Hearing Cao Youyi's analysis, long Tianci and Ge ye both nodded and said they had noticed it. In particular, the four cities attacked later became more and more difficult, and the soldiers in the city seemed crazy. Although the desperate defense of this small city may not be able to stop them, it increased unnecessary losses to the army, In the four sieges, the dungeon army was killed and injured more than fifteen thousand. If it is consumed, the gain is not worth the loss!

The reason why Cao Youyi stopped the army was to find a way to stop the city masters of the next two cities from fighting desperately. There is only one way to achieve this goal, that is, to let the city masters not under the control of the supervisor!

Therefore, they have to find a way to contact the city Lord and save the city Lord's family from the hands of the supervising general. Therefore, the three have formulated a series of plans. Long Tianci personally led some powerful men to sneak into the city late at night to contact the city Lord!

Unfortunately, what they thought was too simple. Perhaps it was because they realized that they could not defend the city with the strength of the city. The supervisor in the city asked the city master to abandon the city and take the whole city's soldiers and people to the last boundary pillar city for joint defense. In this way, the strength of the two cities should increase the strength of guarding the city. Moreover, the boundary pillar city was reconstructed from the border fortress a long time ago, Recently, it has been repaired. Today's boundary pillar city is a strong city that is easy to defend and difficult to attack!

The city Lord did not dare to disobey the supervisor's order. He could only lead the people and soldiers of the whole city to leave the city under his jurisdiction, retreat to the boundary pillar City, and burn the city with a fire when he left!

Well, the plans of long Tianci and others have completely failed. Although a siege has been avoided, the final boundary pillar city has also increased its strong strength. If it was attacked in the past, the loss will be great!

The dungeon army bypassed the burning city and came to the outside of the boundary pillar city and camped five miles outside the city. Long Tianci and others also came to the boundary pillar city at that time. At that time, the boundary pillar city wall was broken and the city gate collapsed. It looked like a dilapidated look, but now the boundary pillar city has high walls and thick gates. From a distance, there are still many people shaking on the wall, It's obviously strengthening the city wall!

This city is completely different from the previous 15 cities. The city is high and thick, easy to defend and difficult to attack. In addition, there are 30000 garrisons in two cities in the city. If the war starts, it will not end in a moment and a half!

According to the analysis of long Tianci and others, it is impossible to attack this city for ten days and a half months. At this time, a message came to the ears of long Tianci and others. The green dragon Empire and the rosefinch Empire have sent troops. Although the army of the rosefinch empire is still at sea, the army of the green dragon Empire has landed, Fortunately, the army of the Qinglong Empire didn't come to help immediately after landing. It seems that they acted together after the army of the rosefinch Empire arrived.

This time, the two empires, the green dragon and the rosefinch, sent a total of 200000 people. If you count the remaining 200000 people in the Imperial Army, the total is nearly 500000, while the dungeon army is only 300000. This time, they are attacking and the enemy is defending. Their roles have changed. They are not as many as each other. How should we fight this battle?

For the present, there is only one way, that is, to end the war before the arrival of the rosefinch Empire, so that the two empires of rosefinch and Qinglong will no longer have an excuse to intervene.

But let alone capture the imperial capital now, even if the boundary pillar city in front of them may not be able to attack in a short time. How can they end the war as soon as possible?

The three marshals discussed again for a long time and finally decided to implement the previous plan. A few elite led by long Tianci sneaked into the city to contact the city Lord. As long as they can persuade the city Lord to surrender, things will be easy to do!

Late that night, long Tianci changed his night clothes and took five carefully selected elites to dive towards the boundary pillar city. He came to the bottom of the city wall. Long Tianci and others stayed for a period of time. After the patrol soldiers on the city wall walked away, they took out the grab hook to hook the wall pier and climbed up!

Perhaps because of the impending war, the whole boundary pillar city is dead. You can't hear anything except the footsteps of soldiers on the wall. Except for some light in the city master's house, other buildings in the city are dark.

After observing the surrounding situation, long Tianci took the people down the wall. Who would have thought that they saw a terrible scene under the wall. An open space in the southwest corner of the inner side of the wall was filled with entities. From the perspective of their clothes, these entities should be the people in the city. These hundred surnames are ragged, skinny and have many scars on their bodies, It is estimated that he was forced to help repair the city wall and died of fatigue.

Although it's amazing to see so many dead people, long Tianci and others have no time to delay. The dark environment in the city creates very favorable conditions for them. They sneak towards the city master's house without making any sound!

I don't know if it's because the army pressed the border that the soldiers in the city paid attention to the army that became the underground city. There were no soldiers patrolling the night in the city. Long Tianci and others came outside the city master's house almost without fear and danger!

However, the silence of the city Lord's residence is completely opposite to that of the surrounding area. Before, the light of the city Lord's residence was not very bright from a distance. However, it would be silly to see long Tianci and others close. The city Lord's residence is full of Liangzi Pinus tabulaeformis. The lights illuminate the city Lord's residence within a radius of nearly 1000 square meters. Let alone individuals, even a fly will be seen!

The city Lord's residence is surrounded by soldiers. These soldiers are tall and burly in black armor. Their weapons are not the standard spear and machete of ordinary soldiers, but a huge double-edged axe!

So many soldiers are guarding the city master's residence. It's not easy for long Tianci to enter. Just when long Tianci was in trouble, he suddenly saw two soldiers in city guard uniforms coming out of the city master's residence with a wind lamp in his hand. Long Tianci looked at the two soldiers through the light, and then smiled, Because the two soldiers were bald and Scarface who came to boundary pillar city with them, it seems that these two guys joined the city guard.

As soon as he saw the two men, long Tianci smiled, and then ordered his men to wait in place and quietly follow the two guys towards the dark!

After a distance from the city Lord's residence, long Tianci suddenly ran out and blocked their way. When they saw a dark shadow suddenly blocking their way, they were startled. The bald man even took out a machete from his waist and cut it off at long Tianci!

How could long Tianci be cut by a bald man? Just as the bald man waved off his machete, long Tianci sidestepped away from the machete, then raised his right hand and slightly bent his fingers, and then played on the blade face of the machete. With the action of long Tianci, the thick backed machete was suddenly broken by long Tianci.
