Gongsun Mou's giant crossbow for the special mechanism of the Earth Demon Beast is ready, using Gongsun Qiao's unique technique "Mechanism Overlap" made of it, and the mysterious "Xuanmen Dunjia Mechanism" can be selected when combining the "Xuanmen Dunjia Mechanism", which sounds like a simple job, but its complexity and difficulty can only be known by the Xuanji Gate craftsmen who have experienced it firsthand.

If you want to recombine the same mechanism, the natural instability of its structure leads to extremely easy to fall apart, Gongsun Mou and Gongsun Huang Yan discussed and calculated the travel speed and movement route of the Earth Demon Star Demon Beast, and rushed to the best sniper point around Hufeng Mountain in advance to start the assembly work, the whole process can only be done by Gongsun Mou alone, after all, others have not mastered the craft of combining the same mechanism, Gongsun Mou can not be as practical as Gongsun Qiao, can complete the combination of mechanisms in an instant, it took two days and two nights to complete, If it is under the premise of head-to-head confrontation with the enemy, such a long time is not suitable for actual combat, but fortunately, this time the Star Monster does not actively attack the threat of the crowd, and the movement is regular, easy to predict the movement, so there is such an excellent opportunity.

Gongsun Mou looked at the two places of the Earth Demon Beast and the Lake Wind Mountain in the distance, and said to Gongsun Huang Yan: "Everything is ready, how about launching an attack before the Star Demon Beast approaches the Lake Wind Mountain?" ”

Gongsun Huang Yan: "It's best to hurry, the timing can't be delayed." ”

Gongsun Mou was a little surprised by this answer, and asked: "Huang Yan's predecessor is so anxious about time, is he worried about the safety of the people around Hufeng Mountain?" ”

Gongsun Huang Yan said with a smile: "Hahaha, it's just that there is no need to spend time observing the Star Monster now, and more importantly, the people of Shitang Fort are taking action, their whereabouts have been discovered by the celestial puppets I arranged, in addition to Shi Weihu and Shi Yuting, they also have Xingdou Qiankun disciples, presumably the previous rescue of Shi Weihu was from the hands of Xingdou Qiankun, with their unique skills in astrology, they do have the ability to bypass the sight of the celestial puppets for reconnaissance, if they are the first to crusade against the Star Demonic Beasts, then the Star Soul Martial can fall into their hands...... Why, Senior Brother Mou is still complaining that Senior Brother didn't accompany you back to Longquan Mountain, resulting in being taught a lesson by Shitangbao? ”

Gongsun Mou smiled bitterly and said: "That's just me asking for my own hardship, how can I blame Huang Yan's seniors, what the seniors' previous advice said is extremely true, the people of Longquan Mountain don't need me to come to the rescue at all, it's just my own stupid wishful thinking." ”

Gongsun Huang Yan patted Gongsun Mou on the shoulder and comforted: "Don't be discouraged, after one thing and one wisdom, immortal cultivators are precisely because they get rid of the troubles of the old, weak, sick and disabled, and have a longer life than mortals, not only in martial arts, but also in the realm of life experience and thinking that mortals are difficult to touch. ”

Gongsun Mou said in a low voice: "Do you only do self-interested things...... Thank you for your guidance. ”

On the other side, Shitang Fort and Star Dou Qiankun's preparations for attacking the Earth Evil Star Demon Beast have reached the final stage, and the shape-shifting shadow change charm that is enough for the four people to use has been completed, and the specific plan is to let Shi Weihu bear the brunt of the transfer to the inside of the Earth-Evil Star Demon Beast Mountain Shell, open a tunnel directly to the side of the Demon Beast's body, and then paste the shape-shifting shadow change charm on the three nearby stones respectively, so that the other three people can also teleport inside; If Shi Weihu failed to create a tunnel or had an accident, the rest of the people from the Star Dou Qiankun would immediately teleport him back to discuss the strategy again, and Shi Weihu was also told that in case of danger, he must put on the charm before escaping and then return, because he had prepared multiple plans, the number of shape-shifting spells needed was really a lot.

In order to be able to penetrate the deep multi-layered mountain wall with one blow, Shi Weihu has been subjected to Shi Yuting's "love whipping" during the preparation period, absorbing damage to the Mixed Yuan Vajra Wall to the critical point by being beaten, this is a process that requires close thinking and care, because the more damage energy absorbed by the Mixed Yuan Vajra Wall, the more it will consume the corresponding increase in True Qi to maintain stability, and absorb too much damage before the attack, even Shi Weihu's cultivation level is difficult to withstand the huge consumption, so Shi Yuting only uses a slight attack each time to slowly accumulate energy for Shi Weihu.

