Although Cheng Yaojin, Li Jiancheng and others already knew some about the construction data of the Broken Sky Pass, when they really came to the Broken Sky Pass and saw this terrifying Xiongguan, they still gasped and knew about this battle...... It's definitely going to be very hard to beat.

The entire Broken Heaven Pass is about 800 meters long, as if it is a gate, completely blocking the entire Golden Valley Road from south to north, but this is not the most terrifying.

The two cliffs on the Golden Valley Road are about a thousand meters high, and the height of the Broken Sky Pass is just the same as the two cliffs!

That is to say, if you stand below the Broken Heaven Pass and look up, you can hardly see the top of the Broken Sky Pass, because this super male pass...... It's so tall.

What is the situation inside this pass, and what it looks like, it is impossible for outsiders to know at all, because this is the state secret of the Western Slave Empire.

However, if you think about it, just by virtue of the terrifying height of this Xiongguan, if you throw a small pebble down from it, it can definitely kill people...... , not worth your life!

However, fortunately, most of the defensive means of this Xiongguan are all designed for the east, so Cheng Yaojin, Li Jiancheng and others still have a great advantage of attacking from the rear.

Therefore, after seeing the fireworks blooming over Jingu Road, Kou Zhong and Xu Ziling immediately turned into eighty-meter-high water and fire giants respectively, and rushed straight to the giant troop transport passage on both sides of the Broken Sky Pass, leading to the top.

At this moment, on the troop transport passage of the Broken Heaven Pass, there were rows of Western Fierce Slave warriors armed with crossbows, waiting motionlessly for Xu Kou and the others to rush towards him.

Just when Xu Kou and the others had just rushed into the mouth of the Golden Valley, about 300 meters away, and they could rush to the bottom of the Broken Sky Pass, they only heard the clouds and mist above, and suddenly there was a loud sound of "bang——!", and then, countless feather arrows, like rain, fell from the sky and shot at Xu Kou and the others.

Feather arrows that fall from a height of thousands of meters, if they are shot, they must be shot through on the spot and killed in an instant.

What's more, at this time, there were at least more than a thousand feather arrows shot at Xu Kou and the others, almost covering the entire range of the entire Jingu Dao after the Broken Heaven Pass.

Therefore, after seeing this situation, Xu Kou and the others immediately retreated violently, leaving the coverage of all the arrow rain in extreme danger.

"At the top of the cliffs on both sides, it seems that there are indeed archers stationed there, if we want to win this level...... It's not easy. Cheng Yaojin frowned tightly and said to Li Jiancheng and the others beside him.

The attack of Xu Kou and the others just now was actually just a temptation, and the purpose was to find out the situation at the top of the cliff.

The final result is that the valley road more than 400 meters behind the Broken Sky Pass is simply a death zone, and if you want to pass through here to attack the opponent's troop transport channel, you will inevitably have to die a lot of people.

Therefore, after Li Jiancheng frowned and thought for a while, he ordered in a deep voice: "Let the Xuanwu Legion advance towards the passage, and after the arrow rain falls above, retreat immediately." After giving another order to test the attack, everyone looked ahead together, waiting for the result of the Xuanwu Legion's attack.

As a result, the 10,000 Xuanwu warriors all activated their avatars, lined up in a neat array, and began to slowly advance towards the mouth of the Golden Valley.

Xuanwu's defensive ability, that really is not covered, as thousands of arrows rain fell in the sky, it only shot into Xuanwu's back shell about an inch.

Although the thousands of Xuanwu turtles that rushed into the valley road all instantly became Xuanwu porcupines with feather arrows on their backs, they were stunned that none of them were dead, and slowly withdrew from the Golden Valley Road again.

After getting such a result, Cheng Yaojin and the others all frowned tightly, because this result was obviously very bad, and the opponent's feather arrows could shoot into the Xuanwu back shell by about an inch, which was enough to prove the attack power of those arrows...... , how terrible it is.

Therefore, after trying twice in a row, they didn't open the situation, which immediately made Cheng Yaojin and the others all frown tightly.

At this moment, the northern legion in the east must have done its best and is fighting bloodily with the fierce slave warriors guarding the pass, so only by completely taking the Broken Sky Pass as soon as possible can Cheng Yaojin and others lead 600,000 Sui troops as soon as possible to support the northern legion.

However, if you fight hard, it will inevitably cause huge losses, so in the face of such a dilemma, Cheng Yaojin and others all feel a great headache.

"There is no time to continue the temptation, let Kou Zhong and Xu Ziling lead the Xuanwu Legion and the Raging Bull Legion to attack from the front and contain the main force of the enemy. I personally led the Demon Ape Legion to capture the two cliffs, and within half an hour, we must take this pass!" After Su Dingfang finished speaking categorically, he directly turned his horse's head and rushed towards the Demon Ape Legion under his command, completely ignoring whether Cheng Yaojin and the others agreed or not.

Seeing this, Cheng Yaojin frowned slightly, and then said to Li Jiancheng in a deep voice: "Forget it, we don't have time to continue to waste, just follow the plan he said...... , just hit it. After finishing speaking, he waited for Li Jiancheng's answer.

The Xuanwu Legion and the Demon Ape Legion, after all, are the soldiers and horses of Li Jiancheng and Su Dingfang, and although Cheng Yaojin is the supreme commander, it is not easy to force the two to lead the troops to fight to the death.

However, Li Jiancheng still cares about the overall situation in the end, although he is very worried that the fierce slaves are on top of the cliffs on both sides, and he also arranges other defense methods, which ultimately causes Su Dingfang to return in vain, and even suffered heavy losses.

However, after thinking about it for a while, Li Jiancheng sighed heavily and said in a deep voice: "Come on, you can't always try like this." After saying that, he urged his horses to rush to the Xuanwu army in front.

In this way, after quickly setting an attack plan, the Sui army finally began to really exert its strength and launched a fierce attack on Broken Sky Pass.

Kou Zhong and Xu Ziling, each holding a full five shields stacked and bundled together, hid in the array of the Xuanwu Legion, and slowly walked forward in the rain of arrows in the sky.

Seeing that there was still a gap of more than 100 meters, and they were about to approach the two troop transport passages in the north and south, those fierce slave warriors who had been waiting for a long time raised the strong crossbows in their hands and launched a fierce attack on the slowly advancing Xuanwu warriors.

The thumb-thick crossbow arrows shot straight out from the troop transport channel, instantly killing the thousands of Xuanwu warriors at the front of the array, so the Xuanwu warriors in the back pushed the corpses of their comrades, and pushed forward a full fifty meters away without stopping.

Kou Zhong and Xu Ziling each held a shield that was about to shatter, silently calculating the shooting rhythm of the fierce slave warrior, just when the opponent's wave of crossbow arrows was fired, and the next wave of arrow rain was about to shoot again...... , finally embarked on the troop transport channel of the Broken Sky Pass.

Kou Zhong raised his hand and raised a fifty-meter-long flame giant knife, and directly slashed down at the countless fierce slave warriors in front of him, and two seconds later, the hundreds of defenders within fifty meters in front of Kou Zhong were all completely engulfed by the raging flames.

The same is true for Xu Ziling's side, the fifty-meter blue water whip he threw out, although it was not as lethal as Kou Zhong's fire knife, but after the whip was fired, he also drew all the defenders within fifty meters in front of him.

However, they could only beep like a cow, because immediately after, hundreds of crossbow arrows burst directly at the two of them.

Therefore, after lifting the incarnation, the two retreated into the phalanx of the Xuanwu Legion again, and continued to slowly advance towards the top of the passage.
