of charcoal.

If it weren't for Tian Feng's super decisiveness in the end, he let the defenders who were not splashed by the fire oil shoot those who had become fire men and could not be saved.

Moreover, Tian Feng asked the defenders to dodge the fire oil shot by Lu Bu's army, I am afraid that the defenders of Tuyin County will be burned alive and more people will be burned alive!

……

Outside Tuyin County, Lu Bu, who was directing the soldiers under his tent to project fire oil at Tuyin County, saw this, and Lu Bu's eyes were extremely resolute about the tragic situation of the defenders above the head of Tuyin County, and there was no fluctuation in it, and naturally there was no sympathy at all.

This is a war where either you die or I die, and Lu Bu cannot be allowed to have a trace of women's kindness, otherwise, it will only be his own soldiers who will suffer in the end.

Lu Bu, I don't want this!

Dead and poor people are not as good as dead friends!

If you trade the lives of your loyal soldiers for the lives of the enemy defenders? Heh, Lu Bu is not so stupid! Lu Bu can't wait for the enemy defenders to die early and surpass their lives!

Using 10,000 catapults to project cans of ignited fire oil is so effective in attacking Jiancheng Tuyin County, Lu Bu naturally will not waste this good opportunity in vain.

So, Lu Bu continued to command the soldiers under his tent to project fire oil, so that the defenders above the head of Tuyin County, not far away, turned into burning men one by one.

After the command, Lu Bu, under the protection of Zhou Cang's personal soldiers, together with Chen Gong, the left army division under his tent, watched the enemy defenders who had turned into burning men one by one on the head of Tuyin County rush around the narrow city head!

At the same time, the effect of projecting fire oil was so good, Lu Bu believed that it was only a matter of time before he broke through Jiancheng Tuyin County!

Tuyin County, Lu Bu is broken! Youzhou, Lu Bu is also going to do it!
