Hiding in a dense grass fern, Meng Chen and Alfred looked out towards the river.

The riverside is a moist sandy area no more than a kilometer long and only about fifty meters wide.

Six earth dragons with a height of one and a half meters and a body length of more than six meters are lying quietly in the sand pit at the moment with their eyes closed.

"What are they doing?"

Just as Meng Chen was puzzled, the tail of an earth dragon slowly swayed, revealing the scene in the sand pit.

I saw that in the sand pit nearly one meter deep under the belly of the earth dragon, there were green eggs the size of basketballs.

"Laying eggs? The reason why these earth dragons invaded to the north was actually to come to the sands by the river to lay eggs! Are these earth dragons all mother earth dragons about to give birth? Meng Chen said secretly with a surprised expression.

Immediately, Meng Chen realized that this was a perfect opportunity.

At this time, the six earth dragons are all engrossed in laying eggs, and this is the moment when they are at their least vigilant.

As long as you bring in twelve three-bow bed crossbows, you can easily wipe out these six female dragons!

Thinking of this, Meng Chen immediately signaled to Alfred, asking him to quickly return to the eastern defense line of the city and transfer the soldiers and bed crossbows.

Alfred nodded, and stepped back cautiously.

Not knowing how long the female dragon would lay eggs, Meng Chen waited anxiously in the grass fern.

After about half an hour, Alfred finally led sixty elite soldiers and twelve three-bow bed crossbows to the river.

In the dense grass fern three hundred meters away from the mother dragon, the soldiers carefully lined up twelve three-bow bed crossbows.

Creak! Creak! Creak!

Sixty elite soldiers worked together to turn the winch shaft and slowly pull the strings of the twelve three-bow bed crossbows.

Meng Chen, on the other hand, stared nervously at the six female dragons three hundred meters away, lest they would suddenly become alert and run away.

As the minutes ticked by, the twelve three-bow bed crossbows were finally wounded.

After everything was ready, Meng Chen ordered with a little excitement: "Launch!" ”

Boom~!

After a dull sound, twelve long phantoms shot towards the six female dragons on the sand in an instant.

After hearing the sound of a crossbow salvo from the bed, the six female dragons opened their eyes at the same time, but at this time the twelve crossbow arrows were already close in front of them.

Burst! Burst! Burst......

The sound of a series of crossbow arrows entering the body sounded, and twelve crossbow arrows hit nine of them.

Three of the six female dragons were hit by two crossbow arrows, and they were seriously injured on the spot and fell to the ground unable to move.

Of the other three motherlands who were hit by a crossbow arrow, only one was slightly injured and was able to escape with a thick, long bolt.

Without waiting for Meng Chen's order, Alfred dodged and rushed out of the grass fern bushes, quickly chasing after the fleeing mother dragon.

In order to avoid the counterattack of the mother dragons before they died, Meng Chen ordered the soldiers to continue to wind the bed crossbow.

Not long after, twelve three-bow bed crossbows fired another volley, killing the five female dragons lying on the ground and struggling.

And Alfred also dealt with the escaped mother dragon.

At this time, a message popped up from the light curtain in Meng Chen's mind, "Experience +240, soul power +24!" ”

"The soul power of the mother dragon is the same as that of the vajra orangutan, but the experience is 10 points less than that of the vajra orangutan. It seems that the individual strength of the female dragon is a little weaker than that of the vajra orangutan. This ambush, without a single soldier killed or wounded, was too easy! Meng Chen said with a smile on his face.

Subsequently, Meng Chen and the others returned to the core city with the three-bow bed crossbow and the corpse of the mother dragon.

Due to the poison in the body of the earth dragon, the meat of the earth dragon cannot be eaten.

But the corpses of earth dragons are not without value, their scales, tendons, venom glands, teeth, bone spurs, etc., are all white quality materials.

On top of that, with the tendons of these six female dragons, the City of Hope can add six more three-bow bed crossbows.

As for the eggs laid by the female dragon, Meng Chen did not take them away or destroy them, and even kindly spread sand for these eggs.

Although the ambush of the Mother Earth Dragon this time was very successful, Meng Chen did not get carried away, after all, the City of Hope was still not out of danger.

Back at the town hall, Meng Chen asked Alfred, "Alfred, if every batch of egg-laying female dragons passes through the inner city area in the future, it will be too dangerous for the core city. What do you think should be done? ”

Alfred thought for a moment and replied, "Perhaps we can use bait to lure the female dragon away from the City of Hope and to the spawning grounds on the banks of the Creek. ”

Meng Chen touched his chin and asked, "The female dragons are very vigilant, does this method work?" ”

Alfred shook his head and said, "You'll only know if you try!" ”

Meng Chen nodded and said, "Then give it a try!" You immediately go and prepare the bait, try to prepare as much as possible. ”

"Yes! Your Lord! ”

On the third day after the discovery of the giant earth dragon, the bait was ready, but the mother earth dragon did not come.

"Mother dragons, dare to release my pigeons!" Meng Chen muttered with a little dissatisfaction.

I looked at the sky, and it was already early in the morning.

Meng Chen shook his head helplessly and walked towards the mining site on the east side of the river.

Coming to the exit of the rock rift, through the light curtain in his mind, Meng Chen gave the order to build a parapet.

"-30 gold, -100 stone (gray), start building the parapet (tier 1)!" After 8 hours, the construction was completed! ”

Although the northern mountain pass of Dilong Valley had been blocked, Meng Chen still felt that it was safer to build a parapet.

After this parapet wall is built, Meng Chen will also build a guard tower.

Currently, City of Hope has 250 quarrymen and is able to mine 750 units of stone (gray) per day.

In fact, after the construction of the first section of the inner city wall, Meng Chen had already discovered that the biggest factor affecting the construction of the city wall was no longer the shortage of stone materials but the speed of construction.

It takes half a month to build each section of the wall, and even if two sections of the wall are built at the same time, it will only consume a maximum of 12,000 stone units (gray) per half month.

In other words, only 300 quarrymen were needed to meet the supply of stone for the construction of the inner city wall.

However, fortunately, Meng Chen woke up not too late, and made adjustments to the training of civilians in time.

On the fourth day after discovering the giant earth dragon, Alfred reported to Meng Chen, "Lord Lord, five yellow dots of light have appeared at the edge of the detection map!" ”

"The Mother Earth Dragon is finally here!"

Meng Chen's expression perked up, and he ordered: "Act according to the plan!" ”

"Yes! Your Lord! ”

Alfred quickly led a few soldiers to the edge of the alert range, throwing bait in the area where the mother dragon often invaded, trying to lure the mother dragon to another path.

Since they didn't know the preferences of the mother dragon, Meng Chen and the others prepared a variety of bait, including animal meat, animal blood, insects, fruits, fish meat, rhizomes, and so on.

When the order was given, Meng Chen returned to the town hall and monitored the movements of the mother dragon through the detection map.
