Everyone breathed a sigh of relief and marched more than 100 meters, and met two branch passages, Ji Yan and others kept heading to the east.

During this period, Ji Yan himself and others saw dozens of corpses, some of which were scorched and significantly poisoned......

Some only bones and flesh are lost......

The enemy army was so afraid of Gu worms in the underground passage, no wonder Lin La would suddenly call for help.

Except for those who are at the realm and above in the late stage of the Qi Refining Evolution Period, ordinary soldiers will be sent to death even if they enter more!

Liubu is a crossroads, full of pale stone......

This is now directly below the eastern wall of Xianyang, and the ground is full of foundations rather than rock formations!

Ji Yan looked at the mountains and rivers Baisuo, the mountains and rivers Baisuo understood, and Wenxin moved a three-dimensional underground passage map appeared......

Like a beehive, the unobstructed passage stretches open like a spider's web, like a labyrinth, making people dizzy and unable to find the direction.

The whole three-dimensional pattern covers an area 500 meters long and 2 to 300 meters wide, which is where the spiritual awareness and scale of the mountains and rivers are located.

"This ......"

"I still can't cut the block!"

The Trapping Ancestor had a headache and hesitated.

His ability is "Trap", and he can cast spells to break down the passage and block the passage.

However, the surrounding area is full of stones, and the area is a foundation, with a wall above and a rock layer below.

The Empty Ancestor didn't have the strength to shake the east city wall and make it collapse!

"Keep going!"

"Just tell the others to reach within the walls!"

"Let the blacksmiths in the city prepare, and completely seal the passage with iron juice!"

Ji Yan's mental power in the sea was disordered, and many ways appeared, swept away, and finally spoke.

In the previous battle, Ji Yan felt that gravity in this world does not value intelligence, everything is very direct and lacks wisdom, and the battle method is completely straightforward and hard.

After playing strategy, Ji Yan felt that his wisdom and thinking were a little insufficient.

Just by the tunnel battle in front of him, Ji Yan couldn't think of a useful way to deal with it.

It can only be blocked, and the cost of irrigation with iron juice is very high, and I don't believe that the enemy army can still dig through the iron layer.

It can't be done in a short time, and the eastern capital Xianyang only needs to keep it until the arrival of the big merchant reinforcements!

Don't look at the enemy army digging up such a huge underground project, the cost, time, and spirit consumed must be huge, it is better to directly open or collapse the city wall.

The tunnel operation should have started before the arrival of the Flying Tiger rebels, otherwise it would not be possible to dig a tunnel of this scale in just a few days, even if there were barbarian great sacrifices and earth beasts!

Along the way, several of the dozens of passages are very quaint and notably new to the excavations......

It should have existed in the barbarian era, and now it is being used by Huang Feihu!

"Yes!"

Jiang Zhe answered, and told a merchant to leave.

The crowd continued to move forward, and all kinds of corpses were crawling everywhere, including newly dead merchant soldiers, pedantic corpses, and skeletons that could not be timed.

The strange thing is that now that nearly half of the foundation has passed, what I see is full of merchant troops, and they have not encountered any barbarian people!

"Could it be that after the tunnel was discovered, the barbarians abandoned this method?"

The anxious and vigilant Flute Demon kept muttering questions in his mouth.

The mountains and rivers Bai Suo naturally opened his mouth and responded, "The authentic thing is a secret thing, and it has been greatly reduced by the natural effect......

"As long as our deep ditch barrier is closely defended, the tunnel will be completely useless!"

Mr. Mingji, who had been silent and quiet, shook his head and retorted, "Having said that, did we really dig a hundred-zhang deep moat along the inner side of the city wall?"

"How long will that take?"

"What if the enemy digs deeper?"

"Or must it be dealt with at the source!"

"The lord thought of irrigating the outside of the city wall with iron juice before is a good idea, but the cost is a bit big, but it is once and for all!"

"At that time, if you leave a few more strongholds and send people to supervise, you will be able to completely eradicate the underground raid!"

