Lu Yunzhou's heart sank, it turned out that Mrs. Lan was Tian Dan's person, this matter may not be as simple as it seems, could it be that Tian Dan established such an underground organization, which will only be used to deal with those secret agents left by various countries, and will not be used in other places?

Qi Ting suddenly realized: "So Mrs. Lan also has people under her, so it's okay for Mrs. Lan to take someone to pick the stronghold of Blood Swallow by herself?"

Qi Fang stretched out a finger, shook it, and said: "Ting'er, Mrs. Lan is the top poison Dao master in the world, she wants to take a small stronghold of Blood Yan in her territory, she doesn't need to bring anyone at all, in a confined space like a secret room and tunnel, she alone can destroy an army!"

Lu Yunzhou smiled bitterly, he thought of the rows of shelves full of poison in Mrs. Lan's underground stone chamber last night, as well as those terrible little animals in the stone altar, and their dismembered corpses on the stone table, and he thought it was true!

“...... It's terrible!It turns out that Mrs. Lan is like this......" Qi Ting's mouth grew in surprise when he heard this, and Qi Fei also covered his mouth in surprise!

Qi Min reminded: "This matter, people who know the inside story are tacit, so you must not tell anyone, do you know?"

Lu Yunzhou and the three of them all looked grim and nodded in agreement.

Qi Jing always looked like he was smiling, and said at this time: "Second brother, you frightened the children, after knowing this kind of thing, Ting'er and Yu'er are afraid that they won't dare to go to Yulan Building to play anymore!"

Lu Yunzhou and Qi Ting's faces turned red when they heard this, and they were a little embarrassed, while Qi Fei suddenly flew his cheeks and sneered: "Uncle, Fei'er is still here!"

Qi Jing smiled and said, "Let's stop standing in the hall, let's start the family meeting as soon as possible!"

When the others heard this, they all agreed, and Lu Yunzhou looked left and right, confused, so he also nodded.

I saw Qi Jing and the others start to walk towards the back hall one after another, and Lu Yunzhou followed them, turned left and right, and walked into a room in the corner of the first floor of Lan Xue Hall.

The room was full of things, obviously a storage room, Qi Ting stepped forward, picked up a big box in the corner and moved it away, Lu Yunzhou saw a trapboard exposed on the ground, Qi Ting turned the trapboard over, and below was a staircase that extended to the ground!

"It turns out that the Qi family also has a secret room, just below this Lanxue Hall!"

It seemed to stimulate Qi Yu's memory in his mind, Lu Yunzhou remembered that there was not only a secret room below, but also some treasures, food and materials that the Qi family had secretly stored, and there was also a tunnel that could directly lead to the Zishui outside the city!

"It seems that this tunnel is the retreat that the Qi family has prepared for themselves!"

Lu Yunzhou looked at the entrance of the tunnel of the black hole, and felt more and more that this was an era of precariousness, and he was afraid that the ownership of this era would leave him a way to retreat! And the people could only sit at home and wait for the heavens to bring blessings and disasters, and once the disaster came, there would be nowhere to hide! Because for the poor people, once they leave their hometowns, they will become displaced people and refugees, and the hope of surviving is too slim!

In this era of war, whether it is a nobleman, a wealthy merchant or a commoner, there is a general lack of one thing - that is, a sense of security!

Lu Yunzhou walked at the end, followed everyone down the tunnel, the tunnel was built very deep, Qi Jing carried a flint on his body, after lighting a torch, the other torches in the tunnel were also lit one after another, Lu Yunzhou found that the soil under his feet was slightly damp, obviously this tunnel was so deep that it was about to dig into the underground river.

On both sides of the tunnel were rows of rooms, all of which were closed and locked, Qi Min took out a key from his arms and opened the door of one of the rooms, Lu Yunzhou followed in, and looked into the room.

This room is not big, there is a long table in the middle of the room, and there are no other superfluous furnishings, to Lu Yunzhou's surprise, on the largest wall in the room, there is a huge curtain, and the curtain is a map of China in this era!

The map clearly depicts the location of the territory of the only nine vassal states and one suzerainty in the land of China, Qin, Zhao, Yan, Han, Wei, Wei, and Zhou. What is surprising is that in the areas other than ten countries on the map, the approximate areas of the border ethnic minorities such as Gaoyi, Donghu, Xiongnu, Linhu, Yuezhi, Heyi, and Baiyue are also marked, and there is one that has been generally forgotten by the countries of this era, located on the Korean Peninsula - Jizi Korea!

Jizi is a famous virtuous minister in the last years of the Shang Dynasty, the uncle of the king of Zhou, was imprisoned by the king of Zhou for outspoken admonition, after the Zhou Dynasty destroyed the Shang Dynasty, Jizi was divided to the Korean Peninsula by the Zhou royal family, and established Jizi Joseon.

Minzi Korea is also the earliest origin of civilization on the Korean Peninsula!

To be precise, the ancestors of the sticks are Chinese!

However, the unscrupulous descendants of later generations, Jin Da Fat, ordered the destruction of the Jizi Mausoleum during his reign! And flatly denied that the Jizi was the ancestor of their sticks! Of course, the family was unfortunate, and such unscrupulous descendants had already been expelled from the house for thousands of years, compared with the vast land and resources of the Central Plains, the Chinese rulers of the previous dynasties also had a barren view of the Korean Peninsula. There is a lack of enthusiasm for a land where birds don't poop - after all, there is not much benefit to being occupied, and it is necessary to spend money and food every year and send people to manage it long distances, so it is enough to just let it exist as a subject. Later generations of Chinese obviously do not want to recognize this group of scum left by their ancestors!

