In fact, Lin Jie is now assembling a primitive timing fuse, the principle is very simple, there is a spring in the metal rod that pulls a firing pin, but the firing pin is pulled by an extremely thin metal wire. Pen & Fun & Pavilion www.biquge.info

There is a chamber in the metal rod that contains a corrosive liquid, and when it is to be used, just pinch the chamber where the liquid is stored, and that liquid will naturally flow into the other chamber and begin to corrode the thin wire.

When the thin wire is corroded by the potion, the firing pin naturally strikes the primer at one end of the rod under the action of the spring, and if the timer is placed in the gunpowder, it can immediately detonate the gunpowder.

With this timer, Lin Jie can easily make a time bomb.

"How long will it take to corrode that wire?"

"A quarter of an hour!"

"Oh!"

Lin Jie agreed, and then flattened the head of one of the metal rods and put it aside.

Immediately, the four of them began to talk about some interesting things, which constantly caused bursts of laughter.

"Smack!" A quarter of an hour later, I heard a snap sound from the metal rod that had been pinched and flattened by Lin Jie, and then an inch-long tongue of fire erupted from the other end.

The timer was perfect!

Seven days, only seven days before Lin Jie went to the Devil's Forest.

Today is the day when He Yichen leads a group of henchmen to inspect this underground world, and it is also the day when Lin Jie is ready to get rid of He Yichen's control over him. Ever since he woke up early in the morning, his heart had fallen into a state of extreme tension. But what made him feel a little strange was that there was a little excitement mixed with the nervousness, and he was going to give that gift to He Yichen today.

"Lin Jie, so early, what are we going to do today?" As soon as Lin Jie pushed open the door of the secret room, Yu Gang surrounded him like a weasel smelling the smell of meat.

Looking at Yu Gang, who looked like a workaholic, Lin Jie was also speechless for a while: "You go and oil those parts one by one, and then wipe them carefully with a soft cloth, I will start the test today!"

"Oh!" Hearing such monotonous work, Yu Gang's face was deflated, but after a while, he didn't know what he thought, and ran back in a hurry.

Lin Jie looked at the other party's back thoughtfully, was silent for a moment, and then went to the important processes of the arsenal to check the past one by one as usual, and he was also responsible for managing the entire arsenal.

"He Yichen and the others should be almost there!" Today is the day when He Yichen routinely came to check the progress of the manufacture and improvement of the thunderbolt gun, for so many days, according to Lin Jie's observation, there was no exception.

Lin Jie walked slowly to the place where the gunpowder was produced casually, and it looked no different from usual, not far away was a pile of gunpowder like a hill, all neatly stacked in boxes.

If so much gunpowder exploded together, it would not have lifted the whole of Garluburg into the sky.

Lin Jie secretly calculated the time, those workers had already started to work normally, and he could be sure that He Yichen and the others would come here in less than a quarter of an hour.

Thinking of this, Lin Jie no longer hesitated, and suddenly there was an extra metal rod in his hand, which was the timer forged by Ou Yeqian for him, which had been placed by him in the Sumeru space.

Lin Jie carefully distinguished the two ends of the metal rod, secretly using soul power, one end of the metal rod had been pinched flat by him.

A spacious room in Fort Gallu was the room where Lin Jie was forced to agree to He Yichen's conditions last time, and He Yichen liked to deal with all kinds of things there every day.

Somehow, today's face didn't look as energetic as usual, but a gloomy face, and Yan Kuan, who was standing behind him, also had a nervous expression on his face.

The atmosphere in the whole room was particularly dull, and after a long time, He Yichen broke the silence.

"Go and call Lin Jie!" He Yichen took a long breath before he said slowly.

"Yes!" Yan Kuan agreed carefully, tiptoed to the door, as if he was afraid of provoking He Yichen's impatience, pushed the door and beckoned to the far side of the corridor, a man in black hurriedly walked a few steps to the front, Yan Kuan whispered a few words, and returned to He Yichen like a ghost.

"Childe, what should we do next?" Yan Kuan looked at He Yichen, who was silent, and came to him for a long time and whispered.

"Hehe, what about the God of War Temple, even if they suspect us, they have no evidence!" He Yichen said coldly.

Yan Kuan's eyes rolled a few times, and he suddenly stepped forward mysteriously and said, "The War God Temple suspects us, could it be because of Lin Jie?"

He Yichen glanced at Yan Kuan, and suddenly smiled: "Don't you like Lin Jie very much?"

"No, no, I'm completely thinking about Childe!" Yan Kuan caught a glimpse of He Yichen's gaze, and suddenly felt a thrill all over his body, and his back was soaked in cold sweat. As for He Yichen, although he has been following him for so long, he still can't figure out his thoughts.

"This matter has nothing to do with Lin Jie, it was someone who was targeted when we were transporting the thunderbolt gun!" He Yichen's voice was very soft, and it didn't seem like he was talking to Yan Kuan at all.

"How's the progress of our tunnels and fortifications?" He Yichen said suddenly.

"It's already been completed, we have so many firearms, even the God of War Temple can't even think of attacking it, not to mention that we still have so many corpse soul soldiers!" Yan Kuan smiled with a smile on his face.

As if he was checking the gunpowder in front of him, Lin Jie casually opened a box containing gunpowder, and churned in the box casually, and the shiny timer that he pinched and flattened was suddenly buried in the gunpowder.

"Lin Jie, what are you doing?" suddenly came from behind him, Lin Jie was extremely nervous, frightened all over his body, and had a thought in his heart to destroy that person.

Lin Jie turned his head suddenly, and saw Yu Gang looking at him suspiciously, and there was a man in black standing behind him. Seeing the man in black, Lin Jie put down the thought in his heart, if he wanted to kill the two of them unknowingly, he couldn't do it, and the man in black was also a cultivator in the late stage of Ning Yuan Realm.

"Why are you so loud? You want to know that I'm checking gunpowder, and if you're not careful, it might explode?" he said, glaring at Yu Gang viciously.

"Uh!" Yu Gang didn't seem to expect Lin Jie to lose such a big temper, and he didn't know what to do with the scorn on his face. He is now in terms of status, his status is not as good as Lin Jie, in terms of battle soul cultivation, and the battle soul cultivation is not as good as Lin Jie, and he always has a feeling of powerlessness in the face of Lin Jie.

"What's the matter, are you done?" Without waiting for Yu Gang to answer, Lin Jie asked.

"It's Gongzi He who wants to invite you!" Yu Gang seemed to grasp a life-saving straw and hurriedly said.

"Oh, you go first, I'll be there later!" Lin Jie's face sank, and he instructed Yu Gang, he had already put the timer in the gunpowder now, and in a quarter of an hour, this place would be razed to the ground?

"Childe has something important to ask for, and please ask Lin Gongzi to go quickly!" the man in black in the back said respectfully.