And the slight attack that Shi Yuting could think of was ......

"The eldest lady's slap is so powerful, you can feel the boom on Weihu's face!"

"I've already given you fifty slaps, is that enough?"

"The eldest lady can work harder, and Weihu can still bear it."

"It's a bit boring to keep repeating an action, how about kicking it next?"

"Okay, as long as the eldest lady likes Weihu, she will agree."

Not far away, Beidou Yuanchen and Beidou Chenji, who were making charms, had goosebumps all over their bodies after hearing this conversation, and Beidou Chenji asked in a low voice, "You say...... What are they preparing for by sneaking there? ”

Beidou Yuanchen said with an embarrassed face: "Maybe it's Brother Weihu's personal preference, there was a girl who treated him before he went out...... Then he will be full of fighting spirit and fighting spirit. ”

Beidou Chenji: "What do you mean by that......"

Beidou Yuanchen: "Stinky boy, don't pretend to be garlic!" Anyway, don't meddle with things. ”

Beidou Chenji said in pieces: "A little envious, being trampled on by the beautiful hostess like a flower......"

Beidou Yuanchen: "??! ”

Ready, the four of them gathered together, Shi Weihu took the rune paper from Beidou Yuanchen's hand, and after not talking much, he urged to start immediately, and at the last moment of the countdown, Beidou Yuanchen just finished reciting the activation spell when he saw Shi Yuting slam Shi Weihu's back with a palm.

Shi Yuting: "Go on Weihu!" ”

Shi Weihu disappeared without a trace the moment he was knocked away, and then a large stone appeared out of thin air, and the change of position proceeded smoothly.

Beidou Yuanchen said embarrassedly: "Shitangbao's way of seeing off is too ...... It was unique. ”

Hokuto Chenji: "It looks like it hurts...... It seems that Shitangbao's King Kong immovable clothes magic skills want to be successful, and it must be a masochistic enthusiast. ”

Shi Yuting's palm was naturally the last charge to Shi Weihu's hybrid vajra wall, Shi Weihu quickly observed the surrounding environment after entering the inside of the mountain shell, and after a while, he found that the mark left by the Beidou Chenji was aimed in this direction to use the long-standing hybrid vajra palm, and a huge roar and tremor were sent out along with the explosion of the rock wall.

This sound alarmed all the immortal cultivators, including the Xuanji Gate, according to the plan, if Shi Weihu did not return within about a minute or so, it meant that the situation was safe and smooth, and the other three would teleport in together to deal with the Star Demonic Beast.

Gongsun Huang Yan: "Where does this voice come from...... I didn't expect them to really find a way to deal with the Star Beast, we have to act quickly. ”

Gongsun Mou: "I know." ”

Gongsun Mou named it "Iron Cavalry Ballista: Thousands of Armies", which means that the arrows fired are like brave cavalry generals, and no one can stop them all the way.

It is not easy to make a ballista that can penetrate the mountain, the effective distance of the arrows of the general siege crossbow is less than one mile, and the power will be reduced with distance due to the influence of air resistance during the flight, although the firing power provided by the bowstring is huge enough for the arrows to break through the walls and gates, but under its instantaneous reaction force, the arrows will also stop and stop, which obviously does not meet the effect required for this crusade against the star monster. Therefore, in the design of the combination to strengthen the giant crossbow not only in the strength of the bowstring, the use of arrows is also very particular, the arrow used to penetrate the mountain is deliberately transformed into a more easily penetrating hard object of the auger drill type, and the Tianjue "kamikaze blade" combined by it through the true qi reflux to drive rotation, in order to allow the arrow to continue to move forward all the way through the rock, the arrow body is also attached to the five-tube propulsion device, with the true gas as fuel to continue to add kinetic energy to the arrow, each tube of true gas exhausted to abandon the next tube, Only then will you have enough strength to break through the entire mountain.

Gongsun Mou speculated that the "Sweeping Thousand Armies" he developed could have a range of up to 100 miles without obstacles, a hundred times that of ordinary siege crossbows, and such a powerful weapon could only be used against the Star Monster, once it was used against people...... It is no exaggeration to say that a single arrow can destroy all the gates at the front and back of the city and the houses along the way, and directly divide the victory and defeat.

