The power contained in the Spring Secret Text itself can actually be resized, but this is actually not of much use.

After all, it would be difficult for a great swordsman to come up from a spring that was tens or hundreds of meters underground, even if he tried his best.

And the Spring Eye Secret Text itself naturally does not contain so much power, otherwise wouldn't Luo Ming be able to buy a few as grenades and throw them out to blow up the Great Sword Master?

The most important thing is the core of the Spring Eye Secret Text - that authority.

As the master of the world's springs, Elena, the goddess of springs, is able to mobilize the power of the spring itself, and even a part of the underground water system, with a casual command.

The authority in the Secret Text of the Spring is a one-time credential, and this natural power can be invoked within a limited range.

And this gives the created spring a little bit of particularity.

The spring water opened up by using the secret text of the spring can be said to have a sacred temperament naturally, although there is only a trace of insignificance, maybe the power extracted from a dozen tons of spring water is almost the same as a small bottle of ordinary holy water, and extracting this is a completely loss-making matter.

But this has already achieved the effect that Luo Ming wants.

For normal life, such a small amount of holy power will only be beneficial, of course, this benefit is not great, it is similar to basking in the sun for more than ten minutes every day, and you can become a little healthier.

However, mosquito eggs must be in stagnant water to hatch, and the hatchability rate in flowing living water is extremely low.

If this living water still carries a trace of holy power, then it is really a house leak that coincides with overnight rain, and under the double blow, they will be wiped out!

It didn't even need to kill the larvae, as long as that little bit of divine power interfered with its development, so that it could not quickly grow into a flying, blood-sucking adult, it could only reach the end of its life and die in the water.

According to a rough estimate, less than 1 percent of mosquito eggs can hatch smoothly in living water, and less than 1 percent of the hatched larvae can successfully grow into adult mosquitoes that can suck blood - as a result, the number of mosquitoes will be reduced by tens of thousands of times!

Even though there may be one or two fish that occasionally slip through the net, there are only a few mosquitoes left, which can no longer be called a disaster.

As for the destruction of ecosystems, which human development has been doing so far, and then establishing a new order that benefits itself, it is not bad for Luo Ming this time. Besides, there are only a few animals that feed on mosquitoes, and they are not very important, so let them starve or even become extinct, Luo Ming will not feel much guilt and regret.

Artificial breeding can produce more than 10 tons of fish and meat every year, at least thousands of acres of excellent arable land can be opened up near the lake, and water transportation and naval forces can also be trained in lakes and rivers...... In relation to these obvious interests, a little destruction is a last resort.

Of course, this does not mean that Luo Ming is a person who can sacrifice the environment indefinitely for the sake of development - in fact, there is a rule in his decree that you must not cut down too small trees without permission.

Even on Earth, he would do so for the sake of sustainability. Not to mention that there may be such an existence as "World Will" in this world, if you provoke the wrath of the heavens, it will not end well...... Even if the will of the world would not directly condense a thunderbolt in mid-air, it would be enough for him to drink a pot of anger to anger a few nature-loving gods.

Gradually, the lake began to rise and spread to the surrounding area as the water flowed in.

A month later, the lake had stretched out about 100 meters, and within a month, the mosquitoes were almost extinct - Luo Ming drove five shaved sheep to the lake, turned around and came back, only one of them had a swollen lump.

Next, it's time to open the sluice gate and release the water.

Within a month, as the mosquitoes were not yet completely dead, Luo Ming still forbade his men to approach the lake, and only let them dredge the river outside to connect with the lake.

Now, only a thin earthen dam separates the river from the lake, and occasionally the lake overflows a little from above, like a cup full of water when gently shaken.

Luo Ming immediately sent for someone to plant the gunpowder, and then he told everyone to retreat.

Then he lit the gunpowder with his own hands.

With a muffled thunder, a huge crack suddenly appeared in the soil layer, and the lake water that had been impatient for a long time gushed out of the crack, and also consumed the soil and rocks on both sides of the crack, and in just a few seconds, the entire earth dam fell apart!

Just like the elite cavalry attacking the phalanx, if a gap can be opened, the follow-up soldiers will keep up, and the seemingly indestructible phalanx will be immediately crushed!

In fact, even if this work is handed over to his subordinates, digging the earthen dam with hoes and shovels, as long as they are careful not to be swept away by the river, there is no problem.

But Lormin has fallen in love with the use of gunpowder to cut the ribbon for these big projects.

After all, the use of gunpowder is a reminder to everyone who led them to accomplish such a great feat - after all, gunpowder was "invented" by Luo Ming.

Moreover, it is also a kind of training.

Those veterans who have fought many battles with him are okay, the recruits of the production and construction corps are full of fear of the sound of artillery and the smoke of gunpowder, if they are not allowed to get used to it in peacetime, in case they get to the battlefield, as soon as the artillery is fired, they will fall into chaos, how can this battle be fought?

Of course, the enemies who first see the artillery are similar, and while they are not overly superstitious, they can easily mistake them for powerful magic.

Strange to say, according to Luo Ming's understanding during this time, unless they are well-informed veterans, many ordinary soldiers are not afraid of the rain of swords like flying locusts, but they are afraid of the kind of spells that are very powerful, such as fireballs that can only blow up two or three people.

In any case, as long as your side is used to artillery, and the enemy is relatively unfamiliar with it, it will naturally open up a huge gap on the psychological level.

However, in this way, the consumption of gunpowder is a bit large. Fortunately, the big bat cave was discovered, and Luo Ming also launched a campaign to collect nitrate, so that the people who don't have much work to do at the moment are in charge, and the results can be done, so for a while, the supply of gunpowder can still keep up.

It didn't take long for someone to run from the direction downstream, and although it was still far away, he was already waving his hand and shouting something in an excited voice.

Gradually, the sound was close enough for everyone to hear.

"A new lake has appeared! We, we've done!"

Luo Ming smiled, clenched his fists, and took the lead in cheering.
