Listening to the words of the system, Tang Seng thought for a while.

10,000 merit points can only be used once, in fact, it is really a loss, but this is also the price paid to complete the task, with 10,000 merit points to exchange, 300,000 merit points, no matter how you say it, it is also earned.

Therefore, Tang Seng did not hesitate at all, and redeemed the one-time experience card in the system.

Then the light flashed, and a small spherical thing appeared in his hand, Tang Seng felt in his heart, he had now completely refined the water shelter in his hand.

As soon as Tang Seng's mind moved, this small round ball quickly became larger, becoming the size of a person, completely covering Tang Seng, and then the expanded shield suddenly became the same as Tang Seng, the size was attached to his skin, and it was hidden and invisible.

Tang Seng moved a little, and found that this water shelter cover was on his body, which did not affect his movements and mana at all, Tang Seng nodded, very satisfied.

After using the water shelter, Tang Seng didn't think much about it, and jumped directly into the Tongtian River.

This Tongtian River is formed by weak water, and there is no trace of buoyancy at all, so after Tang Seng fell into it, he sank directly to the bottom of the river.

This Tongtian River is not only very wide, not in sight, but also very deep, Tang Seng fell into it and couldn't see the bottom at all.

The further down he fell, the less light Tang Seng could see, and the surroundings became very blurry.

Tang Seng frowned slightly, and then used his mana on his eyes to improve his eyesight, so that he could see the things around him clearly.

Seeing that he had not yet landed, Tang Seng no longer waited for silence, but used his mana to swim himself forward.

Although Tang Seng can't swim, with the support of mana, he can be regarded as a person who can move freely in the water.

Tang Seng swam forward for a while, and suddenly he found that the black shadow in front of him flashed and flew towards his right side, Tang Seng immediately turned around and chased after the black shadow.

After chasing for nearly half an hour, Tang Seng found that his eyes suddenly lit up.

Not far ahead, there is a glittering palace perched on a hill.

There are not many mountains in this water, but this one in front of Tang Seng is endless, and there is no end in sight.

The black shadow went straight towards the bow and arrow, and Tang Seng did stop.

Because he saw that there were strict guards outside the palace, countless monsters covered in black fog were patrolling around vigilantly, guarding Tang Seng to the death, just by looking over, he saw thirty or forty guards.

And this is still a guard on the bright side, and the garrison strength on the bright side is so high, there must be more secret agents in the dark.

Tang Seng was a little puzzled in his heart, what the hell is going on? A small palace, although it is said to be a little luxurious, but it is not as good as the Dragon Palace of the Dragon King of the Four Seas, just this palace, the power of the hand is even stronger than the Dragon Palace.

Tang Seng secretly thought in his heart that his mission was to explore the truth of the black fog, and it was estimated that he would be connected to this palace.

Tang Seng thought for a moment, he was thinking about how to sneak in, after all, there didn't look the slightest strange outside of this palace, and only when he went inside could he know the secret.

Tang Seng found a hiding place and hid behind to observe carefully.

He spotted the guards outside the palace, a team of five people, patrolling around. Each group has a fixed observation spot, and when they turn around on patrol, they will definitely show blind spots that they can't see.

This dead end is Tang Seng's chance, and it is also the only chance for him to sneak in without being discovered.

Tang Seng observed for nearly a quarter of an hour, and he found the law of the direction of these people's patrols, and he also found a direction that would not be seen, but the problem was that this lasted only about two seconds, and once Tang Seng couldn't rush over within two seconds, he would definitely be discovered.

In addition to this, there is another thing to pay attention to, that is, whether the surrounding spies will notice this dead end, this is also a problem, so Tang Seng immediately put his eyes on the relatively hidden places around, wanting to find the location of those spies.

Sure enough, under Tang Seng's careful search, he found that there were people hiding behind several corners of the palace, and there were also some people hiding on some terrain outside the palace and observing carefully.

Tang Seng measured carefully for a while, and he found that there was only one person who could see that blind spot, and this person was very far away from the other secret agents.

Tang Seng immediately came up with a way to kill this spy and then sneak in.

Just do it when you think of it, Tang Seng didn't hesitate at all, and the whole person crawled towards the secret agent.

Because the shelter around him is very small, he will not be seen until he is lying down.

Tang Seng quietly climbed behind the spy, then stopped, waited for a while, and found that the spy did not notice a person behind him in the slightest.

Tang Seng slowly stood up, and then took out the Ninety-Nine Scattered Gourd from his hand.

Pouring mana into the red gourd, the red spiritual mud and sand suddenly erupted. It quickly fell on the spy with lightning speed, completely controlling his spirit, making him unable to move in place, and not even leaving him a chance to open his mouth to call for help.

Then Tang Seng pounced and solved the guard at once.

After the guard died, Tang Seng did not act rashly, but stayed where he was and waited for a while.

This is because Tang Seng is afraid that there will be some way for these spies to communicate with each other, and when Tang Seng kills him, he will be discovered by others, but fortunately he has waited for a long time, and there is nothing unusual in this palace.

At this moment, Tang Seng completely relieved his heart.

He then rummaged through his system space and pulled out a Fulu card.

This is the magic talisman he extorted from Tai Bai Xing when he was in the Guanyin Zen Monastery before.

He hadn't had the opportunity to use it before, so he saved it, and now that he needed something to increase his speed, he remembered the spell

Tang Seng poured mana into the spell. The spell suddenly shattered, and countless dots merged into Tang Seng's feet.

Tang Seng instantly felt that his body was lighter, and his feet became very powerful.

Of course, all this is just Tang Seng's illusion, this happiness does not only work when running, he can increase his speed in the process of any movement.

The corners of Tang Seng's mouth hooked into a smile, and he quickly climbed back to Fang Cai's position, and then the whole person squatted forward.

His eyes were fixed on the location of the blind spot, at the patrol, and then counted down in his mind.

Three

Two

One

At the moment when he counted to zero, Tang Seng rushed forward and ran straight towards the dead end.
