The Chiefs won their third straight game on Sunday and broke a seven-game losing streak to the Denver Broncos at the same time, finishing with a convincing 29-6 victory to move to 4-5 on the season. 

It was a good day for Chiefs Kingdom. 

Here are 10 observations from the game:

1. The Chiefs defense dominated the first half

The Kansas City Chiefs held the Denver Broncos to 40 total yards of offense in the first half and went into the locker room with a 19-0 lead.

Peyton Manning finished the first half 4 of 15 for 30 yards and 3 interceptions by the hands of Marcus Peters, Sean Smith and Josh Mauga.

Manning had a passer rating of 0 through the first 30 minutes of the game.

It's just the second time in franchise history that the Chiefs had 3 interceptions in the first half, with the last time coming against the Oakland Raiders back in 2011.

The Broncos had as many first downs (3) as they had interceptions in the first half, which sums up how this game went from the beginning.

Since 1991, the Broncos had been shut out in the first half at home just nine times.

2. Chiefs pass defense shuts down Peyton Manning

It might be a day that Peyton Manning remembers for a few reasons.

On one hand, he became the NFL's all-time leading passer early in the first quarter with a 4-yard completion to running back Ronnie Hillman.

He passed Brett Favre's former record of 71,838 career yards passing.  

It's an unbelievable milestone for a Hall of Fame player, but that was just about all that the Chiefs defense would allow for him on Sunday.

Manning finished the game 5 of 20 for 35 yards and 4 interceptions, ultimately giving way to backup Brock Osweiler, who entered the game midway through the third quarter with the Chiefs leading 22-0.

The Chiefs actually had more interception return yards against Manning (37) than he had yards passing (35).

It's the first time the Chiefs have beaten Manning since he arrived in Denver four years ago (1-7).

3. Marcus Peters intercepts Peyton Manning's first pass attempt

Marcus Peters is quickly becoming a thorn in the side of Peyton Manning, one of the greatest quarterbacks in NFL history.

In the Week 2 matchup at Arrowhead, Peters had a pick-six off the future Hall of Famer.

On Sunday, Peters picked off Manning's first passing attempt, which would have broken the NFL's all-time record for career yards passing (Manning needed just 3), but Peters had other plans.

His interception led to a Charcandrick West 4-yard touchdown run.

Peters finished the game with 1 interception and two passes defensed.

4. Chiefs offense immediately went to a physical game plan

It was pretty easy to see what the Chiefs were trying to do early in this game.

They were going with a physical, downhill rushing attack and they were winning the battle in the trenches.

West carried the ball 4 times for 25 yards on the first offensive drive, which ended with a 4-yard touchdown run.

On a crucial third-and-1, the Chiefs went right up the middle with West and he was able to spin off for the first down run.

There were a lot of multiple tight end sets and a good dose of fullback Anthony Sherman on the first couple of drives.

5. De'Anthony Thomas' 36-yard reception leads to field goal

Once he gets a little space, he's gone.

De'Anthony Thomas doesn't need much room, so when he gets the right play call in the right situation, the result is normally a pretty good thing for the Chiefs offense.

With the Chiefs holding a 7-0 lead and having forced a three-and-out on the Broncos second offensive drive, Thomas took the quick screen to the outside 36 yards down the field on second-and-10.

It led to Cairo Santos' 48-yard field goal, which gave the Chiefs a 10-0 lead midway through the first quarter.

6. Sean Smith, Josh Mauga, Ron Parker and Eric Berry get in on the interception action

After Peters had an interception and nearly two more that he broke up, Manning decided to go away from his direction, which didn't net a better result.

Sean Smith picked off Manning on second-and-10 from midfield.

The Chiefs offensive drive after the turnover resulted in a 49-yard field goal by Santos, which gave the Chiefs the 13-0 lead.

After a three-and-out from the Broncos offense, linebacker Josh Mauga got in on the action and intercepted a Manning pass attempt across the middle.

It led to some boos as the Broncos offense ran off the field.

Midway through the third quarter, Manning looked like he changed the play at the line of scrimmage before the snap in an attempt to test Chiefs safety Ron Parker, who was lined up in the slot against Emmanuel Sanders.

Result? Parker makes a fantastic interception up the right sideline that came from an overturned call that Andy Reid challenged.

After Osweiler entered the game for Manning midway through the third quarter, he faced a fourth-and-10 from the Chiefs 20-yard line with a little more than 12 minutes remaining in the game.

The pass was intended for receiver Demaryius Thomas in the end zone but Sean Smith made a great play to get a hand on the ball as it fell into the waiting arms of Eric Berry, who picked up his second interception of the season.

The Chiefs had their fifth interception of the game.

7. Cairo Santos hits 4 field goals in the first half

Earlier in the season, Santos hit 7 field goals against the Cincinnati Bengals, so there was no doubt that he could handle the 4 kicks that went his way in the first half against the Broncos.

While touchdowns are the goal and would have been nice, Santos' consistency helped build a solid lead against the Broncos in the early part of this game.

Santos hit from 48, 49, 34 and 33 yards to help build the early 19-0 lead in the first half.

8. Broncos attempted onside kick to begin the second half

Trailing 19-0 as they were set to kickoff for the second half, the Broncos attempted an onside kick to open up the final 30 minutes of the game.

It was at that point that the Broncos felt like they needed a spark.

Second-year player Daniel Sorensen made a great play to dive on the ball as it came his direction.

9. Justin Houston's two key plays prevent possible points

Early in the second half and on Denver's first offensive possession, Manning faced a third-and-5 from his own 14-yard line.

Running back Ronnie Hillman got loose down the field but Manning wasn't able to get much on the throw as Houston brought the pressure for the Chiefs defense.

Hillman had a couple of steps and had the pass been completed, there's a good chance he would have scored an 86-yard touchdown.

Early in the fourth quarter, Houston's sack of Osweiler on third-and-short all but ensured the Chiefs wouldn't allow any points on a key Broncos drive.

Houston finished the game with 2 sacks and 3 quarterback hits.

10. Chancandrick West's 80-yard touchdown sealed the deal

Alex Smith found Charcandrick West wide open across the middle of the field for an 80-yard touchdown that resulted in a 29-0 lead for the Chiefs early in the fourth quarter.