Gongsun Mou: "Launch!" ”

As the name suggests, the spiral arrows shot by the Iron Horse Ballista turned into a horse and slaughtered into the mountain, indestructible and unstoppable, Gongsun Mou and Gongsun Huang Yan each drove their own trap beasts to follow behind, and the destination was directly to the center of the mountain where the Earth Evil Star Demon Beast was located.

After a short wait, Shi Yuting, Beidou Yuanchen, and Beidou Chenji determined that Shi Weihu had landed safely, and they all used shapeshifting shadow change charms to teleport in, and the three of them came to a hollow and spacious stone room, only to see Shi Weihu sitting cross-legged on the ground and waiting for a long time.

Shi Yuting: "Have you found any traces of the Star Demonic Beast?" ”

Shi Weihu gave a thumbs up and pointed behind him and said, "It's right there." ”

After being confirmed, the two of them said in unison: "That's it." ”

Beidou Chenji: "How is it, doesn't it look very weak, a big shellless turtle that can't even walk fast." ”

Beidou Yuanchen added: "However, now that there is a shell, it is still very large, quite tricky. ”

Shi Yuting: "This time, Weihu didn't act alone, I thought you had made a move to the Star Demonic Beast before we came." ”

Shi Weihu touched the back of his head and smiled: "I really have this impulse, as Brother Chensi said, it looks very weak, but after a long time, I don't dare to act rashly." ”

Shi Yuting stretched out his hand to Shi Weihu, and just when Shi Weihu closed his eyes in fright, thinking that he was about to be flicked by the eldest lady's fingers again, he didn't expect to receive a light kiss on the forehead.

Shi Yuting blushed and smiled: "Then I'll praise you once this time." ”

Beidou Chenji kept pulling Beidou Yuanchen's sleeve and said anxiously: "See? Do you see it?! ”

Beidou Yuanchen: "Don't talk about it when you see it!" What are you trying to express?! ”

Beidou Chenji said with tears in his eyes: "Envy wow!! ”

The four of them rushed together to attack the Earth Evil Star Demonic Beast, and sure enough, the seemingly weak Demonic Beast was not so easy to succeed, and the surrounding stones were attacking everyone at high speed, Beidou Yuanchen warned: "Don't waste too much time, you must take down the Earth Evil Star Demonic Beast before the transformation is over, otherwise you will temporarily retreat." ”

Shi Weihu: "Hurry up and come here, I'll cover up!" ”

The unbreakable hybrid vajra wall as protection is very reassuring, and the three of them after the Shi Weihu Hall reorganized the attack, and when they were about to succeed, a huge sound came from nearby, and the shadow of the giant arrow above their heads swept at high speed, and when they came back to their senses, they found that they had broken through the other end of the stone chamber and disappeared without a trace.

Shi Yuting wondered, "What is that??" ”

Beidou Chenji: "Look, there's something coming out of that blasted hole!" ”

Beidou Yuanchen fixed his eyes and said in surprise: "It's the Xuanji Gate!" ”

Gongsun Huang Yan and Gongsun Mou jumped out one after another, Gongsun Huang Yan looked down at the beings below in the air, and calmly ordered: "Yingmei will do it, and leave no room alive." ”

I saw the mechanism puppet Sakura sitting behind her fall from the trap beast, descended vertically and spread her six arms, and stretched out her hands and feet with a total of eight sharp blades ruthlessly stabbing into all parts of the body of the Earth Evil Star Demon Beast, killing her with one blow.

Beidou Chenji was surprised: "What a powerful ......"

Beidou Yuanchen: "Don't be in a daze, run!" ”

Beidou Chenji, who was awakened by Yuanchen's words, found that Sakura's movements had not stopped, jumping up from the back of the Earth Evil Star Demon Beast and attacking it.

After Gongsun Huang Yan landed, he instructed Gongsun Mou: "The enemy is outnumbered, and it is not suitable to fight, take away the Star Soul Martial and retreat quickly." ”

Gongsun Mou: "Okay, let's use the puppet to delay the time first." ”

Gongsun Mou released a huge earth puppet as a cover, although it was not difficult to deal with the sluggish earth puppet with the strength of four people, but in this small space, the earth puppet was like a towering city wall, completely keeping everyone out, which was extremely obstructive.

The death of the Earth Evil Star Demon Beast also means that its power is gradually disappearing, and the two mountains that originally relied on this power to connect begin to fall apart, and the immortal cultivators at the bottom of the center are undoubtedly about to be buried alive due to the collapse of the mountain.
