As mentioned in the last book, when Dong Erzhu was teaching the owner of the incense shop to take off the aged musk, he happened to see a Bi Fang tail feather in the treasure medicine warehouse of the incense shop.

An alien bird like Bi Fang, a relic of ancient times, may not be able to meet once in decades. Therefore, the probability of this Bi Fang tail feather is nine out of nine is related to Li Chang and his party who were robbed and killed by bandits halfway.

But wasn't the tail feather in Li Chang's hand snatched away by bandits? How did it fall into the hands of the Smelling Fragrance Sect? Could it be that the mastermind behind the robbery and murder of his father back then turned out to be the Smelling Fragrance Sect?!

Dong Erzhu, who felt a chill slowly climbing up his backbone, forcibly suppressed the fear in his heart, and pretended to be calm and smiled flatteringly at the owner of the incense shop: "The owner of the workshop is worthy of being the right-hand man of the sect leader who can't be separated from for a moment, this vision is so extraordinary, admire, admire!" Don't hide it from the owner, the villain urinated and listened to the old man tell the story of the King of Wannu against the gold treasure, but I don't know what this treasure is ......"

In fact, Dong Erzhu's original intention when he mentioned the treasure of the Wannu King was to let the owner of the workshop immediately drive him away under the pretext that 'the treasure of the Wannu King is actually the core secret of the sect, and non-superior disciples are not allowed to hear about it', so as not to accidentally expose his identity in front of him and invite him to kill again.

Who knows, the owner of the shop smiled at himself like no one else: "According to the canon, Niu Wu (Dong Erzhu's pseudonym) is not qualified to know such confidential matters, but who made you our right-hand man?" This treasure of the Ten Thousand Slave Kings is hidden in an abyss called Fallen Heart. ”

According to the owner, the reason why this gorge is called 'Falling Heart' is precisely because in the depths of this valley, there is a star that fell from the sky!

(Note: If there is water at the bottom of the valley, it is called the abyss, and if there is no water, it is the gorge)

As for when this star fell from the sky, no one knows, anyway, since the hunters who hunted in the mountains and forests discovered this abyssal valley, the spherical meteorite with a diameter of more than ten zhang was attached to the mountain wall on the side of the abyssal valley, lying quietly in a black quagmire with a circle of hundreds of zhang.

At first glance, when he heard the words 'black quagmire', Dong Erzhu couldn't help but exclaim: "Protecting the treasure black spring? The venom of the hundred-legged dragon? ”

However, the owner pointed at Dong Erzhu with his finger and laughed "haha": "Niu Wu of a good village!" You don't want to think about it, how many hundred-legged dragons have to fill up with the venom of the hundred-legged dragon in the radius of hundreds of zhang in that black pool? Besides, Puxian Wannu hid the treasure at the end of the Jin Dynasty and the beginning of the Yuan Dynasty, and more than 500 years have passed, and the sun alone is enough to dry the venom poured back then. ”

The owner told Dong Erzhu that this black quagmire with a radius of 100 zhang was indeed the legendary black spring that surrounded the treasure.

However, this black spring is only a puddle of rainwater that collects here, and although it cannot be drunk, it is not toxic to decay and decay.

What can really protect the treasure is actually a group of hundred-legged dragons living in the mud pit of the black pool!

According to legend, the Puxian Wannu who buried the treasure was originally from a small tribe with a population of less than 5,000.

If such a small tribe can firmly occupy a mountain forest for its own survival, then there must be something extraordinary behind it.

Don't sell it, this small tribe from Puxian Wannu is especially good at capturing and domesticating a hundred-legged dragon, a large centipede with a body length of more than two zhang and a highly poisonous body!

And the medicine arrow fed with the venom of the hundred-legged dragon is the magic weapon of this small tribe to defeat the enemy.

Anyone who is scratched a little bit by the medicine arrow, the venom fed on the arrow will spread all over the person's body with the blood flow, so that the arrow wound will never be able to heal, and the person will be hurt to death!

Although the effect of this medicine arrow is vicious and domineering, its production is a big problem.

Only the fresh venom just collected from the hundred-legged dragon has this miraculous effect of seeing blood and eroding flesh, and once it has been separated for a long time, it has to be fed twice, otherwise it will not have any effect at all.

