Black Forest Strike, my light speed ship was exposed

Li Mu was helpless. He had no hope for this research. If he hadn't listened to the system's tricks, he would have changed his direction long ago.

Soon, Li Mu returned to his research room with the materials he had just collected.

He began to continue the research that had failed three times before.

In the laboratory, Li Mu carefully melted the black stone into a pool of liquid using the Empire's technology, and then reshaped it.

According to the guidance of the system, the shaped material was carefully installed on his flying sword.

"This time, I must succeed. If I fail again, my flying sword will probably break!"

Li Mu prayed secretly in his heart. Finally, when the last step was completed, Li Mu's face showed a hint of excitement.

Because this time it didn't explode directly after all the processes were completed like before,

"Success! I finally succeeded."

Three times, three full failures, have worn out all of Li Mu's patience, but this fourth time he unexpectedly succeeded.

Looking at the flying sword emitting a faint white light, Li Mu couldn't wait to pick it up 370.

He could feel that the power contained in this flying sword now far exceeded that of the past.

Even the spikes formed after decomposition and reorganization were more powerful than before,

The most important thing is that this flying sword has a new function.

The flying sword began to reorganize in Li Mu's hand, and the next second his arm was covered by a giant cannon.

This is the second mentality of this flying sword.

This giant cannon looks huge, but it has no weight in Li Mu's hand and can be lifted easily by him.

And its power is also very impressive, otherwise Li Mu would not have spent so much effort to upgrade this flying sword.

"According to the description of the system, the giant cannon that this flying sword turns into after upgrading is extremely powerful, and it can even kill a Jindan Zhenren with one shot. I don't know whether it is true or not."

"It's a pity that there are no experimental subjects at the moment, otherwise I really want to try the power of this giant cannon to see if it is as strong as the system says."

A gleam flashed in Li Mu's eyes, and then he changed the giant cannon back to the form of a flying sword.

Speaking of which, he has been here for three years, and it's time to go out and travel.

However, before leaving, he still has to settle the orphans he adopted. After all, these children are the sparks of his future development of science and technology.

Thinking of this, Li Mu did not hesitate and directly summoned the orphans.

And he gave them all the scientific and technological knowledge he had just sorted out.

"You are all my most proud students. These are the knowledge that I have sorted out specifically for you. You must study hard during the time when I am away. Remember not to slack off."

"By the way, don't forget our purpose. Everything should be kept low-key. No matter what, you can't act on impulse, especially forWhen the master is not here!"

During these three years, Li Mu has always adhered to the principle of keeping a low profile and developing steadily.

At the same time, he did not forget to teach these truths to his disciples.

After three years of teaching, those orphans have all learned the true teachings of Li Mu.

Never cause trouble, there is no way, now Li Mu's technology has just started.

It is far from being strong enough to confront the entire cultivation world.

However, Li Mu believes that sooner or later, the technology he spreads will definitely have a place in this world.

Three days later, Li Mu left here alone and embarked on an unknown road.

"It's really troublesome. I have been studying technology here for three years and have not practiced much. How come my cultivation has reached the peak of the initial stage of foundation building inexplicably. ”

Li Mu sensed his own cultivation, and a look of surprise appeared on his face.

During these three years, his cultivation had unknowingly reached the peak of the initial stage of foundation building, and he was only half a step away from breaking through.

No wonder the then head of Hengyue Sect said that as long as he practiced seriously, he would be able to break through the golden elixir stage within ten years.

But Li Mu had no interest in cultivation.

In a blink of an eye, Li Mu came to a gathering place for casual cultivators, which was called Tianyun City.

It is said that the first generation of Tianyun City Lord was a golden elixir stage cultivator.

He was also a casual cultivator, and because he felt that it was not easy for casual cultivators to practice, he built Tianyun City here.

To provide some shelter for casual cultivators in the cultivation world.

But that was thousands of years ago It's a thing of the past. The Jindan senior has long turned into dust.

And this Tianyun City has also fallen. It is said that the current city lord is a great man in the late foundation building stage.

Tianyun City is also mainly dominated by cultivators in the Condensation Stage. There are very few people in the foundation building stage, let alone the Jindan stage. There is not even one.

Li Mu walked casually on the streets of Tianyun City. When the cultivators around him saw him.

Everyone couldn't help showing a touch of respect on their faces.

After all, the cultivators in the foundation building stage are senior masters to them. How dare they, the people in the Condensation Stage, not respect them.

Suddenly, Li Mu stopped at a small stall, with a look of doubt in his eyes.

"Daoyou, how much is this thing? "

Li Mu pointed at a ring on the stall and asked in a low voice. The stall owner was a middle-aged man.

After hearing Li Mu's words, he looked up at him and said.

"Five middle-grade spirit stones, no bargaining."

"Five middle-grade spirit stones?"

Li Mu's brows suddenly frowned. Five middle-grade spirit stones, this is enough to be called a sky-high price.

And no matter how you look at the ring, there is nothing special about it. How can it be worth five middle-grade spirit stones?

Thinking of this, Li Mu glanced at the middle-aged man. According to the system's detection,

This man's cultivation has reached the middle stage of foundation building, and he is also a good master.

"DaoyouI really want this thing, please name a new price. "

Li Mu thought for a moment and said sincerely.

The middle-aged man suddenly smiled and reached out to grab the ring.

"Haha, I see that you have a good cultivation level. I just found a secret place recently. If you are willing to explore it with me, I will give you this thing."

"Explore the secret place? "

Li Mu was shocked when he heard this. You know, in the world of cultivation, secret realms left by senior masters are often discovered.

And in these secret realms, there are usually many extremely precious things.

Similarly, these secret realms are also full of dangers. There are various formations and traps left by senior masters, which make people hard to guard against.

So generally, if a cultivator discovers a secret realm, he usually invites his friends to explore it together to increase the survival rate.

"Daoyou, the secret realm you found must be very dangerous!"

Li Mu looked at the man and said calmly.

"Daoyou, what are you talking about? How can a secret realm not be dangerous?".