However, Lu Yunzhou's dangerous gaze was already fixed on that small piece of land on the Korean Peninsula.

Just turned over the content of Qi Yu's memory about Jizi Korea, Lu Yunzhou just wanted to pinch off the source of these unscrupulous descendants at this moment!

After several plans flashed in his heart, Lu Yunzhou ignored these and set his sights on the countries on the land of China again.

Of the Seven Heroes of the Warring States, Korea was the smallest, and Korea was divided between Qin and Zhao, a small area west of Huotai Mountain, which was sandwiched between Qin and Zhao, and a small area south of the Yellow River, which was sandwiched between Wei and Qin. However, the territory of Korea, the smallest of the Seven Heroes of the Warring States Period, is also larger than the two small countries of Weiguo and Luguo. In addition, there is a smaller one, which is the suzerainty where Zhou Tianzi is located - the Zhou State. The Zhou State was only left on the map with a piece the size of a fingernail shell, and with such a small land area, it was also divided into two princely states, the Eastern Zhou and the Western Zhou, which were under the rule of the Eastern Zhou and Western Zhou respectively.

Lu Yunzhou looked at the intuitive map, and only then did he deeply feel Zhou Tianzi's grievances!

The largest states marked on the map are the states of Qin and Chu. The state of Chu had already occupied vast areas of land in the southwest and southeast, and the state of Qin was also not smaller than the state of Chu because it had a vast area to the west and south of Ba, Shu, and the south; secondly, because after Li Mu recovered a large area of Donghu and Linhu, the northern territory of Zhao was close to that of the Hetao region, and most of the northeast area was uninhabited. The bitter cold land where birds don't poop is only the Yan State in the south, which is relatively fertile, the Qi State on the edge of the East China Sea, the Wei State in the middle of the Chinese land, the poor Korea where most of the territory is mountainous and is divided into two pieces, the Lu State in the south of the Qi State, the Wei State in the west of the Qi State, and the Zhou State again.

Lu Yunzhou was seriously pondering this map, when he saw Qi Fang suddenly holding a brush, walked to the map, and with a stroke of the pen, he drew out the Shangdang area of Zhao State.

Lu Yunzhou looked at it again and found that the two divided lands of South Korea were connected together!

In this way, the land area of South Korea is about the same size as the land area of Wei!

Qi Fang nodded at the circled area with his hand, and said dissatisfiedly: "Second brother, this map was drawn in the year of the Battle of Changping, it has long been outdated, and it can be replaced, after the Battle of Changping is over, the Shangdang area has long been returned to South Korea!"

Qi Min rubbed his eyebrows and said, "I'm sorry, third brother, I'll let someone draw a new map when it's over!"

Qi Fang smiled and said, "That's fine, it's just the test for three children." Qi Fang looked at Lu Yunzhou and the three of them expectantly, and asked, "Who will tell me, why did Qin Zhao want to fight for the party in the Battle of Changping back then?"

Qi Ting glared and said, "Father, this is too simple!"

Qi Ting walked to the map, pointed to the location of the Shangdang region, and said: "When the three families were divided, the Shangdang region was divided into half of the Zhao State, and the South Korea got half of it, and the Shangdang County of the Zhao State and the Shangdang County of South Korea were adjacent. However, the difference is that the Shangdang County assigned to South Korea has the Taihang Mountain as a strategic screen, which is a strategic point, which can be attacked and retreated, and can be defended, while the Shangdang County of the Zhao State is a plain with no danger to defend! Therefore, once the Han Shangdang is occupied by Qin, the Zhao Shangdang will also be lost, and once the Zhao Shangdang is lost, Jinyang, the important military town of the Zhao State, will be directly exposed in front of the Qin army! Moreover, after the Qin army occupies the Shangdang, it can cross the Taihang Mountain at any time to attack Handan, the capital of the Zhao State, so the Han Shangdang must not fall into the hands of the Qin State, and this is the reason why the Zhao State will seize the Han Shangdang. ”

With a relieved smile on his face, Qi Fang nodded: "Yes, then what is the reason why the Qin State is competing for the party?"

Qi Ting pointed to Anyi, an important military town of Qin located in the west of the Shangdang region, and said: "After Feng Ting handed over Shangdang County to Zhao State, Qin State had to launch the Battle of Changping, just because Zhao State got Shangdang, he could face Qin's Anyi! And once Anyi is lost, Zhao State can bypass the Hangu Pass, which is easy to defend and difficult to attack, cross the Qin Mountains, cross the Yellow River, and directly attack Xianyang, the capital of Qin State, so Qin State will definitely not be able to tolerate Shangdang County in the hands of Zhao State, otherwise King Qin will have trouble sleeping!"

Lu Yunzhou suddenly realized that the battle of Qin and Zhao Changping caused by Zhao State's forcible seizure of Shangdang County in South Korea eventually led to the collapse of Zhao State, and many people in later generations scolded this result because of the greed of King Zhao Xiaocheng and Pingyuan Jun, but in fact, Zhao Guo had no choice at that time!