Mr. Mingji and Shanhe Baisuo are the two great Confucian cultivators who followed Ji Yan this time, and they are also the only four great Confucian cultivators with Ji Yan's strength.

Jin Operator will not go to the outpost as a logistician......"

"Lady Red Rose is sitting in Wushuang City, and now the situation is fine, and she has not rebelled and returned to the Demon Sect Alliance!

"Molten Iron Irrigation ......"

"There are twenty-four of our imports, and the enemy army is still unknown, so the feasibility is not high!"

The Flute Demon shook his head and reminded.

Shanhe Baisuo responded as a matter of course, saying: "After sealing the entrance with molten iron, the passage will be filled with gravel, and it is impossible to irrigate it all with molten iron!"

"Buzz, buzz, buzz......"

The Flute Demon didn't reply, and a dense and continuous humming sound came along the passage, causing everyone present to be anxious.

Such a momentum is remarkable, and it is the momentum of a large number of foreign objects......

"Beware!"

"It's a swarm of iron-winged bees!"

Shanhe Baisuo closed his eyes for a moment, and when he opened his eyes, he reminded with fear.

"Iron-winged bees?"

The Snake Sword Ancestor's face changed slightly, and he muttered.

The iron-winged bee is only a human-level mid-to-low-grade insect, comparable to the third or fourth weight and below in the refining period, plus the body is small and weak......

With the formation of Ji Yan and others, a large area can be wiped out with a wave of his hand......

However, the iron-winged bee is superior in number and is one of the dominant populations among the fierce beasts, which is extremely difficult and fierce!

Ji Yan was not afraid, but cautiously asked, "Can you find the barbarian high priest?"

Ji Yan's Confucian cultivator evolutionary realm, only the peak realm of the heart refining evolution period, under the increase of the "Golden Emperor Seal", can be compared to the great Confucian cultivator in the middle of the blue blood pill heart stage, the true spiritual sense in the sea of consciousness is not strong, and it is naturally not as good as the mountains and rivers Baisuo.

Mountains and rivers Baisuo majored in the way of mountains and rivers, and was quite good at exploration!

"I can't find it, now I only know the iron-winged bee colony, a lot of weird Gu insects, as well as iron-armored pythons, pangolins, arrow rats and other strange beasts, and I can't find a beast rider!"

Shanhe Bai Suo closed his eyes and his face was quite ugly for a moment, and he suddenly changed his face and shouted loudly

"Not good!"

"Rewind ......"

"Huh?"

Ji Yan, Trapping Ancestor and the others all frowned and looked at the mountains and rivers in unison.

You can go anywhere in a crowd formation, what's so scary?!

"They actually dispatched the Ten Great Strange Worms of the Ancient Barbarians, aren't they now extinct?"

"It's still there at this time, and there are quite a few of them!"

The old face of the mountains and rivers was pale, and he said anxiously with fear.

He hurriedly explained, "Only the old man has checked that there are five kinds of ancient barbarian insects, such as gold-devouring ants, blood-sucking mosquitoes, blue jade ants, earth knife mantises, and Vientiane butterflies, although the number is not much, far inferior to the iron-winged bee colony, but they are all invincible among the top ten fierce creatures!"

"Ten Ancient Barbarian Worms?"

"It's all like this now, and there can be such a thing?"

The oldest cultivator with the strongest qualifications finally blurted out calmly.

The iron-winged bee is a famous ferocious insect, but it is nothing compared to the ancient barbarian ten insects, and there is no comparison at all!

Legend has it that the Ten Ancient Barbarian Worms were able to evolve to the heaven-level evolution realm, and each of them was comparable to an ancestor in the realm of the refinement evolution stage.

At that time, Emperor Xia Wuxian personally took action and led the world's heroes and hundreds of millions of troops......

The fall of many great evolutionaries and evolutionary powerhouses in the realm of Qi refining evolution, coupled with the terrifying means of moving mountains and reclaiming the sea, burning the sky and boiling the earth, only then did they capture the eastern capital Xianyang and kill the ten ancient barbarian insects.
