Lin Mu then continued to embark on the long road, and there were low roars around him from time to time, and there were some sweet temptation sounds, all of which were ignored by Lin Mu.

Eventually, Lin Mu came to a rushing river, and the river was full of resentful spirits twisting and moaning, making people's scalps tingle.

And in front of the river there is also a huge stone monument with some strange words engraved on it.

When Lin Mu was studying the meaning of the words above, he heard a prompt from the system:

"Host, the text above means that the water in this river is weak water in the underworld, and the suction power is extremely large, and no matter how vast the supernatural power is, once it touches a trace of weak water, even the gods will be difficult to save.

And the way to cross this river safely is to build a bridge through one's own merits, but if a person is born with many unrighteous and evil deeds, his bridge will be fragile.

Once the bridge of merit is broken, the people above it will surely fall into the weak water, and they will be accompanied by resentful spirits for eternity. ”

After hearing this, Lin Mu said confidently: "Then there should be no problem with this level, my current merit value is also about 40,000, if even I can't build a qualified bridge, then there will be no one to break the formation after this Heavenly Dao mutation." ”

"Having said that, why are you willing to remind me today, even if it is an important thing on weekdays, you are often willing to say it in secrecy." Lin Mu asked curiously.

"Because the system needs to hand over the next thing to the host to do, the next thing, the system will go through to provide assistance to the host." The system says.

"Huh? What's going on, if you usually have a task, you can just post it to me, why do you have to make it so strange now? Lin Mu asked in surprise.

"The previous missions were all set up to help the host reach the ultimate goal and become stronger. However, this mission is to hope that the host can help the system to complete and work hard. The system then said:

"At the beginning, because of some accidents, the merit system had some accidents, and then it was greatly weakened, so it was immediately after the appearance of this time and space to find a host, and even the excess energy to expand the search area was difficult to spend.

Although the system has recovered some of its capabilities due to the host's recent efforts and the system's self-healing, it is still lacking a lot from the period of disruption. And this celestial prophecy was made by stealing the heavenly machine from the peerless alien method in the human world, and it contains a great Heavenly Dao origin, which also angered the Heavenly Dao and caused an extremely terrifying mutation here.

If the host can master the Heavenly Secret for the system, and then master it for more than an hour, the system will be able to obtain this part of the origin. As for the host's reward, it is a further permission. The system said.

But Lin Mu was eager to try, originally he came here to obtain the Heavenly Secret, just to let the system absorb the origin by the way, but the content of the prediction has already been written on it, there will be no loss, and he can also have further permissions by the way, why not. After all, the opening of the permission of the last system upgrade allowed Lin Mu to use the Shimen system, and I don't know what rewards will be given for the opening of the permission this time.

Just as Lin Mu was preparing to condense merit as a bridge according to the method mentioned in the inscription, and then forcibly cross the river. From a distance, a black shadow floated leisurely, slowly stopping in front of Lin Mu's eyes.

"Young man, do you want to cross the river?" The strange voices of men, women, and children came from the dark shadows in front of them.

"yes, I'm getting ready to cross the river." Lin Mu said vigilantly.

"So do you know what is written on this stele? As long as you are willing to exchange your most precious treasure with me, I will translate the method of crossing the river recorded on this stone tablet for you. The dark shadow said.

"The most precious treasure? I don't have any treasure on me. Lin Mu wondered.

"As long as you are willing to sell your soul, let me translate the text for you."

Lin Mu was about to speak, but he heard the system say: "Host, this is the product of the evil ghosts detained in the formation after the mutation, if you agree to him, even if you sign the Heavenly Dao contract, you will be completely controlled by him." At present, the most suitable method for you is to use pure yang true qi to completely disperse him, otherwise he will destroy the merit bridge while you cross the river. ”

Only then did Lin Mu understand the origin of the other party, this should be the gatekeeper set up at this level, and after meeting his requirements, he would tell the person who broke into the battle what was written on the inscription. But now this gatekeeper is insatiable and wants to murder Lin Mu, so Lin Mu can only strike first.

"Selling your soul?" Lin Mu said, but suddenly trembled, his eyes were stunned, and he looked directly at the back of the black shadow.

And the black shadow also turned around in surprise, but it was directly blasted away by a punch full of Gangyang's internal force, and then fell to the side.

"You can't kill me, otherwise you will be trapped here forever, this inscription is except for me" The evil ghost said in a panic, but before he finished speaking, he saw Lin Mu smiling and pulling out a part of the golden light from his body, and then with a flick of his hand, it turned into a golden bridge.

"How do you know" The originally illusory shadow also dissipated and completely disappeared into the air.

After Lin Mu repeatedly made sure that the other party had completely dissipated, he walked on the Golden Bridge of Merit.

The ghost wind roared below, but standing on top of the golden bridge was as steady as Mount Tai, and the sturdy golden bridge blocked all the ghosts who tried to climb towards the golden bridge.

"Host, there are too many resentful spirits in this river, please cross the bridge as soon as possible, otherwise the golden bridge will collapse." The system reminded.

Lin Mu came to the other side of the river after only a few moments on the bridge, and then the golden bridge also turned into a golden light and melted back into Lin Mu's body.

Immediately, a figure of a fairy wind dao bone also appeared on the opposite side.

"I didn't expect Lin Mu Xiaoyou to be really talented and extraordinary. He was able to pass all the difficulties in such a short period of time and successfully reached the core of this formation. It was Jiang Chen, who was waiting here, who said with a smile.

"But Jiang seniors haven't been waiting for me here for a long time, in terms of temperament, I'm still far from my predecessors." Lin Mu was also modest.

"This is not true, the old man was able to come here so quickly, just because the old man was familiar with the yin and yang formation, and he broke the formation. But the little brother has a clear conscience and is above board, so he can naturally not be disturbed by the maze here. Jiang Chen turned around, and then pointed to a circular formation.

"This is the core of this formation, you and I enter the formation together, if we can pass the trial, we can lift the killing array here, not only can we rescue the unconscious people, but also get the heavenly machine safely."

Lin Mu immediately stood on the side of the formation like Jiang Chen, and then instantly entered the core of the formation.