Therefore, the Puxian Wannu clan can only keep five or six hundred medicine arrows in their hands for a long time, and if they prepare more, the venom of the hundred-legged dragon will not be supplied.

Under the flood of Mongol attacks, the Puxian Wannu clan quickly exhausted all the medicine arrows in the clan, and then collapsed under the iron hooves of the Mongol cavalry.

At the last moment, Puxian Wannu took the few hundred remaining soldiers and carried the treasures he had looted from the treasury of the Jin Kingdom, and retreated into the 'Fallen Heart Abyss Valley' in a desperate way.

The Mongolian pursuers who followed quickly surrounded the 'Fallen Heart Abyss Valley', but they never expected that in addition to dozens of boxes of gold and silver treasures, Puxian Wannu also brought five more pairs of male and female hundred-legged dragons!

"Niu Wu, you don't know, the 'Falling Heart Abyss Valley' is several twenty zhang deep, and the abyss valley is no less than twenty miles from mouth to end, but it is extremely narrow! The widest is less than three zhang, and its narrow place is often only more than zhang. ”

In the face of such a narrow valley, the Mongol pursuers had tens of thousands of troops, but they could not set up a formation at all, they could only put on a long snake formation, and ordered a group of ten people, holding spears and advancing side by side, so that they could fight into the valley in rows.

However, to the surprise of the Mongols, although Pu Xian Wannu's own soldiers were no match for the well-trained Mongol army, the hundred-legged dragon he brought into the valley was a murderous killer!

These giant centipedes can walk like flying on the rock wall, and they are not afraid of the Mongols' arrows with thick scale armor!

These centipedes often swept past the vanguard of the Mongol army from the high rock wall in a single face, and then leaped between the unsuspecting soldiers in the center of the array, opening their hideous mouthparts and gnawing wildly.

Attacked by the hundred-legged dragon, these soldiers, who had no room to turn around and flee in the narrow valley, and could not raise their spears to resist, suddenly turned pale and cried out in terror.

After the army withdrew from the valley again, and counted the soldiers, this army, which had more than 10,000 people in front of the station, lost more than 3,000 people at once!

The Mongol general, who suffered a crushing defeat, first frowned, and then ordered his soldiers to carry the earth and dig a trench, build a high wall at the mouth of the deep valley, and fight to trap Puxian Wannu for life and death!

In this way, the Puxian Wannu army, which had just won a great victory, suddenly fell into a dangerous situation of sitting and waiting to die.

Unlike humans, who can chew leaves to satisfy their hunger, giant centipedes cannot leave blood food for a moment. Soon, these hungry hundred-legged dragons stared at a pair of blood-red compound eyes, and viciously pounced on Pu Xian Wannu's own soldiers and sucked them.

Although all of these soldiers swore to be loyal to Puxian Wannu and would rather be fooled than betrayed, 'being beheaded by the enemy on the battlefield' and 'turning into a puddle of humanoid pus and blood under the mouth of a centipede' are by no means the same way to die.

Under great mental pressure, some of the pro-soldiers rebelled against Puxian Wannu, and while he was asleep, he tied him firmly with ropes and pushed and shoved them to the Mongol army stationed outside the deep valley.

Knowing that the Mongols would hate him, Puxian Wannu, who would not escape death even if he surrendered immediately, flatly refused the Mongol general's order to try to drive away the hundred-legged dragon in the deep valley.

The thunderous Mongol general immediately ordered the slaughter of Puxian Wannu, and at the same time forced the surrendered soldiers to enter the valley again to drive away the hundred-legged dragon.

However, this time, the hundred-legged dragon, which had feasted on human flesh and blood, was no longer tamed, and as soon as it saw the trembling soldiers holding the insect repellent cakes, they pounced on them with red eyes.

The Mongol general, who found that even if he cut off his head and cut it in half, he could not force the surrendered troops to enter the valley again, and finally could only give an order to completely block the Falling Heart Abyss Valley with rolling wood and earth, and then took the head of Puxian Wannu and hundreds of surrendered soldiers, and looked for Wokotai to return to his life in despair.
